Title: Adjustment system for blade assembly

Description:
TECHNICAL FIELD 
     The present disclosure relates to a blade assembly. More particularly, the present disclosure relates to an adjustment system for the blade assembly of a motor grader. 
     BACKGROUND 
     Grader machines, often referred to as motor graders, are typically used to displace, distribute, mix, and grade a material, such as soil, over a work surface. Grader machines commonly employ a blade or moldboard to carry out one or more of these functions. Some machines may provide for lateral movement of the blade, thereby allowing the blade to assume various work-related positions relative to the work surface. 
     Commonly, a wear strip is employed between a mounting member and the blade for the blade to slide against. As the wear strip may wear out, adjustment and/or alignment may be required of the wear strip relative to the mounting member and/or the blade. However, adjustment and/or alignment of the wear strip may be a laborious and time intensive process due to complex mounting arrangements around the wear strip. Additionally, multidirectional adjustment may be required between the mounting member and the blade, in turn, increasing labor effort and skill. Hence, there is a need for an improved adjustment system for such applications. 
     U.S. Pat. No. 6,799,640 describes a bearing support arrangement for a grader blade. The bearing support arrangement includes short stroke hydraulic cylinders to compensate for wear between slide bearings and slide rails of the grader blade. The cylinders are pressurized by grease and a grease fitting is provided for each cylinder to provide with an access to allow service by an operator. The cylinders are located in a closed cavity between the bearing support holder and the slide bearing.

     DETAILED DESCRIPTION 
     Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or the like parts. Referring to  FIG. 1 , a side view of an exemplary motor grader  100  is illustrated. The motor grader  100  may be used to displace, spread, distribute, level, and/or grade materials, such as soil, over a work surface  102  during a grading operation. The motor grader  100  includes a frame  104 . The frame  104  defines a front end  106  and a rear end  108  with respect to a direction of travel “T” of the motor grader  100 . The frame  104  supports one or more components of the motor grader  100 . The motor grader  100  includes an enclosure  110  mounted on the frame  104 . The enclosure  110  houses a power source (not shown), such as an engine, batteries, and the like, of the motor grader  100 .

The drawbar  120  includes a second end  128  movably coupled to a mid-portion  130  of the frame  104  via one or more actuators  132 , such as a hydraulic actuator. The actuator  132  may be actuated to raise or lower the second end  128  of the drawbar  120  with respect to the frame  104 , in turn, allowing the grader group  118  to be raised or lowered with respect to the work surface  102 . 
     The circle assembly  122  includes a circle member  134  and an arm  136 . The circle member  134  rotates with respect to the drawbar  120  about a rotation axis R-R′ of the circle member  134 . The arm  136  extends from the circle member  134  and rotates with a rotation of the circle member  134  with respect to the drawbar  120 . The arm  136  extends from the circle member  134  in an axial direction along the rotation axis R-R. In the illustrated embodiment, the circle assembly  122  includes a single arm  136 . In other embodiments, the circle assembly  122  may include multiple arms, such that each of the multiple arms may be disposed spaced apart with respect to one another on the circle member  134 . 
     Referring to  FIGS. 1 and 2 , the blade assembly  124  includes a blade  138 , a support member  140 , and a number of mounting assemblies, such as first mounting assemblies  202 ,  204  and second mounting assemblies  206 ,  208 . In the accompanying figure, two first mounting assemblies  202 ,  204  and two second mounting assemblies  206 ,  208  are shown. It should be noted that, in other embodiments, the blade assembly  124  may include single or multiple first mounting assemblies and/or single or multiple second mounting assemblies, based on application requirements. The blade assembly  124  is mounted to the arm  136  via the support member  140 . The support member  140  is movably coupled to the arm  136 , such that the support member  140  pivots about a pivot axis P-P′ with respect to the frame  104 . 
     The blade  138  is mounted to the support member  140  via each of the first mounting assemblies  202 ,  204  and each of the second mounting assemblies  206 ,  208 . As such, the blade  138  pivots about the pivot axis P-P′ with respect to the frame  104 . Also, the blade  138  slides substantially parallel to the pivot axis P-P′ with respect to each of the first mounting assemblies  202 ,  204  and each of the second mounting assemblies  206 ,  208 . The blade  138  engages the work surface  102  during the grading operation. For purpose of clarity and explanation, the mounting assembly will now be explained with reference to the first mounting assembly  202 . It should be noted that each of the first mounting assembly  204  and the second mounting assemblies  206 ,  208  has a configuration similar to a configuration of the first mounting assembly  202 . 
     The first mounting assembly  202  includes a mounting bracket  210 . The mounting bracket  210  is mounted to the support member  140 . The mounting bracket  210  defines a longitudinal axis X-X′ and a lateral axis Y-Y. The longitudinal axis X-X′ is substantially parallel to the pivot axis P-P. The lateral axis Y-Y′ is substantially perpendicular to the longitudinal axis X-X′ and the pivot axis P-P. The first mounting assembly  202  also includes an adjustment block  212 . The adjustment block  212  is disposed in the mounting bracket  210 . The first mounting assembly  202  also includes two retention plates  214  (only one retention plate  214  shown in the accompanying figure) disposed on opposite ends of the mounting bracket  210  relative to the longitudinal axis X-X. 
     Each of the retention plates  214  is disposed on the mounting bracket  210  in association with the adjustment block  212 . More specifically, each of the retention plates  214  engages with the adjustment block  212  via one or more engaging surfaces (not shown), such as one or more slots, grooves, and so on, provided on the adjustment block  212 . As such, each of the retention plates  214  is adapted to limit longitudinal movement of the adjustment block  212  along the longitudinal axis X-X′ relative to the mounting bracket  210 . Also, each of the retention plates  214  is adapted to allow lateral movement of the adjustment block  212  along the lateral axis Y-Y′ relative to the mounting bracket  210 . 
     The first mounting assembly  202  further includes a wear element  320  (shown in  FIG. 3C ). The wear element  320  is disposed in the adjustment block  212 . The wear element  320  is adapted to slidably receive a surface of the blade  138 , such as a mounting rail  218  of the blade  138 . More specifically, the wear element  320  is adapted to provide a sacrificial wear surface between the mounting rail  218  of the blade  138  and the adjustment block  212 . In an assembled position of the mounting rail  218  on the wear element  320 , the mounting rail  218  limits lateral movement of the wear element  320  and the adjustment block  212  out of the mounting bracket  210  along the lateral axis Y-Y. 
     The first mounting assembly  202  also includes two retention screws  220  (only one retention screw  220  shown in the accompanying figure) disposed on opposite ends of the adjustment block  212  relative to the longitudinal axis X-X. Each of the retention screws  220  is disposed on the adjustment block  212  in association with the wear element  320 . More specifically, each of the retention screws  220  engages with opposite ends of the wear element  320  relative to the longitudinal axis X-X. As such, each of the retention screws  220  is adapted to limit longitudinal movement of the wear element  320  along the longitudinal axis X-X′ relative to the adjustment block  212 . Also, each of the retention screws  220  is adapted to allow lateral movement of the wear element  320  along the lateral axis Y-Y′ relative to the adjustment block  212  and/or the mounting bracket  210 . 
     The blade assembly  124  also includes at least one side shift cylinder  222 . In the illustrated embodiment, the blade assembly  124  includes a single side shift cylinder  222 . In other embodiments, the blade assembly  124  may include multiple side shift cylinders, based on application requirements. The side shift cylinder  222  is disposed on the support member  140  and is operably coupled to the mounting rail  218  of the blade  138 . Based on an extension and a retraction of the side shift cylinder  222 , the side shift cylinder  222  is adapted to slide the blade  138  substantially parallel to the pivot axis P-P′ along the mounting rail  218  with respect to each of the first mounting assemblies  202 ,  204  and each of the second mounting assemblies  206 ,  208 . 
     Referring to  FIG. 3A , the blade assembly  124  also includes an adjustment system  300 . The adjustment system  300  will be hereinafter interchangeably referred to as the “system  300 ”. The system  300  includes an adjustment mechanism  302 . The adjustment mechanism  302  will be hereinafter interchangeably referred to as the “mechanism  302 ”. The mechanism  302  is adapted to adjust the wear element  320  relative to the surface of the blade  138 , such as the mounting rail  218 . As such, the mechanism  302  is disposed in association with the mounting bracket  210  and the wear element  320 . Referring to  FIG. 3B , a schematic representation of the mechanism  302  of the system  300  is illustrated. Referring to  FIG. 3C , another schematic representation of the mechanism  302  showing a cross-sectional view of the first mounting assembly  202  is illustrated. The system  300  and the mechanism  302  will be now be explained with combined reference to  FIGS. 3A, 3B, and 3C . 
     In the illustrated embodiment, the mechanism  302  is a hydraulic adjustment mechanism. Accordingly, the mechanism  302  includes a hydraulic pump  304 . The hydraulic pump  304  is adapted to provide a flow of hydraulic fluid, such as hydraulic oil, within the mechanism  302 . The hydraulic pump  304  may be any fluid delivery pump, such as a piston pump, a gear pump, a gerotor pump, a screw pump, a centrifugal pump, and so on, based on application requirements. The mechanism  302  also includes one or more pistons  306 ,  308  disposed movably within the mounting bracket  210 . More specifically, the mounting bracket  210  includes one or more bores  310 ,  312  adapted to movably receive the one or more pistons  306 ,  308  respectively. 
     In the illustrated embodiment, the mechanism  302  includes two pistons  306 ,  308 . Accordingly, the mounting bracket  210  includes two bores  310 ,  312  disposed adjacent to each other, such that each of the bores  310 ,  312  movably receives each of the pistons  306 ,  308 , respectively. In other embodiments, the mechanism  302  may include single or multiple pistons. Accordingly, the mounting bracket  210  may include single or multiple bores in order to movably receive the single or multiple pistons, respectively. Each of the bores  310 ,  312  and the pistons  306 ,  308  are operably coupled to the hydraulic pump  304 . Accordingly, based on the flow of hydraulic fluid from the hydraulic pump  304  into each of the bores  310 ,  312 , each of the pistons  306 ,  308  is adapted to move in a direction “D1” along the lateral axis Y-Y′ of the mounting bracket  210 . Additionally, each of the pistons  306 ,  308  is operably coupled to the adjustment block  212  and the wear element  320 . Accordingly, based on movement of each of the pistons  306 ,  308  in the direction “D1” along the lateral axis Y-Y′, the adjustment block  212  and the wear element  320  is adapted to slidably move in the direction “D1” along the lateral axis Y-Y′ within the mounting bracket  210 . 
     The mechanism  302  also includes a hydraulic valve  314 . The hydraulic valve  314  is operably coupled to the hydraulic pump  304  and each of the bores  310 ,  312  and the pistons  306 ,  308 . Accordingly, based on an operating position of the hydraulic valve  314 , the hydraulic valve  314  is adapted to control the flow of hydraulic fluid from the hydraulic pump  304  to each of the bores  310 ,  312  and the pistons  306 ,  308 , and vice versa. For example, in a closed position of the hydraulic valve  314 , the hydraulic valve  314  is adapted to limit the flow of hydraulic fluid from the hydraulic pump  304  to each of the bores  310 ,  312  and the pistons  306 ,  308 , and vice versa. Also, in an open position of the hydraulic valve  314 , the hydraulic valve  314  is adapted to allow the flow of hydraulic fluid from the hydraulic pump  304  to each of the bores  310 ,  312  and the pistons  306 ,  308 , and vice versa. 
     The system  300  also includes a controller  316 . The controller  316  may be any control unit configured to perform various functions of the system  300 . In one embodiment, the controller  316  may be a dedicated control unit configured to perform functions related to the system  300 . In another embodiment, the controller  316  may be a Machine Control Unit (MCU) associated with the motor grader  100 , an Engine Control Unit (ECU) associated with the engine, and so on, configured to perform functions related to the system  300 . The controller  316  is communicably coupled to the mechanism  302  and the side shift cylinder  222 . Accordingly, in the illustrated embodiment, the controller  316  is communicably coupled to each of the hydraulic pump  304 , the hydraulic valve  314 , and the side shift cylinder  222 . 
     The controller  316  is configured to receive a signal indicative of actuating the adjustment mechanism  302 . In one embodiment, the controller  316  may receive the signal indicative of actuating the adjustment mechanism  302  based on an operator input. In such a situation, the controller  316  may receive the signal indicative of actuating the mechanism  302  from an operator input device  318  communicably coupled to the controller  316 . The operator input device  318  may be any input device, such as a switch, a lever, a knob, an on-screen button, and so on, based on application requirements. Also, the operator input device  318  may be provided on any location on the motor grader  100 , such as on the frame  104  of the motor grader  100 , within the operator cabin  112 , and so on, based on application requirements. Accordingly, an operator may interact with the operator input device  318  in order to provide the signal indicative of actuating the mechanism  302  to the controller  316 . 
     In another embodiment, the controller  316  may receive the signal indicative of actuating the adjustment mechanism  302  based on a predefined period of time. In one embodiment, the predefined period of time may be predefined number of hours of operation of the motor grader  100 . In another embodiment, the predefined period of time may be predefined number of hours or days from a previous blade adjustment cycle. As such, the predefined period of time may be any predefined time duration, based on application requirements. In one embodiment, the predefined period of time may be stored in an internal memory (not shown) of the controller  316 . In another embodiment, the predefined period of time may be stored in a database (not shown) communicably coupled to the controller  316 . Accordingly, as the predefined period of time may reach or elapse, the controller  316  may receive the signal indicative of actuating the mechanism  302 . 
     Based on the received signal, the controller  316  is configured to lift the blade  138  from the work surface  102 . More specifically, the controller  316  is configured to actuate one or more actuators, such as the actuator  132  or any other actuator associated with the blade assembly  124 . In one embodiment, the controller  316  may be communicably coupled to the one or more actuators  132  in order to actuate the one or more actuators  132  to lift the blade  138  from the work surface  102 . In another embodiment, the controller  316  may be communicably coupled to a dedicated control unit (not shown) associated with the one or more actuators  132 . In such a situation, the controller  316  may actuate the one or more actuators  132  to lift the blade  138  from the work surface  102  via the dedicated control unit. 
     The controller  316  is configured to actuate the adjustment mechanism  302  to force the wear element  320  against the surface of the blade  138 . In the illustrated embodiment, the surface of the blade  138  is the mounting rail  218 . More specifically, the controller  316  is configured to actuate the hydraulic pump  304  to provide the flow of hydraulic fluid within the mechanism  302 . The controller  316  is also configured to actuate the hydraulic valve  314  in the open position. As such, the flow of hydraulic fluid is provided within each of the bores  310 ,  312  provided within the mounting bracket  210 . Accordingly, due to an increasing pressure of the hydraulic fluid within each of the bores  310 ,  312 , each of the pistons  306 ,  308  is forced in the direction “D1” along the lateral axis Y-Y. The movement of each of the pistons  306 ,  308 , in turn, forces the adjustment block  212  and the wear element  320  in the direction “D1” along the lateral axis Y-Y′ against the mounting rail  218 . 
     As shown in  FIG. 3D , the controller  316  is configured to release the adjustment mechanism  302  to unforce the wear element  320  against the surface of the blade  138 . More specifically, the controller  316  is configured to switch the adjustment mechanism  302  to a float mode. In such a situation, the controller  316  is configured to deactivate the hydraulic pump  304  to limit the flow of hydraulic fluid within the mechanism  302 . The controller  316  is also configured to actuate the hydraulic valve  314  in the open position. As such, the flow of hydraulic fluid is limited within each of the bores  310 ,  312  provided within the mounting bracket  210  as shown by elements  322 ,  324 . Accordingly, due to reduced pressure of the hydraulic fluid within each of the bores  310 ,  312 , each of the pistons  306 ,  308  may move in any of the direction “D1” or a direction “D2” along the lateral axis Y-Y′, configuring the wear element  320  in an unforced position. 
     The controller  316  is also configured to actuate the at least one side shift cylinder  222  to move the blade  138  in a first direction “FD”. In the illustrated embodiment, the first direction “FD” is along the longitudinal axis X-X′ or the pivot axis P-P. As the blade  138  is moved to an extreme point in the first direction “FD”, the controller  316  is configured to actuate the at least one side shift cylinder  222  to move the blade  138  in a second direction “SD”. In the illustrated embodiment, the second direction “SD” is substantially opposite to the first direction “FD”. As such, the second direction “SD” is along the longitudinal axis X-X′ or the pivot axis P-P. 
     As the blade  138  is moved to an extreme point in the second direction “SD”, the controller  316  is further configured to lock the adjustment mechanism  302  to retain the wear element  320  against the surface of the blade  138 . More specifically, the controller  316  is configured to actuate the hydraulic valve  314  to the closed position. As such, the flow of hydraulic fluid within the mechanism  302 , such as from each of the pistons  306 ,  308  toward the hydraulic valve  314  and the hydraulic pump  304 , is limited. Accordingly, due to static pressure of the hydraulic fluid within the mechanism  302 , movement of each of the pistons  306 ,  308  in the direction “D2” along the lateral axis Y-Y′ of the mounting bracket  210  is limited. As such, the wear element  320  is retained in a fixed position against the mounting rail  218 . 
     It should be noted that although the mechanism  302  is described herein with reference to the hydraulic pump  304  and the hydraulic valve  314 , the mechanism  302  may include additional elements not described herein, such as one or more switches, fluid lines, sensors, sealing elements, and so on, based on application requirements. It should also be noted that although the system  300  and the mechanism  302  is described herein with reference to the first mounting assembly  202 , in other embodiments, the system  300  and the mechanism  302  may be, additionally or alternatively, disposed in association with one or more of the first mounting assembly  204 , the second mounting assembly  206 , and/or the second mounting assembly  208 . It should further be noted that although the mechanism  302  described herein is the hydraulic adjustment mechanism, in other embodiments, the mechanism  302  may be a pneumatic adjustment mechanism. In such a situation, the controller  316  may be communicably coupled to and may control various components (not shown) of the pneumatic adjustment mechanism, such as a pneumatic pump, a pneumatic valve, and so on, in order to adjust and retain the wear element  320  relative to the mounting rail  218  in a manner similar to that described with reference to the mechanism  302 . 
     In other embodiments, the mechanism  302  may be an electromechanical adjustment mechanism. In such a situation, the controller  316  may be communicably coupled to and may control various components (not shown) of the electromechanical adjustment mechanism, such as an electric actuator/motor, one or more electrical/electronic switches, one or more linkage elements, and so on, in order to adjust and retain the wear element  320  relative to the mounting rail  218  in a manner similar to that described with reference to the mechanism  302 . In yet other embodiments, the mechanism  302  may be an electromagnetic adjustment mechanism.

     INDUSTRIAL APPLICABILITY 
     The present disclosure relates to a method  400  of adjusting the blade  138  of the motor grader  100 . Referring to  FIG. 4 , a flowchart of the method  400  of adjusting the blade  138  of the motor grader  100  using the system  300  and the mechanism  302  is illustrated. At step  402 , the controller  316  receives the signal indicative of actuating the mechanism  302  associated with the blade  138 . In one embodiment, the controller  316  may receive the signal indicative of actuating the mechanism  302  based on the operator input via the operator input device  318  communicably coupled to the controller  316 . In another embodiment, the controller  316  may receive the signal indicative of actuating the mechanism  302  based on the predefined period of time, such as predefined number of hours of operation of the motor grader  100 , predefined number of hours or days from the previous blade adjustment cycle, and so on, based on application requirements. 
     Based on the received signal, the controller  316  is configured to lift the blade  138  from the work surface  102 . More specifically, the controller  316  is configured to actuate one or more actuators  132  associated with the blade assembly  124  in order to lift the blade  138  from the work surface  102 . At step  404 , the controller  316  is configured to actuate the mechanism  302  to force the wear element  320  against the surface of the blade  138 . In the illustrated embodiment, the mechanism  302  is the hydraulic adjustment mechanism. In the other embodiments, the mechanism  302  may be the pneumatic adjustment mechanism, the electromechanical adjustment mechanism, or the electromagnetic adjustment mechanism, or a combination thereof. 
     Accordingly, the controller  316  is configured to actuate the hydraulic pump  304  to provide the flow of hydraulic fluid within the mechanism  302 . The controller  316  is also configured to actuate the hydraulic valve  314  in the open position. As such, the flow of hydraulic fluid is provided within each of the bores  310 ,  312  provided within the mounting bracket  210 . Accordingly, due to the increasing pressure of the hydraulic fluid within each of the bores  310 ,  312 , each of the pistons  306 ,  308  is actuated and forced in the direction “D1” along the lateral axis Y-Y. The movement of each of the pistons  306 ,  308 , in turn, forces the adjustment block  212  and the wear element  320  in the direction “D1” along the lateral axis Y-Y′ against the mounting rail  218 . 
     At step  406 , the controller  316  is configured to release the mechanism  302  to unforce the wear element  320  against the surface of the blade  138 . More specifically, the controller  316  is configured to switch the mechanism  302  to the float mode. In such a situation, the controller  316  is configured to deactivate the hydraulic pump  304  to limit the flow of hydraulic fluid within the mechanism  302 . The controller  316  is also configured to actuate the hydraulic valve  314  in the open position. As such, the flow of hydraulic fluid is limited within each of the bores  310 ,  312  provided within the mounting bracket  210 . Accordingly, due to reduced pressure of the hydraulic fluid within each of the bores  310 ,  312 , each of the pistons  306 ,  308  may move in any of the direction “D1” or the direction “D2” along the lateral axis Y-Y. 
     At step  408 , the controller  316  is also configured to actuate the at least one side shift cylinder  222  to move the blade  138  in the first direction “FD”. As the blade  138  is moved to the extreme point in the first direction “FD”, at step  410 , the controller  316  is configured to actuate the at least one side shift cylinder  222  to move the blade  138  in the second direction “SD”. The movement of the blade  138  in the first direction “FD” and the second direction “SD” while the mechanism  302  is switched in the float mode allows positional adjustment of the wear element  320  and the adjustment block  212  within the mounting bracket  210  relative to dimensional tolerances and/or alignment of the mounting rail  218  of the blade  138 . 
     As the blade  138  is moved to the extreme point in the second direction “SD”, at step  412 , the controller  316  is further configured to lock the mechanism  302  to retain the wear element  320  against the surface of the blade  138 . More specifically, the controller  316  is configured to actuate the hydraulic valve  314  to the closed position. As such, the flow of hydraulic fluid within the mechanism  302 , such as from each of the pistons  306 ,  308  toward the hydraulic valve  314  and the hydraulic pump  304 , is limited. Accordingly, due to static pressure of the hydraulic fluid within the mechanism  302 , movement of each of the pistons  306 ,  308  in the direction “D2” along the lateral axis Y-Y′ of the mounting bracket  210  is limited. As such, the wear element  320  is retained in the fixed position against the mounting rail  218 . 
     The system  300  and the mechanism  302  provide a simple and efficient method of adjusting the blade  138  of the motor grader  100 . As such, the system  300  provides a single touch actuation of the mechanism  302  via the operator input device  318  or automatic actuation of the mechanism  302  via the predefined period of time in order to adjust the blade  138  of the motor grader  100 , in turn, reducing labor effort, reducing service duration, reducing service cost, reducing machine downtime, reducing operational cost, improving productivity, and so on. The system  300  and the mechanism  302  may employ simple and readily or already available components on the motor grader  100 , such as the hydraulic pump  304 , the hydraulic valve  314 , the controller  316 , and so on, in turn, reducing system cost and complexity. The system  300  and the mechanism  302  may be retrofitted on any motor grader with little or no modification to the existing system, in turn, improving usability, flexibility, and compatibility.
