Title: Frost prevention machine support with adjustable bottom structure

Description:
BACKGROUND 
     Technical Field 
     The present invention relates to a device for the frost prevention machine column, which specifically relates to a fixed device and method of a stand column of the frost prevention machine used in tea (fruit) garden, which belongs to the field of agricultural machinery and technology. 
     Description of Related Art 
     China has a long history of tea planting and drinking. The growth and development of tea trees requires a warm and moist climate. The germination of tea buds in early spring is easy to be affected by cold spell in later spring, which reduces quality and production of the tea. In recent years, research on tea tree frost prevention technology has been carried out rapidly in China. The research shows that frost prevention effect can be achieved by using the frost prevention machine to conduct the airflow disturbance from top to bottom. 
     At present, commonly used methods for fixing the frost prevention machine column are as below. (1) Digging a pit with a certain depth of a location where the frost prevention machine is installed in a manual way. Pouring concrete in the pit, and a top of the concrete is provided with an anchor bolt. A column bottom flange is fixed on a foundation of the concrete by the anchor bolt. The disadvantage of this method is that labor intensity is high, and installation efficiency of the frost prevention machine is low. (2) Use tools to dig pit with a certain depth and a diameter slightly larger than a diameter of the column in the location where the frost prevention machine is installed. The frost prevention machine column is placed in the pit with a body of the column being kept upright, and is buried via filling of soil or concrete after adjusting the direction. The disadvantage of this method is that: in order to guarantee working requirement of the column, the pit can only has the diameter slightly larger than that of the column, such that in late burying, a gap between soil and column is hard to eliminate. The gap will further increase due to vibration and wind generated from the frost prevention machine in the process of using machine, this severely reduces safety usage of using the frost prevention machine performance and work efficiency. To solve the problem of high labor intensity and low efficiency of digging the pit, the present invention provides the base plate punched into the soil to replace the deep pit fixing frost prevention machine, which greatly reduce the labor intensity and improved the installation efficiency of the frost prevention machine. In addition, through search, Chinese utility model patent CN201120394200.1 discloses a fixing device for a stand column of a frost prevention machine for plant, which includes several root stand mechanisms disposed at a bottom of the stand column. The root stand mechanisms include a steel root beam formed by a metal sheet beam transversely bent into trough type, and a U-shaped hoop. A pair of positioning rods is disposed on a middle of the steel root beam. A lower part of the column is positioned between a bunch of positioning rods, which are fixed vertically to the steel root beam through the U-shaped hoop. This method requires digging larger and deeper pits, which increase the labor intensity, and requirement of installation of the device itself is high and cost is relatively high. The common feature of the above method is that it is necessary to dig a small diameter and high precision deep pit in the installation position of frost prevention machine, and it is labor intensive, time consuming and costly. The present invention adopts the method of driving the base plate to insert into the soil to avoid the work of digging deep pits, thus it reduces the labor intensity, and improves the installation efficiency of the frost prevention machine. The height of frost prevention machine to the ground needs to reach 6.7 meters to meet the frost prevention effect of frost prevention machine. Non-standard pipe is adopted in the conventional frost prevention machine column since the standard length of the pipe is 6 meters, which has a high cost. The use of the connecting support provided by the present invention can make the frost prevention machine column adopt standard pipe material, which can save 50% of the fabricating cost. 
     SUMMARY 
     The purpose of the present invention is to provide a simple frost prevention machine support with an adjustable bottom structure, which has a simple structure and is convenient in installation for reducing labor intensity and installation time of the frost prevention machine, and for effectively preventing sink, rotation, and tilt of the frost prevention machine column, thus it can save manufacturing and material costs to improve economic efficiency, and transportation and storage are also convenient.

The connecting support  2  includes an anti-toppling guide barrel  21 , a fixed strut  22 , a rib plate  23 , and a connecting plate  24 . An outer diameter of the anti-toppling guide barrel  21  is 0.5 mm-1 mm smaller than an inner diameter of the fixed strut  22  and an inner diameter of the frost prevention machine column  11 . An outer diameter of the fixed strut  22  is equal to the outer diameter of the frost prevention machine column  11 . An upper end of the fixed strut  22  is provided with small holes for plug welding. An outer end of the connecting plate  24  is provided with gaps. During the assembly, the anti-toppling guide barrel  21  is first installed into the fixed strut  22  and into the frost prevention column  11  with a length of more than 200 mm. The anti-toppling guide barrel  21  and the fixed strut  22  are fixed by the method of plug welding. The fixed strut  22  is welded vertically in a center of the connecting plate  24 . The rib plate  23  is welded between the fixed strut  22  and the connecting plate  24  to enhance anti-torsion ability of the frost prevention machine. The base seat  4  is formed by assembling a base plate  41 , a rotary plate  42 , and a guide rod  43 . The base plates and the rotary plate are rotatably connected between each other. The guide rod  43  is installed in the guide groove  412  on the base plates  41 . The base plates are connected through an upper connecting link  44  and a lower connection link  45 . When installing base plates  41 , dig a shallow pit in a corresponding position. Each base plate  41  and the rotary plate  42  are successively punched into the soil after the location of base plate  41  is determined. When an upper end of the base plates  41  is distant from a bottom side with a height of the rotary plate, punch of the base plates  41  is stopped, and start to exert a downward force to the guide rod  43 . During downward movement of the guide rod under exertion of the force, a tip end thereof outwardly pushes the rotary plate  42  to deviate moving direction of the rotary plate and a base fixed plate. Finally, a shape of the base seat is large at bottom and small at top, which is beneficial to stability of the base seat. When an upper end of the guide rod  43  is at the same horizontal position as the base plates  41 , a hook end of the connecting bolt is hooked to the upper connecting ring  44 , continue ramming downward force to the base plate  41  and the guide rod  43  until a top of the base seat is submerged into a surface of the soil, the holes in the upper end of the guide rod  43  and in the upper end of the guide groove  412  are fixed by the bolt. Afterwards, the connecting support  2  and the base seat  4  are connected and fixed together by the base bolts  3 . Finally, the frost prevention machine column  11  is sleeved on the anti-tilting guide barrel  21 , and the anti-tilting guide barrel  21  and the frost prevention machine column  11  are fixed by the means of plug welding. 
     Preferably, a cross-section shape of the fixed part is rectangular. 
     Preferably, number of the base bolts  4  is 4. 
     Preferably, numbers of the upper connecting rings  44  and the lower connecting rings  45  are respectively  4 . 
     Preferably, fixing methods between the anti-tilting guide barrel  21  and the fixed strut  22 , and between the anti-tilting guide barrel  21  and the frost prevention column  11  are plug welding. 
     The present invention has simple structure and convenient installation. It reduces labor intensity installing, raises anti-torsion ability and anti-dumping ability, and increases work reliability of the frost prevention machine. The use of connecting support enables standard pipe material to replace non-standard pipe material, which was originally used to meet the height of the frost prevention machine, thereby saving nearly 50% of the cost, also, it facilitates transportation and storage. At the same time, installation efficiency and economic benefits of the frosting prevention machine are improved.

     The structure, functionality, and processing of the current invention are further described below with reference to the accompanying drawings and the concrete implementation examples. However, the protective range of this present invention includes but not limited to that. 
     The frost prevention machine support with an adjustable bottom structure according to the present invention can overcome the difficulties of the high precision of digging aperture, deep pit with a small diameter and the backfill compaction in the commonly used fixed installation methods of the frost prevention machine by punching the base seat  4  into the soil, and reduces the labor intensity and improves installation efficiency. The use of connecting support enables the standard pipe can replace the conventional non-standard pipe, which was used to meet the height of the frost prevention machine, thereby greatly saving the fabricating costs, and facilitating to transportation and storage. The hole in the base plate can integrate the soil inside and outside of the base seat into one piece, which enhances the stability of the base seat and reduces the damage to the soil. The present invention provides a device adapted for fixing the frost prevention machine column. 
     When installing the frost prevention machine. Firstly, the base plates  41 , the rotary plate  42 , and the guide rod  43  are assembled and formed. The upper connecting ring  44  and the lower connecting ring  45  are mounted, and the relative movement between the base plates  41  is ensured, in order to facilitate each of the base plates  41  to be punched into the soil successively. At the same time, the upper connecting ring  44  also satisfies a gap between hook ends of the base bolts  3  in the ring. Then, dig a pit of 200 mm-300 mm at the position where the frost prevention machine is installed. Each of the base plates  41  and rotary plate  42  are punched into the soil for 50 mm successively after the location of each of the base plate  41  is determined. When an upper end of the base plate  41  is distant from a ground with a height of the rotary plate, suspends punching of the base plate  41  and starts to exert a downward force to the guide rod  43 . Fourthly, when the guide rod  43  is exerted by the downward force, the rotary plate direction control groove of a bending part at the bottom of the guide rod  43  is movable along the direction control pin shaft. The bending part generates an outward push force to the rotary plate  42  during outwardly sliding, such that a moving direction of the rotary plate  42  deviates from a vertical direction and point downward. Finally, the shape of the base seat is big at bottom and small at top, which is beneficial to the stability of the base seat. Then, continue to exert downward force on the base plates  41  and the guide rod  43 , the base plates  41  and the guide rod  43  are simultaneously submerged into the soil until the top of the base plate is aligned with a surface of the soil, at this time, the upper end of the guide rod is fixed to the guide groove on the upper end of the base plates by bolts, and the hook end of the base bolts upwardly hooks the upper connecting ring  44 . Afterwards, adjusting the position of the connecting support  2  on the base seat  4 , the upper end of the base bolt  3  is placed in a notch of an edge of the connecting plate  24 , and the nut is sleeved on the upper end of the base bolt  3  and is pre-tightened. When the connecting plate  24  attaches a bottom of a shallow pit, use the soil to bury the connecting plate  24 . Due to the outer diameter of the anti-tilting guide barrel  21  is 0.5 mm-1 mm smaller than inner diameter of the frost prevention machine column  11 , a lower end of the frost prevention machine column  11  has small holes for plug welding. Finally, the frost prevention machine column  11  is sleeved on the anti-tilting guide barrel  21 , and the anti-tilting guide barrel  21  and the frost prevention machine column  11  are fixed by the means of plug welding.
