Referring to FIG. 1, a tractor 10 is shown pulling a nutrient carrier 12. A flexible hose 14 is connected to a rigid conduit 16 which in turn is mounted to a coulter 18 penetrating below the surface of the ground. A cleaning wheel 20 is provided with its lower edge engaging the coulter 18 below the axis 25 (FIG. 3) of the coulter 18. A closer wheel 22 is provided for closing the soil after the manure or nutrients have been deposited below the ground.
A back-up wheel 24, shown in FIGS. 2, 3, 7, and 8, rotates on the same axis as the axis to the coulters provided by axle 25. The back-up wheel 24 is independently rotatable with respect to the coulter 18. Cleaning wheel 20 includes a rim or flange 26 mounted thereon.
A cleaning wheel axis 28 is provided by an axis which is at the lower end of vertical member 30. A cross member 32 is welded to the upper ends of vertical members 30.
A pair of adjustment bars 34 each include an upper end 36 that is welded to cross member 32 and a lower end 38 that is welded to the lower end of vertical bar 30 and adjustment nuts 39 for adjusting the distance between the welded portion of adjustment bars 34 and the cross member 32. Thus it is possible by turning nut 39 adjust the distance between the lower ends of axles 28.
Furthermore, an adjustment is provided by a square sliding pole 40 (FIG. 3) and by a slide 42 which surrounds the sliding pole 40. A cross bar 41 includes a plug 43 which fits within the lower end of a spring 44 as shown in FIG. 2. A projection 46 extends from the square sliding pole 40 (FIG. 3) so as to make the cleaning wheels 20, the vertical members 30, the cross member 32, the downward projection 35 (FIG. 4), and the sliding pole 40 as a unit. A counter movement is provided by coulters 18 and member 42 so that the cleaning wheels 20 can move relative to the coulters 18. This is provided by the sliding action of slide 42 with respect to sliding pole 40 against spring 44 as shown in FIG. 3.
The closer wheels 22 are provided at the rear of the operation. They provide a closer wheel axis 48 (FIG. 2) therein. A pivot point 50 is provided for the axles 48 so as to provide a pivot axis 50 that applies in the direction of the vehicle. A weld line 52 is provided at the upper end of member 51 so as to provide a weld to the yoke 68.
Links 54 (FIG. 3) include a pivot 56 thereon and a lower end which surrounds axis 25. The upper end pivots about member 56 and provides a pair of bars 58 which extend rearwardly to the rear ends 66 of bars 58. A hold down member 60 is slipped over pins 62 and is secured in place by a clip 64. Thus, the members 58 and the member 50 provide limited movement of the axles 48 (FIG. 2).
Referring to FIG. 6, a limited opening 70 is provided adjacent the upper end of the inflexible member 16 and a larger opening 72 is provided at the lower end of inflexible member 16. Similarly, a tab 74 (FIG. 6 and FIG. 4) is provided and provides limited amount of the manure or nutrient being carried by conduit 16 as indicated by the arrow 76 (FIG. 4). Similarly, the arrow 78 is provided at the lower end 72. The method of operation of the nutrient device is as follows:
The frame is operated in a directional movement on the surface of the ground so that the frame has a rearward end and forward end. The coulter 18 is penetrated below the surface of the ground to a ground penetration level. The rotation of the cleaning wheel 20 about the cleaning wheel axis 28 creates a cleaning wheel 20 having a lower edge extending upwardly to an upper edge. The device is maintained at the lower edge of the cleaning wheel 20 in close proximity or touches the coulter 18 below the coulter axis and above the ground penetration level. The extending of the cleaning wheel 20 upwardly from the lower edge of the cleaning wheel 20 away in spaced relationship from the coulter 18 causes the cleaning wheel 20 to clean the coulter 18. A deposit 80 is made of the manure or nutrient in the trench created by the coulter 18 as it passed downwardly from coulter 18. The orientation of the coulters 18 causes the ground to be lifted as indicated at 82. The closing wheels 22 remove the sod 82 to its original position with manure or nutrient 80 below and sealed below sod 82. This is the result of the cleaning wheels 20 providing the action needed to close the ground as indicated at numeral 80 as indicated in FIGS. 4 and 7. The coulter 18 provides an opening action that opens the trench and yet permits the closer wheels 22 and the cleaning wheels 20 to close the ground after the nutrient 80 has been deposited in the soil.
The nutrient device and method of the present invention constitutes an improvement over prior devices. It includes cleaning wheels 20 that touch and clean the coulters 18. It also includes a manure or nutrients spouts that clean the coulters 18 and which place the manure or the nutrients below the soil. It includes minimization of the manure nutrients smell after the deposit and results in much less smell.
The coulters 18 taper from the front to the back progressively, and also are tapered from the top to the bottom progressively so as to open the trench and permit the deposit of the nutrient 80 therein.
The back-up wheels 24 are disposed at the same angle as the coulters 18 and rotate about the same axis as the coulters 18. Furthermore, as shown in FIG. 7, the back-up wheels 24 are slightly below the lowermost portions of the rims of cleaning wheels 20. The closer wheels 20 are canted inwardly.
The spring 44 provides flexibility between the coulters 18 and the cleaning wheels 20 so as to provide flexibility to the unit.
The spout includes a source of manure or nutrients at a small opening 70 above the lower end of the spouts for spreading on the coulter 18, and has a large opening 72 for depositing the nutrients or the manure on the coulters 18 and for applying beneath the ground. The device is efficient, convenient, and places the manure or nutrients below the ground without smell.
The invention has been shown and described above with the preferred embodiments, and it is understood that many modifications, substitutions, and additions may be made which are within the intended spirit and scope of the invention. From the foregoing, it can be seen that the present invention accomplishes at least all of its stated objectives.
