[0026] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0027] like Figures 1 to 6 As shown, an organic fertilizer radiation ditch application device for orchards of the present invention comprises a traveling trolley, a lifting frame 5 located on the traveling trolley, and side beams 7 slidably connected to the left and right sides of the lifting frame 5. The traveling trolley comprises a vehicle body 1 and crawler walking mechanisms 2 installed on both sides of the vehicle body 1. Walking and steering are achieved through the two crawler walking mechanisms 2. A hydraulic station is also installed on the vehicle body 1 to provide hydraulic power.

[0028] The side beam 7 is located on the left or right side of the lifting frame 5. In this embodiment, the side beam 7 is located on the left side of the lifting frame 5 and on the left side of the left crawler walking mechanism 2, so as to facilitate trenching to the fruit tree position on the left. The other side of the lifting frame 5 is hinged to the walking trolley, that is, the right side of the lifting frame 5 is hinged to the walking trolley, and the hinge axis extends forward and backward, so that the left side of the lifting frame 5 can pitch up and down, thereby driving the side beam 7 to move up and down.

[0029] It also includes a pitch cylinder 6 for driving the lifting frame 5 to pitch up and down. The lower end of the pitch cylinder 6 is hinged to the vehicle body 1, and the upper end is hinged to the lifting frame 5, thereby driving the lifting frame 5 to pitch up and down.

[0030] The side beam 7 is a rectangular tube extending forward and backward, and is located on the left side of the lifting frame 5. The front and rear ends of the side beam 7 are fixedly connected with guide posts 12 extending left and right, and the lifting frame 5 is fixedly connected with guide sleeves adapted to the guide posts 12, thereby realizing the guidance of the side beam 7 sliding left and right.

[0031] It also includes a working cylinder 14 for driving the side beam 7 to move left and right. Two working cylinders 14 are provided and fixed on the lifting frame 5. The telescopic shaft of the working cylinder 14 is connected to the side beam 7, thereby driving the side beam 7 to move left and right.

[0032] Two sliding frames 8 are slidably connected to the side beam 7. The sliding frames 8 are welded with sliding sleeves that are sleeved on the side beam 7, so that the sliding frames 8 can slide forward and backward. The side beam 7 also includes an adjusting oil cylinder 9 that drives the two sliding frames to move synchronously in the opposite directions. The adjusting oil cylinder 9 is fixedly connected to the side beam 7. In order to install the adjusting oil cylinder 9, a mounting plate 11 is welded on the upper end surface of the side beam 7, and the adjusting oil cylinder 9 is installed on the mounting plate 11. The adjusting oil cylinder 9 is located in the middle of the two sliding frames 8, and the adjusting oil cylinder 9 is perpendicular to the side beam 7.

[0033] The telescopic shaft of the adjusting oil cylinder 9 is connected to the two sliding frames 8 through the adjusting connecting rod 10. One end of the adjusting connecting rod 10 is hinged to the telescopic shaft of the adjusting oil cylinder 9, and the other end is hinged to the sliding frame 8, so that the two sliding frames 8 are synchronously moved forward and backward and in opposite directions through the telescopic movement of the adjusting oil cylinder 9.

[0034] The sliding frame 8 is rotatably connected to a rotary trenching mechanism 3 via a vertical rotating shaft. Figure 4 As shown, the rotary ditching mechanism 3 includes a vertical sleeve 31 rotatably connected to the sliding frame 8, a box 36 fixed to the lower end of the sleeve 31, and a cutter head shaft 37 axially connected to the box 36. The sleeve 31 is connected to the inside of the box 36, and the cutter head shaft 37 is horizontally rotatably connected in the box 36, with both ends extending out of the box 36.

[0035] The two ends of the cutter shaft 37 are fixedly connected with trenching cutter discs 34, and the outer ring of the trenching cutter disc 34 is fixedly connected with trenching knives 35. The two trenching cutter discs 34 are symmetrically arranged, and the middle plane of the two trenching cutter discs 34 is also the rotation plane of the rotating trenching mechanism 3. Figure 5 The axis E in.

[0036] The sleeve 31 is provided with a trenching drive mechanism for driving the cutter disc shaft 37 to rotate. The trenching drive mechanism comprises a hydraulic motor 33 fixed to the upper end of the sleeve 31, a trenching worm gear 38 fixed to the cutter disc shaft 37, and a drive shaft 32 connected to the rotating shaft of the hydraulic motor 33, wherein the drive shaft 32 is provided with a trenching worm 39 meshing with the trenching worm gear 38. The drive shaft 32 is vertically axially connected in the sleeve 31.

[0037] A fertilizer discharge pipe 13 located above the ditching mechanism 3 is installed on the sliding frame 8, and a fertilizer box is installed on the vehicle body 1. The waste in the fertilizer box is transported to the fertilizer discharge pipe 13 through the fertilizer discharge device, so that the fertilizer is discharged outward from the fertilizer discharge pipe 13 and discharged into the ditch opened by the rotating ditching mechanism 3. The fertilizer is mixed with soil and then backfilled to achieve fertilization.

[0038] The side beam 7 is provided with a rotation adjustment mechanism 4 that drives the two rotating ditching mechanisms 3 to rotate symmetrically. The rotation adjustment mechanism 4 includes a driving gear 43 axially connected to the sliding frame 8. The axis of the driving gear 43 extends forward and backward. The driving gear 43 drives the rotating ditching mechanism 3 to rotate through the gear assembly. An adjustment motor 41 is fixedly connected to the side beam 7. A spline shaft 42 is connected to the rotating shaft of the adjustment motor 41. The driving gear 43 is connected to the spline shaft 42 through a spline sliding connection. Therefore, when the sliding frame 8 drives the driving gear 43 to move forward and backward, the spline shaft 42 can still maintain the connection with the driving gear 43. When the driving gear slides to any position, the driving gear 43 can be driven to rotate through the spline shaft 42.

[0039] The gear assembly includes an adjusting worm 45 axially connected to the sliding frame 8 and an adjusting worm wheel 46 fixedly connected to the rotary ditching mechanism 3. The adjusting worm 45 extends forward and backward and meshes with the adjusting worm wheel 46. A passive gear 44 meshing with the active gear 43 is fixedly connected to the adjusting worm 45.

[0040] The adjusting worm wheel 46 in this embodiment does not need to be set in a circular shape, but can be set in a sector shape, the center position of the sector shape is fixedly connected to the sleeve 31, and the outer arc surface of the sector shape is meshed with the adjusting worm 45, thereby driving the sleeve 31 to rotate.

[0041] A method for using a radiation furrow application device for organic fertilizer for an orchard, comprising the following steps:

[0042] a. The walking trolley moves in the orchard to the middle position between two fruit trees on its side, so that the two rotating furrowing mechanisms 3 on its side correspond to the two fruit trees respectively; Figure 6 The middle shows the state at the initial trenching.

[0043] b. The side beam 7 is driven to move toward the fruit tree on the side by the working cylinder 14, and the two sliding frames are driven to move synchronously in the forward and backward directions by the adjusting cylinder 9, so that the two rotating ditching mechanisms 3 move toward the two fruit trees in a V-shaped divergent shape and the extended line of the moving path passes through the trunk of the fruit tree. The ditching operation is realized by the two rotating ditching mechanisms 3. During the ditching process, the lifting frame 5 is driven to pitch up and down by the pitching cylinder 6 to adjust the ditching depth;

[0044] c. The two rotary ditching mechanisms 3 are driven to rotate symmetrically by the rotary adjustment mechanism 4, and the angle between the rotation plane of the rotary ditching mechanism 3 and the moving path of the rotary adjustment mechanism 4 is adjusted, so as to adjust the ditching width; Figure 5 As shown, axis D is the moving path of the rotary ditching mechanism 3, and axis E is the rotation plane of the rotary ditching mechanism 3. When axis E and axis D coincide, the ditching width is the smallest. When the angle between axis E and axis D is larger, the ditching width is larger.

[0045] d. During the trenching process, fertilizer falls from the fertilizer outlet pipe 13 into the trench, and the fertilizer is mixed with soil and then backfilled to achieve fertilization.

[0046] Of course, the above description is not limited to the above examples. Technical features not described in the present invention can be achieved by or by using existing technologies, which will not be described here.
