The output end of the first hydraulic cylinder 2 is fixedly installed with a carrier plate 8. A plurality of fork nails 9 are fixed at the bottom of the carrier plate 8. The plurality of fork nails 9 are arranged in a grid pattern, and the lengths of the plurality of fork nails 9 gradually decrease from the center to the periphery, so that the plurality of fork nails 9 can better fork up the soil blocks cut by the arc-shaped cutter 6. Two support plates 10 are fixed on the upper surface of the carrier plate 8. A third hydraulic cylinder 11 is arranged on the support plate 10. The output ends of the two third hydraulic cylinders 11 are fixedly installed with a push plate 12. A through hole 13 for the fork nails 9 to slide is opened on the push plate 12;

[0025] The ground clearance height of the arc-shaped cutter 6 can be adjusted by using the two second hydraulic cylinders 3. With the help of the driving component, the first gear 7 can be driven to rotate. The first gear 7 drives the arc-shaped cutter 6 to rotate 180° by means of the rotating rod 5, so that the arc-shaped cutter 6 cuts into the soil layer to complete the cutting of the pothole soil layer. The first hydraulic cylinder 2 is used to push the plurality of fork nails 9 at the bottom of the carrier plate 8 into the soil layer cut by the arc-shaped cutter 6. With the help of the friction force between the fork nails 9 and the soil layer, the plurality of fork nails 9 under the traction of the first hydraulic cylinder 2 can move the soil blocks away, forcing the pothole to be exposed. The two third hydraulic cylinders 11 can be used to push the push plate 12 downward, so that the push plate 12 presses the soil blocks fork-lifted by the plurality of fork nails 9, facilitating the unloading of the soil blocks from the plurality of fork nails 9.

[0026] Among them, the driving component includes a first fixing block 14. The first fixing block 14 is fixedly installed on the U-shaped seat 4. A fourth hydraulic cylinder 15 is arranged on the first fixing block 14. The output end of the fourth hydraulic cylinder 15 is fixedly installed with a carrier block 16. A rack 17 is fixed at the bottom of the carrier block 16. The rack 17 meshes with the first gear 7;

[0027] The fourth hydraulic cylinder 15 is used to push the rack 17 to move. With the help of the meshing of the rack 17 and the first gear 7, the first gear 7 can be driven to rotate. The first gear 7 can drive the arc-shaped cutter 6 to rotate by means of the rotating rod 5, so that the arc-shaped cutter 6 performs cutting operations on the soil layer.

[0028] Among them, the circumflex branch component includes a bottom plate 18. The upper surface of the bottom plate 18 is rotatably connected to a support column 19 through a bearing. The support seat 1 is fixedly installed at the top of the support column 19. A second gear 20 is fixedly sleeved outside the support column 19. A driving motor 21 is arranged on the bottom plate 18.

A counterweight block 25 is arranged on the top of the bottom plate 18;

[0029] The driving motor 21 is used to drive the third gear 22 to rotate. The third gear 22 meshes with the second gear 20. Therefore, the support column 19 can be driven to rotate. The support column 19 pulls the support seat 1 to carry the soil blocks fork-lifted by multiple fork nails 9 away from above the pit. With the help of the four rollers 24, it is more convenient for the device to transfer positions. The counterweight block 25 can maintain the stability of the device during use and prevent the device from tipping over when transferring the soil blocks.

[0030] The working principle of the utility model:

[0031] During use, with the help of the four rollers 24, the device can be transferred to a designated position. Control the two second hydraulic cylinders 3 to operate, so that the two second hydraulic cylinders 3 push the arc cutter 6 downward to adjust the height of the arc cutter 6 from the ground, thereby controlling the cutting depth and cutting size of the arc cutter 6 on the ground soil layer during the next rotation to meet the requirements of tree planting. Control the two fourth hydraulic cylinders 15 to operate, so that the fourth hydraulic cylinders 15 push the rack 17 to move. With the help of the meshing of the rack 17 and the first gear 7, the rack 17 drives the first gear 7 to rotate during the movement. The first gear 7 drives the arc cutter 6 to rotate through the rotating rod 5, so that the arc cutter 6 rotates 180° to complete the cutting operation of the soil layer;

[0032] Control the first hydraulic cylinder 2 to extend, so that the first hydraulic cylinder 2 pushes the multiple fork nails 9 downward, forcing the multiple fork nails 9 to insert into the soil layer. With the help of the friction between the fork nails 9 and the soil layer, when the first hydraulic cylinder 2 contracts, the multiple fork nails 9 can fork up the soil blocks cut by the arc cutter 6. Control the driving motor 21 to drive the third gear 22 to rotate. With the help of the meshing of the third gear 22 and the second gear 20, the third gear 22 can drive the second gear 20 to rotate while rotating. The second gear 20 drives the support seat 1 to rotate through the support column 19, so that the soil blocks fork-lifted by the fork nails 9 rotate accordingly and the soil blocks move away from above the pit. When it is necessary to unload the soil blocks, the two third hydraulic cylinders 11 can be controlled to extend, so that the two third hydraulic cylinders 11 push the push plate 12 downward. With the help of the push plate 12, the soil blocks fork-lifted on the fork nails 9 are squeezed off, so that the soil blocks are separated from the fork nails 9, thus completing the excavation operation of the pit.
