[0039] Working principle: The driving trolley 1 is driven to move in the tea tree planting area. When the driving trolley 1 detects weeds through the camera 1 30, the weed shoveling assembly is located directly above the weeds by driving the movement of the driving trolley 1. Then, the output end of the oil cylinder 1 4 is controlled to extend, so that the mounting plate 5 moves downward, thereby driving the oil cylinder 2 6 and the shovel 7 to move downward until the bottom of the shovel 7 contacts the soil. Then, the output end of the oil cylinder 2 6 is controlled to extend, thereby driving the shovel 7 to move downward at an angle, so that the roots of the weeds are located between the two shovels 7.

[0040] The output end of the third oil cylinder 12 is controlled to extend to drive the soil crushing trough 10 to move horizontally to just below the shovel 7. The output ends of the two second oil cylinders 6 are then controlled to retract, causing the weeds between the two shovels 7 to fall downward into the soil crushing trough 10 along with their roots and soil. The output end of the third oil cylinder 12 is controlled to reciprocate and retract, causing the multiple soil crushing rods 17 to reciprocate and insert into the soil, thereby crushing the soil. The crushed soil passes through the sieve holes on the screen plate 13 and falls downward into the soil discharge assembly. The weeds and their roots cannot be crushed due to their certain flexibility, so they remain above the screen plate 13, thereby separating the weeds from the soil.

[0041] The output end of the control cylinder 5 23 contracts to drive the adjustment plate 21 to rotate, and then drives the connecting seat 19 to rotate. When the connecting seat 19 rotates, it drives the sieve plate 13 to rotate, and cooperates with the vibration of the vibration motor 18 to discharge the weeds above the sieve plate 13 into the grass storage box 32;

[0042] The soil in the soil crushing trough 10 falls downward through the sieve holes into the soil receiving trough 26. When the weeds are shoveled up by the shovel 7, the valve assembly 28 is opened to discharge a certain amount of crushed soil to fill the pits created by the weeds, thereby repairing the pits created by weeding.

[0043] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
