[0026] Working principle: Before weeding, open the storage cabin 905, take out the storage tank 904, add a sufficient amount of weed inhibitor that has no effect on planted trees into the storage tank 904, then put the storage tank 904 back into the installation body 1, connect the water pump 903, and then start the installation body 1, and the steering wheel 2 drives the whole to start moving. During the working process, the motor 1 601 is started, and the motor 1 601 drives one group of rotating shafts 2 501 to rotate. When the rotating shaft 2 501 rotates, the meshing relationship between the gear 1 503 and the gear 2 504 causes the two groups of rotating shafts 2 501 to rotate, and the crushing blade 502 moves along with the rotating shaft 2 501. 01 rotates, and the rotating shaft 1 302 also rotates under the transmission of the transmission wheel 1 602, the transmission wheel 2 603 and the transmission belt 604.

The sliding slider 703 squeezes the spring 705 when sliding, and the chopped grass falls into the discharge pipe 801. Then the motor 2 803 is started, and the motor 2 803 rotates the rotating shaft 3 804 and the auger blade 805. Driven by the auger blade 805, the chopped weeds are discharged from the discharge hopper 802 to provide fertilizer for the trees. After the fertilizer supply is completed, The baffle 706 is reset by the elastic force of the spring 705. As the installation body 1 moves, the water pump 903 is started, and the weed inhibitor in the storage tank 904 is drawn out through the water pipe and sprayed out from the nozzle 902 on the spray pipe 901. The sprayed weed inhibitor treats the weed area after the weeds are cleared and inhibits the growth of weeds. When the installation body 1 moves driven by the steering wheel 2, the visual sensor 10 and the infrared detector 11 detect the area in front of the installation body 1. When encountering staff or trees, the central control system will disconnect the motor 601 and turn through the steering wheel 2. The broadcaster 12 will remind the surrounding people.
