[0034] Working principle: First, when it is necessary to weed the lawn, the height of the transmission seat 1 can be adjusted according to the growth of the lawn. As the driving motor 21 drives the transmission ring 33 to rotate, the weeds on the ground can be cleaned and removed. At the same time, the weeds are shredded under the action of the cutting blade 37 and turned into nutrients to reduce the residual roots. In the process of weeding, the transmission ring 33 can push the telescopic rod 34 to move during the rotation process, which can pull the position of the compression spring 361 to change, and the weeds that are higher than the normal green grass height of the lawn can be stuck in the compression spring 36 1 and the cleaning ring frame 35, and moves with the transmission seat 1 so that the weeds can be uprooted to avoid the situation that the roots remain in the soil. In addition, as the compression spring 361 reciprocates, the weeds can be set between the compression springs 361, and the cutting blades 37 can be used to cut and separate them, and the chopped debris can fall on the lawn and can be used as nutrients. In addition, the position of the transmission ring 33 can be adjusted according to different weeds, thereby adjusting the range of movement of the compression spring 361, and it can adapt to the cleaning of weeds of different lengths, and has good applicability.
