[0020] 1. By setting up a protective mechanism, weeds can be quickly removed while avoiding damage to the weeding blades. The roller shaft and the driving wheel are driven by a driving motor to rotate, and the meshing action between the driving wheel and the driven wheel is used to drive the weeding blades to rotate. The tripod is used to limit the driven wheel to ensure that the position of the weeding blades will not change. The weeding blades can be protected by setting up a protective cover. When an obstacle appears in front, the obstacle first contacts the protective cover and pushes the protective cover to move in the through hole. The support block squeezes the cylinder, and the spring absorbs part of the impact force. The spring resets the cylinder to contact the damping particles to absorb the rebound force, thereby improving the stability of the device and being able to perfectly avoid obstacles.

[0021] 2. By setting up the splicing mechanism, the storage box can be installed quickly, which is convenient for cleaning the debris inside the storage box. The handle drives the bolt to move in the groove, which can drive the semi-circular ball to rotate around the first splicing block, thereby releasing the limit of the semi-circular ball on the splicing block, which is convenient for disassembly of the storage box. The threaded action between the bolt and the handle can fix the position of the handle, so the position of the semi-circular ball can be fixed, thereby improving the stability of the storage box installation.
