[0033] Specifically, a fixing seat 3 is fixedly connected to the rear of the top wall of the shell 1, and the output end of the servo motor 4 is connected to the gearbox 5 by a fixed connection. Under the action of the gearbox 5, the servo motor 4 can flexibly adjust its rotation speed to adapt to different working requirements. The bottom end part of the gearbox 5 is connected to the cutting knife 6 so that it can rotate. The front part of the top wall of the shell 1 is fixedly connected to a connecting frame 7, which provides necessary rotation and height support for the drive of the hydraulic rod 8. The middle part of the connecting frame 7 is rotatably connected to two hydraulic rods 8, and the bottom end part of the hydraulic rod 8 is rotatably connected to the rotating member 9, and the bottom part of the rotating member 9 is rotatably connected to the rotating column 10, so that the bottom end part of the hydraulic rod 8 can drive the rotating member 9, thereby driving the rotating column 10 to move, and the bottom wall part of the rotating column 10 The left and right sides of the rotating rod 12 are rotatably connected to the side panels 13, and the adjacent sides of the two side panels 13 are respectively fixedly connected to the left and right sides of the outer shell 1, so that the side panels 13 can effectively block the weeding work and prevent objects from being rolled in.

Through the rotating cutting knife 6, the auxiliary tool 20 improves the cutting and weeding effect under the rotation of the rotating shaft 19.

[0038] Refer to Figure 1 、 Figure 2 and Figure 5, the extraction mechanism 2 further includes a rubber ring 209. The inner wall of the rubber ring 209 is fixedly installed on the outer wall of the right end of the extraction pipe 202, and the outer wall of the rubber ring 209 is fixedly connected to the left side of the filter box 203, so that the rubber ring 209 improves the service life of the connection of the extraction pipe 202; both the left and right ends of the rear side of the housing 1 are fixedly connected with vertical rods 15, and a push rod 16 is fixedly connected between the two adjacent vertical rods 15, so that the vertical rods 15 and the push rod 16 improve the mobility of the device; both sides of the two side plates 13 that are away from each other are fixedly connected with two connecting seats 17, and universal wheels 18 are fixedly installed on the bottom walls of the multiple connecting seats 17, so that the connecting seats 17 and the universal wheels 18 improve the flexibility of the device movement;

[0039] Specifically, the rubber ring 209 can protect the connection between the extraction pipe 202 and the filter box 203. The vertical rods 15 and the push rod 16 facilitate the pushing of the weeding machine, and the connecting seats 17 and the universal wheels 18 improve the flexibility of the device movement.

[0040] Working principle: When starting the weeding work, by starting the servo motor 4, under the connection of the gearbox 5, the cutting knife 6 rotates, so as to cut the weeds entering the bottom of the housing 1. During the moving process, the stone or dead branches can be blocked by the baffle curtain 11, so as to avoid their entry into the bottom of the housing 1 and the situation that the cutting knife 6 is damaged due to the collision with the stone or dead branches. By starting the hydraulic rod 8, the bottom end drives the rotating member 9 and the rotating column 10 to rotate, so that the baffle curtain 11 can change the inclination angle with the rotating rod 12 as the axis, and a better blocking effect can be achieved, thereby improving the service life of the device. And by starting the extraction fan 201, the extraction head 206 can extract the cut grass clippings and dust, so that the extracted grass clippings and dust enter the interior of the filter box 203, effectively reducing the generation of dust. The grass clippings and dust are blocked by the filter plate 204, avoiding the grass clippings and larger particles from entering the interior of the extraction fan through the extraction pipe 202, thereby reducing the situation that the impeller inside the extraction fan 201 is damaged by larger particles, and further reducing the blockage of the weeding line of sight caused by large dust during weeding.
