[0028] like Figure 2 , Figure 3 As shown, the cutting mechanism 4 includes a motor 1 41 and a motor 2 45, the bottom of the motor 1 41 is fixedly connected to the bottom of the inner wall of the body 1, the output end of the motor 1 41 is fixedly connected to a gear 1 42, the top of the motor 2 45 is fixedly connected to the top of the inner wall of the body 1, the output end of the motor 2 45 is fixedly connected to a threaded sleeve 46, the inner wall of the threaded sleeve 46 is threadedly connected to a threaded rod 47, the bottom of the threaded rod 47 is fixedly connected to a mounting frame 402, the top of the inner wall of the mounting frame 402 is rotatably connected to a rotating shaft 44, the lower part of the rotating shaft 44 is fixedly connected to two cutting blades 43, and the left part of the inner wall of the body 1 is fixedly connected to a fixing plate 49.

[0029] It should be noted that, by starting the second motor 45, the threaded sleeve 46 will be driven to rotate clockwise, and the threaded sleeve 46 and the threaded rod 47 are threadedly connected, thereby driving the threaded rod 47 to move downward, thereby driving the mounting frame 402 to move downward, and at the same time, the limit block 405 slides downward along the limit slot 401, ensuring that the mounting frame 402 does not rotate, making the movement of the mounting frame 402 more stable, thereby making the support plate 48 slide into the support slot 404, stopping the second motor 45, and at this time, the second gear 403 will just keep meshing with the first gear 42, and by starting the first motor 41, the first gear 403 will be driven to move downward.

By pushing the handle 6, the machine body 1 can be moved under the drive of the rear wheel 2 and the front wheel group 3. Under the rotation of the cutting blades 43, the weeds are cut. The motor 1 41 is stopped and the motor 2 45 is started again, so that the threaded sleeve 46 rotates counterclockwise, which will drive the cutting blades 43 to move upward. At the same time, the gear 2 403 will be separated from the gear 1 42. At this time, the cutting blades 43 will not rotate, so as to better protect the crops and achieve a better cutting effect.

[0030] like Figure 2 , Figure 3 As shown, the upper portion of the rotating shaft 44 is fixedly connected with a second gear 403 , the right portion of the second gear 403 is meshed with the left portion of the first gear 42 , and the thickness of the second gear 403 is less than the inner wall height of the mounting frame 402 .

Under the action of the spring 501, the baffle 502 moves upward, thereby blocking the collection box 53, and then the collection box 53 is fixed on the body 1. At the same time, the feed pipe 52 set will pass through the square slot 54 into the collection box 53. By starting the fan 51, an upward wind force will be generated, which will drive the weeds along the feed pipe 52 into the collection box 53, and the cut weeds can be collected.

At the same time, the feed pipe 52 will pass through the square groove 54 and enter the collection box 53. By starting the fan 51, an upward wind force will be generated, which will drive the weeds along the feed pipe 52 into the collection box 53, and then the cut weeds can be collected.
