The other end of the first transmission shaft 504b is in transmission connection with the input end of the speed reducer 301.

[0035] When the rotating motor 502 drives the rotating shaft 401 to rotate, the first bevel gear 502a on the rotating shaft 401 drives the second bevel gear 504c to rotate, and then drives the first transmission shaft 504b to rotate, so as to provide power transmission for the speed reducer 301.

[0036] Preferably, the first transmission member 503 comprises a fixed plate 503a arranged at the middle portion of the bottom plate 101 on both sides, and a connecting shaft 503b rotatably connected with the fixed plate 503a on both sides of the rotating roller 201. The connecting shaft 503b is provided with a first synchronous pulley 503c at one end after penetrating through the rear end of the fixed plate 503a.

[0037] Preferably, the first transmission member 503 further comprises a second support base 503d arranged at the top end of the bottom plate 101, and a second transmission shaft 503e rotatably connected in the second support base 503d through a bearing. The second transmission shaft 503e is perpendicular to the horizontal projection of the first transmission shaft 504b. The second transmission shaft 503e is provided with a fourth bevel gear 503f engaged with the third bevel gear 504d on one side of the outer wall. The second transmission shaft 503e is provided with a second synchronous pulley 504g at the end portion. The second synchronous pulley 504g and the first synchronous pulley 503c are connected through a synchronous belt 504h.

[0038] When the first transmission shaft 504b rotates, the third bevel gear 504d on the outer wall of the first transmission shaft 504b drives the fourth bevel gear 503f on the outer wall of the second transmission shaft 503e to rotate, and then drives the second transmission shaft 503e to rotate. When the second transmission shaft 503e rotates, the second synchronous pulley 504g at the end portion rotates, and then drives the first synchronous pulley 503c at the end portion of the connecting shaft 503b to rotate through the synchronous belt 504h, and then drives the rotating roller 201 to rotate.

[0039] Preferably, the connecting member 304 comprises a first hinged joint 304a and a second hinged joint 304b arranged at the side wall of the rotating frame 303 and the side wall of the connecting block 302b, respectively. The first hinged joint 304a and the second hinged joint 304b are respectively provided with a spherical clamping groove in the inside. The spherical clamping groove is respectively provided with a ball 304c slidingly clamped therein. The two balls 304c are arranged at the end portions of the connecting rod 304d.

[0040] When the connecting block 302b moves horizontally left and right, the connecting rod 304d is driven by the second hinge joint 304b to push and pull the rotating frame 303, thereby realizing the swing rotation of the rotating frame 303.

[0041] Preferably, multiple nozzles 305 are distributed on the side wall of the rotating frame 303.

[0042] A water tank and a water pump can be installed on the top of the base plate 101. After connecting multiple nozzles 305 to the water pump through water pipes, weeding and dust suppression can be carried out at the same time.

[0043] Preferably, a push-pull handrail 104 is provided on one side of the base plate 101.

[0044] The base plate 101 can be moved by pushing and pulling the handrail 104.

[0045] In operation, the rotating motor 502 is turned on, which drives the rotating shaft 401 to rotate, thereby causing the multiple cutting blades 403 on the cutter head 402 to rotate and remove weeds. When the rotating motor 502 drives the rotating shaft 401 to rotate, the first bevel gear 502a on the rotating shaft 401 drives the second bevel gear 504c to rotate, which in turn drives the first transmission shaft 504b to rotate. The rotation of the first transmission shaft 504b provides power to the reducer 301, and the output end of the reducer 301 drives the circular... When disc 302 rotates, it drives rotating column 302a to rotate, causing connecting block 302b to move left and right horizontally. As connecting block 302b moves horizontally, connecting rod 304d is driven by second hinge joint 304b to push and pull rotating frame 303, achieving the swing rotation of rotating frame 303. A water tank and water pump can be installed at the top of plate 101. After connecting multiple nozzles 305 to the water pump via water pipes, it is possible to simultaneously weed and spray water for dust suppression. The wet grass stems and the swaying rotation of the rotating frame 303 can expand the spraying area. When the first drive shaft 504b rotates, the third bevel gear 504d on the outer wall of the first drive shaft 504b drives the fourth bevel gear 503f on the outer wall of the second drive shaft 503e to rotate, which in turn drives the second drive shaft 503e to rotate. When the second drive shaft 503e rotates, it drives the second synchronous pulley 504g at the end to rotate. The second synchronous pulley 504g drives the first synchronous pulley 503c at the end of the connecting shaft 503b to rotate through the synchronous belt 504h, which in turn drives the rotating roller 201 to rotate. When the rotating roller 201 rotates, it drives the multiple rubber strips 202 on the outer wall to rotate. Since the outer surface of the rubber strips 202 is integrally formed with multiple branch-shaped protrusions, the rotation of the multiple rubber strips 202 can lift up the lying grass. The branch-shaped protrusions can effectively pull and lift up the lying grass. As the base plate 101 moves, the lying grass is lifted up and then cut by the cutting blade 403.
