[0005] This utility model provides the following technical solution: an agricultural weeding device, comprising a base, a set of fixing plates fixedly connected to both sides of the bottom end of the base, a limit ring rotatably connected to one end of each fixing plate that is close to the other, a rotating cylinder fixedly connected to the end of the limit ring, a support plate fixedly connected to both sides of the bottom end of the base, a limit post fixedly connected to the bottom end of the support plate, the limit post being in contact with the inner wall of the rotating cylinder, a plurality of long grooves being formed on the outer wall of the rotating cylinder, a motor fixedly installed at the bottom end of the base, a rotating shaft fixedly connected to the output end of the motor, a set of transmission mechanisms provided on the outer wall of the rotating shaft, and the rotating shaft synchronously driving a set of rotating rods to rotate through the transmission mechanisms, rotating plates fixedly connected to both sides of the outer wall of the rotating rods, and weed cutters fixedly connected to the upper and lower ends of the rotating plates.

[0006] Furthermore, a handrail is fixedly connected to the top of the base, a baffle is fixedly connected to one side of the bottom of the base, and a through groove is opened on the outer wall of the limiting column corresponding to the transmission mechanism.

[0007] Furthermore, a limiting groove is formed at the end of the fixing plate corresponding to the limiting ring, and the end of the limiting ring is located in the limiting groove and rotatably connected to it.

[0008] Furthermore, the two ends of the rotating rod are respectively rotatably connected to the fixing plates on both sides of the bottom end of the base, and the rotating rod passes through the limiting post and is rotatably connected to it.

[0009] Furthermore, the transmission mechanism includes transmission wheels fixedly connected to the outer wall of the rotating shaft and the rotating rod, and a belt is sleeved between the transmission wheels.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] This invention uses a handrail to push the base and rotating drum to rotate. When weeds enter the rotating drum through a long trough, the motor drives the rotating shaft to rotate. The rotating shaft drives the rotating rod, rotating plate, and mowing blade to rotate via a belt. The mowing blade cuts and crushes the weeds. The crushed particles leave the rotating drum through the long trough. The rotating drum protects the mowing blade and the operator, preventing damage from contact with stones. At the same time, the mowing blade is kept inside the rotating drum to avoid cutting the operator. After the rotating drum and mowing blade on the front side of the base cut the weeds, the rotating drum and mowing blade on the rear side of the base cut the weeds that were not cut in the front, improving the mowing effect. The simple structure also reduces the later use and maintenance costs. Attached Figure Description

Detailed Implementation

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The weeding device for agricultural planting involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Reference Figures 1-4This utility model provides a weeding device for agricultural planting, including a base 1. A handrail 2 is fixedly connected to the top of the base 1. A set of fixing plates 9 are fixedly connected to both sides of the bottom of the base 1. Limiting rings 4 are rotatably connected to the ends of the fixing plates 9 that are close to each other. Limiting grooves 16 are formed at the ends of the fixing plates 9 corresponding to the limiting rings 4. The ends of the limiting rings 4 are located in the limiting grooves 16 and are rotatably connected to them. A rotating cylinder 5 is fixedly connected to the ends of the limiting rings 4. The rotating cylinder 5 protects the weed cutter 14 and the operator, that is, it prevents the weed cutter 14 from coming into contact with stones and causing damage. Damage is prevented, and the mowing blade 14 is kept inside the rotating drum 5 to avoid cutting the operator. After the rotating drum 5 and mowing blade 14 on the front side of the base 1 cut the weeds, the rotating drum 5 and mowing blade 14 on the rear side of the base 1 cut the weeds that were not cut in the front again, which improves the mowing effect. The simple structure also reduces the later use and maintenance costs. A baffle 3 is fixedly connected to one side of the bottom end of the base 1, and support plates 8 are fixedly connected to both sides of the bottom end of the base 1. A limit post 7 is fixedly connected to the bottom end of the support plate 8. The limit post 7 fits against the inner wall of the rotating drum 5. The limit post 7 controls the rotation of the drum. The base 5 provides support and protects the transmission mechanism 17. Several long grooves 6 are formed on the outer wall of the rotating drum 5. When weeds enter the rotating drum 5 through the long grooves 6, the motor 10 drives the rotating shaft 11 to rotate. The rotating shaft 11 drives the rotating rod 12, rotating plate 13, and grass-cutting blade 14 to rotate via the belt 172. The grass-cutting blade 14 cuts and pulverizes the weeds. The pulverized particles leave the rotating drum 5 through the long grooves 6. The motor 10 is fixedly installed at the bottom of the base 1, and the output end of the motor 10 is fixedly connected to the rotating shaft 11. A transmission mechanism 17 is provided on the outer wall of the rotating shaft 11. Furthermore, the rotating shaft 11 synchronously drives a set of rotating rods 12 to rotate via the transmission mechanism 17. The transmission mechanism 17 includes a transmission wheel 171 fixedly connected to the outer wall of the rotating shaft 11 and the rotating rod 12. A belt 172 is sleeved between the transmission wheels 171. The two ends of the rotating rod 12 are respectively rotatably connected to the fixing plates 9 on both sides of the bottom end of the base 1. The rotating rod 12 passes through the limiting post 7 and is rotatably connected to it. The outer wall of the limiting post 7 is provided with a through groove 15 corresponding to the transmission mechanism 17. The two sides of the outer wall of the rotating rod 12 are fixedly connected to rotating plates 13. The upper and lower ends of the rotating plates 13 are fixedly connected to grass cutters 14.

[0019] The working principle of this utility model is as follows: The base 1 and the rotating drum 5 are rotated by the handrail 2. When the weeds enter the rotating drum 5 through the long groove 6, the motor 10 drives the rotating shaft 11 to rotate. The rotating shaft 11 drives the rotating rod 12, the rotating plate 13 and the grass cutter 14 to rotate through the belt 172. The grass cutter 14 cuts and crushes the weeds. The crushed particles leave the rotating drum 5 through the long groove 6. The rotating drum 5 protects the grass cutter 14 and the operator, that is, it avoids the grass cutter 14 from contacting stones and causing damage. At the same time, the grass cutter 14 is not exposed outside the rotating drum 5 and cuts the operator. After the rotating drum 5 and the grass cutter 14 on the front side of the base 1 cut the weeds, the rotating drum 5 and the grass cutter 14 on the rear side of the base 1 cut the weeds that were not cut in the front again, which improves the grass cutting effect and the simple structure reduces the later use and maintenance costs.
