Description

Technical Field

[0001] This utility model relates to the field of crop weeding technology, and more specifically, to a rotary physical weeding mechanism. Background Technology

[0002] Many existing weeding techniques employ chemical weeding methods. However, due to the residues left by these methods and their negative impact on crop growth, physical weeding mechanisms are irreplaceable. Existing technologies, such as the one described in application number CN202222275915.6, utilize an open design to prevent weeds from escaping and achieve complete weed eradication. However, this design has the following drawbacks: when clearing weeds between crops, it cannot effectively remove weeds growing vertically between crops in order to avoid them, and it also leaves some blind spots. Utility Model Content

[0003] To address the above deficiencies, this utility model provides a rotary physical weeding mechanism to solve the aforementioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A rotary physical weeding mechanism includes a housing, handles, rollers, crops, and weeds, with the weeds located in the gaps between the crops; The three-pronged cutter bar has three branches arranged radially, with fan-shaped intervals between adjacent branches. The crop is located within the fan-shaped intervals. The three-pronged cutter bar revolves around the central axis and rotates on its own axis, with the fan-shaped intervals passing around the crop. Motor 1 and Motor 2, Motor 1 drives the three-pronged cutter to revolve around the sun, and Motor 2 drives the three-pronged cutter to rotate on its own axis.

[0005] Furthermore, it also includes a rotating box located below the second motor. The upper end of the rotating box is equipped with a fixed tube, and a bearing is installed inside the fixed tube. The fixed tube is fixedly connected to the output end of the second motor through the bearing. A bearing is installed on the side wall of the rotating box. A three-pronged cutter is installed on the inner ring of the bearing. A bevel gear set is installed at one end of the three-pronged cutter. The three-pronged cutter is connected to the second motor through the bevel gear set.

[0006] Furthermore, motor one is installed on the lower surface of the housing. Motor one is a dual-shaft motor. The rotating end of motor one is a worm gear, and a worm wheel that meshes with the worm gear is installed on the side wall of the rotating box.

[0007] Furthermore, a cutting rope is installed on the surface of the three-pronged cutter bar.

[0008] Furthermore, a rubber ring is installed at the base of the three-pronged cutter bar.

[0009] The beneficial effects of this utility model are: the three-pronged cutter bar is designed with a structure of revolution and rotation. The rotation clears weeds, and the revolution of the three-pronged cutter bar, in coordination with the movement of the overall mechanism, allows the three-pronged cutter bar to avoid the position of crops, thus avoiding crops and effectively clearing weeds between crops in the vertical direction.

[0011] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0012] This application provides a rotary physical weeding mechanism; please refer to [reference needed]. Figures 1-3 It includes a shell 1, a handrail 2, a roller 3, crops 4 and weeds 5, with the weeds 5 located in the gaps between the crops 4, and also includes; The three-pronged blades 6 are arranged radially, with fan-shaped intervals 7 between adjacent blades 6. The crop 4 is located within the fan-shaped intervals 7. The three-pronged blades 6 revolve around the sun and rotate on their own axis, and the fan-shaped intervals 7 pass around the crop 4. Motor 1 (8) and Motor 2 (9) are used. Motor 1 (8) drives the three-pronged cutter 6 to revolve around the sun, and Motor 2 (9) drives the three-pronged cutter 6 to rotate on its own axis.

[0013] In practical applications, when in use, the handrail 2 is manually pulled, causing the handrail 2, the outer shell 1, and the entire structure to move. By controlling the rotation of motor 8 and motor 9, motor 8 drives the trident blade 6 to revolve, and motor 9 drives the trident blade 6 to rotate. There are two sets of trident blades 6 that rotate synchronously, and a fan-shaped interval 7 is formed between adjacent trident blades 6. When the trident blade 6 revolves, the crops 4 will pass over the fan-shaped interval 7; this can clear weeds while avoiding interference of the trident blades 6 with the crops 4.

[0014] Reference Figure 1 , Figure 2 , Figure 3It also includes a rotating box 91 located below the second motor 9. The upper end of the rotating box 91 is provided with a fixing tube 92. A bearing 93 is installed inside the fixing tube 92. The fixing tube 92 is fixedly connected to the output end of the second motor 9 through the bearing 93. A bearing 94 is installed on the side wall of the rotating box 91. The triangular cutter 6 is installed in the inner ring of the bearing 94. A bevel gear set 95 is installed at one end of the triangular cutter 6. The triangular cutter 6 is connected to the second motor 9 through the bevel gear set 95.

[0015] In practical applications, the rotation of motor 29 drives the trident blade 6 to rotate via bevel gear set 95. Through the action of bearing 193, the rotating box 91 and motor 29 can rotate relative to each other. When the trident blade 6 rotates, it can remove weeds 5 in the swept area while avoiding contact with crops 4.

[0016] Reference Figure 1 , Figure 2 , Figure 3 Motor 8 is mounted on the lower surface of housing 1. Motor 8 is a dual-shaft motor. The rotating end of motor 8 is a worm 81. A worm wheel 82 that meshes with the worm 81 is installed on the side wall of rotating box 91.

[0017] In practical applications, the rotation of motor 8 drives the rotation of worm gears 81 on both sides, which in turn drives worm wheel 82 and rotating box 91 to rotate. The rotating box then drives the three-pronged cutter bar 6 to revolve.

[0018] Reference Figure 1 , Figure 2 , Figure 3 The surface of the three-pronged cutter bar 6 is fitted with a cutting rope 61.

[0019] In practical applications, the cutting rope 61 can be used to remove weeds 5 more thoroughly.

[0020] Reference Figure 1 , Figure 2 , Figure 3 A rubber ring 62 is installed at the base of the three-pronged cutter bar 6.

[0021] In practical applications, the rubber ring 62 is used to prevent rigid contact with the crop 4.
