Description

Technical Field

[0001] This utility model relates to the field of weeding devices, specifically a weeding device for rice paddies. Background Technology

[0002] Weeds grow in rice paddies, competing with rice for nutrients, water, sunlight, and space, severely affecting the normal growth and development of rice. If weeds are not removed in time, the growth of rice will be restricted, leading to a decrease in yield. Therefore, weeding devices are needed to clear the weeds. Using weeding devices can effectively control the growth of weeds, provide a better growing environment for rice, and thus increase yield.

[0003] During the use of weeding devices, some weeds may become entangled on the surface of the drive shaft. However, weeding devices usually do not have the function of cleaning the drive shaft surface. The entangled weeds will hinder the rotation of the drive shaft, causing the power transmission of the device to be obstructed, thereby reducing the weeding efficiency. In addition, the entangled weeds may also increase the load on the drive shaft. During use, once weeds become entangled on the drive shaft, the user needs to manually stop the machine and then spend time and effort to clean the entangled weeds before continuing to work. This process not only increases the user's labor intensity but also reduces the weeding efficiency. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 As shown, a paddy field weeding device includes a weeding machine body 1. Drive shafts 2 are installed on both sides of the weeding machine body 1, allowing the drive shafts 2 to rotate under the action of the body. Hexagonal wheels 3 are bolted to both sides of the surface of each drive shaft 2, and weed-clearing plates 4 are bolted to the surface of each hexagonal wheel 3. There are six weed-clearing plates 4. When the drive shafts 2 rotate, the hexagonal wheels 3 drive the weed-clearing plates 4 to move, clearing weeds. An installation groove 5 is provided inside the drive shaft 2. A connecting rod 6 is movably connected to one side of the inner wall of the installation groove 5. Connecting parts 7 are hinged to the surface of the connecting rod 6. There are several connecting parts 7, and they are equidistant from each other. A positioning shaft 8 is rotatably connected to the inner wall of the connecting part 7. The two ends of the positioning shaft 8 are fixedly connected to the two sides of the inner wall of the installation groove 5. A cutting blade 9 is bolted to one side of the surface of the connecting part 7. The two sides of the surface of the weeding machine body 1... A connecting frame 11 is bolted to each side, and a mounting box 12 is bolted to the bottom of the connecting frame 11. A sliding plate 10 is slidably connected to one side of the inner wall of the mounting box 12. One side of the inner wall of the mounting box 12 is T-shaped, and the sliding plate 10 is also T-shaped. This design prevents the sliding plate 10 from falling off easily. A transmission mechanism 13 is installed inside the mounting box 12. With the action of the sliding plate 10, the internal parts of the transmission mechanism 13 can run more stably. The transmission mechanism 13 works in conjunction with the connecting rod 6. When the transmission mechanism 13 runs, the connecting rod 6 can move back and forth. When the connecting rod 6 moves, the connecting piece 7 can swing. When the connecting piece 7 swings, the cutting blade 9 can swing. When the cutting blade 9 swings, it can cut the weeds wrapped around the surface of the transmission shaft 2. This action can prevent the weeds from affecting the transmission power of the transmission shaft 2. The distance between the cutting blades 9 is equal to the maximum swing amplitude of the cutting blade 9.

[0023] The transmission mechanism 13 includes an electric motor 131. One side of the surface of the electric motor 131 is bolted to one side of the inner wall of the mounting box 12. The output shaft of the electric motor 131 is bolted to a drive shaft 132, which can rotate under the action of the electric motor 131. The other end of the surface of the drive shaft 132 is bolted to a mounting plate 133, which can rotate when the drive shaft 132 rotates. A transmission rod 134 is bolted to one side of the surface of the mounting plate 133, which can rotate when the mounting plate 133 rotates. 4. The transmission rod 134 is designed in a Z shape. A movable seat 135 is bolted to one side of the surface of the slide plate 10. A C-shaped frame 136 is bolted to the bottom of the movable seat 135. One side of the surface of the transmission rod 134 is movably connected to the inner wall of the C-shaped frame 136. When the transmission rod 134 rotates, the C-shaped frame 136 can move back and forth. When the C-shaped frame 136 moves, it can drive the movable seat 135 to move. The inner wall of the movable seat 135 is rotatably connected to one side of the surface of the connecting rod 6. When the movable seat 135 moves, the connecting rod 6 can move.

[0024] Working principle: When the main body 1 of the weed cutter is running, it can drive the two sides to rotate. When the two side drive shafts 2 rotate, the four hexagonal wheels 3 on the sides rotate. Then, the rotation of the hexagonal wheels 3 can drive the weed-cleaning plate 4 to move. The movement of the weed-cleaning plate 4 can then clean the weeds. Since the connecting rod 6, connecting piece 7, positioning shaft 8 and cutting blade 9 are located inside the drive shaft 2, when the drive shaft 2 rotates, it can drive the internal parts of the drive shaft 2 to rotate. During the cleaning process, weeds may become entangled on the surface of the drive shaft 2. When the weeds become entangled on the surface of the drive shaft 2, the electric motor 131 is turned on. Under the action of the electric motor 131, the weed cutter can clean the weeds. The drive shaft 132 rotates, which in turn drives the mounting plate 133 to rotate. The rotation of the mounting plate 133 then drives the transmission rod 134 to rotate. When the transmission rod 134 rotates, the C-shaped frame 136 reciprocates. The reciprocating movement of the C-shaped frame 136 then drives the moving seat 135 to reciprocate. The reciprocating movement of the moving seat 135 then drives the connecting rod 6 to reciprocate. When the connecting rod 6 reciprocates, the connecting piece 7 swings. The swinging of the connecting piece 7 then drives the cutting blade 9 to swing. The swinging of the cutting blade 9 then cleans the weeds wrapped around the surface of the drive shaft 2.
