[0002] Weeding devices are machines or equipment used to remove weeds. Common types include weed cutters and tillers. They can remove weeds by mechanical cutting or turning the soil. In poplar nurseries, when weeds grow vigorously and compete with poplar seedlings for water, nutrients and sunlight, and manual weeding is inefficient or costly, weeding devices are used to quickly remove weeds and ensure the normal growth of poplar seedlings.

[0003] According to the utility model patent application CN220693655U, a weeding device for planting radishes in mountainous areas is disclosed. Although this device greatly increases the bottom contact area of ​​the overall mechanism by using a cylindrical roller fixed to a rotating rod in the moving mechanism, and improves the friction of the cylindrical roller by using ball nails on the roller, and allows the operator to adjust the handheld part to the optimal height according to their needs through the telescopic rod in the handheld part, the overall mechanism is simple and lightweight, and is more adaptable to the sloping planting ground and complex geographical environment in mountainous areas. However, the overall configuration is relatively bulky and the layout of the mowing structure has certain dangers. It lacks a safe and lightweight convenient weeding structure, making the weeding device relatively bulky and posing safety hazards during use. Therefore, we provide a lightweight weeding device for poplar seedling nurseries to solve the above problems. Utility Model Content

A drive rod is fixedly connected to the output end of the drive motor. A rotating plate is fixedly connected to the bottom end of the drive rod. A double-edged blade is installed inside the protective ring. The upper surface of the double-edged blade contacts the bottom surface of the rotating plate. Two fastening bolts are installed inside the double-edged blade. The outer surface of each fastening bolt contacts the inner wall of the double-edged blade. A fastening nut is threaded onto the outer surface of each fastening bolt. The bottom end of each fastening nut contacts the upper surface of the rotating plate. A button controller is fixedly connected to the upper surface of the push handle. The drive motor is electrically connected to the button controller via a wire.

[0006] Furthermore, two anti-slip sleeves are fixedly connected to the outer surface of the push handle, and several identical anti-slip protrusions are fixedly connected to the outer surface of each anti-slip sleeve.

[0007] Furthermore, a support is fixedly connected to the upper surface of the push handle, and a pull rod is fixedly connected to the inner wall of the support.

By setting the anti-slip protrusions 4, the anti-slip properties of the outer surface of the anti-slip sleeve 3 can be increased. By setting the anti-slip sleeves 3 and the anti-slip protrusions 4, the anti-slip properties of the outer surface of the handle 1 can be increased together.

[0018] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 A drive motor 203 is fixedly connected to the inner wall of the bracket 201. The drive motor 203 is a mature technology and a suitable and lightweight model can be selected according to actual needs. A drive rod 204 is fixedly connected to the output end of the drive motor 203. A rotating plate 205 is fixedly connected to the bottom end of the drive rod 204. A support 5 is fixedly connected to the upper surface of the push handle 1. A pull rod 6 is fixedly connected to the inner wall of the support 5. By setting the pull rod 6, a rotation base surface can be provided for the suspension structure of the support 5. By setting the support 5 and the pull rod 6, they can work together with the above-mentioned suspension structure to properly suspend and store the entire weeding device.

[0019] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 The protective ring 202 is equipped with a double-edged blade 206 inside. Both sides of the double-edged blade 206 can cut grass. The upper surface of the double-edged blade 206 is in contact with the bottom surface of the rotating plate 205. The support 5 is equipped with a handle 7 inside. The inner wall of the handle 7 is rotatably connected to the outer surface of the pull rod 6. By setting the handle 7, it can rotate around the outer surface of the pull rod 6 inside the support 5. Thus, the external suspension structure can suspend and store the entire weeding device after suspending the handle 7.

[0020] Reference Figure 1 , Figure 2 and Figure 3 The double-edged blade 206 has two fastening bolts 207 inside, and the outer surface of each fastening bolt 207 is in contact with the inner wall of the double-edged blade 206. The outer surface of the protective ring 202 is fixedly connected to the anti-collision sleeve 8, and the outer surface of the anti-collision sleeve 8 is fixedly connected to several identical anti-collision protrusions 9. By setting the anti-collision protrusions 9, the anti-collision effect of the outer surface of the anti-collision sleeve 8 can be increased.

[0021] Reference Figure 2 and Figure 3 Each fastening bolt 207 has a fastening nut 208 threaded onto its outer surface. The bottom end of each fastening nut 208 is in contact with the upper surface of the rotating plate 205. A coupling 10 is fixedly connected to the outer surface of the output end of the drive motor 203. The inner wall of the coupling 10 is fixedly connected to the outer surface of the drive rod 204. By setting the coupling 10, the connection between the output end of the drive motor 203 and the drive rod 204 can be strengthened, thereby increasing the rotational stability of the drive rod 204.

[0022] Reference Figure 1 and Figure 2 A button controller 209 is fixedly connected to the upper surface of the push handle 1. The button controller 209 can be an MCU or an Arduino series. It is small in size, low in cost and low in power consumption, and suitable for miniaturization and embedded applications. It can control multiple components through programming. It can be connected to the control terminal of each electrical component through digital output pins and control the power of each component through analog output pins. Specific control logic and timing can be implemented by writing code. The drive motor 203 is electrically connected to the button controller 209 through wires. An auxiliary bearing 11 is fixedly connected to the inner wall of the bracket 201. The inner ring of the auxiliary bearing 11 is fixedly connected to the outer surface of the drive rod 204. By setting the auxiliary bearing 11, the bracket 201 and the drive rod 204 can be connected, thereby increasing the smoothness of the rotation of the drive rod 204.

[0023] Working principle: During use, the operator holds the push handle 1. The anti-slip sleeve 3 and anti-slip protrusion 4 increase the friction between the hand and the push handle 1, preventing slippage during operation. The drive motor 203 is started by the button controller 209. The power of the drive motor 203 is transmitted to the drive rod 204 through the coupling 10. The auxiliary bearing 11 assists the drive rod 204 to rotate smoothly. The drive rod 204 drives the rotating plate 205 to rotate. The double-edged blade 206, which is fixed to the rotating plate 205 by the fastening bolts 207 and fastening nuts 208, rotates at high speed. The cutting action of the blades removes weeds in the nursery. The protective ring 202 surrounds the outside of the double-edged blade 206, effectively preventing the blades from contacting poplar seedlings, etc. To reduce the risk of accidental cutting, the anti-collision sleeve 8 and anti-collision protrusion 9 outside the protective ring 202 can buffer the device when it collides with hard objects, reducing damage to the structure and extending its service life. When the device needs to be moved or stored, it can be suspended or transported by rotating the handle 7 around the pull rod 6, improving portability. Throughout the process, all components work together to ensure weeding efficiency and improve operational safety through multiple protective structures. At the same time, the lightweight design facilitates flexible movement in the nursery. The entire design of the lightweight weeding device for poplar nurseries effectively solves the problem that the lack of a safe and lightweight convenient weeding structure has led to the weeding device being cumbersome and posing safety hazards during use.
