Description

Technical Field

[0001] This utility model belongs to the field of forestry tool technology, specifically relating to a forestry shade net fixing device. Background Technology

[0002] Shade nets and weed control fabrics are widely used in forestry production. However, traditional methods of fixing these nets and fabrics have many shortcomings. Shade nets, mostly secured with nails, are prone to loosening during use, causing them to detach from the plants and shift. Currently, anti-detachment nails are widely used to improve the fixing effect. While they offer some stability and prevent detachment, they still have several drawbacks. For example, some nails have anti-detachment wings on their surface. Although these wings provide some protection, they damage the soil structure along the way during driving, requiring the surrounding soil to be re-compacted, making them cumbersome and difficult to remove. Utility Model Content

[0003] Based on the problems mentioned in the background technology above, this utility model provides a forestry shade net fixing device to solve the problems of traditional anti-loosening fixing devices being easy to loosen and difficult to pull out during the removal of anti-loosening nails due to the obstruction of anti-loosening wings.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A forestry shade net fixing device includes a fixing cone, a linkage rod slidably passing through the fixing cone, a pressure plate at the top of the linkage rod, and several mounting slots on the fixing cone. Each mounting slot contains an anti-detachment component, which includes an integrally formed anti-detachment block and a transmission block. The linkage rod has a corresponding groove, including a transmission slot and a reserved slot. The transmission block is located within the transmission slot. A guide post is located at the top of the fixing cone, and a connecting hole matching the guide post is provided on the pressure plate. The guide post passes through the connecting hole and connects to a top block. A slot is provided at the bottom of the top block. When the anti-detachment component is retracted into the mounting slot, the pressure plate separates from the top block.

[0006] Based on the above technical solution, the present invention has made the following improvements:

[0007] Furthermore, the top of the anti-detachment block has an arc-shaped structure that matches the top of the mounting groove. Even after the anti-detachment block rotates out of the mounting groove, it can still cover the mounting groove to prevent a large amount of soil from entering the mounting groove and the interior of the fixing cone, thus affecting the return of the anti-detachment block to its original position.

[0008] Furthermore, the top of the anti-detachment block has several toothed grooves. These grooves increase the frictional resistance at the top of the anti-detachment block, which helps to improve the anti-detachment effect.

[0009] Furthermore, the top block is equipped with a pry plate, the thickness of which is less than the height of the slot. When removing the fixing device, the pry plate from another fixing device can be used to pry it into the slot, eliminating the need to carry additional tools to pry apart the pressure plate and the top block, making it convenient to use.

[0010] Furthermore, the top block has a threaded hole, and the guide post has a through hole that matches the threaded hole. The top block is fitted onto the guide post, and screws pass through the threaded hole and the through hole. The top block is easy to disassemble, facilitating disassembly and maintenance after the pry bar has deformed.

[0011] The beneficial effects of this utility model are:

[0012] 1. After the fixing device is driven into the soil, the shade net is also pressed by the pressure plate. When the pressure plate contacts the shade net that is in contact with the ground and cannot continue to descend due to the ground, the slot on the linkage rod can push the transmission block to rotate and extend as the top block continues to descend. This causes the anti-detachment block to extend and be inserted into the soil to prevent the fixing cone from coming off and loosening, so as to better fix the shade net.

[0013] 2. During the driving of the fixing device, the slot on the linkage rod applies downward pressure to the transmission block, which keeps the anti-detachment block stored in the installation slot. This prevents the anti-detachment block from damaging the soil outside the fixing cone during the driving of the fixing cone, thereby improving the anti-detachment effect.

[0014] 3. When it is necessary to disassemble the shade net, use a pry tool to insert it into the slot and pry the top block upward with the pressure plate as the base to separate the pressure plate from the top block. As the fixed cone rises, the transmission block can be restricted to rise and rotate through the slot on the linkage rod, so that the anti-detachment block is put into the installation slot, preventing the anti-detachment block from obstructing the fixed cone from leaving the soil, and making it easy to remove.

Detailed Implementation

[0027] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] like Figures 1-9 As shown, a forestry shade net fixing device includes a fixing cone 1. The upper part of the fixing cone 1 is cylindrical and the bottom is conical. A linkage rod 3 is slidably inserted inside the fixing cone 1, and a pressure plate 31 is provided at the top of the linkage rod 3. Several mounting slots 12 are formed on the fixing cone 1, and anti-detachment components 2 are hinged in each mounting slot 12. The anti-detachment component 2 includes an integrally formed anti-detachment block 21 and a transmission block 22. By pushing the transmission block 22 to rotate, the anti-detachment block 21 can be rotated to extend or retract into the mounting slot 12. The linkage rod 3 has a groove corresponding to the anti-detachment component 2. The groove includes a transmission slot 331 and a reserved slot 332. The transmission block 22 is located in the transmission slot 331. The top of the fixed cone 1 is provided with a guide post 11, and the pressure plate 31 is provided with a connecting hole 32 that matches the guide post 11. The guide post 11 passes through the connecting hole 32 and is connected to the top block 4. The bottom of the top block 4 is provided with a slot 41 for placing a prying tool to pry up the top block 4. When the anti-detachment part 2 is put into the installation slot 12, the pressure plate 31 separates from the top block 4.

[0029] Specifically, the top of the anti-detachment block 21 has an arc-shaped structure and matches the top of the mounting groove 12 (e.g., Figure 8As shown, after the anti-detachment block 21 rotates out of the mounting groove 12, it can still cover the mounting groove 12 to prevent a large amount of soil from entering the mounting groove 12 and the interior of the fixing cone 1, thus affecting the return of the anti-detachment block 21.

[0030] Specifically, the top of the anti-detachment block 21 is provided with several grooves 23. The grooves 23 are located in the area near the outer side of the top of the anti-detachment block 21. The grooves 23 increase the frictional resistance at the top of the anti-detachment block 21, which is beneficial to improving the anti-detachment effect.

[0031] like Figure 1 As shown, the top block 4 is provided with a pry plate 43. The thickness of the pry plate 43 is less than the height of the slot 41. When removing the fixing device, the pry plate 43 on another fixing device can be used to pry the slot 41 to press the plate 31. There is no need to carry other tools to pry and separate the plate 31 and the top block 4, which is convenient to use.

[0032] Specifically, the top block 4 has a threaded hole 42, and the guide post 11 has a through hole 13 that matches the threaded hole 42. The top block 4 is sleeved on the guide post 11, and screws 44 are inserted into the threaded hole 42 and the through hole 13. The top block 4 is easy to disassemble, and it is convenient to disassemble and repair after the pry plate 43 is deformed.

[0033] In use, the shade net is first laid in the target area. Then, by tapping the top block 4, the fixing cone 1 can be driven into the shade net and embedded into the soil. During the process of driving the fixing cone 1 into the ground, the pressure plate 31 does not contact other objects, thus keeping the anti-detachment block 21 in the mounting groove 12 (as shown in 6-8). When the pressure plate 31 can no longer descend after contacting the shade net with the ground, continuing to tap the top block 4 downwards will cause the ground surface to push the pressure plate 31 and the top block 4 together. This will cause the transmission slot 331 on the linkage rod 3 to drive the transmission block 22 to rotate, causing the anti-detachment block 21 to extend out of the mounting groove 12 and lock into the soil, thus preventing the fixing cone 1 from detaching from the soil. When it is necessary to remove the fixing cone 1, the pry plate 43 on another free fixing device is inserted into the slot 41, and the top block 4 is pried apart using the pressure plate 31 as a fulcrum. This causes the fixing cone 1 to rise and the anti-detachment block 21 to rotate back into the mounting groove 12, making it easier to pull the fixing device out of the ground later.

[0034] The foregoing has provided a detailed description of a forestry shade net fixing device provided by this utility model. The specific embodiments are described only to aid in understanding the method and core concept of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
