Description

Technical Field

[0001] This utility model relates to the field of forestry protection technology, specifically to a nylon net for sand prevention and control. Background Technology

[0002] Soil desertification is defined as land degradation in arid, semi-arid, and sub-humid arid regions caused by a variety of factors, including climate change and human activities. To combat soil desertification, people plant drought-resistant trees such as Haloxylon ammodendron and Populus euphratica in soils with high sand content to prevent wind erosion and fix sand. However, when the seedlings are first planted, because their roots are not deep, they are easily killed if strong winds blow away the sand around their roots. Therefore, people often use sand-fixing nets to protect the seedlings. The sand-fixing nets are removed after the seedlings mature and used to protect new seedlings.

[0003] The existing sand control nylon netting has a relatively simple internal structure, mostly consisting of a single mesh. During later use, operators need to use fixing rods to secure the mesh, which is cumbersome and affects the convenience of later operation. Furthermore, the sand control nylon netting requires operators to cut it according to actual needs, and the cut nylon netting is often not easy to recycle, increasing the consumption of nylon mesh. Utility Model Content

[0004] The purpose of this utility model is to provide a sand-control nylon net, which solves the problem that in the actual operation of existing sand-control nylon nets, operators still need to use external fixing rods to install and fix the nylon net. Furthermore, the nylon net still needs to be cut according to actual operation needs during later use. Cut nylon nets are not only not easy to recycle, but also increase the consumption of nylon nets.

[0005] To achieve the above objectives, a sand-control nylon net is provided, comprising a first winding drum, a second winding drum, a third winding drum, and a fourth winding drum. A fourth winding shaft is rotatably connected to the middle position inside the first winding drum. The first nylon net is wound around the outside of the fourth winding shaft, and one end of the first nylon net extends to the outside of the first winding drum. A slide rail is provided at the middle position on the side of the first winding drum away from the first nylon net. An L-shaped locking rod extending to the outside is slidably provided inside and at the bottom of the slide rail. A spring connected to the L-shaped locking rod is provided at the middle position inside the slide rail.

[0006] According to the sand control nylon net, a winding shaft three is rotatably installed at the middle position inside the winding drum two. A nylon net two that matches the winding shaft three is wound around the outside of the winding shaft three, and one end of the nylon net two extends to the outside of the winding drum two. The side of the winding drum two away from the nylon net two is connected to the side of the nylon net one away from the winding drum one.

[0007] According to the aforementioned sand-control nylon net, a take-up shaft is rotatably connected at the middle position inside the take-up drum three. A nylon net three that matches the take-up shaft one is wound around the outside of the take-up shaft one, and one end of the nylon net three extends to the outside of the take-up drum three. The side of the take-up drum three away from the nylon net three is connected to the side of the nylon net two away from the take-up drum two.

[0008] According to the aforementioned sand-control nylon net, a second winding shaft is rotatably connected to the middle position inside the fourth winding drum. A fourth nylon net is wound around the outside of the second winding shaft, and one end of the fourth nylon net extends to the outside of the fourth winding drum. A connecting rod is installed at the end of the fourth nylon net away from the fourth winding drum. A slot is provided at the middle position of the side of the connecting rod away from the fourth nylon net, and the slot cooperates with an L-shaped locking rod. The side of the fourth winding drum away from the fourth nylon net is connected to the end of the third nylon net away from the third winding drum.

[0009] According to the aforementioned sand-control nylon netting, the bottom of each of the first, second, third, and fourth winding drums is provided with a counterweight rod, and the counterweight rod is fixedly connected to the first, second, third, and fourth winding drums.

[0010] According to the aforementioned sand-control nylon net, the top and bottom of the four winding shafts, three winding shafts, one winding shaft, and two winding shafts are all provided with coil springs, and the coil springs are respectively connected to the top and bottom of the interior of the one winding drum, two winding drums, three winding drums, and four winding drums.

[0011] Compared with the prior art, the beneficial effects of this utility model are: through the structural design of winding drum one, winding drum two, winding drum three, winding drum four, nylon net one, nylon net two, nylon net three, nylon net four and counterweight rod, the integrated structural design of the sand control nylon net can be realized, and during later installation and use, there is no need for operators to use external fixing rods, which increases the practicality and convenience of later installation and use of the nylon net;

[0012] Meanwhile, the structural design of the four winding shafts, three winding shafts, one winding shaft, and two winding shafts allows for the winding of nylon mesh one, nylon mesh two, nylon mesh three, and nylon mesh four, respectively. This facilitates the operator's ability to adjust the area enclosed by the nylon mesh during later use, and eliminates the need for the operator to cut the nylon mesh. This also makes it easier to recycle the nylon mesh later, reducing consumption.

[0013] Finally, the structural design of the connecting rod, slot, slide rail, spring, and L-shaped clamp makes it easy for operators to fix the beginning and end of the nylon mesh later, increasing the convenience and flexibility of the connection and further enhancing the integrated performance of the nylon mesh operation. Operators no longer need to carry external tightening tools for the nylon mesh connection.

[0023] Please see Figure 1-5This utility model provides a technical solution: a sand-control nylon net, including a first winding drum 1, a second winding drum 3, a third winding drum 5, and a fourth winding drum 8. A fourth winding shaft 15 is rotatably connected to the middle position inside the first winding drum 1. A nylon net 2 is wound around the outside of the fourth winding shaft 15, with one end of the nylon net 2 extending to the outside of the first winding drum 1. A slide rail 16 is provided at the middle position on the side of the first winding drum 1 away from the nylon net 2. L-shaped locking rods 18 extending to the outside are slidably provided inside and at the bottom of the slide rail 16. A spring 17 connected to the L-shaped locking rods 18 is provided at the middle position inside the slide rail 16. A take-up shaft 13 is rotatably mounted at the center of the inner part of the take-up drum 3. A nylon mesh 2 4 is wound around the outside of the take-up shaft 3 13, and one end of the nylon mesh 2 4 extends to the outside of the take-up drum 3. The side of the take-up drum 3 away from the nylon mesh 2 4 is connected to the end of the nylon mesh 2 away from the take-up drum 1. A take-up shaft 6 is rotatably connected at the center of the inner part of the take-up drum 3 5. A nylon mesh 3 7 is wound around the outside of the take-up shaft 6, and one end of the nylon mesh 3 7 extends to the outside of the take-up drum 3 5. The side of the take-up drum 3 5 away from the nylon mesh 3 7 is connected to the end of the nylon mesh 2 4 away from the take-up drum 3. A take-up shaft 2 9 is rotatably connected at the middle position inside the take-up drum 4 8. A nylon mesh 4 10 is wound around the outside of the take-up shaft 2 9 to cooperate with it, and one end of the nylon mesh 4 10 extends to the outside of the take-up drum 4 8. A connecting rod 12 is installed at the end of the nylon mesh 4 10 away from the take-up drum 4 8. A slot 11 is opened at the middle position of the side of the connecting rod 12 away from the nylon mesh 4 10, and the slot 11 cooperates with the L-shaped locking rod 18. The side of the take-up drum 4 8 away from the nylon mesh 4 10 is connected to the end of the nylon mesh 3 7 away from the take-up drum 3 5. The take-up drum 1, take-up drum 2, take-up drum 3, take-up drum 5, take-up drum 4 8 and nylon mesh 1 2. The connection design of nylon mesh 2 (4), nylon mesh 3 (7), and nylon mesh 4 (10) facilitates the integrated connection of the nylon mesh, enabling direct and secure installation during later use without the need for external fixing rods. Finally, the winding design of the reel 4 (15), reel 3 (13), reel 1 (6), and reel 2 (9) with nylon mesh 1 (2), nylon mesh 2 (4), nylon mesh 3 (7), and nylon mesh 4 (10) allows for easy adjustment of the area enclosed by the nylon mesh, facilitating recycling without the need for cutting, thus increasing the practicality and flexibility of the nylon mesh for later use.

[0024] The bottom of take-up drum 1, take-up drum 2, take-up drum 3, and take-up drum 4 are all equipped with counterweight rods 14, and the counterweight rods 14 are fixedly connected to the bottom of take-up drum 1, take-up drum 2, take-up drum 3, and take-up drum 4. The design of the counterweight rods 14 facilitates the later installation and fixing of take-up drum 1, take-up drum 2, take-up drum 3, and take-up drum 4, allowing the counterweight rods 14 to be buried in the sand pit to improve installation stability. The take-up shaft 4 15... The top and bottom of the three reel 13, the first reel 6, and the second reel 9 are all equipped with coil springs, and the coil springs are respectively connected to the top and bottom of the inside of the first reel 1, the second reel 3, the third reel 5, and the fourth reel 8. Through the design of the coil springs, the automatic winding function of the fourth reel 15, the third reel 13, the first reel 6, and the second reel 9 can be easily realized, without the need for manual winding by the operator, which increases the convenience and flexibility of the nylon net for later removal and use.

[0025] Working principle: During use, the operator can directly use take-up drums 1, 3, 5, and 8 to drive the counterweight rod 14 into the pre-dug sand pit, thus fixing and installing take-up drums 1, 2, 3, 5, and 8. This structural design achieves an integrated structure between the nylon net and the fixing rod, eliminating the need for external fixing rods for later installation. Simultaneously, take-up drum 1 and the above components are placed... After completion, the placement of the second take-up drum 3 can pull the nylon net 2 to move inside the first take-up drum 1, thereby rotating the fourth take-up shaft 15 to release the nylon net 2. The removal of the nylon net 2 can achieve the function of sand prevention and control. Furthermore, the elongation design of the nylon net 2 can achieve the function of adjusting the distance between the first take-up drum 1 and the second take-up drum 3, which can facilitate the subsequent implementation of sand and soil stabilization design for different areas, allowing operators to adjust according to actual operational needs.

[0026] Simultaneously, taking-up drums 3 (5) and 4 (8) share the same structural design as taking-up drums 1 (1) and 2 (3). The movement of taking-up drum 3 (5) stretches the nylon mesh 2 (4) inside taking-up drum 2 (3), causing the nylon mesh 2 (4) to rotate and unwind the taking-up shaft 3 (13). Moving taking-up drum 4 (8) removes the nylon mesh 3 (7) from inside taking-up drum 3 (5), causing the nylon mesh 3 (7) to rotate the taking-up shaft 1 (6). The taking-up shaft 1 (6) then unwinds the nylon mesh 3 (7). Finally, pulling connecting rod 12 moves the nylon mesh 4 (10) out of taking-up drum 4 (8), causing the nylon mesh 4 (10) to rotate the taking-up shaft 2 (9) to unwind it. Figure 2 The diagram illustrates the enclosure of sandy soil.

[0027] When the connecting rod 12 is pulled to approach the winding drum 1, the operator can directly press the L-shaped locking rod 18 to move it closer inside the slide rail 16, thereby compressing the spring 17. Then, the connecting rod 12 drives the locking groove 11 to engage with the outside of the L-shaped locking rod 18. Finally, the elastic restoring force of the spring 17 can drive the L-shaped locking rod 18 to expand back, thereby achieving the engagement connection between the L-shaped locking rod 18 and the locking groove 11. This realizes the connection function of the nylon net for later installation, increases the integrated performance of the nylon net for later operation, and the structure is simple, reasonable and suitable for promotion. Finally, through the above operation design, it is also convenient for the operator to recycle the nylon net later, and the operator does not need to cut the nylon net.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
