Description

Technical Field

[0001] This utility model relates to the field of isolation net technology, and in particular to an insect-proof isolation net for green prevention and control of highland vegetables. Background Technology

[0002] Vegetables are an essential part of people's daily diet, providing the human body with a variety of essential vitamins and minerals. When growing vegetables, it is necessary to take measures to prevent pests.

[0003] For example, the Chinese patent with authorization announcement number CN217241780U discloses an insect-proof isolation net for green prevention and control of high-altitude vegetables. Its working principle is: "By setting up a magnet, a moving ring, and an isolation net, when personnel need to enter the vegetable planting area, they can make the moving ring detach from the magnet, thereby making the height of the isolation net easy to adjust so that personnel can cross the isolation net to enter the vegetable planting area." In actual use, when personnel need to enter the vegetable planting area, they can manually apply a certain force to the moving ring, thereby making the moving ring detach from the magnet, and thus making the height of the isolation net easy to adjust so that personnel can cross the isolation net to enter the vegetable planting area. If the moving ring is positioned too high, it is not suitable for people of shorter stature. Conversely, if the moving ring is positioned too low, the height of the isolation net is also relatively low, and it will not play a certain isolation role. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: A pest-proof isolation net for green pest control of highland vegetables includes a first mounting post and a second mounting post located at the right end of the first mounting post. The lower ends of the first and second mounting posts are provided with mounting holes. The ends of the first and second mounting posts that are close to each other are provided with lifting grooves. A roll unwinder is fixedly connected to the lower end face of the inner cavity of the lifting groove. An isolation net is fixedly connected to the outer wall of the roll unwinder. A lifting plate is fixedly connected to the upper end of the isolation net, and the outer wall of the lifting plate is engaged with the upper end of the inner cavity of the lifting groove. A lifting mechanism for adjusting the height of the isolation net is fixedly connected to the upper end face of the lifting plate.

[0005] As an improvement to the above technical solution, a limit rod is installed in the inner cavity of the lifting groove, and the outer wall of the limit rod is movably sleeved with the inner walls at both ends of the lifting plate.

[0006] As an improvement to the above technical solution, the lifting mechanism includes a rotating drum and a rope. The rotating drum is fixedly connected to the front of the second mounting column, the lower end of the rope is fixedly connected to the outer wall of the rotating drum, and the rear end of the rope passes through the upper end of the second mounting column and is fixedly connected to the upper end face of the lifting plate.

[0007] As an improvement to the above technical solution, the lifting mechanism further includes a rotating shaft, the two ends of which are rotatably connected to the upper end of the second mounting column, and the outer wall of the rotating shaft overlaps with the outer wall of the rope.

[0008] As an improvement to the above technical solution, the lifting mechanism further includes a limiting plate, a screw, a first limiting tooth, and a second limiting tooth. The outer wall of the limiting plate is engaged with the inner wall of the front end of the inner cavity of the lifting groove. The outer wall of the front end of the screw is rotatably connected to the inner wall of the second mounting column, and the outer wall of the rear end of the screw is threadedly connected to the inner wall of the limiting plate. A knob is installed at the front end of the screw. The front end of the first limiting tooth is fixedly connected to the rear end face of the limiting plate, and the rear end of the second limiting tooth is fixedly connected to the front end of the lifting plate. The front end of the second limiting tooth is engaged with the rear end of the first limiting tooth.

[0009] The beneficial effects of this utility model are: The lifting mechanism rotates to move the lifting plate up and down inside the lifting trough, thereby adjusting the height of the isolation net. When personnel need to enter the vegetable planting area, the lifting mechanism reverses to move the isolation net downwards, facilitating personnel entry. This ensures both the insect-proof effect of the isolation net and the ease of personnel entry and exit. Attached Figure Description

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0013] Please see Figure 1-6 This utility model provides a technical solution: an insect-proof isolation net for green prevention and control of highland vegetables, including a first mounting post 1 and a second mounting post 2 located at the right end of the first mounting post 1. The lower ends of the first mounting post 1 and the second mounting post 2 are provided with mounting holes. The ends of the first mounting post 1 and the second mounting post 2 that are close to each other are provided with a lifting groove 3. The lower end face of the inner cavity of the lifting groove 3 is fixedly connected to an unwinding device 4. The outer wall of the unwinding device 4 is fixedly connected to an isolation net 5. The upper end of the isolation net 5 is fixedly connected to a lifting plate 6, and the outer wall of the lifting plate 6 is engaged with the upper end of the inner cavity of the lifting groove 3. The upper end face of the lifting plate 6 is fixedly connected to a lifting mechanism 7 for adjusting the height of the isolation net 5.

[0014] The lifting mechanism 7 rotates to move the lifting plate 6 up and down inside the lifting groove 3, thereby adjusting the height of the isolation net 5. When personnel need to enter the vegetable planting area, the lifting mechanism 7 reverses, causing the isolation net 5 to move downwards, facilitating personnel entry. This ensures both the insect-proof effect of the isolation net 5 and convenient access for personnel. Specifically, a limit rod is installed in the inner cavity of the lifting groove 3, and the outer wall of the limit rod is movably connected to the inner walls at both ends of the lifting plate 6.

[0015] The limiting rod allows the lifting plate 6 to move stably downward under the action of the rope 72.

[0016] Specifically, the lifting mechanism 7 includes a rotating drum 71 and a rope 72. The rotating drum 71 is fixedly connected to the front of the second mounting column 2. The lower end of the rope 72 is fixedly connected to the outer wall of the rotating drum 71, and the rear end of the rope 72 passes through the upper end of the second mounting column 2 and is fixedly connected to the upper end face of the lifting plate 6.

[0017] The forward rotation of the drum 71 winds up the rope 72, raising the lifting plate 6 and the isolation net 5, thus achieving the insect-proof effect of the isolation net 5. When personnel need to enter the vegetable planting area, the drum 71 reverses, unwinding the rope 72. The lifting plate 6 and the isolation net 5 then move downwards under gravity, facilitating personnel entry. This system ensures both the insect-proof effect of the isolation net 5 and convenient access for personnel. Specifically, the lifting mechanism 7 also includes a rotating shaft 73, the two ends of which are rotatably connected to the upper end of the second mounting column 2, and the outer wall of the rotating shaft 73 overlaps with the outer wall of the rope 72.

[0018] During the pulling process, rope 72 contacts the outer wall of shaft 73, allowing shaft 73 to rotate relative to rope 72. This relative rotation prevents rope 72 from generating severe friction during movement; instead, it moves on the surface of shaft 73 through rolling friction. The frictional force of rolling friction is much smaller than that of sliding friction, significantly reducing wear on rope 72, extending its service life, lowering equipment maintenance costs and replacement frequency, and ensuring that rope 72 maintains good strength and stability during long-term use, thus ensuring the safe and reliable operation of lifting and lowering the isolation net 5.

[0019] Specifically, the lifting mechanism 7 also includes a limiting plate 74, a screw 75, a first limiting tooth 76, and a second limiting tooth 77. The outer wall of the limiting plate 74 is engaged with the inner wall of the front end of the inner cavity of the lifting groove 3. The outer wall of the front end of the screw 75 is rotatably connected to the inner wall of the second mounting post 2, and the outer wall of the rear end of the screw 75 is threadedly connected to the inner wall of the limiting plate 74. A knob is installed at the front end of the screw 75. The front end of the first limiting tooth 76 is fixedly connected to the rear end face of the limiting plate 74. The rear end of the second limiting tooth 77 is fixedly connected to the front end of the lifting plate 6, and the front end of the second limiting tooth 77 is engaged with the rear end of the first limiting tooth 76.

[0020] like Figure 6 As shown, the rotation of the screw 75 causes the limiting plate 74 to move backward. The backward movement of the limiting plate 74 causes the first limiting tooth 76 to engage with the second limiting tooth 77 installed at the front end of the lifting plate 6, thereby limiting the lifting plate 6 and preventing the lifting plate 6 and the isolation net 5 from moving downward due to gravity when preventing insects, thus ensuring the stability of the isolation net 5 when preventing insects.

[0021] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
