Description

Technical Field

[0001] This utility model relates to the field of windbreak technology, specifically to an adjustable-height windbreak for high-altitude vegetables. Background Technology

[0002] Windbreaks are windproof and heat-insulating barriers erected in nurseries or cultivated areas during winter. They are simple covering facilities in the field of agricultural meteorology. In high-altitude areas where winter winds are strong, windbreaks improve microclimate conditions by reducing wind speed, increasing ground and air temperature, and reducing the risk of plant frost damage. Windbreaks can reduce wind speed within the protected area by 10%-50%, and in severe cold seasons, can raise the surface temperature by 6°C compared to open ground, and advance soil thawing by about 20 days. They must be installed perpendicular to the monsoon winds. After installation, they should be immediately irrigated to stabilize soil temperature, and after removal, they should be irrigated again to promote plant recovery. This facility is widely used for overwintering seedlings, early spring vegetable planting, increasing cotton yields, and can increase snowmelt storage to alleviate spring drought.

[0003] Traditional vegetable windbreaks have relatively fixed specifications and dimensions, making it difficult to adjust their height according to the actual use of the vegetable field. Since windbreaks are only used in the cold winter, they are often reused. However, when different types of vegetables are protected from the wind, the windbreaks become less effective. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable-height windbreak for high-altitude vegetables, in order to solve the problem mentioned in the background art that traditional vegetable windbreaks are difficult to adjust in height according to the actual use of the vegetable field, and that the windbreak's wind protection effect is reduced when different types of vegetables are protected from the wind.

[0005] To achieve the above objectives, this utility model provides an adjustable-height windbreak for high-altitude vegetables, comprising a first U-shaped frame, a second U-shaped frame above the first U-shaped frame, connecting rods fixedly mounted on both bottom ends of the second U-shaped frame, slots adapted to the connecting rods on both top ends of the first U-shaped frame, a first insert post penetrating through the upper outer wall of the first U-shaped frame, multiple first insertion holes adapted to the first insert post on the surface of the connecting rod, a first end block fixedly mounted on the end of the first insert post away from the connecting rod, a first spring sleeved on the outer side of the first insert post, the two ends of the first spring being fixed to the first end block and the first U-shaped frame respectively, windproof cloth being provided on the inner sides of the first U-shaped frame and the second U-shaped frame, a connecting block being fixedly mounted on the outer wall of the second U-shaped frame, a connecting groove being provided on the side wall of the second U-shaped frame away from the connecting block, and a fixing component connected to the connecting block being provided on the side wall of the second U-shaped frame.

[0006] By adopting the above scheme, pulling the first end block outward causes the first insertion post to move out of the first insertion hole. Adjusting the height of the second U-shaped frame, the first insertion post is inserted into a first insertion hole by the restoring force of the first spring. This facilitates wind protection for different types of vegetables and effectively ensures the wind protection effect of the windproof cloth.

[0007] As a further improvement to this technical solution, the fixing component includes a second insert post, which is disposed through the side wall of the second U-shaped frame. The surface of the connecting block is provided with a second insertion hole that is adapted to the second insert post. A second end block is fixedly disposed at the end of the second insert post away from the connecting groove. A second spring is sleeved on the outside of the second insert post, and the two ends of the second spring are respectively fixed to the second end block and the second U-shaped frame.

[0008] By adopting the above solution, two second U-shaped frames are fixed with fixing components, making it convenient to splice multiple second U-shaped frames together.

[0009] As a further improvement to this technical solution, the surface of the second insertion post is provided with an oblique opening, which is used to contact the connecting block and push the second insertion post to move outward.

[0010] By adopting the above solution, the beveled opening facilitates the insertion of the connecting block into the connecting groove.

[0011] As a further improvement to this technical solution, the upper end of the windproof cloth is fixed to the inner wall of the second U-shaped frame, the bottom end of the windproof cloth is fixed to the inner wall of the first U-shaped frame, and pleats are provided in the middle of the windproof cloth.

[0012] By adopting the above scheme, the windproof fabric is stretched or folded by moving the pleats, thereby adapting the windproof fabric to the height position of the second U-shaped frame.

[0013] As a further improvement to this technical solution, two main insertion rods are fixedly installed at the bottom of the first U-shaped frame, and the two main insertion rods are respectively located on both sides of the bottom of the first U-shaped frame.

[0014] By adopting the above scheme, the first U-shaped frame and the second U-shaped frame are installed by inserting two main poles into the ground.

[0015] As a further improvement to this technical solution, the first U-shaped frame sidewall is provided with four sets of support components, each of the four sets of support components including a support rod. The top end of the support rod is hinged to the sidewall of the first U-shaped frame, and the bottom end of the support rod is hinged to an auxiliary insertion rod.

[0016] By adopting the above scheme, the stability of the first U-shaped frame is improved by inserting four auxiliary rods into the ground and then by using four support rods.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting up a second U-shaped frame, pulling the first end block outwards moves the first insertion post, causing the first insertion post to move out of the first insertion hole. Adjusting the height of the second U-shaped frame, the first insertion post is inserted into a first insertion hole by the restoring force of the first spring. The second U-shaped frame extends or folds the pleats through the windproof cloth, thereby adapting the windproof cloth to the height of the second U-shaped frame, which facilitates wind protection for different types of vegetables and effectively ensures the windproof protection effect of the windproof cloth.

[0018] 2. By setting up fixing components, two second U-shaped frames can be fixed together, and so on, multiple second U-shaped frames can be spliced ​​together to form a windbreak, which protects the vegetables from the wind. Similarly, it is also convenient to disassemble the windbreak into small parts for easy transportation and storage. Attached Figure Description

[0023] Please see Figures 1-2 As shown, this utility model provides an adjustable-height windbreak for high-altitude vegetables, including a first U-shaped frame 1, a second U-shaped frame 2 above the first U-shaped frame 1, with the openings of the first U-shaped frame 1 and the second U-shaped frame 2 facing each other. Connecting rods 3 are fixedly installed at the bottom ends of both sides of the second U-shaped frame 2. Slots 4, adapted to the connecting rods 3, are opened at the top ends of both sides of the first U-shaped frame 1. The first U-shaped frame 1 and the second U-shaped frame 2 are connected by inserting the two connecting rods 3 into the two slots 4 respectively. A first insert post 5 is provided through the upper outer wall of the first U-shaped frame 1. Multiple first insertion holes 8, adapted to the first insert post 5, are opened on the surface of the connecting rods 3. A first end block 6 is fixedly installed at the end of the first insert post 5 away from the connecting rod 3. A first spring 7 is sleeved on the outside of the first insert post 5. The two ends of the first spring 7 are fixed to the first end block 6 and the first U-shaped frame 1 respectively, and can be pulled outwards. The first end block 6 moves the first insertion post 5, causing it to move out of the first insertion hole 8. This allows the second U-shaped frame 2 to move up and down, adjusting its height. The restoring force of the first spring 7 causes the first insertion post 5 to be inserted into a first insertion hole 8, fixing the second U-shaped frame 2 in place. Windproof cloth 9 is provided on the inner side of the first U-shaped frame 1 and the second U-shaped frame 2. The upper end of the windproof cloth 9 is fixed to the inner wall of the second U-shaped frame 2, and the lower end is fixed to the inner wall of the first U-shaped frame 1. A pleat 10 is provided in the middle of the windproof cloth 9. When the second U-shaped frame 2 moves up and down for adjustment, the second U-shaped frame 2 extends or folds the pleat 10 through the windproof cloth 9, thereby adapting the windproof cloth 9 to the height position of the second U-shaped frame 2. This facilitates wind protection for different types of vegetables and effectively ensures the windproof protection effect of the windproof cloth 9.

[0024] Please see Figure 1As shown, two main insertion rods 18 are fixedly installed at the bottom of the first U-shaped frame 1. The two main insertion rods 18 are located on both sides of the bottom of the first U-shaped frame 1. By inserting the two main insertion rods 18 into the ground, the first U-shaped frame 1 and the second U-shaped frame 2 are installed. The side wall of the first U-shaped frame 1 is provided with four sets of support components. Each set of support components includes a support rod 19. The top of the support rod 19 is hinged to the side wall of the first U-shaped frame 1, and the bottom of the support rod 19 is hinged to an auxiliary insertion rod 20. The four support rods 19 are spread out to both sides, so that the four auxiliary insertion rods 20 are inserted into the ground, thereby improving the support stability of the first U-shaped frame 1 through the four support rods 19.

[0025] Please see Figure 1 and Figure 3 As shown, a connecting block 11 is fixedly installed on the outer wall of the second U-shaped frame 2. A connecting groove 12 is opened on the side wall of the second U-shaped frame 2 away from the connecting block 11. A fixing component connected to the connecting block 11 is provided on the side wall of the second U-shaped frame 2. When splicing multiple second U-shaped frames 2, the connecting block 11 is inserted into the connecting groove 12 of the previous second U-shaped frame 2 from top to bottom. Then, the two main inserts 18 at the bottom of the first U-shaped frame 1 are inserted into the ground, and the two second U-shaped frames 2 are fixed by the fixing component. This process is repeated to facilitate the splicing of multiple second U-shaped frames 2, thereby forming a windbreak with multiple windproof cloths 9 to protect the vegetables from the wind. Similarly, it is also convenient to disassemble the windbreak into smaller parts for easy transportation and storage. The component includes a second insert post 13, which is disposed through the side wall of the second U-shaped frame 2. A second insertion hole 14 adapted to the second insert post 13 is opened on the surface of the connecting block 11. A second end block 15 is fixedly disposed at the end of the second insert post 13 away from the connecting groove 12. A second spring 16 is sleeved on the outside of the second insert post 13. The two ends of the second spring 16 are respectively fixed to the second end block 15 and the second U-shaped frame 2. A bevel 17 is opened on the surface of the second insert post 13. The bevel 17 is used to contact the connecting block 11 and push the second insert post 13 to move outward. The restoring force of the second spring 16 drives the second insert post 13 to be inserted into the second insertion hole 14, thereby fixing the two second U-shaped frames 2. The bevel 17 facilitates the insertion of the connecting block 11 into the connecting groove 12.

[0026] The specific working principle of this utility model is as follows: Pulling the first end block 6 outward causes the first insertion post 5 to move, so that the first insertion post 5 moves out of the first insertion hole 8, and the second U-shaped frame 2 can be moved up and down to adjust the height position of the second U-shaped frame 2. Through the restoring force of the first spring 7, the first insertion post 5 is inserted into a first insertion hole 8 to fix the second U-shaped frame 2. When the second U-shaped frame 2 moves up and down for adjustment, the second U-shaped frame 2 causes the pleats 10 to extend or fold through the windproof cloth 9, so that the windproof cloth 9 adapts to the height position of the second U-shaped frame 2, which facilitates wind protection for different kinds of vegetables and effectively ensures the windproof protection effect of the windproof cloth 9. The two second U-shaped frames 2 are fixed by the fixing components, and so on, so that multiple second U-shaped frames 2 can be spliced ​​together, so that multiple windproof cloths 9 form a windbreak to protect the vegetables from the wind.
