Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, specifically to a frame connection structure for a wind-resistant greenhouse for highland summer vegetables. Background Technology

[0002] Highland summer vegetables refer to vegetables grown in high-altitude areas of my country, typically above 1500 meters, taking advantage of the cool summer climate. They are diverse in variety, but high-altitude areas have low temperatures. Even in summer, nighttime temperatures can drop below 10°C, and frost and cold waves are common in spring and autumn. Greenhouses, through the heat preservation effect of the thin-film glass, can keep the temperature inside the greenhouse 5-10°C higher than the outside temperature, effectively preventing seedlings from freezing and mature plants from stunting, thus ensuring the normal growth cycle of crops.

[0003] Traditional greenhouse frame connection structures, such as welding, bolted connections, and simple sleeve connections, typically have fixed node angles. This makes it impossible to adjust the connection angles according to the sloping terrain of highland terraces and slopes, easily leading to uneven greenhouse construction and uneven stress. At the same time, they cannot adapt to greenhouse arch designs with different curvatures; a single frame can only meet the needs of a single greenhouse type, lacking flexibility. Furthermore, the fixed lateral spacing between arches cannot be adjusted according to the agronomical requirements of different varieties of highland summer vegetables. Growers need to build or replace frames separately for different varieties, increasing equipment investment and labor costs, thus presenting certain limitations. Utility Model Content

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1: Please refer to Figure 1 - Figure 5 This utility model provides a technical solution: a wind-resistant greenhouse frame connection structure for highland summer vegetables, including two fixed plates 1, with multiple frame structures 2 in the middle of the two fixed plates 1. Each frame structure 2 includes a connecting rod 21, with a longitudinal support rod 22 fixedly installed at the lower end of the connecting rod 21, and a base plate 23 fixedly installed at the lower end of the longitudinal support rod 22. Fixed outer cylinders 25 are fixedly installed on both sides of the middle of the connecting rod 21. A threaded rod 31 is threadedly connected to one end of the fixed outer cylinder 25, and a chuck 32 is fixedly installed at one end of the threaded rod 31. A gear plate 33 is slidably engaged in the middle of the fixed outer cylinder 25, with a groove 34 in the middle of one end of the gear plate 33, and a semi-sealed part in the other end of the fixed outer cylinder 25. The semi-enclosed rotating groove 26 is rotatably engaged with the rotating cylinder 27 in the middle. One end of the rotating cylinder 27 is fixedly installed with a gear plate 28. A U-shaped plate 29 is fixedly installed on one side of the rotating cylinder 27. An arc-shaped top rod 17 is provided in the middle of the U-shaped plate 29. A top screw hole 18 is opened in the middle of the other end of the arc-shaped top rod 17. A second top screw hole 30 is opened through the middle of the U-shaped plate 29. The second top screw hole 30 and the first top screw hole 18 are connected and the second top screw 19 is threaded in the middle. Multiple limiting holes 24 are evenly opened around the middle of the base 23. The U-shaped plate 29 is rotatably engaged with the middle of the semi-enclosed rotating groove 26. The chuck 32 is rotatably engaged with the middle of the slot 34. The gear plate 23 and the gear plate 28 mesh.

[0017] In this embodiment, during use, the angle can be adjusted according to the terrain or force requirements. During adjustment, rotating the threaded rod 31 drives the chuck 32 to move away from the gear disc 33. Since the threaded rod 31 is engaged with the chuck 32 at its end and the groove 34 of the gear disc 33, it will simultaneously drive the gear disc 33 to slide axially within the fixed outer cylinder 25, disengaging from the gear disc 28. At this time, the rotating cylinder 27 can rotate freely. Due to the limiting effect of the semi-enclosed rotating groove 26, the U-shaped plate 29 can only rotate along the set trajectory. The user can adjust the angle according to the design arc of the greenhouse frame. Adjusting the U-shaped plate 29 to a preset angle, such as the bending angle of the top arch or the slope of the terrain, ensures that the arc-shaped top rod 17 can form a continuous and stable greenhouse arch. Then, rotate the threaded rod 31 in the opposite direction, causing the second toothed disc 33 to slide along the fixed outer cylinder 25 until it is fully engaged with the first toothed disc 28. At this time, the engagement of the two toothed discs can prevent the rotating cylinder 27 from rotating, thus achieving angle locking and preventing angle deviation under wind. At the same time, the threaded connection of the threaded rod 31 has self-locking properties, which, together with the mechanical positioning of the toothed disc engagement, forms a dual system of thread locking and toothed disc anti-rotation. To prevent loosening of connections due to strong winds at high altitudes, the arc-shaped top rod 17 is threaded onto the U-shaped plate 29 via a top screw 19 passing through a top screw hole 30 and a top screw hole 18, ensuring a stable connection between the arch rod and the connecting mechanism. Repeating the above installation steps completes the connection of all the frame structures 2. The fixing plate 1 integrates the nodes, allowing the arc-shaped top rod 17 to form a continuous greenhouse arch frame. The connecting rod 21 and longitudinal support rod 22 form a longitudinal support system. The entire frame is fixed to the ground with anchor bolts through the limiting holes 24 of the base plate 23, improving pull-out resistance. When encountering strong winds at high altitudes, the wind load is transmitted to the U-shaped plate 29 through the arc-shaped top rod 17, and then to the fixed outer cylinder 25 and connecting rod 21 through the rotating cylinder 27 and the toothed disc meshing structure. Finally, it is transmitted to the ground through the longitudinal support rod 22 and the chassis 23. This not only solves the problem of the fixed connection angle of traditional greenhouse frames, which cannot adapt to complex terrain or diverse arch frame designs, but also strengthens the wind and vibration resistance of the connection points through the toothed disc meshing and threaded double fixing structure. It is precisely adapted to the environmental characteristics of strong winds and large temperature differences in high-altitude areas, ensuring the overall stability of the greenhouse frame.

[0018] Example 2: As Figure 1 - Figure 3 As shown, a sliding groove 12 is provided on one side of the middle of the two fixed plates 1. Multiple sliders 13 are evenly slidably engaged in the middle of the two sliding grooves 12. The upper ends of the sliders 13 are fixedly connected to one end of the arc-shaped top rod 17. Multiple ground nails 11 are evenly provided on the other side of the middle of the two fixed plates 1. Multiple bottom screw holes 14 are evenly provided on the upper part of one side of the middle of the fixed plate 1. A bottom screw hole 2 15 is provided on one side of the multiple sliders 13. The bottom screw holes 14 and the bottom screw holes 2 15 are connected and a screw 16 is threaded in the middle.

[0019] In this embodiment, the arc-shaped top rod 17 is slidably engaged with the groove 12 of the fixed plate 1 via the slider 13, forming a "multi-point support and overall linkage structure". When the plateau wind acts on the shed, the wind load can be evenly transmitted to the fixed plate 1 through multiple sliders 13, and then transmitted to the ground through the ground nails 11, avoiding stress concentration caused by traditional single-point connection and significantly improving the overall wind resistance and deformation resistance of the shed. The slider 13 is double fixed by being engaged with the groove 12 and locked with screw 16, which not only restricts the lateral displacement of the arc-shaped top rod 17, but also avoids loosening caused by wind vibration through the self-locking of the thread. At the same time, the ground nails 11 can enhance the anchoring force between the fixed plate 1 and the ground, further improving the shed's pull-out resistance and overturning resistance, effectively resisting plateau gusts. After loosening the screw 16, the slider 13 can slide freely along the groove 12, driving the arc-shaped top rod 17 to adjust the lateral spacing, so that it can adapt to the planting needs of different varieties of plateau summer vegetables without replacing the main frame.

[0020] Working principle: like Figure 1 - Figure 5 As shown, during use, rotating the threaded rod 31 drives the chuck 32 at the end to move away from the gear disc 33. Since the chuck 32 and the groove 34 of the gear disc 33 rotate and engage, the gear disc 33 will be simultaneously pulled to slide axially within the fixed outer cylinder 25, eventually completely disengaging from the gear disc 28. At this point, the rotating cylinder 27 loses the constraint of the gear disc and can rotate freely. Then, using the rotating cylinder 27 as the axis of rotation, the U-shaped plate 29 fixedly connected to it is rotated. The semi-enclosed rotating groove 26 will limit the rotation of the rotating cylinder 27, ensuring that the U-shaped plate 29 rotates only along the set trajectory and avoids deviation. Users can adjust the U-shaped plate 29 to a preset angle according to the slope of the plateau terraces or slopes, or the design curvature of the greenhouse roof arch, to ensure that the curved top rod 17 can be spliced ​​to form a continuous and flat greenhouse arch. Then, the threaded rod 31 is rotated in the reverse direction, pushing the chuck 32 to re-engage in the slot 34 of the gear disc 33. Simultaneously, the gear disc 33 slides along the fixed outer cylinder 25 until it fully engages with the gear disc 28. The engagement structure of the gear disc forms a mechanical anti-rotation mechanism, completely preventing the rotating cylinder 27 from rotating and avoiding angular deviation under the influence of high-altitude winds. Because the threaded connection of the threaded rod 31 has a self-locking characteristic, combined with the mechanical positioning of the gear disc engagement, a dual fixing structure of threaded locking and gear disc anti-rotation is formed, effectively resisting connection loosening caused by high-altitude wind vibrations. Finally, the arc-shaped top rod 17 is fitted against the U-shaped plate 29, and the top screw 19 passes through the top screw hole 30 and the top screw hole 18 to achieve threaded fixation between the arch rod and the connecting mechanism, ensuring the stability of the arch rod and the node connection and preventing vibration-induced detachment.

[0021] Repeat the above steps until all the skeleton structures 2 are connected; then integrate the connecting nodes through the fixing plate 1, so that the arc-shaped top rods 17 are spliced ​​to form a continuous and complete greenhouse arch frame. The connecting rods 21 and the longitudinal support rods 22 form a longitudinal support system, forming an overall skeleton frame. Then, through the limiting holes 24 around the base 23, use anchor bolts to fix the skeleton to the ground to improve the overall pull-out resistance; at the same time, the ground nails 11 on one side of the fixing plate 1 are inserted into the soil to enhance the anchoring force between the fixing plate 1 and the ground, providing double protection against the risk of upward lifting and overturning by the high-altitude gusts. When encountering high-altitude winds, part of the wind load will be transmitted through the arc-shaped top rods 17, first through the U-shaped plate 29, the rotating cylinder 27, and the toothed disc meshing structure to the fixed outer cylinder 25 and the connecting rods 21, and finally through the longitudinal support rods 22 and the base 23 to the ground; another part will be evenly distributed to the fixing plate 1 through the slider 13, and then transmitted to the ground through the ground nails 11. The dual load transfer path avoids local stress concentration, and with the locking and fixing of each node, the core functions of wind resistance and deformation resistance of the canopy are achieved.

[0022] Users can adjust the spacing according to the different planting needs of different varieties of highland summer vegetables, such as widening the spacing for tall crops and narrowing the spacing for densely planted leafy vegetables. Simply loosen screw 16 first, and slider 13 can slide freely along the groove 12 of the fixing plate 1. Since slider 13 is fixedly connected to the arc-shaped top rod 17, sliding slider 13 can drive the arc-shaped top rod 17 to adjust the lateral spacing. There is no need to replace the main frame. After adjusting the arc-shaped top rod 17 to the appropriate spacing, align the bottom screw hole 14 and bottom screw hole 25, and tighten screw 16 to achieve fixation. The device achieves angle adjustment through gear plate meshing and threaded locking, and spacing adjustment through the groove 12, slider 13, and threaded fixing. Finally, it forms a complete system with angle adapted to the terrain, spacing adapted to planting, multi-point load distribution, and wind resistance. It not only solves the pain points of fixed connection angle or spacing and poor adaptability of traditional greenhouse frames, but also specifically strengthens the structural stability under strong winds and complex terrain in highlands, meeting the planting needs of highland summer vegetable greenhouses.
