Description

Technical Field

[0001] This utility model relates to the field of agricultural planting protection equipment technology, specifically a cotton seedling heat preservation and frost protection covering device. Background Technology

[0002] Cotton is an important economic crop in my country, and its seedling growth directly determines its subsequent yield and quality. Cotton seedlings are extremely sensitive to environmental temperature, with an optimal growth range of 20-25℃. When the temperature drops below 10℃, the growth rate decreases significantly, and temperatures below 0℃ cause irreversible frost damage, leading to seedling wilting or even death. Spring is a critical period for cotton sowing and seedling cultivation. During this time, northern regions frequently experience late frosts, and southern regions often suffer from late frosts. Low temperatures and frost have become a core bottleneck restricting the survival and robust growth of cotton seedlings, necessitating reliable insulation and frost protection measures.

[0003] Existing methods typically use bamboo poles, thin steel pipes, or wooden strips as the frame for cotton sheds. Arched or ridge-shaped frames are constructed on-site according to the dimensions of the cotton planting beds. Polyethylene or polyvinyl chloride (PVC) film is then covered onto the frame surface, and the edges are secured with ropes or clods of soil to create a closed microclimate. The film's insulating effect reduces heat loss, achieving the purpose of insulation and frost protection. However, the existing frame's uprights, crossbars, and arches are mostly independent straight or curved rods, temporarily connected by binding or splicing. Disassembly requires disassembling all components individually, and the disassembled components are all rigid structures of fixed length, unable to be folded or retracted, significantly increasing the labor intensity of disassembly. Therefore, a cotton seedling insulation and frost protection covering device is needed to address these drawbacks and improve the effectiveness. Utility Model Content

[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] To make the objectives, technical solutions and advantages of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Please see Figure 1-5 As shown, this utility model is a cotton seedling heat preservation and frost protection covering device, comprising: Covering membrane 11; The folding component includes a vertical pole 21, a first supporting half-ring 22, a second supporting half-ring 23, a support block 24, a side plate 25, and a rotating rod 26. The vertical pole 21 is located at the bottom of the inner surface of the covering film 11. The first supporting half-ring 22 is fixed to the top of one side of the vertical pole 21, and the second supporting half-ring 23 is fixed to the top of the other side of the vertical pole 21. The side plate 25 is fixed to the upper and lower parts of one end of the outer surface of the first supporting half-ring 22. The rotating rod 26 is located between the two side plates 25. One side of the support block 24 is fixed to one end of the outer surface of the second supporting half-ring 23, and the other side is rotatably connected to the outer surface of the rotating rod 26. The structure employs a rotating connection between supporting half-ring 22, supporting half-ring 23, and rotating rod 26. Disassembly eliminates the need to disassemble each frame component individually; simply releasing the fixing constraints on supporting half-ring 22 and supporting half-ring 23 allows the two supporting half-rings to be folded together by rotating rod 26 around side plate 25. Simultaneously, the upright 21 is fixed to the bottom of the inner surface of the covering film 11. After folding, the covering film 11 folds synchronously with the closing of the supporting half-rings, making folding and storage convenient and significantly reducing the labor intensity of disassembly.

[0018] After the supporting half-ring 22 and supporting half-ring 23 are folded together, the tops of the supporting half-ring 22 and supporting half-ring 23 are supported on the top of the inner surface of the covering film 11. When the supporting semi-ring 1 22 and supporting semi-ring 2 23 are unfolded, their tops will support the inner surface of the covering film 11.

[0019] A bottom frame 27 is provided on one side of the bottom of the supporting semi-ring 23. An internal threaded ring 28 is provided at the bottom of the bottom frame 27. A threaded rod 29 is threadedly connected to the middle of the internal threaded ring 28. The top of the threaded rod 29 abuts against the bottom of the supporting half-ring 22, and a handle 291 is fixedly connected to the bottom of the threaded rod 29; After the support half-ring 1 22 and support half-ring 23 are unfolded, turn the handle 291 to drive the threaded rod 29 to rotate, so that the top of the threaded rod 29 abuts against the bottom of the support half-ring 1 22, thereby fixing the support half-ring 1 22 and support half-ring 23 after unfolding.

[0020] Working Principle: When the cotton seedling stage ends or frost protection is no longer required, the device needs to be folded and stored for easy carrying and storage. The operator first rotates handle 291 counterclockwise to completely disengage the threaded rod 29 from the contact state with the supporting half-ring 22, releasing the height fixation of the arc-shaped support structure. Then, the two uprights 21 are pushed towards the center. The uprights 21 drive the supporting half-ring 22 and supporting half-ring 23 to move synchronously towards the center. The support block 24 at the end of supporting half-ring 23 rotates in the opposite direction along the outer surface of the rotating rod 26, causing the two half-rings to gradually retract from their arc-shaped unfolded state. Because the structural dimensions of supporting half-ring 22 and supporting half-ring 23 match, they can completely fit together after retraction. The covering film 11 shrinks and folds synchronously with the retraction of the half-rings, preventing wrinkles or damage.

[0021] In this step, the rotation of the rotating rod 26 and the support block 24 cooperate to realize the folding and unfolding of the support structure. The height is precisely adjusted through the threaded transmission mechanism. The entire operation can be completed without complicated tools, so that the covering film 11 always maintains a stable support state suitable for the growth of cotton seedlings, while taking into account both ease of use and storage flexibility.

[0022] Please see Figure 1-5As shown, this embodiment is based on the above embodiment: It also includes a support component, which includes a bottom cone 31, a support plate 32 and a column 34. The support plate 32 is fixed to the bottom of the column 21. The bottom of the inner surface of the column 21 is a cavity. The column 34 is slidably connected inside the cavity. The bottom cone 31 is fixed to the bottom of the column 34. When in use, the bottom cone 31 can penetrate 15-20cm into the soil to form an anchoring effect, and the support plate 32 fits against the ground to increase the force-bearing area and prevent the device from tilting due to soft soil or slight collisions.

[0023] Guide grooves 33 are provided on the lower part of both sides of the outer surface of the upright 21, and guide rods 35 are provided on the upper part of both sides of the outer surface of the upright 34. The guide rods 35 are slidably connected inside the guide grooves 33. The cooperation between the guide groove 33 and the guide rod 35 ensures that the column 34 does not deviate during the downward movement and always remains vertical.

[0024] The guide rod 35 is externally threaded with a retaining ring 36, and the side of the retaining ring 36 is fastened to the lower part of one side of the outer surface of the upright rod 21. The guide rod 35 is locked in position by the friction between the fixing ring 36 and the upright 21, thereby fixing the relative position of the upright 34 and the upright 21, completing the installation and fixing of the support components, so that the whole device is not easy to tip over due to external forces such as strong winds and collisions.

[0025] Working principle: During operation, the operator first moves the device to the predetermined position in the cotton seedling planting bed, so that the support plate 32 at the bottom of the upright 21 is in contact with the ground. Then, the upright 34 is pulled down, and the upright 34 slides vertically down along the cavity of the upright 21. At the same time, the guide rod 35 on the outer surface of the upright 34 slides synchronously along the guide grooves 33 on both sides of the upright 21, so that the bottom cone 31 at the bottom of the upright 34 is fully inserted into the soil. At this time, the fixing ring 36 on the outside of the guide rod 35 is rotated, so that the side of the fixing ring 36 is screwed in along the thread of the guide rod 35 and tightly attached to the lower part of the outer surface of the upright 21.

[0026] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
