Description

Technical Field

[0001] This utility model relates to the field of tea planting technology, and in particular to an early spring frost protection device for tea planting greenhouses. Background Technology

[0002] Tea leaves are the tender leaves and buds of a perennial evergreen shrub or small tree. After processing, they can be used as a beverage. Rich in tea polyphenols, caffeine, and other components, tea is a widely consumed beverage ingredient worldwide and an important economic crop. During the cultivation of tea, it is necessary to pay attention to frost protection in early spring. Therefore, greenhouses need to be erected in the tea-growing areas to prevent the tea leaves from being damaged by low temperatures. The greenhouse is mainly composed of a supporting frame and a plastic film. Before erecting the greenhouse, the supporting frame is first fixed to the ground, and then the plastic film is covered on the surface of the supporting frame.

[0003] When fixing the support frame to the ground, a trench needs to be dug first, then the support frame is placed in the trench, and finally backfilled to fix the support frame. This fixing requires digging and backfilling, which is cumbersome and time-consuming. Therefore, this application provides an early spring frost protection device for tea planting greenhouses to meet the needs. Summary of the Invention

[0004] This utility model provides an early spring frost protection device for tea planting greenhouses to solve the problem of the long time required to fix the support frame to the ground.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A spring frost protection device for tea greenhouses includes a supporting frame and a film covering the surface of the supporting frame, and further includes:

[0007] The fixing mechanism includes a fixing seat, a fixing groove on the top of the fixing seat, a support frame inserted into the fixing groove, a fixing bolt threaded to the side of the fixing seat, the end of the fixing bolt abutting against the side of the support frame, and a grounding component fixed to the bottom of the fixing seat. Before the support frame is installed, the fixing seat is pre-fixed to the ground by the grounding component.

[0008] Preferably, an extrusion plate is slidably connected inside the fixing groove, the extrusion plate is attached to the side of the support frame, and the end of the fixing bolt is rotatably connected to the side of the extrusion plate.

[0009] Preferably, the extrusion plate is provided with locking teeth on the side near the support frame, and the locking teeth are inclined downwards.

[0010] Preferably, the ground insertion component includes a vertical part one fixed to the bottom of the fixing base, the bottom of the vertical part one being integrally formed with an inclined part, the bottom of the inclined part being integrally formed with a vertical part two, the top of the inclined part being away from the middle of the greenhouse, and the bottom of the inclined part being close to the middle of the greenhouse.

[0011] Preferably, the bottom of the second vertical part is provided with a pointed tip.

[0012] Preferably, a rotating plate is rotatably connected to the side of the inclined part away from the greenhouse, and a support plate is inclinedly provided on the side of the vertical part away from the greenhouse. A connecting bolt is rotatably connected to the surface of the rotating plate. After the rotating plate rotates upward, the connecting bolt is threaded onto the surface of the inclined part. During the process of inserting the ground piece into the ground, the surface of the rotating plate is attached to the top of the support plate. At this time, the rotating plate is parallel to the ground. After the film is covered, the rotating plate rotates upward to fix the film.

[0013] Preferably, a rotating shaft is movably inserted through the side of the rotating plate near the bottom position, and a support seat is fixed at the end of the rotating shaft. The support seat is fixed on the side of the inclined part, and after the vertical part is inserted into the ground, the bottom of the support seat is supported on the ground.

[0014] Compared with the prior art, this utility model has at least the following beneficial effects:

[0015] In the above solution, by setting a fixing base and a ground insert, the ground insert is first inserted into the ground to fix the fixing base before the support frame is installed. Then the support frame can be inserted into the fixing base to fix the support frame. In this way, there is no need to dig a trench and then backfill it during the fixing process, making the operation more convenient and taking less time.

[0016] By incorporating a sloping section, snow slides down the plastic film and accumulates at the edge of the greenhouse. The sloping design of the greenhouse causes the bottom to contract inward, effectively preventing snow accumulation from squeezing the bottom of the greenhouse and protecting the bottom film from damage.

[0017] By setting up a rotating plate and a support base, when the ground insert needs to be inserted, the rotating plate is attached to the top of the support plate and kept parallel to the ground. At this time, the operator can step on the surface of the rotating plate and exert downward force to make the ground insert more easily embedded in the ground. After the vertical part is inserted into the ground, the bottom of the support base is attached to the ground. The support base plays a limiting role to prevent the ground insert from being inserted too far into the ground. After the film is covered, the film is first attached to the surface of the inclined part, and then the rotating plate is flipped upward to make it tightly pressed against the outside of the film. Then, the rotating plate is fixed to the inclined part by connecting bolts, which can achieve a stable clamping of the film and ensure that the film is not easy to loosen or fall off in subsequent use.

Detailed Implementation

[0026] The following is a detailed description of an early spring frost protection device for tea planting greenhouses provided by this utility model, in conjunction with the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0027] like Figures 1-6 As shown, an embodiment of this utility model provides an early spring frost protection device for tea planting greenhouses, including a support frame 1 and a film 2 covering the surface of the support frame 1. After the film 2 covers the support frame 1, a flip-up door for entry and exit is provided at the end of the whole. It also includes:

[0028] The fixing mechanism 3 includes a fixing seat 4, with a fixing groove 5 on the top of the fixing seat 4. The support frame 1 is inserted into the fixing groove 5. The fixing seat 4 is threaded with fixing bolts 6 on its side, with the ends of the fixing bolts 6 abutting against the side of the support frame 1. The bottom of the fixing seat 4 is fixed with a ground insert 9. Before the support frame 1 is installed, the fixing seat 4 is pre-fixed to the ground by the ground insert 9. The ground insert 9 can be directly inserted into the ground to achieve the pre-fixation of the fixing seat 4, eliminating the step of digging trenches and backfilling, greatly simplifying the installation process of the support frame 1 and saving construction time. After the support frame 1 is inserted into the fixing groove 5, it is tightened by the fixing bolts 6, which can quickly complete the positioning and fixing, ensuring that the support frame 1 is installed firmly, providing stable support for the overall structure of the greenhouse, ensuring the sealing of the film 2 after covering, and enhancing the early spring anti-freezing effect.

[0029] like Figure 5 As shown in this embodiment, a pressing plate 7 is slidably connected inside the fixing groove 5. The pressing plate 7 is attached to the side of the support frame 1. The end of the fixing bolt 6 is rotatably connected to the side of the pressing plate 7. The pressing plate 7 increases the contact area between the fixing bolt 6 and the support frame 1, so that the fixing force is applied to the support frame 1 more evenly, avoiding deformation of the support frame 1 due to excessive local force. At the same time, the pressing plate 7 can slide flexibly with the rotation of the fixing bolt 6, ensuring that support frames 1 of different sizes can be tightly clamped, improving the versatility and fixing stability of the fixing mechanism 3.

[0030] like Figure 5 As shown in this embodiment, the compression plate 7 is provided with a locking tooth 8 on the side near the support frame 1. The locking tooth 8 is inclined downward and can be embedded into the surface of the support frame 1 to form a one-way locking structure. This effectively prevents the support frame 1 from loosening upward or falling out of the fixing groove 5 under the action of gravity or external force, further enhancing the connection between the support frame 1 and the fixing seat 4, and ensuring that the greenhouse frame remains stable under the impact of external forces such as wind and snow.

[0031] like Figures 4-6 As shown in this embodiment, the ground insertion component 9 includes a vertical part 10 fixed to the bottom of the fixing base 4. The bottom of the vertical part 10 is integrally formed with an inclined part 11, and the bottom of the inclined part 11 is integrally formed with a vertical part 2 12. The top of the inclined part 11 is far away from the middle of the greenhouse, and the bottom of the inclined part 11 is close to the middle of the greenhouse. The inclination angle of the inclined part 11 makes the bottom of the greenhouse have an inward contraction structure. When the snow slides down the film 2 to the edge of the greenhouse, it can guide the snow to accumulate in a direction away from the bottom of the greenhouse, avoid the snow from directly squeezing the bottom film 2, reduce the risk of damage to the film 2 due to long-term pressure, extend the service life of the film 2, and ensure the heat preservation and antifreeze performance of the greenhouse. The vertical part 10 and the vertical part 2 12 enhance the overall structural strength of the ground insertion component 9, ensuring that the fixing base 4 is not easy to tip over after installation.

[0032] like Figures 4-6 As shown in this embodiment, the bottom of the vertical part 2 12 is set with a pointed tip. The pointed tip design reduces the contact area when the vertical part 2 12 is inserted into the ground, reduces the resistance of the soil to the insertion part 9, and makes it easier for the operator to embed the insertion part 9 into the ground, thereby improving the installation efficiency of the fixing base 4. It is especially suitable for tea garden environments with hard soil.

[0033] like Figures 3-6 As shown in this embodiment, a rotating plate 13 is rotatably connected to the side of the inclined part 11 away from the greenhouse, and a support plate 16 is inclinedly set on the side of the vertical part 12 away from the greenhouse. A connecting bolt 17 is rotatably connected to the surface of the rotating plate 13. After the rotating plate 13 rotates upward, the connecting bolt 17 is threadedly connected to the surface of the inclined part 11. During the process of inserting the grounding component 9 into the ground, the surface of the rotating plate 13 is attached to the top of the support plate 16. At this time, the rotating plate 13 is set parallel to the ground. After the film 2 is covered, the rotating plate 13 rotates upward to fix the film 2. When inserting the grounding component 9, the rotating plate 13 is attached to the support plate 16 and parallel to the ground, providing a fulcrum for the operator. Stepping on the rotating plate 13 can easily press the grounding component 9 into the ground with the help of the body weight, reducing the installation difficulty. After the film 2 is covered, the rotating plate 13 flips upward and is fixed by the connecting bolt 17, which can tightly press the film 2 onto the surface of the inclined part 11, preventing the film 2 from loosening due to wind or vibration, ensuring the airtightness of the greenhouse, reducing heat loss, and enhancing the early spring anti-freezing effect.

[0034] like Figure 3 As shown in this embodiment, a rotating shaft 15 is movably inserted through the side of the rotating plate 13 near the bottom. A support seat 14 is fixed to the end of the rotating shaft 15. The support seat 14 is fixed to the side of the inclined part 11. After the vertical part 12 is inserted into the ground, the bottom of the support seat 14 is supported on the ground. The rotating shaft 15 provides a stable rotating shaft for the rotating plate 13, ensuring that its rotation process is flexible and smooth. After the ground insertion part 9 is installed in place, the support seat 14 contacts the ground. On the one hand, it plays a limiting role to prevent the ground insertion part 9 from being inserted too deeply into the ground, causing the fixed seat 4 to be too low. On the other hand, it increases the contact area between the ground insertion part 9 and the ground, improves the overall stability of the fixing mechanism 3, and prevents the greenhouse from tilting or settling under the action of external forces.

[0035] Working principle: When installing the early spring anti-freezing device for tea planting greenhouse, first attach the rotating plate 13 to the top of the support plate 16 so that it is parallel to the ground. The operator steps on the rotating plate 13 and exerts force downwards. The pointed tip at the bottom of the vertical part 12 is used to insert the ground insert 9 into the ground until the bottom of the support base 14 is in contact with the ground, thus completing the pre-fixing of the fixing base 4.

[0036] Then, the support frame 1 is inserted into the fixing groove 5 of the fixing seat 4, the fixing bolt 6 is tightened, the pressing plate 7 is pushed to fit the support frame 1, and the clamping teeth 8 are tilted downward to clamp the support frame 1, thereby fixing the support frame 1.

[0037] After covering the film 2, the film 2 is attached to the surface of the inclined part 11, and the rotating plate 13 is flipped upward to press it against the outside of the film 2. The rotating plate 13 is fixed to the inclined part 11 by the connecting bolt 17 to complete the fixing of the film 2.

[0038] During use, the snow slides down the film 2 to the edge of the greenhouse. The inclined part 11 is designed to contract inward at the bottom, which prevents the snow from squeezing the bottom film 2.

[0039] During disassembly, unscrew the connecting bolt 17, flip open the rotating plate 13, remove the film 2, loosen the fixing bolt 6, remove the support frame 1, and then pull out the grounding part 9.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
