A detachable greenhouse for cherry seedling cultivation

Abstract

This utility model discloses a detachable greenhouse for cherry seedling cultivation, belonging to the technical field of seedling greenhouses. Its key technical features include three arc frames, each with a welded support sleeve and a locking rod inside. Greenhouse film doors are bolted to the outer sides of both the front and rear arc frames. This application utilizes a film-rolling and unrolling mechanism, employing an external controller to control a servo motor that drives the main and secondary gears to mesh and transmit power, thereby automating the film rolling and unrolling. The welded support sleeves and locking rods inside the arc frames use a locking structure, replacing the traditional method of extensive welding or bolting. Disassembly requires no tools, is simple to operate, and is less likely to damage the arc frames. The film-rolling and unrolling mechanism, driven by a servo motor, allows the film to be smoothly rolled up and down along the top of the arc frames, avoiding tearing and pulling during manual disassembly. This solves the problems of cumbersome film-rolling operations and high damage rates, improving rolling efficiency and material reuse rate.

In order to increase the productivity of crops, people have adopted greenhouse cultivation technology. In the process of cherry seedling cultivation, greenhouses play a key role as important protective facilities in regulating the growth environment of seedlings.

[0003] However, existing traditional cherry seedling greenhouses mostly use welded or bolted steel structures, which have problems such as difficulty in disassembling the frame and easy damage. At the same time, the film covering the surface is cumbersome to disassemble and is easily torn, resulting in low material reuse rate. In addition, the greenhouse film lacks efficient automated mechanisms during the rolling process, making it difficult to achieve convenient rolling and unfolding of the film, which affects the efficiency of greenhouse use and film reuse.

[0004] Therefore, a detachable greenhouse for cherry seedling cultivation is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a detachable greenhouse for cherry seedling cultivation, which can solve the problems of existing traditional cherry seedling greenhouses, which mostly use welded or bolted steel structures, resulting in difficult disassembly and easy damage to the frame.

[0025] 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.

[0026] Please see Figure 1-6 The present invention provides the following technical solution:

[0027] A detachable greenhouse for cherry seedling cultivation includes three arc frames 1. The inside of the arc frame 1 is welded with a support sleeve 2. The inside of the support sleeve 2 is clamped with a fixing rod 3. The outer sides of the front arc frame 1 and the rear arc frame 1 are both bolted with greenhouse film doors 4. The top of the arc frame 1 is equipped with a film opening and closing mechanism 5.

[0028] The film loading and unloading mechanism 5 includes a film box 501 bolted to the top of the arc frame 1. A carrier plate 502 is welded to the bottom of the front side of the film box 501. A servo motor 503 is provided on the right side of the top of the carrier plate 502. The servo motor 503 is used with an external controller. A main gear 504 is fixedly connected to the output end of the servo motor 503. A secondary gear 505 is rotatably connected to the left side of the front side of the film box 501. The secondary gear 505 meshes with the main gear 504. Film rollers 506 are fixedly connected to the rear sides of both the secondary gear 505 and the main gear 504. The film rollers 506 are rotatably connected to both sides inside the film box 501. A covering film 507 is provided on the outer side of the film roller 506. The covering film 507 is located on the top of the arc frame 1. A counterweight structure 508 is provided on the front side of the secondary gear 505.

[0029] In this embodiment: by setting up an arc frame 1, a support sleeve 2, a fixing rod 3, a greenhouse film door 4, and a film retraction and dismantling mechanism 5, the arc frame 1 serves as the main support. The support sleeve 2 and the fixing rod 3 welded inside the arc frame 1 adopt a snap-fit ​​design, allowing the fixing rod 3 to be separated from the support sleeve 2 without tools during disassembly, thus quickly disassembling the greenhouse frame. Compared with traditional welded or bolted structures, this significantly reduces the difficulty of disassembly and avoids damage to the overall frame, facilitating reuse. The greenhouse film door 4 on the outer side of the front and rear arc frame 1 adopts a bolted connection, which can be easily disassembled, meeting the needs of personnel and material access. Together with the top film retraction and dismantling mechanism 5, it forms an overall detachable covering system. The film retraction and dismantling mechanism 5 is controlled by an external controller via a servo motor 503. In operation, the servo motor 503 drives the main gear 504 to rotate. The main gear 504 meshes with the secondary gear 505 to drive the film rollers 506 on both sides to rotate synchronously, realizing the automatic winding and unfolding of the film 507. The film 507 is laid along the top of the arc frame 1. The uniform winding and unfolding process driven by the servo motor 503 avoids the pulling and damage caused by manual operation. The counterweight structure 508 on the front side of the secondary gear 505 forms a balancing torque during winding, which counteracts the unilateral tension of the film roller 506 and prevents the film 507 from wrinkling or breaking due to uneven force. This ensures a stable and smooth winding process, further improving the winding and unfolding efficiency and service life of the film 507, and effectively solving the problems of cumbersome disassembly, easy damage and low winding efficiency of traditional greenhouse films.

[0030] Specifically, such as Figure 3 As shown, the counterweight structure 508 includes a connecting rod 5081 welded to the front side of the secondary gear 505, and a gravity wheel 5082 welded to the front side of the connecting rod 5081.

[0031] Specifically, such as Figure 3As shown, a speed-reducing sleeve 5083 is provided on the left side of the front side of the carrier plate 502, and the speed-reducing sleeve 5083 is located on the outside of the gravity wheel 5082.

[0032] Specifically, such as Figure 3 As shown, the deceleration sleeve 5083 has a friction arc plate 5084 inside, and the inner wall of the friction arc plate 5084 is in contact with the outer side of the gravity wheel 5082.

[0033] In this embodiment: By setting a counterweight structure 508, the connecting rod 5081 on the front side of the secondary gear 505 and the gravity wheel 5082 constitute a basic counterweight component. When the film roller 506 winds up the film 507, the gravitational torque generated by the gravity wheel 5082 can balance the unilateral tension of the film roller 506, avoiding uneven force on the film 507. In conjunction with the friction arc plate 5084 inside the speed reduction sleeve 5083 contacting the gravity wheel 5082, the winding speed is further adjusted by friction to prevent the film 507 from being stretched, deformed or broken due to excessive speed, ensuring that the film 507 is wound up smoothly.

[0034] Specifically, such as Figure 5 As shown, base plates 6 are welded to both sides of the bottom of the arc frame 1, and soil-penetrating pressure heads 7 are welded to the bottom of the base plates 6.

[0035] Specifically, such as Figure 5 As shown, the top of the base plate 6 is provided with a slot 8, and a positioning cone 9 is provided inside the slot 8.

[0036] In this embodiment: by setting the base plate 6, the soil-penetrating head 7, the slot 8 and the positioning cone 9, the base plate 6 at the bottom of the arc frame 1 provides a stable support surface, the soil-penetrating head 7 can be directly inserted into the ground to enhance the overall wind resistance of the arc frame 1, and the positioning cone 9 in the slot 8 can further fix the position of the base plate 6 to prevent the greenhouse from shifting or shaking due to external forces during use, effectively improving the stability and reliability of the greenhouse structure.

[0037] Specifically, such as Figure 6 As shown, a magnetic sleeve 10 is fixedly connected to the inner side of the top of the base plate 6, and the magnetic sleeve 10 is located at the bottom of the film 507.

[0038] Specifically, such as Figure 6 As shown, a counterweight magnet post 11 is fixedly connected to the bottom of the film 507, and the counterweight magnet post 11 is magnetically connected to the magnetic sleeve 10.

[0039] In this embodiment: by setting up a magnetic sleeve 10 and a counterweight magnet column 11, the counterweight magnet column 11 at the bottom of the film 507 is attracted and connected to the magnetic sleeve 10 at the top of the base plate 6, which can fix the position of the film 507 in the non-winding state, and prevent the film 507 from shifting or being lifted due to wind or other factors. When it is necessary to wind up the film 507, the counterweight magnet column 11 is manually pulled out to remove it from the magnetic sleeve 10, eliminating magnetic resistance and ensuring that the film 507 can rise stably and wind up smoothly under the drive of the film roller 506.

[0040] Working Principle: In the use of the detachable greenhouse for sweet cherry seedling cultivation, the arc frame 1 serves as the overall support frame. Its internal welded support sleeves 2 and snap-fit ​​fixing rods 3 form a detachable skeleton structure, allowing for quick disassembly without tools, facilitating greenhouse relocation or reuse. The greenhouse film doors 4, bolted to the outer sides of the front and rear arc frames 1, facilitate personnel entry and exit and material transportation. When it is necessary to adjust the greenhouse film covering 507 status, the servo motor 503 is activated via an external controller. The main gear 504 drives the secondary gear 505 to rotate synchronously, thereby enabling the two film rollers 506 on both sides to automatically wind up or unwind the film coating 507. In the counterweight structure 508 on the front side of the secondary gear 505, the torque generated by the gravity wheel 5082 can balance the unilateral tension of the film roller 506 during winding. In conjunction with the contact between the friction arc plate 5084 inside the speed reduction sleeve 5083 and the gravity wheel 5082, the winding speed is adjusted by friction to prevent the film coating 507 from wrinkling due to uneven force or excessive speed. The film 507 is designed to withstand breakage and ensure stable opening and closing. During the installation and fixing stage of the greenhouse, the bottom plate 6 at the bottom of the arc frame 1 provides a stable support surface. The soil-penetrating pressure head 7 is inserted into the ground to enhance wind resistance. The positioning cone 9 in the slot 8 further fixes the position of the bottom plate 6 to prevent the greenhouse from shifting due to external forces. The counterweight magnet column 11 at the bottom of the film 507 is attracted and connected to the magnetic sleeve 10 at the top of the bottom plate 6, fixing the film 507 in the non-rolled state to prevent it from being lifted by the wind. When it is necessary to roll up the film 507, the counterweight magnet column 11 is manually pulled to release the magnetic connection, eliminating resistance and allowing the film 507 to be smoothly rolled up under the drive of the film roller 506, achieving efficient control and convenient management of the greenhouse environment. It can be further noted that, depending on the local environment, inclined steel cables or wind-resistant supports can be added to both sides of the arc frame 1, or inclined supports can be added inside to enhance the overall stability of the greenhouse in strong wind environments. Also, the gravity wheel 5082 weighs 5-10kg and balances 10-20m through the lever principle. 2 The winding tension of the coating and the rubber material of the friction arc plate 5084 can effectively control the winding speed at 0.3-0.5m / s, avoiding damage to the coating 507 caused by sudden speed changes.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
