An automatic lifting device for agricultural greenhouse insulation curtains

Abstract

This utility model provides an automatic lifting device for agricultural greenhouse insulation curtains. It includes a greenhouse body and a guide rail. Toothed plates are installed on both sides of the guide rail, and a movable plate is slidably mounted on the guide rail. A mounting seat is mounted on the movable plate, and a connecting plate is installed on the side of the mounting seat. A motor is installed inside the connecting plate. In this utility model, only one end of the insulation curtain needs to be fixed to the side of the greenhouse body. Subsequently, driven by the motor, the roll-up shaft moves on the guide rail and rotates autonomously. This process can automatically unfold the insulation curtain to evenly cover the greenhouse, and can also quickly roll it up as needed. This not only saves a lot of manpower but also responds instantly to changes in temperature and humidity inside the greenhouse, achieving precise control of the greenhouse environment. Furthermore, by rotating the bidirectional threaded rod, the expansion and contraction plate can be driven to expand and contract with the help of the connecting plate, thus facilitating the complete removal, maintenance, and replacement of the rolled-up insulation curtain.

Description

Technical Field

[0001] This utility model relates to the installation of agricultural greenhouse accessories, and in particular to an automatic lifting device for agricultural greenhouse insulation curtains, belonging to the field of agricultural equipment technology. Background Technology

[0002] Automatic lifting equipment for greenhouse insulation curtains is a key piece of equipment in modern agriculture for precise control of the greenhouse environment (temperature, light, etc.). By automatically controlling the raising and lowering of the insulation curtains, it replaces traditional manual operation, improving greenhouse management efficiency and crop growth quality.

[0003] Publication number CN205337046U discloses a greenhouse insulation curtain, comprising an upper waterproof layer and a lower waterproof layer below the upper waterproof layer. At least three layers of foam filling are bonded between the upper and lower waterproof layers, and an anti-radiation insulation coating is applied between adjacent foam filling layers. A far-infrared fiber layer is also bonded to the upper surface of the lower waterproof layer. This greenhouse insulation curtain features a multi-layered foam filling structure, providing excellent thermal insulation. The anti-radiation insulation coating further enhances the insulation effect through heat radiation reflection. Simultaneously, the far-infrared fiber layer provides far-infrared heating, resulting in superior thermal insulation. Furthermore, the curtain is lightweight, easy to roll and unroll, and has a long service life.

[0004] However, the installation of traditional insulation curtains requires manual dragging. The heavy curtains are laboriously pulled to the top of the greenhouse and then smoothed out for covering. This process is time-consuming and labor-intensive. In daily management, the temperature and humidity inside the greenhouse change dynamically with the external climate and the crop growth stage, requiring frequent raising and lowering of the insulation curtains. For example, the curtains need to be lowered in the early morning in winter for insulation, rolled up for ventilation when the temperature rises at noon, and then covered again in the evening. This repeated operation relies entirely on manual climbing of the greenhouse and manual pulling, which is labor-intensive and makes it difficult to accurately control the greenhouse environment. Therefore, improvements are needed.

[0005] To address this, an automatic lifting device for agricultural greenhouse insulation curtains is proposed. Utility Model Content

[0006] In view of this, the present invention provides an automatic lifting device for agricultural greenhouse insulation curtains to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0007] The technical solution of this utility model is implemented as follows: An automatic lifting device for agricultural greenhouse insulation curtains includes a greenhouse body and a guide rail. Toothed plates are installed on both sides of the guide rail. A movable plate is slidably installed on the guide rail. An installation seat is installed on the movable plate. A connecting plate is installed on the side of the installation seat. A motor is installed inside the connecting plate. Gear A is installed at the output end of the motor. Connecting shafts are rotatably installed on both sides of the installation seat. One end of the connecting shaft is connected to a winding shaft through a quick-release mechanism. Gear B is installed on the winding shaft. A limit groove is provided on the winding shaft. A bidirectional threaded rod is rotatably installed inside the winding shaft. A threaded seat is threadedly connected to the bidirectional threaded rod. A connecting seat A is installed on the threaded seat. A connecting plate is hinged inside the connecting seat A. A connecting seat B is hinged to the connecting plate. An expansion and contraction plate is installed on the connecting seat B.

[0008] More preferably, gear A meshes with gear B, and gear A meshes with a toothed plate.

[0009] More preferably, the bidirectional threaded rod is provided with two sets of opposite threads, and a knob is installed at one end of the bidirectional threaded rod.

[0010] More preferably, the connecting plate is disposed within the limiting groove.

[0011] More preferably, the quick-release mechanism includes a T-block, a top pin, a slider, a stop plate, and a tension spring. The T-block is mounted on the connecting shaft, the top pin is mounted on the side of gear B, the slider is slidably mounted on the top pin, the stop plate is mounted on the slider, and the tension spring is sleeved on the top pin.

[0012] More preferably, the unwinding shaft is provided with a slot adapted to the T-shaped block, and the abutment is slidably disposed on the connecting shaft.

[0013] More preferably, one end of the tension spring is mounted on the top pin, and the other end of the tension spring is mounted on the gear B, and the tension spring drives the abutment plate to tend to cover the T-block.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] I. In this utility model, one end of the insulation curtain is fixed to the side of the greenhouse. Then, the motor drives the unwinding shaft to move on the slide rail and rotate autonomously. This process can automatically unfold the insulation curtain and evenly cover the greenhouse, and can also quickly roll it up as needed. This not only saves a lot of manpower, but also responds to changes in temperature and humidity in the greenhouse in real time, achieving precise control of the greenhouse environment. In addition, by rotating the bidirectional threaded rod, the expansion and contraction plate can be driven to expand and contract under the action of the connecting plate, which makes it easy to remove the rolled-up insulation curtain for maintenance and replacement.

[0016] Second, in this utility model, when a fine inspection of the winding shaft is required, no complicated tools are needed; only two simple actions, "pull and tug," are required to quickly separate the winding shaft from the mounting base. After maintenance, the shaft can be easily reinstalled by simply "pull, align, insert, and release." This quick-release mechanism not only significantly shortens maintenance time and lowers the operational threshold, but also offers high practicality.

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figure 1-6 As shown, this utility model embodiment provides an automatic lifting device for agricultural greenhouse insulation curtains, including a greenhouse body 1 and a guide rail 2. Toothed plates 3 are installed on both sides of the guide rail 2. A movable plate 4 is slidably installed on the guide rail 2. An installation seat 5 is installed on the movable plate 4. A connecting plate 6 is installed on the side of the installation seat 5. A motor 7 is installed inside the connecting plate 6. A gear A8 is installed at the output end of the motor 7. A connecting shaft 18 is rotatably installed on both sides of the installation seat 5. One end of the connecting shaft 18 is connected to a winding shaft 10 through a quick-release mechanism. A gear B9 is installed on the winding shaft 10. A limit groove 11 is provided on the winding shaft 10. A bidirectional threaded rod 12 is rotatably installed inside the winding shaft 10. A threaded seat 13 is threadedly connected to the bidirectional threaded rod 12. A connecting seat A14 is installed on the threaded seat 13. A connecting plate 15 is hinged inside the connecting seat A14. A connecting seat B16 is hinged on the connecting plate 15. An expansion and contraction plate 17 is installed on the connecting seat B16.

[0029] In one embodiment, gear A8 meshes with gear B9, and gear A8 meshes with gear plate 3. After starting motor 7, under the meshing action of gear A8 and gear plate 3, moving plate 4 will slide along guide rail 2, and at the same time, under the meshing action of gear A8 and gear B9, winding shaft 10 will also rotate.

[0030] In one embodiment, the bidirectional threaded rod 12 has two sets of opposing threads, and a knob is installed at one end of the bidirectional threaded rod 12. When the bidirectional threaded rod 12 is rotated, the threaded seat 13 will slide axially along the bidirectional threaded rod 12 under the action of the threads.

[0031] In one embodiment, the connecting plate 15 is disposed within the limiting groove 11. The connecting plate 15 changes angle and position under the drive of the threaded seat 13, and under the mechanical coupling with the connecting seat A14 and the connecting seat B16, it drives the expansion and contraction plate 17 to expand and contract.

[0032] In one embodiment, the quick-release mechanism includes a T-block 19, a top pin 20, a slider 21, a stop plate 22, and a tension spring 23. The T-block 19 is mounted on the connecting shaft 18, the top pin 20 is mounted on the side of the gear B9, the slider 21 is slidably mounted on the top pin 20, the stop plate 22 is mounted on the slider 21, and the tension spring 23 is sleeved on the top pin 20. When fine maintenance of the winding shaft 10 is required, no complicated tools are needed; only two simple actions, "pull and pull," are required to quickly separate the winding shaft 10 from the mounting base 5. After maintenance, the installation and reinstallation can be easily completed through the convenient operation of "pull, align, insert, and release."

[0033] In one embodiment, the unwinding shaft 10 is provided with a slot adapted to the T-block 19, and the abutment 22 is slidably disposed on the connecting shaft 18. The T-block 19 and the slot can provide a lateral limiting effect, while the abutment 22 can provide a vertical limiting effect.

[0034] In one embodiment, one end of the tension spring 23 is mounted on the top pin 20, and the other end of the tension spring 23 is mounted on the gear B9. The tension spring 23 drives the abutment plate 22 to tend to cover the T-block 19. Under the action of the tension spring 23, the abutment plate 22 is driven to reset and abut against the T-block 19, thereby completing the fixation.

[0035] In operation, the following steps are taken: First, one end of the insulation curtain is fixed to the side of the bottom of the greenhouse. After starting the motor 7, the moving plate 4 slides along the guide rail 2 under the meshing action of gear A8 and toothed plate 3. Simultaneously, the winding shaft 10 rotates under the meshing action of gear A8 and gear B9. During the rotation of the winding shaft 10, the insulation curtain can be automatically unfolded or rolled up. In this process, the toothed plates 3 on both sides of the guide rail 2 provide a stable meshing foundation for gear A8, ensuring that the movement and rotation are synchronized, allowing the insulation curtain to evenly cover the greenhouse or neatly roll up, meeting the greenhouse's needs for insulation or ventilation. When the rolled-up insulation curtain needs to be removed for maintenance and replacement, first rotate the double-threaded rod 12. Under the action of the thread, the threaded seat 13 will slide along the axial direction of the double-threaded rod 12. The connecting plate 15 will change its angle and position under the drive of the threaded seat 13. Under the mechanical coupling between the connecting seat A14 and the connecting seat B16, it will drive the expansion and contraction plate 17 to expand and contract, thus facilitating the removal of the insulation curtain along the roll-up shaft 10. When the roll-up shaft 10 needs fine maintenance, first move the slider 21 to disengage the abutment plate 22 from the T-block 19, and drive the tension spring 23 to stretch, so that the roll-up shaft 10 can be pulled out and separated from the connecting shaft 18. During installation, the T-block 19 needs to be aligned with the slot and inserted. Then release the slider 21. Under the action of the tension spring 23, the abutment plate 22 will be driven to reset and abut against the T-block 19 again, thus completing the fixation. The whole process is convenient and efficient and does not affect the overall working rhythm of the equipment.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
