Technical Field

[0001] This utility model relates to the field of agricultural greenhouse technology, specifically to an agricultural greenhouse with an automatic rolling shutter function. Background Technology

[0002] Agricultural greenhouse seedling raising devices are used in agricultural production, particularly in greenhouse or polytunnel environments, for seedling cultivation. They are typically designed to control environmental conditions, providing suitable temperature, humidity, and light to help seeds or seedlings achieve optimal growth conditions in their early stages. These devices offer a stable and controlled environment, allowing seeds or seedlings to thrive under unique climatic conditions. This is crucial for improving seed germination rates, promoting seedling growth, and increasing crop yields.

[0003] Currently used agricultural greenhouses typically have curtain-type entrances. These curtains close by their own weight. However, these curtains take up considerable space and reduce transport efficiency. Furthermore, in windy winter weather, they can blow the curtains open, allowing strong winds to enter the greenhouse and negatively impact crop growth, thus failing to provide adequate protection.

[0004] Therefore, we propose an agricultural greenhouse with an automatic rolling shutter function to solve the problems mentioned above. Utility Model Content

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] Example 1

[0027] Please see Figure 1-7 An agricultural greenhouse with an automatic rolling shutter function includes a greenhouse body 1 and a roof 2 installed on the top of the greenhouse body 1. An opening is provided at the middle of the front side of the greenhouse body 1, and a door frame 3 is installed in the inner cavity of the opening (a controller is installed on the front side of the door frame 3). A U-shaped block 4 is fixedly installed at the bottom of the inner cavity of the greenhouse body 1 near the middle position. A groove 5 is provided on the rear side of the inner cavity of the U-shaped block 4, and a limit component 7 is provided in the inner cavity of the groove 5. A rolling shutter component 6 is provided on the rear side of the door frame 3.

[0028] The roller shutter assembly 6 includes a rectangular block 61 fixedly installed on the front side of the inner cavity of the greenhouse body 1 near both sides, and a support block 62 fixedly installed on one side of the rectangular block 61. A servo motor A63 is fixedly installed at the bottom of the support block 62. A round rod 64 is movably inserted through the opposite side of the rectangular block 61, and the power output shaft of the servo motor A63 is fixedly connected to the adjacent round rod 64. A movable block 65 is provided on the opposite side of the round rod 64 (and the other end of the round rod 64 is fixedly connected to the adjacent movable block 65). A locking block 66 is provided on the opposite side of the movable block 65. A winding roller 67 is provided on the opposite side of the movable block 65. A shielding curtain 68 is wrapped around the outer periphery of the winding roller 67, and a T-shaped counterweight 69 is fixedly installed at the bottom of the shielding curtain 68. The bottom of the T-shaped counterweight 69 is located in the inner cavity of the U-shaped block 4. A slot is opened on the opposite side of the winding roller 67, and the locking blocks 66 are respectively movably inserted into the inner cavity of the adjacent slot.

[0029] A toggle block 651 is fixedly installed on the top of the movable block 65 on the other side. A reset telescopic rod 652 is fixedly installed on the other side of the movable block 65 near the top and bottom. A connecting block 654 is fixedly installed on the other end of the reset telescopic rod 652. One side of the connecting block 654 is fixedly connected to the adjacent round rod 64. A reset spring 653 is movably sleeved on the outer periphery of the reset telescopic rod 652. The two ends of the reset spring 653 are fixedly connected to the connecting block 654 and the movable block 65, respectively.

[0030] Specifically, when it is necessary to disassemble the take-up roller 67, the movable block 65 fixed on the movable block 651 can be moved to the other side by pushing the actuating block 651 to the other side, thereby squeezing the reset telescopic rod 652 and the reset spring 653, and making the locking block 66 fixed on the movable block 65 move away from the inner cavity of the locking slot, which facilitates the disassembly of the take-up roller 67.

[0031] The top of the T-shaped counterweight 69 is movably connected to the limit rods 691 near both sides, and the bottom of the limit rods 691 is fixedly connected to the bottom of the inner cavity of the greenhouse body 1. The two sides of the T-shaped counterweight 69 are provided with slots near the bottom. The outer periphery of the limit rods 691 is provided with external threads near the top, and the outer periphery of the limit rods 691 is threaded with nuts 692 near the top.

[0032] Specifically, the T-shaped counterweight 69 can be limited when it moves by the limiting rod 691, and the T-shaped block 69 can be removed as a whole by removing the nut 692 that is threaded onto the limiting rod 691, which facilitates the subsequent removal of the T-shaped block 69 and the subsequent disassembly and replacement of the curtain 68.

[0033] Example 2

[0034] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 3 , Figure 4 and Figure 6 The limiting component 7 includes a servo motor B71 fixedly installed on the other side of the inner cavity of the groove 5 and a threaded rod 72 fixedly installed on the power output shaft end of the servo motor B71. The outer periphery of the threaded rod 72 has opposite threads near both ends. One end of the threaded rod 72 is rotatably connected to one side of the inner cavity of the groove 5. The outer periphery of the threaded rod 72 is threadedly connected to both ends with threaded sleeves 73. The front side of each threaded sleeve 73 is fixedly installed with a bent rod 74, and the opposite end of each bent rod 74 is fixedly installed with an insert 75. The opposite side of the insert 75 is movably inserted into the inner cavity of the adjacent slot.

[0035] Specifically, when the T-shaped counterweight 69 is located in the inner cavity of the U-shaped block 4, with the cooperation of the limiting component 7, the threaded sleeve 73, which is threaded to the outer circumference of the threaded rod 72, can move to the opposite side, thereby allowing the insert 75 to be inserted into the inner cavity of the adjacent slot, which can limit the T-shaped counterweight 69, prevent the curtain 68 from being blown open by the wind, and improve the protective effect on plants in the agricultural greenhouse.

[0036] Each threaded sleeve 73 has a fixed block 731 fixedly installed at its bottom, and a crossbar 732 is provided through one side of the fixed block 731. The two ends of the crossbar 732 are fixedly connected to the inner cavity sidewall of the groove 5.

[0037] Specifically, by setting the fixing block 731 and the crossbar 732, the movement of the threaded sleeve 73 can be limited, thereby improving the stability of the threaded sleeve 73 during movement.

[0038] It should be noted that both servo motor A63 and servo motor B71 are electrically connected to an external power source.

[0039] Working Principle: When using this invention, if the curtain 68 needs to be rolled up, the operator can start the servo motor B71 via the controller. The rotation of the power output shaft of the servo motor B71 drives the threaded rod 72 fixed to the end of the power output shaft of the servo motor B71 to rotate. This causes the threaded sleeve 73, which is threaded to the outer circumference of the threaded rod 72, to move to the opposite side under the limitation of the fixed block 731 and the crossbar 732. Through the connection of the bent rod 74 fixed on the threaded sleeve 73, the insert 75 can be moved to the opposite side, away from the inner cavity of the adjacent slot. Conversely, the insert 75 can be inserted into the inner cavity of the adjacent slot. Inside the cavity, the T-shaped counterweight can be positioned to prevent the curtain 68 from being blown open by the wind, thus improving the protection of plants inside the agricultural greenhouse. When the curtain 68 is rolled up, the servo motor A63 can be started by the controller. The rotation of the power output shaft of the servo motor A63 drives the adjacent round rod 64 fixed at the end of the power output shaft of the servo motor A63 to rotate, which in turn causes the adjacent movable block 65 to rotate. Under the rotation of the movable block 65, the winding roller 67 can rotate, which in turn rolls up the curtain 68 located on the outer periphery of the winding roller 67, preventing the curtain 68 from hanging down and improving the efficiency of transporting items inside the agricultural greenhouse.

[0040] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
