Description
An agricultural greenhouse with a winding mechanism Technical Field
[0001] This utility model relates to the field of agricultural greenhouse technology, specifically an agricultural greenhouse with a winding mechanism. Background Technology
[0002] An agricultural greenhouse is a protective facility used for crop growth. It creates a relatively enclosed and controlled growing environment for crops by constructing a frame and covering it with materials. Also known as a plastic film arched greenhouse, it is a protective structure made of materials such as bamboo, wood, steel, or steel pipes, supported by an arched or ridge-like frame and covered with a film. The overall shape of an agricultural greenhouse is similar to that of a medium or small greenhouse, but it has the largest area, typically occupying over 300 square meters. The height is 2–2.5 meters, with multi-span greenhouses exceeding 3 meters in height. The width or span is 8–15 meters, and the length varies from 30–60 meters.
[0003] Existing agricultural greenhouses use a film cover set up on multiple support frames to form a planting space. The greenhouse film has multiple holes, which not only does not affect the ventilation of the plants, but also prevents insects. Water and fertilizer can also be applied to the plants through the multiple holes in the greenhouse film, so watering and fertilization can be carried out from the outside of the agricultural greenhouse. However, in actual use, due to the large area occupied by the greenhouse, it is quite troublesome to open the outer film, and the film covering the outside of the greenhouse is difficult to roll up. Summary of the Invention
[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0005] Given the aforementioned or existing technologies, in actual use of greenhouses, due to the large area occupied by the greenhouse, it is quite troublesome to open the outer film, making it difficult to roll up the film covering the outside of the greenhouse.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An agricultural greenhouse with a winding mechanism includes a first fixing plate, a protective shell fixed horizontally on the inner wall of the first fixing plate, a second fixing plate fixed at the end of the protective shell, a winding mechanism for winding the film on the side wall of the first fixing plate, and a fixing mechanism for fixing the greenhouse below both the first fixing plate and the second fixing plate.
[0008] The winding mechanism includes a winding motor, which is fixed to the side wall of the first fixed plate by screws. The power output shaft of the winding motor passes through the first fixed plate and is fixed to a winding roller. The winding roller has a protective cavity inside the protective shell.
[0009] As a further embodiment of this utility model: two greenhouse films are fixed to the outer surface of the winding roller, and counterweight strips are fixed to the ends of the two greenhouse films.
[0010] As a further improvement of this utility model: both ends of the counterweight strip are fixed with limit blocks, and the limit blocks are externally slidably connected with limit grooves formed on the first fixed plate and the second fixed plate.
[0011] As a further improvement of this utility model, an electromagnet fixed to the inner wall of the limiting groove is movably connected to one side of the limiting block.
[0012] As a further improvement of this utility model: support rods are fixed horizontally on the inner walls of both the first fixing plate and the second fixing plate, and reinforcing frames are fixed at equal intervals on the outside of the support rods.
[0013] As a further embodiment of this utility model: the fixing mechanism includes a fixing seat, and there are two fixing seats, which are respectively fixed to the lower ends of the first fixing plate and the second fixing plate.
[0014] As a further improvement of this utility model: a positioning rod is fixed to the lower surface of each of the two fixed seats, and barbs are fixed to the outer wall of the positioning rod.
[0015] As a further improvement of this utility model: an observation window is embedded inside the first fixing plate, and a protective door is hinged to one side of the first fixing plate.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This utility model, by setting up a winding mechanism, can simultaneously wind up two greenhouse films, winding the two greenhouse films into the protective cavity, and the protective shell can play a protective role. In addition, the limiting block set on the counterweight strip, in cooperation with the limiting groove, plays a guiding role.
[0018] 2. By setting up a fixing mechanism, the positioning rod on the fixing seat can be inserted into the ground. With the cooperation of the barbs, the fixing seat can be limited, effectively reducing the displacement of the first fixing plate and the second fixing plate. Attached Figure Description

[0025] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this utility model. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments. Embodiments
[0028] Please refer to Figures 1-5, which are the first embodiments of this utility model. This embodiment provides an agricultural greenhouse with a winding mechanism, including a first fixing plate 1, a protective shell 2 fixed horizontally on the inner wall of the first fixing plate 1, a second fixing plate 3 fixed at the end of the protective shell 2, a winding mechanism for winding the film on the side wall of the first fixing plate 1, and a fixing mechanism for fixing the greenhouse on the bottom of both the first fixing plate 1 and the second fixing plate 3.
[0029] The winding mechanism includes a winding motor 4, which is fixed to the side wall of the first fixed plate 1 by screws. The power output shaft of the winding motor 4 passes through the first fixed plate 1 and a winding roller 41 is fixed thereon. The winding roller 41 has a protective cavity 42 opened inside the protective shell 2 on its exterior.
[0030] Specifically, two greenhouse films 43 are fixed to the outer surface of the winding roller 41, and counterweight strips 44 are fixed to the ends of the two greenhouse films 43.
[0031] Furthermore, the winding motor 4 drives the winding roller 41 to rotate. Since one end of the two greenhouse films 43 is fixed to the outer wall of the winding roller 41, the winding roller 41 can synchronously wind up the two greenhouse films 43 when it rotates.
[0032] Specifically, both ends of the counterweight strip 44 are fixed with limit blocks 45, and the limit blocks 45 are externally slidably connected with limit grooves 46 opened on the first fixed plate 1 and the second fixed plate 3.
[0033] Furthermore, in conjunction with the limiting groove 46, it can play a guiding role.
[0034] Specifically, one side of the limiting block 45 is movably connected to an electromagnet 47 fixed to the inner wall of the limiting groove 46.
[0035] Furthermore, when the electromagnet 47 is activated, it can attract the limit block 45, thereby preventing the counterweight strip 44 from shifting.
[0036] In use, first, place the first fixing plate 1 and the second fixing plate 3 in the appropriate positions. Then, start the winding motor 4 to drive the winding roller 41 to rotate. Since one end of each of the two greenhouse films 43 is fixed to the outer wall of the winding roller 41, the winding roller 41 can synchronously wind up the two greenhouse films 43 when it rotates, winding them into the protective cavity 42. The protective shell 2 can also provide protection. The limiting block 45 on the counterweight strip 44, in cooperation with the limiting groove 46, can guide the film and reduce the deviation of the greenhouse film 43 during winding. When the greenhouse film 43 needs to be put back, the winding motor 4 drives the winding roller 41 to reverse, thus putting the greenhouse film 43 back. The counterweight strip 44 ensures that the greenhouse film 43 can be smoothly put back down. After the greenhouse film 43 is put back, the electromagnet 47 is activated to attract the limiting block 45, thus preventing the counterweight strip 44 from shifting.
[0037] In summary, this agricultural greenhouse with a winding mechanism allows for convenient winding of the greenhouse film 43 without manual operation. Furthermore, after winding, the greenhouse film 43 is protected, reducing the risk of damage. Example
[0038] Please refer to Figures 1-5, which show the second embodiment of this utility model.
[0039] Specifically, support rods 5 are fixed horizontally on the inner walls of the first fixed plate 1 and the second fixed plate 3, and reinforcing frames 6 are fixed at equal intervals on the outside of the support rods 5. The fixing mechanism includes a fixing seat 7, and there are two fixing seats 7. The two fixing seats 7 are respectively fixed to the lower ends of the first fixed plate 1 and the second fixed plate 3.
[0040] Furthermore, the support rod 5 and the reinforcing frame 6 can enhance the overall strength of the first fixing plate 1 and the second fixing plate 3.
[0041] Specifically, positioning rods 71 are fixed to the lower surfaces of both fixing seats 7, and barbs 72 are fixed to the outer walls of the positioning rods 71.
[0042] Furthermore, the positioning rod 71 is inserted into the ground, and with the help of the barbs 72, it can limit the position of the fixing seat 7.
[0043] Specifically, an observation window 8 is embedded inside the first fixing plate 1, and a protective door 9 is hinged to one side of the first fixing plate 1.
[0044] Furthermore, the observation window 8 set on the first fixed plate 1 allows for easy observation of the inside of the greenhouse, and the protective door 9 facilitates entry into the greenhouse for planting.
[0045] In use, the first fixing plate 1 and the second fixing plate 3 can be fixed by the fixing seat 7 provided on the fixing plate 1 and the second fixing plate 3. The positioning rod 71 on the fixing seat 7 can be inserted into the soil. With the cooperation of the barbs 72, the fixing seat 7 can be limited, effectively reducing the displacement of the first fixing plate 1 and the second fixing plate 3. The observation window 8 provided on the first fixing plate 1 makes it easy to observe the situation inside the greenhouse. The protective door 9 can be opened to facilitate entry into the greenhouse for planting. When it is necessary to roll up the greenhouse film 43.
[0046] In summary, this agricultural greenhouse with a winding mechanism allows for convenient winding of the greenhouse film 43 without manual operation. After winding, the greenhouse film 43 is protected, reducing the risk of damage. Furthermore, the greenhouse can be easily secured during assembly, effectively reducing the possibility of subsequent displacement.
