Description

Technical Field

[0001] The utility model relates to the technical field of deformable greenhouses, and specifically relates to a deformable greenhouse. Background Art

[0002] A deformable greenhouse is an agricultural facility with a flexible structural design that can be dynamically adjusted according to different environmental conditions and crop requirements. In order to adjust the solar irradiation intensity inside the greenhouse, in a general deformable greenhouse, the support frame is fixed on the ground, and a transparent film is covered on the fixed frame to protect the crops inside the greenhouse. Then, a sunshade cloth that is convenient for retracting and extending is arranged inside or outside the transparent tarpaulin to adjust the solar irradiation intensity inside the greenhouse. Most deformable greenhouses on the market fold and store the sunshade cloth in a wavy folding manner. This storage method makes the crease of the sunshade cloth more likely to be damaged compared to the non-crease part, shortening the service life of the tarpaulin.

[0003] Based on this, a deformable greenhouse is now provided, which can eliminate the drawbacks of the existing device. Content of the Utility Model

Detailed implementation manners

[0021] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments.

[0022] In one embodiment, as Figures 1 - 4 shown, a deformable greenhouse includes two support frames 101 arranged on the ground. The two support frames 101 are connected by a connecting rod 102. A transparent tarpaulin 103 is arranged outside the support frame 101, and the transparent tarpaulin 103 is fixedly connected to the connecting rod 102. A mounting seat 201 is arranged at the top of the support frame 101. A rotating roller 202 is rotatably penetrated through the mounting seat 201. Two sunshade tarpaulins 203 are wound on the rotating roller 202. One end of the rotating roller 202 is connected to a driven gear 206. A driving assembly for driving the driven gear 206 is arranged on the mounting seat 201. A counterweight assembly for driving the free end of the sunshade tarpaulin 203 to move is arranged on the support frame 101.

[0023] In this embodiment, when storing the sunshade tarpaulin 203, the driving assembly rotates the rotating roller 202 counter - clockwise to wind the sunshade tarpaulin 203 on the rotating roller 202. When using the sunshade tarpaulin 203, the driving assembly rotates the rotating roller 202 clockwise. With the cooperation of the counterweight assembly, the free end of the sunshade tarpaulin 203 moves downward to block the sunlight.

[0024] In one embodiment, as Figure 1 and Figure 2As shown in the figure, the driving assembly includes a driving motor mounting plate 402 disposed on the right side surface of the mounting base 201. A driving motor 401 is provided on the upper surface of the driving motor mounting plate 402. The power output end of the driving motor 401 is connected to a driving shaft 403. A friction plate 404 is provided at the right end of the driving shaft 403. A fixing column 405 is provided on the right end surface of the friction plate 404. The fixing column 405 is coaxial with the driving shaft 403. A driving gear 406 is rotatably provided coaxially on the fixing column 405. The left end surface of the driving gear 406 is in contact with the right end surface of the friction plate 404. A limiting ring 407 is slidably provided near the right end of the fixing column 405. A locking bolt 408 is threadedly connected through the limiting ring 407. The threaded end of the locking bolt 408 contacts the fixing column 405. A spring 409 in a compressed state is provided between the driving gear 406 and the limiting ring 407. The driving gear 406 meshes with the driven gear 206. The driving motor 401 drives the driving shaft 403 to rotate. The driving shaft 403 drives the friction plate 404 and the fixing column 405 to rotate. The spring 409 presses the driving gear 406 tightly against the friction plate 404. The driving gear 406 rotates synchronously with the friction plate 404. The driving gear 406 drives the driven gear 206 to rotate, so as to drive the rotating roller 202 to rotate. When the rotating roller 202 is stuck and unable to rotate during the winding of the sunshade cloth 203, the frictional force between the friction plate 404 and the driving gear 406 is not sufficient to support the driving gear 406 to forcibly drive the driven gear 206, and a slipping phenomenon occurs between the driving gear 406 and the friction plate 404, protecting the driving assembly and the sunshade cloth 203 from damage. By adjusting the position of the limiting ring 407 on the fixing column 405, the pressure of the spring 409 on the driving gear 406 is adjusted, and the frictional force between the friction plate 404 and the driving gear 406 is changed.

[0025] In one embodiment, as Figure 3 shown, the counterweight assembly includes a counterweight rod 205 connected to the free end of the sunshade cloth 203. Both ends of the counterweight rod 205 are slidably disposed in the sliding grooves 204. The sliding grooves 204 are provided on the opposite surfaces of the two support frames 101. The counterweight rod 205 slides in the sliding grooves 204, driving the free end of the sunshade cloth 203 to move downward to block the sunlight.

[0026] In one embodiment, as Figure 4 shown, a fixing sleeve 301 is connected to the end of the sliding groove 204. A rotating sleeve 302 is provided outside the fixing sleeve 301. A rotating groove 303 is provided between the fixing sleeve 301 and the rotating sleeve 302. A ball 304 is rollably provided in the rotating groove 303. The rotating sleeve 302 is in contact with the sliding groove 204, reducing the frictional resistance when the counterweight rod 205 moves in the sliding groove 204 and facilitating the retraction and extension of the sunshade cloth 203.

[0027] In one embodiment, as Figure 1 shown, the support frame 101 is made of galvanized steel pipes welded together, and the connecting rod 102 is a galvanized steel pipe, which has high strength, is not easy to rust, and has good durability.

[0028] In one embodiment, as Figure 1 shown, the support frame 101 and the connecting rod 102 are connected by bolts, without welding, and the installation is convenient and fast.

[0029] In one embodiment, as Figure 1 shown, the sunshade cloth 203 is woven from polypropylene fibers, which has high strength, strong anti-aging and anti-ultraviolet capabilities, and a long service life.

[0030] The above embodiment discloses a deformable greenhouse. When the sunshade cloth 203 is stored, the driving motor 401 drives the driving shaft 403 to rotate clockwise. The driving shaft 403 drives the friction plate 404 and the fixed column 405 to rotate clockwise. The spring 409 presses the driving gear 406 tightly against the friction plate 404. The driving gear 406 rotates synchronously with the friction plate 404. The driving gear 406 drives the driven gear 206 to rotate counterclockwise. The driven gear 206 drives the rotating roller 202 to rotate counterclockwise, so that the sunshade cloth 203 is wound around the rotating roller 202. When using the sunshade cloth 203, the driving motor 401 rotates counterclockwise, and finally drives the rotating roller 202 to rotate clockwise to release the sunshade cloth 203. Under the action of the gravity of the counterweight rod 205, the counterweight rod 205 slides in the sliding groove 204 to drive the free end of the sunshade cloth 203 to move downward to block the sunlight. When the rotating roller 202 winds the sunshade cloth 203 and abnormal situations such as the rotating roller 202 being stuck and unable to rotate occur, the friction between the friction plate 404 and the driving gear 406 is not enough to support the driving gear 406 to forcibly drive the driven gear 206, and the driving gear 406 slips relative to the friction plate 404, protecting the driving assembly and the sunshade cloth 203 from damage. By adjusting the position of the limit ring 407 on the fixed column 405, the pressure of the spring 409 on the driving gear 406 is adjusted, and the friction between the friction plate 404 and the driving gear 406 is changed.

[0031] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present application, and all should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
