Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, specifically to an agricultural rain shelter. Background Technology

[0002] In existing technology, the structure of a rain shelter for crops (vegetables, fruit trees, etc.) includes several arched standard film supports arranged at intervals along the length of the rain shelter. Sliding tracks are attached to the top center and both sides of each standard film support, and flexible rain-proof film is installed between adjacent tracks. The flexible rain-proof film is connected to sliding components within the tracks on both sides, allowing it to slide along the guide rails. When it rains, the flexible rain-proof film is fully unfolded to provide rain protection. When the weather is sunny, to allow the crops to receive sunlight, the flexible rain-proof film is folded back to the side closest to the outermost standard film support. Even after folding, the flexible rain-proof film still has a certain area. In existing technology, the folded rain-proof film is located above the crops, which blocks sunlight, preventing some of the crops below from receiving sufficient sunlight and affecting their growth. Furthermore, since the flexible rain-proof film is folded back to the higher standard film support, it is difficult to protect against the elements, ages quickly under wind and sun, and is easily damaged. If damage occurs, operators need to use ladders to reach the roof for replacement, which is very inconvenient and poses a safety hazard. Utility Model Content

[0003] The purpose of this invention is to provide an agricultural rain shelter that addresses the problem that in existing agricultural rain shelters, the flexible rain-shielding film, when folded up, sits above the crops and blocks sunlight, preventing some of the crops below from receiving sufficient sunlight and thus affecting their growth.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An agricultural rain shelter includes a film-collecting support frame and at least two standard film supports arranged longitudinally at intervals; the height of the film-collecting support frame is less than the height of the standard film supports; it also includes at least two guide rails, both longitudinally arranged, which are laterally spaced and fixedly overlap the tops of the standard film supports and the film-collecting support frame; a sliding member is slidably installed on any of the guide rails; a flexible rain-proof film is provided between any two adjacent guide rails, and the opposite sides of any one of the flexible rain-proof films are respectively connected to the sliding member in the adjacent guide rail; the flexible rain-proof film can slide with the sliding member to fold into one side of the film-collecting support frame.

[0006] The present invention, employing the aforementioned technical solution, adds a film-retracting bracket to one end of the standard film support. When it rains, the flexible rain-proof film is fully unfolded above the standard film support to provide shelter from the rain. When the weather is sunny, the flexible rain-proof film is slidably folded to one side of the film-retracting bracket. Since the crops are located between the standard film supports, the folded flexible rain-proof film will not block the sunlight reaching the crops. Compared to the existing technology where the folded flexible rain-proof film on the crop rain shelter is located above the crops, blocking sunlight and causing some crops below to not receive sufficient sunlight, thus affecting crop growth, the flexible rain-proof film of the present invention is folded to one side of the film-retracting bracket, not above the crops, and will not block sunlight, ensuring that all crops receive sufficient sunlight and resulting in better growth.

[0007] Furthermore, the top of the film-retracting bracket is less than or equal to 1 meter from the ground. With this configuration, after the flexible rainproof film is folded to one side of the film-retracting bracket, it is very close to the ground. Operators can stand on the ground to cover the folded flexible rainproof film with a protective layer to prevent wind and sun exposure and slow down the aging of the rainproof film. If the flexible rainproof film is damaged and needs to be replaced, operators can also complete the replacement while standing on the ground, making the operation more convenient and eliminating safety hazards.

[0008] Furthermore, the top center of the standard membrane support is higher than the top sides; the guide rail includes a middle guide rail and two side guide rails, the middle guide rail is fixedly connected to the top center of the standard membrane support and the film collection support, and the two side guide rails are respectively fixedly connected to the top sides of the standard membrane support and the film collection support; with this arrangement, rainwater will not accumulate on the rain shelter.

[0009] Furthermore, the intermediate guide rail is provided with a first U-shaped groove along its length, and a first sliding member is slidably embedded in the first U-shaped groove; the side guide rail is provided with a second U-shaped groove along its length, and a second sliding member is slidably embedded in the second U-shaped groove; each of the opposite sides of the flexible rainproof film is respectively hooked to the first sliding member and the second sliding member by hooks; the two sides of the flexible rainproof film are hooked to the first sliding member and the second sliding member by hooks, and the hook connection facilitates installation and disassembly.

[0010] Furthermore, the first sliding member includes multiple first sliding trolleys slidably installed within the first U-shaped groove, with a chain connecting any two adjacent first sliding trolleys; the second sliding member includes multiple second sliding trolleys slidably installed within the second U-shaped groove; multiple spaced first connecting holes and second connecting holes are respectively provided on opposite sides of any of the flexible rainproof films, and a first hook is attached to any first connecting hole and the chain; each second sliding trolley corresponds one-to-one with a second connecting hole, and a second hook is fixedly installed on any second sliding trolley, with the second hook hooked into the second connecting hole; with this arrangement, the sliding of the flexible rainproof film is more stable when unfolding and folding.

[0011] Furthermore, any of the standard membrane supports is arched, comprising multiple uprights and a first top rod; the multiple uprights are arranged at intervals along the lateral direction; the first top rod is arched and is fixedly attached to the top of the uprights; with this arrangement, rainwater will not accumulate on the rain shelter, and the arched top rod has good stress resistance and can withstand the impact of heavy rain, making the overall structure of the rain shelter stable.

[0012] Furthermore, the film collection support includes multiple uprights and a second top rod; the multiple uprights are arranged at intervals along the lateral direction; the second top rod is in the shape of an I-shaped rod and is fixedly attached to the top of the uprights; the film collection support has a simple structure and is easy to install.

[0013] Furthermore, any of the aforementioned standard membrane support structures is pointed in shape, comprising a central upright, two side uprights, two cables, and two sleeves; the two side uprights are respectively arranged on both sides of the central upright; the height of the side uprights is less than the height of the central upright; two cables are respectively connected between the top of the central upright and the tops of the two side uprights; the two sleeves are respectively fitted onto the outside of the two cables, and each sleeve can rotate around the cable inside it; with this configuration, when the flexible rainproof membrane slides with the sliding member, it rubs against the sleeve, causing the sleeve to rotate. Compared to the standard support frame with a fixed top rod structure, the friction between the flexible rainproof membrane and the sleeve is significantly reduced, thereby reducing the wear of the flexible rainproof membrane.

[0014] Furthermore, a diagonal brace is provided between the standard membrane support and the film receiving support; the diagonal brace is inclined toward the film receiving support, and its height is less than the height of the standard membrane support but greater than the height of the film receiving support; the guide rails are all fixedly attached to the top of the diagonal brace; the distance between the standard membrane support and the film receiving support is relatively long, and the diagonal brace is provided to support the middle guide rail and the side guide rail, reducing the deformation caused by the self-weight of the guide rail and the swaying amplitude caused by wind.

[0015] Compared to existing technologies, the advantages of this invention are as follows: the flexible rain-proof film folds down to one side of the film-collecting bracket, not above the crops, thus not blocking sunlight and ensuring that the crops receive sufficient sunlight for better growth; after folding down to one side of the film-collecting bracket, the flexible rain-proof film is very close to the ground, allowing operators to stand on the ground to cover the folded flexible rain-proof film with a protective layer, preventing wind and sun exposure and slowing down the aging of the rain-proof film; if the flexible rain-proof film is damaged and needs to be replaced, the operator can also complete the replacement while standing on the ground, making the operation more convenient and eliminating safety hazards.

Addressing the issue of sunlight affecting crop growth, this new flexible rain-proof film folds down to one side of the support frame, away from the crops, ensuring ample sunlight exposure and optimal growth. Furthermore, the folded film is very close to the ground, allowing operators to stand on the ground to apply a protective layer, preventing wind and sun damage and slowing down aging. If the film is damaged and needs replacement, the operator can also complete the replacement while standing on the ground, making the process more convenient and eliminating safety hazards.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
