Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural technology, specifically to an agricultural rain shelter. Background Technology
[0002] In the prior art, the structure of a rain shelter for crops (vegetables, fruit trees, etc.) includes several supports arranged at intervals along the length of the rain shelter. Multiple parallel connecting rods are provided between the tops of the supports, and a flexible rain-proof membrane is installed between the connecting rods. In the prior art, when encountering windy and rainy weather, the flexible rain-proof membrane is prone to bulging upward or sinking downward under the impact of wind or rain. Large deformation can easily lead to damage to the flexible rain-proof membrane, making it unable to achieve the function of rain protection. Utility Model Content
[0003] The purpose of this invention is to address the problem that in the existing technology, the flexible rain-shielding film on agricultural crop rain shelters is prone to bulging upwards or sinking downwards under the impact of wind or rain, and the large deformation can easily lead to damage to the flexible rain-shielding film, thus failing to achieve the purpose of rain protection. This invention provides an agricultural rain shelter.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] An agricultural rain shelter includes a flexible rain-shielding film and at least two supports arranged at intervals. Each support has a "U"-shaped limiting frame at its top. The limiting frame includes an upper top rod and a lower top rod arranged at intervals, forming a strip-shaped gap between them. It also includes a first support rod and a second support rod, both arranged along the length of the rain shelter, both passing through the gap in any support and fixedly connected to both ends of the limiting frame. The flexible rain-shielding film passes through the gap in any support, and its opposite ends are connected to the first and second support rods, respectively. A taut first limiting net is provided between the upper top rods of any two adjacent supports, and a taut second limiting net is provided between the lower top rods of any two adjacent supports.
[0006] The present invention, employing the aforementioned technical solution, sets a limiting frame structure at the top of the support frame, placing the flexible rain-shielding film and the first and second support rods that support the flexible rain-shielding film within the limiting frame. This allows the flexible rain-shielding film to be positioned between the first and second limiting nets. During windy and rainy weather, the taut first limiting net can prevent the flexible rain-shielding film from bulging, and the taut second limiting net can prevent the flexible rain-shielding film from denting, thus preventing excessive deformation and damage. Compared to the existing technology where the flexible rain-shielding film on agricultural rain shelters easily bulges upward or dents downward under the impact of wind or rain, and large deformations can easily lead to damage and failure to provide rain protection, the present invention limits the flexible rain-shielding film by setting the first and second limiting nets, preventing large deformations and thus avoiding damage.
[0007] Furthermore, both the first and second limiting nets are square grid nets; this configuration ensures a more balanced blocking and limiting effect of the first and second limiting nets on the flexible rainproof film.
[0008] Furthermore, any of the brackets is pointed, comprising two inclined limiting frames, which are symmetrically arranged and connected to each other to form a Λ-shaped structure. With this arrangement, rainwater is less likely to accumulate on the flexible rainproof film. Moreover, by forming a frame structure at the top of the bracket, its top structure has greater strength than the single top rod structure of the prior art, that is, the structure has a reinforcing effect on the top of the bracket.
[0009] Furthermore, both the first and second support rods are provided with sliding grooves along their length, and each of the two sliding grooves is provided with multiple sliding elements arranged at intervals, with each sliding element having a hook; a row of spaced-apart connecting holes are opened on opposite sides of the flexible rainproof film; the hooks are hooked into the connecting holes one by one; with this arrangement, in sunny weather, the flexible rainproof film can slide with the sliding elements to fold up to one side of the top of the rainproof canopy, avoiding blocking sunlight and benefiting crop growth.
[0010] Furthermore, both the first and second support rods are C-shaped tubular structures, and the sliding element is a ball bearing installed inside the tube hole of the tubular structure; the hook on the ball bearing extends out of the notch of the tubular structure and is hooked into the connection hole of the flexible rainproof film; with this configuration, the structure of the support rod and the sliding element is simple and easy to manufacture.
[0011] Furthermore, each of the aforementioned balls is provided with a threading hole; a first metal wire is provided inside the first support rod, and the balls inside the first support rod are all threaded through the threading hole onto the first metal wire; a second metal wire is provided inside the second support rod, and the balls inside the second support rod are all threaded through the threading hole onto the second metal wire; the balls are strung together by the metal wire, which facilitates the insertion or removal of multiple balls into or out of the support rod. At the same time, the metal wire also restricts the rotation of the balls inside the support rod.
[0012] Furthermore, the end of the first limiting net is tied to the first top rod with a rope, and the end of the second limiting net is tied to the second top rod with a rope; the binding connection between the limiting net and the top rod is firm and easy to implement.
[0013] Furthermore, any two adjacent supports are connected by several connecting rods, with any connecting rod arranged along the length of the rain shelter; the connecting rods enhance the strength and stability of the overall frame structure of the rain shelter.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting the first limiting net and the second limiting net to limit the flexible rainproof film, the flexible rainproof film is prevented from undergoing large deformation, thereby avoiding damage to the flexible rainproof film; by forming a frame structure at the top of the support, compared with the single top rod structure of the prior art, its top structure has greater strength, that is, the structure has a reinforcing effect on the top of the support.

The number of supports 2 is determined according to the distance between the supports 2 and the length of the agricultural shed. In this embodiment, two supports 2 are selected;
[0026] The top of any support 2 forms a "mouth" - shaped limit frame. The limit frame includes an upper top rod 21 and a lower top rod 22 arranged at intervals up and down, and a strip - shaped gap 23 is formed between the two; it also includes a first support rod 3 and a second support rod 4 both arranged along the length direction of the rain shelter. Both of them pass through the gap 23 of any support 2, and are respectively fixedly connected to both ends of the limit frame; the flexible rain shelter film 1 passes through the gap 23 of any support 2, and the opposite ends of the flexible rain shelter film 1 are respectively connected to the first support rod 3 and the second support rod 4; a tightened first limit net 5 is provided between the upper top rods 21 of any two adjacent supports 2, and a tightened second limit net 6 is provided between the lower top rods 22 of any two adjacent supports 2; both the first limit net 5 and the second limit net 6 are square grid nets; in this embodiment, a L - shaped connection plate 12 is respectively fixed at both ends of the lower top rod 22, and the first support rod 3 and the second support rod 4 are respectively fixedly connected to the two connection plates 12;
[0027] The support 2 can be flat-topped, only including a horizontally arranged limiting frame. At this time, the upper top rod 21 and the lower top rod 22 are horizontally arranged, and a flexible rain shelter film 1 is inserted into the gap 23 between the upper top rod 21 and the lower top rod 22 for shielding the bottom crops; in this embodiment, in order for the support 2 to have a better stress effect, any support 2 is set to be spire-shaped, which includes two obliquely arranged limiting frames. The two limiting frames are symmetrically arranged and connected to each other, forming an overall Λ-shaped structure, so that there is a flexible rain shelter film 1, a first support rod 3, a second support rod 4, a first limiting net 5 and a second limiting net 6 on the left and right sides of the top of this rain shelter respectively;
[0028] The support 2 is spliced by two symmetrically arranged support components. Any support component includes a vertical rod 24, a horizontal rod 25, a vertical rod 26, an upper top rod 21 and a lower top rod 22. One end of the horizontal rod 25 is connected to the top of the vertical rod 24, and the other end of the horizontal rod 25 is connected to the bottom of the vertical rod 26; the upper top rod 21 and the lower top rod 22 are parallel and both obliquely arranged. One end of the upper top rod 21 and the lower top rod 22 is connected to the top of the vertical rod 26, and the other end is connected to the top of the vertical rod 24; the top of the vertical rod 26, the top of the vertical rod 24, the upper top rod 21 and the lower top rod 22 enclose a "mouth"-shaped limiting frame; several diagonal braces are connected between the horizontal rod 25 and the lower top rod 22 to increase the structural strength;
[0029] The connection method between the flexible rain shelter film 1 and the first support rod 3 and the second support rod 4 can be fixed connection or sliding connection. In this embodiment, sliding connection is selected. Specifically: both the first support rod 3 and the second support rod 4 are provided with chutes along the length direction, and a plurality of sliding members arranged at intervals are provided in both chutes. A hook 8 is provided on any sliding member; a row of connection holes 11 arranged at intervals are opened on the opposite side edges of the flexible rain shelter film 1; the hooks 8 are hung in the connection holes 11 one by one;
[0030] The specific structure of the sliding member is not limited. For example, it can be a sliding trolley embedded in the chute. In this embodiment, the sliding member is a ball. Both the first support rod 3 and the second support rod 4 are tubular structures with a C-shaped cross-section, and the sliding member is a ball 7 installed in the tube hole of the tubular structure; the hook 8 on the ball 7 extends out of the notch of the tubular structure and is hung in the connection hole 11 of the flexible rain shelter film 1;
[0031] Each ball bearing 7 is provided with a threading hole 71; a first steel wire 9 is provided inside the first support rod 3, and the balls bearing 7 inside the first support rod 3 are all threaded through the threading hole 71 onto the first steel wire 9; a second steel wire 10 is provided inside the second support rod 4, and the balls bearing 7 inside the second support rod 4 are all threaded through the threading hole 71 onto the second steel wire 10; the balls bearing 7 are provided with mounting holes 72 that are perpendicular to but do not intersect with the threading holes 71, for mounting hooks 8. The hook 8 includes a hook part and a straight rod part connected together. The hook part is hooked into the connecting hole 11, and the straight rod part is inserted into the mounting hole 72. Its end extends out of the mounting hole 72 and is threadedly connected to a nut. The nut is used to limit the movement and prevent it from falling out of the balls bearing 7.
[0032] The end of the first limiting net 5 is tied to the first top rod 21 by a rope, and the end of the second limiting net 6 is tied to the second top rod 22 by a rope.
[0033] Any two adjacent supports 2 are connected by several connecting rods 13, and any connecting rod 13 is set along the length of the rain shelter.
[0034] The present invention, employing the aforementioned technical solution, sets a limiting frame structure at the top of the bracket 2, placing the flexible rainproof film 1 and the first support rod 3 and second support rod 4, which support the flexible rainproof film 1, within the limiting frame. This allows the flexible rainproof film 1 to be positioned between the first limiting net 5 and the second limiting net 6. In windy and rainy weather, the taut first limiting net 5 can prevent and limit the bulging of the flexible rainproof film 1, and the taut second limiting net 6 can prevent and limit the concavity of the flexible rainproof film 1, thus preventing excessive deformation of the flexible rainproof film 1 and potential damage. Compared to existing technologies where flexible rain-shielding films on crop rain shelters are prone to bulging upwards or sinking downwards under the impact of wind or rain, and large deformations can easily damage the flexible rain-shielding film and render it unable to provide rain protection, this utility model limits the flexible rain-shielding film by setting a first limiting net and a second limiting net, preventing large deformations and thus avoiding damage to the flexible rain-shielding film; by forming a frame structure at the top of the support, compared to the single top rod structure of existing technologies, its top structure has greater strength, that is, this structure has a reinforcing effect on the top of the support.
[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
