Description

Technical Field

[0001] The utility model relates to the technical field of agricultural greenhouses, in particular to a greenhouse bracket. Background Art

[0002] Greenhouses have a large coverage area, large space, good thermal effect, are easy to build, and have a low cost. They are currently the most widely used vegetable production facilities. Among them, multi-span greenhouses have the advantages of high land area utilization, large overall space span, good thermal insulation effect, and convenient internal unified management. They have been widely promoted in northern my country. Patent document with application number CN202323162247.7 discloses a hilly multi-span greenhouse with a fully open top and automatic film roll. It has a water trough at each end of the top rod, which is conducive to drainage of the low-lying area between the two large greenhouse units. However, its water trough is connected to the outside of the roof, which is prone to water seepage in rainy weather. Moreover, after rainy weather, the film near the water trough is prone to water accumulation and deformation, affecting the covering effect of the film. Utility Model Content

[0003] In order to solve the technical problems in the above background technology that the connection points of multi-span greenhouses are prone to water seepage and the film at the connection points is prone to water accumulation and deformation, the utility model provides a greenhouse bracket.

[0004] The technical solution of this utility model is as follows:

[0005] A greenhouse support comprises a plurality of top frames arranged in parallel, wherein the top frames comprise a plurality of arched rods arranged in parallel and with openings facing downward, and a support frame is further provided between two adjacent top frames; the support frame comprises a vertically arranged support rod, above which a strip-shaped connecting beam is provided along the length direction of the top frame, and the upper side of the connecting beam is provided with a water collecting groove passing through both ends thereof along the length direction; two strip-shaped connecting plates are provided opposite to each other on both sides of the upper part of the connecting beam along the length direction, and the arched rod is close to one end of the support frame and is clamped and connected to the inner side of the connecting plate close thereto.

[0006] Several top frames are connected by support frames, each equipped with a drainage groove. The entire structure integrates drainage and support functions, eliminating the need for additional drainage gutters after the greenhouse is built. Furthermore, the connecting beams are connected to the arched rods via connecting plates, which are positioned between the two connecting plates. This prevents rainwater from seeping into the greenhouse through the gap between the arched rods and the connecting plates. Furthermore, the film adheres to the connecting plates under the action of rainwater, preventing deformation and extending its service life.

[0007] Furthermore, the inner sides of the two connecting plates are each provided with an arc-shaped fixing groove capable of engaging with the end of the arch rod close to the support frame. The arc-shaped fixing groove can better match the bending curvature of the arch rod, thereby enhancing the limiting and fixing effect of the arch rod.

[0008] Preferably, first pressing grooves are provided along the length of both sides of the groove to press the film into. The first pressing grooves allow the film to be tightened and trimmed, and the film of the entire greenhouse is provided separately. If the film on a top frame is damaged, its edge can be removed from the first pressing groove and subsequently replaced separately.

[0009] To enhance the connection between the arched rods and the film, several of the arched rods have a second pressing groove along their length, on the side facing away from the opening. This second pressing groove runs through both ends of the arched rods. After the film is laid, the film above the arched rods can be pressed into the second groove, securing and tensioning the film.

[0010] Further preferably, a plurality of support rods are provided along the length direction of the connecting beam, and the support rods correspond to the positions of the plurality of arch rods, so as to enhance the supporting effect of the support rods on the connecting beam and evenly share the pressure on the connecting beam.

[0011] As a preferred embodiment, the connecting beam is provided with a plurality of bayonet holes that cooperate with the upper ends of the support rods. After the support rods are installed on the ground, the connecting beam can be temporarily clamped on the upper ends of the support rods, and then the connecting beam and the support rods are fixedly connected.

[0012] To facilitate the smooth entry of rainwater, dust, fallen leaves, etc. into the groove, the two side walls of the groove are relatively inclined, that is, the size of the upper opening of the groove along the direction perpendicular to the length of the groove is larger than the size of the bottom surface of the groove along the direction perpendicular to the length of the groove.

[0013] Further preferably, a fixing member is connected between the lower side of the connecting beam and the support rod; a plurality of fixing members are provided along the circumference of the outer ring of the support rod. One side of the fixing member is fixedly connected to the lower side of the connecting beam, and the other side is fixedly connected to the outer ring of the support rod, which can increase the connection area between the connecting beam and the support rod and improve overall stability.

[0014] Through the above design, the beneficial effects of the greenhouse bracket of the utility model are:

[0015] (1) The support frame not only connects and supports several top frames, but also has the function of collecting water, so there is no need to add a drainage gutter after the greenhouse is built.

[0016] (2) The connecting plate is connected to the opening side of the arch frame to prevent rainwater from seeping into the greenhouse through the connecting gap.

[0017] (3) The connecting plates arranged along the length direction of the top frame can support the film. The film can stick to the connecting plates under the action of rainwater, thus avoiding deformation of the film and increasing its service life. BRIEF DESCRIPTION OF THE DRAWINGS

The first pressing grooves 15 can be provided to tighten and trim the film, and the film of the entire greenhouse is provided separately. When the film on a certain top frame 2 is damaged, its edge can be removed from the first pressing grooves 15 and then replaced separately.

[0038] A corrugated strip 4 is movably provided in the first groove to press the film into the first groove. Two opposite side walls of the first groove are provided with clamping grooves along the length direction thereof. The corrugated strip 4 can be clamped between the two clamping grooves.

[0039] To facilitate the smooth entry of rainwater, dust, fallen leaves, etc. into the groove, the two side walls of the groove are relatively inclined, that is, the size of the upper opening of the groove along the direction perpendicular to the length of the groove is larger than the size of the bottom surface of the groove along the direction perpendicular to the length of the groove.

[0040] In this embodiment, two strip-shaped connecting plates 13 are provided on opposite sides of the upper portion of the connecting beam 12 along its length. The arched rod 21 is located near the end of the support frame 1 and is snap-connected to the inner side of the connecting plates 13 adjacent thereto. The arched rod 21 is positioned between the two connecting plates 13, preventing rainwater from seeping into the greenhouse through the gap between the arched rod 21 and the connecting plates 13.

[0041] Combine Figure 3 Furthermore, the inner sides of the two connecting plates 13 are each provided with an arc-shaped fixing groove 14 that can be engaged with the end of the arch rod 21 close to the support frame 1. The arc-shaped fixing groove 14 can better match the bending curvature of the arch rod 21, thereby enhancing the limiting and fixing effect of the arch rod 21.

[0042] The arch rod 21 is fixed in the fixing groove 14 by bolts, and a sealing rubber strip is provided on the side of the fixing groove 14 facing the arch rod 21, which can prevent water vapor or dew inside the greenhouse from penetrating into the fixing groove 14, avoid erosion of components such as bolts, reduce the possibility of rust on the bolts, and improve the service life.

[0043] The support frame 1 of this greenhouse support not only connects and supports the top frames 2 but also functions as a drainage system, eliminating the need for additional drainage gutters after the greenhouse is constructed. The connecting plates 13 connect to the open sides of the arched frames to prevent rainwater from seeping into the greenhouse through the connecting gaps. The connecting plates 13, positioned along the length of the top frames 2, support the film, allowing it to adhere to the connecting plates 13 under the influence of rainwater, preventing deformation and increasing its service life.
