Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural greenhouses, and particularly relates to a strong and collapse-proof agricultural cultivation greenhouse. Background Art

[0002] Agricultural greenhouses are widely used agricultural facilities in modern agriculture. They are mainly used to provide a suitable growth environment for crops to achieve the goals of early or delayed planting, improving yield and quality. There are various structural forms of greenhouses, the most common of which are arched and ridged. These structural forms are usually designed according to local climatic conditions, crop types and planting needs to ensure the stability and practicality of the greenhouse. Plastic film is widely used because of its low cost, good light transmittance and strong thermal insulation performance. In cold and severe weather conditions, a large amount of snow will accumulate on the top of the greenhouse, causing the greenhouse to collapse. The most prone to collapse is between the greenhouse frames. This part has no frame support and will form a depression. The accumulated snow will bend and deform the pull rod, causing economic losses. Utility Model Content

[0003] The utility model aims to provide a strong and collapse-proof agricultural cultivation greenhouse, so as to solve the problems that the tie rods between the greenhouse frames are weak in load-bearing capacity and are easily bent and deformed by accumulated snow, thus causing economic losses.

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1-4 As shown, in this embodiment, a strong and collapse-proof agricultural cultivation greenhouse includes multiple groups of arc-shaped frames 1 arranged in parallel. The bottom of the frame 1 is buried 0.4 meters below the foundation through bricks or concrete to ensure the stability of the frame 1. The outer side of the frame 1 is provided with an outer arch rod 101, and the inner side is provided with an inner arch rod 102. A continuous S-shaped reinforcement tube 103 is welded between the outer arch rod 101 and the inner arch rod 102. The outer arch rod 101 and the inner arch rod 102 are connected as a whole through the S-shaped reinforcement tube 103. The structural strength is much greater than the support of a single rod. Multiple horizontal pull rods 2 are fixedly connected between the multiple outer arch rods 101. The multiple frames 1 are connected through the pull rods 2 to strengthen the overall connectivity and stability of the greenhouse. Auxiliary support devices 3 are respectively installed on the pull rods 2 between adjacent frames 1; the auxiliary support devices 3 It includes a center sleeve 301, a rib support rod 302, a base 303, and a top seat 304. The center sleeve 301 is sleeved on the pull rod 2. The rib support rod 302 is symmetrically located on the front and rear sides of the center sleeve 301, so that the center sleeve 301 is located in the middle of the pull rod 2, which is also in the middle between adjacent skeletons 1, so that the load-bearing effect of the rib support rod 302 is more significant. One end of the rib support rod 302 is hingedly installed with the inner arch rod 102 through the base 303, and the other end is hingedly installed with the center sleeve 301 through the top seat 304. The rib support rod 302, the pull rod 2 and the skeleton 1 form a triangular structure, so that the load-bearing structure is the most stable. The rib support rod 302 disperses the force it bears to the inner arch rod 102, thereby strengthening the support of the rib support rod 302 and preventing it from being bent and deformed by accumulated snow. The front end skeleton 1 is equipped with a heating device 4.

[0023] Furthermore, the center sleeve 301 includes an upper shell 3011, a lower shell 3012, a hinge 3013, a pressure plate 3014, and a bolt 3015. The upper shell 3011 and the lower shell 3012 are both semicircular cylindrical, and one side is connected by a hinge 3013 and wrapped around the pull rod 2, and the other side is integrally formed with a pressure plate 3014. The two pressure plates 3014 are fixed closed by bolts 3015, which facilitates the disassembly and assembly of the center sleeve 301 and facilitates separate replacement after damage, saving maintenance costs.

[0024] The pull rod 2 is hollow and cylindrical, with one end open and the other end sealed, and the outer wall is provided with a plurality of blowing ports 201 to ensure that the hot air can be evenly dispersed outside the pull rod 2. The warm air device 4 comprises a heater 401, a blower 402, and an evacuation pipe 403. The heater 401 is heated by an electric heating wire and is connected to the air inlet end of the blower 402 through a hose. The air outlet end of the blower 402 is connected to the evacuation pipe 403 through a hose. The evacuation pipe 403 is connected to the open ends of the plurality of pull rods 2. By blowing hot air into the pull rods 2, and because the blowing port 201 is closest to the plastic film of the greenhouse, the accumulated snow outside the plastic film can be heated and warmed, and the temperature is controlled within the tolerance range of the cultivated plants and the plastic film of the greenhouse, thereby fundamentally solving the problem of snow accumulation, reducing the load-bearing burden of the greenhouse, and avoiding economic losses.

[0025] The working principle of the utility model is: since the greenhouse is supported by the frame 1, a large amount of snow will accumulate in the concave positions between the frames, causing the pull rod 2 to bear a large gravity. The gravity exerted by the snow on the pull rod 2 is dispersed to the inner arch rod 102 through the rib support rod 302, and supported together by the frame 1, thereby reducing the burden on the pull rod.

[0026] If there is a lot of snow, start the heater 401 and the blower 402, divert the hot air from the evacuation pipe 403 into the hollow pull rod 2, and blow hot air to the greenhouse plastic film through the blowing port 201 to accelerate the melting of the snow and reduce the load-bearing burden of the greenhouse.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
