Description

Technical Field

[0001] The utility model belongs to the technical field of agriculture, and more specifically, relates to a multi-span film greenhouse. Background Art

[0002] Greenhouse, also known as hothouse, is a facility for cultivating plants that can transmit light and keep warm. It can provide a greenhouse growth period and increase yields in seasons that are not suitable for plant growth. It is mostly used for cultivating or raising seedlings of warm-loving vegetables, flowers, trees and other plants in low temperature seasons. There are many types of greenhouses, which can be divided into many categories according to different roof truss materials, lighting materials, appearance and heating conditions. The special plastic film used in the construction of facility agricultural production has excellent light transmittance, heat preservation, tensile strength and aging resistance. Connecting and placing the film greenhouses can significantly improve the stability and spatial depth.

[0003] Based on the above, the inventors found that the following problems exist: most of the existing greenhouse structures are one-piece structures. When the temperature in the greenhouse rises, the film needs to be lifted up manually from the side. Such repeated operations not only increase the workload, but are also not conducive to heat preservation. In addition, traditional greenhouses all adopt a single-roof design. When large areas of snow accumulate, the pressure on the roof will be too great, which can easily cause collapse.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a multi-span film greenhouse is provided in order to achieve a purpose with greater practical value. Utility Model Content

[0005] The purpose and effect of the multi-span greenhouse of this utility model are achieved by the following specific technical means:

[0006] The top of the vertical rod is connected to the bottom end face of the vertical rod, and the top of the vertical rod is connected to the bottom end face of the vertical rod by the hinged structure.

[0007] Furthermore, both ends of the air tower arch rod are respectively connected to side support rods, and the other end of the side support rod is connected to the connection between the air tower vertical rod and the arch rod.

[0008] Furthermore, the side support rods and the air tower arch rods form the air tower structure top, and the columns and the arch rods form the greenhouse roof.

[0009] Furthermore, scissor braces are welded between the upright columns on one side, and the scissor braces are distributed in a diamond shape.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The design of scissor braces can increase the stability between the columns, so that the stability between the multi-span greenhouses can be improved to avoid collapse.

[0012] Through the design of the air tower structure and the greenhouse roof, this multi-span greenhouse has a double-top structure design, which can alleviate the pressure of snow accumulation on the roof and reduce the possibility of the greenhouse roof collapsing.

[0013] Through the design of the longitudinal tie rod, the stability between the air tower pole and the column can be increased, and the horizontal pulling force can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

Through the design of the auxiliary rods 8, the stability of the overall structure of the greenhouse roof 7 can be increased.

[0026] Among them, several longitudinal tie rods 3 are welded at equal intervals on the surface of the arch rod 2, and some of the connection parts of the longitudinal tie rods 3 and the air tower uprights 11 are in a welded state. Through the design of the longitudinal tie rods 3, the stability between the air tower uprights 11 and the columns 1 can be increased, and the pulling force in the horizontal direction can be improved.

The top of the middle support rod 10 is connected to the center of the bottom end surface of the air tower arch rod 4 and is used to support the air tower arch rod 4. Through the design of the middle support rod 10, the overall supporting strength of the air tower arch rod 4 can be increased, so that the top 6 of the air tower structure is designed in a bow shape, thereby improving its overall anti-backlog ability.

[0028] Wherein, both ends of the air tower arch rod 4 are connected to side support rods 9 respectively, and the other end of the side support rod 9 is connected to the connection between the air tower vertical rod 11 and the arch rod 2.

The design of the auxiliary rod 8 can increase the stability of the overall structure of the greenhouse roof 7. Then, the design of the longitudinal pull rod 3 can increase the stability between the air tower upright pole 11 and the column 1, and the horizontal pulling force can be improved. Then, the design of the longitudinal pull rod 3 can increase the stability between the air tower upright pole 11 and the column 1, and the horizontal pulling force can be improved. Finally, the design of the air tower structure top 6 and the greenhouse roof 7 makes this multi-span film greenhouse have a double-top structure design, which can alleviate the pressure of snow accumulation on the roof and reduce the collapse of the greenhouse roof. The design of the scissors support 13 can increase the stability between the columns 1, so that the stability between the multi-span film greenhouses can be improved to avoid collapse. The double-layer roof design can help keep warm and prevent snow from accumulating directly on the top, causing collapse due to excessive roof pressure. At the same time, vents are opened on both sides to generate opposing gases in the shed, which is conducive to the growth of crops in the shed.
