Agricultural greenhouse frame and its connecting device

Abstract

The invention provides an agricultural greenhouse frame and a connecting device thereof. Installation efficiency is high, resource waste is small, and the height of an arc-shaped ceiling can be adjusted according to requirements. The agricultural greenhouse frame comprises arch tubes and vertical columns. The vertical columns are arranged transversely and longitudinally at intervals to form a greenhouse frame body, transverse and longitudinal steel rope and arch tube connecting devices capable of being used for fixing longitudinal steel strands, transverse steel strands and the arch tubes are arranged above the vertical columns at the front portion, the rear portion, the left side and the right side of the greenhouse frame body in a vertically-lifting mode, the two ends of the transverse steel strands and the longitudinal steel strands are fixed above the two transverse sides and the two longitudinal sides of the greenhouse frame body through the transverse and longitudinal steel rope and arch tube connecting devices, arch tube connecting devices are correspondingly arranged above the adjacent longitudinal steel strands, the arch tubes are fixed between the arch tube connecting devices, supporting vertical columns are arranged at the portions, located below the middle portions of the arch tubes, of the greenhouse frame body, lifting rods are arranged above the supporting vertical columns through lifting connecting devices in a vertically-moving mode, and the upper portions of the lifting rods are connected with longitudinal arch tube supporting pipes through top pipe connecting devices.

Description

technical field [0001] The invention relates to the field of agricultural production tools, in particular to an agricultural greenhouse frame and a connecting device thereof. Background technique [0002] Agricultural greenhouses have been widely used in agricultural production activities such as vegetable planting, flower cultivation and seedling breeding all over the world. The basic structure is composed of steel frame main body and thermal insulation plastic film. The external awning is equipped with supporting facilities such as rainproof, windproof, cold-proof and modern agricultural technology facilities, so as to realize vegetable planting, flower cultivation and seedling breeding in any season, thus enabling the transformation from traditional agriculture to modern scientific and technological agriculture. Successfully achieved. [0003] The traditional greenhouse skeleton is generally composed of several arch tubes and columns. The arch tubes are bent by metal tub...

AI Technical Summary

Problems solved by technology

[0003] The traditional greenhouse skeleton is generally composed of several arch tubes and columns. The arch tubes are bent by metal tubes to form a certain span of curved arc-shaped tubes as the roof. Arrange at intervals to form a greenhouse frame body, and then twist two adjacent arch tubes together through iron wires, and then fix each arch tube on the column through steel strands, and finally use beams and longitudinal beams between the horizontal and vertical sides of the greenhouse frame To build the connection, the adjacent arch tubes of the greenhouse frame are manually tightened with iron wires, and the vertical and horizontal steel strands are manually fixed and connected between the arch tubes and the columns. Low efficiency, poor firmness, lack of strength in load bearing, wind resistance and compression resistance, unsightly and easy to collapse when used

In addition, the horizontal and vertical connections of the greenhouse frame are made of pipes such as beams and longitudinal beams. The material waste is large and the cost is high during construction. The beams and longitudinal beams are generally fixed on the columns or arch pipes by welding, and ordinary people do not know how to weld. , requires professional welders to complete, which further increases labor costs; in addition, with this installation method, once installed, it is difficult to disassemble, which is not conducive to changing the position and structure of the arc-shaped ceiling. Once the height of the arc-shaped ceiling is fixed, it cannot be adjusted according to needs. It is not conducive to adapting to different crops in different seasons and different soils
