Hemispheric combined type greenhouse net rack

Abstract

The invention discloses a hemispheric combined type greenhouse net rack. Horizontal circular pull pipes are arranged on a greenhouse net rack body from the top to the lower end, wherein the horizontal circular pull pipes are arranged at intervals, and the centers of the horizontal circular pull pipes are located on the same plumb line. Arch-shaped bracing pipes connected in a crossed mode are arranged on the greenhouse net rack body from the top to the lower end. The horizontal circular pull pipes and the arch-shaped bracing pipes are evenly connected into a plurality of triangular frames and then form the greenhouse net rack body through screws. Each layer of bracing pipes are located above the corresponding pull pipes. The upper pull pipes, the lower pull pipes and the middle pull pipes are evenly connected with the upper bracing pipes, the lower bracing pipes and the middle bracing pipes through screws to form the triangular frames, and every two adjacent triangular frames share one edge and two connection points. Based on the principle that triangles are the most stable, the stability of the hemispheric combined type greenhouse net rack is greatly enhanced, the wind chill resistance is enhanced, and each face can receive light, so the light is sufficient; the hemispheric combined type greenhouse net rack is convenient to disassemble and assemble after erection and can be reused.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a hemispherical combined greenhouse grid. Background technique [0002] At present, the grid structures of greenhouses are mostly 1 / 4 arc-shaped or arched structures, which are composed of parallel 1 / 4 arc bars or arched bars. Insufficient, the cold resistance of the greenhouse is poor, and the light area is small, which affects the yield and quality of the crops in the shed; at the same time, after construction, the greenhouse grid cannot be disassembled or disassembled, and the reuse rate is low. Contents of the invention [0003] The object of the present invention is to provide a detachable hemispherical combined greenhouse network frame with reasonable structure, good stability, strong wind and cold resistance, sufficient lighting and assembly, so as to solve the deficiencies in the prior art. [0004] The technical scheme adopted by the present inventio...
