Agricultural greenhouse with high stability

Abstract

The invention discloses an agricultural greenhouse with high stability, and relates to the technical field of agricultural greenhouses. The agricultural greenhouse comprises the ground, a greenhouse ceiling is fixedly connected to a lifting threaded block, a water collection device is arranged in the middle of the greenhouse ceiling, a limiting slide rail is fixedly connected to one side of a right supporting frame, and a pneumatic rotating rod penetrates through and is rotatably connected to the interior of a first bearing; pneumatic blades are fixedly connected to the two sides, close to thetop, of the pneumatic rotating rod, a transmission shaft penetrates through the interior and is rotatably connected to the interior of a second bearing, and a first transmission wheel and a second transmission wheel are fixedly connected to the left and right ends of the transmission shaft respectively. According to the agricultural greenhouse with high stability, the purposes that in gale weather, the greenhouse ceiling is automatically lowered to be prevented from being blown over, thus the economic loss and personnel injuries are lowered, vegetables, melons and fruits are not influenced bythe external environment, the greenhouse is prevented from collapsing under pressure of accumulation water, the stability of the agricultural greenhouse is improved, rainwater is collected to irrigate the vegetables, and the water resource is saved are achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural greenhouses, in particular to an agricultural greenhouse with strong stability. Background technique [0002] With the emergence of high molecular polymers - polyvinyl chloride and polyethylene, plastic films are widely used in agriculture. In the early 1950s, Japan, European and American countries successfully applied greenhouse films to cover hotbeds, and then covered small sheds and greenhouses with good results. my country introduced polyvinyl chloride agricultural film in the autumn of 1955. It was first used to cover vegetables in small sheds in Beijing, and achieved the effect of early maturity and increased production. The greenhouse was originally a special equipment for vegetable production. With the development of production, the application of greenhouses has become more and more extensive. At present, greenhouses have been used for potted flower and cut flower cultivation; frui...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an agricultural greenhouse with strong stability, which solves the problem that the stability of the agricultural greenhouse is relatively poor, and the roof is prone to breakage or the shed canopy can Being blown over, causing economic losses, and greatly affecting the growth of vegetables and fruits
