Anti-pneumatic film type fruit tree rainproof facility

Abstract

The invention discloses an anti-pneumatic film type fruit tree rainproof facility. The facility consists of wire pressing ground anchors, wire supporting ground anchors, boundary stay bars, longitudinal bracing wires, film pressing wires, a roll-up unit scroll, an electric roll-up unit, an arch bar or film supporting wire, a rainproof ventilation plastic film, a top ridge, a film fixing clamping groove, boundary struts, middle spines, a rainproof covering plastic film, and a plastic clamp; and the facility has a bar and cable combined structural system combining rigidity and flexibility. The anti-pneumatic film type fruit tree rainproof facility can realize the automatic exchange of air inside and outside the facility, the air inside the facility automatically jacks up the rainproof ventilation plastic film to exhaust when the internal pressure of the air is greater than the external pressure, and the rainproof ventilation plastic film droops due to the action of gravity to recover the original shape when the internal pressure and the external pressure are balanced; years of experiments show that the facility can safely stand the test of high wind and heavy rain in northern autumn; and the facility has the characteristics of rainproofness, high ventilation efficiency, no building pollution, simple construction, sturdiness and durability, convenience in use and the like.

Description

technical field [0001] The invention belongs to the field of modern agricultural facilities, and relates to a rainproof facility for fruit trees, in particular to a wind-resistant dynamic membrane type rainproof facility for fruit trees. Background technique [0002] Jujube trees are native to my country and are mainly distributed in the Yellow River Basin. Jujube has already become the main edible fruit for people to prolong their lives, and is very popular with consumers, and growers can obtain high economic benefits. However, in the yellowing period before fruit ripening, jujube trees are most afraid of being exposed to rain. Once it rains, jujubes will quickly rot and deteriorate, and the worst ones will never be harvested. And this period happens to be the rainy season, and usually the fruit has to be harvested in advance when it is immature, or it is helpless to watch the ripe dates rot. [0003] Though someone uses the greenhouse method to prevent rain, its technica...

AI Technical Summary

Problems solved by technology

Although this greenhouse-type rainproof technology can prevent rain during the production process, there are a series of problems such as poor wind resistance, poor ventilation, poor lighting of fruit trees, high temperature steam transpiration after rain, and fruit rot and deterioration.
