Efficient greenhouse plastic film guide lifting system

Abstract

The invention discloses an efficient greenhouse plastic film guide lifting system. The efficient greenhouse plastic film guide lifting system comprises an arch greenhouse frame, a plastic film is attached to the arch greenhouse frame, film clamping devices are arranged at the two sides of the arch walls of the arch greenhouse frame and make contact with the ground surface, guide rails and lifting mechanisms are arranged on arch frames at the two ends of the arch greenhouse frame respectively, and the guide rails are of axial symmetry about the connecting line of gravities of the two lifting mechanisms. The system is capable of conveniently and efficiently opening or laying down a greenhouse plastic film in a labor-saving mode, and the problem that when a traditional arch greenhouse needs to be ventilated, the plastic film is manually lifted up little by little, which wastes labor and is low in working efficiency is solved.

Description

technical field [0001] The invention relates to the field of agricultural auxiliary machinery, in particular to a high-efficiency greenhouse plastic film guiding and lifting system. Background technique [0002] The vegetable greenhouse is a frame-covered structure with excellent thermal insulation performance. It appears that people can eat off-season vegetables. Generally, the vegetable greenhouse uses a bamboo structure or a steel structure frame, covered with one or more layers of thermal insulation plastic film, thus forming a greenhouse space. The outer film can well prevent the loss of carbon dioxide produced by the growth of vegetables inside, so that the shed has a good heat preservation effect. [0003] Vegetable greenhouses sometimes also lift the greenhouse film to ventilate the vegetable greenhouse so that the vegetables can grow better. Vegetable greenhouses in the prior art are often built with arched poles. If only the plastic film on the two ends of the gr...

Problems solved by technology

[0004] The technical problem to be solved by this invention is that when traditional arched greenhouses need to be ventilated, the plastic film can only be lifted up manually. This method is not only laborious, but also has low work efficiency. The plastic film guide lifting system realizes the purpose of a system that can lift or put down the plastic film of the greenhouse conveniently, labor-savingly and efficiently at one time
