Snow accumulation prevention device for ecological agriculture planting greenhouse

Abstract

The invention discloses a snow accumulation prevention device for an ecological agriculture planting greenhouse. The device comprises a vertical supporting rod, the upper portion of a transverse supporting rod is fixedly connected with a light windpipe, the light windpipe is fixedly communicated with an elastic air bag, the elastic air bag comprises an inner cylinder and an air bag cover, the surface of the inner cylinder is provided with air vents, two ends of the inner cylinder are respectively and fixedly connected with connectors, two ends of the air bag cover are respectively in sealing sleeved connection to the connectors, one end of the light windpipe is communicated with an inflator pump through a gas filled tube, the other end of the light windpipe is communicated with a sucking pump through a suction pipe, the gas filled tube is provided with a first solenoid valve, and the suction pipe is provided with a second solenoid valve. The snow accumulation prevention device for theecological agriculture planting greenhouse has the advantages that the elastic air bag can be internally inflated and deflated in heavy snow weather, the purpose of flapping and jacking up plastic film of a plastic greenhouse is achieved, the greenhouse is prevented from being collapsed due to the fact that snow accumulation on the upper portion of the greenhouse is excessive, through the cycle work of the sucking pump and inflator pump, manual interference is not needed, and a lot of manpower is reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a snow prevention device for ecological agricultural planting greenhouses. Background technique [0002] Agricultural greenhouses were originally special equipment for vegetable production. With the development of production, the application of greenhouses has become more and more extensive. It has been used for potted flower and cut flower cultivation; fruit tree production is used to cultivate grapes, strawberries, watermelons, melons, peaches and citrus, etc.; forestry production is used for tree seedling cultivation, ornamental tree cultivation, etc.; , Raising cattle, raising pigs, raising fish and fry, etc. The composition of the greenhouse is to use bamboo and wood poles, cement poles, light steel pipes or pipes as the skeleton, make upright columns, tie rods, arch rods and pressure rods, and cover them with plastic film to form an arched materia...
