An automatic snow removal device for agricultural planting greenhouses

Abstract

The invention relates to the technical field of agricultural equipment, and discloses an automatic snow removal device for agricultural planting greenhouses, which includes a longitudinal support, and the sliding seat includes: a chute, an air inlet hole, an air delivery hole and an air outlet hole, and the upper end of the sliding seat is connected to There is a moving strut, the lower end of the moving strut is equipped with a metal ball, the inside of the sliding seat is connected with an air bag, the inner side of the insulating plate is connected with a variable resistor, the outside of the rotating shaft is connected with a swing rod, and the inside of the swing rod is connected with a movable pole. The snow accumulation drives the moving support rod to move downward through the arc-shaped support frame, the moving support rod drives the swing rod to swing through the rotating shaft, the swing rod drives the movable rod to move down, and the moving support rod drives the metal ball at the lower end to contact the variable resistor, blowing air The device blows air to the film intermittently, and the snow slides down. This structure achieves automatic snow cleaning, and the automatic adjustment of the cleaning output can be achieved with the different positions of the metal ball on the variable resistor.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to an automatic snow removal device for agricultural planting greenhouses. Background technique [0002] Agriculture is an industry that uses the growth and development laws of animals and plants to obtain products through artificial cultivation. Agriculture belongs to the primary industry, and the science that studies agriculture is agronomy. The objects of labor in agriculture are living animals and plants, and the products obtained are the animals and plants themselves. Agriculture is the basic industry that provides support for the construction and development of the national economy. The agricultural greenhouse is widely used in agriculture with the production of high molecular polymers - polyvinyl chloride and polyethylene. In the early 1950s, Japan, European and American countries successfully applied greenhouse films to cover hotbeds, and then covered small...
