Agricultural planting greenhouse capable of automatically removing snow

Abstract

The invention discloses an agricultural planting greenhouse capable of automatically removing snow. The agricultural planting greenhouse comprises a greenhouse body; the greenhouse body is composed ofsupporting plates fixedly connected to the ground and a greenhouse framework; a transverse fixed beam is fixedly connected to the top of the greenhouse framework; the greenhouse framework and the fixed beam are jointly connected with a semi-arc-shaped plastic film; a sliding cavity is formed in the fixed beam; the cavity walls of two ends of the sliding cavity are rotationally connected with a reciprocating lead screw; and a lead screw sliding block is connected with the interior of the sliding cavity in a sliding mode. The device has the advantages that in the sliding process of the lead screw sliding block, a conducting rod can generate induction current through magnetic induction line cutting when passing through the magnetic block, so that a conducting spring shrinks; and through interval distribution of a plurality of magnetic plates and interruption of the current flowing through the conducting spring, the conducting spring is intermittently compressed, bounced off and recompressed a vibrating plate moves back and forth to beat and vibrate the plastic film, residual accumulated snow on the plastic film is removed, and the snow removing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural greenhouses, in particular to an agricultural planting greenhouse for automatic snow removal. Background technique [0002] Agricultural greenhouses are special equipment for planting crops, especially vegetables. With the production of high molecular polymers-polyvinyl chloride and polyethylene, plastic films are widely used in agriculture. With the development of production, agricultural greenhouses are used more and more widely, thus Different types of agricultural technology greenhouses have appeared in the market. Agricultural greenhouses can grow vegetables in greenhouses and realize off-season cultivation of vegetables, so that people can eat delicious vegetables all year round. [0003] In Northeast my country, snowfall occurs frequently in winter, and plastic film is mostly used in agricultural greenhouses. If the greenhouses need to be covered with snow, it will not only affect the ...

AI Technical Summary

Problems solved by technology

[0003] In Northeast my country, snowfall occurs frequently in winter, and plastic film is mostly used in agricultural greenhouses. If the greenhouses need to be covered with snow, it will not only affect the irradiation of light, but also make the crops in the greenhouses unable to receive good sunlight, which will affect the photosynthesis of crops. The growth rate of crops is slowed down, and the snow weight exceeds the bearing capacity of the plastic film, which collapses and causes damage to crops. Therefore, we propose an agricultural planting greenhouse with automatic snow removal
