Agricultural planting greenhouse with automatic cooling function

Abstract

The invention discloses an agricultural planting greenhouse with an automatic cooling function, which comprises a greenhouse body composed of support plates fixedly connected to a ground and a greenhouse framework; the two vertical plates are symmetrically and fixedly connected to the ground, a hollow plate is fixedly connected to the upper ends of the vertical plates, air guide plates are uniformly distributed on and communicated with opposite side walls of the hollow plate, and one end, far away from the side wall of the hollow plate, of each air guide plate is fixedly connected with a sun-shading plate that is of hollow structure. According to the invention, when external sunlight irradiation temperature rises in the noon, a thermal expansion liquid expands rapidly, so that air is introduced into the sun-shading plates that stretch to shield greenhouse protective film, the direct irradiation of sunlight to the greenhouse is reduced, the rise range of the temperature in the greenhouse is narrowed; when the external sunlight irradiation temperature falls, the thermal expansion liquid contracts so that the air in the sun-shading plates contracts less, manually laying and removing sunshade net is prevented, and the workload of people is reduced.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to an agricultural planting greenhouse with an automatic cooling function. Background technique [0002] The greenhouse is a device used to cultivate crops in order to quickly obtain high-quality crops and increase the yield of crops. [0003] When cultivating crops in agricultural greenhouses, it is necessary to keep the temperature and sunlight irradiance in the greenhouses at the production level of the crops. However, at noon in summer, strong sunlight will cause a large increase in the evaporation of water in the greenhouses, making the seedlings wilt and dry. A series of hazards directly affect the output of crops. At present, when cooling the greenhouse at noon in summer, most of them use sunshade nets to shade the greenhouses to achieve the sunshade effect.

[0003] When cultivating crops in agricultural greenhouses, it is necessary to keep the temperature and sunlight irradiance in the greenhouses at the production level of the crops. However, at noon in summer, strong sunlight will cause a large increase in the evaporation of water in the greenhouses, making the seedlings wilt and dry. A series of hazards directly affect the output of crops. At present, when cooling the greenhouse at noon in summer, most of them use sunshade nets to shade the greenhouses to achieve the sunshade effect. However, the laying of sunshade nets is currently done by people at noon. , it needs to be disassembled in the afternoon, which increases people’s work intensity, and working in an environment with too high temperature can easily cause people to suffer from heat stroke. In addition, when laying the sunshade net on the greenhouse, the sunshade net is directly connected with the greenhouse protective film contact, which is not conducive to the dissipation of heat inside the greenhouse
