Solar grain air-drying greenhouse

Abstract

The invention discloses a solar grain air-drying greenhouse which comprises a greenhouse, a grain air-drying bin, a heating system and an air generating system, wherein the grain air-drying bin is arranged in the greenhouse; the air generating system consists of two rows of air generating devices which are respectively arranged on the front and rear sides of the grain air-drying bin; each row of air generating devices consists of a fan, a transmission shaft, a bracket, an upper rocking mechanism and a lower rocking mechanism; the fan is fixed on the transmission shaft; the transmission shaft is supported on the bracket through a bearing seat; the upper and lower rocking mechanisms are connected with the transmission shaft; the heating system consists of a solar heat collecting tube and a heat radiating fin; the solar heat collecting tube is mounted outside the greenhouse; and the heat radiating fin is mounted in the greenhouse and connected with an outlet of the solar heat collecting tube through a connecting tube. The solar grain air-drying greenhouse disclosed by the invention is green and environment-friendly, saves energy, occupies small area of land, has high production efficiency, is free from influence of seasons, regions and weather, and can realize quick dehydration and air-drying of grain crops by means of solar heat sources and manually-generated air.

Description

technical field [0001] The invention relates to an air-drying device for grain crops, in particular to a device for dehydrating and air-drying grain crops by using solar energy and wind energy, in particular to a solar-energy grain air-drying greenhouse. Background technique [0002] Drying corn and other food crops after harvest is a difficult problem for farmers. Using the site to dry grain takes up a large area and requires manual turning of the grain. The production efficiency is low, the ground is not ventilated, and the food crops are in contact with the ground, which is easy to get damp and stick to the ground If the drying equipment is used, it needs to consume a lot of coal, which is a large investment, high cost, and seriously pollutes the environment. High-temperature drying will also destroy the nutrients inside the food crops. For this reason, I have successively developed a grain air-drying warehouse and a suction-type energy-saving and environment-friendly gra...

Problems solved by technology

[0003] However, these two kinds of grain air-drying warehouses are exposed to the natural environment and are greatly affected by seasons, regions, and climates. In winter or rainy weather or areas with high coastal humidity, the drying effect is poor, or even unusable.
