Grain dryer for modern agriculture

Abstract

The invention discloses a grain dryer for modern agriculture. The grain dryer for modern agriculture structurally comprises a grain storage layer, a lifting assembly, a drying layer and a grain stirring layer, the bottom of the grain storage layer is attached to the top of the drying layer and communicates with the top of the grain stirring layer, the lifting assembly conveys dried grains enteringa grain conveying opening along the upper portion of a conveying pipe through a hanging hopper, an air heater conveys hot air into a pipeline through an air conveying pipe, a fan presses the hot airinto branch thin pipes to enable the hot air to enter the conveying pipe layer by layer, the temperature in the conveying pipe is kept, capillary holes in the inner side of the hanging hopper facilitate hot air entering and temperature keeping, if the temperature or pressure is too high, a pressure reduction cover rotates along a clamping shaft according to the pressure value to gradually open a heat dissipation opening, the temperature and the pressure are reduced to safety values, so that waist bursting and cracking caused by overheating of grains are avoided, air is sucked into the hot airblower after being filtered by a main filter screen on an air suction port and then is secondarily filtered by a secondary filter screen in an air outlet, so that impurities are prevented from entering the grains along with airflow, and the impurities are prevented from affecting normal operation of the dryer.

Description

technical field [0001] The invention belongs to the field of modern agriculture, and more specifically relates to a grain dryer for modern agriculture. Background technique [0002] Modern agricultural grain dryers are usually used to dry rice and other seeds for storage. They are mainly divided into warehouse-type drying and tower-type drying. Among them, tower-type drying equipment is used more, which is characterized by hot air and dividing grain into watersheds. Circular drying or continuous drying requires different drying wind directions and temperatures according to the differences in grain moisture content and skin structure, and the grain is transported from the drying layer through lifting components for continuous drying. Based on the above inventors' discovery, The existing ones mainly have the following deficiencies, such as: [0003] When dealing with corn seeds with high water content, the tower-type grain dryer is prone to uneven temperature between the uppe...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above-mentioned technology when processing seeds with high water content such as corn, the tower type grain dryer is prone to bursting during the circulation drying due to the uneven temperature of the upper and lower parts when the lifting components are transported during the horizontal hot air treatment process.
