Grain drying device

Abstract

The invention relates to a grain drying device. The grain drying device comprises a cyclone cap, a cyclone cabin, a cabin cap, a drying cabin, supporting legs and an air gathering opening; the drying cabin is supported by the supporting legs, the cabin cap is arranged above the drying cabin, the cyclone cabin is arranged above the cabin cap, the cyclone cap is installed above the drying cabin, the cyclone cabin is arranged above the cabin cap, and the cyclone cap is installed above the cyclone cabin; the air gathering opening is formed at the lower part of the drying cabin, the drying cabin is used for storing grains, air enters the drying cabin by virtue of the air gathering opening and is discharged from the cyclone cap by virtue of the cyclone cabin, and a chimney effect is formed so that the air in the drying cabin is exhausted upwards, and a purpose of drying the grains in the cabin can be realized. A plurality of air holes are formed in the drying cabin; a fan is arranged in the cyclone cabin, the fan is connected with the cyclone cap at the top of the cyclone cabin by virtue of a fan shaft, and the fan is driven by the cyclone cap to rotate so as to accelerate the air in the drying cabin to flow upwards; the air gathering opening is in a flared shape, so that the air gathering volume is increased, the flow rate of the air entering the drying cabin is increased, and the drying efficiency is improved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a grain drying device. Background technique [0002] In order for the grain to be stored better, the harvested grain needs to be dried in time. There are two traditional drying methods: one method is to use sunlight for natural drying. Although this method saves energy, it is difficult to grasp the weather conditions. Once it encounters sudden rainy weather, the dried grains will be wet. And then moldy, causing huge losses; Another method is to adopt special drying machinery to dry, but traditional drying machinery needs to consume a lot of energy. [0003] In summer, the air is dry and the sun is sufficient. If the grains are piled up or stored in a concentrated manner, the natural wind can be heated by solar energy to dry the grains. This will not only save energy, but also do not require guards. Unfortunately, such devices do not exist at present. Contents ...
