Adjustable grain drying device

Abstract

The invention discloses an adjustable grain drying device, and relates to the technical field of grain drying. The adjustable grain drying device comprises an air supply box and a first drying box, wherein a plurality of second drying boxes are arranged side by side between the air supply box and the first drying box; ventilation cavities are formed in the lower part of the first drying box and the lower parts of the second drying boxes respectively; the side wall of the air supply box and the side walls of the ventilation cavities are connected with air supply valves; adjacent two air supplyvalves are connected through air delivery pipes; the upper part of the air supply box and the upper parts of the second drying boxes are rotationally connected with transmission worm wheels; a plurality of rotary worms are meshed on the transmission worm wheels; first connecting rods are fixed to the rotary worms in the radial direction; one end of each first connecting rod is rotationally connected with a second connecting rod; and one end of each second connecting rod is rotationally connected to the first drying box or the second drying boxes. The adjustable grain drying device is not onlysimple and reasonable in structural design, and convenient to use, but also effectively improves the grain drying efficiency, and has relatively high market application value.

Description

technical field [0001] The invention belongs to the technical field of grain drying, in particular to an adjustable grain drying device. Background technique [0002] my country is a large agricultural country with an annual grain output of hundreds of millions of tons. Grain storage has always been the top priority in the agricultural field. Before storage, grain needs to be dried to reduce internal moisture and increase the storage period. At present, in the prior art, the grain is usually laid on the road surface for drying. This method is more popular now, but this method will occupy the road surface, which is not convenient for vehicles or passers-by to walk, and the amount of grain drying is limited. Therefore, it is urgent to study an adjustable grain drying device, so as to solve the above problems. Contents of the invention [0003] The present invention is to provide an adjustable grain drying device, and its purpose is only to solve the problems raised in the a...
