Abstract

The invention discloses a forward and reverse rotation drum type grain drying device which comprises a base, a drying cylinder, a motor and an air heater. According to the forward and reverse rotation drum type grain drying device, a transmission mechanism is utilized to realize forward and reverse rotation of the drying cylinder; during the process of forward and reverse rotation, the drying cylinder can swing grain the drying cylinder to avoid grain accumulation so as to uniformly heat the grain; an air heating pipe is arranged in the center of the drying cylinder to dissipate heat from the center to the periphery so as to uniformly distribute heat of the drying cylinder, and a material turnover rod can turn over grain in the drying cylinder to further ensure that the grain is uniformly heated; in addition, the drying cylinder can do reciprocating motion left and right, so that the material turnover rod can turn over the grain in an all-around manner and the material turnover range is larger; a lantern ring with embedded balls is arranged to ensure rotating stability of the drying cylinder and does not affect left-right movement of the drying cylinder; and filtration holes are formed in the cylinder wall of the drying cylinder to effectively filter dust and impurities in the grain.

Description

technical field [0001] The invention relates to a drying device, in particular to a forward and reverse drum type grain drying device. Background technique [0002] my country is the most populous country in the world, and the food problem has always been the primary problem. The moisture content of grain is high when it is just harvested, so it cannot be stored and transported immediately after harvest. Usually, it must be dried in a system to reduce the moisture content of the grain to the safe storage moisture standard before it can be put into storage. [0003] Some of the existing grain drying devices are of the drum type. During the drying process of these devices, the drum simply rotates in one direction, which causes the grain to accumulate in a certain area of ​​the drum under the action of centrifugal force, resulting in The uneven heating of the grain affects the drying effect. Contents of the invention [0004] The object of the present invention is to provid...
