A grain dryer with screening function

Abstract

The invention relates to an efficient grain drying machine with a sieving function. The efficient grain drying machine with the sieving function comprises a main body, a heater, a support and a conveyor belt, and further comprises a feeding mechanism and a sieving mechanism, wherein the feeding mechanism comprises a storage through, a discharge through, a sieve plate, a driving component, two supporting plates and two supporting components; the sieving mechanism comprises a water pump, a fan, two first pipelines, two supporting rods and two heat exchange components; the supporting component comprises a sliding rod, a movable casing pipe and two elastic cords; each heat exchange component comprises an outer frame, a second pipeline and at least two heat exchange pieces; in the efficient grain drying machine with the sieving function, the discharge through and the sieve plate are driven to do reciprocating motions through the feeding mechanism, grains are uniformly sprayed and paved on the conveyor belt through the sieve plate, the heated uniformity of the grains is improved, the drying efficiency of the grains is improved, under the effect of the sieving mechanism, inferior grains in the grains can be removed through a fan, and the grain quality is improved.

Description

technical field [0001] The invention relates to the field of agricultural equipment, in particular to a grain dryer with screening function. Background technique [0002] Grain dryer is a kind of dryer assembly, which is a general term for various equipment of grain dryer, and can also be called grain dryer, such as corn dryer, rice dryer, rice dryer, Wine dross dryer, etc., we can all call it grain dryer. According to the relative movement direction of grain and airflow, dryers can be divided into cross flow, mixed flow, forward flow, countercurrent and forward and reverse flow, mixed and reverse flow, forward and mixed flow, etc. type. [0003] As a kind of agricultural equipment, the grain dryer plays an important role in the preservation of grain. During the working process of the grain dryer in the prior art, the grain is easy to pile up together, resulting in uneven heating of the grain, and the The drying effect of the grain dryer is reduced. Not only that, but ther...

[0003] As a kind of agricultural equipment, the grain dryer plays an important role in the preservation of grain. During the working process of the grain dryer in the prior art, the grain is easy to pile up together, resulting in uneven heating of the grain, and the The drying effect of the grain dryer is reduced. Not only that, but today's grains are mixed with more inferior or shriveled grains and impurities. If the grains are not screened, the quality of the grains will be reduced
