A high-efficiency grain dryer

Abstract

The invention discloses an efficient grain drying machine. The efficient grain drying machine comprises a drying box body, a drying mechanism, a conveying mechanism and a dehumidifying mechanism, wherein a controller is fixedly arranged at one end of the drying box body, the other end of the drying box body is connected with the conveying mechanism, a driving cavity and a drying cavity are separately arranged in the drying box body, and a guide plate is connected above one end of the drying cavity; a baffle is fixedly arranged at the bottom of the drying cavity, and a first discharging chute and a second discharging chute are arranged at the two sides of the baffle; an air return hood is fixedly arranged above the first discharging chute; the drying mechanism is arranged in the drying cavity between the guide plate and the air return hood; and the dehumidifying mechanism is connected to the outer part of the drying box body. The efficient grain drying machine related to the invention has the advantages that wet bonded grains can be effectively scattered through the swing of a drying framework, grain gathering is avoided, and the drying rate of the grains is increased; and high-temperature air can be effectively pumped out through an air pump, the grains in a feeding barrel are preheated, the heating and drying time of the grains is reduced, and the practicability is high.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a high-efficiency grain dryer. Background technique [0002] At present, in the field of agriculture, people often need to dry the grain. The traditional drying method is to flatten the grain on the ground and evaporate the moisture in the grain through the sun's radiation, but this method is extremely susceptible to the influence of the environment, and the drying rate is low. With the emergence of the grain dryer, the traditional The drying method began to be replaced. [0003] A grain drying chamber and a grain drying machine are disclosed in the patent application publication number CN 106338195 B, which relates to the field of agricultural machinery. The grain drying room includes a grain drying area, a grain collection area, an air net system and an air isolation device. The grain drying area includes a plurality of parallel hot air passages and cooling air passages...

AI Technical Summary

Problems solved by technology

The air separation device separates the grain drying area from the grain collection area, preventing the negative pressure formed by the wind network system from being transmitted to the conveying device and hoist in the grain collection area; Separate, and reduce the abrasion between the grains by setting the wind net system, but it has the following disadvantages: the grains have a certain degree of moisture before drying, and the above application cannot solve the problem of unity of the grains due to moisture during the drying process, which is extremely It is easy to make the agglomerated grains unable to be fully dried, reducing the uniformity of grain drying, thereby affecting the drying efficiency of grains, and in this application, hot air channels and cold air channels are used alternately, and the heat energy generated during the grain drying process cannot be recycled, which is very easy to cause The loss of heat energy and lowering the drying temperature will not only affect the drying efficiency of the grain, but also increase the energy consumption and the cost is high
