Lightweight grain dryer

Abstract

The invention discloses a lightweight grain dryer. The lightweight grain dryer comprises a feeding hopper and a rotary drum. The feeding hopper is connected with the rotary drum through a grain inlet of a spiral rotating shaft. Supporting rotating shafts are arranged on the two sides of the rotary drum. The hollow part inside the rotary drum is arranged to be a drying area. A stirring disc is installed inside the drying area. A rotating motor is arranged on the outer side of the rotary drum. A heat inlet of the rotary drum is connected with a heater through a heat-conducting pipe. A cooling hole of the rotary drum is connected with a cyclone discharger. One side of the cyclone discharger is connected with a dampness outlet through a draught fan, and the other side of the cyclone discharger is connected with a discharging hopper. Fresh grains are filtered to enter the rotary drum directly, are stirred in the rotary drum to be dried and turn over when stirred, heat can be effectively utilized, moisture in the grains can be sufficiently evaporated, dampness in the grains can be conveniently discharged, and the grain drying quality can be improved. Thus, the lightweight grain dryer is an excellent innovation scheme and has broad market promotion prospects.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a light grain dryer. Background technique [0002] With the continuous development of modern society, people's living standards have also been improved day by day, especially for farmers who face the loess and their backs to the sky, they have indeed undergone great changes in farming. With various farming tools With the emergence of the invention, people's farming operations have become much easier. It can save people a lot of manpower, material resources and financial resources, make farming all enter the modernization, have more time for other activities, and improve people's physical and mental cultivation. [0003] As we all know, the water content of fresh grains is far greater than the safe water stored.

[0003] As we all know, the water content of fresh grains is far greater than the safe water stored. If they are not air-dried in time, or in bad weather, the grains are prone to mold and deterioration, so they need to be dried. The method of drying is to spread the grains on the ground , Evaporate water through direct sunlight, which is the most traditional operation method, but this method is inefficient, requires a lot of manpower, and is quite laborious. Although there are some dryers, the flexibility of use is not good, and the air-drying effect Not good, the heat energy utilization rate is low, the hot air effect is not good, etc., the fresh grain cannot be air-dried very effectively, resulting in the moisture of the grain not meeting the storage requirements, and the heat is greatly consumed, the energy saving is poor, and there are deficiencies that cannot be met. social development needs
