Grain drying and screening integrated device

Abstract

The invention discloses a grain drying and screening integrated device. The grain drying and screening integrated device comprises a case, a spreading device, an air heater, a screening box and an impurity box. The spreading device is arranged in the case. Two horizontal sliding rods are arranged in the case. The two ends of each sliding rod are welded to the inner wall of the case. The screeningbox is slidably mounted between the two sliding rods. A first screen, a second screen and a third screen are sequentially arranged in the screening box from top to bottom. Compared with an ordinary spreading device, a flat spreading plate is indirectly driven by a driving motor to move left and right so that grain can be evenly spread on a conveying belt, the situation that the grain is accumulated in the feeding process, and consequentially, the drying effect is affected is prevented; the screening box moves left and right in the screening process, so that the flow rate of the grain in the screening box is improved, and the screening speed is improved; and meanwhile, a first screen, a second screen and a third screen are arranged in the screening box, so that grain with various sizes is separated, secondary operation is not needed, and the screening time is shortened.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a grain drying and screening integrated device. Background technique [0002] "Grain" covers a wide range, including rice, wheat, millet, soybeans, etc. and other miscellaneous grains. Cereals include rice, wheat, millet, soybeans, etc., mainly plant seeds and fruits. It is a traditional staple food of many Asian peoples. Cereals do not only refer to the seeds of gramineous plants. To be precise, they can be roughly divided into three categories in my country: ① Cereals: including rice (indica rice, japonica rice, rice), wheat (wheat, barley, oats, rye) ), corn, sorghum, millet, millet, yellow rice, buckwheat, etc.; ②beans (shū): including soybeans, broad beans, peas, mung beans, red beans, kidney beans, etc.; ③potatoes: including sweet potatoes, also known as sweet potatoes or sweet potatoes , potato, yam, taro, cassava, etc. [0003] When drying and screening grains, the drying eff...

AI Technical Summary

Problems solved by technology

[0003] When drying and screening grains, the drying effect is often poor due to the accumulation of grains, and the screening speed is slow during screening and it is impossible to separate multiple specifications of grains at one time
