Description

Technical Field

[0001] The utility model relates to the technical field of grain drying, in particular to a grain drying device. Background Art

[0002] Grain is a living organism, and water is the condition for its survival. However, too much water will induce the growth of insects and microorganisms, and easily cause grain to heat up, ferment, deteriorate and germinate. Take wheat as an example. The moisture content at harvest is between 25% and 40%. When storing, it needs to be reduced to below the safe moisture as soon as possible to meet the requirements of safe grain storage. During the wheat harvest season, in order to avoid the influence of rainy weather, the wheat should be harvested and dried as soon as possible and put into storage. However, due to the limitation of drying space, the stored grain often cannot be dried on time, so it is necessary to rely on drying equipment to dry the wheat as soon as possible.

[0003] In the existing grain drying equipment, part of the heated air is discharged to the outside of the equipment during use, resulting in heat loss, which is not convenient for efficient drying of grains. Some wheat bran and straw will inevitably remain in the wheat. The existing grain drying equipment is not convenient for removing the straw from the grain, and the dried grain needs to be cooled to prevent the grain from becoming moldy and deteriorating during storage.

[0029] In order to achieve the effect of high-efficiency drying and blowing away the straw mixed in the grain, the attached Figure 1-3As shown, the present application adopts the following structure, through the cooperation of the first feed pipe 2, the heating wire 15, the air pump 16, the first motor 14, the first sleeve 17, the first hinged leaf 18, the first rotating rod 28, the second hinged leaf 27, the gear 13, the internal gear 12, the second motor 24, the air outlet pipe, the nozzle 23, the buffer plate 19, the slider 21 and the spring 20, during use, the grain is poured into the drying drum 1 from the first feed pipe 2, and then the first control valve 11 is closed by the controller 4, the heating wire 15, the air pump 16 and the first motor 14 are started, and the heating wire 1 5 starts to heat, the air pump 16 blows the heated air into the first sleeve 17, and discharges it through the first air outlet inside the first hinged leaf 18 to dry the grain, and the output end of the first motor 14 drives the first sleeve 17 and the first hinged leaf 18, the first sleeve 17 drives the turntable and the first rotating rod 28, the first rotating rod 28 drives the gear 13 and the second hinged leaf 27 to rotate, the gear 13 and the internal gear 12 mesh and rotate, so that the first rotating rod 28 drives the second hinged leaf 27 to rotate around the first sleeve 17 while rotating around the center of the first rotating rod 28 itself. The line rotates, thereby fully stirring the grain and efficiently drying the grain. After drying for a period of time, hot air will accumulate on the top of the drying cylinder 1. The hot air passes through the circulation pipe 3 and enters the interlayer between the drying cylinder 1 and the annular partition. The air inside the drying cylinder 1 is circulated and heated to keep the drying cylinder 1 warm and reduce heat loss. Then the second control valve 26 and the second motor 24 are opened by the controller 4, and the dried grain is discharged from the first discharge pipe 25.
