High-tower-shaped grain drying machine

Abstract

The invention discloses a high-tower-shaped grain drying machine, and belongs to the technical field of agricultural equipment. The high-tower-shaped grain drying machine aims to enable to-be-dried grains to be subjected to even drying treatment. The high-tower-shaped grain drying machine comprises a base arranged on the ground surface, supporting frames arranged on the base, two mutually parallelgrain storage boxes arranged on the upper portions of the supporting frames, a control module arranged on the outer portion of the corresponding grain storage box, a collecting bucket arranged on thelower portions of the grain storage boxes, a drying module arranged on the lower portion of the collecting bucket, a grain outlet channel formed in the lower portion of the drying module and a grainextraction device arranged by the side of the grain outlet channel to communicate with the grain outlet channel, revolving doors are arranged at the lower ends of the grain storage boxes, and rotatingmotors are arranged on the revolving doors; and the rotating motors are connected with the control module through wires, the two grain storage boxes are mutually parallel, and the high-tower-shaped grain drying machine has the beneficial effects that the drying frequencies and time of all grains are equal, even drying is ensured, and insufficient drying or excessive drying of partial grains cannot be caused.

Description

technical field [0001] The invention belongs to the technical field of agricultural equipment, and relates to a grain dryer, in particular to a high-tower grain dryer. Background technique [0002] After harvesting, the moisture content of the grain is generally very high. In order for the grain to meet the conditions for safe storage (no mildew), the moisture content of the grain must be reduced to a safe moisture level for storage. In order to protect the grain, the grain drying speed should not be too fast. Too fast will easily lead to microscopic cracks on the surface of grain particles, which will directly affect the yield and economic value of the grain. Among them, the drying of rice not only requires high productivity, low burst rate, but also a high whole rice rate. The whole rice rate when drying rice is not only related to the medium temperature but also has a certain relationship with the relative humidity of the air. When the hot air temperature increases, the...

Problems solved by technology

However, the existing grain dryer basically has only one grain storage device, and the degree of grain drying is controlled by controlling the time, so that when it is finally stopped, it is easy to cause the drying times of some grains in the grain storage device to be less than other grains, and eventually Insufficient drying of some grains or excessive drying of some grains
