Multi-section grain drying device

Abstract

The invention discloses a multi-section grain drying device, and relates to the technical field of drying devices.The multi-section grain drying device comprises a stock bin, a feeding port and a discharging port are formed in the top and the bottom of the stock bin respectively, a supporting frame is arranged at the bottom end of the stock bin, and multiple sets of drying units are sequentially arranged in the stock bin from top to bottom; each group of drying device comprises a tempering layer, a ventilation layer and a drying layer from top to bottom, a fixed plate and a sliding plate are arranged in the tempering layer, a vibration plate is arranged in the ventilation layer, a driving mechanism is arranged in the stock bin, and the driving mechanism drives the sliding plate to slide and drives the vibration plate to vibrate through a transmission mechanism at the same time. Through cooperation of the stock bin, the tempering layer, the ventilation layer, the drying layer, the fixing plate, the sliding plate, the vibrating plate, the driving mechanism and the transmission mechanism, multiple times of tempering, ventilation and drying are achieved in one drying cycle, and therefore grain cracking is prevented, and the drying quality and the drying efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of drying devices, in particular to a multi-stage grain drying device. Background technique [0002] After the grain is harvested, it is generally necessary to store the grain. If the storage time is long, the grain will become moldy or even rotten, resulting in a waste of resources. Therefore, it is necessary to dry the grain before storing it. Drying equipment is needed during the drying process. The popular drying technologies are mainly ultraviolet drying, infrared drying, electromagnetic drying and hot air drying. Each drying technology has its own characteristics and is widely used. In the drying of various mechanical equipment and grain. [0003] Existing multi-stage grain drying devices, such as the Chinese patent application number CN201810402143.3 titled "A Grain Drying Device", discloses a grain drying device, including a drying barrel connected with a horizontal shaft, Rotating blades are conne...

AI Technical Summary

Problems solved by technology

[0004] The disadvantages of the existing technology are: in the existing drying technology, the temperature tends to rise rapidly on the surface of the grain, which leads to uneven heating of the grain during the drying process, which easily causes the grain to burst, affecting the drying quality and causing waste of resources
