Grain unloading device for drying box of grain dryer

Abstract

The invention discloses a grain unloading device for a drying box of a grain dryer. The grain unloading device comprises a box body, net plates, a bottom frame, a guide rail and a grain discharging part, the net plates are fixed in the box body and are arranged at the upper part of the box body; the bottom frame is fixedly connected with the box body and is arranged at the bottom of the box body; the guide rail is fixed at the lower part of the box body; the grain discharging part is arranged below the net plates, the two ends of the grain discharging part are fixed to the guide rails, the grain discharging part is further connected with a transmission part, the transmission part is further connected with a motor assembly, the motor assembly provides power, and the transmission part drives the grain discharging part to linearly slide up and down along the guide rail; hot air is used for dehydrating and drying grains from vent holes in the net plates, the grain discharging part reciprocates up and down along the guide rail, the grains are discharged from the gap between the grain discharging part and the net plates, the grain discharging process ensures that the grains have enough standing time in the drying section, and the drying effect is improved; no grain residues exist between the net plates, and the equipment cleaning and maintenance workload is reduced; and the grain unloading process depends on the dead weight of grains, and the grain breakage rate is reduced.

Description

technical field [0001] The invention belongs to the field of grain dryers, in particular to a grain unloading device in a drying box of a grain dryer. Background technique [0002] Since 2004, my country's total grain output has achieved twelve consecutive increases. The rapid growth of grain production and the need for storage have also given birth to the demand for grain drying equipment and processing equipment: first of all, the transfer and concentration of land has promoted the scale and intensive operation of agriculture, which can not only increase grain production, but also Moreover, it will also change the way of artificial drying and storage of grain before, leading to an increase in the demand for grain drying and processing; followed by the development of the grain futures market and the continuous increase of grain processing enterprises, leading to the change of the previous practice of selling grain on the spot after harvest. Instead, learn to store and sell...

AI Technical Summary

Problems solved by technology

[0005] 1. During the process of rotating the grain rolling rod, the grain is squeezed and the damage rate is high;

[0006] 2. It is easy to accumulate grain in the grain transfer stick, it is troublesome to clean the equipment, and the maintenance workload is heavy
