Lifting device for circulating grain dryer

Abstract

The invention relates to the technical field of grain drying, in particular to a lifting device for a circulating grain dryer. The lifting device comprises a body shell and a lower screw conveyor structure, wherein the lower screw conveyor structure is embedded into the side wall of the body shell, a feed inlet is formed in the body shell, an extension pipe is arranged at the upper end of the bodyshell, the inner wall of the body shell is rotationally connected with two first rollers, and the two first rollers are located on the same vertical line. According to the lifting device, grains falling from a winnowing pan moving on the right side and grains conveyed by the lower screw conveyor structure enter the winnowing pan through a material collecting pipe, a second transmission belt, a collecting frame and a conveying pipe, storage dead corners at the bottom of an elevator are avoided, meanwhile, the lifting device is matched with the lower screw conveyor structure, circulation movement of the grains is achieved, when grains are located in the collecting frame and the conveying pipe, the grains slide down by means of self gravity, a power source is saved, the falling grains are stored through a rubber annular plate and a partition plate, and the grains are prevented from sliding down on the second conveying belt.

Description

technical field [0001] The invention relates to the technical field of grain drying, in particular to a lifting device for a circulation grain dryer. Background technique [0002] Grain is a living organism, and moisture is the condition for its survival. However, excessive moisture will induce the growth of insects and microorganisms, resulting in heat generation, fermentation, deterioration and a decrease in germination rate of the grain. Therefore, when the grain is stored, the grain is dry. Very necessary. [0003] Grain dryers and other equipment are needed to dry grain. The circulating grain dryers on the market include a grain hoist, and the hoist conveys the grain upwards to realize circulation. There is a storage dead angle at the lower end of the existing hoist, and the grain in the dead angle cannot be transported. [0004] In view of the above problems, a lifting device for a circulating grain dryer is designed. Contents of the invention [0005] The object ...

AI Technical Summary

Problems solved by technology

The circulating grain dryers on the market include a grain elevator, which conveys the grain upwards to achieve circulation. There is a storage dead corner at the lower end of the existing elevator, and the grain in the dead corner cannot be transported.
