Material self-cleaning and recovery device of grain tubular dryer

Abstract

A material self-cleaning and recovery device of a grain tubular dryer belongs to grain drying equipment. An inclination frame is mounted outside a tube hole of one end of an angular tube which is located outside the grain tubular dryer and located on the bottommost layer; a self-cleaning and recovery plate is installed on an upper end inclination part of the inclination frame; triangular conical blocking recovery plates are installed on two side end parts of the self-cleaning and recovery plate and between side wall plates of the grain tubular dryer respectively; triangular conical splitting plates are mounted at a middle part of the self-cleaning and recovery plate, between the side wall plates of the grain tubular dryer and between the adjacent angular tube holes located on the bottommost layer respectively; and a buffering padding plate is paved on the upper end face of the self-cleaning and recovery plate. The device has the beneficial effects that the structure is unique, simple and rational; manufacture cost is low; self-cleaning and recovery effects are good; occurrence of falling damage and species mixing of grains can be effectively avoided and eliminated; operation quality is guaranteed; assisting staffs are reduced; and operation cost is reduced.

Description

technical field [0001] The invention belongs to grain drying equipment, and mainly relates to a material self-cleaning recovery device of a grain tube dryer. Background technique [0002] At present, tubular dryers that use angular tube intake and exhaust to dry grain in parallel, countercurrent, or mixed flow are widely used and are one of the main types of grain drying. However, in the practice of many years of use, it has been found that the drying process of this type of tubular dryer is relatively long. During the process of feeding into the machine, due to the collision between the grain material and the angular tube and the Collisions caused the grain materials to fall from the mouth of the angular tube to the outside of the tube dryer. When they fell to the ground, they could not return to the tube dryer by themselves. Manual cleaning and recycling was usually used, resulting in waste of personnel and production costs. Especially when the dried grain material is see...

However, in the practice of many years of use, it has been found that the drying process of this type of tubular dryer is relatively long. During the process of feeding into the machine, due to the collision between the grain material and the angular tube and the Collisions caused the grain materials to fall from the mouth of the angular tube to the outside of the tube dryer. When they fell to the ground, they could not return to the tube dryer by themselves. Manual cleaning and recycling was usually used, resulting in waste of personnel and production costs. Improvement, especially when the dried grain material is seeds, the falling seed material is easy to be injured, and it is easy to cause the phenomenon of mixed species, which affects and reduces the quality of the seeds
