Grain pushing layer for grain drying machine

Abstract

The invention discloses a grain pushing layer for a grain drying machine. The grain pushing layer comprises a housing, a grain pushing mechanism and more than one grain separating member, wherein thegrain pushing mechanism is arranged in the housing, the more than one grain separating member is arranged in the housing, the grain separating member is a strip-shaped structural member which is formed in a way that a left baffle and a right baffle are connected and of which the cross section is in an inverted V shape, and a plurality of air holes are respectively formed in the left baffle and theright baffle. The grain separating member is of a triangular structure of which the vertex angle is upward, therefore, when grain falls, the grain can be pushed away by the sharp part of the upper part of the grain separating member so as to achieve a grain dispersing effect, secondly, the air holes are formed in the left baffle and the right baffle, thus, hot air in the drying machine can pass through the air holes from bottom to top so as to act on the grain which falls on the left baffle and the right baffle in the condition that air is sucked by a centrifugal fan at an air outlet of the drying machine so as to form negative pressure, thereby blow-drying and blowing away the grain, and the phenomenon of agglomeration of the grain cannot be generated on the left baffle and the right baffle.

Description

technical field [0001] The invention relates to the field of agricultural equipment, in particular to a grain-discharging layer for a grain dryer. Background technique [0002] Grain dryers are important equipment for drying grains. Existing grain dryers generally include a grain transfer layer, which is used to change the flow rate of grains and disperse grain particles. [0003] In the prior art, the grain distributing layer includes a shell and a grain distributing mechanism arranged in the housing. The grain distributing mechanism generally includes a plurality of grain distributing rollers. The Chinese patent application with application number 201720488106.X discloses a grain dryer dial The strengthened structure of the grain layer also includes grain-discharging channels. Although this grain-dividing layer increases the structural firmness, for grains with high water content, the theoretical grain artesian angle cannot make the grains flow downward at all, and it will...
