Self-rotation grain distribution device

Abstract

The invention discloses a self-rotation grain distribution device comprising a bearing pedestal, a rotating shaft and a grain distribution piece, wherein the rotating shaft is arranged in the direction of a plumb line; the grain distribution piece comprises a grain collection area and a plurality of grain sliding barrels; the grain collection area comprises an annular plate, a round bottom wall, and a plurality of evolvent plates; the rotating shaft is positioned at the center of the round bottom wall; the two adjacent evolvent plates are combined in a clamping manner to form a flowing guiding channel; a plurality of grain outlets are formed in the annular plate; each grain outlet just faces a corresponding flowing guiding channel; each grain sliding barrel is fixedly arranged at the peripheral wall of the annular plate; each grain sliding barrel is communicated with one grain guiding channel by a corresponding grain outlet; each grain sliding barrel is arranged in an inclined manner in a direction from top to bottom; a self-rotation stress surface is arranged at the top end of each evolvent plate and is an inclined surface inclined downwards or an arc-shaped surface; and a grain falling opening is formed in the bottom wall of each flowing guiding channel. In the invention, the self-rotation performance can be realized, and the grain distribution is relatively uniform.

[0002] Modern grain logistics requires that grain enter and exit the warehouse quickly. The state has invested in the construction of large-scale modern grain warehouses, mainly shallow round warehouses and vertical silos. These two warehouse types have relatively small footprints, large storage capacity, and mechanized The advantages of high degree greatly speed up the speed of grain entering and leaving the warehouse; however, since the shallow round warehouse and the vertical silo have only one grain inlet at the top, and the grain inlet is tens of meters away from the ground, due to the physical properties of impurities and grain particles Different, it will cause serious automatic grading of grain and miscellaneous impurities, resulting in mineral impurities, especially the impurity cylinder area at the center of the circle, and light impurities floating to the surroundings to form a ring-shaped light impurity area, especially the impurity cylinder at the center of the circle. Due to a large amount of dusty and broken grains, the voids in grain piles are very small, which affects grain ventilation, cooling, precipitation, fumigation and insecticide, and a large number of microorganisms carried by impurities seriously affect the safe storage of grains.

This area is often hot, moldy, and agglomerated during grain storage, which seriously affects the safety of grain storage and increases the workload of grain storage

[0003] In order to reduce the accumulation of impurities caused by automatic grading caused by excessive concentration of grain from one grain inlet, certain measures are also taken at present, such as setting a conical hood under the grain inlet, so that the grain flowing into the grain inlet is along the slope of the conical hood. Move a certain distance outside to disperse the concentrated falling of the grain, but this method can only change the grain into a ring from a point, and there will still be an impurity ring area under the conical mask mouth, which cannot effectively eliminate the accumulation of impurities , due to the poor effect, it is rarely used at present, and has not been promoted so far
