Rotating-type grain distributor and granary provided with grain distributor

Abstract

The invention discloses a rotating-type grain distributor and a granary provided with the grain distributor, and belongs to the technical field of granaries. The rotating-type grain distributor comprises a grain collecting barrel. The grain collecting barrel comprises a barrel wall and a barrel bottom. The outer side of the barrel wall of the grain collecting barrel is provided with two downward-inclined grain sliding pipes. The bottom face and one side face of each grain sliding pipe are curved surfaces which are of an integral structure. When the rotating-type grain distributor is used, the rotating-type grain distributor is arranged at a grain inlet of the granary, after grain enters the grain collecting barrel, the grain flows into the grain sliding pipes, and when the rotating-type grain distributor rotates, the grain sliding pipes rotate along with the rotating-type grain distributor. Due to the fact that the bottom face and one side face of each grain sliding pipe are curved surfaces which are of the integral structure, when the rotating-type grain distributor rotates, under the effect of centrifugal force and tangential force generated by the curved surfaces, the grain is scattered and flows out of the grain sliding pipes, and the grain falls onto a circular cross section of the granary. According to the rotating-type grain distributor, the impurity accumulation caused by automatic grading formed by concentrated falling of the grain is alleviated, and the safe storage of the grain is guaranteed.

[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
