Self-rotating grain distribution device for granaries

Abstract

The invention discloses a self-rotating grain distribution device for granaries. The self-rotating grain distribution device comprises a bearing block, a rotating shaft and a grain distribution part, the rotating shaft is rotatably arranged on the bearing block, the grain distribution part is fixedly arranged on the rotating shaft, the rotating shaft is arranged along the plumb line direction, the grain distribution part comprises a grain collection area, a plurality of grain sliding arms and a plurality of guide plates, each grain sliding arm comprises a bottom plate, a first side plate and a second side plate, the bottom plate, the first side plate and the second side plate of each grain sliding arm enclose into a grain sliding channel, each first side plate and each second side plate are positioned on two side ends of the corresponding bottom plate, the first side plates and the second side plates are linear plates and arranged along the plumb line direction, each bottom plate is obliquely arranged downwards along the direction from the corresponding second side plate to the corresponding first side plate, six grain discharging ports are formed in the bottom wall of the grain collection area, one end of each guide plate is fixedly arranged on the bottom wall of the grain collection area or the bottom plate of the corresponding grain sliding arm, and the other end of the guide plate obliquely extends downwards below the corresponding grain discharging port. The self-rotating grain distribution device can automatically rotate, and grains are uniformly distributed.

[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
