Double-body grain bin capable of distributing grains uniformly

Abstract

The invention discloses a double-body grain bin capable of distributing grains uniformly. The bin comprises a double-body warehouse and a grain discharge device. The double-body warehouse is provided with a first warehouse and a second warehouse. One self-rotating type grain distributor is arranged in each of the first warehouse and the second warehouse. The grain discharging box comprises a grain discharge box and a driving device. The grain discharge box comprises a box body, a first auger, a second auger, a first material inlet, a second material inlet, a discharge port and a belt pulley. The first auger comprises a first rotary shaft, a first spiral plate and a first one-way overrunning clutch. The second auger comprises a second rotary shaft, a second spiral plate and a second one-way overrunning clutch. The first spiral plate and the second spiral plate are opposite in spiral directions. The first one-way overrunning clutch and the second one-way overrunning clutch are arranged in shaft holes of the belt pulley. The lock-up directions of the first one-way overrunning clutch and the second one-way overrunning clutch are opposite. The double-body grain bin capable of distributing grains uniformly has the following beneficial effects: grains can be uniformly distributed; and two kinds of grains are stored; and manufacture cost is low.

[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

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

In addition, most of the current traditional granaries adopt a single-body design, which can only store one kind of grain at the same time, and has a single function

There are also some granaries that adopt a double-body design, but use two separate sets of unloading devices to unload grain separately, resulting in the disadvantages of occupying a large area and high cost
