Electronic grain unloading granary with relatively uniform grain distribution

Abstract

The invention discloses an electronic grain unloading granary with relatively uniform grain distribution. The electronic grain unloading granary comprises double warehouses and a grain unloading device, wherein self-rotated type grain distributors are respectively arranged inside a first warehouse and a second warehouse; the grain unloading device comprises a first packing auger, a second packing auger and a driving device; the driving device comprises a driving motor with a driving wheel and a linked switching device; the linked switching device comprises a rack body, a transmission wheel group, guide plates and a toothed gear component; the transmission wheel group comprises a transmission shaft, a transmission belt pulley and a transmission gear; guide holes are formed in the guide plates; the toothed gear component comprises a toothed gear and a guide part for limiting the toothed gear to slide along the guide holes in a reciprocation manner; the guide part is positioned in the guide holes; when the guide part slides to one ends of the guide holes, a first driven gear is driven by the transmission gear to rotate through the toothed gear; when the guide part slides to the other ends of the guide holes, a second driven gear is driven by the transmission gear through the toothed gear. The electronic grain unloading granary is relatively uniform in grain distribution, capable of storing two types of grains, and in addition relatively low in manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of granary structure design, and in particular relates to an electric unloading granary with comparatively uniform grain distribution. Background technique [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 ...

[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
