Electric grain unloading granary with spinning type grain distributors

Abstract

The invention discloses an electric grain unloading granary with spinning type grain distributors. The electric grain unloading granary comprises a double warehouse and a grain unloading device, wherein one spinning type grain distributors is arranged in each of 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 provided with a driving wheel and a linkage switching device; the linkage switching device comprises a frame body, a driving wheel set, a guiding plate and a linking gear component; the driving wheel set comprises a driving shaft, a driving belt wheel and a driving gear; a guide hole is formed in the guide plate; the linking gear component comprises a linking gear and a guiding element for limiting the linking gear in sliding along the guide hole in a reciprocating manner; the guiding element is positioned in the guide hole; when the guiding element slides to one end of the guide hole, the driving gear drives a first driven gear to rotate through the linking gear; when the guiding element slides to other end of the guide hole, the driving gear drives a second driven gear to rotate through the linking gear. The electric grain unloading granary disclosed by the invention is more uniform in grain distribution, is lower in manufacturing cost, and can be used for storing two kinds of grains.

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 a spin-type grain distributor. 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 impurities,...

[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
