Electric grain-unloading granary capable of distributing grains uniformly

Abstract

The invention discloses an electric grain-unloading granary capable of distributing grains uniformly. The electric grain-unloading granary comprises a double-body warehouse and a grain unloading device, wherein self-rotating grain distributors are respectively arranged in a first warehouse and a second warehouse; the grain unloading device comprises a first auger, a second auger and a drive device; the drive device comprises a drive motor provided with a drive wheel, and a linkage switching device; the linkage switching device comprises a rack body, a transmission wheel group, a guiding plate and a linkage gear assembly; the transmission wheel group comprises a transmission shaft, a transmission belt wheel and a transmission gear; a guiding hole is formed in the guiding plate; the linkage gear assembly comprises a linkage gear and a guiding element for limiting the linkage gear to slide along the guiding hole in a reciprocating way; the guiding element is located in the guiding hole; when the guiding element slides to one end of the guiding hole, the transmission gear drives a first driven gear to rotate through the linkage gear; when the guiding element slides to the other end of the guiding hole, the transmission gear drives a second driven gear to rotate through the linkage gear. The electric grain-unloading granary capable of distributing the grains uniformly provided by the invention can be used for distributing the grains uniformly and storing two species of grains, and has lower 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
