Self-unloading twin granary with more uniform grain distribution

Abstract

The invention discloses a self-unloading twin granary with more uniform grain distribution. The self-unloading twin granary comprises a twin warehouse body and a grain unloading device; the twin warehouse body is provided with a first warehouse and a second warehouse; self-rotating grain distributors are respectively arranged in the first warehouse and the second warehouse; the grain unloading device includes a tank with a first grain unloading cavity and a second grain unloading cavity, a first auger for unloading grains stored in the first grain unloading cavity, a second auger for unloading grains stored in the second grain unloading cavity, and a driving device for driving the first auger and the second auger to rotate; the first auger includes a first rotating shaft, a first spiral plate and a first driven gear; the second auger includes a second rotating shaft, a second spiral plate and a second driven gear; the driving device includes a driving motor and a clutch linkage device; the clutch linkage device includes a frame body, a transmission shaft, a clutch transmission gear, a belt wheel and a translation limiting piece; and the clutch transmission gear is screwed on an external thread part of the transmission shaft. The self-unloading twin granary is more uniform in grain distribution, can store two types of grains, and is lower in manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of granary structure design, and in particular relates to a self-unloading double-body granary with relatively uniform grain distribution. Background technique [0002] Modern grain logistics requires fast grain entry and exit. At present, modern large-scale modern granaries, mainly shallow round silos and vertical silos, have the advantages of relatively small footprint, large storage capacity, and high degree of mechanization, which greatly speeds up the grain transportation. The speed of entering and exiting the silo; however, because the shallow round silo and the vertical silo have only one grain inlet at the top, and the grain inlet is tens of meters away from the ground, when the grain is fed, due to the different physical properties of the impurities and grain particles, it will cause serious grain automatic failure.

[0002] Modern grain logistics requires fast grain entry and exit. At present, modern large-scale modern granaries, mainly shallow round silos and vertical silos, have the advantages of relatively small footprint, large storage capacity, and high degree of mechanization, which greatly speeds up the grain transportation. The speed of entering and exiting the silo; however, because the shallow round silo and the vertical silo have only one grain inlet at the top, and the grain inlet is tens of meters away from the ground, when the grain is fed, due to the different physical properties of the impurities and grain particles, it will cause serious grain automatic failure. The grading phenomenon leads to the mineral impurity area, especially the impurity cylinder area at the center of the circle, and the light impurities float to the surroundings to form an annular light impurity area around, especially the impurity cylinder area at the center of the circle. Due to a large amount of dust and broken grains, the grain The pile porosity is very small, which affects grain ventilation, cooling, precipitation, fumigation and insecticide, and impurities carry a large number of microorganisms, which seriously affects the safe storage of grain

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
