Abstract

A grain storehouse includes a granary, a grain loading system, and a grain unloading system. The granary includes multiple storages arranged in a network format. The bottom of each storage is a tapered structure with a tapered surface downward, and the bottom of the tapered structure provides a switchable blanking exit. The grain loading system includes a lattice girder structure, a plurality of conveyors and multiple hoppers. The grain unloading system includes at least one conveyor that is located under the blanking exit. The present invention improves the automaticity and efficiency of grain loading and unloading of the grain storehouse, so that the grain can be transferred quickly.

First claim

What is claimed is:

1. A grain storehouse, comprising:
a granary, having multiple storages arranged in a network format used to store grain; the bottom of the storage being a tapered structure with a tapered surface downward, and a switchable blanking exit defined at the bottom of the tapered structure;
a grain loading system, comprising: a lattice girder structure, a plurality of conveyors which correspond to multiple storages, and a plurality of hoppers that correspond to multiple conveyors; the lattice girder fixed on the granary and located above multiple storages; more than one conveyors arranged in line and installed on the lattice girder structure to form at least one path for transferring grain; each hopper located under the one end of the corresponding conveyor for catching the grain which transferred by the corresponding conveyor, and for putting the grain to the corresponding storage or the adjacent conveyor; and
a grain unloading system comprising: at least one conveyor that is located under the blanking exit;
wherein when the grain is started to load into the grain storehouse, all the blanking exits are closed, the grain is passed through the grain loading system and filled the multiple storages in sequence; when the grain is started to unload from the grain storehouse, the corresponding blanking exits are opened; the grain of each storage flow out from the blanking exit to the conveyor;
the hopper is a kind of steering hopper, which is rotationally installed on one end of the corresponding conveyor; the steering hopper rotates to unload the grain to the corresponding storage or the adjacent conveyor;
multiple conveyors comprises a plurality of fixed conveyors and a plurality of moving conveyors; the grain loading system comprises multiple parallel guide rails which are installed on the lattice girder structure; a plurality of fixed conveyors are set on the same side of all guide rails, and are successively connected to form a loading path parallel to the guide rails; each guide rail installs at least one moving conveyor which perpendicular to the guide rail, and the moving conveyor moves in the direction of the corresponding guide rail;
when the grain loading system loads grain into one of the storages under multiple fixed conveyors, the grain loading system transports the grain to the steering hopper close to the storage through at least one fixed conveyor, so as to rotate the steering hopper and unload the grain to the storage.

2. The grain storehouse according to claim 1 , wherein the conveyor is retractable, and the grain at the front end of the conveyor is transmitted to the rear end of the corresponding conveyor through the transmission of the corresponding conveyor; when the conveyor is on the extended sate, the front end of the conveyor is located below the adjacent hopper; when the conveyor is on the constrictive sate, the front end of the conveyor is deviates from the bottom of the adjacent hopper, then the grain in the adjacent hopper is unloaded into the corresponding storage.

3. The grain storehouse according to claim 1 , wherein there is only one grain loading path and it is the shortest path passing through all the storages, one end of the grain loading path is the entrance of the grain; the grain loading system fills all the storages in sequence through the one end of the grain loading path to the other end.

4. The grain storehouse according to claim 1 , wherein when the grain loading system loads grain into one of the storages under the multiple moving conveyors, the grain loading system first transmits the grain to the steering hopper close to the storage and installed on the fixed conveyor through at least one fixed conveyor, and at least one moving conveyors is used to convey grain to the steering hopper corresponding to the storage, so as to rotate the steering hopper corresponding to the storage and discharge grain into the storage.

5. The grain storehouse according to claim 1 , further comprising a real-time monitoring system;
wherein the real-time monitoring system comprises a plurality of temperature and humidity sensors; at least one temperature and humidity sensor is installed at the middle and bottom of the inner wall of each storage; at least three temperature and humidity sensors are arranged in each storage along the center line direction of the storage, and the three temperature and humidity sensors are respectively located at the bottom, middle and top of the storage; the temperature and humidity sensor is used to detect the temperature and humidity of the inner wall and the center line of the storage.

6. The grain storehouse according to claim 5 , wherein the real-time monitoring system further comprises at least one gas sensor; the gas sensor is installed on the top of the inner wall of the storage, and is located above the grain after the storage is filled with grain; the gas sensor is installed on the top of the inner wall of the storage, and is located above the grain after the storage is filled with grain; the gas sensor is used to detect the gas information in the storage.

7. The grain storehouse according to claim 5 , wherein the grain unloading system further comprises:
a plurality of motors that corresponding to the multiple blanking exits;
a plurality of gears that installed in the multiple motor output shafts;
a plurality of lead screws that connected to the multiple gears; and
a plurality of unloading switches that connected to the multiples lead screws;
the unloading switches are in their corresponding blanking exits; the motor rotates to drive the corresponding gear, and drives the corresponding unloading switch to open or close the blanking exit through the lead screw.

8. A grain storehouse, comprising:
a granary, having multiple storages arranged in a network format used to store grain; the bottom of the storage being a tapered structure with a tapered surface downward, and a switchable blanking exit defined at the bottom of the tapered structure;
a grain loading system, comprising: a lattice girder structure, a plurality of conveyors which correspond to multiple storages, and a plurality of hoppers that correspond to multiple conveyors; the lattice girder fixed on the granary and located above multiple storages; more than one conveyors arranged in line and installed on the lattice girder structure to form at least one path for transferring grain; each hopper located under the one end of the corresponding conveyor for catching the grain which transferred by the corresponding conveyor, and for putting the grain to the corresponding storage or the adjacent conveyor; and
a grain unloading system comprising at least one conveyor that is located under the blanking exit;
wherein when the grain is started to load into the grain storehouse, all the blanking exits are closed, the grain is passed through the grain loading system and filled the multiple storages in sequence; when the grain is started to unload from the grain storehouse, the corresponding blanking exits are opened; the grain of each storage flow out from the blanking exit to the conveyor;
