[0026] The grain unloading device 2 includes a sealing baffle 22, which is fixedly connected to the inner wall of the grain storage tank 1. By arranging the sealing cover 8 and the sealing baffle 22, moisture in the outside air will not enter the grain storage tank 1, so as to ensure that the air in the grain storage tank 1 is dry, and further prevent the grain from becoming moldy. Two weighing columns 25 are arranged above the sealing baffle 22, and the bottoms of the two weighing columns 25 are fixedly connected to the top of the sealing baffle 22, and the tops of the two weighing columns 25 are fixedly connected to the bottom of the holding plate 21, and the holding plate 21 is slidably connected to the inner wall of the grain storage tank 1, and the bottom of the holding plate 21 is fixedly connected to the electromagnetic valve 23, and the bottom of the electromagnetic valve 23 is fixedly connected to the top of the grain unloading port 24, and the bottom of the grain unloading port 24 is slidably connected to the sealing baffle 22. The conveying device 7 includes a conveying pipe 72, and the top of the conveying pipe 72 is fixedly connected to the bottom of the grain storage tank 1, and the right end of the conveying pipe 72 is fixedly connected to the motor 71, and the output shaft of the motor 71 passes through the conveying pipe 72 and the auger 7 3 is fixedly connected, the auger 73 is adapted to the conveying pipe 72. When the device is used to unload grain, the solenoid valve 23 is opened by the controller, and the grain flows into the grain unloading port 24 along the inclined surface of the holding plate 21, and leaks into the funnel-shaped space at the bottom of the grain storage tank 1. The weighing column 25 has a weighing function and supports the holding plate 21. It can accurately weigh the weight of the grain above the holding plate 21 and display it in real time through the controller, which is convenient for the staff to control the amount of grain unloaded at one time. The grain in the funnel at the bottom of the grain storage tank 1 flows into the conveying device 7 along the inclined surface. When a large amount of grain is unloaded at one time, the auger 73 rotates and slowly stirs the grain in the funnel at the bottom of the grain storage tank 1, and swallows it into the conveying device 7 to prevent excessive grain from blocking the discharge port. The blades of the auger 73 push the grain to move horizontally to the left in the conveying pipe 72 through friction and extrusion with the grain, and push it out from the opening at the seat end of the conveying pipe 72, avoiding direct dumping and causing grain damage.

[0027] The operating steps of the utility model are:

[0028] When using the device to store grain, the grain is placed in the grain transport hopper 61, the double-axis motor 42 is started to drive the winding wheel 41 to reel in the traction rope 43, and the grain release device 6 is pulled upward. After the grain release device 6 rises to the top, the double-axis motor 42 is locked, and the servo motor 67 is started to drive the driving wheel 68 to rotate. Under the cooperation of the driven wheel 66 and the connecting shaft 65, the overturning rod 62 rotates, and the grain transport hopper 61 begins to overturn and dump the grain. After all the grain is dumped into the grain storage tank 1, the servo motor 67 and the double-axis motor 42 are reversed to reset the grain release device 6. When the device is used to unload grain, the solenoid valve 23 is opened by the controller, and the grain moves along the inclined surface of the receiving plate 21. The surface of the grain flows into the grain unloading port 24 and flows down into the funnel-shaped space at the bottom of the grain storage tank 1. The weighing column 25 can weigh the change in the weight of the grain in the grain storage tank 1 and display it through the controller, so that the staff can control the amount of grain unloading. The auger 73 rotates and slowly stirs the grain in the funnel at the bottom of the grain storage tank 1 to prevent blockage, and slowly swallows it into the conveying device 7 and pushes it out from the opening at the seat end of the conveying pipe 72, avoiding direct dumping and causing damage to the grain. When the grain is stored in the grain storage tank 1, the fan 3 will ventilate and dehumidify the interior of the grain storage tank 1. At the same time, the sealing structure ensures that moisture in the outside air will not enter the grain storage tank 1 to prevent the grain from mildewing.
