the bottom end of the inner wall of the containing groove 2 is inclined, and one side close to the square discharging pipe 5 is lower, so that grains can conveniently enter the square discharging pipe 5;

when the grain in the holding tank 2 is not enough, an operator grasps the knob 702 and manually rotates the knob 702, the knob 702 moves to drive the driving shaft 7 fixedly connected with the knob 702 to rotate, the driving shaft 7 is rotatably connected with the inner wall of the storage tank 1, the driving shaft 7 rotates to drive the stirring blade 701 fixedly connected with the driving shaft 7 to rotate, and the grain in the holding tank 2 is stirred through the rotation of the stirring blade 701, so that the grain moves towards the direction close to the square discharge pipe 5;

when part of grains remain, an operator grasps the outer side of the storage box 1, the storage box 1 is manually inclined, so that the grains can flow out of the square discharge pipe 5, or the sealing cover 3 is directly opened, and the grains in the accommodating groove 2 are taken out or new grains are added;

meanwhile, in the process of storing grains in high-temperature weather, the grains need to be ventilated and cooled, an operator grasps the knob 702 and manually rotates the knob 702, the rotation of the knob 702 can drive the driving shaft 7 and the stirring blades 701 to rotate, the rotation of the driving shaft 7 can drive the chain wheel fixedly connected with the driving shaft 7 to rotate, the rotation of the chain wheel can drive the connecting rope 810 meshed with the chain wheel to slide, the movement of the connecting rope 810 is guided through the action of the sliding rail 812, the outer side of the chain wheel is sleeved with the circular protection box fixedly connected with the inner wall of the movable groove 801, the driving shaft 7 extends out of the circular protection box and is rotatably connected with the circular protection box, the circular protection box extends out of two ends of the connecting rope 810 and is slidably connected with the circular protection box, and the possibility that the grains influence on the movement of the chain wheel and the connecting rope 810 is reduced;

meanwhile, when the driving shaft 7 rotates counterclockwise, the block 809 moves towards the direction close to the air bag 802, the two springs 811 are both stretched, at this time, the two sliding blocks 806 slide towards the direction close to the air bag 802, so as to drive the extrusion block 807 fixedly connected with the sliding blocks 806 to move, the sliding of the sliding blocks 806 is guided by the action of the guide rod 805, the extrusion block 807 extrudes the air bag 802, the air pressure inside the air bag 802 increases, the air blows the first sealing plate 814 to rotate, the first sealing plate 814 does not seal the first through groove 813, at this time, the air enters the exhaust pipe 803 through the first through groove 813, and then enters the accommodating groove 2 through the exhaust pipe 803, and at the same time, the air pressure inside the air bag 802 increases, so that the second sealing plate 815 tightly seals the second through groove 816;

when the driving shaft 7 rotates clockwise, the spring 811 rebounds, the two sliding blocks 806 move in the direction away from the air bag 802, when the sliding blocks 806 do not extrude the air bag 802, because the air bag 802 has a rebounding effect, the air pressure in the air bag 802 is reduced at the moment, the outside air blows the second sealing plate 815 to rotate through the air inlet pipe 804, the second sealing plate 815 does not seal the second through groove 816, the air enters the air bag 802 through the second through groove 816 to fill the air bag 802 until the air pressure in the air bag 802 is balanced with the outside air pressure, and the second sealing plate 815 seals the second through groove 816;

meanwhile, the rotation of the driving shaft 7 and the stirring blades 701 can stir grains continuously, so that the grains are convenient to ventilate, the airtight plate 901 is drawn out from the slide 902, the gas in the accommodating groove 2 is convenient to discharge, under the condition that a plurality of layers of the devices are stacked, the grains in the devices can be ventilated and cooled without moving the stacked devices away, the possibility that the grains adsorb vapor in the air is reduced, and the storage resistance of the grains is improved;

bin 1 is made of transparent plastic, so that the operator can observe the amount of grains in bin 1.

The air inlet pipe 804 is provided therein with a moisture absorbent for absorbing moisture from the outside air, the moisture absorbent is located outside the storage box 1, and the moisture absorbent is easy to replace, which is the using process of the grain storage device, and the content not described in detail in this specification belongs to the prior art known to those skilled in the art.
