[0002] As the basic material guarantee for human survival and development, food occupies a vital position in the entire social and economic system. In the process of food production, proper storage of grain is the key link to ensure that the quality and quantity of grain are not lost.

[0003] In traditional grain storage methods, it is difficult to accurately control the internal humidity of many storage devices. Some simple granaries only rely on natural ventilation to adjust the humidity. However, when the humidity of the external environment is high, moisture can easily invade the interior of the storage device, causing the grain to become damp and moldy. In response to the above technical problems, it is urgent to develop a grain storage device for grain production. Summary of the invention

[0013] A ventilation cage assembly, wherein the ventilation cage assembly is connected to the material storage box assembly;

[0014] The disturbance component penetrates the storage box component and is connected with the ventilation cage component, and is used for disturbing and separating grain particles.

At the same time, a plurality of disturbance plates 703 that move back and forth laterally can drive the grain particles inside the storage box 201, change the position of the internal grain particles, and thus increase the gas circulation speed.

[0038] In one embodiment of the present invention:

[0039] A method for storing grains for food production, the method comprising: placing grain particles in batches on the center racks 203 of each layer inside a storage box 201, opening the first driving member 303, forming a negative pressure inside the storage box 201, and synchronously rotating the center rod 402 axially to drive a plurality of groups of disturbance plates 703 to move horizontally back and forth, while achieving the displacement drive of the grain particles on each layer, driving the lateral ventilation grooves 205 of each layer to open periodically, thereby achieving all-round circulation ventilation storage of the grains inside the storage box 201.

[0040] The working principle of the present invention is as follows: the inner wall of the storage box 201 is hollow, a plurality of transverse ventilation grooves 205 are connected and arranged in the inner wall of the storage box 201, and the interior of the storage box 201 is divided into a plurality of layers by a plurality of intermediate racks 203. A plurality of feeding valves (not shown in the figure) are arranged on the outer side of the storage box 201, and the stored grains are orderly stored in each layer of the storage box 201. Various gases generated by the grains can be exchanged layer by layer and then discharged through the top ventilation top window 202. At the same time, when the disturbance component 7 is running, various gases generated by the grains can also be discharged through the plurality of transverse ventilation grooves 205 and the ventilation cage component 6, so as to realize all-round gas exchange inside the storage box 201. The top side of the wind bin 302 is provided with an opening. When the first driving member 303 is running, it can drive the negative pressure blades 304 to rotate, and negative pressure can be formed inside the air collecting box 301 and the storage box 201, so that the moist or adverse gases inside the air collecting box 301 and the storage box 201 can be quickly and directionally discharged. At the same time, in conjunction with the reducer 305, it can drive the central interlocking component 4 inside the storage box 201 to rotate at a uniform speed. When the first driving member 303 is running, in conjunction with the reducer 305 and the transmission shaft 401, it can drive the central rod 402 and several groups of interlocking plates 404 to rotate synchronously. The rotating interlocking plates 404 can disturb and separate the grain particles in each layer. Several groups of interlocking plates 404 are arranged equidistantly in the longitudinal direction of the central rod 402, and each group of interlocking plates 404 is arranged equidistantly in the axial direction. Four interlocking plates 404 are arranged equidistantly, and the interlocking plates 404 are far away from the central rod 4. One end of 02 is set in an arc shape, and the middle rod 402 drives several groups of joint control plates 404 to rotate at a uniform speed, which can contact the disturbance component 7 periodically, driving the disturbance component 7 to move back and forth periodically laterally. When the driving component 7 moves back and forth laterally periodically, the transverse ventilation groove 205 inside the ventilation cage 601 at the corresponding position can be opened periodically to achieve periodic multi-point exhaust, and the slot diameters of the ventilation top window 202, the longitudinal ventilation groove 204 and the transverse ventilation groove 205 are all smaller than the diameter of the stored grain particles to prevent the grain from being discharged during the ventilation process. The end of the transmission rod 701 away from the ventilation cage 601 is also set in an arc shape. When the elastic member 603 is fully expanded, the baffle frame 702 and the transverse ventilation groove 205 at the corresponding position are away from the middle rod The side of the horizontal ventilation groove 205 is abutted against 402, so as to complete the closure of the horizontal ventilation groove 205 at the corresponding position, and a through groove (not shown) for the horizontal movement of the transmission rod 701 is provided inside the horizontal ventilation groove 205. When the outer end of the rotating joint control plate 404 is in periodic contact with the end of the transmission rod 701 away from the ventilation cage 601, the transmission rod 701 can be periodically driven to move toward the side of the ventilation cage 601, thereby driving the baffle plate frame 702 to separate from the horizontal ventilation groove 205 at the corresponding position, so that the horizontal ventilation groove 205 is connected with the ventilation cage 601 to realize horizontal multi-point ventilation. At the same time, a plurality of disturbance plates 703 that move back and forth laterally can drive the grain particles inside the storage box 201, change the position of the internal grain particles, and thus increase the gas circulation speed.

[0041] In summary, while ensuring the inherent gas fluidity inside the storage box 201, the storage device and method increase the ventilation points inside the storage box 201 through the cooperation of the central linkage control component 4 and the periodic ventilation device 5, forming a three-dimensional ventilation structure inside the storage box 201, preventing the intrusion of humid gas and reducing the possibility of internal grain mold.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
