If the pipe distribution is dense, the grain storage capacity of the granary will be reduced, and the construction cost of the granary will be increased, that is, the cost of the staff laying the granary cooling equipment will be increased.

DETAILED DESCRIPTION

[0023] In order to better understand the utility model, the content of the utility model is further illustrated below in conjunction with examples, but the content of the utility model is not limited to the following examples.

[0024] As Figs. 1-2 As shown in a kind of grain storehouse that can be uniformly cooled, same as prior art, including grain storage cylinder 3 and the support leg 1 of the bottom of grain storage cylinder 3, grain storage cylinder 3 top is equipped with the grain inlet cylinder 5 for sending grain into grain storage cylinder 3 and store, grain inlet cylinder 5 top is equipped with the cover for blocking grain inlet cylinder 5, support leg 1 is used to fixedly bear grain storage cylinder 3 to a certain height, to make the grain discharging cylinder 203 arranged in the bottom of grain storage cylinder 3 leak, and grain discharging cylinder 203 corresponds with the multiple grain discharging holes 7 opened in the bottom of grain storage cylinder 3, to facilitate staff to take out the grain stored in grain storage cylinder 3.

[0025] Different from the prior art, a plurality of ventilation holes 8 are uniformly arranged on the outer periphery of the grain storage cylinder 3, a suction cylinder 605 is arranged at the center of the grain storage cylinder 3, a fixed frame 601 is fixedly arranged on the upper side of the grain storage cylinder 3, a driving motor 602 is arranged at the center of the fixed frame 601, a driving shaft 603 is fixedly connected to the output shaft of the driving motor 602, the bottom of the driving shaft 603 is rotatably arranged on the inner wall of the bottom of the grain storage cylinder 3 through the suction cylinder 605, and a fan blade 604 is arranged in the suction cylinder 605 on the outer periphery of the driving shaft 603. When the driving motor 602 operates, the driving shaft 603 and the fan blade 604 rotate to generate an exhaust force in the suction cylinder 605 to exhaust air outward, and the grain storage cylinder 3 is relatively closed except the plurality of ventilation holes 8. Therefore, the cooling air from the outside enters the suction cylinder 605 through the ventilation holes 8, and then passes through the stored grain between the grain storage cylinder 3 and the suction cylinder 605 to cool the stored grain.

[0026] The ventilation holes 8 are arranged in multiple groups and uniformly arranged on the outer periphery of the grain storage cylinder 3 in the vertical direction. Any group of ventilation holes 8 is uniformly arranged around the grain storage cylinder 3. The plurality of ventilation holes 8 can divide the stored grain into multiple layers, and then cool the bottom of each layer of stored grain. Then, the overall uniform cooling of the stored grain can be achieved through heat transfer between the relatively thin layers of stored grain.

[0027] The fan blade 604 is arranged in a spiral shape. The spiral-shaped fan blade 604 can push air to be discharged at high speed above the suction cylinder 605. Then, the force of the suction cylinder 605 for sucking air from the outside through the ventilation holes 8 is improved, and the strength of the cooling air passing through the stored grain between the suction cylinder 605 and the grain storage cylinder 3 is improved. In this way, the effect of ventilation and cooling of the stored grain can be improved.

[0028] The grain storage cylinder 3 is arranged in a screen cylinder, and the mesh of the grain storage cylinder 3 is arranged in a downward inclination. The downward inclined mesh can reduce the probability of grain storage, and can make the grain storage stably displace downward for discharge or storage accumulation.

[0029] A plurality of groups of ventilation holes 8 are each provided with a rain guide ring 4 fixedly arranged on the outer periphery of the grain storage cylinder 3. Specifically, the rain guide ring 4 is in a skirt shape, that is, the cross section is arranged in an inclination away from the grain storage cylinder 3. In this way, the rain guide ring 4 can guide rainwater to be discharged outside the grain storage cylinder 3, so as to reduce the probability of rainwater or sundries entering the ventilation holes 8, and also can maintain the stability of the air inlet of the ventilation holes 8 in rainy and snowy weather.

[0030] The end of the rain guide ring 4 away from the grain storage cylinder 3 is fixedly provided with a positioning ring 402, and a moisture-proof ring 401 is clamped between the positioning ring 402 and the grain storage cylinder 3. The moisture-proof ring 401 can absorb the moisture in the air flowing into the ventilation holes 8 due to the suction force, so as to reduce the influence of the moisture in the air on the stored grain.

[0031] The bottom of the grain discharging cylinder 203 is provided with a grain blocking plate 202, the grain blocking plate 202 is provided in an inclined shape with one end being higher and the other end being lower, and the higher end of the grain blocking plate 202 penetrates out of the grain discharging cylinder 203 and is fixedly provided with a pulling handle 201, when the inclined grain blocking plate 202 is pulled, the weight of the grain borne by the grain blocking plate 202 will be separated into two inclined forces, one part of the force will be borne by the grain discharging cylinder 203, thereby the force required for pulling the inclined grain blocking plate 202 relative to the horizontally arranged grain blocking plate 202 is lower, so that the staff can conveniently pull to carry out the grain discharging operation, specifically, the pulling handle 201 is arranged correspondingly to the interval of the grain storage cylinder 3, so as to facilitate the staff to operate to pull out the grain blocking plate 202 to carry out the grain discharging.

[0032] The specific embodiments of the present application are described above. It should be understood that the present application is not limited to the specific embodiments described above, and various modifications or changes can be made by those skilled in the art within the scope of the claims, which does not affect the essential content of the present application.
