Description

Technical Field

[0001] The utility model relates to the technical field of grain storage, in particular to a grain storage box. Background Art

[0002] Grain refers to the general term for various plant seeds used in cooking food. It is an important material basis for human survival and development. It mainly includes cereals (such as wheat, rice, corn, etc.), beans and potatoes. Grain crops are rich in nutrients. By processing grain in grain processing plants, raw grains can be converted into semi-finished grains and finished grains. Grain plays a vital role in ensuring people's food and clothing, providing energy and nutrition. At the same time, grain production is also an important part of agriculture and is of great significance to the country's economy and social stability.

[0003] When processing in a grain processing plant, a large amount of grain needs to be stored separately. When using existing storage boxes, grains with similar temperature and humidity are usually directly piled in the box, and the grains cannot be subsequently broken up and dried. The grains piled at the bottom cannot be turned over, which will eventually cause moisture, mold, and form large lumps, affecting subsequent processing technology. In view of this, the present application proposes a grain storage box. Utility Model Content

Through the fixation of the two clips, the lower surface of the top cover can maintain close contact with the box body, thereby avoiding the loss of grain due to the tipping over of the box body during subsequent processing or transportation.

[0008] As a further preferred embodiment of the present technical solution, a sealed bearing is sleeved on the output shaft of the motor, and the sealed bearing is arranged at the connection between the motor output shaft and the housing. Through the limiting effect of the sealed bearing, a dynamic seal is formed with the bottom side wall of the housing during the rotation of the output shaft of the motor, thereby reducing the wear between the motor output shaft and the side wall of the housing and preventing grain from falling due to the gap at the connection.

Under the transportation of the conveying pipe and the spiral blades, the grain accumulated at the bottom of the box body is transported to the top, so as to avoid the fermentation of the grain at the bottom due to the influence of temperature and humidity during storage, resulting in the deterioration of the grain. At the same time, during the transportation process, the grain can be dried by contact with the hot air blown by the fan and the fan blades, so as to avoid the moisture and agglomeration of the grain inside the box body, thereby improving the storage quality.

[0014] (2) The utility model can fully disperse the stored grains in the box body by means of a plurality of support plates arranged on the inside of the box body, thereby reducing the squeezing of grain particles on the inner wall of the box body and avoiding the damage of grain particles which would affect the subsequent processing flow.

[0022] Two buckles 4 are installed on the top cover 3 and the corresponding side walls of the box body 1 , and a handle 5 is fixedly installed on the upper surface of the top cover 3 .

[0023] By fixing the two buckles 4, the lower surface of the top cover 3 can be kept in close contact with the box body 1, thereby avoiding the loss of grain due to the box body 1 tipping over during subsequent processing or transportation.

[0024] The ventilation device includes a fan 6 fixedly mounted on the top cover 3 , an output end of the fan 6 is connected to a fan blade 7 , and the fan blade 7 is arranged in the box body 1 .

[0025] The rotation of the fan blades 7 can blow the hot air inside the fan 6 into the box body 1 to contact the accumulated grains, thereby drying them and preventing the subsequent processing quality from being affected by moisture during storage.

[0026] The output shaft of the motor 9 is sleeved with a sealed bearing 10 , and the sealed bearing 10 is arranged at the connection between the output shaft of the motor 9 and the box body 1 .

[0027] Through the limiting effect of the sealing bearing 10, during the rotation of the output shaft of the motor 9, a dynamic seal is formed with the bottom side wall of the box body 1, thereby reducing the wear between the output shaft of the motor 9 and the side wall of the box body 1 and preventing grain from falling due to the gap at the connection.

[0028] Among them, a hanging shaft is sleeved on the top of the movable rod 14, and the hanging shaft is rotatably connected to the movable rod 14, and the hanging shaft is fixedly connected to the inner wall of the conveying pipe 12 through a connecting rod.
