1. the grain feeding equipment is checked and the fan 140 is started.
2. The external grain feeding equipment is started in sequence, grains enter the grain receiving hopper 110 through the grain feeding opening of the squat silo, are scattered around under the action of the conical grain distributor 130, and enter the annular channel of the grain falling pipe 120 along the grain sliding plate at the lower part of the grain receiving hopper 110.
3. The grains fall into the bottom of the squat silo along the annular channel of the grain falling pipe 120 and flow into the squat silo from the lower end of the outer pipe 122; when the height of the grain in the tube is higher than that of the lower end of the outer tube 122 and reaches the grain outlet 122a of the first layer (the layer closest to the ground) on the outer tube 122, the grain naturally flows out along the grain outlet 122a, and when the grain level in the grain falling tube 120 is sequentially increased, the grain naturally flows out along the grain outlet 122a of the higher layer.

4. And when the grain surface reaches the grain loading height, closing the grain feeding equipment and the diagonal flow fan in sequence.
The high fall of silos such as a shallow round silo and the like during grain feeding is a main factor causing the increase of the breakage rate, the scattering performance of grains is the basis of automatic grading, and due to the fact that grain grains are different in shape, maturity, impurity types and the like, the components of a formed grain stack have different scattering performance, so that the components similar in properties tend to gather at the same position in the high-altitude scattering process of the grains, different gathering areas are formed in the grain stack, the components of the grain stack are redistributed, and cracks and breakage are caused by grain impact.
The utility model discloses top setting at the squat silo connects grain fill 110 and divides grain ware 130, can change grain flow direction to through setting up the air current that fan 140 produced, produce the effect of air supporting to grain, reduce the grain speed that falls, avoided moreover in grain granule and the current device with the multistage striking of chute or hopper etc. thereby reduced the broken increase that grain falling grain striking formed. Meanwhile, after the grain flow is dispersed by the grain distributor 130, the powder and impurity particles in the grain entering the silo are diffused to the position 3-5 meters away from the center of the squat silo by the airflow generated by the fan 140, so that the powder and impurity particles are prevented from being finally gathered at the center of the silo to form a powdery material column, and the automatic grading of the grain in the silo is reduced. Can improve the effects of ventilation, fumigation, circulation and the like of grains in the center in the later storage process.
