At present, the raw material bulk of feed production enterprises has become a trend. Newly built or expanded feed factories can be matched with corresponding bulk silos of raw materials, and storage facilities of the bulk raw materials are increased under the condition of permission of sites and other conditions of a few old feed factories. On one hand, the raw materials are in a bulk form, so that the purchase cost can be reduced; on the other hand, bulk raw materials are easy to realize automation, particularly, the bulk raw materials can be directly fed into the workshop sections of crushing, batching and the like through equipment, and if bagged raw materials are adopted, the processes of bag cutting, feeding and the like are needed manually, so that the labor intensity of personnel is high, the operation environment is poor and the like. However, there are currently a considerable number of feed manufacturers who, without having a bulk silo for the raw materials, have to resort to storing the raw materials in a ground-pushing manner in a raw material warehouse, i.e. when feeding, the raw materials are shoveled by a forklift into a feeding opening for feeding. At present, in the actual production of a feed mill, this bulk storage form of the material will also last for a certain time.

For the raw materials of feed production enterprises, a ground pile form is adopted, wherein after the bulk raw materials are conveyed to a storage point through a scraper, two discharging modes exist at present: 1. the bulk material flows out directly from the outlet of the scraper conveyor, and during the falling process (especially after the falling to the ground begins), large dust can be generated due to impact; 2. the chute is arranged at the discharge port of the scraper conveyor, bulk materials slide to the ground through the chute, and the mode relieves the flying dust caused by the impact of the bulk materials to a certain extent, but the phenomenon that the flying dust overflows in the falling process of the materials still exists, especially when the raw materials of purchased batches contain more powder.
