[0002] At present, the bulk transportation of grain production enterprises has become a trend, and the newly built or expanded grain plants will be equipped with corresponding bulk grain silos. Under the condition that the site and other conditions permit, many grain plants also increase the bulk grain storage facilities. On the one hand, bulk grain can reduce procurement costs; on the other hand, bulk grain can realize automation, especially the grain can directly enter the crushing and dosing sections of the workshop through the equipment, while if bagged grain is used, manual bag cutting and feeding are required, which results in high labor intensity and poor working environment. However, at present, a considerable part of grain production enterprises do not have bulk grain silos, and therefore they choose to store grain in the form of grain warehouse. That is, when feeding, the grain is shovelled by a forklift to the feeding port for feeding. At present, in the actual production of grain plants, this bulk storage form of grain will continue for a certain period of time.

Bulk grain directly flows out from the outlet of the scraper, and a large amount of dust will be generated due to impact during the falling process; 2. A discharge port is arranged at the discharge port, and the bulk material slides to the ground through the chute. This method can alleviate the dust caused by the impact of bulk grain to a certain extent, but the bulk material still has the phenomenon of dust overflow during the falling process, especially when the purchased batch of grain contains a lot of powder, the above two methods will cause the bulk grain to overflow during unloading, causing environmental pollution.
