Preferably, the discharge flow is adjustable by adjusting the flow rate and pressure of the air jets, and if the discharge is reached, the flow rate and pressure of the air jets are adjusted so that the material passes from the air jets to the conveying surface 41 again.
Further, the air injection mechanism comprises an air injection piece 31 and an air injection pipe group, the air injection piece 31 is positioned above the conveying surface 41, a plurality of air injection holes are distributed on the surface of the air injection piece 31, the air injection pipe group comprises a plurality of pipelines, and each pipeline is communicated with different air injection holes; the jet pipe group is connected with an adjustable air supply mechanism, and the adjustable air supply mechanism is used for supplying air to the jet piece 31 through the jet pipe group and adjusting the flow rate and pressure of air flow jetted by the jet holes.

Specifically, the discharge amount is adjusted by adjusting the number of the opened electromagnetic valves 33, and the smaller the opened electromagnetic valves 33 are, the smaller the discharge amount is; the more the solenoid valves 33 are opened, the more the discharge amount is, and when the solenoid valves 33 are fully opened, the material on the conveying surface 41 is completely discharged.
In the process of realizing selective unloading, only the materials in a certain size range can be sprayed by controlling the flow and the pressure of the airflow of the air injection holes; the material with the size larger than the size is not sprayed or is sprayed to a lower height due to larger gravity, and then the material is fed on the conveying surface 41 again; material smaller than this size fraction is blown further and cannot fall into the area where the material is collected, again onto the conveying surface 41 for feeding.
