After the box body is transported to a destination, an inflation pipeline (4) is connected with the air outlet end of an air compressor (19) through a first intermediate pipeline (18), an air bag inflation pipeline (9a) is connected with the air outlet end of the air compressor (19) through a second intermediate pipeline (20), a top cover (21) is opened, a discharge pipeline (13) is filled from a material port (6), the upper end of the discharge pipeline (13) is connected with a material inlet of a powder flowmeter (16) through a first discharge hose (15), a second discharge hose (17) is connected to a material outlet of the powder flowmeter (16), the air compressor is started, the lower end of the discharge pipeline falls onto the top surface of the powder material, a first valve (5a) is opened, compressed gas enters an inflation cabin (1b) at the lower part of the box body through the inflation pipeline (4), and is sprayed to the material cabin (1a) through a vent hole in a ventilation layer, so that the powder material (12) in the material cabin rolls under the action of negative, finally, the powder material is sent out from the lower opening of the discharging pipeline under the action of negative pressure, the powder flowmeter (16) monitors the flow of the powder material in real time and transmits a flow signal to the controller, when the flow of the powder material is higher than a preset low flow set value, the controller sends a signal, a third valve (5c) on the air bag discharging pipeline is closed, a second valve (5b) on the air bag inflating pipeline (9a) is opened, the annular air bag is inflated and extends towards the direction of the discharging pipeline until the annular air bag is tightly pressed on the discharging pipeline under the action of pressure, the height position of the discharging pipeline is kept still, the discharging state is kept, when the powder flowmeter monitors that the flow of the powder material is lower than the preset low flow set value, the third valve (5c) on the air bag discharging pipeline is opened, the pressure in the annular air bag is released, enough pressure cannot be kept, and the discharging pipeline is under the, the powder material discharging device slides downwards along the material port (6), so that the material inlet of the powder material discharging device is close to the surface of the powder material (12), and when the powder flowmeter monitors that the flow of the powder material is higher than a preset high-flow set value, a third valve (5c) on the air bag air discharging pipeline is closed again, so that the annular air bag is inflated to press the discharging pipeline, and high-flow discharging is kept.
