The nozzle 1 is arranged on the inner wall of the inclined hopper 15 and is positioned above the high-level photoelectric tube 9, and the air outlet of the nozzle 1 is aligned with the position where the light beam of the high-level photoelectric tube 9 passes through the window 10. The air outlet of the nozzle 1 is flat, and can eject radial air flow as shown in fig. 3. The direction of the air outlet of the nozzle 1 is adjusted to be aligned with the position of the light beam of the high material level photoelectric tube 9 passing through the window 10, so that blown air flow can blow down reconstituted tobacco adsorbed at the position, and the light beam is prevented from being shielded.

All install nozzle 1 on two relative inside walls of oblique hopper 15, every nozzle 1 is connected with a check valve 2, and every check valve 2 is connected with an elbow fitting 3 respectively, and it has the through-hole to open on the hopper 15 lateral wall to one side, and elbow fitting 3 passes the through-hole and is connected with gas pipeline 4, and two elbow fittings 3 are connected with a gas pipeline 4. The one-way valve 2 is shown in fig. 4 and the elbow fitting 3 is shown in fig. 5.

The gas pipeline 4 is connected with a gas source device 8, the gas source device 8 adopts an air compressor, and compressed air is adopted to remove the reconstituted tobacco adsorbed on the window 10. The gas pipeline 4 is sequentially provided with a ball valve 7, a filtering and reducing valve 6 and a three-way electromagnetic valve 5, and as shown in fig. 6, the three-way electromagnetic valve 5 is a two-position three-way electromagnetic valve.
