The back blowing cleaning can be carried out only when no wind pressure exists in the blast pipe. When the motor at the bottom of the discharging belt and the motor at the discharging harrow pin are in a shutdown state, no wind pressure exists in the blast pipe, and the blowback cleaning can be carried out at the moment.
