The discharge tube is connected to the suction hopper, and transfers inhaled depositions to the outside. The crushing screw is installed inside the suction hopper, and crushes the depositions. The second motor drives the crushing screw. The hydraulic pressure generating unit uses fluid pressure to operate the first motor and the second motor, and is configured to be remotely controllable. |
