[0005] Furthermore, the knife set includes a knife seat arranged on the top of the rotating shaft, and the knife seat is provided with multiple blades.

[0006] A lifting channel is provided between the lifting frame and the material receiving box, through which the rotating shaft can pass freely.

[0007] The switch valve is opened and closed by connecting to an electric push rod or a hydraulic cylinder.

[0008] The driven wheel sleeved on the outer wall of the rotating shaft is a driven gear or a driven pulley, and the corresponding motor is connected to the driving gear or the driving pulley to drive the rotating shaft to rotate.

[0013] When the utility model is in use, the elevator is started, and the lifting rod moves upward continuously, driving the turntable to move upward. During this process, the turntable and the rotating shaft move upward continuously, but the motor does not work. When the knife group approaches the switch valve, the switch valve opens, and the knife group continues to move upward to near the bottom of the silo, the motor drives the gear or pulley to make the rotating shaft rotate continuously, driving the knife group to push the material to open the material outlet, so that it is discharged smoothly from the discharge port, completing the cleaning of the material blockage at the material outlet.

[0014] The beneficial effects of the present invention are as follows: through the above technical solution, when in use, the knife group is driven by the elevator to clear the blockage at the silo outlet and stabilize the material. Most of the material after clearing the blockage enters the next process through the discharge port. A small amount of bulk material in the clearing process is received by the maintenance box. The elevator drives the rotating knife group to clear the blockage at the silo outlet many times. By pushing open the material at the silo outlet, the clearing effect is obvious, ensuring the unobstructed flow of the discharge box outlet and ensuring the smooth progress of the entire production.
