[0025] Two symmetrical electric push rods 16 are fixedly connected to the inner wall of the bottom end of the discharge box 3. The telescopic ends of the two electric push rods 16 penetrate the inner wall of the bottom end of the discharge box 3 and are fixedly connected to a moving plate 17. The lower surface of the moving plate 17 is fixedly connected to a plurality of evenly distributed conical punching rods 18. The outer wall of the mounting frame is provided with a control panel 19. The first driving member 8, the second driving member 12, the electric push rod 16 and the alarm light 14 are all electrically connected to the control panel 19.
