The bottom wall of the inner cavity of the cleaning box 60 slides The trapezoidal push block 65 is dynamically connected. The trapezoidal push block 65 is trapezoidal, and its inclined surface is on the upper side, inclined to the left, and the length of the trapezoidal push block 65 is long enough to catch the material leaking out of the leakage port when moving. A baffle plate 650 is fixed on the upper inclined surface of the trapezoidal push block 65. When the trapezoidal push block 65 moves to the left side wall of the cleaning box 60, the baffle plate 650 is still on the right side of the leakage port on the arc surface of the U-shaped arc plate 30, so that the material at the leakage port always falls on the upper inclined surface of the trapezoidal push block 65. The baffle plate 650 is threadedly connected to the No. 1 screw 610. The No. 1 screw 610 rotates to move the baffle plate 650 and the trapezoidal push block 65.

[0054] Next, two symmetrical matching blocks 671 are fixed to the left end of the cleaning box 60, and the lower ends of the two matching blocks 671 are provided with sliding rods 670, which penetrate the matching blocks 671 on the same side and are slidably connected with the matching blocks 671. A blocking plate 67 is fixed to the lower ends of the two sliding rods 670, and a rack 2 66 meshing with the third gear 611 is fixed to the middle part of the upper end of the blocking plate 67. The blocking plate 67 is slidably connected to the left end of the cleaning box 60, and a cleaning port is opened at the left end of the cleaning box 60, and the blocking plate 67 is in close contact with the cleaning port. When the third gear 611 does not rotate, the blocking plate 67 blocks the cleaning port, so that the material gathers in the inner cavity of the cleaning box 60.

[0055] Specific implementation of this embodiment: After the device has been running for a period of time, because the U-shaped arc plate 30 is U-shaped, the materials will slide from the inner surface of the U-shaped arc plate 30 to the lowest point of the concave part of the U-shaped arc plate 30 and accumulate around the leakage port. At this time, the motor 2 61 is turned on. With the start of the motor 2 61, the two reciprocating screws 3 64 rotate with the motor 2 61, and the screw 1 610 and the gear 3 611 also rotate with the motor 2 61;

[0056] like Fig.12 and Fig.13As shown, during the rotation of the two reciprocating screws 3 64, the push columns 640 on the outer surfaces of the two reciprocating screws 3 64 slide back and forth on the side wall of the cleaning box 60. When the two push columns 640 move to the left, the two reciprocating screws 3 64 contact the two support rods 622 respectively, and push the two support rods 622 to the left. The connecting columns 623 on the two support rods 622 slide in the inner cavity of the arc groove 620 on the same side, so that the arc plate 63 fixed to the upper ends of the two support rods 622 slides close to the arc outer surface of the U-shaped arc plate 30, so that the arc plate 63 opens the leakage port on the arc surface of the U-shaped arc plate 30, so that the materials accumulated in the concave part of the U-shaped arc plate 30 fall from the leakage port into the inclined surface of the trapezoidal push block 65 in the inner cavity of the cleaning box 60;

[0057] Next, when the No. 1 screw rod 610 rotates, the baffle plate 650 and the trapezoidal push block 65 move to the left on the bottom wall of the inner cavity of the cleaning box 60. During the movement of the trapezoidal push block 65 to the left, the No. 3 gear 611 rotates to move the meshing rack 2 66 upward, so that the blocking plate 67 moves upward, the cleaning port is opened, and the trapezoidal push block 65 can push the material out of the inner cavity of the cleaning box 60. When the trapezoidal push block 65 moves to the left side wall of the cleaning box 60, the baffle plate 650 is still on the right side of the leakage port, so that the material leaking out of the leakage port of the U-shaped arc plate 30 can continue to fall on the inclined surface of the trapezoidal push block 65, so that the arc plate 63 can still be cleaned during the swinging, and will not accumulate in the inner cavity of the cleaning box 60.

[0058] When the materials in the concave part of the U-shaped arc plate 30 are basically cleaned, the motor 2 61 is reversed to make the blocking plate 67 fall to block the cleaning port, the trapezoidal push block 65 and the material blocking plate 650 are restored, and the two support rods 622 are also reset with the movement of the push column 640. The two connecting springs 621 are respectively connected to the two connecting columns 623 to reset the two support rods 622.

[0059] It should be noted that the drive motor 11, transmission roller 12, crawler 13, motor 1 21, missing gear 35, feed hopper 4, filter hopper 5 and motor 2 61 in the present invention are all prior arts, and their installation methods and control methods are also conventional designs, which will not be elaborated in detail in the present invention.
