A longitudinal sliding plate 607 is slidably installed inside the longitudinal groove 605. A pull rod 608 is installed at the bottom end of the longitudinal sliding plate 607. The pull rod 608 extends into the first through groove 601. A connecting rod 609 is provided between the pull rod 608 and the filter plate 602. Rotary seats 610 are symmetrically mounted on both ends of 609. The two rotating seats 610 are fixedly mounted on the bottom end of the pull rod 608 and the top wall of the filter plate 602, respectively. A first spring 611 is installed on the top of the longitudinal slide plate 607. The top of the first spring 611 is fixedly connected to the inner top wall of the longitudinal slide groove 605. When the pull rod 608 moves upward, it pulls the filter plate 602 to rotate to a horizontal state. A side groove 606 is opened on the side of the longitudinal slide groove 605 away from the inner cavity of the treatment box 1. The side groove 606 extends to the outside of the treatment box 1. A connecting horizontal plate 612 is installed on the outer wall of the treatment box 1 near the first through groove 601. The two ends of the connecting horizontal plate 612 are slidably connected to the two side grooves 606, respectively. The two ends of the two connecting horizontal plates 612 are fixedly connected to the two longitudinal slide plates 607, respectively.

[0035] The crushing assembly 5 includes crushing rollers 501 symmetrically arranged inside the processing box 1, forming a crushing gap between the two crushing rollers 501. The crushing gap is located below the feed hopper 2. Rotating shafts 502 are symmetrically installed at both ends of the crushing rollers 501. The rotating shafts 502 are rotatably connected to the processing box 1. The rotating shaft 502 of one of the crushing rollers 501 is fixedly connected to the output shaft of the first motor 503. The first motor 503 is fixedly installed on the front of the processing box 1. Gears 504 are coaxially installed on the other rotating shaft 502 of both crushing rollers 501. The two gears 504 mesh with each other.

[0036] The reflux drive assembly 7 includes a reflux box 701 located on the side of the processing box 1 near the first through slot 601. A movable frame 702 is mounted on one side of the reflux box 701. A sliding block 703 is fixedly mounted on the bottom end of the movable frame 702. The sliding block 703 is slidably mounted inside a sliding groove, which is located on the back of the processing box 1. A first screw 704 is rotatably mounted inside the sliding groove. The first screw 704 is threadedly connected to the sliding block 703. The top end of the first screw 704 is fixedly connected to the output shaft of a second motor 705. The second motor 705 is fixedly mounted on the top end of the processing box 1. A second through slot 706 is provided on the side of the reflux box 701 near the processing box 1. An auxiliary receiving unit 709 is installed inside the reflux box 701. A reflux discharge unit 710 is installed at the bottom end of the reflux box 701. The filter plate 602 is located near the reflux box 701. One end is tilted downwards, allowing incompletely crushed slag falling onto the top of the filter plate 602 to slide down into the return box 701. When the return box 701 stores a significant amount of incompletely crushed slag, the second motor 705 drives the return box 701 upwards, facilitating the return of the incompletely crushed slag for further crushing and improving the crushing effect. When the return box 701 is in the receiving state, the pressure rod 707 presses the pull rod 608 to its downward limit position, causing the filter plate 602 to tilt, facilitating the collection of incompletely crushed slag. When the return box 701 moves upwards, the pull rod 608 moves upwards under the elastic force of the first spring 611, pulling the filter plate 602 upwards to a horizontal position, preventing subsequent incompletely crushed slag from falling onto the filter plate 602 and being directly discharged after the return box 701 leaves, thus improving the crushing effect.

[0037] The auxiliary receiving unit 709 includes a receiving plate 7093 disposed inside the return box 701. The end of the receiving plate 7093 near the processing box 1 moves outward from the second through groove 706. The end of the receiving plate 7093 near the processing box 1 is inclined upward. Horizontal sliders 7092 are symmetrically installed at both ends of the receiving plate 7093. The horizontal sliders 7092 are slidably installed inside the horizontal slide groove 7091. The horizontal slide groove 7091 is symmetrically opened on the inner walls of both sides of the return box 701. A second spring 7094 is fixedly installed on the side of the horizontal slider 7092 away from the processing box 1. One end of the second spring 7094 is fixedly connected to the end of the horizontal slide groove 7091 away from the processing box 1. A magnet 7095 is installed on the side of the horizontal slider 7092 away from the processing box 1. An electromagnet 7096 is fixedly installed on the inner wall of the end of the horizontal slide groove 7091 away from the processing box 1.

[0038] The reflux discharge unit 710 includes a discharge pipe 7101 fixedly installed at the bottom of the reflux box 701. The discharge pipe 7101 is connected to the inner cavity of the reflux box 701. A movable plate 7103 is provided on the side of the discharge pipe 7101 away from the processing box 1. The length of the movable plate 7103 is greater than the length of the discharge pipe 7101. Fixed plates 7102 are symmetrically installed at both ends of the discharge pipe 7101. A third spring 7104 is installed between the movable plate 7103 and the fixed plate 7102. A slot 7106 is opened on the side of the discharge pipe 7101 away from the processing box 1. A baffle 7105 is fixedly installed on the side of the movable plate 7103 close to the discharge pipe 7101. The baffle 7105 passes through the slot 7106 and enters the interior of the discharge pipe 7101, and the baffle 7105 cuts off the discharge pipe 7101.

[0039] A pressure rod 707 is symmetrically installed at the top of the return box 701. The pressure rod 707 is set in an inverted L-shape. A second contact 708 is fixedly installed on the upper top wall of the pressure rod 707. The two second contacts 708 correspond to the two first contacts 613 respectively. A battery is connected in series between the two second contacts 708. The two second contacts 708 are connected in series with two electromagnets 7096. When the return box 701 is in the receiving state, the second contacts 708 contact the first contacts 613, so that the electromagnets 7096 generate a repulsive force on the magnetic block 7095, causing the receiving plate 7093 to move towards the processing box 1 to below the end of the filter plate 602. Since the receiving plate 7093 and the filter plate 602 are both in an inclined state, it ensures that the incompletely crushed slag slides smoothly into the return box 701, improving the crushing effect.

[0040] The top receiving assembly 8 includes side blocks 801 symmetrically installed on both sides of the feeding hopper 2. A guide groove 802 is provided on each side block 801, and a guide rod 803 is movably installed inside the guide groove 802. A receiving plate 804 is provided above the feeding hopper 2, and the receiving plate 804 is fixedly connected to one end of the guide rod 803. The end of the receiving plate 804 near the return box 701 is inclined upwards. Top rods 805 are symmetrically installed on the top of the end of the receiving plate 804 near the return box 701. The receiving plate 804 partially obscures the top of the feeding hopper 2. An end plate 806 is fixedly installed on the other end of the guide rod 803, and a bottom plate 807 is installed on the bottom end of the end plate 806. A sliding box 808 is fixedly installed on the top of the processing box 1, and the bottom plate 807 is slidably installed inside the sliding box 808. The second screw 809 is rotatably installed inside the 08. The second screw 809 is threadedly connected to the base plate 807. One end of the second screw 809 is fixedly connected to the output end of the third motor 810. The third motor 810 is fixedly installed on the sliding box 808. The top of the feed bin 2 is provided with an inclined receiving plate 804. The receiving plate 804 partially covers the feed bin 2 without affecting the feeding. When the return box 701 moves upward, the receiving plate 804 moves towards the return box 701 to below the discharge pipe 7101, so that the slag that is not completely crushed in the return box 701 can slide along the receiving plate 804 into the feed bin 2 for return feeding, thereby improving the crushing effect. At the same time, the movement of the receiving plate 804 pushes the baffle 7105 outward through the top rod 805 to open the discharge pipe 7101, so that the slag that is not completely crushed can be discharged.

[0041] Working principle: In the original state, the pressure rod 707 on the return box 701 pulls the connecting horizontal plate 612 downward, so that the second contact 708 contacts the first contact 613. At this time, the filter plate 602 is pressed to an inclined state, and the second contact 708 contacts the first contact 613, so that the electromagnet 7096 is energized and generates a repulsive force on the magnetic block 7095. Under the action of the repulsive force, the receiving plate 7093 moves towards the processing box 1, so that the receiving plate 7093 enters the first through groove 601 and moves to the bottom of the filter plate 602. Since both the filter plate 602 and the receiving plate 7093 are in an inclined state, it is convenient for the incompletely crushed slag to enter the return box 701.

[0042] The slag is fed into the processing box 1 through the feed hopper 2, so that the slag passes between the two crushing rollers 501. When passing between the two crushing rollers 501, the slag is crushed and falls onto the filter plate 602. The slag that is completely crushed falls into the collection box 4 through the filter hole 604, while the slag that is not completely crushed falls into the return box 701 along the filter plate 602, which is convenient for use.

[0043] When a large amount of incompletely crushed slag is stored in the return box 701, the second motor 705 is turned on, causing the first screw 704 to rotate and drive the return box 701 to move upward until the bottom end of the discharge pipe 7101 moves above the receiving plate 804. When the return box 701 moves upward, the pull rod 608 moves upward under the elastic force of the first spring 611, thereby pulling the filter plate 602 to rotate upward to a horizontal state. This facilitates the direct discharge of incompletely crushed slag from the filter plate 602 during subsequent crushing, ensuring the crushing effect of the slag. When the filter plate 602 is in a horizontal state, the return box 701 continues to move upward, causing the electromagnet 7096 to be de-energized. At this time, the receiving plate 7093 enters the return box 701 under the elastic force of the second spring 7094 and leaves the bottom of the filter plate 602, facilitating the smooth upward movement of the return box 701.

[0044] After the return box 701 moves to its highest position, the third motor 810 is turned on, causing the second screw 809 to rotate, thereby driving the receiving plate 804 towards the discharge pipe 7101. When the receiving plate 804 moves to the bottom of the discharge pipe 7101, the push rod 805 pushes the movable plate 7103 to move away from the feed bin 2, thereby opening the discharge pipe 7101. This allows the stored slag that has not been completely crushed to fill the discharge pipe 7101 and fall onto the receiving plate 804, and then enter the feed bin 2 along the receiving plate 804. This facilitates the return crushing of the slag that has not been completely crushed, thereby improving the crushing effect.

[0045] After the slag is discharged, the third motor 810 controls the receiving plate 804 to move back, and the second motor 705 controls the return box 701 to move back to continue crushing.
