[0041] The rotating assembly includes a rotating plate 31, the middle part of which is rotatably connected to the rotating rod 6 through a torsion spring rod, a sliding groove 32 is provided at the bottom of the rotating plate 31, and a rotating shaft 33 that slides with the sliding groove 32 is fixedly connected to the top of the movable plate 10, and the bottom of the rotating plate 31 is pressed against the inner wall of the outer gear ring 23.

[0042] Fixed long needles 34 are movably inserted on both sides of the working plate 1, a walking wheel is provided at the bottom of the working plate 1, and a connecting hole 35 fixedly connected to the rotating sleeve 4 is opened at the bottom of the threaded rod 2. During the rotation of the threaded rod 2, garbage debris enters the rotating sleeve 4 through the connecting hole 35.

[0043] The overall idea of ​​this embodiment is: after the garbage briquetting is completed, the working plate 1 is moved so that the threaded rod 2 and the cutting blade 7 are located directly above the garbage briquetting, and the motor 24 is started. Under the action of the outer gear ring 23 that performs a circular motion, the movable plate 10 is moved downward, so that the matching blade 9 is moved out of the embedding groove 8. The matching blade 9 that is moved out of the embedding groove 8 automatically rotates and switches from a vertical state to a horizontal state, so that the matching blade 9 cuts in the horizontal direction and the cutting blade 7 cuts in the vertical direction. The area of ​​the threaded assembly of the threaded rod 2 is cut and segmented in advance to avoid squeezing and blocking the permeable channels around the briquetting during the threaded drilling of the threaded rod 2, to avoid the briquetting debris from being discharged in time during the drilling of the threaded rod 2, and to squeeze and block the permeable channels around the briquetting;

[0044] At the same time, the auger 5, the L-shaped plate 26, the outer tooth ring 23 and the cutting blade 7 (in an arc shape) always rotate clockwise, and under the action of the non-rotating inner tooth ring 21, the threaded rod 2 rotates counterclockwise, so that the auger 5 punches the channel in the middle of the threaded rod 2 to transport the cut briquette slag;

[0045] When the L-shaped plate 26 drives the outer toothed ring 23 to make a circular motion, the outer toothed ring 23 acts on the incomplete toothed ring 22, causing the gap of the incomplete toothed ring 22 to stop for a period of time, thereby causing the gap of the threaded rod 2 to stop for a period of time. During this period of stopping, the auger 5 always keeps rotating, thereby ensuring the transportation of the cut garbage debris, avoiding blockage caused by untimely cleaning speed, and also retaining a certain amount of time to facilitate the cutting blade 7 and the matching blade 9 to cut the inside of the pressing block.

[0046] The working principle of the cutting blade 7 making circular motion and the threaded rod 2 and the auger 5 making opposite motions is as follows: the motor 24 is started, driving the plug-in rod 25 to rotate, thereby driving the auger 5 to continuously rotate, the L-shaped plate 26 makes circular motion, the outer gear ring 23 rolls along the inner gear ring 21 (the inner gear ring 21 never rotates), the rolling outer gear ring 23 makes the incomplete gear ring 22 rotate, and the incomplete gear ring 22 rotates in gap (when the non-tooth position of the incomplete gear ring 22 cooperates with the outer gear ring 23), thereby making the threaded rod 2 and the rotating sleeve 4 rotate in gap;

[0047] The L-shaped plate 26 moves in a circular motion, while driving the rotating rod 6 and the movable plate 10 to move in a circular motion synchronously, thereby causing the cutting blade 7 to move in a circular motion

[0048] It is worth noting that the self-rotation direction of the threaded rod 2, the self-rotating sleeve 4 and the cutting blade 7 is opposite to the self-rotation direction of the auger 5, so that the auger 5 always conveys the crushed briquette and slag, which helps to improve the conveying efficiency.

[0049] The working principle of the movable plate 10 moving downward: when the L-shaped plate 26 drives the rotating rod 6 to rotate in a circle, when the rotating rod 6 rotates counterclockwise, the rotating rod 6 contacts the inner wall of the outer gear ring 23, thereby driving the outer gear ring 23 to roll, and the rotating plate 31 moves relative to the outer gear ring 23, so that the bottom of the rotating plate 31 is pressed by the inner wall of the outer gear ring 23, the bottom of the rotating plate 31 rotates downward, and the top rotates upward, and the downward rotating slide groove 32 acts on the rotating shaft 33, so that the movable plate 10 moves downward along the limit ring 27 and the cutting blade 7, wherein the baffle 16 and the opposite surface of the movable plate 10 are magnetically matched with each other, that is, the outer surface layers of the two are mutually matched magnetic layers.

[0050] The working principle of the matching blade plate 9 moving from the embedded groove 8 and rotating to a horizontal state: during the process of the movable plate 10 moving downward a certain distance, the clamping column 18 is driven to move downward, acting on the inclined block 19, so that the baffle plate 16 moves along the embedded groove 8, pushing the fixed block 12 and the matching blade plate 9 to move out of the embedded groove 8. When the fixed block 12 and the matching blade plate 9 are moved out, the movable plate 10 presses against the movable block 14, so that the movable block 14 and the slide bar 15 move vertically downward, and the vertically downward slide bar 15 (the limiting groove 17 on the baffle plate 16 also moves the slide bar 15 vertically downward) cooperates with the inclined sliding groove 13, so that the fixed block 12 and the matching blade plate 9 rotate, so that the matching blade plate 9 in the vertical state switches to a horizontal state, so that the matching blade plate 9 cuts in the horizontal direction, and the cutting blade plate 7 cuts in the vertical direction, and the area of ​​the threaded assembly of the threaded rod 2 is cut into segments in advance;

[0051] It is worth noting that when the cutting blade 7 rotates to cut, the pressure column 11 moves under the reaction of the inside of the garbage pressing block, which helps to cooperate with the blade 9 to move from the embedding groove 8;

[0052] Among them, the baffle 16 ensures that the garbage debris enters the embedding groove 8, and the fixed block 12 and the limiting groove 17 are always sealed and matched, and the sliding groove 13 and the baffle 16 are always sealed and matched to prevent the compressed block debris from entering.

[0053] The vertical plate 29 slides along the U-shaped plate 30, the structure between the threaded rod 2 and the limiting ring plate 28 (excluding the limiting ring 27) moves downward, the rotating rod 6 and the movable plate 10 are movable along the vertical direction of the limiting ring 27, and the limiting ring 27 rotates at the original position, and rotates with the rotating rod 6 and the movable plate 10;

[0054] In this solution, the inner gear ring 21 needs to be moved downward, which can be done manually or with the cooperation of other instruments (such as a pneumatic device) to ensure the advancement of the threaded rod 2.
