[0018] The solid waste treatment device provided by this disclosure can achieve the following technical effects:
[0019] This disclosure provides a solid waste treatment device, including a support plate, a treatment box, a first crushing roller, a second crushing roller, a hydraulic cylinder, a moving plate, moving teeth, a transmission component, and a driving component. The support plate includes multiple screen holes on its top surface for discharging material and controlling the particle size. The treatment box is mounted on the top surface of the support plate and surrounds the multiple screen holes, used to contain the solid waste to be crushed. The first crushing roller is rotatably mounted on the treatment box along its length and located on both sides of the treatment box along its width, with both first crushing rollers capable of rotating relative to the treatment box. The crushing teeth of the two first crushing rollers mesh with each other for initial crushing of the solid waste. The second crushing roller is rotatably mounted on the treatment box in the opposite direction along its length and located below one of the two first crushing rollers along the height of the treatment box, capable of rotating relative to the treatment box. The hydraulic cylinder is mounted on the side wall of the treatment box along its width, with its moving end facing the second crushing roller, used to provide driving force to achieve linear movement. The movable plate is mounted on the moving end of the hydraulic cylinder, along the height direction of the processing box, below the other of the two first crushing rollers. Driven by the hydraulic cylinder, it moves closer to or further away from the second crushing roller. Movable teeth are evenly mounted on the movable plate along the length of the processing box, working in conjunction with the second crushing roller to perform secondary crushing of solid waste.

Under the drive of the hydraulic cylinder, multiple movable teeth mesh with the crushing teeth of the second crushing roller.
[0020] In operation, controlling the drive mechanism causes the second crushing roller to rotate. Then, under the transmission mechanism, the two second crushing rollers on both sides rotate in opposite directions. When the two second crushing rollers rotate in opposite directions, the solid waste is initially crushed using the shearing and tearing principle between the two relatively rotating crushing rollers, breaking it into small pieces. After the initially crushed solid waste falls under the influence of gravity, controlling the hydraulic cylinder causes the moving plate to move towards the second crushing roller, ultimately pushing the initially crushed solid waste and engaging multiple moving blades with the crushing teeth of the second crushing roller. At this point, the interaction between the multiple moving blades and the second crushing roller further shreds, shears, and compresses the initially crushed solid waste into smaller particles. The output particle size is controlled by the sieve holes, achieving staged crushing.

[0038] Combination Figures 1 to 5As shown, this embodiment of the present disclosure provides a solid waste treatment device, including a support plate 1, a treatment box 2, a first crushing roller 3, a second crushing roller 4, a hydraulic cylinder 5, a moving plate 6, moving teeth 7, a transmission component, and a driving component. The support plate 1 includes multiple screen holes on its top surface, which are used for material discharge and to control the discharge particle size. The treatment box 2 is installed on the top surface of the support plate 1 and surrounds the multiple screen holes for containing the crushed solid waste. The first crushing roller 3 is rotatably installed on the treatment box 2 along its length and located on both sides of the treatment box 2 along its width. Both first crushing rollers 3 can rotate relative to the treatment box 2. The crushing teeth of the two first crushing rollers 3 mesh with each other for initial crushing of the solid waste. The second crushing roller 4 is rotatably installed on the treatment box 2 in the opposite direction along its length and located below one of the two first crushing rollers 3 along the height of the treatment box 2, and can rotate relative to the treatment box 2. Hydraulic cylinder 5 is installed on the side wall of processing box 2 along the width direction of processing box 2, with the moving end of hydraulic cylinder 5 facing the second crushing roller 4, to provide driving force for linear movement. Moving plate 6 is installed on the moving end of hydraulic cylinder 5, along the height direction of processing box 2, below the other of the two first crushing rollers 3, and moves closer to or away from the second crushing roller 4 under the drive of hydraulic cylinder 5. Moving teeth 7 are evenly installed on moving plate 6 along the length direction of processing box 2, working in conjunction with the second crushing roller 4 to perform secondary crushing of solid waste. Transmission component is installed between the two first crushing rollers 3 and the second crushing roller 4 to transmit driving force, causing the two first crushing rollers 3 to rotate in opposite directions as the second crushing roller 4 rotates. Driving component is installed between support plate 1 and the second crushing roller 4 to provide driving force for rotating the second crushing roller 4. Under the drive of hydraulic cylinder 5, multiple moving teeth 7 mesh with the crushing teeth of the second crushing roller 4.
[0039] This embodiment of the solid waste treatment device controls the operation of the drive component to rotate the second crushing roller 4. Then, under the transmission of the transmission component, the two sides of the second crushing roller 4 rotate in opposite directions. When the two sides of the second crushing roller 4 rotate in opposite directions, the solid waste is initially crushed using the mutual shearing and tearing principle between the two relatively rotating crushing rollers, breaking the solid waste into small pieces. After the initially crushed solid waste falls under the action of gravity, the hydraulic cylinder 5 is activated, causing the moving plate 6 to move towards the second crushing roller 4, ultimately pushing the initially crushed solid waste to move and causing multiple moving blades to engage with the crushing teeth of the second crushing roller 4. At this time, the interaction between the multiple moving blades and the second crushing roller 4 allows the initially crushed solid waste to be shredded, sheared, and compressed to a smaller particle size. The discharge particle size is controlled by the screen holes, achieving step-by-step crushing.
[0040] Optionally, the transmission components include gears 8, a first sprocket 9, a second sprocket 10, and a chain 11. Gears 8 are respectively mounted on the main shafts of the two first crushing rollers 3, both located outside the processing box 2. The gears 8 mesh with each other to transmit driving force. The first sprocket 9 is mounted on the main shaft of either of the two first crushing rollers 3, located outside the processing box 2, and is used to drive the connected first crushing roller 3 to rotate. The second sprocket 10 is mounted on the main shaft of the second crushing roller 4, located outside the processing box 2, and rotates under the drive of the second crushing roller 4. The chain 11 is fitted onto the first sprocket 9 and the second sprocket 10 to transmit driving force.
[0041] In this embodiment, driven by an external force, the second crushing roller 4 rotates, which in turn drives the second sprocket 10 to rotate. The chain 11 then drives the first sprocket 9 to rotate, causing one of the two second crushing rollers 4 to rotate. Subsequently, through the meshing of the gears 8 on both sides, the other of the two second crushing rollers 4 rotates in the opposite direction, ultimately achieving the function of the first crushing roller 3 rotating in the opposite direction as the second crushing roller 4 rotates.
[0042] Optionally, the drive components include a reducer 12 and a motor 13. The reducer 12 is mounted on the top surface of the support plate 1 and located outside the processing box 2, and the output end of the reducer 12 is connected to the main shaft of the second crushing roller 4. The motor 13 is mounted on the input end of the reducer 12.
[0043] In this embodiment, the control motor 13 operates, which, through the reducer 12, drives the first crushing roller 3 to rotate, ultimately causing the two second crushing rollers 4 to rotate in opposite directions. The reducer 12 serves to reduce the rotational speed and increase the output torque of the motor 13.
[0044] Optionally, the system also includes linear bearings 14 and guide shafts 15. The linear bearings 14 are mounted on the side wall of the processing chamber 2 along its width and are located on both sides of the processing chamber 2 along its length. The guide shafts 15 pass through the linear bearings 14 on both sides and are connected to the moving plate 6.
[0045] In this embodiment, the linear bearings 14 on both sides and the guide shafts 15 on both sides together serve as guides and supports to improve the stability of the moving plate 6 when it moves and reduce the radial force on the moving end of the hydraulic cylinder 5.
[0046] Optionally, it also includes first fixed teeth 16. The first fixed teeth 16 are evenly installed on the inner wall of the processing box 2 along the length direction of the processing box 2, and located on both sides of the processing box 2 along the width direction of the processing box 2. The multiple first fixed teeth 16 on both sides respectively mesh with the crushing teeth of the first crushing rollers 3 on both sides.
[0047] In this embodiment, the multiple first fixed teeth 16 on both sides are also used to perform initial crushing of solid waste, improve the initial crushing effect, and prevent the solid waste from falling directly between the first crushing rollers 3 on both sides and the inner wall of the box.
[0048] Optionally, it also includes a second fixed tooth 17. The second fixed teeth 17 are evenly installed on the inner wall of the processing box 2 along the length direction of the processing box 2, and multiple second fixed teeth 17 mesh with the crushing teeth of the second crushing roller 4.
[0049] In this embodiment of the present disclosure, a plurality of second fixed teeth 17 are also used to further crush the solid waste, thereby improving the effect of further crushing.
[0050] Optionally, a stop block 18 is also included. The stop block 18 is installed on the inner wall of the processing box 2, along the height direction of the processing box 2, and located above the moving plate 6.
[0051] In this embodiment, the baffle 18 acts as a barrier to prevent the initially crushed solid waste from falling directly between the moving plate 6 and the side wall of the processing box 2. It also prevents the solid waste from moving upwards during the compression process, thus improving the pressure effect on the solid waste.
[0052] Optionally, it also includes a first seated bearing 19. The first seated bearing 19 is respectively mounted on both ends of the main shaft of the first crushing roller 3 and the second crushing roller 4 on both sides, and is installed on the side wall of the processing box 2.
[0053] In this embodiment, the first bearing 19 is used to reduce the friction between the first crushing rollers 3 and the second crushing rollers 4 on both sides and the processing box 2, and to improve the accuracy of the first crushing rollers 3 and the second crushing rollers 4 on both sides when rotating relative to the processing box 2.
[0054] Optionally, it also includes a second seated bearing 20. The second seated bearing 20 is respectively mounted on both ends of the main shaft of the second crushing roller 4, and is installed on the top surface of the support plate 1.
[0055] In this embodiment, the second bearing 20 is used to improve the stability of the second crushing roller 4 during rotation and to improve the rotational accuracy of the second crushing roller 4.
[0056] Optionally, it also includes support legs 21. The support legs 21 are respectively installed at the four corners of the top surface of the support plate 1.
[0057] In this embodiment, the four corner support legs 21 are used to abut against the ground, thereby supporting the entire device. Simultaneously, multiple screen holes are detached from the ground, allowing the receiving or conveying device to be positioned below them.
