Description

Technical Field

[0001] This utility model relates to the field of crushing device technology, and in particular to a solid waste crushing device. Background Technology

[0002] A crushing device is a piece of equipment that uses mechanical force to crush and reduce the volume of solid materials. It uses crushing rollers to squeeze, shear, or impact the input solid waste, breaking it into smaller particles.

[0003] Existing technologies, such as the utility model patent with publication number CN204724225U, disclose a crushing device. This patent employs an open box body and a belt conveyor mechanism disposed on one side of the open box body and conveying material into the open box body. The bottom of the open box body has an outlet. Two opposing rotating rollers are rotatably mounted inside the open box body. Multiple arc-shaped mounting seats are fixedly connected along the axial direction on the outer circumference of the two rollers. A toothed crushing blade array and a columnar crushing blade array with a circular arc top are fixedly mounted on two adjacent arc-shaped mounting seats on the same roller body. This solves the problem that during operation, the toothed crushing blade array is used to crush agglomerated raw materials, and the columnar crushing blades with a circular arc top are used to grind the crushed powdery material, making it finer, thereby improving work efficiency and the fineness of the raw material. The arc-shaped mounting seats are used for modular installation of the crushing blades, allowing for convenient installation and disassembly.

[0004] The inventors discovered the following problems in the use of the crushing device during daily work: when the crushing roller comes into contact with the material, especially the material with a smooth or hard surface, it is easy to "bounce away" or "slip" from the gap between the crushing rollers due to uneven force, and it cannot be effectively gripped and crushed. This not only leads to incomplete crushing and requires repeated operation, reducing processing efficiency, but may also cause overload damage to the crushing roller and drive device due to material jamming. Utility Model Content

[0005] The purpose of this invention is to solve the problem of low crushing efficiency caused by material slippage on the crushing roller in the prior art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a solid waste crushing device, comprising a base, a crushing box fixedly connected to the upper surface of the base, two crushing rollers installed on the inner wall of the crushing box, a feeding frame fixedly connected to the lower surface of the crushing box, a driving device fixedly connected to one side of the crushing box, the output end of the driving device fixedly connected to the crushing rollers, an adjustment structure provided on the upper surface of the crushing box, the adjustment structure comprising two slide rails, the two slide rails fixedly connected to the crushing box, sliders slidably connected to the surfaces of the two slide rails, a support frame fixedly connected to the side of the two sliders close to each other, and a cylinder rotatably connected to the inner wall of the support frame. A support rod is threaded onto the inner wall of the cylinder. A pressure plate is fixedly connected to the lower end of the support rod. Two round rods are fixedly connected to the upper surface of the pressure plate. The arc surfaces of the two round rods are slidably connected to the support frame. A first bevel gear is fixedly connected to the outer arc surface of the cylinder. A second bevel gear meshes with the tooth surface of the first bevel gear. A servo motor is fixedly connected to the upper surface of the support frame. The output end of the servo motor is fixedly connected to the second bevel gear. A positioning rod is slidably connected to the upper surface of one of the sliders. A spring is sleeved on the arc surface of the positioning rod. The two ends of the spring are fixedly connected to the positioning rod and the slider, respectively. Several positioning holes are opened on the upper surface of one of the slide rails corresponding to the position of the positioning rod.

[0007] The effect achieved by the above components is that they can flexibly and accurately move and fix the pressure plate according to the specific position of the material to be crushed. By pressing down the solid waste with the pressure plate, it can effectively prevent the waste from slipping and splashing with the crushing roller during the crushing process, thus significantly improving the efficiency and thoroughness of crushing.

[0008] Preferably, both sides of the inner wall of the support frame are fixedly connected to a fixing plate, and the cross-section of the fixing plate is triangular.

[0009] The effect achieved by the above components is that the triangular structure of the fixing plate greatly enhances the overall rigidity and stability of the support frame, effectively resists the bending moment and vibration generated when the pressure plate is pressed down, prevents the support frame from deforming, and ensures the long-term stability and safety of the crushing operation.

[0010] Preferably, a pull ring is fixedly connected to the upper end of the positioning rod, and the pull ring is specifically a stainless steel ring.

[0011] The effects achieved by the above components are as follows: the stainless steel pull ring provides the operator with a labor-saving and convenient point of force application, making it easier to lift the positioning rod and move the slider. At the same time, the stainless steel material also ensures the durability of the pull ring under harsh working conditions.

[0012] Preferably, a bellows is fitted onto the arc surface of the positioning rod at the position corresponding to the spring, and the two ends of the bellows are fixedly connected to the slider and the positioning rod, respectively.

[0013] The effect achieved by the above components is that the added bellows forms a sealed protective cover, isolating the spring from the external environment, effectively preventing dust and debris from entering the spring, avoiding spring failure due to blockage or corrosion, thereby ensuring the reliability and service life of the positioning mechanism.

[0014] Preferably, the upper surface of the crushing box is provided with an auxiliary structure, the auxiliary structure including a bottom frame, the bottom frame being fixedly connected to the crushing box, a screw being rotatably connected to the surface of the bottom frame, a top frame being threadedly connected to the arc surface of the screw, the inner wall of the top frame being slidably connected to the bottom frame, and a plurality of auxiliary rods being fixedly connected to the surface of the bottom frame, the arc surfaces of the plurality of auxiliary rods being slidably connected to the top frame.

[0015] The aforementioned components achieve the following effect: the operator can easily adjust the height of the inlet barrier of the crushing chamber. When handling materials prone to splashing, the barrier can be raised to provide effective protection and ensure operational safety; when feeding large pieces of material, the barrier can be lowered to facilitate feeding. This flexible design allows the equipment to better adapt to different crushing needs and working scenarios.

[0016] Preferably, a disc is fixedly connected to the upper end of the screw, and a plurality of circular holes are opened on the arc surface of the disc, with a handle slidably connected to the inner wall of one of the circular holes.

[0017] The aforementioned components achieve the following effect: the combination of the disc and the handle forms a force-saving lever mechanism, making it easy and effortless to turn the screw and adjust the height of the enclosure. The detachable design of the handle also facilitates storage, avoids taking up extra space, and keeps the work area tidy.

[0018] Preferably, one of the auxiliary rods has a scale on its surface.

[0019] The effect achieved by the above components is that the scale provides an intuitive and accurate visual reference for adjusting the height of the fence, enabling the operator to quickly and accurately adjust the fence to the required height.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] In this invention, by setting an adjustment structure, the pressure plate can be flexibly and precisely controlled in both horizontal and vertical directions. This structure allows the pressure plate to move quickly and lock directly above the material to be crushed, and then be driven by a servo motor to press down stably, thereby effectively fixing the solid waste during the crushing process. This completely solves the problems of material slippage, jamming, or splashing between the material and the crushing roller, significantly improving crushing efficiency and uniformity. After the work is completed, the pressure plate can be smoothly lifted and moved back to its original position, making operation convenient and greatly enhancing the adaptability to different working conditions and the ease of use of the equipment.

[0022] By setting up an auxiliary structure, the overall height of the enclosure can be changed with a simple rotation operation. This effectively prevents the splashing of fragments during the crushing process, ensuring operational safety and environmental hygiene. It also allows the enclosure to be lowered to avoid interference when large materials are being placed, achieving a balance between safety protection and ease of operation, and greatly enhancing the practicality and applicability of the equipment.

The output end of the servo motor 610 is fixedly connected to the second bevel gear 609. A positioning rod 612 is slidably connected to the upper surface of one of the sliders 602. A spring 613 is sleeved on the arc surface of the positioning rod 612. The two ends of the spring 613 are fixedly connected to the positioning rod 612 and the slider 602, respectively. Several positioning holes 614 are opened on the upper surface of one of the slide rails 601 corresponding to the position of the positioning rod 612. The pressure plate 606 can be moved and fixed flexibly and accurately according to the specific position of the object to be crushed. The pressure plate 606 presses down on the solid waste, effectively preventing it from slipping and splashing against the crushing roller 3 during the crushing process, significantly improving the efficiency and thoroughness of crushing. Fixed plates 611 are fixedly connected to both sides of the inner wall of the support frame 603. The cross-section of the fixed plates 611 is triangular.

[0033] Detailed Instructions for Use: By setting the adjustment structure 6, first move the positioning rod 612 upwards. The positioning rod 612 moves upwards along the slider 602, disengaging from the positioning hole 614 on the slide rail 601. The spring 613 is in a stretched state, releasing the limit on the slider 602. At this time, the two sliders 602 and the support frame 603 can move along the two slide rails 601. Move the support frame 603 from one end of the slide rail 601 to above the solid waste to be crushed. Then release the positioning rod 612. Under the action of the spring force of the spring 613, the positioning rod 612 moves towards the slider 602. The positioning rod 612 moves downwards. In the corresponding positioning hole 614, the positions of slider 602 and support frame 603 are fixed. Then, servo motor 610 is started. The output end of servo motor 610 drives the second bevel gear 609 to rotate. The second bevel gear 609 drives the first bevel gear 608 and cylinder 604 to rotate through the tooth block. As cylinder 604 rotates along support frame 603, it drives support rod 605 to move downward through the thread. Support rod 605 drives pressure plate 606 to move downward and press the solid waste. The two round rods 607 on pressure plate 606 always slide along support frame 603. The solid waste is subjected to the action of pressure plate 606. The lower part no longer slips against the crushing roller 3. After the solid waste is crushed, the servo motor 610 is controlled to rotate in the opposite direction. At this time, the cylinder 604 rotates in the opposite direction, and the support rod 605 and the pressure plate 606 move upward and reset as a whole. When the pressure plate 606 is no longer needed, the positioning rod 612 can be operated to release the limit of the slider 602, and the support frame 603 moves to one end of the slider 602, so that the pressure plate 606 is away from the top of the crushing box 2. Among them, the triangular fixed plate 611 greatly enhances the overall rigidity and stability of the support frame 603, and can effectively resist the bending moment and vibration generated when the pressure plate 606 is pressed down, preventing The anti-deformation support frame 603 ensures long-term stability and safety of the crushing operation; the stainless steel pull ring 615 provides the operator with a labor-saving and convenient point of force application, making it easier to lift the positioning rod 612 and move the slider 602. At the same time, the stainless steel material also ensures the durability of the pull ring 615 under harsh working conditions; the added corrugated pipe 616 forms a sealed protective cover, isolating the spring 613 from the external environment, effectively preventing dust and debris from entering the interior of the spring 613, avoiding the failure of the spring 613 due to blockage or corrosion, thereby ensuring the reliability and service life of the positioning mechanism.

[0034] By setting up auxiliary structure 7, the handle 76 is first inserted into the circular hole on the disc 75. Rotating the handle 76 causes the screw 72 to rotate via the disc 75. The screw 72, through its thread, moves the positioning frame upwards. During this process, the top frame 73 slides along the inner wall of the bottom frame 71 and the arc surfaces of several auxiliary rods 74. At this time, the overall height of the top frame 73 and the bottom frame 71 relative to the edge of the crushing box 2 increases. Rotating the handle 76 in the opposite direction causes the screw 72 to rotate in the opposite direction, which moves the top frame 73 downwards, reducing the... The overall height of the enclosure can be adjusted by the user according to the needs of the top frame 73 and the bottom frame 71. The combination of the disc 75 and the lever 76 forms a labor-saving lever mechanism, making it easy and effortless to turn the screw 72 and adjust the enclosure height. The pluggable design of the lever 76 also makes it easy to store, avoiding taking up extra space and keeping the work area tidy. The scale 77 provides an intuitive and accurate visual reference for adjusting the enclosure height, enabling the operator to quickly and accurately adjust the enclosure to the required height.
