Description

Technical Field

[0001] This utility model relates to the technical field of waste treatment, specifically to a crushing device for large-item waste treatment equipment. Background Technology

[0002] Garbage is solid waste generated in human daily life and production. Due to its large volume, complex and diverse composition, and its polluting, resource-related, and social characteristics, it needs to be treated in a harmless, resource-recovering, volume-reducing, and socialized manner. If it is not properly treated, it will pollute the environment, affect environmental sanitation, waste resources, undermine the safety of production and life, and disrupt social harmony.

[0003] A search revealed that CN212493159U discloses a crushing device for large-item waste processing equipment. This device includes a processing box with openings at the top and bottom. Through slots are provided on the left and right sides of the processing box, and movable blocks are movably disposed within these slots. An arc-shaped notch is provided on the upper side wall of each movable block near the other, and a crushing rod is disposed within the arc-shaped notch. First crushing teeth are evenly distributed on the surface of the crushing rod. Insertion shafts are provided at the front and rear ends of each crushing rod, and these shafts are movably inserted into the movable blocks. A moving assembly capable of driving the two movable blocks to move relative to each other is provided on the processing box, as well as a driving assembly capable of driving the insertion shafts to rotate. This invention has a simple and reasonable structure, can quickly solve the problem of two crushing rods getting stuck, effectively improves processing efficiency, and avoids jamming during daily crushing that affects crushing efficiency. Simultaneously, it can separately collect stuck waste without affecting subsequent crushing operations.

[0004] However, the following drawbacks still exist in this device and existing technology:

[0005] The existing crushing device has open feed and discharge ports, and no dust suppression structure is installed in the crushing box. Dust generated during waste crushing can easily drift out from the open feed and discharge ports. If the dust is inhaled by workers, it poses a safety hazard and reduces the effectiveness of the crushing device. Utility Model Content

[0006] The purpose of this utility model is to provide a crushing device for large-item waste processing equipment.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A crushing device for a large-item waste processing equipment includes a crushing box, inside which a crushing roller is rotatably connected. A geared motor is located on one side of the crushing box and is connected to the crushing box by screws. The output end of the geared motor is connected to one end of the crushing roller. Pre-reserved openings are provided at both the upper and lower ends of the crushing box. A feeding hopper is located above the crushing box and is connected to the crushing box by screws. A hollow plate is located above the feeding hopper and is fixedly connected to the feeding hopper. At least six spray heads are provided on one side of the hollow plate and are integrated with the hollow plate. A water inlet pipe is located on the other side of the hollow plate, and one end of the water inlet pipe is integrated with the hollow plate.

[0009] By adopting the above technical solution, the garbage is added to the feeding hopper and then falls into the crushing box. The reduction motor drives the crushing roller to rotate at high speed. The rotating crushing roller contacts and collides with the garbage to achieve garbage crushing. The water inlet pipe is connected to the water supply equipment. Water flows from the water inlet pipe into the hollow plate and is then sprayed onto the garbage in the feeding hopper through the spray head to wet the garbage. The water mist is used to remove the dust generated by the garbage crushing and improve the dust reduction effect of the crushing device.

[0010] Furthermore, the inside of the feeding hopper is provided with mounting plates, there are two mounting plates, and the mounting plates are slidably connected to the feeding hopper. Hydraulic cylinders are provided on both sides of the feeding hopper, there are two hydraulic cylinders, and the hydraulic cylinders are connected to the feeding hopper by screws.

[0012] Furthermore, ball bearings are provided on both sides of the mounting plate, and the ball bearings are in rolling connection with the mounting plate, and the ball bearings are in contact with the inner wall of the feeding hopper.

[0013] By adopting the above technical solution, the ball bearings reduce the connection resistance between the mounting plate and the feeding hopper, allowing the mounting plate to move horizontally back and forth better in the feeding hopper.

[0014] Furthermore, a metal mesh plate is provided inside the feeding hopper, and the metal mesh plate is fixedly connected to the feeding hopper. The metal mesh plate is located below the mounting plate.

[0015] By adopting the above technical solution, the metal mesh plate supports the waste added to the hopper and can also screen the crushed waste. Small-volume waste falls into the crushing box, ensuring that the hopper is completely crushed.

[0016] Furthermore, a metal plate is provided inside the crushing box and is fixedly connected to the crushing box. The cross-section of the metal plate is semi-circular and it is positioned below the crushing roller. The metal plate is provided with sieve holes, which are arranged in a rectangular array on the metal plate.

[0017] By adopting the above technical solution, the metal plate catches the crushed waste and screens it. Larger volumes of waste fall onto the metal plate, and the high-speed rotating crushing rollers repeatedly crush the incompletely crushed waste, thereby improving the waste crushing effect.

[0018] Furthermore, a discharge hopper is provided below the crushing box, and the discharge hopper is connected to the crushing box by screws. A water filter plate is provided at the bottom of the discharge hopper, and the water filter plate is integrated with the discharge hopper.

[0019] By adopting the above technical solution, the crushed and qualified waste is discharged along the discharge hopper, the filter plate filters the crushed waste to remove the water mixed in the waste, and then the waste is drained through the drain outlet.

[0020] Furthermore, a support frame is provided below the crushing box, and the support frame is connected to the crushing box by screws. A rubber plate is provided below the support frame, and the rubber plate is fixedly connected to the support frame.

[0021] By adopting the above technical solution, the support frame and rubber plate form a support structure to support the crushing device. The rubber plate also helps to reduce vibration in the crushing device, thereby improving the operational stability of the crushing device.

[0022] In summary, the beneficial technical effects of this utility model are as follows:

[0023] 1. The device uses a hollow plate, spray head, water inlet pipe, filter plate and drain outlet. The water inlet pipe is connected to the water supply equipment.

The device is equipped with at least six spray heads 6, which are integrated with the hollow plate 5. A water inlet pipe 7 is located on the other side of the hollow plate 5, with one end of the water inlet pipe 7 integrated with the hollow plate 5. Waste is added to the feeding hopper 4 and then falls into the crushing box 1. The reduction motor 13 drives the crushing roller 14 to rotate at high speed. The rotating crushing roller 14 contacts and impacts the waste, realizing the crushing treatment of the waste. The water inlet pipe 7 is connected to the water supply equipment, and water flows from the water inlet pipe 7 into the hollow plate 5, and then is sprayed onto the waste in the feeding hopper 4 through the spray heads 6 to wet the waste. The water mist is used to remove the dust generated by the crushing of the waste, thereby improving the dust reduction effect of the crushing device.

[0037] Please see Figure 1 and Figure 2 The feeding hopper 4 has two mounting plates 9 inside, which are slidably connected to the feeding hopper 4. Two hydraulic cylinders 10 are installed on both sides of the feeding hopper 4 and are connected to the feeding hopper 4 by screws. The hydraulic cylinders 10 are located on one side of the mounting plates 9, and their telescopic ends are fixedly connected to the mounting plates 9. A crushing cone 11 is installed on the other side of each mounting plate 9 and is fixedly connected to the mounting plates 9. The crushing cone 11 has an isosceles trapezoidal cross-section. The hydraulic cylinders 10 drive the mounting plates 9 to move horizontally back and forth in the feeding hopper 4. As the two mounting plates 9 move closer together, the crushing cone 11 contacts and impacts the waste, thus pre-crushing the waste. Pre-crushing large pieces of waste is beneficial for subsequent pulverization.

[0038] Please see Figure 7Both sides of the mounting plate 9 are provided with ball bearings 20, and the ball bearings 20 are in rolling connection with the mounting plate 9. The ball bearings 20 are in close contact with the inner wall of the feeding hopper 4.
