Description

Technical Field

[0001] This utility model relates to the field of waste treatment equipment technology, specifically to a shock absorption device for the rotating drum of a waste sorting and dewatering machine. Background Technology

[0002] Waste sorting systems are an indispensable technology in modern urban waste management. They efficiently and accurately separate recyclables from hazardous waste through automation and intelligent methods. The dewatering machine within a waste sorting system is a specialized device for removing moisture from waste. It separates the liquid components from the solid components of the waste through methods such as mechanical extrusion, centrifugal separation, or thermal evaporation, thereby reducing the volume and weight of the waste, improving waste processing efficiency, and facilitating subsequent recycling or landfill disposal.

[0003] The dewatering machine in a waste sorting system plays a crucial role in improving resource recovery rates, but it also has some drawbacks. The dewatering machine's rotating drum uses a shaftless rotating structure, which makes it difficult to ensure the stability of the drum as the amount of material processed increases or the rotation speed rises. Utility Model Content

[0004] To address the problems existing in the background art, this utility model provides a shock-absorbing device for the rotating drum of a waste sorting and dewatering machine, which includes: a contact wheel, a connecting plate, a spring, and a mounting plate;

[0005] A mounting shell is movably connected to the lower middle part of the connecting plate. A contact wheel is fixedly connected inside the mounting shell. A symmetrical guide rod is fixedly connected to the upper part of the connecting plate. A spring is sleeved on the outside of the guide rod. A mounting plate is fixedly connected to the upper end of the spring. Four first screws are connected through the mounting plate. Four No. 1 nuts are provided on the first screws. The mounting plate is installed on the bracket through the first screws.

[0006] In the preferred embodiment, linear bearings are provided on both sides above the mounting plate, and the upper parts of the two linear bearings are connected by a strip plate. A second screw is provided through the strip plate, and three No. 2 nuts are provided on the second screw.

[0007] In the preferred embodiment, a third screw is fixedly installed on both sides above the middle of the connecting plate, and a No. 3 nut is provided at both ends of the third screw. The installation positions of the third screw and the second screw are coaxial, and the installation positions of the guide rod and the linear bearing are coaxial.

[0008] The beneficial effects achieved by this utility model are as follows:

[0009] 1. The spring in this shock absorption device can effectively absorb and reduce the vibration generated by the rotating drum during operation, ensuring the stability of the rotating drum, improving the working efficiency of the dewatering machine, and thus increasing the resource recovery rate.

[0010] 2. This device improves the stability of the rotating drum through the synergistic action of components such as the contact wheel, connecting plate, spring, and mounting plate, thereby ensuring the smooth operation of the dewatering machine's rotating drum under high load and high speed conditions. The contact wheel can rotate freely and maintain the same speed as the rotating drum, reducing wear and energy loss caused by speed differences.

[0011] 3. The design of the first, second, and third screws, along with different types of nuts, enhances the durability and reliability of the entire shock absorption device, allowing for adjustment under different working conditions to meet various material handling needs.

[0012] 4. Linear bearings provide a low-friction sliding surface, allowing relative movement between the contact wheel and the rotating cylinder while reducing friction and wear. They also help ensure smooth movement of the contact wheel and reduce abnormal movement of the contact wheel caused by vibration or offset of the rotating cylinder, thereby maintaining the stability of the rotating cylinder.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Reference Figures 1-3A shock-absorbing device for the rotating drum of a waste sorting and dewatering machine includes: a contact wheel 2, a connecting plate 3, a spring 4, and a mounting plate 5; a mounting shell 1 is movably connected to the lower middle part of the connecting plate 3, the contact wheel 2 is fixedly connected inside the mounting shell 1, a symmetrical guide rod 14 is fixedly connected to the upper part of the connecting plate 3, a spring 4 is sleeved on the outside of the guide rod 14, the mounting plate 5 is fixedly connected to the upper end of the spring 4, and four first screws 7 are connected through the mounting plate 5. Four nuts 11 are provided on the first screws 7, and the mounting plate 5 is mounted on the bracket 16 through the first screws 7.

[0020] Linear bearings 6 are installed on both sides above the mounting plate 5. The two linear bearings 6 are connected by a strip plate 8 at the top. A second screw 9 is installed through the strip plate 8. Three second nuts 12 are installed on the second screw 9.

[0021] A third screw 10 is fixedly installed on both sides above the middle of the connecting plate 3. The third screw 10 has a No. 3 nut 13 at both ends. The installation position of the third screw 10 is coaxial with that of the second screw 9. The guide rod 14 is coaxial with that of the linear bearing 6.

[0022] The movement process of the shock-absorbing device for the rotating drum of a waste sorting and dewatering machine according to this utility model is as follows: The first screw 7 fixes the device to the bracket 16 outside the rotating drum 15. The first screw 7 is provided with multiple No. 1 nuts 11. After adjusting to a suitable position, the position of the first screw 7 can be fixed by tightening or loosening these nuts. The distance between the contact wheel 2 and the rotating drum 15 can be adjusted by the first screw 7 to ensure that the distance between the contact wheel 2 and the rotating drum 15 remains stable. The contact wheel 2 can rotate freely and keep the same speed as the rotating drum 15, reducing wear and energy loss caused by speed difference.

[0023] After the first screw 7 is fixed, the third screw 10 can be adjusted by adjusting the third nut 13 to ensure that its position on the bracket 16 is stable. The setting of the third screw 10 enhances the structural strength of the connecting plate 3, helps to withstand the force generated by the rotating cylinder 15 during operation, and reduces the deformation or damage of the connecting plate 3.

[0024] The second screw 9 changes the pre-compression of the spring 4 by adjusting its position within the strip plate 8. When the second screw 9 is screwed in or out, it pushes the strip plate 8 upward or downward, causing the mounting plate 5 and the upper end of the spring 4 to move together, thereby changing the pre-compression of the spring 4. After adjusting to the desired pre-compression, the position of the second screw 9 is fixed by the second nut 12 provided on the second screw 9, ensuring that the adjusted pre-compression of the spring 4 remains unchanged. By changing the pre-compression, the stiffness of the spring 4 can be changed, thus adapting to different working conditions and material characteristics.

[0025] The linear bearing 6 provides a low-friction sliding surface, allowing relative movement between the contact wheel 2 and the rotating cylinder 15 while reducing friction and wear. It also helps ensure smooth movement of the contact wheel 2 and reduces abnormal movement of the contact wheel 2 caused by vibration or offset of the rotating cylinder 15, thereby maintaining the stability of the rotating cylinder 15. The strip plate 8 serves to connect and transmit forces and also helps to evenly distribute the buffering force of the spring 4, reducing the vibration of the rotating cylinder 15 and improving the stability of the entire device. The linear bearing 6 and the strip plate 8 assist in positioning and buffering, further ensuring the stability of the rotating cylinder 15 and reducing vibration.

[0026] During high-speed rotation of the rotating drum 15, due to the irregularity and uneven distribution of the material, the rotating drum 15 will vibrate or shift. Through the close cooperation between the contact wheel 2 and the rotating drum 15, when the rotating drum 15 vibrates or shifts, the contact wheel 2 will also generate corresponding displacement. When the contact wheel 2 moves due to the vibration of the rotating drum 15, the guide rod 14 will push or pull the spring 4, causing the spring 4 to be compressed or stretched. When the spring 4 is compressed, it will store energy and generate a restoring force proportional to the displacement. This restoring force can offset the vibration of the rotating drum 15 and reduce the impact on the entire device. Due to the buffering effect of the spring 4, the vibration of the rotating drum 15 is attenuated, thereby reducing the impact on other parts of the dewatering machine, improving the stability and working efficiency of the equipment. The spring 4 effectively absorbs and reduces the vibration generated by the rotating drum 15 during operation, ensuring the stability of the rotating drum 15, improving the working efficiency of the dewatering machine, reducing the wear of parts, and extending the service life of the equipment.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
