Description

Technical Field

[0001] The present application relates to the technical field of scrap steel recycling, and in particular, to a scrap steel crusher with anti-vibration and noise reduction functions. Background Art

[0002] The effective recycling and utilization of waste metal resources can greatly reduce the exploitation and consumption of natural mineral resources, achieving the goals of reducing land occupation, lowering the total social energy consumption, saving investment, protecting the ecological environment, and improving labor productivity. Especially today when natural mineral resources are extremely consumed and becoming increasingly scarce, the status of waste metal resources in the world economy and the sustainable development strategy becomes even more prominent.

[0003] Among them, a scrap steel crusher is a crushing machine used to produce scrap steel crushed materials, mainly for scrapped cars, scrapped household appliances, and thin and light scrap steel. The scrap steel crusher plays an important role in the recycling and treatment of scrap steel, and can effectively crush the scrap steel, facilitating subsequent melting and reuse.

[0004] However, the existing scrap steel crushers extrude and impact the scrap steel during operation, causing vibrations and noises in the crusher housing, which not only affect the health of operators but may also cause noise pollution to the surrounding environment. Summary of the Utility Model

[0005] In order to reduce the vibrations and noises during the operation of the scrap steel crusher, the present application provides a scrap steel crusher with anti-vibration and noise reduction functions.

[0006] The scrap steel crusher with anti-vibration and noise reduction functions provided by the present application adopts the following technical solutions:

[0007] A scrap steel crusher with anti-vibration and noise reduction functions, comprising:

[0008] A base;

[0009] A scrap steel crusher, disposed on the base;

[0010] An anti-vibration assembly, including a lower support fixedly disposed on the base, an upper support fixedly disposed on the scrap steel crusher, and a damping rubber fixedly disposed between the lower support and the upper support;

[0011] A noise reduction mechanism, including a sound insulation cover shell covering the outer surface of the scrap steel crusher, a sound insulation cover plate rotatably disposed at the feeding end of the scrap steel crusher, and a driving assembly for driving the sound insulation cover plate to rotate.

[0012] By adopting the above technical solution, the sound insulation cover shell wrapped around the external of the scrap steel crusher can weaken the noise generated when the scrap steel crusher is running. During operation, the sound insulation cover plate closes the feeding port of the scrap steel crusher, which can further weaken the outward transmission of noise. The damping rubber arranged between the lower support and the upper support can absorb the vibration generated when the scrap steel crusher is running, improve the stability during operation, and play a role in damping.

[0013] Optionally, the anti-vibration component further includes steel plates and lead cores embedded in the damping rubber; the steel plates are arranged in multiple layers in sequence, and both ends of the lead core are fixedly connected to the lower support and the upper support respectively.

[0014] By adopting the above technical solution, the lead core enhances the damping effect. The plastic deformation of the hysteretic damping generated by the lead core can absorb the vibration energy, and can provide a horizontal restoring force through the damping rubber, which helps to weaken the vibration energy. At the same time, the steel plate can provide sufficient bearing capacity, provide rigidity in the vertical direction, and improve the stability during use.

[0015] Optionally, protrusions are fixedly arranged on the steel plate.

[0016] By adopting the above technical solution, the protrusions can increase the tightness of the connection between the steel plate and the damping rubber, making it difficult for the steel plate to slip laterally in the damping rubber, thereby improving the stability during use.

[0017] Optionally, the protrusions on adjacent steel plates are arranged staggeredly.

[0018] By adopting the above technical solution, the staggeredly arranged protrusions can further improve the tightness of the connection between the steel plate and the damping rubber.

[0019] Optionally, a bellows is fixedly arranged between the lower support and the upper support, and the bellows covers the outside of the damping rubber.

[0020] By adopting the above technical solution, the bellows can expand and contract with the deformation of the damping rubber, always maintaining external protection for the damping rubber, preventing external sundries such as dust and moisture from entering the inside of the damping rubber, ensuring its normal operation and extending its service life.

[0021] Optionally, the drive assembly includes an infrared sensor fixedly arranged at the feeding end of the scrap steel crusher, a controller fixedly arranged on the scrap steel crusher, and an electric cylinder hinged on the scrap steel crusher; the controller is electrically connected to the infrared sensor and the electric cylinder, and the piston rod of the electric cylinder is hinged to the sound insulation cover plate.

[0022] By adopting the above technical solution, an infrared sensor is used to detect whether scrap steel enters the feeding port of the scrap steel crusher. When it detects the entry of scrap steel, the infrared sensor transmits an electrical signal to the controller. After receiving the signal, the controller controls the piston rod of the electric cylinder to extend, thereby driving the sound insulation cover plate to rotate, achieving automatic opening and closing, which is convenient for feeding and can maintain the noise reduction effect.

[0023] Optionally, a rubber pad is fixedly arranged on the inner side of the sound insulation cover plate.

[0024] By adopting the above technical solution, the rubber pad has elasticity, which can further increase the sealing performance between the sound insulation cover plate and the feeding port of the scrap steel crusher, prevent noise from leaking out through the gaps, and thus improve the noise reduction effect.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The sound insulation housing covering the outside of the scrap steel crusher can weaken the noise generated during the operation of the scrap steel crusher. During operation, the sound insulation cover plate closing the feeding port of the scrap steel crusher can further weaken the outward transmission of noise. The damping rubber provided between the lower support and the upper support can absorb the vibration generated during the operation of the scrap steel crusher, improve the stability during operation, and play a role in damping.

[0027] 2. An infrared sensor is used to detect whether scrap steel enters the feeding port of the scrap steel crusher. When it detects the entry of scrap steel, the infrared sensor transmits an electrical signal to the controller. After receiving the signal, the controller controls the piston rod of the electric cylinder to extend, thereby driving the sound insulation cover plate to rotate, achieving automatic opening and closing, which is convenient for feeding and can maintain the noise reduction effect.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The technical solutions in the present application will be further described in detail below with reference to the accompanying drawings.

[0033] An embodiment of the present application discloses a scrap steel crusher with anti-vibration and noise reduction functions. Please refer to Figure 1 and Figure 2 , a scrap steel crusher with anti-vibration and noise reduction functions includes a base 1, a scrap steel crusher 2 arranged on the base 1, an anti-vibration component, and a noise reduction mechanism.

[0034] Specifically, please refer to Figure 3 , the anti-vibration component includes a lower support 31 fixedly arranged on the base 1, an upper support 32 fixedly arranged on the scrap steel crusher 2, and a damping rubber 33 fixedly arranged between the lower support 31 and the upper support 32. Through the elastic deformation and damping effect of the damping rubber 33, the vibration generated during the operation of the scrap steel crusher 2 can be absorbed and buffered, thereby reducing the impact of vibration on the scrap steel crusher 2.

[0035] Furthermore, please refer to Figure 3 , the anti-vibration component further includes a steel plate 34 and a lead core 35 embedded inside the damping rubber 33. The steel plates 34 are arranged in multiple layers from top to bottom. Through the arrangement of the multiple layers of steel plates 34, the anti-vibration effect can be further enhanced. Both ends of the lead core 35 are fixedly connected to the lower support 31 and the upper support 32 respectively. Through the shear hysteretic energy dissipation characteristic of the lead core 35, the vibration energy is consumed, thereby achieving the purpose of vibration reduction. The damping rubber 33 is made of a high-damping rubber material and has excellent vibration reduction performance. The steel plate 34 is made of high-strength steel to improve the load-bearing capacity of the anti-vibration component. The lead core 35 is made of pure lead material, and its shear hysteretic energy dissipation characteristic is used to consume the vibration energy.

[0036] Among them, please refer to Figure 3 , a protrusion 341 is fixedly arranged on the steel plate 34. The protrusion 341 can be a dot-shaped protrusion formed on the surface of the steel plate 34, or a strip-shaped or other-shaped protrusion. The protrusion 341 can be integrally formed with the steel plate 34 using the same material, or can be fixed on the steel plate 34 by means of welding or the like. The setting of the protrusion 341 can increase the tightness of the connection between the steel plate 34 and the damping rubber 33, prevent the steel plate 34 from sliding inside the damping rubber 33, and ensure the stability of the anti-vibration component. At the same time, the protrusions 341 on adjacent steel plates 34 are arranged staggeredly. The staggeredly arranged protrusions 341 can further increase the tightness of the connection, make the combination between the steel plate 34 and the damping rubber 33 more firm, and improve the stability of the anti-vibration component during use.

[0037] Even further, please refer to Figure 3, To protect the anti-vibration component, a bellows 36 is fixedly arranged between the lower support 31 and the upper support 32. The bellows 36 is made of a flexible material and can expand and contract with the deformation of the damping rubber 33. The bellows 36 covers the outside of the damping rubber 33, which can prevent external debris from entering the inside of the damping rubber 33 and ensure its normal operation. At the same time, the bellows 36 also has a certain dust-proof and waterproof function, which can further improve the reliability of the anti-vibration component.

[0038] Specifically, please refer to Figure 1 and Figure 2 , The noise reduction mechanism includes a sound insulation cover shell 41 wrapped around the outer surface of the scrap steel crusher 2, a sound insulation cover plate 42 rotatably arranged at the feeding end of the scrap steel crusher 2, and a driving component for driving the sound insulation cover plate 42 to rotate. The sound insulation cover shell 41 is made of sound insulation material and can effectively isolate the noise generated by the scrap steel crusher 2 to prevent it from spreading outward. The sound insulation cover plate 42 is used to open when feeding the scrap steel crusher 2 and close after the feeding ends to maintain the sealing performance of the sound insulation cover shell 41. The sound insulation cover plate 42 is made of sound insulation material and can form a closed space at the feeding end of the scrap steel crusher 2 to further reduce the leakage of noise.

[0039] Among them, please refer to Figure 1 and Figure 2 , The driving component includes an infrared sensor 51 fixedly arranged at the feeding end of the scrap steel crusher 2, a controller 52 fixedly arranged on the scrap steel crusher 2, and an electric cylinder 53 hinged on the scrap steel crusher 2. The infrared sensor 51 is used to detect whether there is scrap steel entering the feeding end of the scrap steel crusher 2 and transmit the detection signal to the controller 52. After receiving the detection signal, the controller 52 judges whether to open or close the sound insulation cover plate 42 according to the preset control logic, and drives the sound insulation cover plate 42 to rotate by controlling the expansion and contraction of the piston rod of the electric cylinder 53, so as to realize the function of automatic opening and closing. This automatically controlled noise reduction mechanism can flexibly adjust the opening and closing state of the sound insulation cover plate 42 according to the actual situation, which is convenient for the input of scrap steel and can effectively isolate noise, improving the intelligence level and the convenience of use of the noise reduction mechanism.

[0040] In addition, a rubber pad is fixedly arranged on the inner side surface of the sound insulation cover plate 42. The rubber pad is made of a rubber material with high elasticity and wear resistance and can closely fit the gap between the sound insulation cover plate 42 and the feeding port of the scrap steel crusher 2. The setting of the rubber pad can further increase the sealing performance of the sound insulation cover plate 42, prevent noise from leaking out from the gap, and improve the noise reduction effect. At the same time, the rubber pad also has a certain buffering effect, which can reduce the impact and noise generated when the sound insulation cover plate 42 closes, making the whole noise reduction mechanism more stable and quiet.

[0041] The implementation principle of the embodiments of this application is as follows: When the scrap crusher is working, the anti-vibration component effectively absorbs and buffers the vibration energy generated by the scrap crusher through the composite structure of the damping rubber 33, the steel plate 34, and the lead core 35, reducing the transmission of vibration to the base 1 and the surrounding environment, and improving the stability and service life of the equipment. At the same time, the noise reduction mechanism significantly reduces the noise generated during the operation of the scrap crusher 2 through the setting of the sound insulation cover 41 and the sound insulation cover plate 42, as well as the sealing effect of the rubber pad, improves the working environment of the operator, and reduces the noise pollution to the surrounding environment. The drive component realizes the automatic opening and closing control of the sound insulation cover plate 42, improving the intelligence level and use convenience of the noise reduction mechanism.

[0042] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
