Description

Technical Field

[0001] This application relates to the field of crusher technology, and more particularly to a metal crusher. Background Technology

[0002] Metal shredders are key equipment in resource recycling and waste treatment, widely used to crush waste metal materials such as metal cans, metal shavings, and scrapped car bodies to facilitate subsequent transportation, smelting, and recycling. However, in practical applications, these devices often face a thorny problem: due to the irregular shape and high hardness of the shredded metal materials, jamming or entanglement is highly likely. Once jamming occurs, the traditional equipment structure makes maintenance extremely difficult. Utility Model Content

[0003] To solve the above problems, this technical solution provides a metal crusher.

[0004] To achieve the above objectives, the technical solution is as follows:

[0005] A metal shredder, comprising

[0006] The machine body has a crushing chamber, and a driving roller and a driven roller disposed in the crushing chamber;

[0007] The drive roller includes a drive shaft, a drive gear disposed on the drive shaft, and a first crushing wheel disposed on the drive shaft;

[0008] The driven roller includes a driven shaft, a driven gear disposed on the driven shaft, and a second crushing wheel disposed on the driven shaft;

[0009] The disassembly mechanism includes locking blocks sleeved on both ends of the driven shaft and a disassembly channel provided on the machine body. The disassembly channel allows the driven shaft to move to fix the locking blocks to the machine body, or allows the driven shaft to move away from the machine body after the locking blocks are disengaged.

[0010] As described above, a metal crusher has a fixing hole on its body and a locking hole on its locking block. When the locking hole corresponds to the fixing hole, the locking block is connected to the body by a fastener.

[0011] As described above, in a metal crusher, the disassembly channel includes a transverse channel and a longitudinal channel connecting the transverse channel to the outside. The transverse channel allows the driven shaft to move laterally, and the longitudinal channel allows the driven shaft to move longitudinally.

[0012] As described above, in a metal crusher, a plurality of first crushing wheels are spaced apart on the drive shaft, and a plurality of second crushing wheels are spaced apart on the driven shaft. The first crushing wheels and the second crushing wheels are offset so that the second crushing wheels are located between the two first crushing wheels.

[0013] In the metal crusher described above, a collar is fitted on the driven shaft, and the collar is located between the two second crushing wheels.

[0014] As described above, in a metal crusher, the crushing chamber is provided with a plurality of spaced-apart stabilizing plates, which are located between two second crushing wheels.

[0015] In the metal crusher described above, a bearing is provided between the locking block and the driven shaft.

[0016] In the metal crusher described above, the locking block is provided with a support part, and when the locking block is connected to the machine body, the support part is embedded in the transverse channel.

[0017] The beneficial effects of this application are:

[0018] This invention provides a metal crusher where, when the driven roller in the crushing chamber becomes entangled in metal material or jammed by hard objects, the operator does not need to use numerous specialized tools or disassemble multiple complex components. Simply by releasing the locking block from the machine body, the entire driven roller assembly can be easily removed from the machine body through the disassembly channel for maintenance or cleaning. Troubleshooting time is reduced from hours to minutes, significantly minimizing equipment downtime and improving production efficiency.

[0019] The pre-designed disassembly channel provides a clear and direct path for the movement of the driven shaft, making the operation simple and labor-saving. It reduces the requirements for the operator's experience and physical strength, and also avoids the risks of high-intensity disassembly operations in confined spaces, making maintenance work safer.

[0024] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] A metal shredder, comprising

[0026] The machine body 1 has a crushing chamber 2, and a driving roller 3 and a driven roller 4 disposed in the crushing chamber 2;

[0027] The active roller 3 includes an active shaft 31, an active gear 32 disposed on the active shaft 31, and a first crushing wheel 33 disposed on the active shaft 31;

[0028] The driven roller 4 includes a driven shaft 41, a driven gear 42 disposed on the driven shaft 41, and a second crushing wheel 43 disposed on the driven shaft 41;

[0029] The disassembly mechanism 5 includes locking blocks 51 sleeved on both ends of the driven shaft 41, and disassembly channels 52 provided on the body 1. The disassembly channels 52 allow the driven shaft 41 to move to fix the locking blocks 51 to the body 1, or allow the driven shaft 41 to move away from the body 1 after the locking blocks 51 are disengaged.

[0030] This invention provides a metal crusher where, when the driven roller in the crushing chamber becomes entangled in metal material or jammed by hard objects, the operator does not need to use numerous specialized tools or disassemble multiple complex components. Simply by releasing the locking block from the machine body, the entire driven roller assembly can be easily removed from the machine body through the disassembly channel for maintenance or cleaning. Troubleshooting time is reduced from hours to minutes, significantly minimizing equipment downtime and improving production efficiency.

[0031] Furthermore, as a preferred embodiment of this solution and not a limitation, the machine body 1 is provided with a fixing hole 11, and the locking block 51 is provided with a locking hole 511. When the locking hole 511 corresponds to the fixing hole 11, the locking block 51 is connected to the machine body 1 by fasteners. Using fasteners (such as bolts) to pass through the corresponding holes for connection ensures the firmness and stability of the connection of the driven roller in the working state, ensuring the reliability of the crushing operation; at the same time, only a small number of fasteners need to be loosened during disassembly, making the operation simple and quick.

[0032] Furthermore, as a preferred embodiment of this solution and not a limitation, the disassembly channel 52 includes a transverse channel 521 and a longitudinal channel 522 connecting the transverse channel 521 to the outside. The transverse channel 521 allows the driven shaft 41 to move laterally, and the longitudinal channel 522 allows the driven shaft 41 to move longitudinally. The transverse channel is used to adjust the working gap between the driven roller and the driving roller when jammed; the longitudinal channel provides the path for the driven roller assembly to be finally removed or installed. This L-shaped channel design avoids blind operation, making the disassembly and installation process smoother, less strenuous, and more directional.

[0033] Furthermore, as a preferred embodiment of this solution and not a limitation, a plurality of first crushing wheels 33 are spaced apart on the drive shaft 31, and a plurality of second crushing wheels 43 are spaced apart on the driven shaft 41. The first crushing wheels 33 and the second crushing wheels 43 are staggered, so that the second crushing wheel 43 is located between two first crushing wheels 33. The staggered interlocking design allows the material to be subjected to more thorough shearing, tearing, and compression, rather than simple crushing, thereby significantly improving crushing efficiency and crushing effect, resulting in a more uniform output particle size.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, a collar 44 is fitted onto the driven shaft 41, and the collar 44 is located between the two second crushing wheels 43. The collar can prevent the second crushing wheels from moving axially, ensuring the stability of the misaligned meshing structure, while enhancing the overall rigidity of the driven shaft, reducing its deformation risk during operation, and improving the smoothness of equipment operation.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the grinding chamber 2 is provided with a plurality of spaced-apart stabilizing plates 21, which are located between the two second grinding wheels 43. The stabilizing plates can effectively suppress the bending deformation and vibration of the driven shaft caused by uneven grinding force, further ensuring the stability of the working gap between the driving roller and the driven roller, thereby protecting the grinding wheels and maintaining long-term stable grinding performance.

[0036] Furthermore, as a preferred embodiment of this solution and not a limitation, a bearing 53 is provided between the locking block 51 and the driven shaft 41. This allows the driven shaft to rotate freely even when the locking block is fastened to the machine body and remains stationary, thereby ensuring the normal operation of the crushing function and avoiding shaft wear and rotational resistance caused by direct fixing.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, the locking block 51 is provided with a support portion 512. When the locking block 51 is connected to the machine body 1, the support portion 512 is embedded in the transverse channel 521. The support portion embedded in the channel can better withstand the vibration and impact forces generated during the crushing operation, preventing the locking block from shifting or loosening, and ensuring the durability of the connection rigidity. It also supports the machine body, improving its load-bearing capacity.

[0038] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
