[0002] A metal shredder is a machine specifically designed for crushing scrap metal materials, playing a crucial role in the field of metal recycling and processing. In the process of crushing scrap metal, the scrap metal is fed into the shredder and then rapidly crushed to obtain metal powder and other materials.

[0003] The gear transmission transmits speed to the driven shaft, causing the moving blades on the drive shaft to move relative to the stationary blades on the housing. The helical blades on the drive shaft are arranged in an alternating pattern, so when the material enters, it will be subjected to squeezing, tearing, and shearing actions simultaneously, thereby achieving the pulverizing effect.

[0004] In the current technology, during the crushing of metal materials by a crusher, the blades inside the crusher have a fixed spacing. When encountering metals of different sizes and textures, the wear of the crushing blades will increase during the crushing process, thereby reducing the crushing cost and efficiency. Therefore, in order to address the above problems, a crusher blade and a crusher having the crusher blade are proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Specific implementation examples are given below.

A mounting plate 22 is fixedly connected to the end of the rotating shaft 21. An installation unit is provided inside the mounting plate 22. A rotating rod 23 is mounted to the end of the mounting plate 22 via the installation unit. A sliding groove 24 is provided at the end of the rotating rod 23. A motor 25 is fixedly connected to the inner wall of the rotating rod 23. A lead screw 26 is fixedly connected to the output end of the motor 25, and the other end of the lead screw 26 is rotatably connected to the inner wall of the rotating rod 23. The surface of the lead screw 26 has positive and negative threads, and several sets of these threads are provided. The lead screw 26 and a slider 28 are connected via a lead screw and nut pair and are symmetrically arranged. A limit plate 27 is fixedly connected to the end of the lead screw 26. A fixing rod 29 is fixedly connected to the top of the slider 28, and the fixing rod 29 is slidably connected to the inner wall of the sliding groove 24. A crushing blade 31 is fixedly connected to the top of the rod 29; a limiting block 32 is fixedly connected to the middle of the lead screw 26. During operation, when metal needs to be crushed, due to the different materials and sizes of the metals, it is necessary to adjust the spacing of the crushing blades 31 before crushing to reduce wear on the crushing blades 31. By turning on the motor 25 to drive the lead screw 26 to rotate, the lead screw 26 drives the slider 28 and the fixed rod 29 to move, causing the fixed rod 29 to move the crushing blades 31 towards the center, thereby adjusting the spacing between the crushing blades 31 to quickly crush metals of different textures. By adjusting the blade spacing, the particle size of the crushed material can be directly controlled; when larger particles are needed, the blade spacing can be appropriately increased; if finer crushing is required, the spacing can be decreased. This adjustment method can meet different production needs and improve the applicability of the crusher.

[0030] Furthermore, such as Figures 1-4As shown, the installation unit includes a slot 41; slots 41 are provided inside the mounting plate 22 and at the end of the crushing blade 31; a locking rod 42 is slidably connected inside the slot 41; guide grooves 46 are provided inside the locking rod 42 and the mounting plate 22; a guide block 47 is slidably connected inside the guide groove 46; a pressing block 45 is slidably connected inside the locking rod 42; a guide rod 44 is fixedly connected to the end of the pressing block 45; a locking plate 43 is fixedly connected to the end of the guide rod 44; during operation, when it is necessary to quickly install and fix the crushing blade 31, the... The crushing blade 31 is placed on the end of the mounting plate 22 and aligned with each other. Then, by pushing the clamping plate 43, the guide rod 44 and the extrusion block 45 are inserted into the inside of the clamping rod 42. During the insertion process, the end of the guide block 47 is extruded and retracted into the guide groove 46 for locking and fixing. This fixes the crushing blade 31 to the end of the mounting plate 22. Then, by starting the drive device 1, the mounting plate 22 and the crushing blade 31 are driven to rotate rapidly, thereby driving the crushing blade 31 to rotate rapidly to quickly crush the metal.

[0031] Furthermore, such as Figures 1-4 As shown, the clamping rod 42 has a cavity 51 inside; a fixing plate 52 is slidably connected inside the cavity 51, and one end of the fixing plate 52 is fixed to the driving end of the guide block 47; a spring 53 is fixed to the side end of the fixing plate 52, and the other end of the spring 53 is fixed to the inner side wall of the cavity 51; during operation, when the extrusion block 45 extrudes the guide block 47 and retracts into the guide groove 46, it drives the fixing plate 52 to slide into the cavity 51, so that the spring 53 generates elastic force during the sliding of the cavity 51. When it is necessary to disassemble the crushing blade 31, by pulling the clamping plate 43, the guide rod 44 and the extrusion block 45 slide out from the inside of the clamping rod 42, so that the spring 53 generates elastic force to push the fixing plate 52 to slide to the side end, so that the fixing plate 52 drives the guide block 47 to retract from the inside of the guide groove 46 into the inside of the clamping rod 42. Then, by pulling the clamping rod 42 out from the inside of the clamping groove 41, the crushing blade 31 is removed from the end of the mounting plate 22 for quick disassembly.

[0032] Furthermore, such as Figures 1-4 As shown, a limiting ring 61 is fixedly connected to the inner wall of the clamping rod 42; the end of the clamping plate 43 is hinged to a guide rod 44 by a torsion spring and is located at the bottom of the limiting ring 61; during operation, when the clamping plate 43 drives the guide rod 44 to insert into the interior of the clamping rod 42, the fixing block 62 is squeezed to make the fixing block 62 pass over the limiting ring 61. When it passes over the limiting ring 61, the clamping rod 42 is released, so that the clamping rod 42 is rotated and locked at the bottom of the limiting ring 61 by the elastic force generated by the torsion spring, so as to limit and fix it. When disassembly is required, the fixing block 62 is squeezed to slide off from the bottom of the limiting ring 61, and the clamping plate 43 is pulled outward for disassembly.

[0033] Please see Figures 5-7 As shown, a crusher is characterized in that: the crusher is suitable for the crusher blades described in the above claims; the ends of the drive device 1 and the rotating shaft 21 are provided with a crusher housing 71; the top of the crusher housing 71 is fixedly connected to a feed inlet 72; the inner sidewall of the feed inlet 72 is hinged with a protective plate 8 by a torsion spring; during operation, the protective plate 8 installed on the inner sidewall of the feed inlet 72 provides protection and prevents splashing, reducing the splashing problem of metal during the crushing process.

[0034] Furthermore, such as Figures 5-7 As shown, a cleaning rod 74 is fixedly connected to the inner wall of the crusher housing 71; cleaning blocks 75 are fixedly connected to both sides of the cleaning rod 74 and are located at the ends of the crushing blades 31; during operation, by installing the cleaning rod 74 and cleaning blocks 75 on the inner wall of the crusher housing 71, when the crushing blades 31 rotate to adjust the spacing, the cleaning blocks 75 on both sides of the cleaning rod 74 clean the debris remaining on the surface of the crushing blades 31, thereby improving the working efficiency of the crushing blades 31.

[0035] Furthermore, such as Figures 5-7 As shown, a base 73 is fixedly connected to the bottom of the crusher housing 71; during operation, the base 73 installed at the bottom of the crusher housing 71 serves to provide support and fixation.

[0036] Working Principle: When metal needs to be crushed, due to the different materials and sizes of the metals, the spacing of the crushing blades 31 needs to be adjusted before crushing to reduce wear on the blades. By turning on the motor 25, the lead screw 26 rotates, causing the slider 28 and the fixed rod 29 to move. The fixed rod 29 then moves the crushing blades 31 towards the center, adjusting the spacing between the blades 31 to quickly crush metals of different textures. By adjusting the blade spacing, the particle size of the crushed material can be directly controlled. Larger particles can be achieved by increasing the blade spacing; finer crushing can be achieved by decreasing the spacing. This adjustment method can... This design can meet different production needs and improve the applicability of the crusher. When it is necessary to quickly install and fix the crushing blades 31, the crushing blades 31 are placed on the end of the mounting plate 22 and aligned with each other. Then, by pushing the clamping plate 43, the guide rod 44 and the extrusion block 45 are inserted into the clamping rod 42. During the insertion process, the end of the guide block 47 is squeezed, causing the guide block 47 to be squeezed and retracted into the guide groove 46 for locking and fixing. This fixes the crushing blades 31 to the end of the mounting plate 22. Then, by starting the drive device 1, the mounting plate 22 and the crushing blades 31 are driven to rotate rapidly, thereby driving the crushing blades 31 to rotate rapidly for rapid crushing of metal. When the extrusion block 45 squeezes the guide block 47 and retracts into the guide groove 46... When the clamping plate 43 moves into the cavity 51, it causes the fixing plate 52 to slide into the cavity 51. During the sliding process, the spring 53 is compressed and generates elastic force. When it is necessary to disassemble the crushing blade 31, the clamping plate 43 is pulled to drive the guide rod 44 and the squeezing block 45 to slide out from the inside of the clamping rod 42. This causes the spring 53 to generate elastic force and push the fixing plate 52 to slide to the side. This causes the fixing plate 52 to drive the guide block 47 to retract from the inside of the guide groove 46 into the inside of the clamping rod 42. Then, by pulling the clamping rod 42 out of the inside of the groove 41, the crushing blade 31 can be removed from the end of the mounting plate 22 for quick disassembly. When the clamping plate 43 drives the guide rod 44 to insert into the inside of the clamping rod 42, the clamping block 62 is squeezed and causes the clamping block 62 to pass over the limiting ring 61. When the limit ring 61 is passed, the locking rod 42 is released, allowing the locking rod 42 to rotate and engage with the bottom of the limit ring 61 through the elastic force generated by the torsion spring, thus limiting and fixing it. When disassembly is required, the locking block 62 is squeezed to slide off from the bottom of the limit ring 61, and the locking plate 43 is pulled outward for disassembly. A protective plate 8 is installed on the inner wall of the feed inlet 72 to protect against splashing and reduce metal splashing during the crushing process. A cleaning rod 74 and a cleaning block 75 are installed on the inner wall of the crusher housing 71. When the crushing blade 31 rotates to adjust the spacing, the cleaning blocks 75 on both sides of the cleaning rod 74 clean the residual debris on the surface of the crushing blade 31, improving the working efficiency of the crushing blade 31.A base 73 is installed at the bottom of the crusher housing 71 to provide support and fixation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
