Description

Technical Field

[0001] This utility model relates to the field of scrap steel processing equipment, and in particular to a scrap steel recycling and crushing component. Background Technology

[0002] As an important recyclable resource, the recycling and processing of scrap steel is of great significance for saving energy and reducing environmental pollution. During the scrap steel recycling process, crushing equipment is needed to break large pieces of scrap steel into smaller sizes to facilitate subsequent sorting, transportation, and smelting.

[0003] Currently, most scrap steel shredding equipment on the market adopts a double-roller crushing structure, which uses two opposing rotating crushing rollers to squeeze and tear the scrap steel falling between them, thereby achieving crushing. However, in practical applications, especially when processing highly resilient materials such as scrap cables and wire ropes, this type of equipment reveals significant limitations. These resilient materials tend to clump together, and when passing through the crushing rollers, they are not only difficult to effectively crush but also tend to become entangled on the rollers, causing equipment blockage, a phenomenon known as "blade entanglement." This not only severely affects crushing efficiency, leading to downtime for cleaning and increased maintenance costs, but may also damage the crushing roller blades, shortening the equipment's lifespan. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a scrap steel recycling and crushing component to solve the technical problems in the prior art.

[0005] To achieve the above objectives, this utility model provides a scrap steel recycling and crushing assembly, including a crushing box, a first crushing roller, and a second crushing roller. The first and second crushing rollers are arranged opposite to each other and rotatably installed inside the upper end of the crushing box. The assembly also includes: A first motor is fixed to the outer wall of the crushing box and its output end is fixedly connected to one end of the second crushing roller; a first gear is fixed to the other end of the second crushing roller. The second gears are symmetrically fixed at both ends of the first crushing roller, and the first gear meshes with the adjacent second gear; Guide grooves are provided on both sides of the middle part of the crushing box. Shearing blades are movably installed on the guide grooves, and a connecting plate is fixed to the top of one end of the shearing blade. A cylindrical cam is rotatably mounted on the outer wall of the crushing box, and the surface of the cylindrical cam is provided with a closed curved groove, and the upper end of the connecting plate is slidably fitted in the groove; A third gear is fixed to one end of the cylindrical cam, and the third gear meshes with the adjacent second gear.

[0006] Preferably, each shearing cutter has a movable groove at its bottom, and a guide block adapted to the movable groove is fixed to the bottom wall of the corresponding guide groove. The shearing cutter moves directionally along the guide groove through the sliding cooperation between the movable groove and the guide block.

[0007] Preferably, a roller is rotatably mounted on the top of the connecting plate, and the roller is rotatably mounted in the groove.

[0008] Preferably, a support plate is fixed to the outer wall of the crushing box, and a groove is formed on the surface of the support plate along the moving direction of the shearing blade, and the lower end of the connecting plate is slidably fitted into the inner wall of the groove.

[0009] Preferably, a positioning plate is fixed to the top of the support plate, and the other end of the cylindrical cam is rotatably mounted on the positioning plate.

[0010] Preferably, the inner wall of the crushing box is symmetrically fixed with a first guide plate, which overlaps the top of the adjacent shearing blade.

[0011] Preferably, the crushing assembly further includes two third crushing rollers, which are symmetrically mounted on the lower end of the crushing box via bearings, and the two third crushing rollers are staggered with the first crushing roller and the second crushing roller in the crushing box. A second motor is fixed to the outer wall of the crushing box and its output end is fixedly connected to one end of the adjacent third crushing roller; A fourth gear is fixed to the other end of the third crushing roller, and two of the fourth gears mesh with each other.

[0012] Preferably, a second guide plate is symmetrically fixed to the inner wall of the upper end of the crushing box, and the second guide plate is located above the first crushing roller and the second crushing roller.

[0013] The beneficial effects of this utility model are as follows: In the primary crushing of scrap steel by the first and second crushing rollers, the reciprocating shearing blade driven by a cylindrical cam can actively cut tough materials (such as tangled cables and wire ropes) before they enter the next stage of crushing or before they wrap around the crushing rollers. This fundamentally avoids equipment blockage and "blade wrapping" caused by material entanglement, significantly improves the equipment's adaptability to complex scrap steel composition and processing continuity, and reduces downtime cleaning and maintenance costs. By adopting a grid-shaped crushing roller structure, in which the first and second crushing rollers arranged horizontally in the upper layer are staggered with the third crushing roller arranged vertically in the lower layer, this design allows the scrap steel material to undergo compression and tearing in different directions within the crushing box, achieving multi-dimensional crushing. This effectively solves the problem of flaky or strip-shaped products that may be generated by traditional single-stage or unidirectional crushing, resulting in more uniform and finer particle size of the crushed material, and significantly improving the crushing effect and efficiency.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0018] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

[0019] The first aspect of this utility model proposes a scrap steel recycling and crushing assembly, such as... Figure 1-6 As shown, the system includes a crushing box 1, a first crushing roller 2, and a second crushing roller 3. The first crushing roller 2 and the second crushing roller 3 are arranged opposite to each other and rotatably mounted inside the upper end of the crushing box 1. It should be noted that both ends of the first crushing roller 2 and the second crushing roller 3 are rotatably mounted on the upper end of the crushing box 1 via bearings to improve the stability of the rotation of the first crushing roller 2 and the second crushing roller 3. The system also includes: A first motor 6 is fixed to the outer wall of the crushing box 1 and its output end is fixedly connected to one end of the second crushing roller 3. A first gear 4 is fixed to the other end of the second crushing roller 3. The second gears 5 are symmetrically fixed at both ends of the first crushing roller 2, and the first gear 4 meshes with the adjacent second gear 5; Guide grooves are provided on both sides of the middle part of the crushing box 1. Shearing blades 7 are movably installed on the guide grooves, and a connecting plate 8 is fixed to the top of one end of the shearing blades 7. A cylindrical cam 10 is rotatably mounted on the outer wall of the crushing box 1, and the surface of the cylindrical cam 10 is provided with a closed curved groove 1001. The upper end of the connecting plate 8 is slidably fitted in the groove 1001. It should be noted that the groove 1001 is annular and has a closed curved structure. When the cylindrical cam 10 rotates, the upper end of the connecting plate 8 will slide along the groove 1001, and under the sliding fit between the bottom of the shearing cutter 7 and the guide groove, the connecting plate 8 drives the shearing cutter 7 to perform reciprocating linear motion. When the two shearing cutters 7 move relative to each other, they can cut materials such as cables and wire ropes. A third gear 11 is fixed to one end of a cylindrical cam 10, and the third gear 11 meshes with the adjacent second gear 5.

[0020] As the output of the first motor 6 drives the second crushing roller 3 to rotate, the first gear 4 at one end of the second crushing roller 3 meshes with the second gear 5 at one end of the first crushing roller 2, so that the other second gear 5 meshes with the third gear 11 at one end of the cylindrical cam 10. The third gear 11 drives the cylindrical cam 10 to rotate. As the cylindrical cam 10 rotates, it drives the connecting plate 8 fixed on the shearing cutter 7 to move back and forth through the groove 1001 on its surface. When the two shearing cutters 7 move relative to each other, materials such as cables and wire ropes that fall into the middle of the crushing box 1 can be cut off. This avoids materials that are too tough, such as clumps of cables and wire ropes, from causing equipment blockage or "blade wrapping" phenomenon. This significantly improves the equipment's adaptability to complex scrap steel and the continuity of processing, and reduces downtime cleaning and maintenance costs.

[0021] In this embodiment: each shearing cutter 7 has a movable groove at its bottom, and a guide block adapted to the movable groove is fixed to the bottom wall of the corresponding guide groove. The shearing cutter 7 moves directionally along the guide groove through the sliding engagement of the movable groove and the guide block. It should be added that the bottom of the shearing cutter 7 is slidably mounted on the guide block on the guide groove of the crushing box 1 through the movable groove, which is used to limit the sliding direction of the shearing cutter 7 and ensure the stability of the shearing cutter 7 when it moves.

[0022] In this embodiment, a roller is rotatably mounted on the top of the connecting plate 8, and the roller is rotatably mounted in the groove 1001. The rotatable mounting of the roller on the top of the connecting plate 8 in the groove 1001 reduces frictional interference between the connecting plate 8 and the curved groove 1001.

[0023] In this embodiment: a support plate 9 is fixed to the outer wall of the crushing box 1, and a groove 901 is formed on the surface of the support plate 9 along the moving direction of the shearing blade 7. The lower end of the connecting plate 8 is slidably fitted into the inner wall of the groove 901. The support plate 9 provides support for the movement of the connecting plate 8, thereby enhancing stability.

[0024] In this embodiment, a positioning plate 12 is fixed to the top of the support plate 9, and the other end of the cylindrical cam 10 is rotatably mounted on the positioning plate 12. The positioning plate 12 further improves the rotational stability of the cylindrical cam 10.

[0025] In this embodiment: A first guide plate 13 is symmetrically fixed to the inner wall of the crushing chamber 1, and the first guide plate 13 overlaps the top of the adjacent shearing blade 7. During two opposite movements, the crushed material accumulated on the top of the shearing blade 7 is scraped by the first guide plate 13 and hung down to the lower part of the crushing chamber 1 to avoid material accumulation.

[0026] In this embodiment, the crushing assembly also includes two third crushing rollers 14, which are symmetrically mounted on the lower end of the crushing box 1 via bearings. The two third crushing rollers 14 are staggered with the first crushing roller 2 and the second crushing roller 3 in the crushing box 1. It should be added that the two third crushing rollers 14 are staggered with the first crushing roller 2 and the second crushing roller 3 in the crushing box 1 in a grid pattern to facilitate the dimensional crushing of scrap steel. A second motor 16 is fixed to the outer wall of the crushing box 1 and its output end is fixedly connected to one end of the adjacent third crushing roller 14; The fourth gear 15 is fixed to the other end of the third crushing roller 14, and the two fourth gears 15 mesh with each other.

[0027] After the first crushing roller 2 and the second crushing roller 3 complete the primary crushing of the scrap steel, the output end of the second motor 16 drives the third crushing roller 14 to rotate. The two third crushing rollers 14 rotate relative to each other under the transmission of the fourth gear 15 to carry out secondary crushing of the scrap steel. This arrangement of the first crushing roller 2 and the second crushing roller 3 arranged laterally and opposite to each other at the feed end of the crushing box 1, and the third crushing roller 14 arranged longitudinally and opposite to each other in the material passage below, forms a grid-like staggered layout, which crushes the scrap steel in multiple dimensions. This effectively solves the problem of flaky or strip-shaped products that may be generated by traditional single-stage or unidirectional crushing, making the particle size of the crushed material more uniform and finer, and significantly improving the crushing effect and efficiency.

[0028] In this embodiment, a second guide plate 17 is symmetrically fixed to the inner wall of the upper end of the crushing box 1, and the second guide plate 17 is located above the first crushing roller 2 and the second crushing roller 3. This is to guide the scrap steel entering the crushing box 1 to the gap between the two crushing rollers, thereby improving the crushing efficiency.
