Description

Technical Field

[0001] This utility model relates to the field of dual-shaft shredder technology, and in particular to a dual-shaft high-efficiency shredder. Background Technology

[0002] A twin-shaft shredder is a mechanical device used for the efficient crushing and shredding of various materials. It mainly consists of two opposing rotating shafts and cutters mounted on the shafts. A motor drives the two shafts to rotate in opposite directions. After the material enters the crushing chamber, it is simultaneously gripped by the two cutters and torn, squeezed, and sheared, thus breaking the material into smaller particles or flakes.

[0003] Most existing dual-shaft shredders typically use traditional methods such as interference fit, key connection, or bolt fastening to assemble the shredding shaft with bearings, couplings, and other components. This design makes the connections between components tight and complex. For example, the interference fit between the shaft and bearing relies on extremely high pressure for assembly, and disassembly requires specialized hydraulic disassembly equipment or heating tools. The operation is not only cumbersome but may also damage the shaft or bearing due to improper operation. In some shredders, the shredding shaft is nested with seals, gears, and other components inside the housing. Disassembly requires the removal of a large number of external components, increasing the steps and difficulty of disassembly, resulting in a time-consuming and technically demanding process. In view of this, we propose a dual-shaft high-efficiency shredder. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a dual-shaft high-efficiency shredder to solve the technical problem that most existing dual-shaft shredders usually use traditional methods such as interference fit, key connection or bolt fastening to assemble the shredding shaft with bearings, couplings and other components. This design makes the connection between the components tight and complex.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a dual-shaft high-efficiency shredder is designed, including a machine box, an adjustment component is provided on the outside of the machine box, a first shredding roller is provided on the rear side inside the machine box, a second shredding roller is provided in front of the first shredding roller, a set of limiting mechanisms are symmetrically provided on both sides of the first shredding roller and the second shredding roller, a first motor is connected to the outer end of the left limiting mechanism of the first shredding roller, and a second motor is connected to the outer end of the left limiting mechanism of the second shredding roller;

[0006] The limiting mechanism includes a T-shaped block, which is fixed to the end of the first shredding roller or the second shredding roller. A limiting frame is attached to the outside of the T-shaped block, and an I-shaped frame is fixed to one side of the limiting frame.

[0007] Preferably, the limiting mechanism further includes a cylindrical frame, a set of cylindrical frames symmetrically fixed on the front and rear surfaces of the limiting frame, a set of U-shaped limiting rods symmetrically passing through the inside of the set of cylindrical frames, a limiting ring plate fixedly sleeved on the surface of the U-shaped limiting rod, a lever fixedly connected to the lower end of the U-shaped limiting rod, and a spring provided on one side of the limiting ring plate.

[0008] Preferably, the limiting frame is H-shaped, and the bottom of the T-shaped block is matched and engaged inside the limiting frame.

[0009] Preferably, the inner side of the T-shaped block is provided with a limiting groove that matches the end of the U-shaped limiting rod, and the upper end of the U-shaped limiting rod can be matched and engaged in the limiting groove on the inner side of the T-shaped block after passing through one side of the limiting frame.

[0010] Preferably, the U-shaped limiting rod is formed into an elastic structure by a limiting ring plate, a spring, and a cylindrical frame, and the outer wall of the limiting ring plate matches and fits the inner wall of the cylindrical frame.

[0011] Preferably, the adjustment component includes a multi-stage hydraulic cylinder, with two sets of the multi-stage hydraulic cylinders symmetrically arranged on the front and rear sides of the machine housing surface. A set of bending plates is symmetrically connected to the movable ends of the two sets of multi-stage hydraulic cylinders. A set of feeding racks is symmetrically fixed to the upper end of one set of bending plates, and a set of sliding plates is symmetrically fixed to the bottom of the feeding racks. A sliding groove is attached to the outer side of the sliding plates.

[0012] Preferably, the feed rack has a sliding structure formed by a sliding plate and a sliding groove, and the sliding groove and the machine casing are integrally formed.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model effectively drives a set of U-shaped limiting rods to move outward by spreading outward with a set of paddles. At this time, the upper end of the U-shaped limiting rod gradually separates from the inner side of the T-shaped block. At the same time, the limiting ring plate applies pressure to the spring. When the upper end of the U-shaped limiting rod is hidden inside the limiting frame, the T-shaped block can move outward directly without restriction and separate from the limiting frame, which facilitates the quick disassembly of the first shredding roller or the second shredding roller. During installation, the T-shaped block is inserted into the limiting frame after spreading outward with a set of paddles. Then, the paddles are released. Under the influence of the spring's rebound force, the upper end of the U-shaped limiting rod pops out and effectively engages in the limiting groove inside the T-shaped block, completing the quick installation of the first shredding roller or the second shredding roller.

[0015] 2. In the normal feeding state of this utility model, a set of feeding racks are closely fitted together, which facilitates the precise transfer of materials. When it is necessary to inspect and replace the first shredding roller and the second shredding roller inside the machine box, the bending plate is effectively moved outward by the multi-stage hydraulic cylinder, thereby moving the set of feeding racks away from each other, so as to expose the first shredding roller and the second shredding roller inside the machine box for subsequent inspection and replacement. During the movement and adjustment of the feeding rack, the slide effectively guides the slide plate, improving the movement stability of the feeding rack. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0025] A dual-shaft high-efficiency shredder, see [link / reference] Figures 1 to 5 The device includes a chassis 1, an adjustment assembly 2 on the outside of the chassis 1, a first shredding roller 3 on the rear side inside the chassis 1, a second shredding roller 4 in front of the first shredding roller 3, a set of limiting mechanisms 5 symmetrically provided on both sides of the first shredding roller 3 and the second shredding roller 4, a first motor 6 connected to the outer end of the left limiting mechanism 5 of the first shredding roller 3, and a second motor 7 connected to the outer end of the left limiting mechanism 5 of the second shredding roller 4;

[0026] The limiting mechanism 5 includes a T-shaped block 501, which is fixed to the end of the first shredding roller 3 or the second shredding roller 4. A limiting frame 502 is attached to the outer side of the T-shaped block 501. The limiting frame 502 is H-shaped, and the bottom of the T-shaped block 501 is matched and engaged inside the limiting frame 502. An I-shaped frame 503 is fixed to one side of the limiting frame 502. The limiting mechanism 5 also includes a cylindrical frame 504. A set of cylindrical frames 504 are symmetrically fixed to the front and rear surfaces of the limiting frame 502. A set of U-shaped limiting rods 505 are symmetrically passed through the inside of the set of cylindrical frames 504. Furthermore, the inner side of the T-shaped block 501 is open... A limiting groove matching the end of the U-shaped limiting rod 505 is provided. After the upper end of the U-shaped limiting rod 505 passes through one side of the limiting frame 502, it can be matched and engaged in the limiting groove inside the T-shaped block 501. A limiting ring plate 506 is fixedly sleeved on the surface of the U-shaped limiting rod 505. A paddle 507 is fixedly connected to the lower end of the U-shaped limiting rod 505. A spring 508 is provided on one side of the limiting ring plate 506. Furthermore, the U-shaped limiting rod 505 forms an elastic structure with the cylinder frame 504 through the limiting ring plate 506, the spring 508, and the outer wall of the limiting ring plate 506 matches and fits the inner wall of the cylinder frame 504. This invention effectively drives a set of U-shaped limiting rods 505 outward by spreading outward a set of levers 507. At this time, the upper end of the U-shaped limiting rod 505 gradually separates from the inner side of the T-shaped block 501. Simultaneously, the limiting ring plate 506 applies pressure to the spring 508. When the upper end of the U-shaped limiting rod 505 is concealed inside the limiting frame 502, the T-shaped block 501 can move outward without restriction and separate from the limiting frame 502, which facilitates the quick disassembly of the first shredding roller 3 or the second shredding roller 4. During installation, based on spreading outward a set of levers 507, the T-shaped block 501 is inserted into the limiting frame 502. Then, the levers 507 are released. Under the influence of the spring 508's rebound force, the upper end of the U-shaped limiting rod 505 pops out and effectively engages in the limiting groove inside the T-shaped block 501, completing the quick installation of the first shredding roller 3 or the second shredding roller 4.

[0027] It is worth noting that the adjustment component 2 includes a multi-stage hydraulic cylinder 201. Two sets of multi-stage hydraulic cylinders 201 are symmetrically arranged on the front and rear sides of the surface of the machine housing 1. A set of bending plates 202 are symmetrically connected to the movable ends of the two sets of multi-stage hydraulic cylinders 201. A set of feeding racks 203 are symmetrically fixed at the upper end of the set of bending plates 202. A set of sliding plates 204 are symmetrically fixed at the bottom of the feeding racks 203. A sliding groove 205 is attached to the outer side of the sliding plate 204. The feeding rack 203 forms a locking and sliding structure with the sliding plate 204 and the sliding groove 205. The sliding groove 205 is integrally formed with the machine housing 1. In the normal feeding state of this utility model, a set of feeding racks 203 are closely fitted together, which facilitates the precise transfer of materials. When it is necessary to inspect and replace the first shredding roller 3 and the second shredding roller 4 inside the machine box 1, the multi-stage hydraulic cylinder 201 effectively drives the bending plate 202 to move outward, thereby moving the set of feeding racks 203 away from each other, so as to expose the first shredding roller 3 and the second shredding roller 4 inside the machine box 1 for subsequent inspection and replacement. During the movement and adjustment of the feeding rack 203, the slide groove 205 effectively guides the slide plate 204, improving the movement stability of the feeding rack 203.

[0028] Working principle: Under normal feeding conditions, a set of feeding racks 203 are closely fitted together, allowing for precise material transfer. Then, the first motor 6 drives the first shredding roller 3 to rotate clockwise, and the second motor 7 drives the second shredding roller 4 to rotate counterclockwise, thus efficiently crushing and shredding the material. When it is necessary to inspect or replace the first shredding roller 3 and the second shredding roller 4 inside the machine housing 1, the multi-stage hydraulic cylinder 201 drives the bending plate 202 to move outward, thereby causing the set of feeding racks 203 to move away from each other. At this time, the first shredding roller 3 and the second shredding roller 4 inside the machine housing 1 are exposed, facilitating inspection and replacement. By pushing a set of levers 507 outward, a set of U-shaped limit rods 505 moves outward. At this time, the upper end of the U-shaped limit rods 505 gradually separates from the T-shaped... Inside block 501, the limiting ring plate 506 applies pressure to spring 508. When the upper end of U-shaped limiting rod 505 is concealed inside limiting frame 502, T-shaped block 501 can move outward directly and separate from limiting frame 502 without restriction, allowing for quick disassembly of the first shredding roller 3 or the second shredding roller 4. During installation, after opening a set of pry bars 507 outward, T-shaped block 501 is inserted into limiting frame 502. Then, the pry bars 507 are released, and the upper end of U-shaped limiting rod 505 pops out and engages in the limiting groove inside T-shaped block 501 due to the rebound force of spring 508, completing the quick installation of the first shredding roller 3 or the second shredding roller 4. Afterward, the bending plate 202 and feeding frame 203 are returned to their positions by the multi-stage hydraulic cylinder 201.
