Description

Technical Field

[0001] The invention relates to the technical field of scrap iron processing, and in particular to an anti-clogging scrap iron crushing device. Background Art

[0002] In the process of resource recycling, the crushing of scrap iron is particularly important. The squeezing and tearing functions of the crushing roller can effectively break down the scrap iron into smaller fragments. This link not only helps to reduce the burden of scrap iron on the environment, but also can transform these scrap metals into new resources, thus promoting the recycling and sustainable development of resources.

[0003] In the process of scrap iron crushing, the crushing equipment often becomes clogged due to the high hardness and large volume of the crushed materials. When scrap iron is stuck inside the crushing roller, it is difficult to remove it from the equipment, and there are significant safety risks in manually removing the clogged scrap iron. In addition, the distance between the two crushing rollers of some models is fixed, or the two crushing rollers can move away from each other to expand the gap, so that the uncrushed scrap iron dropped during the unblocking process will be directly mixed into the crushed iron slag, which results in the mixing of processed products and unprocessed materials after the blockage is unblocked, thereby reducing processing efficiency and product quality. Since the problem of scrap iron blockage is more serious, external pressure is often required to assist the waste to be discharged from the inside of the equipment. At the same time, since the upper conveyor belt continues to run, even in the case of blockage, scrap iron continues to enter the equipment, aggravating the blockage. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the prior art has the disadvantages that scrap iron is not conducive to unblocking after being blocked, and unprocessed scrap iron will be mixed with finished scrap iron after unblocking. For this reason, we propose an anti-blocking scrap iron crushing device.

[0007] The anti-blocking scrap iron crushing device also includes a dredging component, which is transmission-connected to the anti-blocking component to drive the rotating plate to tilt and rotate when the frame moves forward, thereby squeezing the tops of the dynamic crushing roller and the static crushing roller.

A frame plate is fixedly connected to the top of the lifting frame. A threaded column is rotatably connected to one side of the housing. One side of the frame is threadedly connected to the threaded column. A first gear is fixedly connected to one end of the threaded column. A hydraulic rod is fixedly connected to the inside of the housing. An extension block is fixedly connected to the middle of the sliding rod.

[0010] Preferably, the dredging component includes:

[0011] A shaft rod is rotatably connected to the inside of the housing. The bottom of the rotating plate is fixedly connected to the surface of the shaft rod. A second gear is fixedly connected to one end of the shaft rod. A third gear is rotatably connected to the surface of the housing. The second gear is meshed with the third gear.

[0012] Preferably, the protection component includes:

[0013] A buffer plate is slidably connected to the inner wall of the collection box. A plurality of shock-absorbing springs are fixedly connected to the top of the buffer plate. The bottom of the shock-absorbing springs is fixedly connected to the bottom of the inner wall of the collection box.

[0014] Preferably, rollers are rotatably connected to both sides of the sliding rod. Grooves are provided on the surfaces of the rollers. The middle part of the inner wall of the special-shaped sliding groove is in a convex state. The grooves are embedded in the middle part of the inner wall of the special-shaped sliding groove.

[0015] Preferably, limiting grooves are provided on both sides of the frame. The limiting grooves are sleeved on both sides of the static crushing roller.

[0016] Preferably, the frame plate is in a U-shaped structure. The frame plate is sleeved on the surface of the first gear. A toothed groove is provided on one side of the inner wall of the frame plate and is meshed with the first gear.

[0017] Preferably, the bottom of the housing is in a conical structure that gradually narrows from top to bottom. The inner diameter of the collection box is slightly larger than the bottom opening of the housing.

[0019] Technical effects and advantages of the present invention:

[0020] In the present invention, the hydraulic rod drives the sliding rod to move the collection box forward to the bottom of the housing and then rise. During the rising process, the threaded column is driven to rotate, so that the frame moves forward along the middle of the housing, making the moving crushing roller gradually move away from the static crushing roller, discharging the scrap iron blockage stuck between the moving crushing roller and the static crushing roller, and falling into the collection box for storage. Thus, it is convenient to dredge the blocked scrap iron, and at the same time, it avoids the blocked scrap iron directly falling into the processed scrap iron slag, causing the processed scrap iron slag to be mixed with the unprocessed scrap iron.

[0021] In the present invention, the forward movement of the frame drives the rotating plate to deflect, squeezing the blocked scrap iron, improving the dredging effect of the device on the inside of the housing, accelerating the sliding speed of the scrap iron downward from the inside of the housing. At the same time, after the rotating plate rotates to the horizontal state, it is located in the middle of the housing and on top of the moving crushing roller and the static crushing roller, preventing the top of the housing from continuously flowing in scrap iron for crushing, and causing further blockage inside the housing.

[0022] In the present invention, the collection box can be sleeved outside the bottom of the housing. When the scrap iron falls into the collection box, the shock-absorbing spring can effectively absorb the impact force generated when the scrap iron falls, improving the service life of the collection box. At the same time, the reaction force after the shock-absorbing spring is stressed can vibrate the buffer plate to flatten the scrap iron, preventing the scrap iron on the surface of the buffer plate from being blocked at one place inside the collection box, ensuring that the scrap iron can be fully buffered and dispersed when falling into the collection box, and ensuring that the scrap iron will not splash outward after falling.

[0030] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0031] Reference Figures 1 - 6 As shown, the present invention provides a technical solution: an anti-blocking scrap iron crushing device, comprising a shell 1, a shell 3 is fixedly connected to the top of the shell 1, a frame 4 is slidably connected to the bottom of the shell 3, a dynamic crushing roller 5 is installed inside the frame 4, a static crushing roller 6 is installed inside the shell 1, and the anti-blocking scrap iron crushing device also includes a rotating plate 7 and a collecting box 8;

[0032] The bottom of the housing 3 is provided with an anti-blocking component to enable the collection box 8 to move in an L-shaped trajectory and to change the gap between the dynamic crushing roller 5 and the static crushing roller 6 when the collection box 8 moves vertically upward;

[0033] The anti-blocking scrap iron crushing device also includes a dredging component, which is transmission-connected to the anti-blocking component to drive the rotating plate 7 to rotate tiltably when the frame 4 moves forward, and squeeze the top of the dynamic crushing roller 5 and the static crushing roller 6. The device can dredge the blocked scrap iron and prevent the blocked scrap iron from falling directly into the processed scrap iron slag, causing the processed scrap iron slag to be mixed with the unprocessed scrap iron. At the same time, it can squeeze the scrap iron to accelerate the dredging effect and close the top of the shell 3 to prevent the material from entering again.

[0034] Reference Figures 1 - 6 As shown, in this embodiment: the anti-blocking component includes:

[0035] Bracket 9 is fixedly connected to the bottom of the housing 3. On both sides of the inner wall of the bracket 9, special-shaped sliding grooves 10 are provided. Two sliding rods 11 are slidably connected to the inner walls of the special-shaped sliding grooves 10. Connecting rods 12 are rotatably connected to both ends of the sliding rods 11. A rotating rod 13 is rotatably connected to the tops of the two connecting rods 12. The bottom of the collection box 8 is fixedly connected to the top of the rotating rod 13. Cylinders 15 are fixedly connected to both sides of the collection box 8. A lifting frame 16 is fixedly connected to the top of the special-shaped sliding groove 10. A lifting plate 17 is slidably connected to the surface of the cylinder 15. The lifting plate 17 is slidably connected to both ends of the lifting frame 16. A frame plate 18 is fixedly connected to the top of the lifting frame 16. A threaded column 19 is rotatably connected to one side of the housing 3. One side of the frame 4 is threadedly connected to the threaded column 19. A first gear 20 is fixedly connected to one end of the threaded column 19. A hydraulic rod 22 is fixedly connected to the inside of the housing 1. An extension block 23 is fixedly connected to the middle of the sliding rod 11. The output end of the hydraulic rod 22 is fixedly connected to the surface of the extension block 23. When the control computer 2 starts the motor 24 to drive the moving crushing roller 5 to rotate, through the meshing connection of the two transmission teeth 21, the moving crushing roller 5 and the static crushing roller 6 rotate to break the scrap iron. Then, by connecting the control computer 2 with the motor 24, the real-time operating state of the motor 24 is monitored. When the inside of the housing 3 is blocked and affects the normal rotation of the moving crushing roller 5 and the static crushing roller 6, after the operating efficiency of the motor 24 is affected, the control computer 2 will immediately stop the operation of the motor 24, and then start the hydraulic rod 22 to extend, so that the hydraulic rod 22 pushes the extension block 23 to drive the sliding rod 11 to slide forward along the inside of the special-shaped sliding groove 10. And when the sliding rod 11 moves forward, it drives the connecting rod 12 to move forward at the same time, and at the same time makes the collection box 8 move forward. When the collection box 8 moves to directly below the housing 3, it can receive the blocked scrap iron dropped from the housing 3. At this time, when the hydraulic rod 22 continues to move forward, one side of the collection box 8 will abut against the inner wall of the bracket 9, so that the position of the collection box 8 is limited. Then, when the sliding rod 11 moves forward, it will push the two connecting rods 12 to rotate upward, so that the connecting rods 12 are in a vertical state, thereby lifting the height of the collection box 8, so that the collection box 8 is placed at the bottom discharge port of the housing 3. And during the process of driving the collection box 8 to move by the rotation of the connecting rod 12, the cylinder 15 will slide along the inner wall of the lifting plate 17. At the same time, during the process of lifting the collection box 8, the cylinder 15 will drive the lifting plate 17 to move upward along the lifting frame 16 following the upward movement of the collection box 8. At this time, the frame plate 18 will also move upward. Through the meshing connection of the frame plate 18 and the first gear 20, when the frame plate 18 moves upward, it drives the first gear 20 and the threaded column 19 to rotate. When the threaded column 19 rotates, through the meshing connection of the threaded column 19 and the frame 4, the frame 4 will move forward when the threaded column 19 rotates. During the movement of the frame 4, the moving crushing roller 5 and the motor 24 are gradually moved away from the static crushing roller 6, so that the gap between the moving crushing roller 5 and the static crushing roller 6 is enlarged, so that the scrap iron blocked between the moving crushing roller 5 and the static crushing roller 6 can fall downward, achieving the effect of discharging the blockage.To avoid damage to the device caused by material blockage, finally the material falls into the interior of the collection box 8 for storage, and then the staff takes out the unbroken scrap iron and puts it back into the housing 3 for processing, thereby avoiding large unbroken scrap iron directly falling into the processed iron slag due to blockage;

[0036] Among them, the hydraulic rod 22 drives the sliding rod 11 to move the collection box 8 forward to the bottom of the housing 3 and then rise. During the rising process, the threaded column 19 rotates automatically, causing the frame 4 to move forward along the middle of the housing 3, making the moving crushing roller 5 gradually move away from the static crushing roller 6, discharging the scrap iron blockage between the moving crushing roller 5 and the static crushing roller 6, and falling into the collection box 8 for storage. Thus, it is convenient to dredge the blocked scrap iron, and at the same time, it avoids the blocked scrap iron directly falling into the processed iron scraps, resulting in the mixing of the processed iron slag and the unprocessed scrap iron.

[0037] Refer to Figure 2 And Figure 6 As shown, in this implementation plan: The dredging component includes:

[0038] The shaft rod 25 is rotatably connected to the interior of the housing 3. The bottom of the rotating plate 7 is fixedly connected to the surface of the shaft rod 25. One end of the shaft rod 25 is fixedly connected to the second gear 26. The surface of the housing 3 is rotatably connected to the third gear 27. The second gear 26 is meshed with the third gear 27. The surface of the frame 4 is fixedly connected to the toothed groove plate 28. The third gear 27 is meshed with the toothed groove plate 28. When the frame 4 moves forward under the action of the rotation of the threaded column 19, making the moving crushing roller 5 move away from the static crushing roller 6, since the forward movement of the frame 4 will drive the toothed groove plate 28 to move simultaneously, this causes the toothed groove plate 28 to drive the third gear 27 to rotate clockwise. Then, through the meshing connection between the third gear 27 and the second gear 26, the third gear 27 drives the second gear 26 to rotate counterclockwise, causing the shaft rod 25 to drive the rotating plate 7 to deflect through the rotation of the second gear 26. Through the counterclockwise rotation of the rotating plate 7, the rotating plate 7 will gradually rotate into the interior of the housing 3 as the frame 4 moves forward. During the process of the rotating plate 7 rotating to the horizontal state, the blocked scrap iron between the interior of the housing 3, the moving crushing roller 5 and the static crushing roller 6 is squeezed, causing the scrap iron to receive a downward extrusion force, thereby accelerating the downward sliding speed of the scrap iron from the interior of the housing 3 and enhancing the dredging effect on the interior of the housing 3. It avoids excessive accumulation of scrap iron in the housing 3, resulting in jamming again during the sliding process of the scrap iron. At the same time, after the rotating plate 7 rotates to the horizontal state, it is located in the middle of the housing 3 and on top of the moving crushing roller 5 and the static crushing roller 6, preventing the top of the housing 3 from continuing to flow in scrap iron for crushing, thus causing further blockage inside the housing 3.

[0039] Refer to Figure 2 And Figure 4 As shown, in this implementation plan: The protection component includes:

[0040] The buffer plate 29 is slidably connected to the inner wall of the collection box 8. A number of shock-absorbing springs 30 are fixedly connected to the top of the buffer plate 29, and the bottom of the shock-absorbing springs 30 is fixedly connected to the bottom of the inner wall of the collection box 8. The bottom of the housing 3 has a tapered structure that gradually narrows from top to bottom. The inner diameter of the collection box 8 is slightly larger than the bottom opening of the housing 3. When the collection box 8 moves to the bottom of the housing 3 to receive scrap iron, the collection box 8 rises to approach the bottom opening of the housing 3. Then, since the inner diameter of the collection box 8 is larger than the size of the bottom discharge port of the housing 3, the collection box 8 can be sleeved outside the bottom of the housing 3. When the scrap iron falls into the collection box 8, the downward impact force generated by the scrap iron will first hit the buffer plate 29, and then be buffered by the shock-absorbing springs 30. With its good elasticity, the shock-absorbing springs 30 can effectively absorb the impact force generated when the scrap iron falls. At the same time, the reaction force of the shock-absorbing springs 30 after being stressed can vibrate the buffer plate 29 to flatten the scrap iron, preventing the scrap iron on the surface of the buffer plate 29 from being blocked at one place inside the collection box 8, protecting the inner wall of the collection box 8 from hard impact damage. This design not only improves the service life of the collection box 8 but also ensures that the scrap iron can be fully buffered and dispersed when it falls into the collection box 8. Among them, the elasticity of the shock-absorbing springs 30 and the slightly larger design of the inner diameter of the collection box 8 ensure that the scrap iron will not splash outward after falling.

[0041] Refer to Figure 4 and Figure 5 As shown, in this implementation: On both sides of the sliding rod 11, rollers 14 are rotatably connected through bearings. Grooves 31 are provided on the surface of the rollers 14. The middle part of the inner wall of the special-shaped sliding groove 10 is in a convex state, and the grooves 31 are embedded in the middle part of the inner wall of the special-shaped sliding groove 10. Through the rotational connection of the rollers 14 and the sliding rod 11 by bearings, the rotation between the sliding rod 11 and the rollers 14 is smoother. When the hydraulic rod 22 pushes the sliding rod 11 to move, the rollers 14 can rotate on the convex part of the inner wall of the special-shaped sliding groove 10 through the grooves 31, and at the same time slide along the inner diameter of the special-shaped sliding groove 10 on both sides of the rollers 14, thereby restricting the rollers 14 inside the inner wall of the special-shaped sliding groove 10, ensuring that the sliding rod 11 and the rollers 14 move in a straight line, preventing the rollers 14 and the sliding rod 11 from sliding out of the special-shaped sliding groove 10, making the process of the hydraulic rod 22 driving the collection box 8 forward smoother and avoiding separation between structures.

[0042] Refer to Figure 2 and Figure 6As shown in the figure, in this implementation: Limiting grooves 32 are provided on both sides of the frame 4. The limiting grooves 32 are sleeved on both sides of the static crushing roller 6. One end of the frame 4 is embedded inside the housing 3, and the other end is sleeved on the surface of the housing 3. When the frame 4 moves forward, the limiting grooves 32 will move backward along one end of the static crushing roller 6, so that the position of the frame 4 is restricted outside the housing 3, ensuring the horizontal position between the frame 4 and the housing 3. Through the cooperation between the limiting grooves 32 and the static crushing roller 6, it is avoided that the frame 4 is offset or shaken during the movement process.

[0043] Refer to Figure 4 As shown in the figure, in this implementation: The shape of the frame plate 18 is a U-shaped structure. The frame plate 18 is sleeved on the surface of the first gear 20. A tooth groove is provided on one side of the inner wall of the frame plate 18 and is meshed and connected with the first gear 20. Since the frame plate 18 is a U-shaped structure and is sleeved outside the threaded column 19, when the frame plate 18 moves upward to drive the first gear 20 to rotate, since both ends of the frame plate 18 are fixedly connected to the lifting plate 17, the mechanical state of the frame plate 18 is more stable. During the rotation of the first gear 20, the surface of the first gear 20 can slide up and down along the inner wall of the frame plate 18, avoiding deformation of the side with the tooth groove after long-term stress due to unilateral stress on the frame plate 18, improving the structural stability between the frame plate 18 and the first gear 20, ensuring the long-term stable operation of the device, and avoiding misalignment between the frame plate 18 and the first gear 20 after deformation, which affects the transmission effect.

[0044] Working principle: When the control computer 2 starts the motor 24 to drive the moving crushing roller 5 to rotate, through the meshing connection of the two transmission teeth 21, the moving crushing roller 5 and the static crushing roller 6 rotate to break the scrap iron. Then, by connecting the control computer 2 with the motor 24, the real-time operating state of the motor 24 is monitored.

[0045] When the internal blockage of the shell 3 affects the normal rotation of the dynamic crushing roller 5 and the static crushing roller 6, the operating efficiency of the motor 24 is affected, and the control computer 2 will immediately stop the operation of the motor 24, and then start the hydraulic rod 22 to extend, so that the hydraulic rod 22 pushes the extension block 23 to drive the slide bar 11 to slide forward along the inside of the special-shaped slide groove 10, and when the slide bar 11 moves forward, it drives the connecting rod 12 to move forward at the same time, and at the same time makes the collection box 8 move forward. When the collection box 8 moves to the bottom of the shell 3, it can take over the blocked scrap iron dropped by the shell 3. At this time, the hydraulic rod 22 continues to move forward, which will make one side of the collection box 8 against the inner wall of the bracket 9, so that the position of the collection box 8 is limited. After that, the slide bar 11 moves forward to push the two connecting rods 12 to rotate upward, so that the connecting rods 12 are in a vertical state, thereby raising the height of the collection box 8, so that the collection box 8 is placed at the bottom discharge port of the shell 3, and in the process of the collection box 8 moving driven by the rotation of the connecting rod 12 In the process of lifting the collecting box 8, the cylinder 15 will slide along the inner wall of the lifting plate 17. At the same time, when the collecting box 8 is lifted, the cylinder 15 will follow the collecting box 8 to move up and drive the lifting plate 17 to slide upward along the lifting frame 16. At this time, the frame plate 18 will also be in an upward state. The meshing connection between the frame plate 18 and the first gear 20 makes the frame plate 18 drive the first gear 20 and the threaded column 19 to rotate when the frame plate 18 moves up. When the threaded column 19 rotates, the meshing connection between the threaded column 19 and the frame 4 makes the frame 4 move forward when the threaded column 19 rotates. During the movement of the frame 4, the movable crushing roller 5 and the motor 24 gradually move away from the static crushing roller 6, so that the gap between the movable crushing roller 5 and the static crushing roller 6 is expanded, so that the scrap iron blocked between the movable crushing roller 5 and the static crushing roller 6 can fall downward, achieving the effect of discharging the blockage. Finally, the material falls into the collecting box 8 for storage, and the staff takes out the unbroken scrap iron and puts it back into the shell 3 for processing.

[0046] When the frame 4 moves forward under the action of the rotation of the threaded column 19, so that the dynamic crushing roller 5 is away from the static crushing roller 6, the forward movement of the frame 4 will drive the toothed plate 28 to move at the same time, so that the toothed plate 28 drives the third gear 27 to rotate clockwise, and then the third gear 27 is meshed with the second gear 26, so that the third gear 27 drives the second gear 26 to rotate counterclockwise, so that the shaft 25 drives the rotating plate 7 to deflect through the rotation of the second gear 26. Through the counterclockwise rotation of the rotating plate 7, the rotating plate 7 will gradually rotate toward the inside of the shell 3 as the frame 4 moves forward. During the process of the rotating plate 7 rotating to a horizontal state, the blocked scrap iron inside the shell 3 and between the dynamic crushing roller 5 and the static crushing roller 6 is squeezed, so that the scrap iron is subjected to a downward squeezing force, thereby accelerating the downward sliding speed of the scrap iron from the inside of the shell 3, and improving the dredging effect inside the shell 3. At the same time, after the rotating plate 7 rotates to a horizontal state, it is located in the middle position of the shell 3 and is placed on the top of the dynamic crushing roller 5 and the static crushing roller 6, so as to prevent the scrap iron to be crushed from flowing into the shell 3 again after being blocked.

[0047]

[0047] When the collection box 8 moves to the bottom of the housing 3 to receive scrap iron, it is moved upward to approach the bottom opening of the housing 3. Then, since the inner diameter of the collection box 8 is larger than the size of the bottom discharge port of the housing 3, the collection box 8 can be sleeved outside the bottom of the housing 3. When the scrap iron falls into the interior of the collection box 8, the downward impact force generated by the scrap iron will first impact the buffer plate 29, and then be buffered by the shock-absorbing spring 30. With its good elasticity, the shock-absorbing spring 30 can effectively absorb the impact force generated when the scrap iron falls. At the same time, the reaction force of the shock-absorbing spring 30 after being stressed can vibrate the buffer plate 29 to level the scrap iron, preventing the scrap iron on the surface of the buffer plate 29 from being blocked at one place inside the collection box 8, protecting the inner wall of the collection box 8 from hard impact damage, and ensuring that the scrap iron does not splash outward after falling.

[0048] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
