Description

Technical Field

[0001] This application relates to the technical field of recycling of renewable resources, and in particular to a system for dismantling and recycling metals from scrapped vehicles. Background Technology

[0002] Metal recycling refers to the process of separating useful materials from scrap metal and then physically or mechanically processing them into reusable products. It's a complete industrial chain from collection and dismantling to reuse. The metal recycling industry has formed a complete industrial chain and recycling ecosystem. Besides its environmental impact, metal mining and smelting consume 7% to 8% of global energy supply. Recycling metals consumes less energy than primary metal production and reduces the overall impact on mining sites. Metal recycling can also reduce the demand for low-grade ores and avoid the mining of some scarce precious metals in the future. Theoretically, metals can be recycled almost indefinitely. Therefore, metal recycling presents a significant opportunity for environmental protection, energy and water utilization, and contributes to the transition to a low-carbon, resource-saving green economy. Plastic recycling refers to the process of recycling waste plastics using specific recycling technologies to achieve the goal of turning waste into treasure. With the continuous increase in the consumption of plastic products, the amount of waste plastic is also increasing. In addition, my country's annual consumption of plastics for automobiles has reached 400,000 tons, and these products become one of the important sources of waste plastics after they are scrapped.

[0003] For example, Chinese Patent CN107775846A discloses a waste plastic recycling device, including a crushing chamber with a feed inlet at its upper end and a crushing roller inside. The lower end of the crushing chamber is connected to the upper end of a separation chamber via a first pipe. A movable plate of the same size and parallel to the bottom surface of the separation chamber is installed inside the separation chamber. A support frame is connected to the lower end of the separation chamber, and the lower end of the movable plate is connected to a telescopic head of a telescopic cylinder. The side wall of the separation chamber, located above the movable plate, is connected to a melting chamber via a second pipe. A heating layer is installed inside the melting chamber, which is connected to a cooling chamber via a third pipe. This invention can effectively remove metallic impurities mixed in waste plastics, which is beneficial for plastic molding and recycling.

[0004] However, the above-mentioned existing technology has the following technical defects: First, the waste plastic enters the crushing chamber and is crushed by the crushing rollers in the crushing chamber. Then it enters the separation chamber, where the movable plate shakes up and down under the action of the telescopic cylinder. Since the density of metal impurities is much higher than that of plastic fragments, after this process, the high-density metal impurities will remain at the bottom. At the same time, the dust generated by the shaking is removed by the action of the induced draft fan. After the plastic fragments enter the melting chamber under the action of the feeding rollers, the magnetic layer on the feeding rollers can further attract the magnetic metal. Finally, the plastic fragments reach the cooling chamber and are cut and recycled. The crushed waste plastic is separated in the separation chamber by a moving plate and a magnetic layer on the feed roller. Since the feed roller is located at the inlet of the second pipe, and the magnetic layer is located on the scraper of the feed roller, the spacing between the scrapers is very small, and the space in the second pipe is also relatively narrow. Therefore, after prolonged operation, a large amount of magnetic metal easily adheres to the scrapers, causing blockage at the inlet of the second pipe. This makes it difficult for plastic fragments to enter the melting chamber, thus affecting the operation of the entire device. To avoid this, manual cleaning of the magnetic metal adsorbed on the scrapers is required periodically. However, cleaning requires shutting down the device and removing the scrapers, which is extremely inconvenient. Therefore, based on the existing waste plastic recycling device, there is still room for improvement to overcome the aforementioned technical shortcomings. Summary of the Invention

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. In order to facilitate the collection and recycling of materials after the dismantling of scrapped vehicles, a separation device is provided in this application. The scrapped vehicle after being squeezed is placed into the dismantling box, and the scrapped vehicle is dismantled by the dismantling box. The dismantled fragments fall into the separation device set below. The adsorption plate will cooperate with the feeding mechanism to adsorb metal materials on the adsorption plate and plastic materials will fall into the trapezoidal box. Then, by controlling the feeding mechanism, the metal materials adsorbed on the adsorption plate can be put into the metal box, thereby achieving the effect of separating metal materials from plastic materials.

[0019] 2. Since some small metal materials may fall into the trapezoidal box along with the plastic materials, resulting in incomplete separation of the metal and plastic materials, this application includes a collection device to further separate the metal materials mixed with the plastic materials. The plastic and metal materials falling into the trapezoidal box will fall into the water tank of the collection device through the inclined surface of the trapezoidal box. The metal materials will be attracted by the magnetic ring installed in the water tank, while the plastic materials will float in the water due to buoyancy. Then, the drive mechanism drives the rejection ring to push the metal materials on the magnetic ring into the metal collection box, thereby achieving the effect of secondary separation of the metal materials mixed with the plastic materials.

[0020] 3. In order to collect the plastic fragments floating in the water storage tank, the collection device is also equipped with a pushing mechanism and a plastic collection mechanism. First, the driving mechanism and the pushing mechanism work together to push the plastic fragments floating in the water storage tank toward the plastic collection box in the plastic collection mechanism, so that the plastic fragments floating in the water storage tank float and gather above the plastic collection box. Then, the driving mechanism and the pushing mechanism work together to collect the plastic fragments floating and gathering above the plastic collection box into the plastic collection box.

[0032] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0033] This application discloses a scrapped vehicle dismantling and metal recycling system. Its main function is to enable long-term recycling of recyclable resources without being limited by the device itself or requiring periodic cleaning. Specifically, the metal recycling system includes two fixed frames 1, a trapezoidal plate 11, an indicator plate 12, and a support frame 13 located between the fixed frames 1 and the trapezoidal plate 11. Two T-shaped rods 14 are installed on the two fixed frames 1. A dismantling box 15 for dismantling the vehicle is fixed between the two T-shaped rods 14. A separation device 2 for separating metal and plastic is located between the two fixed frames 1. A collection device 3 for screening and collecting the separated plastic is installed on the support frame 13. First, the scrapped vehicle to be dismantled is placed into the dismantling box 15. The dismantling rollers in the dismantling box 15 shred the vehicle. The shredded material is discharged downwards through the outlet at the bottom of the dismantling box 15. During the discharge process, the metal and plastic materials in the shredded material are separated by the separation device 2, and then further separated by the collection device 3 before being collected and processed centrally.

[0034] Reference Figure 1 and Figure 2 As shown, since the fragmented metal and plastic materials of scrapped cars are mixed together after dismantling, a separation device 2 is provided in this application to facilitate targeted recycling. The separation device 2 includes a metal box 21, an adsorption plate 22, a trapezoidal box 23, a long plate 24, a synchronization mechanism 4, and a feeding mechanism 5. The metal box 21 is fixedly installed between two fixed frames 1. The adsorption plate 22 is symmetrically rotated and located at the lower outlet of the dismantling box 15. It can limit the fragments of the dismantled car discharged from the outlet of the dismantling box 15 and adsorb the metal fragments therein, so that they do not fall downwards but are attached to the two adsorption plates 22. The trapezoidal box 23 is fixedly installed inside the metal box 21 located below the dismantling box 15, and one end penetrates the metal box 21. Extending outward, the trapezoidal box 23 has an inclined surface inside. After the car fragments fall into the trapezoidal box 23, they can slide out of the metal box 21 through the inclined surface inside the trapezoidal box 23. The upper end of the trapezoidal box 23 has an opening that can be used to receive the car fragments falling from the dismantling box 15. Two triangular plates are set on both sides of the opening to prevent the car fragments from falling out from the side.

[0035] The long plate 24 is symmetrically rotated and installed at the upper opening of the trapezoidal box 23. When subjected to force, the long plate 24 can tilt towards each other and eventually come into contact with the two triangular plates. The adsorption plate 22 and the long plate 24 are initially in a "Y" shape, forming a "Y" shaped falling area. Plastic fragments fall into the trapezoidal box 23 through the "Y" shaped falling area. The synchronization mechanism 4 is located inside the metal box 21 and can synchronously control the position of the adsorption plate 22 and the long plate 24. The feeding mechanism 5 is located on the adsorption plate 22 and the metal box 21 and can control the feeding of the separated metal.

[0036] When the dismantled car fragments are discharged from the dismantling box 15, the metal fragments will be adsorbed onto the adsorption plate 22 due to the action of the adsorption plate 22 and the feeding mechanism 5, while the other plastic fragments will fall into the trapezoidal box 23 through the "Y"-shaped drop area. When there are a lot of metal fragments adsorbed on the adsorption plate 22 or when the dismantling of a scrapped car is completed and the dismantling of the car is stopped, the synchronization mechanism 4 and the feeding mechanism 5 can be activated to put the metal fragments adsorbed on the adsorption plate 22 into the metal box 21, thereby achieving the effect of separating metal fragments and plastic fragments. When the metal box 21 stores a certain amount of metal fragments, the opening at the bottom of the metal box 21 can be opened, and the metal fragments will fall into the collection vehicle parked on the indicator plate 12 through the opening at the bottom of the metal box 21.

[0037] Reference Figure 3 and Figure 4As shown, in order to synchronously drive the long plate 24 to adjust its position when adjusting the position of the adsorption plate 22, a synchronization mechanism 4 is installed in the separation device 2. The synchronization mechanism 4 includes a lead screw 41, a short slider 42, a long slider 43, a connecting column 44, a spring rod 45, a pulling bar 46, and a drive motor 47. The lead screw 41 is rotatably installed in the metal box 21. The lead screw 41 is composed of two short lead screws, which are symmetrically arranged in the metal box 21 and are fixedly connected together. Driving one short lead screw to rotate will cause the other short lead screw to rotate synchronously. The short slider 42... The long slider 43 is symmetrically slidably mounted on the lead screw 41 between the two short sliders 42. The connecting post 44 is respectively located between the long slider 43 and the adsorption plate 22. One end is fixedly connected to the long slider 43, and the other end is slidably inserted into the adsorption plate 22. The adsorption plate 22 has a sliding groove 221 for the connecting post 44 to slide into. Rotating the lead screw 41 can simultaneously drive the two long sliders 43 to move away from each other in a square direction. Due to the action of the connecting post 44, the two adsorption plates 22 will be synchronously driven to rotate away from each other. During the movement, they will respectively abut against the two short sliders 42, driving the two short sliders 42 to also move away from each other in a square direction.

[0038] Spring rods 45 are symmetrically fixed on the inner wall of metal box 21, and the telescopic ends of the two spring rods 45 respectively abut against the two short sliders 42. When the long slider 43 moves back to its initial position and does not abut against the short slider 42, the short slider 42 will also move back to its initial position due to the pushing force of the spring rods 45. It should be noted that the abutting force of the long slider 43 against the short slider 42 is greater than the pushing force of the spring rods 45 against the short slider 42. The two pull bars 46 are stacked in a cross shape and rotated on the two long plates 24. The other end is rotatably connected to the short slider 42. The pull bars 46 are driven by the short slider 42 and can drive the two long plates 24 to rotate closer or further apart. The drive motor 47 is fixed on the outer wall of metal box 21 through the short support plate 16, and the rotating end extends inward through the side wall of metal box 21 and is fixedly connected to the lead screw 41.

[0039] When there are too many metal fragments attached to the adsorption plate 22, or when the dismantling box 15 stops dismantling after a scrapped car has been dismantled, the drive motor 47 is started to drive the lead screw 41 to rotate. Due to the rotation of the lead screw 41, the two long sliders 43 on the lead screw 41 slide simultaneously away from each other. Since the long sliders 43 and the adsorption plate 22 are connected by the connecting column 44... When the two long sliders 43 slide, they simultaneously drive the adsorption plates 22 to expand outward, that is, to rotate away from each other. After sliding a certain distance, the two long sliders 43 will come into contact with the two short sliders 42, driving the two short sliders 42 to also slide away from each other. The pull bar 46 connects the short sliders 42 and the long plates 24 together. Therefore, when the two short sliders 42 slide away from each other, they can simultaneously drive the two long plates 24 to move closer to each other until the two long plates 24 come into contact with the triangular plate, forming the effect of closing the opening at the top of the trapezoidal box 23. At this time, the two adsorption plates 22 are in an outward tilted and open state. The two adsorption plates 22 and the two long plates 24 form a new area for metal fragments to fall.

[0040] Finally, the feeding mechanism 5 is activated. The metal fragments that were originally adsorbed on the adsorption plate 22 will fall into the metal box 21 through the newly formed fragment dropping area. Since the long plate 24 has closed the upper opening of the trapezoidal box 23 at this time, the metal fragments will not fall into the trapezoidal box 23 but only into the metal box 21. After the feeding is completed, the drive motor 47 is activated to drive the lead screw 41 to reverse so as to drive the long slider 43 to return to the initial position. At the same time, the short slider 42 will also return to the initial position due to the pushing force of the spring rod 45. At this time, the adsorption plate 22 and the long plate 24 will also be driven to return to the initial position due to the return sliding of the long slider 43 and the short slider 42.

[0041] Reference Figure 5 and Figure 6 As shown, since it is necessary to put the metal fragments attached to the adsorption plate 22 into the metal box 21, a feeding mechanism 5 is also installed in the separation device 2. The feeding mechanism 5 includes a magnetic block 51, a transmission block 52, a long support plate 53, a cylinder 54, an insertion plate 55, a pulling rod 56, and a pulling block 57. The magnetic block 51 is slidably inserted into the adsorption plate 22. The side of the adsorption plate 22 away from the sliding groove 221 has an insertion groove 222 for the magnetic block 51 to slide. The reason why the metal fragments can be attracted by the adsorption plate 22 is that the adsorption plate 22 has a magnetic block 51. The magnetic block 51 can attract the metal fragments that fall from the disassembly box 15 onto the adsorption plate 22. The transmission block 52 is fixedly installed at one end of the magnetic block 51. The transmission block 52 is composed of a long block and two short blocks. The two short blocks are arranged parallel to each other on the long block, and a snap-fit ​​area is formed between the two short blocks.

[0042] A long support plate 53 is fixedly installed on the outer wall of the metal box 21. A cylinder 54 is fixedly installed on the long support plate 53. An insertion plate 55 is slidably inserted into the side wall of the metal box 21 away from the cylinder 54. The metal box 21 has a long slot for the insertion plate 55 to slide in. A pulling rod 56 is fixedly installed on the extension end of the cylinder 54 and the insertion plate 55. When the cylinder 54 drives the pulling rod 56 to move, the insertion plate 55 will also move along with it. At the same time, the insertion plate 55 also plays a role in parallel stabilization of the pulling rod 56. A pulling block 57 is symmetrically fixed on the side of the pulling rod 56 facing the magnetic block 51 and can be engaged with the transmission block 52. The pulling block 57 is L-shaped. When the adsorption plate 22 rotates outward to expand, one end of the pulling block 57 can be engaged with the transmission block 52. Within the snap-fit ​​area, the pull block 57 can drive the transmission block 52 to move, which in turn drives the magnetic block 51 to slide; an extension slot 17 for the magnetic block 51 to extend is provided on the side wall of the metal box 21 below the pull block 57.

[0043] Driven by the drive motor 47, the two adsorption plates 22 expand outwards. When the two long plates 24 rotate towards each other and abut against the opening at the top of the closed trapezoidal box 23, the transmission block 52 and the pulling block 57 are in a locked state. The pulling block 57 can drive the transmission block 52, and the start cylinder 54 drives the pulling rod 56 to move away from the metal box 21. The magnetic block 51 will also slide outwards from the adsorption plate 22 through the extension slot 17 on the metal box 21, thereby driving the magnetic block 51 to pull out the adsorption plate 22. When the cylinder 54 extends to the maximum extension distance, the magnetic block 51 is completely pulled out of the adsorption plate 22, leaving only a part inside the adsorption plate 22, which is convenient for subsequent stable re-insertion into the adsorption plate 22. At this time, the adsorption plate 22 no longer has the attraction force for metal. The metal fragments originally attached to the adsorption plate 22 will fall into the metal box 21, achieving the effect of unloading metal fragments. After unloading, the cylinder 54 retracts and resets, driving the magnetic block 51 to re-insert into the adsorption plate 22. The drive motor 47 The drive screw 41 reverses to drive the adsorption plate 22 to rotate inward to return to the initial state, and the long plate 24 rotates outward to the vertical state, that is, to return to the initial state.

[0044] Reference Figure 7As shown, in order to perform secondary separation and collection of fragments falling into the trapezoidal box 23, a collection device 3 is installed on the support frame 13. The collection device 3 includes a water tank 31, a partition plate 32, a fixed roller 33, a magnetic ring 34, a rejection ring 35, a metal receiving box 36, a drive mechanism 6, a push mechanism 7, and a plastic collection mechanism 8. The water tank 31 is fixedly installed on the support frame 13 and located below the extended end of the trapezoidal box 23. The water tank 31 is used to receive car fragments that slide down from the trapezoidal box 23. The partition plate 32 is fixedly installed inside the water tank 31 and divides the water tank 31 into a receiving area 311 and a storage area 312. The fixed roller 33 is fixedly installed inside the receiving area 311 of the water tank 31. The magnetic ring 34 is fixedly sleeved on the fixed roller 33. The rejection ring 35 is rotatably sleeved on the magnetic ring 34.

[0045] The fragments that slide down from the trapezoidal box 23 will fall into the receiving area 311. Among them, the smaller metal fragments mixed with the plastic fragments will be attracted to the magnetic ring 34. When the rejection ring 35 is driven to rotate, it can slowly push the metal fragments attached to the magnetic ring 34 to the storage area 312, while the plastic fragments float on the receiving area 311 due to the buoyancy of the water in the water tank 31. The metal receiving box 36 is slidably disposed at the lower end of the water tank 31 and located below the storage area 312. The storage area 312 and the metal receiving box 36 are interconnected. The driving mechanism 6 is disposed on the outer wall of the water tank 31 and can drive the rejection ring 35. The pushing mechanism 7 is disposed on the water tank 31 and is driven by the driving mechanism 6. The plastic collection mechanism 8 is installed on the outer wall of the water tank 31 away from the driving mechanism 6.

[0046] The fragments sliding down from the trapezoidal box 23 first fall into the receiving area 311 of the water tank 31. The plastic fragments float on the water surface of the receiving area 311 due to buoyancy, while the metal fragments mixed with the plastic fragments sink. Then, they are attracted by the magnetic ring 34 due to the attraction. At this time, the metal fragments will adhere to the magnetic ring 34. The drive mechanism 6 drives the rejection ring 35 to rotate on the magnetic ring 34. The rejection ring 35 can slowly push the metal fragments attached to the magnetic ring 34 from the receiving area 311 to the storage area 312. The metal fragments entering the storage area 312 will fall into the metal collection box 36. At this point, the separation of the car fragments is completed. Then, the drive mechanism 6 drives the pushing mechanism 7 to push the plastic fragments floating on the receiving area 311 to the plastic collection mechanism 8 for centralized collection and processing.

[0047] Reference Figure 7 and Figure 8As shown, since secondary separation of plastic fragments and metal scraps is required, a drive mechanism 6 is provided in the collection device 3. The drive mechanism 6 includes a support block 61, a rotating motor 62, a transmission disc 63, and a connecting bar 64. The support block 61 is fixedly installed on the outer wall of the water storage tank 31. The rotating motor 62 is fixedly installed on the support block 61, and its rotating end extends inward through the water storage tank 31. The transmission disc 63 is fixedly installed on the extended end of the rotating motor 62. The connecting bar 64 is fixedly installed on the transmission disc 63 and the rejection ring 35, with one end connected to the transmission disc 63. One end is fixedly connected to the other end, and the other end is fixedly connected to the rejection ring 35. When the rotating motor 62 is turned on, the transmission disk 63 is driven to rotate. Since the connecting strip 64 connects the transmission disk 63 and the rejection ring 35 together, the rotation of the transmission disk 63 can drive the rejection ring 35 to rotate on the magnetic ring 34. When the rejection ring 35 rotates, it can push the metal fragments attached to the magnetic ring 34 from the receiving area 311 to the storage area 312. Finally, the metal fragments will fall into the metal collection box 36 to achieve the effect of centralized collection of metal fragments after secondary separation.

[0048] Reference Figure 7 and Figure 8 As shown, in order to push the plastic fragments floating on the receiving area 311 away from the storage area 312 and separate the metal fragments from the plastic fragments, a pushing mechanism 7 is installed on the collecting device 3. The pushing mechanism 7 includes a support rod 71, a double-acting screw 72, a transmission belt 73, a rectangular slider 74, a fixed column 75, a push plate 76, a reset rod 77, a reset guide block 78, and an inclined guide block 79. The support rod 71 is symmetrically fixed on the outer wall of the water storage tank 31 on the side away from the metal box 21. The double-acting screw 72 is rotatably mounted on the two support rods 71, and the double-acting screw 72 near the end of the rotating motor 62 extends through the support rod 71 toward the rotating motor 62. The transmission belt 73 is sleeved on the rotating rod of the rotating motor 62 and the extension end of the double-acting screw 72 located outside the water storage tank 31. Due to the action of the transmission belt 73, the rotating motor 62 can drive the double-acting screw 72 to rotate synchronously when it rotates.

[0049] A rectangular slider 74 is slidably mounted on a bidirectional lead screw 72. A fixed post 75 is rotatably mounted on the side of the rectangular slider 74 facing the water tank 31. A push plate 76 is fixedly mounted on the end of the fixed post 75 away from the rectangular slider 74, and the push plate 76 is located within the receiving area 311. When the bidirectional lead screw 72 is rotated by the rotating motor 62, it can drive the push plate 76 to slide back and forth in the receiving area 311. When the push plate 76 slides away from the partition plate 32, it can simultaneously push the plastic fragments floating on the water surface of the receiving area 311 away from the partition plate 32. A reset rod 77 is fixedly mounted on the fixed post 75 located between the rectangular slider 74 and the water tank 31. A reset guide block 78 is fixedly mounted on the outer side of the water tank 31 facing the rectangular slider 74. On the side wall, the inclined guide block 79 is fixedly installed on the inner side wall of the water storage tank 31 and is located in the receiving area 311 away from the partition plate 32. When the push plate 76 moves away from the partition plate 32, it will eventually come into contact with the inclined guide block 79. Due to the inclined surface of the inclined guide block 79, when the two come into contact, the contact force will drive the push plate 76 to rotate clockwise and eventually be parallel to the water storage tank 31. The reset rod 77 will change from the original horizontal state to the vertical state. In this way, when the push plate 76 moves towards the partition plate 32 to reset, it will not come into contact with the water in the water storage tank 31, that is, it will not push the plastic fragments that fall and float on the water surface towards the partition plate 32. This ensures that the push plate 76 can only push the floating plastic fragments away from the partition plate 32.

[0050] Then, as the push plate 76 approaches its initial position near the partition plate 32, the vertical reset rod 77 contacts the reset guide block 78. Similarly, the inclined surface of the reset guide block 78 causes the push plate 76 to rotate counterclockwise and return to its initial vertical position, while the reset rod 77 changes from a vertical to a horizontal position. This process repeats, allowing the push plate 76 to push away plastic fragments floating on the water surface when it moves away from the partition plate 32. When the push plate 76 moves from a position away from the partition plate 32 towards the partition plate 32, it remains horizontal and does not come into contact with the water surface, meaning it will not push floating debris. When it gets close to the partition plate 32, it returns to its initial state. It should be noted that the push plate 76 is rotatably mounted on the rectangular slider 74 via the fixed column 75, and it has a large damping effect. When the push plate 76 moves away from the partition plate 32 and comes into contact with the water in the water tank 31 and the floating plastic debris, the large damping prevents the push plate 76 from rotating. Only when the push plate 76 contacts the inclined guide block 79 or the reset rod 77 contacts the reset guide block 78 will the push plate 76 rotate clockwise and counterclockwise. While pushing the plastic debris, the push plate 76 also has a certain cleaning effect on the floating plastic debris.

[0051] Reference Figure 9As shown, since it is necessary to collect and process the plastic fragments floating on the water surface, a plastic collection mechanism 8 is also provided in the collection device 3. The plastic collection mechanism 8 includes a container 81, a plastic collection box 82, a rectangular plate 83, and a driver 9. The container 81 is fixedly installed on the outer wall of the water storage tank 31 on the side away from the rotating motor 62, and both the container 81 and the water storage tank 31 have rectangular holes 811 to connect them. The plastic collection box 82 is slidably disposed in the container 81, and the plastic collection box 82 has many water passage holes. The rectangular plate 83 is fixedly installed on the outer wall of the container 81 on the side away from the water storage tank 31. The driver 9 is disposed on the container 81 and the rectangular plate 83. The push plate 76 pushes the plastic fragments floating on the water surface to move away from the partition plate 32, that is, towards the plastic collection box 82. When it is about to approach the plastic collection box 82, the rectangular slider 74 will cooperate with the driver 9 to drive the plastic collection box 82 downward, that is, towards the container 81. When the pusher plate 76 slides inward, the plastic fragments pushed by the pusher plate 76 will enter the plastic collection box 82. When the pusher plate 76 is driven away from the plastic collection box 82 by the rectangular slider 74, the driver 9 will drive the plastic collection box 82 to move upward, that is, return to the initial position. At the same time, the plastic fragments that were originally above the plastic collection box 82 will enter the plastic collection box 82, achieving the effect of centralized collection of plastic fragments.

[0052] Reference Figure 9 and Figure 10As shown, in order to drive the plastic collection box 82 to move up and down, a driver 9 is provided in the plastic collection mechanism 8. The driver 9 includes a shrink block 91, an L-shaped rod 92, a push spring 93, a pressure rod 94, and a push rod 95. The shrink block 91 is fixedly mounted on the rectangular plate 83, and the L-shaped rod 92 is slidably mounted on the shrink block 91. One end of the L-shaped rod 92 bends and extends towards the upper end of the plastic collection box 82 and is fixedly connected to the upper end of the plastic collection box 82. The shrink block 91 has a hole for the L-shaped rod 95. 2. A rectangular groove 911 that slides up and down; an L-shaped rod 92, when driven, can drive the plastic collection box 82 to move up and down within the housing box 81; a push spring 93 is located within the rectangular groove 911, one end of which abuts against the bottom end of the rectangular groove 911, and the other end of which abuts against the L-shaped rod 92 sliding within the rectangular groove 911; a pressure rod 94, one end of which is rotatably mounted on the outer wall of the housing box 81 facing the shrink block 91, and the other end extending obliquely upward through the L-shaped rod 92; the L-shaped rod 92 is provided with a pressure rod 94. Through the through hole 921, the push rod 95 is slidably mounted on the support rod 71 near the housing 81, with one end abutting against the inclined surface of the pressure rod 94. The end facing the rectangular slider 74 can abut against it when the rectangular slider 74 moves towards the plastic collection box 82. Since the other end of the push rod 95 abuts against the inclined surface of the pressure rod 94, when the rectangular slider 74 abuts against the push rod 95 and pushes the push rod 95 towards the plastic collection box 82, it can drive the plastic collection box 82 to slide downward. The support rod 71 is provided with a sliding hole 711 for the push rod 95 to slide.

[0053] The bidirectional lead screw 72 rotates, driving the rectangular slider 74 to move a certain distance toward the plastic collection box 82. It then contacts the push rod 95, causing the push rod 95 to move toward the L-shaped rod 92. Since one end of the push rod 95 contacts the inclined surface of the pressure rod 94, the push rod 95 presses down on the L-shaped rod 92 through the pressure rod 94. The downward movement of the L-shaped rod 92 simultaneously drives the plastic collection box 82 downward. While the rectangular slider 74 pushes the push rod 95 to move the plastic collection box 82 downward, the rectangular slider 74 also pushes the floating plastic fragments into the plastic collection box 82 via the push plate 76. When the rectangular slider 74 moves away from the plastic collection box 82 toward the partition plate 32, the push rod 95... When the rectangular slider 74 is no longer pushed, the push spring 93 will push the L-shaped rod 92 upward to reset. As the L-shaped rod 92 moves upward to return to its initial position, it will drive the pressure rod 94 and the push rod 95 to reset. The plastic collection box 82 moves upward to return to its initial position, collecting the plastic fragments pushed by the push plate 76 into the plastic collection box 82, so as to achieve the effect of centralized collection of plastic fragments.

[0054] Looking back Figure 5As shown, since the metal fragments are attached to the adsorption plate 22 by the magnetic attraction of the magnetic block 51, some metal fragments will also move out of the metal box 21 when the magnetic block 51 is pulled out of the adsorption plate 22. In order to avoid this situation and allow the metal fragments to fall completely into the metal box 21, a baffle 223 is fixedly installed on the side of the adsorption plate 22 that is close to the magnetic block 51 and extends outward. When the magnetic block 51 is pulled out, the baffle 223 can completely block the metal fragments from moving out of the metal box 21.

[0055] The implementation principle of this embodiment is as follows:

[0056] (1) Shredding and separation: First, the scrapped car is placed in the dismantling box 15 for shredding. The shredded car fragments fall into the separation device 2. The separation device 2 is used to achieve the first separation operation of metal fragments and plastic fragments in the car fragments.

[0057] (2) Secondary separation: Some of the smaller metal fragments mixed in with the plastic fragments are not adsorbed by the adsorption plate 22 and will fall into the trapezoidal box 23 along with the plastic fragments. Then, they slide from the trapezoidal box 23 into the collection device 3. The drive mechanism 6 in the collection device 3 drives the rejection ring 35 to rotate, which can push the metal fragments adsorbed on the magnetic ring 34 to the metal collection box 36 for secondary separation.

[0058] (3) Centralized collection: The plastic fragments that fall into the collection device 3 will float in the water storage tank 31 due to buoyancy. The driving mechanism 6 in the collection device 3 drives the pushing mechanism 7 to push the plastic fragments floating on the water surface to the plastic collection box 82. Finally, the driver 9 and the plastic collection box 82 are used to collect the plastic fragments in a centralized manner.

Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
