[0009] Preferably, the contact assembly includes a sliding groove, the sliding groove is opened on the side of the rotating rod, the inner side of the sliding groove is fixedly connected with a fixed block, the side of the fixed block is slidably connected with a sliding rod, the end of the sliding rod away from the fixed block is fixedly connected with a cleaning plate, the side of the cleaning plate is slidably connected to the inner side of the sliding groove, the side of the cleaning plate is opened with a square groove, a second spring is sleeved on the sliding rod, one end of the second spring is fixedly connected to the cleaning plate, and the other end of the second spring is fixedly connected to the fixed block; when the asphalt concrete waste continues to enter the feeding barrel, the asphalt concrete waste is connected to the rotating rod to maintain The impact is continuously performed, so that the rotating rod rotates on the fixed plate through the electric rotating shaft, and at the same time, the rotating rod collides with the asphalt concrete waste that continuously enters the feeding barrel, so that the asphalt concrete waste can enter the feeding barrel evenly. When the rotating rod rotates, the cleaning plate slides in the sliding groove through the sliding rod through the centrifugal force, so that the cleaning plate can contact and rotate with the inner wall of the feeding barrel. Since the asphalt concrete waste itself is sticky, it is avoided that part of the asphalt concrete waste will be attached to the inner side of the feeding barrel during feeding, thereby interfering with the spraying dust reduction work and crushing work;

[0010] Preferably, the screening mechanism comprises a screen plate, the side surface of the screen plate is slidably connected to the inner side of the crushing box, both sides of the crushing box are fixedly connected with a motor, the output end of the motor is fixedly connected to the top of the screen plate, the inner side of the crushing box is fixedly connected with a connecting frame, the connecting frame is arranged on the bottom of the screen plate, and the top of the connecting frame is fixedly connected with an ejection assembly; when the asphalt concrete waste crushed by the crushing roller falls on the screen plate, the motor is turned on and the screen plate is driven to move up and down in the inner cavity of the crushing box by the output end of the motor, so as to screen the crushed asphalt concrete waste; when the output end of the motor drives the screen plate to move downward, when the screen plate contacts the ejection assembly, the ejection assembly cleans and ejects the mesh of the screen plate, so as to avoid clogging of the mesh on the screen plate when the crushed asphalt concrete waste is screened, thereby interfering with the screening work;

If it is not cleaned for a long time, a large amount of asphalt residue will accumulate on the inner wall of the mesh, which will interfere with the screening work. At the same time, the contact plate is made of hard plastic material. When the screen plate and the contact plate are released from extrusion contact, the contact plate can rebound elastically through its own elasticity. After the contact plate cleans the inner side of the mesh, the asphalt impurities attached to itself will be bounced off. When the asphalt impurities blocked in the mesh are stuck tightly between the inner wall of the mesh, the extrusion force of the ejector pin and the impurities during ejection and extrusion is greater than the tensile force of the third spring, the ejector pin moves downward through the slide bar, and the slider drives the slide bar to move in the notch. At the same time, the buffering work of the third spring is used to avoid the phenomenon that the extrusion force between the ejector pin and the impurities is too large, which will cause extrusion damage to the ejector pin.

[0012] Preferably, the discharging mechanism includes a discharging shell, the top of the discharging shell is fixedly connected to the bottom of the crushing box, the bottom of the discharging shell is provided with a discharging port, the bottom of the inner cavity of the discharging shell is fixedly connected to a first telescopic rod, the top of the first telescopic rod is fixedly connected to an extrusion frame, a fifth spring is sleeved on the first telescopic rod, the top of the fifth spring is fixedly connected to the extrusion frame, the bottom of the fifth spring is fixedly connected to the bottom of the inner cavity of the discharging shell, a connecting shaft is slidably connected to the side of the extrusion frame, a scraper assembly is fixedly connected to the end of the connecting shaft away from the extrusion frame, and a sixth spring is sleeved on the connecting shaft , one end of the sixth spring is fixedly connected to the extrusion frame; when the screened asphalt concrete waste continues to fall into the discharge shell and is discharged through the discharge port, when a large amount of asphalt concrete waste is extruded and impacted by the extrusion frame, the extrusion frame can be driven to move downward through the first telescopic rod, so that the extrusion frame drives the scraper assembly to clean the inner side of the discharge shell, thereby avoiding the heat generated when the crushing roller extrudes and crushes the asphalt concrete waste, causing part of the asphalt in the asphalt concrete waste to melt, so that it will adhere to the inner side of the discharge shell during discharge, making it difficult to fall naturally;

[0013] Preferably, the scraper assembly includes a connecting rod, one end of the connecting rod is fixedly connected to the connecting shaft, and the other end of the connecting rod is fixedly connected to a square plate member, and the square plate member is composed of two plates, one long and one short, and the scrapers are slidably connected to the long plate of the square plate member on both sides, and the scraper is fixedly connected to a connecting sleeve on the side of the scraper away from the square plate member, and the second telescopic rod is fixedly connected to the side of the connecting sleeve at one end of the second telescopic rod away from the short plate of the square plate member.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention sets a feeding mechanism and turns on the driving motor at the bottom of the electric shaft, so that the output end of the driving motor at the bottom of the electric shaft drives the electric shaft to rotate on the fixed plate, so that the rotating rod rotates on the fixed plate through the electric shaft, and when the rotating rod rotates, the rotating rod and the extrusion plate are squeezed, and the extrusion plate drives the arc plate to move in the water tank through the extrusion rod, so that the arc plate squeezes the water stored in the water tank and sprays the water stored in the water tank through the spray head, so that when the asphalt concrete waste is continuously fed, the water mist sprayed by the spray head can be used to spray and reduce dust around the feeding barrel, thereby avoiding the phenomenon of dust floating when the asphalt concrete waste is continuously discharged.

[0016] 2. The present invention sets a contact component. When the asphalt concrete waste continuously enters the feed barrel, the asphalt concrete waste continuously impacts the rotating rod, so that the rotating rod rotates on the fixed plate through the electric shaft. At the same time, the rotating rod collides with the asphalt concrete waste continuously entering the feed barrel, so that the asphalt concrete waste can enter the feed barrel evenly. When the rotating rod rotates, the cleaning plate slides in the sliding groove through the sliding rod through the centrifugal force, so that the cleaning plate can contact and rotate with the inner wall of the feed barrel. Since the asphalt concrete waste itself is sticky, it is avoided that part of the asphalt concrete waste will adhere to the inner side of the feed barrel during feeding, thereby interfering with the spraying dust reduction work and crushing work.

[0017] 3. The present invention sets a screening mechanism. When the asphalt concrete waste crushed by the crushing roller falls on the screen plate, the motor is turned on and the screen plate is driven by the motor output end to move up and down in the inner cavity of the crushing box, so as to screen the crushed asphalt concrete waste. When the motor output end drives the screen plate to move downward, the screen plate contacts the ejection assembly, and the ejection assembly cleans and ejects the mesh of the screen plate, so as to avoid clogging of the mesh on the screen plate when the crushed asphalt concrete waste is screened, thereby interfering with the screening work.

[0018] 4. The present invention provides a scraper assembly. When a large amount of asphalt concrete waste is squeezed and impacted by the extrusion frame, the extrusion frame is driven to move downward through the first telescopic rod, so that the extrusion frame drives the square plate to move downward through the connecting rod. Since the discharge shell is wide at the top and narrow at the bottom, when the extrusion frame moves downward, the edge of the connecting sleeve and the inner side of the discharge shell continue to move against each other, so that the connecting sleeve drives the scraper to shrink and slide on the long plate of the square plate, and at the same time squeezes the seventh spring, so that the square plate can drive the scraper to follow the extrusion frame and move in contact with the inner side of the discharge shell, and at the same time can move against the inner side of the discharge shell for self-adjustment, thereby cleaning and scraping off the asphalt attached to the inner side of the discharge shell, avoiding the phenomenon that part of the asphalt in the asphalt concrete waste melts, so that it will stick to the inner side of the discharge shell during discharging.

[0036] Embodiment 2, use Figure 5-Figure 8 The low-carbon cold-regenerated asphalt concrete waste processing and regeneration device of the present invention is described as follows:

[0037] like Figure 5-Figure 8 It is shown that a low-carbon cold regenerated asphalt concrete waste processing and regeneration device of the present invention is based on the first embodiment;

[0038] The screening mechanism 64 includes a screen plate 642, the side of the screen plate 642 is slidably connected to the inner side of the crushing box 61, the two sides of the crushing box 61 are fixedly connected to the motor 641, the output end of the motor 641 is fixedly connected to the top of the screen plate 642, the inner side of the crushing box 61 is fixedly connected to a connecting frame 643, the connecting frame 643 is arranged at the bottom of the screen plate 642, and the top of the connecting frame 643 is fixedly connected to an ejection assembly 644; when the asphalt concrete waste crushed by the crushing roller 63 falls on the screen plate 642, by turning on the motor 641, The output end of the motor 641 drives the screen plate 642 to move up and down in the inner cavity of the crushing box 61, so as to screen the crushed asphalt concrete waste.

At the same time, when a large amount of asphalt concrete waste is extruded and impacted by the extrusion frame 654, it can drive the extrusion frame 654 to move downward through the first telescopic rod 653, so that the extrusion frame 654 drives the scraper assembly 658 to clean the inner side of the discharge housing 651, thereby avoiding the heat generated when the crushing roller 63 squeezes and crushes the asphalt concrete waste, causing part of the asphalt in the asphalt concrete waste to melt, so that it will adhere to the inner side of the discharge housing 651 during discharge, making it difficult to fall naturally;

[0041] The scraper assembly 658 includes a connecting rod 6581, one end of which is fixedly connected to the connecting shaft 656, and the other end of the connecting rod 6581 is fixedly connected to a square plate 6582, which is composed of two plates, one long and one short. Both sides of the long plate of the square plate 6582 are slidably connected to scrapers 6583, and the side of the scraper 6583 away from the square plate 6582 is fixedly connected to a connecting sleeve 6585, and both sides of the short plate of the square plate 6582 are fixedly connected to a second telescopic rod 65 84, one end of the second telescopic rod 6584 away from the short plate of the square plate 6582 is fixedly connected to the side of the connecting sleeve 6585, and a seventh spring 6586 is sleeved on the second telescopic rod 6584, one end of the seventh spring 6586 is fixedly connected to the connecting sleeve 6585, and the other end of the seventh spring 6586 is fixedly connected to the short plate of the square plate 6582, and one end of the sixth spring 657 away from the extrusion frame 654 is fixedly connected to the short plate of the square plate 6582; when a large amount of asphalt concrete waste is squeezed When the pressing frame 654 performs extrusion impact, it drives the extrusion frame 654 to move downward through the first telescopic rod 653, so that the extrusion frame 654 drives the square plate 6582 to move downward through the connecting rod 6581. Since the discharge housing 651 is set to be wide at the top and narrow at the bottom, when the extrusion frame 654 moves downward, the edge of the connecting sleeve 6585 and the inner side of the discharge housing 651 continue to move against each other, so that the connecting sleeve 6585 drives the scraper 6583 to move on the long plate of the square plate 6582. It shrinks and slides, and at the same time, squeezes the seventh spring 6586, so that the square plate 6582 can drive the scraper 6583 to follow the extrusion frame 654 and move in contact with the inner side of the discharge shell 651, and at the same time can move against the inner side of the discharge shell 651 for self-adjustment, thereby cleaning and scraping off the asphalt attached to the inner side of the discharge shell 651, to avoid the phenomenon that part of the asphalt in the asphalt concrete waste melts, so that it will stick to the inner side of the discharge shell 651 during discharge.

[0042] The specific workflow is as follows:

[0043] During operation, the asphalt concrete waste is transported to the crushing component 6, the crushing component 6 crushes the asphalt concrete waste, and the crushed asphalt concrete waste falls on the conveying component 2. The conveying component 2 transports the crushed asphalt concrete waste to the conveying component 3, and the conveying component 3 drives the crushed asphalt concrete waste into the discharging component 4, and the discharging component 4 performs the discharging work;

[0044] By conveying the asphalt concrete waste into the crushing box 61, the waste passes through the feeding mechanism 62, and the crushing roller 63 is driven by the external motor to rotate and crush the asphalt concrete waste in the crushing box 61. At the same time, by turning on the motor 641, the screening mechanism 64 is driven by the output end of the motor 641 to screen the crushed asphalt concrete waste, and the screened asphalt concrete waste falls onto the conveying component 2 through the discharging mechanism 65;

[0045] By continuously conveying the asphalt concrete waste into the crushing box 61, the asphalt concrete waste continuously impacts the rotating rod 624, and by turning on the driving motor at the bottom of the electric rotating shaft 623, the output end of the driving motor at the bottom of the electric rotating shaft 623 drives the electric rotating shaft 623 to rotate on the fixed plate 622, so that the rotating rod 624 rotates on the fixed plate 622 through the electric rotating shaft 623. At the same time, when the rotating rod 624 rotates, the rotating rod 624 and the extrusion plate 628 are squeezed, and the extrusion plate 628 drives the arc plate 629 to move in the water tank 626 through the extrusion rod 627. The circular arc plate 629 squeezes the water in the water tank 626 and sprays the water in the water tank 626 through the spray head 6211. When the asphalt concrete waste is continuously fed, the water mist sprayed by the spray head 6211 can be used to spray and reduce dust around the feed barrel 621, thereby avoiding the phenomenon of dust floating when the asphalt concrete waste is continuously discharged. At the same time, a contact component 625 is provided on the inner side of the rotating rod 624. When the rotating rod 624 rotates, the inner side of the feed barrel 621 can be cleaned through the contact component 625.

[0046] When the asphalt concrete waste continues to enter the feed barrel 621, the asphalt concrete waste continuously impacts the rotating rod 624, so that the rotating rod 624 rotates on the fixed plate 622 through the electric rotating shaft 623, and at the same time, the rotating rod 624 impacts the asphalt concrete waste that continues to enter the feed barrel 621, so that the asphalt concrete waste can enter the feed barrel 621 evenly. When the rotating rod 624 rotates, the cleaning plate 6254 slides in the sliding groove 6251 through the sliding rod 6253 through the centrifugal force, so that the cleaning plate 6254 can contact and rotate with the inner wall of the feed barrel 621. Since the asphalt concrete waste itself is sticky, it is avoided that part of the asphalt concrete waste will be attached to the inner side of the feed barrel 621 during feeding, thereby interfering with the spraying dust reduction work and the crushing work;

[0047] When the asphalt concrete waste material crushed by the crushing roller 63 falls on the screen plate 642, the motor 641 is turned on, and the screen plate 642 is driven by the output end of the motor 641 to move up and down in the inner cavity of the crushing box 61, so as to screen the crushed asphalt concrete waste material. When the output end of the motor 641 drives the screen plate 642 to move downward, when the screen plate 642 contacts the ejection assembly 644, the ejection assembly 644 cleans and ejects the mesh of the screen plate 642, so as to avoid clogging of the mesh on the screen plate 642 when the crushed asphalt concrete waste material is screened, thereby interfering with the screening work.

[0048] When the screen plate 642 is driven by the output end of the motor 641 to move downward, when the screen plate 642 is squeezed by the ejector pin 6445, the ejector pin 6445 can eject the impurities stuck in the mesh of the screen plate 642. At the same time, when the screen plate 642 is squeezed and contacted with the contact plate 6446, the contact plate 6446 can move against the inner side of the mesh of the screen plate 642, thereby preventing the asphalt in the asphalt concrete waste from adhering to the inner side of the mesh of the screen plate 642 when the asphalt concrete waste passes through the mesh of the screen plate 642. If it is not cleaned for a long time, a large amount of asphalt residue will accumulate on the inner wall of the mesh, which will interfere with the screening work. At the same time, the material of the contact plate 6446 is hard plastic material. When the screen When the mesh plate 642 and the contact plate 6446 are released from the extrusion contact, the contact plate 6446 can perform an elastic rebound effect through its own elastic action, and after the contact plate 6446 cleans the inner side of the mesh, the asphalt impurities attached to itself are bounced off. When the asphalt impurities blocked in the mesh are tightly stuck between the inner wall of the mesh, when the extrusion force of the ejector pin 6445 and the impurities is greater than the tensile force of the third spring 6447, the ejector pin 6445 moves downward through the slide bar 6444, and the slider 6443 drives the slide bar 6444 to move in the notch 6442. At the same time, the buffering work of the third spring 6447 is performed to avoid the phenomenon that when the extrusion force between the ejector pin 6445 and the impurities is too large, the ejector pin 6445 will be squeezed and damaged.

[0049] When the screened asphalt concrete waste continues to fall into the discharge housing 651 and is discharged through the discharge port 652, when a large amount of asphalt concrete waste is squeezed and impacted by the extrusion frame 654, the extrusion frame 654 can be driven to move downward through the first telescopic rod 653, so that the extrusion frame 654 drives the scraper assembly 658 to clean the inner side of the discharge housing 651, thereby avoiding the heat generated when the crushing roller 63 squeezes and crushes the asphalt concrete waste, causing part of the asphalt in the asphalt concrete waste to melt, so that it will adhere to the inner side of the discharge housing 651 when discharging, and it is difficult to fall naturally;

[0050] When a large amount of asphalt concrete waste is squeezed and impacted by the extrusion frame 654, the extrusion frame 654 is driven to move downward through the first telescopic rod 653, so that the extrusion frame 654 drives the square plate 6582 to move downward through the connecting rod 6581. Since the discharge shell 651 is wide at the top and narrow at the bottom, when the extrusion frame 654 moves downward, the edge of the connecting sleeve 6585 and the inner side of the discharge shell 651 continue to move against each other, so that the connecting sleeve 6585 drives the scraper 6583 to move on the square plate. The long plate 6582 shrinks and slides, and at the same time, the seventh spring 6586 is squeezed, so that the square plate 6582 can drive the scraper 6583 to follow the extrusion frame 654 and move in contact with the inner side of the discharge shell 651, and at the same time, it can move against the inner side of the discharge shell 651 for self-adjustment, and then clean and scrape off the asphalt attached to the inner side of the discharge shell 651, so as to avoid the phenomenon that part of the asphalt in the asphalt concrete waste melts, so that it will stick to the inner side of the discharge shell 651 during discharge.
