Asphalt pavements are subject to widespread use, they are inevitably susceptible to road damage such as rutting, cracks, looseness, cracking, oily potholes, and peeling. Failure to carry out timely and effective maintenance will further exacerbate and spread these road damage, accelerating asphalt pavement damage and compromising highway safety.

[0021] Compared with the prior art, the present invention has the following beneficial effects:
[0022] 1. The present invention utilizes the stirring shaft to rotate so that the magnetic block rotates with the stirring shaft, so that the magnetic field of the magnetic block changes continuously during the rotation process. The magnetic block generates electromagnetic induction with the electromagnetic coil on the outer wall of the fixed ring during the rotation process. According to Faraday's law of electromagnetic induction, the change of the magnetic field will generate an induced current in the electromagnetic coil, and the faster the rotation speed of the stirring shaft, the greater the current generated. The current generated by the electromagnetic coil is transmitted to the electric valve on the outer wall of the feed barrel through a wire. The opening and closing degree of the electric valve is proportional to the input current, that is, the greater the current, the greater the opening and closing degree of the electric valve. The rotation speed of the stirring shaft can dynamically adjust the entry speed of the material, avoiding the problem of mismatch between the material feeding speed and the stirring speed, ensuring the uniformity and efficiency of the stirring process, and the material feeding speed is proportional to the stirring intensity, so that the stirring mechanism can flexibly adjust the stirring intensity according to actual needs, thereby improving the stirring efficiency and quality.
[0023] 2. The present invention drives the stirring shaft to start rotating through motor A. When the stirring shaft starts rotating, the stirring shaft drives the control ring to start rotating. The rotation of the control ring causes the magnetic block in the sliding groove to slide outward under the action of centrifugal force, so that the magnetic block pulls the rack A upward through the connecting rope. Due to the meshing relationship between the rack A and the gear, the rack A moves synchronously and drives the gear to start rotating, so that the gear drives the stirring rod to flip a certain angle. The change in the flipping angle of the stirring rod causes the stirring area of the asphalt mixture to change. By adjusting the flipping angle of the stirring rod, the stirring force can be accurately controlled to avoid excessive stirring of the asphalt mixture. By changing the stirring area of the stirring rod, the stirring force can be flexibly adjusted according to the material entry speed.
[0024] 3. The present invention generates negative pressure through a suction pump, driving the rotating rod to rotate the cam, causing the vibrating rod to vibrate the screen plate, screening out lumps in the material, preventing blockage at the discharge head and improving construction quality. Simultaneously, the connecting rope pulls the pull rod, driving the circular plate in the vacuum cylinder upward, reducing the pressure in the gas tank. The push rod moves downward, driving rack B, adjusting the valve stem to rotate and changing the suction force in the suction pipe. As the stirring mechanism speed increases, the centrifugal force of the magnetic block increases, pulling the connecting rope to increase the distance the circular plate moves upward. The vibration frequency is adaptively adjusted to ensure that the screening efficiency matches the stirring frequency, effectively separating impurities and lumps, and improving screening efficiency.

DETAILED DESCRIPTION
[0037] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0038] See Figures 1 to 10 As shown, the present invention provides an asphalt road construction pavement maintenance device with a waste collection function, comprising a vehicle body 1, an asphalt tank 2 is installed at the top end of the vehicle body 1, and a discharge head 3 is installed at the bottom end of the asphalt tank 2;
[0039] The interior of the asphalt tank 2 is provided with a stirring mechanism 4 for stirring the material. The stirring mechanism 4 includes a stirring shaft 402 that rotates inside the asphalt tank 2. The outer wall of the stirring shaft 402 is provided with a control ring 403. The bottom end of the control ring 403 is provided with a sliding groove 404. A magnetic block 405 slides inside the sliding groove 404. A stirring rod 406 is rotated on the outer wall of the stirring shaft 402. One end of the magnetic block 405 is provided with a connecting rope 407. The connecting rope 407 passes through the interior of the stirring shaft 402 and is equipped with a pull rod 408 at one end. A rack A409 is installed at the bottom end of the pull rod 408. A gear 410 that meshes with the rack A409 is installed at one end of the stirring rod 406.
[0040] It should be noted that when the asphalt mixture needs to be stirred, the material is added from the top of the feed barrel 501, and the motor A401 is started, so that the motor A401 drives the stirring shaft 402 to start rotating. When the stirring shaft 402 starts to rotate, the stirring shaft 402 drives the control ring 403 to start rotating. The rotation of the control ring 403 causes the magnetic block 405 in the sliding groove 404 to slide outward under the action of centrifugal force, so that the magnetic block 405 pulls the rack A409 upward through the connecting rope 407. The meshing relationship with the gear 410 causes the rack A409 to move synchronously and drive the gear 410 to start rotating, so that the gear 410 drives the stirring rod 406 to flip a certain angle. The change in the flipping angle of the stirring rod 406 causes the stirring area of the asphalt mixture by the stirring rod 406 to change. By adjusting the flipping angle of the stirring rod 406, the stirring force can be accurately controlled to avoid excessive stirring of the asphalt mixture, and by changing the stirring area of the stirring rod 406, the stirring force can be flexibly adjusted according to the material entry speed.
[0041] The outer side of the control ring 403 is provided with a feeding mechanism 5 for controlling the feeding speed. The feeding mechanism 5 includes a feeding barrel 501 mounted on the top of the asphalt tank 2. The outer wall of the feeding barrel 501 is mounted with an electric valve 502. The inner top of the asphalt tank 2 is provided with a fixing ring 503, which is sleeved on the outer wall of the control ring 403. The outer wall of the fixing ring 503 is provided with an electromagnetic coil 504. A wire 505 is provided between the electric valve 502 and the electromagnetic coil 504.
[0042] It should be noted that when the stirring shaft 402 is rotating, the magnetic block 405 rotates along with the stirring shaft 402, so that the magnetic field of the magnetic block 405 changes continuously during the rotation. The magnetic block 405 generates electromagnetic induction with the electromagnetic coil 504 on the outer wall of the fixed ring 503 during the rotation. According to Faraday's law of electromagnetic induction, the change in the magnetic field will generate an induced current in the electromagnetic coil 504, and the faster the rotation speed of the stirring shaft 402, the greater the current generated. The current generated by the electromagnetic coil 504 is transmitted to the electric valve 502 on the outer wall of the feeding barrel 501 through the wire 505. The opening and closing degree of the electric valve 502 is proportional to the input current, that is, the greater the current, the greater the opening and closing degree of the electric valve 502. The rotation speed of the stirring shaft 402 can dynamically adjust the material entry speed, avoid the problem of mismatch between the material feeding speed and the stirring speed, ensure the uniformity and efficiency of the stirring process, and the material feeding speed is proportional to the stirring intensity, so that the stirring mechanism 4 can flexibly adjust the stirring intensity according to actual needs to improve the stirring efficiency and quality.
[0043] A collection mechanism 6 for collecting waste is provided at the top of the vehicle body 1;
[0044] The bottom end of the feed cylinder 501 is provided with a vibration mechanism 7 for screening the material;
[0045] The bottom end of the stirring shaft 402 is provided with an adjusting mechanism 8 for adjusting the material screening frequency.
[0046] See Figures 6 and 7 As shown, the vibration mechanism 7 includes a shell 701, a screen plate 702 is hinged to the inner wall of the shell 701, a vibration rod 710 for vibrating the screen plate 702 is provided at the bottom of the shell 701, and a driving assembly for driving one end of the vibration rod 710 is provided on one side of the asphalt tank 2.
[0047] See Figures 6 and 7 As shown, the drive assembly includes a cylinder 703 installed on the side wall of the asphalt tank 2, a rotating rod 704 rotates inside the cylinder 703, one end of the rotating rod 704 is sleeved with a blade 705, and one end of the rotating rod 704 that passes through the interior of the asphalt tank 2 is installed with a cam 706.
[0048] See Figures 6 and 7 As shown, an L-shaped plate 707 is welded to the bottom end of the shell 701, and multiple groups of moving rods 708 slide on the surface of the L-shaped plate 707. The top of the moving rod 708 is provided with a mounting groove 709, and the vibration rod 710 slides inside the mounting groove 709. The bottom end of the moving rod 708 is installed with a connecting plate 711.
[0049] It should be noted that when the material is added, the suction pump 602 is turned on, and negative pressure is formed in the suction pipe 603. External air flows in at a high speed through the inlet of the cylinder 703, impacting the blade surface 705, driving the rotating rod 704 to rotate clockwise around the axis, so that the rotating rod 704 synchronously drives the cam 706 to rotate, so that the cam 706 pushes the connecting plate 711 to move up and down, and further the connecting plate 711 drives the moving rod 708 to move, so that the moving rod 708 drives the vibrating rod 710 to vibrate the screen plate 702, thereby screening the agglomerated materials in the material. The screened materials enter the waste box 714 for recycling through the feed pipe 713. The vibration screening function of the screen plate 702 can effectively separate the agglomerated materials in the material, avoid these agglomerated materials from clogging the discharge head 3 during discharge, reduce the construction interruption caused by the blockage of the discharge head 3, and the screened materials are more uniform, which can ensure the quality of the materials entering the asphalt tank 2, thereby improving the construction quality of the asphalt mixture.
[0050] See Figure 10 As shown, a spring A712 is provided inside the mounting groove 709 , the top end of the spring A712 is fixedly connected to the bottom end of the vibration rod 710 , and the bottom end of the spring A712 is fixedly connected to the inner wall of the mounting groove 709 .
[0051] See Figures 5 and 6 As shown, the side wall of the housing 701 is connected to a delivery pipe 713 , and one end of the delivery pipe 713 is connected to a waste box 714 .
[0052] See Figures 6 to 9 As shown, the adjustment mechanism 8 includes a vacuum cylinder 801 welded to the bottom end of the stirring shaft 402, a circular plate 802 slides inside the vacuum cylinder 801, a spring B803 is provided inside the vacuum cylinder 801, an air storage tank 804 is installed on the side wall of the asphalt tank 2, a connecting pipe 805 is connected between the vacuum cylinder 801 and the air storage tank 804, a push rod 806 slides inside the air storage tank 804, and a rack B807 is installed on one end of the push rod 806 that passes through the interior of the air storage tank 804.
[0053] It should be noted that when the connecting rope 407 pulls the pull rod 408 to move, the pull rod 408 synchronously drives the circular plate 802 inside the air pump 801 to move upward. The circular plate 802 moves upward and sucks the gas inside the gas tank 804 into the air pump 801 through the connecting pipe 805, so that the pressure inside the gas tank 804 is reduced. Due to the reduction in the internal pressure of the gas tank 804, the push rod 806 moves downward along the inside of the gas tank 804 under the action of the spring B803. The downward movement of the push rod 806 drives the rack B807 to move downward synchronously. The rack B807 is meshed with the gear ring at one end of the valve stem 809. The downward movement of the rack B807 drives the valve stem 809 to rotate The rotation of the valve stem 809 adjusts the opening and closing degree of the regulating valve 808, and the opening and closing degree of the regulating valve 808 changes the suction force of the suction pipe 603. When the rotation speed of the stirring mechanism 4 increases, the centrifugal force of the magnetic block 405 is greater, and the distance the magnetic block 405 moves is farther, so that the magnetic block 405 pulls the connecting rope 407 to drive the pull rod 408 to a higher distance, thereby increasing the upward movement distance of the circular plate 802 inside the vacuum cylinder 801, and then the vibration frequency of the vibration mechanism 7 can be adaptively adjusted according to the rotation speed of the stirring mechanism 4, ensuring that the screening efficiency matches the stirring frequency, thereby being able to more effectively separate impurities and agglomerates in the material and improve the screening efficiency.
[0054] See Figures 1 to 5 As shown, the collecting mechanism 6 includes a collecting box 601, a suction pump 602 is installed on the top of the collecting box 601, an air suction pipe 603 is installed on the side wall of the suction pump 602, the outer wall of the air suction pipe 603 is connected to a dust suction pipe 604, and a suction head 605 is installed at one end of the dust suction pipe 604.
[0055] It should be noted that after the material preparation is completed, the maintenance device is moved to the road surface to be repaired. By turning on the power of the suction pump 602, the impeller rotates at high speed to form a negative pressure environment in the suction pipe 603. The negative pressure airflow is transmitted to the extraction head 605 through the dust suction pipe 604, and a high-speed airflow is formed at the port of the extraction head 605. The extraction head 605 is close to the crack surface. The negative pressure airflow carries the waste materials in the gap, such as crushed asphalt, gravel, dust, etc., into the suction pipe 603 through the dust suction pipe 604, and is recovered to the collection box 601 for storage, so as to ensure that the crack surface is cleaner, so that the cleaned crack surface is conducive to better bonding of the grouting material with the original road surface, thereby improving the repair quality and extending the service life of the road surface.
[0056] See Figure 9 As shown, a regulating valve 808 is installed on the outer wall of the intake pipe 603, and a valve stem 809 is installed on the outer wall of the regulating valve 808. One end of the valve stem 809 is provided with a gear ring that meshes with the rack B807.
[0057] See Figure 2 As shown, a motor A401 is installed on the top of the stirring shaft 402, and a valve is installed on the outer wall of the discharge head 3.
[0058] Working principle: When the asphalt mixture needs to be stirred, the material is added from the top of the feed barrel 501 and the motor A401 is started, so that the motor A401 drives the stirring shaft 402 to start rotating. When the stirring shaft 402 starts rotating, the stirring shaft 402 drives the control ring 403 to start rotating. The rotation of the control ring 403 causes the magnetic block 405 in the sliding groove 404 to slide outward under the action of centrifugal force, so that the magnetic block 405 pulls the rack A409 upward through the connecting rope 407. The meshing relationship of the gear 410 causes the rack A409 to move synchronously and drive the gear 410 to start rotating, so that the gear 410 drives the stirring rod 406 to flip a certain angle. The change in the flip angle of the stirring rod 406 causes the stirring area of the asphalt mixture to change. By adjusting the flip angle of the stirring rod 406, the stirring force can be accurately controlled to avoid excessive stirring of the asphalt mixture. By changing the stirring area of the stirring rod 406, the stirring force can be flexibly adjusted according to the material feeding speed.
[0059] At the same time, when the stirring shaft 402 is rotating, the magnetic block 405 rotates along with the stirring shaft 402, so that the magnetic field of the magnetic block 405 changes continuously during the rotation process. The magnetic block 405 generates electromagnetic induction with the electromagnetic coil 504 on the outer wall of the fixed ring 503 during the rotation process. According to Faraday's law of electromagnetic induction, the change in the magnetic field will generate an induced current in the electromagnetic coil 504, and the faster the rotation speed of the stirring shaft 402, the greater the current generated. The current generated by the electromagnetic coil 504 is transmitted to the electric valve 502 on the outer wall of the feeding barrel 501 through the wire 505. The opening and closing degree of the electric valve 502 is proportional to the input current, that is, the greater the current, the greater the opening and closing degree of the electric valve 502. The rotation speed of the stirring shaft 402 can dynamically adjust the material entry speed, avoid the problem of mismatch between the material feeding speed and the stirring speed, ensure the uniformity and efficiency of the stirring process, and the material feeding speed is proportional to the stirring intensity, so that the stirring mechanism 4 can flexibly adjust the stirring intensity according to actual needs, thereby improving the stirring efficiency and quality.
[0060] When the material is added, the suction pump 602 is turned on, and negative pressure is formed in the suction pipe 603. External air flows in at a high speed through the inlet of the cylinder 703, impacting the blade surface 705, driving the rotating rod 704 to rotate clockwise around the axis, so that the rotating rod 704 synchronously drives the cam 706 to rotate, so that the cam 706 pushes the connecting plate 711 to move up and down, and further the connecting plate 711 drives the moving rod 708 to move, so that the moving rod 708 drives the vibrating rod 710 to vibrate the screen plate 702, thereby screening the agglomerated materials in the material, and the screened materials enter the waste box 714 for recycling through the feeding pipe 713. The vibration screening function of the screen plate 702 can effectively separate the agglomerated materials in the material, so as to avoid these agglomerated materials from clogging the discharge head 3 during discharging, thereby reducing the construction interruption caused by the blockage of the discharge head 3, and the screened materials are more uniform, which can ensure the quality of the materials entering the asphalt tank 2, thereby improving the construction quality of the asphalt mixture;
[0061] In addition, when the connecting rope 407 pulls the pull rod 408 to move, the pull rod 408 synchronously drives the circular plate 802 inside the air pump 801 to move upward. The circular plate 802 moves upward to suck the gas inside the gas tank 804 into the air pump 801 through the connecting pipe 805, so that the pressure inside the gas tank 804 is reduced. As the pressure inside the gas tank 804 is reduced, the push rod 806 moves downward along the inside of the gas tank 804 under the action of the spring B803. The downward movement of the push rod 806 drives the rack B807 to move downward synchronously. The rack B807 is meshed with the gear ring at one end of the valve stem 809. The downward movement of the rack B807 drives the valve stem 809 to rotate, and the valve The rotation of the rod 809 adjusts the opening and closing degree of the regulating valve 808, and the opening and closing degree of the regulating valve 808 changes the suction force of the suction pipe 603. When the rotation speed of the stirring mechanism 4 increases, the centrifugal force of the magnetic block 405 is greater, and the distance the magnetic block 405 moves is farther, so that the magnetic block 405 pulls the connecting rope 407 to drive the pull rod 408 to a greater distance, thereby increasing the upward movement distance of the circular plate 802 inside the vacuum cylinder 801, and then the vibration frequency of the vibration mechanism 7 can be adaptively adjusted according to the rotation speed of the stirring mechanism 4, ensuring that the screening efficiency matches the stirring frequency, thereby more effectively separating impurities and agglomerates in the material and improving the screening efficiency;
[0062] When the material preparation is completed, the maintenance device is moved to the road surface to be repaired. By turning on the power of the suction pump 602, the impeller rotates at high speed to form a negative pressure environment in the suction pipe 603. The negative pressure airflow is transmitted to the extraction head 605 through the dust suction pipe 604, and a high-speed airflow is formed at the port of the extraction head 605. The extraction head 605 is close to the crack surface. The negative pressure airflow carries the waste materials in the gap, such as crushed asphalt, gravel, dust, etc., into the suction pipe 603 through the dust suction pipe 604, and is recovered to the collection box 601 for storage, so as to ensure that the crack surface is cleaner, so that the cleaned crack surface is conducive to better bonding of the grouting material with the original road surface, thereby improving the repair quality and extending the service life of the road surface.
