[0026] The embodiments of the present invention will be described in detail below, and the examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0027] As Figures 1 to 7As shown in the figure, a device for treating the paving joint of an asphalt mixture pavement according to the present invention includes a vehicle body 10, a frame 11 is installed on the vehicle body 10, a hydraulic cylinder 12 is hinged to the top of the frame 11, the output end of the hydraulic cylinder 12 is hinged to a rotating frame 13, the rotating frame 13 is hinged to the frame 11, a rotating cylinder 14 is rotatably connected to the end of the rotating frame 13, two first rotating rods 15 and two second rotating rods 16 are connected to the outer peripheral surface of the rotating cylinder 14, the included angle between the first rotating rod 15 and the second rotating rod 16 is an obtuse angle, a cutting assembly, a cleaning assembly and a scraping assembly are arranged on the two first rotating rods 15, the scraping assembly is located between the cleaning assembly and the cutting assembly, the cutting assembly is used for cutting the asphalt mixture pavement, and the cleaning assembly and the scraping assembly are used for cleaning the cut asphalt mixture pavement so that there is no impurity at the joint. A coating assembly and a drying assembly are arranged between the two second rotating rods 16 and the vehicle body 10, the coating assembly is used for coating tack coat on the joint, and the drying assembly is used for drying the joint.

[0028] The hydraulic cylinder 12 can drive the rotating frame 13 to rotate, so that the rotating cylinder 14 and the rotating frame 13 can be adjusted to a suitable height according to the actual situation, which is convenient for subsequent treatment operations on the joint of the asphalt mixture pavement.

[0029] It should be noted that a driving member is arranged on the rotating frame 13, the driving member is connected to the rotating cylinder 14, and the driving member is used for driving the rotating cylinder 14 to rotate.

[0030] Such as Figures 1 - 5 , the cutting assembly includes a first rotating shaft that rotates with the first rotating rod 15, and two saw blades 17 are installed on the outer peripheral surface of the first rotating shaft.

[0031] When treating the joint, the first rotating shaft drives the two saw blades 17 to rotate, so that the two sides of the joint can be cut, thereby removing the part with insufficient thickness of the asphalt mixture pavement.

[0032] Such as Figures 1 - 5 , the cleaning assembly includes a support frame 20 connected to the first rotating rod 15, a cleaning brush roller 21 is rotatably connected to the support frame 20, a second rotating shaft 22 is connected to the cleaning brush roller 21, and a driving structure is arranged between the second rotating shaft 22, the first rotating shaft and the first rotating rod 15, and the driving structure is used for driving the first rotating shaft and the second rotating shaft 22 to rotate simultaneously.

[0033] Such as Figure 1 and Figure 3 , the driving structure includes a dual-axis motor 18 installed on the first rotating rod 15, one output end of the dual-axis motor 18 is connected to the first rotating shaft, and the other output end of the dual-axis motor 18 is connected to a first pulley 19, and the first pulley 19 is connected to a second pulley 23 connected to the second rotating shaft 22 through a belt drive.

[0034] When the joint is processed, the dual-axis motor 18 is started, and the shaft 1 drives the saw blade 17 to rotate and perform the cutting operation. At this time, the shaft 22 drives the cleaning brush roller 21 to rotate under the transmission action of the pulley 19, the belt and the pulley 23. As the cleaning brush roller 21 rotates, the small gravel generated after cutting and the dust inside the joint are cleaned.

[0035] It should be noted that a stabilizing frame for supporting the second rotating shaft 22 is provided on the rotating rod 15 , and the second rotating shaft 22 passes through the stabilizing frame and is rotatably connected to the stabilizing frame via a bearing, thereby ensuring the stability of the second rotating shaft 22 during rotation.

[0036] like Figure 2 , Figure 4 and Figure 5 The scraper assembly includes a support plate 30 connected to the rotating rod 15, one side of the support plate 30 is threadedly connected to an adjusting threaded rod 31, the top of the adjusting threaded rod 31 is fixedly connected to a rocker, the bottom of the adjusting threaded rod 31 is rotatably connected to a push plate 32 through a bearing, and the top side of the push plate 32 is fixedly connected to two guide rods 33 with a T-shaped cross-section, the guide rods 33 pass through the support plate 30 and are slidably connected to the support plate 30.

[0037] When processing the joint, the adjusting threaded rod 31 is moved downward by rotating the rocker, and the push plate 32 is moved under the guidance of the guide rod 33, and the push plate 32 is made to fit with the bottom side of the joint. After the cutting component cuts the part of the asphalt mixture pavement with insufficient thickness, the movement of the push plate 32 can push the larger volume of asphalt mixture gravel to move, and the impurities in the joint can be removed by cooperating with the cleaning component.

[0038] It should be noted that the length of the push plate 32 is the same as that of the cleaning brush roller 21 , and the length of the push plate 32 is equal to the maximum distance between the two saw blades 17 , so that the asphalt mixture gravel cut by the saw blades 17 can be fully cleaned.

[0039] like Figure 4 , Figure 6 and Figure 7 The coating brush assembly includes a coating brush roller 40 rotatably connected to the rotating rod 16 and a material barrel 41 arranged on the vehicle body 10. The material barrel 41 is connected to a delivery pump 42 through a pipeline. A delivery hose 43 is connected to a connection port of the delivery pump 42. The delivery hose 43 is connected to a nozzle 44 at one end away from the delivery pump 42. The nozzle 44 is located above the coating brush roller 40 and corresponds to the position of the coating brush roller 40. A displacement assembly is connected to the rotating rod 16. The displacement assembly is connected to the nozzle 44. The displacement assembly is used to drive the nozzle 44 to move so that the nozzle 44 can evenly spray the adhesive layer oil onto the coating brush roller 40.

[0040] As Figure 6 shown, the displacement assembly includes a mounting seat 45 connected to the second rotating rod 16. A linear module 46 is mounted on the mounting seat 45. The length direction of the linear module 46 is parallel to the length direction of the coating roller 40. A sliding seat 47 is connected to the linear module 46, and the sliding seat 47 is connected to the first nozzle 44.

[0041] After the cleaning operation of the butt joint is completed, by rotating the rotating cylinder 14, the first rotating rod 15 is raised and the second rotating rod 16 is lowered, so that the coating roller 40 contacts the bottom side of the joint. By moving the vehicle body 10, at this time, the coating roller 40 will rotate and apply the tack coat oil to the joint. During this process, the linear module 46 drives the sliding seat 47 and the first nozzle 44 to reciprocate. By starting the transfer pump 42, the tack coat oil located inside the material bucket 41 is transported to the first nozzle 44 through the transfer hose 43 and sprayed out through the first nozzle 44, so as to evenly spray the tack coat oil onto the coating roller 40, and further enable the coating roller 40 to perform the operation of applying the tack coat oil in a dimensioned manner.

[0042] As Figures 4 - 7 shown, the drying assembly includes a mounting block 51 installed at the end of the second rotating rod 16 and a hot air blower 52 installed on the vehicle body 10. A drying pipe 53 is connected to the mounting block 51, and a plurality of drying nozzles 54 are connected to the drying pipe 53. An air delivery hose 55 connected to the drying pipe 53 is connected to the air outlet of the hot air blower 52, and the air delivery hose 55 is communicated with the drying pipe 53.

[0043] When applying the tack coat oil, start the hot air blower 52. The generated hot air is transported to the inside of the drying pipe 53 through the air delivery hose 55 and then sprayed out through the plurality of drying nozzles 54, so as to perform a drying operation on the joint after applying the tack coat oil, accelerate the drying speed of the tack coat oil, thereby improving the drying efficiency, reducing the overall construction time, and improving the construction efficiency.

[0044] It should be noted that the drying pipe 53 is located at the middle position between the coating roller 40 and the vehicle body 10, and there is an angle between the mounting block 51 and the second rotating rod 16. The angle between the mounting block 51 and the second rotating rod 16 is an obtuse angle, which can avoid the situation that the drying nozzle 54 contacts the bottom side of the joint after the coating roller 40 contacts the bottom side of the joint, thereby ensuring the normal progress of the drying operation.

[0045] As Figure 4 、 Figure 6 and Figure 7, a water spraying assembly is arranged between the first rotating rod 15 and the vehicle body 10. The water spraying assembly is used for performing a water spraying and cooling operation on the saw blade 17 to reduce the temperature of the saw blade 17. The water spraying assembly includes a flow dividing pipe 60 installed on the first rotating rod 15 and a water tank 61 arranged on the vehicle body 10. The water tank 61 is connected with a water delivery pump 62 through a pipeline. The water outlet of the water delivery pump 62 is connected with a water delivery hose 63. The water delivery hose 63 is communicated with the flow dividing pipe 60. Two second nozzles 64 are connected to the flow dividing pipe 60. The positions of the second nozzles 64 correspond to those of the saw blade 17, and the second nozzles 64 correspond to the saw blade 17 one by one.

[0046] When the saw blade 17 is working for cutting, by starting the water delivery pump 62, the water inside the water tank 61 is delivered to the flow dividing pipe 60 through the water delivery hose 63, and then sprayed out through the two second nozzles 64, so as to spray the water onto the saw blade 17 and reduce the temperature of the saw blade 17, ensuring the stable operation of the saw blade 17.

[0047] After cutting, the push plate 32 can push the water away from the joint, and the cleaning brush roller 21 can clean the water in the joint. And in this process, the hot air blower 52 is started, and the drying air flow is sprayed out through the drying nozzle 54 to perform a drying operation on the inside of the joint, so as to remove the moisture at the joint, accelerate the drying speed of the joint, and further reduce the construction time.

[0048] Three support rods 111 are installed on the frame 11. The conveying hose 43, the air delivery hose 55 and the water delivery hose 63 are respectively lapped on one support rod 111.

[0049] The three support rods 111 are distributed along the height direction of the frame 11. By means of the three support rods 111, the interference between the conveying hose 43, the air delivery hose 55 and the water delivery hose 63 is avoided.

[0050] A counterweight 101 is arranged on the vehicle body 10. The counterweight 101 is used for increasing the weight of the vehicle body 10 to avoid the situation that the vehicle body 10 tilts due to uneven sinking.

[0051] It should be noted that the water tank 61 can be installed on the top side of the counterweight 101, and the material bucket 41 is arranged on the water tank 61, so that the overall layout is more compact and the installation space is saved.
