[0002] Asphalt pavement has many vehicles passing by, and after a long time, the surface of the asphalt pavement will be damaged, such as potholes, cracks, ruts, cracks, bulges, looseness, and exposure. At this time, we need to repair the asphalt pavement. In the process of highway maintenance and repair, we usually have two methods of construction, one is large-scale milling and recycling, the other is small-scale cutting and filling with new materials.

[0003] In the Chinese utility model patent application number: CN219032890U, there is disclosed a road asphalt heating device, wherein a control panel is fixed in the middle of the heating vehicle; a movable ball joint is fixed on the side of the control panel; a straight rod is fixed in the middle of the movable ball joint; a sleeve is fixed in the middle of the straight rod; the sleeve is provided with multiple groups in the middle of the straight rod; a flame head is slidably connected to the heating vehicle inside the sleeve; and a flame nozzle is fixed at the end of the flame head. Although this road asphalt heating device can visually see the repair status of the road surface, each time it is used, the straight rods on both sides need to be opened in turn for use, which is very cumbersome and inconvenient to use. At the same time, after the straight rod is opened, it is located at the end close to the user. The heat generated when the flame device is used may cause burns to the user. In addition, the straight rod with the flame device installed is exposed to the outside and is easily exposed to wind and sun, thereby rusting.

[0004] Therefore, it is necessary to propose a small tool for processing cold joints and rough surfaces of asphalt concrete to solve the above problems. Utility Model Content

[0036] Specifically, references 6 and Figure 8 The support plate 107 is fixedly connected to a limiting frame 121 on one side close to the driven meshing disk 112. The limiting frame 121 is used to limit the contact position between the driven meshing disk 112 and the active meshing disk 111 to prevent the driven meshing disk 112 from extending excessively. The driven meshing disk 112 rotates within the limiting frame 121.

[0037] Specifically, reference 1 and Figure 5 A cover plate 122 is provided on the top of the adjustment chamber 105 , and the cover plate 122 covers the top of the adjustment chamber 105 to prevent foreign matter from entering. A driven bevel gear 114 is rotatably connected to the bottom.

The control device 127 is connected to the fuel device 102 and the heating device 104 through a pipeline. A flame nozzle is installed at the bottom of the heating device 104.

[0040] Specifically, referring to 3 , a guide rod 128 is fixedly connected between the symmetrical support plates 107 , and the guide rod 128 is used to stabilize the lateral movement of the adjustment device 108 , and the moving frame 117 slides laterally on the outer wall of the guide rod 128 .

[0041] In this embodiment, the fuel device 102 is installed on the heating vehicle 101 and connected to the control device 127 through a pipeline. The control device 127 is connected to the heating devices 104 on both sides of the heating vehicle 101 through a pipeline. When in use, the heating devices 104 on both sides are turned on by rotating the round handle 126, and the heating devices 104 are controlled by the control device 127 to perform flame heating work, and the heating status of the asphalt pavement during operation can be intuitively observed, and the heating vehicle 101 can be moved and heated by pushing it back and forth. After the heating device 104 is turned on, it is located at the end away from the handle of the heating vehicle 101, which can reduce the impact of the temperature on the construction personnel when the heating device 104 is working;

[0042] When the heating device 104 needs to be opened from both sides of the heating vehicle 101, the round handle 126 on the rotating adjustment device 108 is used. The round handle 126 drives the turbine 118 to rotate through the worm 119, and the turbine 118 drives the active meshing discs 111 on both sides to rotate through the connecting rod 116. At this time, the springs 120 on both sides push the driven meshing disc 112 to fit together with the active meshing disc 111. When the active meshing disc 111 rotates, it drives the driven meshing disc 112 to rotate together. The driven meshing disc 112 is connected by the meshing of the spline block 110 and the spline sleeve 109, driving the active bevel gear 113 to rotate. The active bevel gear 113 drives the transmission assembly 115 to transmit through the driven bevel gear 114 at the top, so that the other end of the transmission assembly 115 drives the heating device 104 to rotate, thereby opening the heating device 104 to both sides. After opening, the synchronous heating work on both sides can be carried out.

[0043] When it is necessary to open the heating device 104 on one side, the movable frame 117 is moved to the side that needs to be opened through the square handle 125, and the square handle 125 drives the adjusting device 108 to move. When the adjusting device 108 moves, the active meshing disk 111 and the driven meshing disk 112 are fitted together to press it into the limit frame 121. At this time, the spring 120 between the driven meshing disk 112 and the support plate 107 is compressed, and the spline block 110 is inserted into the spline sleeve 109. The active meshing disk 111 on the other side will be disconnected from the driven meshing disk 112. At this time, the worm 119 is rotated by the round handle 126, and the pressed side will rotate normally, and then the heating device 104 on this side will be opened, and the other side will not be opened because it is disconnected from the active meshing disk 111.

[0044] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
