[0002] During the long-term use of asphalt pavement, various accidents often cause cracks, dents, and cracks on the asphalt pavement. At this time, the asphalt pavement needs to be repaired. Asphalt pavement repair uses heat to soften the asphalt, and then fills the cracks and potholes in the road surface to repair the damaged parts of the road surface.

[0003] The Chinese invention patent with the announcement number: CN111535135B discloses a petroleum asphalt coating machine for road pothole repair. This device pours petroleum asphalt into the heat-insulating storage box, then pushes the device to the pothole position, starts the electric push rod to make the pressure roller contact the road surface, and then uses the discharge hose to spray the petroleum asphalt into the pothole, starts the reduction motor, and the pressure roller moves left and right to flatten the petroleum asphalt without affecting the use of the road surface, thus completing the pothole repair. There is no need to use a maintenance vehicle to spray petroleum asphalt, which is more convenient.

[0004] In the above invention and the prior art, the method adopted is to directly fill the cracks. When repairing asphalt pavements with higher requirements, no matter the potholes are round holes, slanted holes or other irregular shapes, they need to be cut into right-angled rectangles, and at the same time, the four sides of the potholes must be parallel or perpendicular to the road markings. In this way, the repaired potholes have better repair quality. At the same time, in the process of road repair, the repair depth of some asphalt pavements needs to be controlled, but there is no device that can effectively control the construction depth in manual construction or prior art.

DETAILED DESCRIPTION

[0018] like Figures 1 to 3 and Figure 5 As shown, a small-scale asphalt heating patching equipment for road repair includes a vehicle body 101, a seat 102 is fixedly installed on the vehicle body 101, a support frame 104 is slidably installed on one end of the vehicle body 101, an adjusting cylinder 103 is fixedly installed on the vehicle body 101, and the other end of the adjusting cylinder 103 is fixedly connected to the support frame 104, a vibrating bucket 106 is slidably installed on the end of the support frame 104 away from the vehicle body 101, a vibrating cylinder 105 is fixedly installed on the vibrating bucket 106, and the other end of the vibrating cylinder 105 is fixedly installed on the support frame 104. After the vibrating cylinder 105 is started, it can drive the vibrating bucket 106 to reciprocate and generate vibration to assist the material in the vibrating bucket 106. The vibration bucket 106 is provided with an isolation plate 108 rotatably installed in it, and the isolation plate 108 divides the vibration bucket 106 into two spaces in the initial state. Handle pointers 107 are slidably installed at both ends of the connection between the isolation plate 108 and the vibration bucket 106. A card slot scale is provided on the outer wall of the vibration bucket 106, and the handle pointer 107 can be matched with the card slot scale on the vibration bucket 106. When the handle pointer 107 is pulled to move away from the vibration bucket 106, the handle pointer 107 can be operated to rotate the isolation plate 108 to connect the two spaces in the vibration bucket 106. One end of the vibration bucket 106 is provided with a plurality of diversion ports 211, and the diversion ports 211 are used to divert the material in the vibration bucket 106.

[0019] like Figures 3 to 5As shown, a heat-resistant bucket 201 is rotatably mounted on the support frame 104, and a plurality of heating nozzles 208 are rotatably mounted on the heat-resistant bucket 201. The heating nozzles 208 are staggered with the diversion port 211 on the vibration bucket 106 to prevent the material from falling on the heating nozzles 208. A circulating cylinder 207 is fixedly mounted on the heat-resistant bucket 201, and a driving swing rod 210 is fixedly mounted on the other end of the circulating cylinder 207. A plurality of switching slots are arranged on the driving swing rod 210. The heating nozzles 208 A swing rod 209 is fixedly installed at one end close to the driving swing rod 210. The swing rod 209 is set in the switching groove and contacts the switching groove. When the driving swing rod 210 moves, the swing rod 209 will be squeezed by the driving swing rod 210, so that the swing rod 209 will drive the heating nozzle 208 to rotate. When the heating nozzle 208 rotates, the heating area of ​​the heating nozzle 208 is expanded, so that the heating nozzle 208 can heat the asphalt pavement framed by the heat-resistant bucket 201 as soon as possible.

[0020] like Figure 3 to Figure 4 As shown, a softening claw 202 is rotatably installed on the heat-resistant bucket 201, and the softening claw 202 is used to crack the asphalt that has reached a predetermined temperature, so as to facilitate subsequent workers to carry out construction. Side telescopic rods 203 are also fixedly installed at both ends of the softening claw 202, and the side telescopic rod 203 is eccentrically arranged on the softening claw 202. A side rotating shaft 204 is also rotatably installed on the side telescopic rod 203. A rotating motor 206 is fixedly installed on the heat-resistant bucket 201, and a rotating screw 205 is fixedly installed on the output shaft of the rotating motor 206. The rotating screw 205 is connected to the rotating screw 205 by threads. A swing cylinder is also rotatably installed on the support frame 104. 109, the other end of the swing cylinder 109 is rotatably connected to the heat-resistant bucket 201, and the installation position of the swing cylinder 109 is at the end of the heat-resistant bucket 201 away from the softening claw 202. After the rotating motor 206 is started, the rotating screw 205 can drive the side shaft 204 to move away from the rotating motor 206, and then the side telescopic rod 203 is retracted to compensate for the displacement, and the side telescopic rod 203 will drive the softening claw 202 to rotate, so that the angle between the softening claw 202 and the heat-resistant bucket 201 will be adjusted. When this angle is larger, the depth of the softening claw 202 after penetrating into the ground is deeper, so that it can adapt to asphalt paved roads of different thicknesses.

[0021] Working principle: When the utility model is in use, it is moved by the vehicle body 101, and then the road surface to be repaired is covered with the heat-resistant bucket 201 of the device, and then the heating nozzle 208 and the circulating cylinder 207 are started, so that the heating nozzle 208 sprays the combustion material to heat the asphalt road surface framed by the heat-resistant bucket 201. After the asphalt is heated to between one hundred and forty degrees and one hundred and eighty degrees, the angle between the softening claw 202 and the heat-resistant bucket 201 can be adjusted, and then the swing cylinder 109 and the adjusting cylinder 103 are started to rotate the heat-resistant bucket 201 and the heat-resistant bucket 201 relative to the support frame 104. The adjusting cylinder 103 is provided to adjust the distance between the softening claw 202 and the ground to prevent the heat-resistant bucket 201 and the softening claw 202 from being stuck by the ground. At the same time, the swing cylinder 109 can also change the inclination of the heat-resistant bucket 201 to adapt to some special terrains.

[0022] After the asphalt layer on the ground is excavated, the asphalt loosened by the loosening claws 202 can be manually collected. This type of asphalt can be recycled or directly scrapped. After cleaning the road surface that needs to be repaired, the heat-resistant bucket 201 can be used to cover the road surface that needs to be repaired, and then new asphalt is put into the vibrating bucket 106. Then, the handle pointer 107 is manually pulled to rotate the isolation plate 108 in the vibrating bucket 106, so that the asphalt is retained from the diversion port 211 of the vibrating bucket 106, and the asphalt is allowed to enter the place that needs to be repaired in the heat-resistant bucket 201. After the asphalt enters the vibrating bucket 106, the vibrating cylinder 105 can be started to make the vibrating bucket 106 produce a vibration effect, so that the asphalt in the vibrating bucket 106 can flow quickly.
