[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model effectively solves the dripping problem of traditional crack filling machines through an innovative crack filling head angle adjustment mechanism. After the crack filling is completed, the operator can turn the handle to rotate the rotating rod, so that the discharge port of the crack filling head faces upward, avoiding residual material dripping onto the ground. This reduces material waste and eliminates safety hazards. At the same time, the threaded connection design between the threaded rod and the fixing hole ensures the stability of the crack filling head after angle adjustment, eliminating the need for frequent manual fixing and significantly improving the ease of operation. In addition, the handle on the top of the mobile vehicle and the design of double moving wheels enhance the mobility of the equipment, making it easy to quickly locate the crack in complex road conditions and improving construction efficiency.

[0017] 2. This utility model achieves precise monitoring and regulation of material temperature and pressure inside the heating tank through the integrated control of an electric heating mantle, thermocouples, and a pressure gauge. The thermocouples provide real-time temperature data feedback to the control system, dynamically adjusting the power of the electric heating mantle to ensure the material is always in the optimal melting state. The pressure gauge prevents excessive pressure inside the heating tank, avoiding safety accidents caused by overpressure. In addition, the automated design of the cleaning process significantly reduces manual maintenance time and material residue issues, extending the equipment's service life. The modular overall structure also facilitates component disassembly and maintenance, further reducing maintenance costs. These improvements collectively enhance the equipment's reliability, safety, and long-term operating efficiency. Attached Figure Description

[0023] Please see Figures 1-4 A road repair material crack sealing machine includes a mobile vehicle 1. A heating tank 4 and a delivery pump 12 are installed on the top of the mobile vehicle 1. The inlet end of the delivery pump 12 is connected to the outlet end of the heating tank 4. The outlet end of the delivery pump 12 is connected to a crack sealing assembly 2. The crack sealing assembly 2 includes a connecting pipe 201. One end of the connecting pipe 201 is connected to a first valve 209, and the other end of the connecting pipe 201 is connected to a second valve 211. The outlet end of the first valve 209 is connected to a flexible hose 205, and the outlet end of the flexible hose 205 is connected to a crack sealing head 204.

[0024] Furthermore, a rotating rod 203 is fixedly connected to the surface of the filling head 204. One end of the rotating rod 203 is rotatably connected to an adjusting disc 202. A fixing hole 206 is provided around the adjusting disc 202. A rotating handle 207 is fixedly connected to the surface of the rotating rod 203. A threaded rod 208 is installed on the rotating handle 207. The threaded rod 208 is threadedly connected to the fixing hole 206.

[0025] Furthermore, a handle 9 is fixedly installed on the top of the mobile vehicle 1.

[0026] Furthermore, a protective cover 5 is installed on the surface of the heating tank 4, and the protective cover 5 is fixedly installed on the top of the mobile vehicle 1.

[0027] Furthermore, the surface of the protective cover 5 is equipped with a first moving wheel 3, and the bottom of the moving vehicle 1 is equipped with a second moving wheel 10.

[0028] Furthermore, an electric heating jacket 8 is installed on the surface of the heating tank 4, and a thermocouple 11 is installed on the surface of the protective cover 5. The detection end of the thermocouple 11 extends into the inner cavity of the heating tank 4.

[0029] Furthermore, a cover 7 is threaded onto the top of the heating tank 4, and a pressure gauge 6 is fixedly installed on the top of the cover 7. The detection end of the pressure gauge 6 extends into the inner cavity of the heating tank 4.

[0030] Furthermore, the feed end of the second valve 211 is connected to a conveying pipe 212, which is connected to the discharge end of the conveying pump 12.

[0031] Furthermore, a fixing bracket 210 is fixedly sleeved on the surface of the connecting pipe 201, and the fixing bracket 210 is fixedly installed on the surface of the protective cover 5.

[0032] Furthermore, one end of the adjustment plate 202 is fixedly connected to a mounting base 213, which is fixedly mounted on the surface of the protective cover 5.

[0033] When modifying the road surface, the repair material is placed inside the heating tank 4 beforehand. After placement, the cover 7 is installed on top of the heating tank 4. The material inside the heating tank 4 is heated and melted by the electric heating mantle 8. Thermocouple 11 detects the material temperature, and the detected data is transmitted to the control system. The control system controls the heating power of the electric heating mantle 8 according to the preset temperature and the detected temperature, so that the material reaches the preset melting temperature. Pressure gauge 6 detects the pressure inside the heating tank 4. When the pressure is too high, heating is stopped to avoid safety accidents. The delivery pump 12 draws the repair material from the bottom of the heating tank 4 and then delivers it to the inside of the crack filling assembly 2. The crack filling assembly 2 injects the repair material into the cracks in the road surface to repair and maintain the road surface. When it is necessary to repair cracks in different locations, the mobile vehicle 1 is moved by pushing the handle 9. The mobile vehicle 1 moves on the ground by the first moving wheel 3 and the second moving wheel 10. During the movement, the staff adjusts the angle and position of the crack filling by pushing the crack filling machine and swinging the crack filling machine.

[0034] During the operation of the crack filling component 2, the delivery pump 12 delivers the repair material into the delivery pipe 212. The second valve 211 adjusts the material delivery volume. After adjustment, the repair material enters the hose 205 through the connecting pipe 201 and the first valve 209. The hose 205 discharges the repair material through the crack filling head 204, allowing the repair material to enter the crack. When it is necessary to stop the crack filling, the operator first closes the first valve 209 to prevent the material from continuing to enter the hose 205. Then, after the material inside the hose 205 and the crack filling head 204 is emptied, the handle 207 is turned downwards, which drives the rotating rod 20. 3. Rotate downwards to make the filling head 204 rotate upwards, placing the discharge port of the filling head 204 upwards to prevent residual material inside the first valve 209 and hose 205 from dripping onto the ground. After rotation, insert the threaded rod 208 into the handle 207 and screw it into the fixing hole 206 to fix the filling head 204. When filling is needed, reset the filling head 204. After filling, clean the inside of the heating tank 4 and use the delivery pump 12 to extract the cleaning agent inside the heating tank 4 and deliver the cleaning agent to the inside of the filling assembly 2 to clean the residual repair material inside the filling assembly 2.
