[0015] The present invention will be described in detail below with reference to the accompanying drawings. Figure 1 As shown, an asphalt grouting device for a road maintenance vehicle includes a mobile chassis 1, an asphalt tank 3 is fixedly mounted on the upper part of the mobile chassis 1, an electric heater 2 is detachably mounted on the outside of the asphalt tank 3, an asphalt pump 4, an air pump 5 and a heating seat assembly 6 are also mounted on the mobile chassis 1, the inlet of the asphalt pump 4 is connected to the outlet pipeline of the asphalt tank 3, and an asphalt delivery hose 7 is provided at the outlet of the asphalt pump 4.

[0016] In this embodiment, combined with the Figure 2 As shown, a pipe joint 71 is installed between the asphalt delivery hose 7 and the outlet of the asphalt pump 4, and a discharge head 72 is installed at the other end of the asphalt delivery hose 7. The heating seat assembly 6 includes a base 61, and a top cover 62 is detachably installed on the upper part of the base 61. Semi-annular heaters 63 are installed in the groove opened on the upper part of the base 61 and the lower part of the top cover 62. After the grouting is completed, the user removes the pipe joint 71 from the asphalt pump 4 and installs it to the air outlet of the air pump 5. The air pump 5 blows air into the asphalt delivery hose 7 to blow out the residual asphalt in the asphalt delivery hose 7 to prevent the asphalt from solidifying in the asphalt delivery hose 7.

[0017] In this embodiment, specifically, the base 61 is fixedly installed on the upper part of the mobile chassis 1 .

[0018] In this embodiment, specifically, the pipe joint 71 is adapted to the air outlet of the air pump 5 .

[0019] How it works

[0020] In the present utility model, the user fixes the mobile chassis 1 to an external road maintenance vehicle through an external connecting piece. The road maintenance vehicle drives the mobile chassis 1 to move, connects the asphalt pump 4 to an external power source, and the asphalt pump 4 squeezes the asphalt in the asphalt storage tank 3 through the asphalt delivery hose 7. The user clamps the discharge head 72 with an external clamping tool and moves it to the cracks in the road surface to achieve the grouting operation.

[0021] Utilizing the technical solution described in the present invention, or those skilled in the art designing similar technical solutions inspired by the technical solution of the present invention to achieve the above-mentioned technical effects, all fall within the scope of protection of the present invention.
