At the same time, the utility model also includes a heating mixing device 8, a handheld frame 15, a shoulder strap 24 and an asphalt pump 29, wherein:

[0031] The heating and mixing device 8 comprises an outer cylinder 9, which is fixedly connected to the front of the top of the frame 1, an inner cylinder 10 is arranged inside the outer cylinder 9, and an electric heating wire 11 for heating the inner cylinder 10 is arranged between the outer cylinder 9 and the inner cylinder 10, which is used to stir the asphalt added in the inner cylinder 10 to prevent it from solidifying, and a semicircular top plate 12 is fixedly connected to the top of the inner cylinder 10, and a stirring roller 13 extending into the inner cylinder 10 is inserted on the top plate 12, and a motor 14 is fixedly connected to the top of the stirring roller 13, and the rear end of the motor 14 is connected to the top plate 12 through a motor seat 45; the stirring roller 13 can be driven to stir in the inner cylinder 10 by the drive of the motor 14, which is also used to prevent the asphalt from solidifying or settling. At the top of the inner cylinder 10, there is a semicircular opening outside the top plate 12 for adding asphalt, and when the equipment is running or does not need to add asphalt, a cover plate 32 is arranged on it, and a plurality of air holes 33 are opened on the cover plate 32 for heat dissipation.

[0032] Next, the handheld frame 15 is arranged in the middle of the front end of the frame 1, and a fixed seat 16 fixedly connected to the frame 1 is arranged at the rear of the handheld frame 15. A slot 17 is opened in the middle of the front end of the fixed seat 16, and the handheld frame 15 is inserted into the slot 17. The handheld frame 15 and the fixed seat 16 are connected to each other by a buckle structure 18.

When moving, the strands of asphalt can be smoothed to make it easier to penetrate into the cracks.

[0033] When in use, the user can either fix the spray gun 19 together with the handheld frame 15 on the fixing seat 16, or remove it and repair it manually. The handheld frame 15 together with the spray gun 19 has a certain weight. Therefore, in order to reduce the burden on the staff, the utility model designs the above-mentioned shoulder strap 24, the top and bottom ends of the shoulder strap 24 are fixedly connected with a buffer block 25, and a buffer shaft 26 is inserted on the buffer block 25. The top and bottom of the front end of the handheld frame 15 are provided with a buffer groove 27, and the buffer shaft 26 is fixedly connected in the buffer groove 27. The top and bottom ends of the buffer block 25 are fixedly connected with a spring 28 sleeved on the outside of the buffer shaft 26, and the spring 28 is fixedly connected to the buffer groove 27 away from the end of the buffer block 25; the top of the handheld frame 15 is fixedly connected with a hook 34, The hook 34 is used to hang the shoulder strap 24. Therefore, when the user removes the spray gun 19 together with the hand-held frame 15, the shoulder strap 24 can be put on the body. The spray gun 19 and the hand-held frame 15 are lowered by gravity, pulling the shoulder strap 24 to straighten. At this time, the shoulder strap 24 will give a vertical force to the buffer block 25, which will make the buffer block 25 slide on the buffer shaft 26 in the buffer groove 27 and squeeze the spring 1 28 to deform it. After the spring 1 28 is deformed, it releases the deformation force to offset part of the gravity of the spray gun 19 and the hand-held frame 15. When the user walks, it presents a certain height of repeated displacement. The spring 1 28 is repeatedly deformed, and finally the buffer block 25 moves up and down and tends to be stable, so that the user can repair the crack more stably while reducing the gravity burden brought by the equipment. At the same time, in order to solve the burden of manual hand-holding, the utility model also has a hand-held groove 1 35 at the rear of the top of the hand-held frame 15. A hand-held slot 236 opened on the hand-held frame 15 is provided between the upper and lower buffer slots 27. It is more convenient to hold with both hands.

[0034] In order to provide asphalt to the spray gun 19, the asphalt pump 29 of the utility model is arranged on the side of the fixed seat 16 close to the shoulder strap 24, the asphalt pump 29 is fixedly connected to the frame 1, the inlet of the asphalt pump 29 and the inner tube 10 are connected to each other through an asphalt outlet pipe 1 30, and the outlet of the asphalt pump 29 and the spray gun 19 are connected to each other through an asphalt outlet pipe 2 31.

[0035] To further explain the specific working principle of the present invention, the buckle structure 18 includes a cavity 37 opened at the rear end of the hand-held frame 15 and located below the hand-held slot 1 35. A horizontally arranged slide bar 38 is fixedly connected in the cavity 37. Both ends of the slide bar 38 are slidably connected to sliders 39. The top and bottom ends of the slider 39 are respectively fixedly connected to a pressure rod 40 and a latch 41. The pressure rod 40 and the latch 41 pass through the cavity 37 and extend to the outside of the hand-held frame 15. The portion of the fixing seat 16 located in the slot 17 is provided with a groove 42 for matching with the latch 41. The adjacent sides of the latches 41 on both sides are fixedly connected to springs 2 43. The adjacent sides of the springs 2 43 on both sides are fixedly connected to fixing blocks 44. The fixing blocks 44 are fixedly connected to the bottom of the cavity 37.

[0036] Therefore, when the handheld frame 15 needs to be disassembled or assembled, the user only needs to squeeze the pressure rod 40 to make the slider 39 slide on the slide rod 38, driving the latch 41 away from the groove 42. When it is completely out of the groove 42, the handheld frame 15 and the fixing seat 16 are released from the limit, and the user can remove the handheld frame 15.

[0037] It should be specially noted here that the components described and identified in the text and drawings of the utility model are the key components constituting the utility model, and the remaining non-key components or obvious prior art components, such as screws, nuts and other connectors, and technical features similar to the prior art are not shown.
