[0025] Please see Figure 1-7 This utility model provides a technical solution:
[0026] A small asphalt pavement crack sealing machine includes a base 1, movable support legs 2 fixedly connected to the four corners of the bottom of the base 1, an asphalt tank 3 fixedly connected to the center of the top of the base 1, a movable push handle 4 fixedly connected to one side wall of the asphalt tank 3, a feeding hopper 5 fixedly connected and connected to the top side of the asphalt tank 3, a mixing component 6 provided in the asphalt tank 3, a connecting hose 7 fixedly connected to the center of the bottom of the base 1 and communicating with the inner cavity of the asphalt tank 3, a material pump 8 connected to the bottom end of the connecting hose 7, an anti-clogging component 9 provided on one side of the connecting hose 7, and a flattening component 10 provided on the side of the base 1 near the movable push handle 4.
[0027] The mixing assembly 6 includes a first motor 601 fixedly connected to the center of the top of the asphalt tank 3. A drive shaft 602 is fixedly connected to the output end of the first motor 601. The bottom end of the drive shaft 602 penetrates the top wall of the asphalt tank 3 and extends to the bottom of the inner cavity of the asphalt tank 3. A mixing blade 603 is fixedly connected to the bottom end of the drive shaft 602. The mixing assembly 6 can provide good mixing ability for the asphalt in the asphalt tank 3 to prevent it from clumping and clogging. The anti-clogging assembly 9 includes a drive box 901 fixedly connected to the bottom of the base 1. A second motor 902 is fixedly connected to the front wall of the drive box 901. The output end of the second motor 902 extends into the inner cavity of the drive box 901. An elliptical cam 903 is fixedly connected to the output end of 02. A movable support plate 904, slidably connected to the inner wall of the drive box 901, is located on the side of the cam 903 closest to the connecting hose 7. A limiting groove 905 is formed on one side of the movable support plate 904, and the edge of the cam 903 is positioned within the limiting groove 905. A movable support rod 906 is fixedly connected to the center of the side wall of the movable support plate 904 furthest from the cam 903. One end of the movable support rod 906 penetrates the side wall of the drive box 901 and extends outwards, with a connecting collar 907 fixedly connected to this end. The connecting collar 907 is fitted onto the outside of the connecting hose 7 and fixedly connected to it. The movable support plate 904 and the drive box... A return spring 908 is symmetrically and fixedly connected between the inner sidewalls of 901. The anti-clogging component 9 can drive the connecting hose 7 to reciprocate. Therefore, viscous asphalt is less likely to cause blockage when discharged through the connecting hose 7, thus avoiding affecting the repair effect on the damaged parts of the road surface. The flattening component 10 includes a flattening support plate 1001. A flattening support rod 1002 is fixedly connected to the bottom of the flattening support plate 1001, and a flattening roller 1003 is rotatably connected to the bottom end of the flattening support rod 1002. A connecting frame 1004 matching the specifications of the end of the base 1 is fixedly connected to one side of the flattening support plate 1001. A positioning block 1005 is fixedly connected to the inner sidewall of the connecting frame 1004. A positioning slot 1006 is provided on one side of the base 1, which corresponds to the position of the positioning slot 1005 and matches its specifications. Connecting bolts 1007 are symmetrically passed through the upper and lower ends of the connecting frame 1004.

The connecting screw holes 1008 and the connecting bolts 1007 are positioned and matched in specifications. The flattening component 10 can provide good flattening ability, so it can flatten the asphalt at the repaired part after repair, thereby ensuring the overall repair effect and aesthetics. Moreover, its structure is flexible, so it is easy to disassemble and maintain after damage, so as to ensure that its flattening effect is not affected.
[0028] Workflow: First, power on all electrical appliances and connect them to external controllers. Base 1 provides support and structural stability for the entire system. Movable outriggers 2 provide good support and mobility for base 1. Asphalt tank 3 stores asphalt for road repair. Movable push handle 4, in conjunction with outriggers 2, facilitates the movement of the entire system. Feed hopper 5 adds asphalt to asphalt tank 3. The first motor 601 in the mixing assembly 6 drives the mixing blades 603 via drive shaft 602 to provide good mixing for the asphalt in asphalt tank 3, preventing clumping and blockage. Pump 8 can... The connecting hose 7 extracts asphalt from the asphalt tank 3 and discharges it to the damaged area of the ground for filling and repair. The anti-clogging component 9 can drive the connecting hose 7 to reciprocate, so the viscous asphalt is less likely to cause blockage when discharged through the connecting hose 7, thus avoiding affecting the repair effect on the damaged area of the road. When the pump 8 is pumping and discharging material, the second motor 902 is started. The second motor 902 drives the cam 903 to rotate in the limiting groove 905 on the movable support plate 904 through the output end. After the tip of the cam 903 rotates into the limiting groove 905, it will push the movable support plate 904 to slide towards the connecting hose 7 and reset. Spring 908 compresses the pressure, while movable support plate 904 moves connecting collar 907 via movable support rod 906, ultimately moving connecting hose 7. When the tip of cam 903 rotates to disengage from limit groove 905, the compressive force of return spring 908 decreases, and return spring 908, through its own rebound force, moves movable support plate 904 back to its original position. Simultaneously, it moves connecting hose 7 back to its original position via movable support rod 906 and connecting collar 907, forming a cycle. The flattening support plate 1001 and flattening support rod 1002 in flattening assembly 10 provide good support for flattening roller 1003. The flat roller 1003 can flatten the asphalt at the repaired area after filling and repairing, thereby ensuring the overall repair effect and aesthetics. Its flexible structure makes it easy to disassemble and maintain after damage, so as to ensure that the flattening effect is not affected. When installing the flattening support plate 1001, firstly, the connecting frame 1004 on it is placed on one end of the base 1, and the positioning block 1005 is inserted into the positioning slot 1006 for positioning and locking. At this time, the position of the connecting bolt 1007 corresponds to the position of the connecting screw hole 1008. Finally, the connecting bolt 1007 is screwed into the connecting screw hole 1008. The same method is used for disassembly.
