[0016] Please see Figure 1-5 This utility model provides a device for repairing cracks in a residential road surface, comprising: an outer shell 1, with adjustable push rods 4 installed on both sides of the outer shell 1, a cleaning component provided on one side along the moving direction inside the outer shell 1, and an inner box 2 provided on the other side, the inner box 2 extending through the upper and lower end faces of the outer shell 1, and a plurality of pressure rollers 3 rotatably provided at the lower end of the inner box 2 for compacting the repaired ground surface; The inner box 2 has a heat-insulating storage chamber 5 inside, which contains liquid repair material. The storage chamber 5 has a feed inlet on one side of the top of the storage chamber 5 and a material extraction component 6 on the other side of the top of the storage chamber 5. The material extraction component 6 is used to extract the liquid repair material to repair road cracks. The bottom of the inner box 2 has material leveling structures on both sides, which are used to level the laid material during the movement of the device.

[0017] It should be explained that during use, the device is moved to the target position by pushing the push rod 4, and then the cleaning component is activated to clean the crack that needs to be repaired. After the crack is cleaned, the material extraction component 6 in the inner box 2 is activated to extract the liquid repair material stored in the storage chamber 5. The liquid repair material is accurately delivered to the cleaned crack by holding the output end of the material extraction component 6. Afterwards, the staff judges the asphalt temperature to be dropped to a suitable temperature based on experience, and then the material in the area to be repaired is leveled by the material leveling structure. Finally, the material is flattened by the pressure roller 3 by pushing the device by the push rod 4.

[0018] The liquid repair material is asphalt. The storage chamber 5 is used to store high-temperature asphalt. The inner wall of the storage chamber 5 is made of heat-insulating material and equipped with a temperature control system to ensure that the asphalt in the storage chamber 5 is always kept at a suitable temperature to meet the repair requirements. The pressure roller 3 is filled with counterweight material, which is used for both the movement of the device and the compaction of the repair material.

[0019] By integrating the cleaning components, pressure rollers 3, material extraction components 6, and material distribution structure, the number of times equipment or materials are handled is reduced, making it suitable for narrow and scattered cracks in residential areas, improving repair efficiency, and reducing the labor intensity of repairs.

[0020] Furthermore, the material equalization structure includes: a material equalization plate 7 fixed at the bottom of the inner box 2, the material equalization plate 7 being located on both sides of the device moving in the direction of movement and on the outside of each of the pressure rollers 3, the lower end of the material equalization plate 7 being provided with a protruding end 8 along its extension direction, each of the material equalization plates 7 being provided with an inclined surface 9 on the side away from the pressure roller 3, and the lower end of the protruding end 8 being provided with a plurality of openings 10 evenly distributed.

[0021] Specifically, when leveling the repair material, the inclined plane 9 compresses and pushes the repaired asphalt to level it and reach a suitable height, facilitating the subsequent compaction operation of the repaired asphalt by the pressure roller 3. The opening 10 divides the concentrated asphalt injection into multiple fine streams, preventing material accumulation or loss in certain areas and resulting in a more uniform distribution of asphalt.

[0022] Furthermore, the protruding end 8 of the uniform material plate 7 is 0.5~0.8cm higher than the bottom end of the pressure roller 3 to avoid a large height difference between the repair material and the original road surface after compaction.

[0023] Furthermore, the material extraction assembly 6 includes: a pump body 11 installed on the top of the inner box 2, an inlet pipe 12 installed at the input end of the pump body 11, the inlet pipe 12 extending to the bottom of the inner box 2, and an outlet pipe 13 installed at the output end of the pump body 11.

[0024] The pump body 11 draws material from the storage chamber 5 through the feed pipe 12 at the input end. After being pressurized by the pump body 11, the material is transported to the crack through the discharge pipe 13 at the output end. The pressurized delivery by the pump body 11 ensures that the material can fully fill the deep crack, avoiding the "void" problem caused by manual pouring. Both the feed pipe 12 and the discharge pipe 13 are made of high-temperature resistant and heat-insulating materials.

[0025] Furthermore, the cleaning component includes: a mounting cylinder 14, a lifting drive component is provided at the top of the mounting cylinder 14 for driving the mounting cylinder 14 to move vertically, a limiting component is provided between the inner wall of the outer shell 1 and the outer wall of the mounting cylinder 14 for limiting the rotation of the mounting cylinder 14 during the lifting process, a rotating drive component 15 is installed downward inside the mounting cylinder 14, a connecting rod 16 is coaxially mounted at the output end of the rotating drive component 15, a disc body 17 is fixed at the bottom end of the connecting rod 16, and brushes 18 are evenly distributed at the lower end of the disc body 17.

[0026] It should be explained that when cleaning ground cracks is required, the cleaning component is moved to the target area, and the rotating drive 15 is activated, which drives the disc 17 and the brush 18 to rotate, cleaning the ground cracks and surrounding dust, pebbles and other debris. When cleaning cracks, for small cracks (width less than 1cm), only the depth that the brush 18 can clean is 0.5~1cm. For wider cracks (width greater than 1cm), manual grooving can be performed to improve the repair effect. During the cleaning process, the limiting component between the outer shell 1 and the mounting cylinder 14 can prevent the mounting cylinder 14 from shifting, ensuring that the brush 18 is always aligned with the crack area.

[0027] After cleaning, the lifting drive unit raises the mounting cylinder 14 to prevent the brush 18 from coming into contact with the repair material and causing contamination.

[0028] Furthermore, an adjusting screw 19 is threadedly connected to the top of the outer casing 1. The adjusting screw 19 passes through the top of the outer casing 1 and is coaxially and rotatably limited to the top of the mounting cylinder 14. A handwheel is installed at the top of the adjusting screw 19.

[0029] In other words, when cleaning cracks in the ground, the height of the cleaning component can be adjusted by turning the handwheel to drive the adjusting screw 19, thereby changing the contact pressure between the brush 18 and the ground to adapt to the cleaning of cracks in different states and improve the cleaning effect. At the same time, the coaxial rotation limit design of the adjusting screw 19 ensures that the mounting cylinder 14 rises and falls smoothly, and avoids the brush 18 from shifting and affecting the cleaning accuracy.

[0030] Furthermore, a mounting cavity is coaxially formed in the middle of the disk body 17, and a connector 20 is provided at the bottom of the mounting cavity. The connector 20 passes through the mounting cavity and is fixedly connected to the connecting rod 16. The top periphery of the disc body 17 is evenly provided with a number of insertion rods 21, and the bottom of the mounting cylinder 14 is provided with a number of insertion holes 22 corresponding to the insertion rods 21, and the insertion rods 21 are inserted into the insertion holes 22.

[0031] Specifically, when installing the disc body 17, the connector 20 at the bottom of the mounting cavity in the middle of the disc body 17 is fixed to the connecting rod 16 to ensure that the disc body 17 and the connecting rod 16 rotate coaxially; at the same time, several insert rods 21 on the top periphery of the disc body 17 are aligned with the insertion holes 22 at the bottom of the mounting cylinder 14 and inserted to form a circumferential limit, preventing the disc body 17 from shaking when rotating and improving cleaning stability; when it is necessary to replace the brush 18, the connector 20 is removed, the disc body 17 is lifted upward to disengage the insert rods 21 from the insertion holes 22, and the disc body 17 can be removed for maintenance.

[0032] Furthermore, the limiting component includes a plurality of limiting tracks 23 longitudinally fixed to the inner wall of the outer shell 1, and a plurality of sliders 24 corresponding to each of the limiting tracks 23 are provided on the outer wall of the mounting cylinder 14. The sliders 24 are slidably disposed within the limiting tracks 23. By limiting the sliding of the limiting tracks 23 and the sliders 24, the stability of the mounting cylinder 14 can be ensured even when the rotary drive component 15 rotates at high speed.

[0033] Furthermore, the push rod 4 includes a U-shaped push rod 25, the two ends of which are respectively hinged to the two sides of the outer shell 1. A locking member 26 is provided at the hinge point between the push rod 4 and the outer shell 1. A stop bar 27 is provided at the front and rear of both sides of the outer shell 1. The stop bar 27 is used to limit the U-shaped push rod 25.

[0034] Specifically, when adjusting the angle of the U-shaped push rod 25, loosen the locking piece 26 at the hinge between the push rod 4 and the outer shell 1, rotate the U-shaped push rod 25 to a suitable angle, and the stop bar 27 is used to limit the rotation range of the U-shaped push rod 25 (0~60°); after determining the angle, tighten the locking piece 26 to fix the U-shaped push rod 25, and the operator holds the middle of the U-shaped push rod 25 with both hands to push the device to move.

[0035] In practice, liquid asphalt repair material is injected into the storage chamber 5. The height of the cleaning component is adjusted by handwheel so that the brush 18 makes slight contact with the road surface. The locking part 26 is loosened, the U-shaped push rod 25 is adjusted to a suitable height, and the locking part 26 is tightened. Then, the rotary drive 15 is started to push the device along the crack. The brush 18 rotates at high speed to remove dust and small stones in the crack. The limiting rail 23 ensures that the brush 18 is always aligned with the crack. Then, the device is moved to the side of the crack, the pump body 11 is started, and asphalt material is delivered to the crack through the discharge pipe 13. Afterward, the staff judges the asphalt temperature based on experience and after it drops to a suitable temperature, the excess material is dispersed by the inclined surface 9 of the front uniform plate 7. The pressure roller 3 moves with the device to compact and level the asphalt. After completion, the equipment is turned off, and the residual material in the discharge pipe 13 is cleaned for the next use.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
