[0030] In this embodiment, the support frame 1 is the core component of the asphalt pavement crack repair device. The four moving wheels arranged at the bottom of the support frame 1 significantly improve the mobility and operational flexibility of the device, allowing the operator to easily move the device, especially in narrow or complex road environments. The fixed installation of the push handle 10 further enhances the portability and maneuverability of the device. Its U-shaped design not only provides sufficient gripping space to ensure the comfort of the operator, but also the anti-slip cover on the push handle 10 effectively prevents sliding during operation and increases the stability of the operation.

[0031] In a further preferred embodiment of the utility model, the conveying mechanism includes: a screw conveyor 5 fixedly mounted on the support frame 1, the screw conveyor 5 is provided with a feed port 6 and a discharge port 7, the feed port 6 is connected to the bottom of the tank body 2; a sleeve 8 rotatably sleeved on the bottom end of the discharge port 7; an inclined tube 9 arranged at the bottom of the sleeve 8, the inclined tube 9 is integrally formed with the sleeve 8, and the adjustment mechanism is arranged on the inclined tube 9.

[0032] In this embodiment, the careful design of the conveying mechanism ensures efficient and continuous conveying of the repair material from the tank body 2 to the crack repair site. The screw conveyor 5 is fixedly installed on the support frame 1, which not only stabilizes the entire conveying process, but also the feed port 6 provided therein is connected to the bottom of the tank body 2, ensuring that the repair material can smoothly transition from the storage state to the conveying state. The design of the discharge port 7 and the use of the screw conveyor 5 achieve precise control and continuous output of the material.

[0033] The sleeve 8 rotatably sleeved at the bottom of the discharge port 7 and the inclined tube 9 formed integrally with the sleeve 8 at the bottom constitute the key part of the flexible adjustment in the conveying mechanism. This design not only ensures the smooth outflow of the repair material, but also realizes the flexible adjustment of the discharge position of the repair material through the adjustment mechanism set on the inclined tube 9, ensuring that the repair material can be accurately filled into the crack, thereby improving the accuracy and efficiency of the repair.

[0034] This design not only simplifies the operating process and reduces manual intervention, but also significantly improves the efficiency and quality of crack repair, providing strong technical support for the rapid and effective repair of cracks on narrow roads.

[0035] In a further preferred embodiment of the utility model, the adjustment mechanism comprises: a connecting sleeve 11 fixedly sleeved on the oblique tube 9, and a connecting rod 12 extending upward is fixedly mounted on the connecting sleeve 11;

[0036] A screw rod 13 is arranged at the top end of the connecting rod 12, and the diameter of the screw rod 13 is smaller than the diameter of the connecting rod 12, and the screw rod 13 is arranged vertically; a fixing plate 14 is fixedly installed between the two free ends of the push handle 10, and the center of the fixing plate 14 is an arc-shaped curved portion, and an arc track hole 15 is opened in the arc-shaped curved portion. The screw rod 13 passes through the arc track hole 15 and cooperates with the arc track hole slideway, and the center of the arc track hole 15 is on the same vertical line as the center of the sleeve 8; a spherical handle 17 is sleeved on the top end of the screw rod 13, and the spherical handle 17 is manually pushed and pulled to move the screw rod 13 in the arc track hole 15.

[0037] In this embodiment, the design of the adjustment mechanism cleverly combines the principles of mechanical engineering to achieve flexible adjustment of the discharge position of the repair material. The connecting sleeve 11 is fixedly mounted on the inclined tube 9, and the connecting rod 12 connected thereto ensures a stable connection between the adjustment mechanism and the conveying mechanism. The screw rod 13 is arranged at the top of the connecting rod 12, and its diameter is smaller than the connecting rod 12. This design allows the screw rod 13 to move more smoothly in the circular arc track hole 15, while ensuring the stability of the structure. The vertical arrangement of the screw rod 13 and the connecting rod 12 enables the operator to intuitively and accurately control the movement of the screw rod 13 in the circular arc track hole 15 by manually pushing and pulling the ball handle 17, thereby achieving the adjustment of the angle of the inclined tube 9, and ultimately achieving the purpose of accurately controlling the discharge position of the repair material.

[0038] The fixed plate 14 is fixedly installed between the two sides of the push handle 10, and the arc track hole 15 thereon is kept on the same vertical line as the center of the rotation track of the sleeve 8. This design ensures that the movement track of the screw rod 13 matches the rotation track of the sleeve 8, thereby realizing the precise adjustment of the discharge position of the repair material. The operator can flexibly adjust the discharge position of the repair material according to the specific position of the crack by pushing and pulling the ball handle 17. In the process of pushing the device forward and filling the repair material into the gap, even if the gap is not straight and is purely curved, the discharge position of the inclined tube 9 can be adjusted to ensure that the repair material can be accurately filled into the crack, thereby improving the accuracy and efficiency of the repair.

[0039] This design not only simplifies the operation process and improves the efficiency and quality of crack repair, but also provides operators with an intuitive and convenient operation experience, significantly reduces the intensity of manual labor, and has a wide range of practical value and significant economic benefits. In actual applications, the innovative design of this adjustment mechanism can meet the needs of different crack repair scenarios and provide strong technical support for the rapid and effective repair of cracks on narrow roads.

[0040] In a further preferred embodiment of the utility model, a locking knob 16 is threadedly sleeved on the screw rod 13 , and the locking knob 16 is located above the fixing plate 14 and is used to lock the screw rod 13 on the fixing plate 14 .

[0041] In this embodiment, the ingenious design of the locking knob 16 further enhances the stability and accuracy of the adjustment mechanism. The locking knob 16 threadedly sleeved on the screw rod 13 is located above the fixing plate 14. This position design ensures that the operator can easily and quickly rotate the locking knob 16 to firmly fix the screw rod 13 at the desired position after adjusting the discharge position of the repair material, thereby avoiding position displacement due to vibration or external force during the operation process. Therefore, when repairing a straight crack, in the process of pushing the device forward and filling the repair material, it is ensured that the repair material can be continuously and accurately filled into the crack, which significantly improves the efficiency and quality of crack repair.

The fixed installation of the blower 18 on the support frame 1 ensures the stability and reliability of the dust blowing process. The fixed installation of the air outlet of the blower 18 and the connecting pipe 19, and the fixed installation and connection of the bottom end of the connecting pipe 19 and the mounting pipe 20 form an efficient dust blowing channel from the blower 18 to the crack site. The horizontal setting of the mounting pipe 20 and the closed state of both ends ensure that the blown airflow can be concentrated and evenly distributed to multiple air nozzles 21, ensuring the comprehensive coverage and high efficiency of dust blowing. Multiple air nozzles 21 are fixedly installed at the bottom of the mounting pipe 20, connected to the mounting pipe 20, and arranged at equal intervals. This design enables the blown airflow to evenly cover the crack and its surrounding areas, ensuring the uniformity and comprehensiveness of dust blowing, and improving the efficiency and quality of crack cleaning. Each air nozzle 21 is provided with a switch valve, so that the operator can flexibly adjust the opening and closing of each air nozzle 21 according to actual needs.
