Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 This utility model provides a technical solution: a guiding device for emulsified asphalt crack filling, including a traveling vehicle body 1, an asphalt placement box 2 fixed on the top of the traveling vehicle body 1, a rotating wheel 3 rotatably connected to the bottom of the traveling vehicle body 1, a groove 4 provided at one end of the traveling vehicle body 1, the grooves 4 being symmetrically arranged, an anti-deflection mechanism rotatably connected between the two grooves 4, the anti-deflection mechanism including a rotating connecting seat 5 rotatably connected between the grooves 4, a guide member rotatably connected to the end of the rotating connecting seat 5 away from the groove 4, the guide member including a guide plate 6, and a pipe insertion hole 7 provided at the end of the guide plate 6 away from the rotating connecting seat 5.

[0018] In this embodiment, the vehicle body 1 is a KPX battery-powered industrial mobile vehicle with an asphalt placement box 2 mounted on top.

[0019] A telescopic tube 8 is fixed on the side of the asphalt placement box 2. An outlet tube 9 is fixedly connected to the end of the telescopic tube 8 away from the asphalt placement box 2. The outlet tube 9 is fixed inside the fitting insertion hole 7. The telescopic tube 8 is set near the bottom of the asphalt placement box 2. After asphalt is placed inside, it is discharged along the telescopic tube 8 and the outlet tube 9 under the action of gravity. The outlet tube 9 is installed inside the guide plate 6 and can follow the deflection of the guide plate 6.

[0020] The guide plate 6 has connecting plates 10 fixed at both ends. The connecting plates 10 are rotatably connected to the two ends of the rotating connecting seat 5 near the rotating connecting seat 5. Thus, the guide plate 6 itself can be rotated and adjusted. As the vehicle body 1 moves, if the guide plate 6 rotates, it can move along the arc direction, thus allowing asphalt grouting in different arc directions, which is suitable for grouting requirements of various road conditions.

[0021] Specifically, in this embodiment, piston rods 15 are hinged to both sides of the guide plate 6. A cylinder 16 is connected to the end of the piston rod 15 away from the guide plate 6. The end of the cylinder 16 away from the piston rod 15 is hinged to the end of the vehicle body 1. The piston rod 15 is extended and retracted by the cylinder 16. The two cylinders 16 are controlled independently. The empty space on the vehicle body 1 can be used to place the air source of the cylinder 16 without affecting the normal use of the cylinder 16. The cylinder 16 adopts common air source control valves and other control structures. After the cylinder 16 on one side of the guide plate 6 drives the piston rod 15 to extend, the cylinder 16 on the other side controls the piston rod 15 to retract. The rotation angle of the guide plate 6 can be adjusted arbitrarily for convenient use.

[0022] Furthermore, fixing plates 11 are provided at both ends of the groove 4 and fixed to the vehicle body 1 with screws. A vertical rod 12 is fixed between the two fixing plates 11. A support plate 13 is fixed to the end of the rotating connecting seat 5 facing the vertical rod 12. There are two support plates 13. The bottom support plate 13 is set to fit against the fixing plate 11. Both support plates 13 are rotatably connected to the vertical rod 12.

[0023] The vertical rod 12 is fitted with a counterweight lead sleeve 14, and the top of the nested bottom support plate 13 is in contact with the bottom.

[0024] The rotating connecting seat 5 and the guide plate 6 are easy to disassemble and move. At the same time, a lead sleeve is fitted on the outside of the vertical rod 12 to ensure that the guide plate 6 is kept in the lowest position and that the guide plate 6 is highly stable after being placed.

[0025] Furthermore, damping rods 17 are fixed on the inner wall of the groove 4. Several damping rods 17 are evenly spaced along the width of the groove 4. Abutment plates 18 are fixed to the ends of the damping rods 17 away from the groove 4. The abutment plates 18 are set on both sides of the support plate 13. The abutment plates 18 at the upper and lower positions are set corresponding to the positions of the support plate 13. By utilizing the rebound abutment action of the damping rods 17, after the rotating connecting seat 5 deflects, the support plate 13 on the rotating connecting seat 5 can be driven to rotate and reset along the vertical rod 12. In addition, by using the structure of damping rods 17 on both sides, the deflection of the guide plate 6 can be further avoided, the potting route can be maintained, and the potting accuracy can be improved.

[0026] The working principle of this utility model is as follows: A guide plate 6 installed via a rotating connecting seat 5 guides the asphalt filling route. The rotating connecting seat 5 is equipped with damping rods 17 on both sides to further prevent the guide plate 6 from deflecting, maintain the filling route, and improve filling accuracy. At the same time, the guide plate 6 itself can be driven to rotate by a cylinder 16. After the piston rod 15 is extended by the cylinder 16 on one side of the guide plate 6, the piston rod 15 is retracted by the cylinder 16 on the other side. The rotation angle of the guide plate 6 can be adjusted arbitrarily for convenient use.
