[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0020] Depend on Figures 1 to 5 It is known that an asphalt crack sealing machine includes a machine body 1, a push handle 11 on the side of the machine body 1, multiple traveling wheels 10 at the bottom of the machine body 1, a material bucket 2 on the top of the machine body 1, a material inlet 14 on one side of the top of the material bucket 2, a stirring rod 3 inside the material bucket 2, a motor 12 on the top of the material bucket 2, the motor 12 drives the stirring rod 3 to rotate, a spiral plate 13 is provided on the outside of the stirring rod 3, the material bucket 2 is connected to a crack sealing mechanism via an asphalt pump 4, the crack sealing mechanism includes a rotating shaft 5 rotatably mounted on the machine body 1, a turntable 6 at the bottom of the rotating shaft 5, multiple through holes 7 on the turntable 6, and crack sealing heads 8 of different specifications at the bottom of the multiple through holes 7, and a discharge port on the machine body 1. After the turntable 6 rotates, the multiple through holes 7 can connect with the discharge port in sequence, forming a structure in which the material bucket 2 connects with crack sealing heads 8 of different specifications.

[0021] In practical use, this utility model

[0022] Asphalt is poured into the material bucket 2 through the feed inlet 14. The motor 12 is started and the stirring rod 3 is used to stir the asphalt to prevent it from solidifying. When the crack filling position is reached, the crack filling mechanism is adjusted so that the crack filling head 8 matches the crack size. Then the asphalt pump 4 is started to extract the asphalt and pour it into the crack from the crack filling head 8 to complete the crack filling construction.

[0023] In this equipment, a spiral plate 13 is provided on the outside of the stirring rod 3. When it rotates, it can drive the asphalt upward, so that the asphalt located at the bottom of the material bucket 2 can flow upward and avoid solidifying at the bottom of the material bucket 2.

[0024] The bottom of the crack sealing mechanism is equipped with multiple crack sealing heads 8, which can be quickly switched according to the size and specifications of the crack to adjust the amount of asphalt injection, making it easier to control and thus better complete the crack sealing.

[0025] The discharge port is connected to the asphalt pump 4 via the first pipe 15. The first pipe 15 is provided with a second pipe 16 on its side. The second pipe 16 is connected to a collar 17. The other side of the collar 17 is connected to a handheld nozzle 18. The collar 17 is fitted on the outside of the rotating shaft 5. The inside of the collar 17 is connected to the second pipe 16 and the handheld nozzle 18. A cross hole 19 is opened on the rotating shaft 5. The axis of the cross hole 19 is not in the same plane as the axis of the through hole 7.

[0026] To further facilitate use, a second pipe 16 is connected to the side of the first pipe 15. The handheld nozzle 18 at the end of the second pipe 16 can perform manual grouting, allowing grouting operations to be performed in areas that the machine body 1 cannot reach, thus expanding the construction range.

[0027] When using the crack filling head 8 for crack filling, the through hole 7 on the turntable 6 corresponds to the discharge port. At this time, the cross hole 19 on the rotating shaft 5 does not coincide with the axis of the second pipe 16, which can block the connection between the second pipe 16 and the handheld nozzle 18. Crack filling is carried out only through the crack filling head 8. When using the handheld nozzle 18 for crack filling, the cross hole 19 is aligned with the axis of the second pipe 16. At this time, the turntable 6 blocks the discharge port, and the asphalt is discharged from the handheld nozzle 18 only after passing through the second pipe 16.

[0028] To achieve the positioning of the rotating shaft 5, multiple limiting holes 20 are evenly distributed above the collar 17. A limiting plate 21 is provided on the outside of the rotating shaft 5. A limiting rod 22 that cooperates with the limiting holes 20 is passed through the limiting plate 21. A spring 23 is sleeved on the limiting rod 22. The spring 23 pushes the limiting rod 22 downward, and the limiting rod 22 is inserted into the limiting hole 20 to fix the position of the rotating shaft 5 and the collar 17. At this time, the asphalt injection pipeline is fixed and unique, and the asphalt can be discharged from the designated outlet, which is convenient for crack filling construction. When it is necessary to switch the crack filling head 8, the limiting rod 22 is pulled upward so that the rotating shaft 5 can rotate. When switching to the corresponding crack filling head 8 or handheld nozzle 18, the limiting rod 22 is released, and the spring 23 pushes the limiting rod 22 downward into the limiting hole 20 to form a limit.

[0029] Compared with the prior art, this utility model has the following advantages: the crack filling mechanism with multiple filling heads can quickly switch between different specifications of filling heads so that the amount of asphalt sprayed is matched with the crack, thereby better realizing the crack filling construction.
