[0050] Embodiment 3: A crack filling device for road construction, see Figure 3 and Figure 4 :

[0051] The bottoms of both sides of the stone push plate 503 are connected to the two ends of the connecting strip 504 through positioning components 509 respectively;

[0052] The positioning assembly 509 includes a guide plate 5091, a movable plate 5092, a limit plate 5093 and a positioning block 5095;

[0053] The inner end of the guide plate 5091 is fixed to the bottom of the side end of the pushing stone plate 503; the top of the movable plate 5092 is sleeved on the guide plate 5091; the limit plate 5093 is fixed to the outer end of the guide plate 5091; wherein, two springs 5094 are symmetrically arranged between the movable plate 5092 and the limit plate 5093, and the two ends of the spring 5094 are respectively fixedly connected to the movable plate 5092 and the limit plate 5093, and the elastic coefficient of the spring 5094 is selected and used by the technicians in this profession according to the actual situation; the positioning block 5095 is fixed to the inner bottom of the movable plate 5092; wherein, the positioning block 5095 is inserted and matched with the positioning groove 5041 opened at the end of the connecting strip 504; the positioning block 5095 adopts a triangular structure design, and the inclined surface of the positioning block 5095 faces downward and inward. When the end of the connecting strip 504 moves upward, it contacts the inclined surface of the positioning block 5095, and the positioning block 5095 can be pushed outward, and the connecting strip 504 quickly and conveniently contacts the bottom end of the pushing stone plate 503. A handle 5096 is fixed at the bottom of the outer side of the movable plate 5092, and the handle 5096 is held to facilitate the movement of the movable plate 5092.

[0054] The utility model has the advantage that the rubber strip 505 can be quickly disassembled after excessive wear of the rubber strip 505 by arranging the guide plate 5091, the movable plate 5092, the limit plate 5093, the spring 5094, the positioning block 5095 and the positioning groove 5041, so that the rubber strip 505 can be easily replaced.

[0055] Working principle: When using the device of the utility model, turn the handle 507, the threaded rod 506 rotates and drives the top plate 502 to move down along the guide rod 508, and the push stone plate 503, the connecting strip 504 and the rubber strip 505 move down until the rubber strip 505 touches the ground. The glue for sealing the seams is added to the material box 2, and the staff moves the cart 1 through the cracks in the road. The tips and inclined surfaces of the push stone plate 503, the connecting strip 504 and the rubber strip 505 contact the small particles when moving, and the small particles can be pushed to both sides to reduce the particles in the cracks. The delivery pump on the cart 1 pumps the glue in the material box 2 out from the discharge pipe, and the glue is discharged from the opened discharge valve 3 and falls on the cracks in the road.

[0056] When the bottom of the rubber strip 505 is worn, the handle 507 is rotated to move the stone push plate 503, the connecting strip 504 and the rubber strip 505 downward, and the bottom of the rubber strip 505 is always in contact with the ground when in use; when not in use, the handle 507 is rotated in the opposite direction to raise the stone push plate 503, the connecting strip 504 and the rubber strip 505, and the rubber strip 505 is not in contact with the ground, thereby protecting the rubber strip 505.

[0057] After the rubber strip 505 is excessively worn, the handle 5096 is held to pull the movable plate 5092 outward, and the movable plate 5092 moves outward along the guide plate 5091, and the spring 5094 is further compressed until the positioning block 5095 leaves the positioning groove 5041. The connecting strip 504 and the rubber strip 505 are removed, and the new connecting strip 504 and the rubber strip 505 are installed to the bottom end of the pushing stone plate 503. When the end of the connecting strip 504 moves upward, it contacts the inclined surface of the positioning block 5095, and the positioning block 5095 can be pushed outward until the connecting strip 504 contacts the bottom end of the pushing stone plate 503, and the positioning block 5095 is no longer pushed. Under the action of the spring 5094, the movable plate 5092 drives the positioning block 5095 to move back, and the positioning block 5095 is inserted into the positioning groove 5041 to position the connecting strip 504 and the rubber strip 505.

[0058] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes.
