Description

Technical Field

[0001] The utility model relates to a road seam filling device, belonging to the field of road construction. Background Art

[0002] Road pavement may have cracks due to reasons such as roadbed settlement. Pouring molten asphalt into the cracks on the road pavement is a common treatment method for repairing road pavement cracks. That is, a tube is installed at one end of the asphalt delivery pipe, and a discharge nozzle is installed at one end of the tube. Then, under the action of the pushing mechanism, the molten asphalt enters the tube from the storage tank, and then flows out from the discharge nozzle and is poured into the cracks on the road surface. Because the discharge nozzle is in direct contact with the road surface, the discharge nozzle will generate sliding friction with the ground when moving the discharge nozzle, causing the discharge nozzle to be worn. When the discharge nozzle is severely worn, , it is necessary to separate the discharge nozzle from the tube. The combination of screws and nuts is a common way to connect the discharge nozzle and the tube. When the molten asphalt flows out of the discharge nozzle, the heat in the molten asphalt will increase the temperature of the screws and nuts. Since the screws and nuts are in an exposed state, they are easily oxidized and rusted in an oxygen-rich and high-temperature environment, which makes it difficult to separate the screws and nuts normally in the later stage, increasing the difficulty of replacing the discharge nozzle in the later stage. Therefore, it is necessary to design a road caulking device with a spare disassembly structure for the screws that limit the relative position of the discharge nozzle and the tube. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a road caulking device to solve the problems raised in the above-mentioned background technology. The utility model provides a screw that limits the relative position of the discharge nozzle and the tube with a spare disassembly structure.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical solutions: a road seam filler, including a tube, one end of the tube is provided with a conical bucket, the end of the conical head away from the tube is connected and fixed with a discharge nozzle, the end of the conical bucket away from the discharge nozzle is sleeved with a first ring connected and fixed with the conical bucket, the end of the tube close to the conical bucket is sleeved with a second ring connected and fixed with the tube, the first ring is provided with a plurality of first perforations in an annular manner and equidistantly on one side facing the first ring, and the second ring is provided with a plurality of first perforations in an annular manner and equidistantly on one side facing the first ring. A plurality of second through holes aligned with the first through holes are provided, a support ring with a gap between the second ring and the second ring is provided on the side of the second ring away from the first ring, the support ring is sleeved on the tube and fixedly connected to the tube, a plurality of third through holes aligned with the second through holes are equidistantly arranged in a circular shape on the side of the support ring facing the second ring, a screw is inserted in the channel formed by the first through hole, the second through hole and the third through hole, a nut is threadedly connected to one end of the screw, the nut is arranged on the side of the first ring away from the second ring, and an anti-scalding part is installed on the tube.

[0005] Further, the anti-scalding member includes a first disc. One end of the tube close to the support ring is sleeved with a first disc fixedly connected to the tube. One end of the tube away from the first disc is sleeved with a second disc fixedly connected to the tube. A plurality of blocking rods are annularly and equidistantly installed between the first disc and the second disc, and the blocking rods are arranged parallel to the tube.

[0006] Further, a first blind hole is annularly and equidistantly recessed on the surface of the first disc facing the second disc, and a second blind hole is annularly and equidistantly recessed on the surface of the second disc facing the first disc. Two ends of the blocking rod are respectively inserted into the first through hole and the second through hole.

[0007] Further, an external thread is machined on the outer surface of the end of the tube away from the support ring. One end of the tube with the external thread is threadedly connected with a threaded cap, and a pipe joint is installed on the side of the threaded cap away from the tube.

[0008] Further, ribs are annularly and equidistantly fixed on the outer surface of the threaded cap, and the ribs and the threaded cap are of an integrally formed structure.

[0009] Further, a handle is installed on the outer surface of the tube, and the handle is of a U-shaped structure.

[0010] Advantages of the present utility model:

[0011] 1. When connecting the discharge nozzle and the tube by using the cooperation of a screw and a nut, one end of the screw sequentially passes through the channels formed by the third through hole, the second through hole and the first through hole, and then a nut is screwed on the screw to complete the assembly of the discharge nozzle and the tube. At this time, there is a gap between the head of the screw and the second ring under the support of the support ring. When it is difficult to separate the screw and the nut due to oxidation and rust, the screw can be cut off by using the gap between the support ring and the second ring, so that the screw restricting the relative position of the discharge nozzle and the tube has a spare disassembly structure.

[0012] 2. A plurality of blocking rods are evenly installed between the first disc and the second disc. Then, under the blocking of the blocking rods, it is prevented that personnel directly touch the tube for conveying molten asphalt, the probability of personnel being scalded is reduced, and the safety is improved.
