Description

Technical Field

[0001] This utility model relates to the technical field of asphalt compaction equipment, and in particular to an asphalt paving joint compaction device. Background Technology

[0002] Asphalt is a widely used pavement structural binder in road engineering. When mixed with mineral materials of different compositions in a certain proportion, it forms an asphalt pavement with different structures. After paving, the asphalt mixture in a loose state needs to be rolled and compacted to ensure the density and smoothness of the asphalt pavement.

[0003] Patent CN220183750U discloses a hot roller for municipal asphalt road construction. In use, the scraper and nozzle work together: the scraper cleans the roller, and the nozzle sprays a release agent onto the outer wall of the roller, reducing the probability of asphalt adhering to it. Furthermore, the scraper consists of a plate and removable, replaceable blades, allowing for quick maintenance and replacement by treating the blades as consumables. However, this device has the following drawbacks: when the roller is in motion but not in use, the blades remain in contact with it. Even though the blades are removable and replaceable, this leads to unnecessary wear, shortening their actual lifespan and increasing the frequency of replacement.

[0004] Therefore, optimizing the equipment structure so that the scraper can disengage from the road compaction structure when it is not in operation, thereby avoiding unnecessary wear and reducing the replacement frequency, has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The present invention aims to provide an asphalt paving joint compaction device to overcome the above-mentioned shortcomings.

[0006] To achieve the above objectives, the technical solution of this utility model is: an asphalt paving joint compaction device, comprising:

[0007] A support frame, with a rolling roller rotatably connected inside;

[0008] The mounting plate is arranged on the support frame, and at least one fixing sleeve is connected to its upper end in the horizontal direction. The fixing sleeve is provided with an external thread section, and the fixing sleeve is provided with two guide grooves opposite each other in the vertical direction.

[0010] The first nut, the external threaded section is threaded with at least two first nuts, the first nuts arranged on both sides of the guide block define its position in the guide groove.

[0011] Furthermore, a connecting plate is provided between the support rod and the scraper. The connecting plate is located on the left side of the mounting plate. One end of the connecting plate is fixedly connected to one end of the support rod. The other end of the connecting plate is provided with a sliding groove along the width direction. The sliding groove is slidably connected to the scraper. A plurality of first fasteners are provided on the connecting plate. The first fasteners penetrate the connecting plate vertically and are connected to the scraper.

[0012] Furthermore, a placement plate is provided on the support frame, and the placement plate is arranged opposite to the mounting plate. A limiting ring is fixedly connected to the placement plate, and the limiting ring is sleeved around the periphery of the material barrel.

The water outlet pipe connected to the water pump passes through the upper end of the support frame and is connected to the spray disc, and the spray disc faces the rolling wheel.

[0013] Furthermore, the spray disc is square and has the same width as the rolling wheel.

[0014] Furthermore, the upper end of the material bucket is provided with a through hole, and the motor is detachably connected to the upper end of the material bucket through a second fastener. The output shaft of the motor passes through the through hole and is connected to the rotating shaft for transmission. The rotating shaft is arranged inside the material bucket.

[0015] Furthermore, a fixed stirring assembly is fixedly connected to the lower end of the rotating shaft. The fixed stirring assembly is the same width as the through hole. The fixed stirring assembly includes a second fixing ring and a second stirring blade. The second fixing ring is fixedly connected to the lower end of the rotating shaft, and at least one second stirring blade is fixedly connected to the side wall of the second fixing ring.

[0016] Furthermore, a connecting sleeve is provided between the output shaft of the motor and the rotating shaft.

[0019] Compared with the prior art, this utility model has at least the following advantages: When in use, the operator rotates the first nut on the external thread of the fixed sleeve, and the first nuts on the left and right sides of the guide block will drive the support rod to move horizontally along the guide groove of the fixed sleeve, thereby driving the support rod to move and making the scraper abut against the outer surface of the rolling wheel.

[0020] When the equipment is in a non-operating moving state, rotating the first nut in the reverse direction causes the first nuts on the left and right sides of the guide block to move the support rod in the opposite direction along the guide groove of the fixed sleeve, moving the scraper away from the surface of the compaction wheel. At this time, even if the compaction wheel moves, the scraper will not contact the wheel body, avoiding unnecessary friction in the non-operating state and reducing scraper wear. By adjusting the position of the first nut, selective contact between the scraper and the compaction wheel is achieved, solving the wear problem caused by continuous scraper contact when not in operation in existing designs, and reducing the scraper replacement frequency.
