Description

Technical Field

[0001] The utility model relates to the technical field of pavers, in particular to a material cleaning device for pavers. Background Art

[0002] A paver is a special equipment used to spread the mixed material evenly on the leveled roadbed or base. During the paver paving process, the mixed material is poured into the paver hopper from a dump truck, and then transported by a scraper and a spiral spreader to be evenly spread horizontally on the roadbed or base. Finally, it is preliminarily compacted and shaped to form a paving layer with a certain width, thickness and shape. Most of the existing pavers are manually cleared from the hopper, which wastes a lot of time and energy and is inconvenient for the operator.

[0003] After searching, it is found that the Chinese publicly authorized patent "A material cleaning device for a paver" with the publication number "CN219930637U" is provided with a second fixed block, a third fixed block, a first rotating block, a second rotating block and an electric telescopic rod. When there is material accumulation inside the hopper carrier plate, one end of the electric telescopic rod extends. At this time, the first rotating block and the second rotating block rotate inside the second fixed block and the third fixed block respectively, thereby driving the hopper carrier plate to rotate, making the hopper carrier plate in an inclined state, and the accumulated material slides down due to gravity.

[0004] In the above case, the hopper carrier plate will drive the slide bar to slide in the slide groove when it rotates, but this device needs to add high-temperature asphalt to the hopper carrier plate. The asphalt will enter the slide groove and block it. The slide bar cannot slide smoothly in the slide groove, which may easily cause the hopper carrier plate to be unable to rotate smoothly.

[0005] Therefore, a material cleaning device for a paver is proposed to solve the above problems. Utility Model Content

Crushing knives are fixedly connected to both sides of the hopper carrier plate, and the crushing knife is located between the two arc rods. When the hopper carrier plate rotates, it will slide on the surface of the arc rod through the arc hole and the scraper piece. At this time, the residual material adhering to the surface of the arc rod will be scraped off by the arc tube-shaped scraper piece. At the same time, when the hopper carrier plate rotates, it will drive the crushing knife to move between the two arc rods, and the crushing knife will break the accumulated material between the two arc rods. Compared with the comparative case, the hopper carrier plate in this device rotates more smoothly, and there will be no situation where the hopper carrier plate is blocked by accumulated material and difficult to rotate.

The crushing knife will break the accumulated material between the two arc rods. Compared with the comparative case, the hopper carrier plate in this device rotates more smoothly, and there will be no situation where the hopper carrier plate is difficult to rotate due to being blocked by the accumulated material;

[0014] 2. At the same time, start the motor on the side of the hopper carrier plate where there is no material accumulation. The output shaft of the motor drives the worm wheel to rotate through the worm meshing, and then the worm wheel drives the rotating frame to rotate. When the rotating frame rotates, the accumulated material in the hopper carrier plate will be moved. While ensuring the cleaning effect of the accumulated material in the comparison case, this solution sets the motor on the side of the hopper carrier plate that is not exposed to materials such as asphalt, thereby avoiding the influence of high-temperature asphalt on the motor and reducing the probability of motor damage.
