Description

Technical Field

[0001] The utility model relates to the technical field of paver hoppers, in particular to an adjustable hopper for an asphalt concrete paver. Background Art

[0002] In the field of asphalt concrete road construction, the hopper is an important component of the paver, which is used to store and transport asphalt concrete. However, traditional asphalt concrete paver hoppers often have some problems, such as difficult to control the output volume and uneven paving, which seriously affect the paving quality and efficiency.

[0003] Traditional hoppers usually adopt a fixed discharge port design, which cannot flexibly adjust the discharge volume according to actual needs. In the actual construction process, different projects have different demands for asphalt concrete. If the discharge volume cannot be accurately controlled, it will not only lead to material waste, but also affect the uniformity and flatness of the paving. Secondly, traditional hoppers often cannot achieve uniform material distribution during the paving process. Since the material is affected by gravity and other factors in the hopper, it is easy to accumulate at the discharge port, resulting in uneven distribution of materials on the base surface. This uneven paving will not only affect the performance of the road, but also increase the cost of subsequent maintenance.

[0004] In view of this, the existing structure and defects are studied and improved, and an adjustable hopper for an asphalt concrete paver is provided, in order to achieve a more practical purpose. Utility Model Content

The movable plate 19 is fixedly connected to the slider 20, so the movable plate 19 will also move with the slider 20. , thereby changing the opening size of the discharge port 17, and then controlling the discharge amount. After the asphalt concrete flows out from the discharge port 17, it falls on the gear roller 24 through the discharge port 2 18. When the rotating motor 26 is started, the gear plate 27 is driven to rotate, and the gear track 28 rotates accordingly. The other end of the gear track 28 is movably sleeved on the gear plate 1 25, so the gear plate 1 25 will also rotate accordingly, and then drive the gear roller 24 to rotate. The rotating gear roller 24 evenly spreads the asphalt concrete on the base surface to achieve uniform paving. The driving motor 15 drives the hydraulic rod 14 to adjust the inclination angle of the discharge box 3, thereby changing the flow direction of the asphalt concrete to ensure that it can smoothly enter the gear roller 24.
