Description

Technical Field

[0001] This utility model relates to a road paving device, belonging to the field of road administration technology. Background Technology

[0002] Road paving equipment is specialized machinery used to efficiently and precisely lay materials such as concrete and asphalt onto road surfaces. The type and function of this equipment vary depending on the construction needs and scale. Using a screw conveyor to spread the paving material across the width of the road is a common paving structure; however, current road paving equipment using this structure has a low level of automation and produces poor road surface quality. Utility Model Content

[0003] The purpose of this invention is to solve the technical problems of low automation and poor road surface quality in the existing technology, and to provide a road paving device.

[0004] This utility model is achieved through the following technical solution: The invention relates to a road paving equipment, comprising a tracked power vehicle equipped with a feed hopper, a paving mechanism for spreading paving material onto the road surface installed at the rear of the tracked power vehicle, a rear support installed at the rear of the tracked power vehicle, the paving mechanism being connected to the rear support via a lifting structure, the paving mechanism including two side plates connected together by a cross brace, a pressure plate between the lower parts of the two side plates, a vertical plate at the front end of the pressure plate, and a row of several vibrating rods installed at the front end of the vertical plate. The rear support has two screw conveyors and a hydraulic motor installed at the rear end. The hydraulic motor is connected to the inner end of the two screw conveyors through a coaxial forward and reverse transmission mechanism.

[0005] A tracked power vehicle provides power to the paving mechanism. Paving materials such as concrete and asphalt are fed into the hopper and fall to the ground. A hydraulic motor drives two screw conveyors to rotate in both directions via a forward and reverse transmission mechanism. Under the action of the two screw conveyors, the paving material is spread out in the width of the road surface. A row of vibrating rods then vibrates the paving material to remove air and slurry. Finally, a pressure plate levels and compacts the paving material. This invention features a high degree of automation and produces higher quality road surfaces.

[0006] Further optimization involves placing the feed hopper at the front of the tracked power vehicle and installing sloping guide plates at the rear outlet. Paving materials such as concrete and asphalt are fed into the feed hopper, with the guide plates positioned close to the screw conveyor at their ends, effectively guiding and limiting the paving materials.

[0007] Further optimization involves mounting two hydraulic cylinders (secondary cylinders) on the rear support. The lower ends of these cylinders are connected to side supports, one end of which is connected to a cross brace, and the other end is hinged to the side of the tracked vehicle. The height of the tiling mechanism can be adjusted using these two hydraulic cylinders, which helps improve environmental adaptability.

[0008] Further optimization involves installing a limit post and a hydraulic cylinder on the side of the tracked power vehicle. A connecting plate is hinged to the front end of the side bracket, extending into the limit post on the side of the tracked power vehicle. Two limit wheels are installed on the limit post, and the front end of the connecting plate is hinged to the hydraulic cylinder. The hydraulic cylinders on the same side work together to adjust the paving mechanism in the left and right directions to adapt to the inclination in the width direction of the road surface.

[0009] Further preferred, the bottom of the cross brace is fixed with two rows of support plates, and the support plates are equipped with screws. The screws are equipped with two nuts, which are located on the upper and lower sides of the support plates. The bottom of the screws is fixed with U-shaped clamps. Two strip-shaped reinforcing plates are fixedly installed on the upper surface of the pressure plate, and a U-shaped clamping block is fixed to the outside of the strip-shaped reinforcing plates. Loosen the nuts to adjust the setting height of the pressure plate according to the required road surface height, and tighten the nuts after setting. The operation is convenient.

[0010] Compared with the prior art, the beneficial effects of this utility model are: A tracked power vehicle provides power to the paving mechanism. Paving materials such as concrete and asphalt are fed into the hopper and fall to the ground. A hydraulic motor drives two screw conveyors to rotate in both directions via a forward and reverse transmission mechanism. Under the action of the two screw conveyors, the paving material is spread out in the width of the road surface. A row of vibrating rods then vibrates the paving material to remove air and slurry. Finally, a pressure plate levels and compacts the paving material. This invention features a high degree of automation and produces higher quality road surfaces. Attached Figure Description
