Description

Technical Field

[0001] This utility model relates to the field of road construction paving technology, and more specifically, to a paving device for municipal road construction. Background Technology

[0002] Crushed stone paving equipment is a type of road construction machinery that can evenly spread crushed stone on the roadbed. It mainly consists of a hopper, support rollers, skids, V-shaped scrapers, widened side plates, and running wheels. The hopper is towed behind a dump truck, which supplies and pulls the paving operation. The front of the hopper is supported on the rollers. When the crushed stone paver is towed for short distances, the rear is supported on the skids to reduce the specific pressure on the subgrade and improve the smoothness of the paving layer.

[0003] A search revealed that Chinese utility model patent application number CN202421874335.1 discloses a crushed stone paving device for municipal road construction, including a support frame and a paving mechanism. The paving mechanism includes a material pouring frame and a scraper. A filter grid is fixedly installed on the left side of the material pouring frame, and mounting plates are fixedly installed on both the front and back sides of the left end of the material pouring frame.

[0004] When the crushed stone is laid, larger stones are intercepted by the filter screen as they slide down from the unloading rack. Workers stand inside the standing operating frame to process the intercepted stones to prevent clogging of the filter screen. After the stones fall onto the road through the filter screen, they are spread out by the "V"-shaped stone-dredging slabs, and excess stones are pushed to both sides. Although the filter screen can intercept large stones, the high frequency of manual cleaning affects construction efficiency and poses safety hazards. In addition, it is not convenient to process and reuse the stones, resulting in waste of stones. Utility Model Content
