Problems solved by technology

However, the construction outside the tunnel and bridge culvert is short due to the short screw conveying mechanism, resulting in a lack of materials at both ends, which affects the smoothness and compactness of the road surface. The road section outside the tunnel is the main road section of the entire road section, so the construction quality of the entire road section is affected. Serious impact

Embodiment Construction

[0037] Such as figure 1 and figure 2 The shown folding screw feeding mechanism for a paver includes a first screw shaft 3 arranged on one side of the paver 1 and a first material baffle plate 4 located on the front side of the first screw shaft 3, and a set The second screw shaft 9 at the end of the first screw shaft 3 away from the paver 1 and the second material baffle plate 10 located at the front side of the second screw shaft 9; the first material baffle plate 4 is provided with a first support frame 7. The end of the first screw shaft 3 away from the paver 1 passes through the first support frame 7 and rotates with the first support frame 7. One end of the first screw shaft 3 and the second screw shaft 9 One end is a detachable connection, and the end of the first material retaining plate 4 away from the paver 1 is hinged with a second material retainer for driving the second screw shaft 9 to rotate after the second screw shaft 9 is detached from the first screw shaft ...

Abstract

The invention discloses a foldable spiral delivery mechanism for a paver. The foldable spiral delivery mechanism comprises a first spiral shaft, a first retaining plate, a second spiral shaft and a second retaining plate. A first support frame is arranged on the first retaining plate; one end, away from the paver, of the first spiral shaft penetrates the first support frame and is in running fit with the same; one end of the first spiral shaft is detachably connected with one end of the second spiral shaft; one end, away from the paver, of the first retaining plate is hinged to the second retaining plate; a second support frame is arranged on the second retaining plate; one end, away from the paver, of the second spiral shaft penetrates the second support frame and is in running fit with the same; a power device is mounted on the paver. By detachable connection of the first spiral shaft and the second spiral shaft and a foldable mode of the second spiral shaft, the foldable spiral delivery mechanism can ensure paved materials to be sufficient when a road surface is widened or narrowed, further flatness and compactness of the road surface are guaranteed, and paving quality of the road surface is improved.

Description

technical field [0001] The invention relates to a material conveying mechanism, in particular to a folding screw conveying mechanism for a paver. Background technique [0002] Paver (road paving equipment) often enters and exits tunnels, bridges and culverts during road construction in mountainous areas, and the width of the road surface inside and outside the tunnels, bridges and culverts is different. Construction on such a road section is usually equipped with screeds that can be hydraulically extended at both ends to meet the needs of changes in paving width. However, the screw conveying mechanism in front of the screed can only be changed mechanically because it needs to continuously and evenly convey materials. Width, the usual construction is set according to the width of entering the tunnel, the quality of the construction paving in the tunnel and bridge culvert is guaranteed. However, the construction outside the tunnel and bridge culvert is short due to the short ...
