Abstract

The invention provides a road construction device capable of conducting dust fall. The road construction device is used for conducting grinding on the local protrusion on the construction road surface in the road construction process. The road construction device comprises an external shell (8), a motor (9) and a grinding head drive rod component (6) driven by the motor (9). The motor (9) is in power connection with a splined hole in a drive sleeve portion (61) of the grinding head drive rod component (6) in the axial direction in a slidable mode through a spline rod (91) fixedly connected with the motor (9). The drive sleeve portion (61) of the grinding head drive rod component (6) is fixedly connected with a grinding head mounting rod portion (62) of the grinding head drive rod component (6) through gradually contractile connection portions (612).

Description

technical field [0001] The present application relates to the field of construction machinery, in particular to a road construction device for reducing dust. Background technique [0002] In some construction sites, such as road construction, etc., local leveling of the subgrade surface is often required, for example, some local protrusions caused by construction defects need to be polished. [0003] The flatness result of this grinding has a great influence on the quality of subsequent pavement surface construction, for example, occasions with high requirements for the levelness of the road surface, such as expressways, have particularly high requirements for such levelness. At the same time, because the amount of material removed in this local grinding is often not very large, traditional grinding machines are often not suitable due to factors such as equipment costs. Contents of the invention [0004] The object of the present invention is to provide a road constructio...
