Abstract

A dustproof road construction device is used for polishing local projections on a constructed pavement during road construction. The dustproof road construction device includes an outer shell (8), a motor (9) and a polishing head driving rod part (6) driven thereby. The motor (9) is connected to a spline hole in a driving sleeve part (61) of the polishing head driving rod part (6) through a fixedly-connected spline rod (91) in an axial-slidably power connection manner. The driving sleeve part (61) of the polishing head driving rod part (6) is fixedly connected to a polishing head mounting rod part (62) of the polishing head driving rod part (6) through a gradually-shrunk connection part (612).

Description

technical field [0001] The present application relates to the field of construction machinery, in particular to a dust-proof road construction device. 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 dust-proof road constru...
