AI Technical Summary

Technical Problem

In existing technologies, the chisel generates a large amount of dust when breaking roads, and the top plate moves up and down synchronously with the chisel, resulting in significant dust generation inside the protective cover, which affects the operator's judgment of the location of the hammer impact on the road surface and the breaking condition.

Method used

A road construction trench excavation device was designed, which adopts an intercepting top plate and an intercepting side cover. The intercepting top plate is equipped with intercepting mesh and intercepting straight seams. Combined with atomizing nozzles and a water pump system, it is used for dust suppression and cooling. The inside of the intercepting straight seams is cleaned by a scraper and brush to ensure the visibility of the construction.

Benefits of technology

It effectively reduces dust, improves visibility and safety at the construction site, reduces noise, ensures cooling of the drill rod, and prevents equipment damage.

Abstract

The utility model discloses a road construction trench excavation equipment relates to road construction technical field, including the drill rod main part, and the drill rod main part is equipped with the intercepting roof, and the intercepting roof is fixedly installed on the drill rod main part through the fixed mechanism, and the intercepting roof is evenly distributed with a plurality of intercepting mesh holes, and the outside of intercepting roof is equipped with the intercepting side cover, and the outside of intercepting side cover is evenly provided with a plurality of intercepting straight seams along the circumferential direction, and the top of intercepting roof is fixedly installed with the symmetrical guide rod, and the intercepting side cover is slidingly connected on the outer surface of guide rod, and the top of guide rod is fixedly connected with the anti -drop cap, the utility model discloses through the setting of intercepting mesh hole, intercepting straight seam, and air can be relatively smooth through, make air flow relatively more dispersed and orderly, this reduces the strong air vortex and air flow impact that produces because of intercepting roof quick lift, and the disturbance of air in intercepting roof, intercepting side cover is relatively small, avoids producing the relatively large dust influence operator observation construction condition.
