Joint cutting mechanism for road construction and joint cutting machine

Abstract

The invention relates to the related technical field of road construction equipment, in particular to a joint cutting mechanism for road construction and a joint cutting machine. The upper ends of thetwo side plates are connected through a top plate; a rotating shaft driven by a driving assembly to rotate is arranged at the position below the top plate; wherein the rotating shaft is sleeved withtwo sleeves which can only horizontally slide along the rotating shaft and are used for fixing the cutting knife, the two sleeves are symmetrically arranged relative to the central axis of the rotating shaft, rotating rings hinged to the adjusting assembly are rotationally installed on the sleeves, and when the adjusting assembly is triggered, the two sleeves move oppositely or oppositely. The device is novel in design, the rotating sleeve rotates to drive the threaded rod to rotate, the threaded rod moves in the vertical direction under the action of the threaded sleeve when rotating, the threaded rod drives the rotating ring and the sleeve to move under the action of the mounting plate and the connecting rod when moving up and down, and therefore distance adjustment between the two cutters is achieved, and different joint cutting requirements are met.

Description

technical field [0001] The invention relates to the related technical field of road construction equipment, in particular to a slitting mechanism and a slitting machine for road construction. Background technique [0002] From the meaning of the word, the road is the infrastructure for various trackless vehicles and pedestrians; according to its use characteristics, it can be divided into highways, urban roads, country roads, factory and mine roads, forestry roads, examination roads, competition roads, automobile test roads, workshop passages As well as school roads, etc., there were also post roads in ancient China. In addition, it also refers to the way to achieve a certain goal, the way things develop and change. [0003] In the process of road construction, it is often necessary to pave and repair the damaged road position. In order to improve the repair effect, it is necessary to cut the damaged position and then fill it. In order to ensure that the treatment position ...

Problems solved by technology

[0003] In the process of road construction, it is often necessary to pave and repair the damaged road position. In order to improve the repair effect, it is necessary to cut the damaged position and then fill it. In order to ensure that the treatment position does not affect other positions, generally the damaged part Cutting on both sides and then crushing, the cutting mechanism on the existing cutting machine generally uses a single cutting knife for cutting, the cutting efficiency is low, resulting in low construction efficiency
