AI Technical Summary
In existing bridge and road construction, the cutting device with a single cutting plate structure is cumbersome to operate, requiring repeated movement and calibration, resulting in low construction efficiency and affecting the progress of subsequent procedures.
It adopts a combination structure of two-way lead screw, threaded block, mounting plate, rotating shaft, spline shaft, spline tube, driving wheel, driven wheel and transmission belt to realize synchronous cutting of two sets of cutting blades. It is equipped with water tank, water pump, spray pipe and spray head for dust reduction and cooling. Combined with battery and control panel, it realizes independent power and unified control of equipment.
It significantly shortens the cutting time, improves the cutting quality and accuracy, reduces dust pollution and mechanical injury risks, and enhances construction efficiency and safety.
