High-strength drainage ditch cover plate machining device and machining method thereof

The invention relates to the field of ditch cover plate machining, in particular to a high-strength drainage ditch cover plate machining device which comprises a main conveyor support and an auxiliary conveyor support. The high-strength drainage ditch cover plate machining device is composed of a positioning mechanism and a cleaning mechanism. When the ditch cover plate is conveyed to the position of a limiting plate and then stops moving, a motor is started to enable a supporting sleeve to drive a cutting machine body to horizontally move on a screw rod to cut the ditch cover plate, after cutting is finished, a T-shaped toothed plate is meshed with a corresponding transmission toothed ring, the transmission toothed ring drives a rotating rod to rotate, and a circular toothed ring on the rotating rod is in meshed transmission with a rack; then a sliding rod pulls a rotating wheel to move, so that the rotating wheel is matched with an inclined groove to drive an adjusting plate and a limiting ...
