[0037] The slotting trolley 1 is equipped with a slotting mechanism and moved to the slotting position of the road. The slotting driving mechanism drives the slotting wheel 2 to rotate. The vertical driving mechanism drives the slotting wheel 2 and the front and rear reciprocating driving mechanism downward to approach the road surface.

[0040] Furthermore, if the grooving depth is large, for example, the depth is greater than or equal to half the radius of the grooving wheel 2, the depth is divided into at least two descending cutting depths. First, the first depth is cut according to the above operation, and then the grooving work of the second depth is performed downwards, and so on, until the total grooving depth is equal to the specified grooving depth.

[0041] The slotting mechanism is carried by the slotting trolley 1 and moved forward a specified distance until the slotting wheel 2 is close to the uncut part, and then the swing member 5 is driven forward by the forward and backward reciprocating drive motor 3 to continue the slotting and cutting operation; according to the above operation, the road is continuously cut until all the slotting work is completed.
