When the cutting wheel needs larger driving force along the track, a counterweight needs to be used as a bin pressing object on the ditching device, so that the center of gravity of the power platform carrying the ditching device is easily positioned outside the walking range, and the balance is easily lost when the power platform moves; there is also a trenching apparatus mounted on a power platform such as an excavator or bulldozer, for example US 4542940. The frame is a rectangular frame under the cutter, the four corners of the frame are installed and run, the distance between the cutter and the running is controlled through the extension of the cutting arm, the cutting range can be enlarged under the condition of no movement of the running, when the cutter extends out to a far position, if the weight of the cutter is large, the stability is easy to deteriorate, so that the weight of the cutter and the extension stroke are easily limited, and the ditching operation on harder rock strata is very unfavorable.
