Abstract
PURPOSE: To effectively perform the excavation of a ditch with a sufficient raking-up capability whatever type of soil is excavated by a method in which paired screw cutters are lapped on each other in such a way that they may not interfere with each other and split raking plates by which soil and sand adhered to the blade of the screw cutter are removed are provided to the blade of the screw cutters.
CONSTITUTION: A base 3 freely rocking by an oil-ressure cylinder 5 is pivotally attached to the tip of a self-running vehicle 1, and bar-like screw cutters 6 and 6' rotating in mutually opposite directions with the same revolving number are supported on the base 3. In the excavation of a ditch, the base 3 is inclined downwards, the screw cutters 6 and 6' are turned to excavate the ground by cutting blades 12, and excavated soil is raked up on the back side by spiral blades 10 and discharged by an earth-moving screw 22. At this time, the split raking plates 18 and 18' are cut into the spiral blades 10 to prevent the adherence of soil and sand to the blades 10. The screw cutters 6 and 6' are so lapped on each other that they can pass freely without causing any partial interference with each other in the same space.
