FIELD: earth-moving machines.

SUBSTANCE: working element is made in the form of two separately controlled V-shaped rotors with possibility of changing the angle of their inclination in the vertical plane to the opposite one. Rotors rotation drives are made reversible, which allows their use as running wheels during transportation within the working zone. Working movement mechanism is made in the form of two hydraulic stops operating in antiphase in automatic mode, which are buried in turn in the ground at the trench bottom. Engine-power plant is located between working element and mechanism of working movement, contains diesel engine and hydraulic pumps remotely controlled by operator. Body is made in the form of a backbone girder of a box section, the compartments of which are containers for fuel, oil, hydraulic working fluid and remote control equipment. Rotary working member is equipped with ski supports which are adjustable in height, limiting the depth of the rotors.

EFFECT: reduced dimensions, simplified design of machine and increased level of operator’s safety.
