FIELD: making trenches in bottom and surface soil and taking soil for subsequent processing. SUBSTANCE: working member of device is made in form of two inclined chutes with cutting lower end; working members are suspended by means of hinges under horizontal load- bearing beam with opposite position of their cutting ends ensuring alternate gripping of soil at reciprocating motion of device. Device is towed along assumed trench by rope secured to one of chutes. Chute slides freely over surface of soil resting against it and guiding the device over trench; other chute cuts and grips soil by its lower end. Under action of towing force, soil gripped by chute is moved upward and is thrown beyond edge of trench to soil carrying truck. During motion of device to opposite side, functions of chutes are reversed. EFFECT: extended capabilities. 1 dwg
