FIELD: agricultural engineering. SUBSTANCE: digger has frame, share with fork-shaped rods arranged in horizontal plane for defining segment, crank mechanism for imparting vibrating motions in vertical plane, and vibrating motion drive mechanism for imparting motions in horizontal plane perpendicular to progressive motion of digger. Segment chord is deviated from connecting rod direction by angle below 90 deg. Connecting rod is equipped with rotary carriage connected to frame. Crank mechanism is made in the form of three-dimensional cam mechanism with profiled slot on cylindrical surface of eccentric drum for accommodation of roller ejector therein and is provided with eccentric crank having boss. Crank of three-dimensional cylindrical cam mechanism is made cylindrical. Eccentric drum is arranged in cylindrical crank. Receptacle formed in cylindrical crank boss is adapted for receiving of roller ejector. Boss is equipped with detachable joint coupled to connecting rod.
