The working body of a quarry excavator includes at least one rotor with buckets equipped with static teeth secured on a working edge of the bucket and with impact teeth connected with impact devices which are assembled on the front wall of the bucket. The rotor is equipped with reflecting lips hinged on its rim and designed to turn by means of levers during bucket unloading; also one end of the lever is jointed to the reflecting lip, while the other is equipped with a roller traveling in guides made in form of an oval wheel rigidly fixed on a rotor shaft.
