<p>A self-propelled stone crusher constructed so that it can be operated even on the soft ground without lowering of the travelling performance thereof, can remove by itself such a large stone that cannot be crushed therewith, and crush stones as it excavates the superficial earth. This crusher is provided with a blade (17) fixed to the front portion of a crusher body (10), which has a crawler type driving unit (15), in such a manner that the blade (17) can be vertically moved, and a stone crushing unit (20) fixed to the rear end portion of the crusher body (10) with respect to the travelling direction of the stone crusher so that the stone crushing unit (20) can be detached and vertically moved. This unit (20) has a rotary drum (27) which is supported rotatably on both side plates (21a, 21a) of a cover member (21) opened toward the ground surface and which is provided with a plurality of bits (29) on the outer circumferential surface thereof; a repulsive plate unit (40), a granulating plate unit (41) and a sorter (42) which are arranged in a mutually spaced manner in the mentioned order in the rotational direction of the rotary drum (27) and fixed to the inner surface of the cover member (21) so that these units can crush stones in cooperation with the rotary drum (27).</p> |
