PCT No. PCT/JP95/01538 Sec. 371 Date Jan. 14, 1997 Sec. 102(e) Date Jan. 14, 1997 PCT Filed Aug. 2, 1995 PCT Pub. No. WO96/04075 PCT Pub. Date Feb. 15, 1996A method of driving a dual axis shearing type crushing machine mounted on a self-traveling vehicle body for crushing crushable building scraps at a building wrecking site. The crushing machine includes a pair of rotary shafts provided with a plurality of cutters within a housing on the vehicle body. The rotary shafts are supported sidelong so as to be concurrently rotatable, and the crushing machine also includes a scraper attached to an inner surface of the housing on the vehicle body so as to oppose the cutters and the rotary shafts. The method includes the steps of: (a) rotating the pair of rotary shafts in a forward direction for a first predetermined time duration so that the cutters crush the crushable building scraps into crushed pieces; (b) thereafter rotating the pair of rotary shafts in a reverse direction for a second predetermined time duration so that the crushed pieces are drawn into and trapped in a spacing provided between the scraper and the cutters and the rotary shafts at an outlet side of the crushing machine within the housing; and (c) continuously repeating the steps (a) and (b) in succession so as to consecutively crush the crushable building scraps into the crushed pieces and force the crushed pieces to be fed from the outlet side of the crushing machine out of the housing so as to enable the crushed pieces to be discharged onto a conveyor provided on the vehicle body without clogging of the crushed pieces in the spacing.
