PURPOSE:To make improvement in reliability on what trouble or the like happen, by making up a transfer device for a push plate, which extrudes these scraps loaded inside a case up to a cutting part while pushing them from rearward, into a self-propelled system consisting of the push plate and a driving mechanism actuating the former as one body. CONSTITUTION:Each base plate 3 is installed in over plural stages at a required level position at the back side of a push plate 12 which reciprocates and slides inside a projection case 11 of a scrap cutter, while a motor sprocket 14, two planetary sprockets and a pair of fire driving sprockets 16 are set up each to this base plate 13, and a chain 17 is rolled round so as to surround these sprockets 14-16. And, a wheel 23 inclusive of a pneumatic tire 24 is attached to the lower end of a wheel shaft 20 being pendently installed in the sprocket 16. This shaft 20 is supported rotatably by means of each bearing 21 set up on each base plate 3, and each of these bearing 21 is forcibly pressed toward a side wall surface 18 by a feed screw 22 whereby pressure-contact force of the tire 24 is made so as to be variable. |
