Abstract:
A self-propelling crushing machine comprising:a machine body (2) provided with a traveling body (1); a hopper (4), a feeder (5), a selective feeder (6) and a crusher (3) which are mounted to the machine body; a conveyer (7) disposed below the machine body; and a controlling device for independently controlling said feeder, said selective feeder, said crusher and said conveyer, said feeder having a flat plate (28) and being vibrated in an obliquely upper direction with respect to a horizontal plane by a first vibration exciter and adapted to convey a material to be crushed from the hopper to the selective feeder, said selective feeder having a grizzly bar (32) and being vibrated in an obliquely upper direction with respect to a horizontal plane by a second vibration exciter, and adapted to select the material to be crushed conveyed by the feeder so as to fall down at least soil, and shingle and convey large rock to the crusher, and said conveyor discharging the at least selected soil, and shingle and material pieces crushed by the crusher, and wherein the vibrating direction of said first vibration exciter (29) is made near the horizontal plane more than the vibrating direction of said second vibration exciter (33), said second vibration exciter (33) vibrates in a magnitude more than that of said first vibration exciter (29) thereby to make large a selecting ability of said selective feeder and to make a conveying ability of said feeder substantially equal to that of said selective feeder.
