ABSTRACT:
A conveyor carries cans or other refuse from a source of cans to a jaw crusher. The conveyor is adapted to drop cans generally one at a time into a bin, and the bin has an opening to release each can when the jaws open to receive it. In the open position, the jaws are spread far enough apart so that the can drops to the bottom thereof. A flap is provided at the bottom to hold the can between the jaws. The end of the flap extends to a position above the bottom of the stationary jaw. As the jaws come together in crushing, the moving jaw cams the flap downward along the stationary jaw. However, the flap is not cammed entirely out of the area beneath the jaw until the jaws have come together to hold the can. The flap ensures that no lip is formed on the can. After the jaws close, the flap is moved out from beneath the jaws so that when the jaws open, the crushed object can fall out of the jaws for carrying away. The machine also has a knock-off mechanism to ensure that generally only one can drops off the conveyor at a time. The knock-off system includes a rotating brush so that extra cans piled above cans lying on the conveyor are knocked off the conveyor. A ramp is placed adjacent the brush to direct the cans back to the source of cans rather than along the conveyor. Magnetic separation is accomplished in the conveyor for separating aluminum and steel cans. A kick-out mechanism is also provided for allowing movement of the stationary jaw when an incompressible object falls between the jaws. The kick-out mechanism is adjustable and includes a shock absorber to cushion the stationary jaw and prevent its return too quickly to its original position.
