Abstract

PURPOSE: To prevent rupture of material such as coal in transporting the same through a spiral chute, by feeding the coal in the form of layer to a discharging means by stopping operation of the discharging means located just downwards of the spiral chute.
CONSTITUTION: A photoelectric sensor 20 is provided on the front side of conveyor 12 which is carried on the body of ship loader 1. When it is detected by the sensor 20 that coal A is passed on conveyor 12, a timer is actuated to drive a trimmer (10) driving motor after passing of a predetermined time period. Set time for the timer is determined such that amount of coal carried by conveyor 12 is sufficient to keep layer of coal along the passage from the inlet of spiral chute 7 to the outlet of chute 9. With such an arrangement, coal A can be fed steadily and continuously to keep coal layer always in hopper 8, and the coal layer serves as cushion for coal A dropped from spiral chute 7, so that rupture of coal can be prevented effectively.
