ABSTRACT:
A downward-flow trough angle adjusting device for a color discriminating machine having a downward-flow trough mounting device for detachably mounting the trough, the device being secured to the upper surface of a frame defining a photoelectric discriminating chamber to provide a unitary structure. The photoelectric discriminating chamber frame is connected at one side to a machine frame for pivotal movement while being movably supported at the other side by the machine frame through a threaded shaft-nut assembly. Thus, as the photoelectric chamber frame is vertically moved at the other end by actuating the threaded shaft-nut assembly to adjust the angle of inclination of the downward-flow trough, the photoelectric discriminating chamber frame also moves together with the downward-flow trough, thereby enabling the downward-flow trough to be correctly positioned at all times with respect to a collecting tube in the photoelectric discriminating chamber for receiving the granular material of interest from which granular materials of colors distinct from that of the granular material of interest have been separated by electrophotographic color discrimination.
