Color (色) photoelectric sorting machine sorting device

摘要

The machine has a frame on the upper portion of which is a grain-supplying device with an inclined chute(3) to control the flow of grain between two photoelectric chambers (9,10). Light sources(5,6,7,8,) are arranged in the two chambers. The photoelectric chambers are protected from the grain-sorting chamber(12) by dust-proof transparent windows, with each chamber containing backgrounds(15,16) and light-sensitive elements(17,18) with focusing lenses. Pressurized air is fed to a nozzle device(21,22) through a solenoid valve(23). The nozzle device is capable of scattering or changing the grain flow in response to appropriate signals originating in the photoelectric circuit.
