Title: Apparatus for detecting speed of granular substance
Inventor: TOKI HARUMITSU
IPC: G01P5/22
Filed: 1996-02-14
Abstract: PROBLEM TO BE SOLVED: To highly accurately detect a moving speed of a granular substance by judging the moving speed from a frequency obtained by analyzing a converted voltage value of the amount of light received at a photodetecting part of an optical sensor. SOLUTION: While mixed rices supplied to an oscillating/selecting plate 2 are being moved from a feed side 2a to a discharge side 2b in a longitudinal direction, the rices are oscillated in a reciprocatory manner slantwise up and down in a lateral direction. Small unpolished rices of a large specific weight are deflected to an upper side 2c, while large unhulled rices of a small specific weight are deflected to a lower side 2d. Mixed rices not selected yet are sorted at a central part, and taken out by an unpolished rice partition plate 4 and an unhulled rice partition plate 5. An unhulled rice/unpolished rice-judging sensor 6 projects near infrared light including a wavelength band absorbed by moisture from a light-emitting part to grains. Only the wavelength band absorbed by moisture is allowed to pass an optical filter part and sent to a photodetecting part.  The near infrared light is converted at an infrared-detecting element part to a voltage of a size corresponding to the amount of the wavelength band. A judging part analyzes a frequency of the detected voltage. A moving speed of the grains is thus measured highly accurately.
