GRAIN FLOW RATE DETECTOR IN RICE HUSKING SORTING MACHINE

摘要

PURPOSE:To stabilize the feed rate control of paddy by forming both the runway of finishing rice and the runway of returning paddy so that the velocity of finishing rice in the terminal of the runway thereof is made equal to the velocity of returning paddy in the terminal of the runway thereof. CONSTITUTION:Blending rice of paddy and unmilled rice which have been husked by the husking rolls 3 is introduced into a rotary sorting drum 4 and unmilled rice is sorted from paddy. Unmilled rice is discharged to the outside of the machine as finishing rice via a finishing rice discharging passage 7 and also paddy is returned to the husking rolls 3 as returning paddy via a returning paddy passage 12. A finishing rice runway 8 is provided to the discharging passage 7 and a returning paddy runway 13 is provided to the returning paddy passage 12 respectively. Both a finishing rice sensor 10 and a returning paddy sensor 15 made of a piezoelectric element are arranged to the terminals of the respective runways 8, 13. Both runways are formed so that the velocity of finishing rice in the terminal of the runway 8 is made equal to the velocity of returning paddy in the terminal of the runway 13. As a result, the feed rate control of paddy is stabilized.
