PURPOSE:To supply grain of proper blending ratio without causing blending unevenness even when conveying velocity is changed by connecting a grain detecting sensor provided to a discharge hopper or a carrier means with a discharge means via an arithmetic controlling device. CONSTITUTION:When conveying velocity is changed during blending operation by slip of a belt conveyor 13, rice particles discharged from a weighing discharger 6 can not reach the lower part of the weighing discharger 7 in a prescribed time. At this time, a sensor is turned off because a detection lever 51 is not rotated and even when a prescribed time elapses, the sliding shutter 42 of the discharger 7 is not opened and thereby rice particles are not discharged. When the lever 51 is turned by rice particles, the sensor is turned on and the shutter 42 of the discharger 7 is opened to discharge rice particles. Therefore even when conveying velocity is changed by slip of the conveyor 13, rice particles of proper blending ratio can be supplied without causing blending unevenness. |
