BELT-CONVEYER WEIGHER Russian patent published in 2002 - IPC

FIELD: weight measuring equipment, weighing loose material on belt conveyers. SUBSTANCE: belt-conveyer weigher includes two double-arm platform balances 1, 2 with grooved weight roller bearings 9, 10 resting against weight transmitters 7, 8, reference weight 16 and mechanism 17 of its displacement. Platforms 1 and 2 are placed on different sides of single stationary roller bearing 15 to exclude their mutual influence in calibration and testing. Outer arm of each platform is fitted with two counterweights 5, 6 for their movement along arm of platform and leans against one weight transmitter. Inner arm of each platform is equipped with prism 12, 13 for suspension of sample weights. Weight transmitters 7, 8 and prisms 12, 13 of platforms are positioned on different sides of conveyer. EFFECT: raised accuracy of belt-conveyer weigher, potential for calibration and test without stopping technological process. 2 cl, 2 dwg
