WEIGHER OF LOOSE MATERIALS Russian patent published in 2001 - IPC

FIELD: metering of loose materials, predominantly, agricultural products. SUBSTANCE: weigher of loose materials includes hopper, chute with curvilinear working surface executing oscillatory motion and mounted by hinges on hopper axis under unloading hole. Vertical partition fitted with mechanism for its forced vibration is hinged in center part of working surface of chute. Mechanism for forced vibration of vertical partition is composed of flexible tie- rod kinematically coupled to partition, one of its ends being anchored in hopper with displacement in plane of travel of chute by value equal to amplitude of its vibration relative to its another end. EFFECT: improved operational and technological capabilities. 1 cl, 4 dwg
