FIELD: continuous weighing and proportioning of loose materials transported by belt conveyers. ^ SUBSTANCE: proposed weigher has two roller supports mounted by means of bridge and frames and, counter weight, rate and weight sensors. Roller supports are interconnected by summing-up unit made in form of two levers of different length which are located along longitudinal axis of belt forming angle of inclination of 5 deg.; they are connected to scaling-up lever by means of connecting member. One end of scaling-up lever is provided with counter-weight and other end is used for transfer of force to weight sensor. Connecting member is provided with two articulated joints. ^ EFFECT: enhanced accuracy and reliability during extended period of time. ^ 3 cl, 5 dwg |
