WEIGHT MEASURING DEVICE FOR BULK MATERIALS Russian patent published in 2012 - IPC G01G13/04 B65B1/32 

FIELD: mechanics.

SUBSTANCE: invention includes frame with bunker installed on it; bunker has a gate at the outlet; neck with sealing mechanism is installed under bunker; the above mechanism is equipped with bag hold-down clamps; neck is connected to weight measuring mechanism made in the form of balance arm that has counter-balance on the other end. There is also accurate weight adjustment device, gate position adjustment device and dosing cutoff device. Gate for high and low dosing flows is common. Weight accurate adjustment device is made in the form of adjusted spring hinged to one end of the balance arm, and two adjusted stops for restriction of amplitude of oscillation of this end on the neck end; at that, the second end of balance arm is equipped with adjustable pusher for interaction with the dosing cutoff device. Dosing cutoff device is fixed on the frame and made in the form of contact platform with possibility of adjusting by means of a screw and a roller, which are connected to each other by means of articulation system. At that, platform and roller are equipped with their own counterbalances, and roller has the possibility of interaction with the gate position adjustment device. Gate position adjustment device is made in the form of rod with cam, which is adjusted as to length and kinematically connected to the gate, for interaction with roller of the dosing cutoff device. Neck has rectangular section.

EFFECT: simpler design and lower cost of the bench; increasing the efficiency and dosing accuracy.
