FEEDING-DOSING APPARATUS Russian patent published in 2005 - IPC

FIELD: agricultural engineering.

SUBSTANCE: feeding-dosing apparatus has hopper incorporating horizontal pin-type conveyor and vertical pin-type conveyor for combing out of fed mass, mechanism for automatic adjustment of velocity of horizontal conveyor, and drives for conveyors. Mechanism for automatic adjustment of velocity of horizontal conveyor is formed as beater with retractable fingers, said beater being mounted on shaft of double-armed lever with pivot joints, one of pivot joints being coupled to rheostat. Shaft is connected through sprockets and chain with drive shaft of horizontal pin-type conveyor. Drive shaft is connected through V-belt variable-speed drive consisting of drive sheave, driven sheave and V-belt with motor-reducer. Variable-speed drive is controlled by means of solenoid connected to movable disk of drive sheave of V-belt variable-speed drive. Box provided between runs of horizontal conveyor is adapted for introducing of compressed air into hopper cavity in order to provide for preliminary mellowing and cooling of mass of material.

EFFECT: increased efficiency and enhanced reliability in dosed feeding of stalk mass.
