BULK FEED DISPENSING LINE Russian patent published in 2002 - IPC

FIELD: animal farming. SUBSTANCE: line has feeding hopper communicated to spiral-type conveyor equipped with cylindrical housing, and group dozers positioned under discharge windows made in housing. Dozers have rotary gates connected to drive mechanism and to feed dose regulator. Drive mechanism for gates of each dozer is formed as vacuumizer containing pair of membrane-type chambers, vacuum pipeline and vacuum pump with vacuum regulator. Feed dose regulator is formed as stem pivotally connecting each vacuum chamber with dozer gate, which is positioned in conjunction with hopper front wall for adjustable displacement through the height of dozer. Each dozer has vertical guides adapted for receiving front walls and equipped with retainer. Conveyor housing is provided with valve for emergency discharge of feed and with vacuumizer pivotally connected to conveyor housing through stem and communicated with vacuum pipeline. Feeding hopper is equipped with spherical feed caving device mounted in its lower part for contacting with conveyor spiral. Such construction allows feed doses to be dispensed into feeders with increased precision. EFFECT: simplified construction and maintenance of drive mechanism and gates and improved regulation of feed doses. 4 cl, 6 dwg
