VIBRATORY HOSE-TYPE SEEDING UNIT OF DRILL Russian patent published in 1998 - IPC

FIELD: agricultural engineering. SUBSTANCE: seeding unit has two hoppers, two dosers, each connected to related hopper from below, and tubular hoses connected to dosers with their inner end through flexible connectors. Hoppers together with dosers and hoses are mounted on drill frame. Outer ends of hoses are connected to frame through adjustable hangers. Eccentric boom drive mechanism is attached to mid portion of drill. Pipe of each boom is composed of two equal halves. Plate mounted at pipe halves detachment location is adapted for dividing working cavity of boom into upper material transportation zone and lower seeding zone. Plate is provided with lengthwise windows. Material seeding zone is divided along the whole length by vertical transverse walls into separate independent sections. Such construction allows maximum uniformity of material distribution to be provided independent of field relief. EFFECT: increased efficiency by uniform distribution of seeds and prolonged service life. 4 dwg
