DRILL FEED

摘要

FIELD: agricultural engineering. SUBSTANCE: vibratory feed of drill has frame on which hopper is mounted on brackets. Lower part of hopper terminates in rectangular neck. Feeding device with drill tube tips is connected to hopper from below through flexible suspensions. Feeding device drive is mounted on bracket. Inverted-V lip serves as bottom of hopper rectangular lower neck. Side walls of neck are arranged square to direction of vibrations of feeding device. Ports in smaller walls of neck are overlapped by meters adjustable in vertical, each provided with two ports. Vertical port coincides with port in smaller wall of hopper neck, and horizontal one is pointed towards bottom of feeding device housing. EFFECT: enhanced operation of drill feed owing to provision of mobility for entire upper layer of seeds in feeding device and possibility of adjusting thickness of layer. 6 dwg
