DEVICE FOR UNIFORM BROADBAND PLANTING SEEDS OF VEGETABLE CROPS Russian patent published in 2013 - IPC A01C7/00 

FIELD: agriculture.

SUBSTANCE: device for uniform broadband sowing seeds of vegetable crops comprises a scraper bar, a sowing unit of papilionaceous type, a tubular stand-drill tube, an active diffuser in the form of a plate, and a drive mechanism to oscillating motion of the diffuser. The wedged scraper bar consists of flat blades interconnected at an angle smaller than the friction angle of the plant residues, and equipped with soil-deflectors. The soil-deflectors are made in the form of rectangular plates connected to the rear edge of blades at right angles. At that the device is equipped with a covering machine. The diffusing plate oscillating horizontally is made in the form of a perforated sector and is located in the free zone between the scraper bar and the covering machine. The covering machine is made in the form of two triangular plates mounted at an angle against the motion, which is less than the angle of friction of the soil against the plates.

EFFECT: method enables to increase the width of planting the seeds and to improve the uniformity of their distribution.
