FIELD: agriculture.
SUBSTANCE: invention relates to the field of agricultural machinery industry, in particular to tools for sowing. The opener for uniform broadband sowing seeds comprises an active spreader, double-wing wedge scraper bar, covering devices, a compacting roller. The spreader is made in the form of a double-slope perforated plate and is placed over the soil surface under the drill tube. The spreader is driven to oscillating motion from the compacting roller shaft through the chain drive by a crank mechanism. The covering devices are made in the form of two ploughs with a screw mouldboard and mounted at an adjustable angle counter-motion and in front of the compacting roller.
EFFECT: constructive solution is aimed at excluding jamming the diffusing sheet, increase in the uniformity of sowing.
