Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, devices for the widespread sowing of seeds of agricultural crops in wet soil. The aim of the invention is to increase the uniformity of sowing of seeds in the depth of their embedment in moist soil. The device for the spread sowing of seeds contains a frame mounted on it a bunker 2 for seeds, sem wires 3, a scattering organ 4, made in the form of a disk with blades in the form of a hyperbolic sinusoid, furrow forming roller 5 and embedding device 6. When the seeding unit moves, furrow forming the roller 5 forms the grooves in the shape of a rectangular triangle, and the seeds arrive via this seven wires 3 on the blades 7 of the rotating disk 8 and are scattered over the floor surface in the furrows formed up to the stop in its vertical hour be 3 il.

Claims (1)

Claim A device for dispersed seeding of seeds, comprising a frame and a furrow-forming roller 20 with rollers in series, a hopper with a spreading sowing apparatus, and a seeding apparatus, characterized in that, in order to increase the uniformity of seeding along the depth of their placement in moist soil, each protrusion of the furrow-forming roller has a vertical and inclined face, the latter being inclined to the vertical at an angle greater than the angle of repose of the seeds, 30 and a scattering metering device It executes a horizontal disc with curved blades, of which each curve has the form of a hyperbolic sine wave. view In fig.Z Compiled by T.
