THEORETICAL AND EXPERIMENTAL SUBSTANTIATION OF THE DESIGN OF AN OPENER FOR INTRASOIL BROADCAST SOWING OF GRAIN CROPS

Existing seeder openers for intrasoil broadcast sowing of grain crops do not fully provide quality seeds scattering. Low nonuniformity of seeds scattering can be assured by vibro-distributers but they have a complicated design. An original opener design for quality intrasoil broadcast sowing is proposed. The V-shaped sweep of the opener consists of cutting blades which create a closed subsoil space.
A pendulum scatterer in the form of a hemisphere is pivotally suspended inside. Theoretical studies are based on classical mechanics. As a result of theoretical investigation, an expression is obtained for determination of the length of a grain fallen in the under-sweep space. The optimal parameters of the scatterer are determined experimentally: it s base diameter, its height and its location according to the bottom of the furrow.
