Annulated -[shporovyy] the roller of seeder- cultivator relates down agricultural machine building, namely, to the rolling up rollers of seeders, and it can be used before the sowing machines for the sub-surface packing of soil after the sowing of cereal crops. During the motion of seeder- cultivator along the field, the sown material is distributed along the bottom of fissure, which is revealed by ploughshare, and it is filled up by the soil, which descends based on the upper surface of cultivator paw. The disks annulated -[shporovogo] of roller, placed strictly on the track of that going in front of the ploughshare, being rolled, by spur enter into soil, partially [uplotnyaya] its upper layer. In this case the spur takes root before the soil by convex- curvilinear surface [R]. [Kontaktnaya] the surface of the condensed soil it increases due to the angle of the friction of soil before the soil, forming thus an increase in the density of soil directly above the seed, what ensures the complete contact of seeds with the soil as from below - seed lies beyond the dense bed, so also on top - dense layer of soil directly above the seed. The simultaneously cutting edge L [podrezaet] the rhizome of weeds. On leaving spur from the soil, rear wall Q seizes the [podrezannye] rhizomes of weeds and after-harvest remainders and will carry them down the surface of soil. As a result of the installation of spurs on the periphery of rim at the angle smaller than the angle of the friction of metal according to the soil, the earth with the after-harvest remainders, raised by spur on leaving from the soil, crumbles in its base. In this case sealing disk and throwing of soil down the chain of the sowing apparatus is excluded, ensuring thus qualitative sowing. The use of the roller of seeder- cultivator proposed annulated -[shporovogo] will make it possible to reduce tractive resistance down 15-25%, to increase the quality of sowing per 30%. |
