Theoretical study of operation of horizontally rotating cutter, determining of drive power

Abstract

The study of cultivation and repartition of soil with knives mounted at the edge of bars showed that cultivation depth is adjusted within 0.15-0.30 m by setting sealing and supporting rollers for required height relatively the cutters or with replacement of knives. The surface of sealing roller may be designed smooth or corrugated so enabling to create special lengthwise furrows at soil consolidation providing for the improvement of uniform distribution of seeds and fertilizers at succeeding working operations. Loosened strips have trapeziform section with small lower base. Unprocessed strips between the loosened strips keep soil from sliding to the channel bed. Trapeziform sections of unprocessed balks increase their strength.
