SHARE Russian patent published in 2001 - IPC

FIELD: agricultural engineering. SUBSTANCE: share has casing, two disks of different diameters having sharpened outer edges, roller bearings, seed pipe, baffle (sweeper), pressure spring and carrier. Disk rotation shafts are arranged in casing so that disks converge in front part to define wedge with acute angle of 11-12 deg. Contact (convergence) points are on line extending through centers of circles and defining an angle with vertical line of δ=40-46 deg for rotation at different frequencies and cutting of stubble and plant remains. Such construction provides for self-cleaning of share and, consequently, eliminates manual work for additional cleaning. EFFECT: enhanced reliability in operation, improved seeding quality and increased yield. 4 dwg
