EROSION-PREVENTIVE TILLAGE TOOL Russian patent published in 2008 - IPC A01B13/16 A01B49/02 

FIELD: agricultural engineering, in particular, erosion-preventive tillage equipment.

SUBSTANCE: erosion-preventive tillage tool has frame with rolling supporting mechanism. Tillage devices are fixed on frame so as to cut furrows and place stubble brushes therein. Batteries mounted on frame are formed as bearing members with disk-type working devices pivotally fixed and designed for undercutting of soil top layer in conjunction with stubble and forming brushes. Disk-type working devices are arranged at both sides of longitudinal axis of tillage tool, at an angle thereto. Tillage devices are formed as mellowing-undercutting hoes for shallow soil tillage. Furrows are formed by means of furrow cutting devices mounted on tines of outer tilling, mellowing and undercutting hoes. Furrow cutting devices are independently adjusted with regard to furrow depth within soil tillage depth provided by mellowing and undercutting hoes. Bearing members are arranged at both sides of longitudinal axis of tillage tool, at an angle thereto so that its apex is directed toward front part of tillage tool. Bearing members are mounted on tillage tool frame so that angle of attack of disk-type working devices may be adjusted. Brushes whose bases are placed into two longitudinal furrows are finally formed by adjacent passes of tillage tool.

EFFECT: increased erosion-preventive resistance of plow land and reduced consumption of power.
