TILLAGE TOOL FOR EROSION-PREVENTIVE SOIL TILLAGE

FIELD: agricultural engineering. ^ SUBSTANCE: tillage tool has frame consisting of front, rear, right-hand and left-hand bars with supporting-regulating device and working tools for basic soil tillage, said tools being made in the form of ripping-undercutting hoes. Central hoe has furrower and is fixed on front bar along tool longitudinal axis. Right-hand and left-hand ripping-undercutting hoes are mounted on respective lateral right-hand and left-hand bars of frame, symmetrically with respect to one another and at an angle to longitudinal axis of tool whose apex is oriented toward its rear part. Mounted on frame are right-hand and left-hand carrier members with right-hand and left-hand disk tools pivotally fixed on carriers, said tools being arranged at both sides of tillage tool, at an angle to its longitudinal axis. Right-hand and left-hand carrier members of disk working tools are positioned so as to be adjusted in vertical plane relative to frame. Disk-type working tool is pivotally secured in rear part of tillage tool, on one of side bars, in front of any outer ripping-undercutting hoe, and adapted for forming of stubble coulisse. Disk-type working tool is adapted for moving along side bar of frame and in vertical plane. ^ EFFECT: increased erosion-preventive effectiveness and reduced consumption of power during operation of tillage tool. ^ 3 dwg
