PLOW-CULTIVATOR AND WORKING TOOL FOR PLOW-CULTIVATOR

摘要

FIELD: agricultural engineering. SUBSTANCE: plow-cultivator has plow bodies arranged in spaced relation with respect to one another. Each plow body has plow share and combined moldboard having wedge-shaped immovable member and concave disk with deflecting-mellowing members on its surface. Angle α between plane extending through ends of each concave disk and longitudinal axis of symmetry of plow-cultivator is selected within the range of 1-87 deg. Disk end is bent to side opposite to disk concavity for angle B of 1-187 deg. Disk is equipped with openings for replaceable inserting of deflecting-mellowing members. EFFECT: increased efficiency in soil plowing performed simultaneously with cultivation and improved soil grinding. 3 cl, 4 dwg
