FIELD: agricultural engineering, in particular deep tillage equipment. ^ SUBSTANCE: working tool has tine with blade at its front part and drainer with conical tip fixed on lower end of tine. Conical tip is formed as cut part of hollow cone. Cut part is defined by intersecting plane extending in parallel with axis of symmetry of cone and is disposed in horizontal plane at lower end of tine. Conical tip is connected with lower part of tine through pair of mounting pins inserted into process openings of conical tip and floating members, which are equipped with mating conical surface conjugated with cavity of cut part of hollow cone. Axes of process openings are oriented toward axis of symmetry of hollow cone. ^ EFFECT: reduced power consumption and increased efficiency. ^ 3 dwg |
