SCARIFIER WITH ADJUSTABLE POSITION OF WORKING MEMBERS

摘要

The invention relates to agricultural machinery, in particular, to means of adjusting working members for deep and surface soil tillage. The technical inventive result is aimed at simplification of general design, improvement of operation reliability and operation quality in soil tillage, characterized in that a scarifier comprises a groove 7 with an oval hole made on a post 1, an adjusting mechanism comprises a washer 8 in the form of different sized polygon with fixed turn angles, the washer is put in the groove 7 capable for fixing in different positions, wherein the fixed turn angles are marked by digits, one of digits stamped on the polygon corresponds to a mark made on post of the working member, wherein each digit corresponds to a definite angle of the post inclination from its vertical position. Such design of the adjustment of the working member movement in soil tillage makes the adjustment of angle simpler, reduces labor and metal consumption, improves operation reliability and its quality.
