SOIL TILLAGE TOOL Russian patent published in 1998 - IPC

FIELD: agricultural engineering, in particular, equipment for deep and superdeep soil digging in irrigated agriculture, may be used for water, gas or oil pipeline laying or in dam or road construction. SUBSTANCE: soil tillage tool has frame constructed from longitudinal and transverse bars with cantilevered ends, brackets for hitching frame to power unit, carrier wheels and tillage members mounted for movement and repositioning on transverse bars and connected with bars through brackets with attachment members. Transverse bars are formed from two C-shaped bars or channel bars arranged in parallel and faced with their horizontal strips one to another. Equally spaced axially aligned distance sleeves are mounted on vertical strips in offset relation to upper horizontal strips. Distance sleeves are adapted to receive attachment members for retaining tines of soil tillage members. Brackets have pairs of supporting rollers and are formed from two parallel plates mounted at right angles to tine side surfaces along their length. Three pairs of axially aligned openings are made in upper part of plates, with two pairs of openings being adapted for attachment of tillage members on transverse bars of frame and third pair of openings - for mounting working member in transport position. Fourth pair of openings is arranged in symmetry with first pair of openings below opening for receiving working tool in its transport position and adapted for accommodation of supporting roller pins. Supporting rollers are joined with horizontal strips of transverse bars. EFFECT: wider operational capabilities and enhanced reliability in operation. 11 cl, 13 dwg
