CONTINUOUS SOIL TILLAGE CULTIVATOR Russian patent published in 2017 - IPC A01B73/04 A01B35/00 A01B49/02 

FIELD: machine building.

SUBSTANCE: invention relates to agricultural machine building, in particular, to continuous surface soil tillage tools. Cultivator for continuous soil tillage comprises sectional frame with two symmetrical wings, trailed hitch tongue, rigidly fixed in frame central part, support-transport wheels in form of wheel pair, coupled with hydraulic cylinder and hinged on frame, working elements and planer. Length of cultivator trailed hitch tongue provides cultivator coverage working width to longitudinal distance between trailed shackle and working members center row ratio of more than 1.5. Wings working width is equal to half of central section width. On central section and frame wings working members two spring suspensions are fixed. Adjacent working elements in sequential in travel direction rows are arranged with overlapping. Hinges axes of central section connection with frame wings are arranged above of working members suspensions upper points, and at front hinges central section and frame wing are additionally connected by means of articulated lever and tie-rod. Lever comprises three hinges: lower is connecting lever with frame central section, upper is with tie-rod, central is with hydraulic cylinder rod, which is also pivotally connected with cultivator frame central section. Tie-rod has two hinges, one of which is connected to frame wing, and second is with lever. With retracted hydraulic cylinder rod upper lever hinge is located in one horizontal plane with central section and frame wing pivot joint. At that, ratio of distance between lower and central hinges of lever to distance between lever external hinges is 0.86…0.88, and distance between central and upper lever hinges to distance between external hinges ratio is 0.34…0.36, tie-rod length is approximately equal to distance between lever external hinges, and on frame central section, symmetrically relative to tool longitudinal axis supports are arranged, which height is equal to double height of hinge location above frame, connecting frame central and side sections.

EFFECT: such design solution provides for simplified tool transfer into transport position from working and vice versa, higher efficiency of tiller and more complete removal of weeds.
