MOUNTED COMBINED MACHINE Russian patent published in 2015 - IPC A01B73/04 A01B49/02 

FIELD: transport.

SUBSTANCE: proposed machine comprises articulated three frame sections with working tools. Front and second sections (1) and (7) are coupled by hydraulic cylinder (16) for upward turn of second section (7) on pins (9) of articulation with front section (1). Front and third sections (1) and (13) are coupled by con-rod (17) with pins (18) and (19) of these sections. Con-rod (17) pin axle (18) is located ahead of and above pin (10) of articulation between first and second sections (1) and (7). Pin (19) of articulation between con-rod (17) with frame third section (13) is fitted on its top end ahead of pin of articulation between second and third sections (7) and (13). Pin (19) has crosswise bore to receive con-rod and can turn about its axis. In run-in position, distance between remote points of pins (18) and (19) for con-rod (17) is smaller than its working length (S), In working position, said distance equals the con-rod (17) working length while angle between second and third sections (7) and (13) is not smaller than 90 degrees.

EFFECT: reliable conversion from in-run to working position.
