FIELD: transport.SUBSTANCE: harvesting machine includes executive devices mounted on frame resting on self-adapting wheels (24). The wheels are located in the middle part of the machine and connected with its frame by arms (13 and 14) of parallelogram mechanism. Axes of arms rotation are parallel to horizontal plane, herewith, one of arms of each parallelogram mechanism is additionally connected with machine frame by hydraulic cylinder (16). Bearing elements of frame are made as two connected by side members transversal hollow flat-topped arcs located in series. Vertical part of front arc (1) in its horizontal cross-section is rectangular with cross-section walls orientation along and across the machine. Lower arm (13) of parallelogram mechanism is provided with lug (15) for hydraulic cylinder (16) attachment, and upper arm (14) is made cranked, and bracket (11) for its mounting is located on rear wall of front arc (1). Articulation pivots connecting arms (13 and 14) of parallelogram mechanism with frame are oriented at sharp angle (?) to transversal-vertical plane of the machine.EFFECT: while keeping minimum dimensions and metal consumption of frame, getting wider possibilities for transversal manoeuvring and machine clearance change thus improving its manufacturing and operational characteristics.2 dwg |
