SELF-PROPELLED FODDER CROP HARVESTING COMBINE Russian patent published in 2002 - IPC

FIELD: agriculture. SUBSTANCE: combine has wheeled frame with three-dimensional front part. Frame comprises side and traverse members. Engine, feeding and grinding units and carrier wheels drive are mounted on frame. First lower traverse member adapted for connecting front ends of lower side members is joined with second lower traverse member by means of at least two longitudinal beams. Upper traverse member is attached to lower side members through struts. Grinding unit is fixed through detachable joint on longitudinal beams. Grinding unit casing is connected to upper traverse member by means of detachable joint. Carrier wheel drive is made in the form of two reducers equipped with input shafts and mounted on lower side members. Reducers are joined through transmission with speed- change box fixed to supporting plate and equipped with two output shafts. Transmission is made in the form of at least one transmission shaft comprising compensating couplings and adapted for connecting speed-change box output shaft with reducer input shaft. One coupling is mounted for compensating shafts angular displacements, while other coupling for compensating axial displacements. EFFECT: improved operating characteristics and enhanced reliability in operation. 15 cl, 13 dwg
