Abstract
The machine comprises a given number of roller pairs respectively connected to the machine frame by a linking part (32). The linking part (32) of each roller pair is adapted so as to enable the rollers (12a, 12b) to incline freely about a first roll axis (YY′) perpendicular to and coplanar with the longitudinal axis (XX′) of the rollers and about a second axis (HH′) parallel to the pitch axis of the frame (10), no matter what deformations of the road or terrain are encountered. Application in particular to seed drills for agricultural machines.
Claims12
Agricultural machine comprising a support frame and several rollers connected to said support frame, each roller being equipped with a set of pneumatic tyres engaging round a tube and having respective dome-shaped, circumferential profiles able to form a set of furrows in the ground, and having a number of roller pairs respectively connected to the machine frame by a linking part, the linking part of each roller pair being adapted to enable the rollers to incline freely about a first roll axis perpendicular to and coplanar with the longitudinal axis of the rollers and about a second axis parallel to the pitch axis of the frame, no matter what road or terrain deformations are encountered, and
- wherein each tube of a roller pair is mounted on a hub at the end of an axle, said axle having a longitudinal axis coinciding with the longitudinal axis of the rollers.
