Roller assembly for agricultural machinery |
摘要 |
A roller assembly for agricultural machinery is disclosed. The roller assembly includes at least one tube onto which tires are threaded, and two arms adapted to support the tube in rotation at both its ends. Each arm carries a suspension lever housed inside the tube and acted upon by a resilient recoil member. The suspension lever is mounted on the arm so as to be pivotable about a first rotation axis and supporting a shaft end which carries a flange fixed to the inside of the tube for the rotation of this tube about a second rotation axis parallel to the first rotation axis. The roller assembly applies particularly to the rollers of seed drills. |
