TIRE ELEMENT FOR AN AGRICULTURAL TOOL INCLUDING A RIGID BASEPLATE
The invention relates to a pneumatic element for an agricultural tool comprising a non-inflated tire with a capacity to deform to promote the separation of the earth. However, increasing the capacity of the tire to deform is not sufficient to achieve a functional agricultural tool. The tire must be rigid enough to work the ground and the pneumatic elements must be resistant to shocks and the efforts exerted on them. This invention solves these problems by proposing an agricultural tool element comprising an uninflated tire with a tread and a pair of sidewalls each connected to the tread. The element comprises a rigid base through which the tire is mounted on a rotary support. The sidewalls are each overmolded on a peripheral portion of the rigid base. The base thus has the rigidity and strength required to withstand the forces and shocks that occur when the tool works.

Semi-hollow pneumatic tire and associated wheel rim, notably for agricultural machinery
A pneumatic tire of the semi-hollow type includes a casing having an uninflated inner volume and including an inner wall provided with a retaining bead and a convex outer wall forming the tread of the tire, the inner wall and the outer wall of the tire being connected by two annular borders. The inner wall of the tire is concave so as to surmount a convex outer wall of the peripheral seat of a rim of a wheel, this outer wall being provided with a peripheral slot adapted to accommodate the retaining bead of the tire.
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.
