Roller with semi-hollow pneumatic tyres for agricultural machinery, notably a roller that can be combined with a seed drill or a ground preparation tool
First Claim
1. A roller of an agricultural machine that can be combined with a seed drill or a ground preparation tool, comprising:
- a tubular support structure of horizontal axis adapted to be rotatably mounted on a tractor-drawn support frame; and
a series of semi-hollow tires having a profile of a selected shape, which are threaded onto the tubular support structure, enabling a series of parallel furrows to be formed in the earth,wherein the tubular support structure comprises a framework made up of a plurality of bars joined together by two circular end cheeks between which these bars extend axially, and the tires are mounted on said bars of the framework to form an assembly that is connected for rotation and translation, andwherein the tubular support structure further comprises end flanges mounted on the end cheeks such that the plurality of bars do not pass through the end flanges, the end flanges being adapted to hold and axially grip the series of tires threaded onto said tubular support structure.

Abstract
This roller (10) comprises a tubular support structure (14) of horizontal axis (X-X) adapted to be rotatably mounted on a tractor-drawn support frame. A series of semi-hollow tyres with a dome-shaped profile are threaded onto this tubular support structure and enable a series of parallel furrows to be formed in the earth. The tubular support structure (14) comprises a framework formed by a plurality of bars (30) joined together by two circular end cheeks (32) between which these bars extend axially. The tyres (12) are mounted on the bars of the framework, forming with the latter an assembly that is connected for rotation and translation.
