Device for the connection of a crushing tool to a rotor; agricultural crushing machine equipped with such a device

摘要

The grinding tool (13) is connected to the central web (11) of a rotor (4) of an agricultural vegetable grinding machine. It has a means (15) allowing the tool to occupy several work positions during rotor rotation with different trajectory radii corresponding to different working levels. The means comprise an intermediate support (16) to which the grinding tool is connected. The support is connected to the rotor central web by means of a first pivot (20) whose axis (21) is parallel to the rotor rotational axis. The intermediate support is also connected to the grinding tool by a second pivot (22) whose axis (23) is parallel to the first pivot axis. A locking system (55) locks the first pivot so as to fix the intermediate support on the central web in an angular position (52) far apart from the radial position.
