Title: Appliance for the chemical treating of cereal seeds
IPC: A01C1/08
Filed: 1987-06-11
Abstract: The invention relates to an appliance for the chemical treating of cereal seeds. The mixer 4 is made up of a cylinder in the form of a drum whose casing 24 can rotate about the mixing shaft 10 and is supported by the latter on two bearings 25. This shaft 10, equipped with vanes 23, rests on the framework 3 via two bearings 9, and mixes the contents thus creating an inertia which tends to turn the casing of the drum. The weighing/mixing by batches of approximately 20 kilos is obtained according to the Roberval balance principle. A chassis 3 mounted on a pivot 26 represents the balance arm of the Roberval balance. The plates are represented, on the one hand, by the mixer 4 placed on one end of the chassis and, on the other hand, by the drive equipment 5 which corresponds to the weight of the mixer and its contents and is placed on the end opposite the mixer. The mixing starts at the same time as the filling of the mixer, which takes place via its upper orifice 22 from a hopper 1 equipped with a capped valve 11. The latter is automatically cut out by a mechanism connected to the tilting of the chassis.
