Abstract:
1. An appliance for rapidly vibrating test tubes containing samples to be ground up, which comprises an electric motor for driving rotation of a disk that is provided with an eccentric pin, wherein the test tubes are carried by a support substantially parallel to the eccentric pin and are oriented substantially perpendicularly to the eccentric pin, which eccentric pin is connected to a fixed baseplate via a hinge center having a first and a second mutually perpendicular axes of rotation, the first axis of rotation being substantially parallel to the eccentric pin and connecting the support at a first end to the second axis of rotation of the hinge center that prevents the support from moving in rotation about a third axis of rotation perpendicular to the first and second axes of rotation, and wherein the support is connected to the eccentric pin by a link having: a first end connected to the support by a fork-type connection which defines a Cardan type coupling with the support and is adapted for imposing a vibratory movement on said support about both said first and second axes of rotation, and a second end connected to the eccentric pin.
