Patent ID: 7645065

Claim:
An experimental mixing device comprising: a driving source including a driving motor; an eccentric member having a central axis, said eccentric member including a base portion and an eccentric axle having an eccentric axis which is eccentric with the central axis; a secondary axle rotatable about a drive axis, the secondary axle being drivably connected to the driving source so as to be rotatably driveable by the driving source, said base portion of said eccentric member being mountable in a fixed mounting position at an upper portion of said secondary axle while oriented in selectively different circumferential positions relative to the secondary axle so as to be non-rotatable with respect to said secondary drive axle when mountably received in a respective one of said different circumferentially oriented positions, said central axis being eccentric with said drive axis when said eccentric member is mounted in said fixed mounting position; a mixing member configured to perform a mixing operation; a support member provided below the mixing member and configured to support the mixing member; a base provided below the support member and configured to enclose the driving source; and a control device which is positionally interposed between the eccentric member and the secondary axle, said control device including an arm, the eccentric member being mountably receivable on the arm, rotation of the eccentric axle adjusts a tilt angle of the eccentric member.
