Mixing assembly

1. A mounting assembly for a container, comprising:

a drive coupler shaped to engage a coupling member on a drive shaft; the drive coupler having a groove to engage a locking pin on the coupling member; the drive coupler within a male funnel;

a cover for the container, the cover defining an aperture to allow passage of the shaft;

a drive shaft partially covered by the drive coupler, the drive shaft rotatable by a motor; and

a female funnel positioned within the cover to receive the drive coupler and guide the drive coupler to the coupling member.

2. The mounting assembly of claim 1 wherein the drive coupler is shaped to be received by the funnel.

3. The mounting assembly of claim 1 wherein the drive coupler and motor are secured to a rocking frame configured to use a surface on the container as a fulcrum.

4. The mounting assembly of claim 1 wherein the cover comprises an extension on an exterior of the cover, and the drive coupler further comprises a locking member securable to the extension.

5. The mounting assembly of claim 3 wherein the cover is sized to serve as a guide for positioning of the rocking frame for alignment of the drive coupler and coupling member.

6. A mounting assembly, comprising:

i. a drive coupler shaped to engage a coupling member on a shaft positionable within a container, the container defining an aperture to allow passage of the shaft, wherein the drive coupler is mounted to a moveable frame;

ii. a first funnel positioned within the aperture to receive the drive coupler and guide the drive coupler to the coupling member,

wherein the moveable frame is moveable from a first position wherein the drive coupler is not positionable to receive the coupling member to a second position wherein the drive coupler is positionable to receive the coupling member, and

wherein the frame further comprises an actuator, which when actuated, allows pivoting of the drive coupler.

7. The mounting assembly of claim 6 wherein the actuator is configured to actuate when the drive coupler is positionable to be received by the funnel.

8. The mounting assembly of claim 6 wherein the drive coupler is rotatable by a motor.

9. The mounting assembly of claim 8 wherein the frame further comprises a plurality of concave rollers sized and positioned to roll along at least two spars on the container.

10. The mounting assembly of claim 9 wherein the container comprises a neck surrounding the aperture.

11. The mounting assembly of claim 9 further comprising a cover positionable within the aperture.

12. The mounting assembly of claim 11 wherein the cover comprises an extension on an exterior of the cover, and the drive coupler further comprises a locking member securable to the extensions.

13. The mounting assembly of claim 12 further comprising an impeller secured to the shaft.

14. A mounting assembly, comprising:

i. a drive coupler shaped to engage a coupling member on a shaft positionable within a container, the container defining an aperture to allow passage of the shaft;

ii. a first funnel positioned within the aperture to receive the drive coupler and guide the drive coupler to the coupling member,

wherein a mixer is configured to dissipate electrostatic charge.

15. A mounting assembly, comprising:

i. a drive coupler shaped to engage a coupling member on a shaft positionable within a container, the container defining an aperture to allow passage of the shaft;

ii. a first funnel positioned within the aperture to receive the drive coupler and guide the drive coupler to the coupling member; and

iii. a second funnel surrounding the drive coupler and configured to be received by the first funnel.

16. A mounting assembly, comprising:

a drive coupler shaped to engage a coupling member on a shaft positionable within a container, the container defining an aperture to allow passage of the shaft; the drive coupler positioned on a moveable frame moveable from a first position wherein the drive coupler is not positionable to receive the coupling member to a second position wherein the drive coupler is positionable to receive the coupling member; the frame comprising an actuator, which when actuated, allows pivoting of the drive coupler, the actuator actuatable when the drive coupler is pivotably alignable with the coupling member.
