Material processing screen plant drive system

1. A mobile material processing vibrating screen, comprising:

a vibrating screen, of a type being configured to be towed by a semi-tractor, and with a predetermined travel width dimension;

a railing coupled to said vibrating screen which is sized and located to inhibit a maintenance worker from falling;

a screen drive system operatively coupled to said vibrating screen, said screen drive system configured with:

a drive motor, which is disposed at least partially under the vibrating screen;

a sheave, having a bearing being supported by a shaft;

a belt, coupling the sheave and the drive motor;

a drive shaft coupled to a first joint;

a second joint, which is coupled to an opposing end of the drive shaft and to said sheave;

a ball bearing;

wherein said drive motor is an electric drive motor system;

an adapter;

wherein said adapter is coupled to a hub and to said first joint which is coupled to said drive shaft;

said second joint being coupled to said opposing end of the drive shaft; and

a stub-shaft and said ball bearing.

2. The vibrating screen of claim 1 wherein said first joint is a universal joint.

3. The vibrating screen of claim 2 wherein said screen drive system is configured so as to:

drive the vibrating screen; and

without being disabled or folded, be configured to not contribute to a failure to attain said predetermined travel width dimension.

4. The vibrating screen of claim 1 wherein said ball bearing is a double row ball bearing.

5. The vibrating screen of claim 1 wherein said screen drive system is configured so as to:

drive the vibrating screen; and

without being disabled or folded, be configured to not contribute to a failure to attain said predetermined travel width dimension.

6. The vibrating screen of claim 1 wherein:

said adapter is an adapter plate which is coupled to:

said hub, which is a ring feeder hub; and

to said first universal joint which is coupled to said drive shaft.

7. The vibrating screen of claim 6 wherein said ball bearing is a double row ball bearing.

8. The vibrating screen of claim 7 wherein said first joint is a universal joint.

9. A mobile material processing vibrating screen, comprising:

a vibrating screen with a predetermined travel width dimension;

a railing coupled to said vibrating screen which is sized and located to inhibit a maintenance worker from falling;

a screen drive system operatively coupled to said vibrating screen, said screen drive system configured with:

a drive motor, which is tucked at least partially under the vibrating screen;

a sheave, having a bearing being supported by a shaft;

a belt, coupling the sheave and the drive motor;

a drive shaft coupled to said sheave;

an interface which includes an adapter;

a bearing;

wherein said drive motor is an electric drive motor system;

said screen drive system further being configured to drive the vibrating screen without needing to be folded or disabled to attain said predetermined travel width dimension; and

wherein said adapter is coupled to a hub and to said drive shaft.

10. The mobile material processing vibrating screen of claim 9 further comprising:

a stub-shaft and; a first clip which retains an interior diameter (I.D.) of the bearing and a second clip which retains an outside diameter (O.D.) of the bearing.

11. The mobile material processing vibrating screen of claim 9 where said drive shaft is coupled through a first universal joint to said sheave.

12. A method of processing material with a vibrating screen at multiple locations comprising the steps of:

providing, at a first location, a vibrating screen, of a type being configured to be towed by a semi-tractor, and which has a screen drive system with:

a drive motor, which is located at least partially under the vibrating screen;

a sheave, having a bearing being supported by a shaft;

a belt, coupling said sheave and said drive motor;

a drive shaft coupled to a first joint;

a second joint, which is coupled to an opposing end of the drive shaft and to said sheave; and

operating said vibrating screen at said first location;

transporting, with said semi-tractor, said vibrating screen to a second location without folding said screen drive system; and

operating said vibrating screen at said second location.

13. The method of claim 12 wherein said bearing is a double row ball bearing.

14. The method of claim 13 wherein said first joint is a universal joint.

15. The method of claim 14 wherein said step of transporting is done by coupling said semi-tractor to a portion of said vibrating screen and pulling the vibrating screen on a roadway.
