Abstract

A screen drive for a mobile material processing screen which can be at a travel width without having to fold or disable the screen drive. The screen drive system includes a drive motor, which is tucked at least partially under the vibrating screen; a sheave, having a double row ball bearing being supported by a shaft; a belt, coupling sheave and drive motor; a drive shaft coupled to a first universal joint, and a second universal joint, which is coupled to an opposing end of the drive shaft and to sheave.

First claim

We claim:

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.
