ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a rear scrub dual drive means for a sugar beet harvester which allows the user to quickly and conveniently change the relative speeds of the independently driven rear scrub chains.
As sugar beets are being harvested they are cleaned and scrubbed by a sugar beet harvester. The sugar beets are picked up by the harvester and first transported upon cleaning rollers and then transported via a conveyor system of two endless conveyors, both of which move vertically and as they do so, the sugar beets are moved vertically between the back run of the first conveyor and the front run of the second conveyor. Both the back run of the first conveyor and the front run of the second conveyor move upwardly, and as they do so the sugar beets are scrubbed upon the spaced elongate member which comprise the conventional belted chain conveyor system.
2. Description of the Prior Art
Generally the two conveyors move at different speeds to effect the scrubbing of the sugar beets. Prior to the present invention, the conveyors were driven by an endless chain carried about drive sprockets mounted to the drive shaft, which rotate the conveyors. One of the conveyors would have either a larger or smaller sprocket than the other conveyor so that the conveyors would move at different speeds to effect the scrubbing process. In order to change the speeds of the conveyors, one or the other of the drive sprockets would have to be removed from the drive shafts and a different sized drive sprocket or sprockets would have be to fastened to the particular drive shaft or shafts. This process is time consuming and costly, because the drive chain in addition to the drive sprocket would need to be taken off and then put back on again.
The present invention eliminates this time consuming and costly process and allows the user to change speeds on the go. The conditions and types of sugar beets may vary even within the same field which may require the user to change the speed of the conveyors to effect the kind of scrubbing necessary at any particular time.
SUMMARY OF THE INVENTION
The present invention relates to a rear scrub dual drive means for a sugar beet harvester which includes a functionally-independent first actuator which is mounted to a conventional first drive shaft and a functionally-independent second actuator which is mounted to a conventional second drive shaft, both of which extend rotatably through and between a pair of conventional spaced-apart walls of the frame of a sugar beet harvester.
The first actuator, when energized, rotates the first drive shaft which rotates a conventional endless first conveyor which is carried about a first drive sprocket mounted to the first drive shaft and further carried about a plurality of first sprockets and first rollers mounted to a plurality of first support shafts, all of which rotatably extend through and between the spaced-apart walls near the front end thereof with the back run of the endless first conveyor moving upward and the front run moving downward.
The second actuator, when energized, rotates the second drive shaft which rotates a conventional endless second conveyor which is carried about a second drive sprocket mounted to the second drive shaft and further carried about a plurality of second sprockets and second rollers mounted to a plurality of second support shafts all of which rotatably extend through and between the spaced-apart walls near the back end thereof with the front run of the endless second conveyor moving upward and the back run moving downward. The sugar beets are scrubbed and moved between the back run of the first conveyor and the front run of the second conveyor.
One objective of the present invention is to provide a rear scrub dual drive means for a sugar beet harvester which allows the user to quickly and conveniently change the speeds at which the conveyors move to effect the best possible scrubbing of the sugar beets.
Another objective of the present invention is to provide a rear scrub dual drive means for a sugar beet harvester which allows the user to adjust the speeds of the conveyers independently of one another without the user having to change the size of the sprockets on the drive shafts.
Yet, another objective of the present invention is to provide a rear scrub dual drive means for a sugar beet harvester which eliminates the user having to take anything apart on the rear scrub in order to effect speed changes in the conveyors.
Other objects and advantages of the present invention will become obvious to the reader and it is intended that these objects and advantages are within the scope of the present invention.
To the accomplishment of the above and related objects, this invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specific construction illustrated and described within the scope of the appended claims.
