Hydraulic drive for a feed auger
First Claim
1. In an auger arrangement having a main auger, a feed auger operatively arranged with respect to the main auger such that particulate materials can be transported through the feed auger and the main auger, a support structure for supporting the main auger and the feed auger, and a mechanical drive means for driving the main auger from power derived from an external power source, the improvement comprising:
- a hydraulic assembly mounted on the auger arrangement, the hydraulic assembly including a hydraulic motor responsive to pressurized hydraulic fluid for driving the feed auger, and a hydraulic pump for supplying pressurized hydraulic fluid to the hydraulic motor; and
connecting means operatively connecting the hydraulic pump to the mechanical drive means to drive the feed auger.

Abstract
A feed auger for transporting particulate material to a main auger which has a drive shaft driven by a direct mechanical connection from a PTO of a tractor vehicle. The feed auger is attached to a hopper at one end and pivotally mounted to the main auger at the other end such that particulate material entering the hopper is transported through the feed auger and into and through the main auger. The feed auger is driven by a hydraulic system operated from the drive shaft of the main auger, the hydraulic system providing independent control of the operation of the feed auger.

4. An auger arrangement for transporting particulate material comprising:
-
a main auger having a main auger tube, a helical main auger flight rotatably mounted within said main auger tube, a discharge spout at an upper end of the main auger tube, and an inlet at a lower end of the main auger tube; frame means for supporting the main auger tube with the upper end raised relative to the lower end; drive coupling means for connection to an external power source; first mechanical connection means communicating drive from the drive coupling means to the main auger flight; a feed auger having a feed tube, a helical feed auger flight rotatably mounted within said feed auger tube, and a downwardly depending discharge spout at a discharge spout at a discharge end of the feed auger flight operable with the inlet of the main auger tube; and hydraulic drive means mounted on the auger arrangement, the hydraulic drive means including a hydraulic motor responsive to pressurized hydraulic fluid for driving the feed auger flight, a hydraulic pump for supplying pressurized hydraulic fluid to the hydraulic motor, and a hydraulic reservoir for storing and supplying hydraulic fluid to the hydraulic pump, and second mechanical connection means operatively connecting the hydraulic pump to the drive coupling means for driving the feed auger flight. - View Dependent Claims (5, 6, 7, 8, 9, 10, 14)
