US 4,070,059 A · Grain trailer

Abstract

A low profile material carrier which, in a preferred embodiment, comprises a grain trailer with a low rear opening for dumping. Most of the load, approximately 80%, dumps through the opening under the influence of gravity. The remaining portion of the load is assisted through the opening by a unique vibrator assembly attached to an interior sloping surface of the trailer. The assembly includes an elongated vibrator bar, which extends the length of and is parallel to the downwardly sloping surface of the trailer which leads to the opening. A motor driven shaft having a plurality of eccentric weights positioned thereon is located intermediate the vibrator bar and the inclined bottom surface and is attached to the bar by a plurality of bearings. Upon actuation of the motor, the shaft, and hence the bar, are vibrated so as to serve as a direct stimulus for the emptying of the material in contact therewith.
