摘要 |
<p>SPREADER CONTROL A material unloader having a conveyor and a distributing unit includes a control assembly operative from the tractor or towing vehicle by a single hydraulic control. A jaw clutch is provided for engaging and disengaging the distributing unit drive and the power shaft. A variable speed pulley assembly is operable to engage and disengage the conveyor drive and power shaft and to vary the speed of the conveyor over a wide range of values. The jaw clutch and variable speed pulley assembly are simultaneously controlled by a cam operated shifter assembly. The cam is mounted on a control shaft along with a pawl and ratchet mechanism indexed by a hydraulic cylinder to sequentially establish various combinations of conveyor and distributing unit drive conditions, including a condition wherein the distributing unit is disengaged and the conveyor is operating at a relatively high speed for fast cleanout of the unloader.</p> |
