摘要：
A crop discharge speed control system for a harvesting vehicle having a crop accelerator and a spout that receives crop material and directs the crop material to a targeted destination. The crop accelerator imparts an increased velocity to the crop material. The control system includes a crop velocity sensor, a controller, and a variable speed drive. The sensor is coupled to the spout of the vehicle for detecting a velocity of the crop material in the spout. The sensor produces a velocity signal representative of the velocity of the crop material. The variable speed drive is drivingly coupled to the crop accelerator. The controller varies the speed of the crop accelerator by controlling the variable speed drive, as it controls the variable speed drive to maintain a selected velocity of the crop material dependent upon a modulation of the velocity signal.
