摘要
A crop discharge speed control system (30) for a harvesting vehicle (10) having a crop accelerator (32) and a spout (24) that receives crop material and directs the crop material to a targeted destination. The crop accelerator (32) imparts an increased velocity to the crop material. The control system (30) includes a crop velocity sensor (50), a controller (40) and a variable speed drive (36). The sensor (50) is coupled to the spout (24) of the vehicle (10) for the detection of a velocity of the crop material in the spout (24), the sensor (50) produces a velocity signal (VS) representative of the velocity of the crop material. The variable speed drive (36) is drivingly coupled to the crop accelerator (32). The controller (40) varies the speed of the crop accelerator (32) by controlling the variable speed drive (36), as it controls the variable speed drive (32) to maintain a selected velocity of the crop material dependent upon a modulation of the velocity signal (VS).
