Problems solved by technology

[0005]The problem with this method is that the accelerator is driven at a fixed speed set to achieve crop flow over a large operating distance, This operating distance is typically the distance from the nozzle exit to the container driving behind the harvester

Embodiment approach

[0038] Referring now to the accompanying drawings, and more particularly to figure 1 , shows an exemplary embodiment of a harvesting vehicle 10 in the form of a forage harvester 10 that directs a crop stream CS along a crop trajectory 12 to a receiving vehicle 14 towed by a tractor 16 .

[0039] Now, again refer to figure 2 , shows a side view of forage harvester 10 having wheels 18 , chassis 20 , header 22 , spray tube 24 and operator cab 26 . The wheels 18 carry a chassis 20 in which in turn a header 22 is supported. Heading deck 22 is selected to harvest—ie, cut and gather—crop CP from the field as forage harvester 10 travels in a forward direction. Harvested crops are processed and cut into small pieces for storage in silos and eventual feeding to livestock. Crop stream CS is directed along trajectory 12, as figure 1 The longitudinal direction in is shown in the rearward direction for efficient and uniform loading of the receiving vehicle 14 by sending the crop stream...

Abstract

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). Thesensor (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 ofthe 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 thevariable 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).

Description

technical field [0001] The present invention relates to a crop discharge rate control for use with a forage harvester. Background technique [0002] A forage harvester is a machine that cuts crops collected from the field into small pieces to produce livestock feed. In the case of primarily leaf crops such as pasture or alfalfa, these will be pre-cut and left to dry in the sun so that only the crop needs to be collected by the harvester. For other crops, such as corn, forage harvesters may also be equipped with headers for cutting upright crops. [0003] The crop—whether it's cut corn or gathered pasture—feeds into a rotating drum or knives that shred the product. The momentum of the crop (such as corn) from the crop processor or the pasture from the knives, as appropriate, brings the crop into the accelerator or thrower, which then pushes it up the pylon to the exit spray. pipe through which it is discharged into a wagon or trailer which may be towed by another vehicle t...
