FIGURE C-2 Cleaning Function Diagram
Samples are bagged from the discharge of the cyclone. An optional volumetric cylinder can be
used to take quantitative yield data on samples before bagging. An optional weigh hopper can
perform automatic weight and moisture tests before bagging. Tests are completed in the weigh
hopper as the next plot is delivered into the cyclone seed hopper. This two-stage sample data
gathering technology allows harvesting plots at a high rate of speed, and still allows automatic
weight, moisture and data storage equipment to function with its recommended time requirements.
ROW CROP HEAD FUNCTION
A Row Crop Head functions by first pinching the plant between two opposing convoluted gathering
belts, while the plant is cut off by a rotating knife. The gathering belts transfer plant material onto
a chevron style belt in the throat. This belt carries the material up the throat to an upper pinch
belt. The upper pinch belt feeds the material into the threshing chamber. It is important to note
that the speed of the gathering belts should match or just exceed the ground speed. If the belts
run too slowly the plant can be pushed over forward increasing the chances of feeding problems.
If the belt runs too fast the plant is jerked into the belts, possibly knocking off seed and dragging
dirt and debris into the head.
