Abstract
This thesis describes the development of an automatic control
system which controls the forward speed of a self propelled combine in
relation to the load on the cylinder. The purpose of the system is to
keep the feed rate of the combine constant in order to increase the
machine's efficiency. The system can be adjusted according to the crops
and fieled conditions encountered.
Field tests were carried out in wheat, oats, and barley at
several moisture and yield levels. Tests indicated that the system was
able to control the feed rate at a preset level, within the range of the
system dead zone. On the basis of these tests and previous grain loss vs
feed rate tests, it is concluded that the control system is able to keep
the grain losses from the combine at a preset level, within a range determined
by the system characteristics.
The system is low in cost, simple to operate, and does not interfere
with the control or operation of any other combine mechanisms.
