Combine harvester - with sieve and transverse conveyor for threshold grain having transverse conveyor positioned between sieve and shaker

摘要

Underneath the shaker unit is a preparation pan next to a sieve. Between the shaker and the preparation pan is a transverse conveyor in the form of a conveyor belt stretched between two rollers with very small diameter. One roller is driven by means of a belt by an electric motor in which is a potentiometer resistor with pick-up contact. The pickup contact is coupled with a step-by-step system connected to a meter positioned in a diagonal branch of a bridge circuit formed by a Wheatstone bridge. Beneath the two sides of the sieve are transmitters indicating the grain through-flow.
