摘要:
A harvesting vehicle including a cleaning section including a blower and at least one sieve. The sieve is configured to transport a layer comprising a mixture of grain kernels and residue material towards an exit edge of the sieve so that kernels fall through openings of the sieve and the residue remains on the sieve until it is ejected from the sieve by crossing the exit edge. The sieve may be subject to a grain loss, including a sieve-off loss and a blowout loss. The cleaning section further includes a sensor configured to determine whether the blowout loss or the sieve-off loss is a highest contributor to the grain loss. The cleaning section may also include a grain loss detector configured to measure the sieve-off loss and at least a portion of the blowout loss and a blowout sensor mounted above the sieve for measuring the blowout loss.
摘要:
A cleaning section of an agricultural harvester. The cleaning section including a sieve, a plurality of load sensors, and a sieve slope compensating system. The sieve is positioned in the harvester to receive crop material from a threshing section. The plurality of load sensors are coupled to the sieve. The load sensors are configured to produce signals representative of a distributed load of the crop material on the sieve. The sieve slope compensating system is configured to tilt or side shake the sieve dependent upon the signals.
摘要:
An agricultural combine (20) including a chassis (22), at least one cage (36) carried by the chassis (22), and a rotor (38) configured to rotate about an axis (68) within the cage (36). The rotor (38) and cage (36) being a rotor (38)/cage (36) assembly. There are a plurality of vanes (64) movably coupled to an inside surface of the cage (36), and there is a controller (74) that executes the steps of a method for controlling crop material speed through the rotor (38)/cage (36) assembly. The method includes the steps of monitoring a grain loss of the combine (20); computing an engine power reserve value; and adjusting an orientation of a vane (64) coupled to the cage (36) responsive to the engine power reserve value and to the grain loss, a cleaning system load and/or a straw length.
