摘要:
A device for adjusting the opening width of vibrating sieves in a cleaning mechanism of combine harvesters is arranged on and vibrates directly with the sieves or the sieve frame. The device includes an electric-motor-driven adjusting mechanism which actuates in a direction along an axis which differs from the direction in which the sieve is vibrating. A detector is activated when a particular sieve opening width is achieved. When the detector is activated, the particular opening width is associated with a position of the adjusting mechanism as measured by a position sensor, thereby allowing calibration of further adjustments to the sieve opening.

A self-propelled combine harvester has a machine housing, and a suction fan configured so as to convey at least one stream of material out of the machine housing, so that it causes the stream of material to be distributed across a spreading width.
摘要:
A combine harvester has at least one cleaning device which includes at least one sieve and one cleaning fan, at least one conveyor device for conveying at least a portion of the crop material that exits the cleaning device into a higher region of the combine harvester and including at least one elevator having a lower intake region and an upper transfer region, the crop material being conveyed in the elevator via conveyor plates which are situated on a circulating chain, and the elevator includes, in its lower region, at least two interspaced deflection axles for the circulating chain, which are oriented transversely to the longitudinal extension of the combine harvester.
摘要:
A combine harvester has a mounted chopper with a wide-distributor discharge, designed such that the need for impeller blowers for distributing the chopped material across the entire cutting width of the combine harvester is eliminated.In the mounted chopper according to the invention, the latter consists of the two chopper units whose shafts carrying the chopper blades are at an obtuse angle to each other and cooperate with corresponding counterblades. Each chopper unit is equipped with an input funnel so that the straw is chopped completely. To distribute the chopped material, each chopper unit is equipped with an ejection fitting, increasing in cross-section towards the rear end.The mounted chopper is particularly suitable for combine harvesters with a wide cutting width.
