  • Patent number: 10959380
    Abstract: A sieve for a cleaning system of an agricultural harvester includes: a sieve frame defining a top side; adjustable louvers carried by the sieve frame and defining apertures; an adjustment bar coupled to the adjustable louvers such that displacement of the adjustment bar changes a size of at least some of the apertures; and an adjustment assembly. The adjustment assembly includes: an adjustment arm coupled to the adjustment bar and pivotable relative to the sieve frame such that pivoting of the adjustment arm about a pivot axis displaces the adjustment bar. The adjustment arm carries a locking pin. A shaft is disposed on the top side and coupled to the adjustment arm. Displacement of the shaft from a first position to a second position causes a corresponding displacement of the locking pin from a locking position to an adjustment position.

  • Publication number: 20200060087
    Abstract: An elevator assembly for a harvester may include an elevator extending within between proximal and distal ends. The elevator may be configured to carry harvested crops between its proximal and distal ends. The elevator assembly may also include a storage hopper at a location adjacent to the distal end of the elevator. The storage hopper may include a rear deflector and a hopper gate. The hopper gate may be movable between a discharge position, at which the hopper gate exposes a discharge opening of the storage hopper, and a storage position, at which the hopper gate covers the discharge opening to prevent harvested crops from being discharged from the elevator assembly. Additionally, when the hopper gate is moved to the storage position, the hopper gate and the rear deflector may at least partially define a storage volume adjacent to the distal end of the elevator for storing the harvested crop.

  • Publication number: 20190373814
    Abstract: A debris removal system for an agricultural harvester may include a chopper assembly configured to chop harvested crops into billets; an elevator having an elevator inlet that receives a stream of billets from the chopper assembly; and an extractor positioned adjacent the elevator inlet that is configured to remove from the harvester debris separated from the billets. A fan assembly may be positioned between the chopper assembly and the elevator inlet and may include a fan and a fan discharge outlet. The fan assembly may blow a stream of air through the stream of billets and toward the extractor to separate the debris from the billets for removal by the extractor. Moreover, the fan has a diameter that is approximately twice a height of the fan discharge outlet. Other debris removal systems and methods for removing debris from harvested crops also are provided.

  • Patent number: 10412888
    Abstract: A method for operating a harvester may include initially operating the harvester in a discharge harvesting mode such that harvested crops are conveyed to a distal end of an elevator of the harvester and subsequently discharged from the harvester through a discharge opening defined by a storage hopper located at the distal end of the elevator. The method also includes reducing an operating speed of the elevator and blocking the discharge opening defined by the storage hopper upon receipt of an operator input associated with operating the harvester in a storage harvesting mode. Additionally, the method includes actively adjusting the operating speed of the elevator based on a crop flow parameter of the harvester as the harvested crops expelled from the distal end of the elevator are being stored within a storage volume of the storage hopper.

  • Patent number: 10123486
    Abstract: An agricultural harvester includes a grain processing section having a sieve assembly. The sieve assembly includes right and left frames interconnected by a cross member. The cross member has end castings securable to the right and left frame members. An elongated U-shaped sheet metal member extends between the castings. An elongated slot at each of the U-shaped sheet metal member terminates in a circular hole. The slot and circular hole accommodate variations in forming tolerances for the U-shaped sheet member and dissipate stresses.
