摘要:
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.

An agricultural vehicle includes a chassis; a threshing and separating assembly carried by the chassis; and a cleaning system carried by the chassis and configured to receive crop material that has passed through the threshing and separating assembly. The cleaning system includes a pan configured to receive crop material from the threshing and separating assembly on a pan surface and to shake in a fore-to-aft direction; at least one sieve located below the pan and configured to shake in fore-to-aft and lateral directions, the sieve including a sieve surface configured to receive crop material from the pan; and at least one divider associated with and extending at least 3 centimeters above at least one of the pan surface and the sieve surface.

A cleaning system for an agricultural combine harvester includes a sieve having a periphery and an interference member located at the periphery. A chaffer frame carries the sieve, and includes a clamp with a pair of spring fingers positioned on either side of the interference member, thereby retaining the sieve within the chaffer frame.

A combine side-shaking control system includes a sieve for separating crop material from other materials and a movable side-shaking mechanism coupled to the sieve and configured to move the sieve in a side-to-side motion. The control system also includes also includes first and second grain loss sensors configured to sense amounts of grain loss from separate portions of the sieve. The control system further includes a controller configured to: (i) receive a first grain loss value corresponding to the sensed first amount of grain loss and a second grain loss value corresponding to the sensed second amount of grain loss; and (ii) cause the side-shaking mechanism to control movement of the sieve in the side-to-side motion based on at least one of the received first grain loss value and the received second grain loss value.

A spreader arrangement for an agricultural harvester includes a windrow chute having a first position for building a windrow in which the chute angles downwardly from a proximal edge to a distal edge of the chute, and a second position for cleanout of the chute in which the chute angles downwardly from the distal edge to the proximal edge of the chute. Adjustment from the first position to the second position and back to the first position can occur automatically when the combine is operating but not currently harvesting, such as during the time period between when a harvesting swath is completed and the next harvesting swath is commenced, so that accumulated crop residue material can be dislodged from the windrow chute without disrupting harvesting or the windrow building process.

A sieve arrangement for an agricultural combine harvester includes a sieve frame for carrying a sieve, a side shaker arm, and a plurality of elongate structural members. The sieve frame includes a first side frame member and a second side frame member. The side shaker arm is connected with the first side frame member. Each structural member has a first end connected to the side shaker arm, and a second end connected with the second side frame member.

An agricultural harvesting system including a chassis, an agricultural product moving device coupled to the chassis, an airflow system, a cleaning system and an airflow characterizing system. The cleaning system is configured to receive the agricultural product from the moving device. The cleaning system is configured to receive an airflow from the airflow system. The airflow characterizing system is at least partially positioned in the airflow, and is configured to measure an airflow profile across the cleaning system. The airflow characterizing system includes a plurality of sensors that determine airflow by measuring a thermal transfer from the sensors to the airflow. The airflow characterizing system being configured to maintain a substantially constant electrical resistance of the sensors as the airflow varies. The airflow characteristics are measured in the cleaning system and are used to improve the cleaning capacity of the harvesting system.

A spreader arrangement for an agricultural harvester includes a pair of spreader discs, at least one cover plate and a windrow chute. The spreader discs are generally horizontally arranged and rotatable in a counter rotating manner. Each cover plate is positioned at a location above a respective spreader disc, and is operable to inhibit a flow of crop material to the respective spreader disc when positioned above the respective spreader disc. The windrow chute has an entrance end positioned below the pair of cover plates and above the pair of spreader discs, whereby crop material is discharged from the top of the cover plates into the windrow chute.
