In a grain unloading system for a combine harvester a grain bin includes a frame, the frame has a floor with a trough disposed therein. An unloading auger is disposed at least partially within the trough. An auger cover at least partially covers the auger. The auger cover has a hat for a top portion of the auger cover and a pair of gates movable between the hat and locations on the floor that are proximal to the trough. A gate adjustment structure is coupled to the pair of gates to move the pair of gates relative to the auger. A control system is coupled to the gate adjustment structure and controls the gate adjustment structure. The gates are each provided with a plurality of external projections.

One or more techniques and/or systems are disclosed for automating the collection of product harvested from a site, such as grain from a field, and filling truck trailer for transport off site. These techniques can help operations that want to improve efficiency, while reducing field compaction and other issues related to weather or environmental conditions. A predetermined level of product can be identified for the target truck trailer, and an optimized fill method can be determined for filling the truck trailer efficiently using one or more mobile transport containers moving product from the field. A sensor array can detect an amount of the product disposed in the mobile transport container during transfer, and used to fill the mobile transport container to a predetermined level based at least on the optimized fill method. The mobile transport container is then used to fill the target truck-trailer container to its predetermined level.

A system is provided for controlling a grain cart relative to a grain truck. The grain truck includes a side edge extending between a front end and a rear end. The system comprises a ranging device and a controller. The ranging device is configured to determine a position and orientation of the side edge relative to the grain cart. The controller is configured to determine a path line parallel to the side edge, wherein the path line is a predetermined distance from the side edge, identify a goal point based on the path line, where the goal point a second predetermined distance from the front or rear end of the side edge, and plan a path for the grain cart to the goal point.

A system is provided for controlling a grain cart relative to a grain truck. The grain cart includes a grain tank and an unload auger configured to transfer crop material out of the grain tank. The grain truck includes a truck box extending from a first end to a second end. The truck box includes a top edge extending around the top of the truck box. The system comprises a ranging device and a controller. The ranging device is configured to identify a distance to the top edge of the truck box and identify a distance to an area in the truck box. The controller is configured to determine a position of the grain cart relative to the grain truck, and determine whether the grain cart is positioned near the first end of the truck box. If the controller determines that the grain cart is positioned near the first end of the truck box, the controller is configured to determine a fill level in the area based on the distance to the top edge of the truck box and the distance to the area in the truck box, determine whether the fill level exceeds a threshold, and if the controller determines that the fill level does not exceed the threshold, the controller is configured to start the unload auger.

A sugarcane harvester may include a base cutter configured to cut sugarcane, a chopping device in communication with the base cutter to receive the sugarcane cut by the base cutter, the chopping device configured to chop the cut sugarcane into billets, an elevator in communication with the chopping device, the elevator configured to transport the billets out of the sugarcane harvester, the elevator having a discharge end, a forward billet deflector beyond the discharge end of the elevator distant the discharge end, a rearward billet deflector proximate the discharge end and spaced from the forward billet deflector such that the billets fall between the forward billet deflector and the rearward billet deflector and a powered actuator to move the rearward billet deflector to adjust a discharge direction of the billets.

An improved grain unloader for unloading grain from a grain storage bin of a grain harvesting combine is terminated by a hood having a lower grain exiting opening terminating the unloader wherein the hood reversibly moves laterally outwardly for directing the trajectory of the grain flowing therefrom. The hood has a lower grain exiting opening terminating the unloader wherein the hood includes an upper stationary slanted wall and a lower extendable hood portion, wherein the upper stationary slanted wall directs the grain downwardly when the hood is retracted and downwardly, and outwardly when the hood is extended. A linear actuator is attached between the hood and the unloader. Drawer slides connect the unloader and the hood for movement of the hood.

An agricultural device for unloading of grain including an unloader conveyor includes a first enclosed housing having an inlet end including an opening for receiving grain. A second enclosed housing having an opposite outlet end includes a discharge opening through which the grain can be discharged. An unloader conveyor element extends through the housing between the ends and is operable for conveying the grain through the housing from the inlet end and discharging the grain through the discharge opening. The unloader conveyor element has a first unloader conveyor segment in operative association with a second unloader conveyor segment downstream of the first unloader conveyor segment. A directional transition region is positioned between the first unloader conveyor segment and the second unloader conveyor segment. At least a portion of the second housing near the directional transition region includes a region having reduced cross-sectional area.

An agricultural harvester has a header for harvesting a crop, an on-board container for storing the harvested crop, and a feeder adapted to receive the harvested crop from the header and provide the harvested crop to the on-board container. The agricultural harvester further has a transporter adapted to transport the harvested crop from the on-board container towards a distal end of the header; at least part of the transporter being mounted to the header or the feeder and a discharger in communication with the transporter and adapted to receive the harvester crop as transported by the transporter, at or near the distal end of the header, the discharger having a discharge outlet for discharging the harvested crop.

A harvester grain unloading auger may have auger flights within an unloader housing, wherein a discharge speed adjustment mechanism is coupled to the unloader housing to receive grain from the grain unloading auger at a first speed. The discharge speed adjustment mechanism discharges the grain at a second speed greater than the first speed.

An extendable and retractable conveyor includes a hopper for receiving agricultural product, and a housing having an inlet and an outlet that are separated by a fixed distance, the inlet being adjacent to the hopper for receiving the agricultural product from the hopper. The extendable and retractable conveyor also include a belt conveyor disposed within the housing for conveying the agricultural product from the inlet to the outlet, the conveyor defining a direction of conveyance; a hood connected to the outlet for deflecting the agricultural product relative to the direction of conveyance; and a movable spout that is slidably connected to a tube and disposed beneath the hood to receive the agricultural product from the hood, the movable spout being slidable in a direction parallel to the direction of conveyance to thereby extend or retract the conveyor.
