A dust management system for an agricultural harvester includes a perforated tube extending transversely through a feeder housing of the harvester. The perforated tube has exhaust plenums at opposite ends directing any flow towards the ground over which an agricultural harvester operates. A longitudinal drive shaft mounts axial flow fans within the exhaust plenums and a drive shaft is driven through a pulley system so that rotation of the drive shaft induces flow through the perforated tube and out of the exhaust plenum.

In one embodiment, a system comprising an impervious bin skirt, the bin skirt comprising at least one section, a top portion of a first section of the bin skirt to couple to a side wall of the bin to shield a portion of a base of the bin from moisture penetration.

A working machine, movable on a substrate, comprises a sensor arrangement, wherein the sensor arrangement comprises: at least one sensor housing (24) with a sensor accommodation space (26) open via a detecting aperture (30), at least one sensor (28) arranged in the sensor accommodation space (26) of the at least one sensor housing (24), at least one air-supply arrangement (32) for generating an air flow (L) flowing through the sensor accommodation space (26) in the at least one sensor housing (24).

An agricultural equipment air screen cleaning assembly having a frame having an airflow opening having a non-circular outer perimeter, a screen mounted to the frame within the airflow opening and extending to the non-circular outer perimeter, a motor, and a suction wand operatively connected to the motor and located on an upstream side of the screen. The suction wand is rotatably connected about a rotation axis at a central region of the screen, and includes: at least one distal end that is movable in a radial direction with respect to the rotation axis to follow the non-circular outer perimeter as the suction wand rotates about the rotation axis, one or more inlet openings facing the screen, and an internal suction flow path in fluid connection with the one or more inlet openings, the suction flow path extending from a manifold to the distal end of the suction wand.

A method for the evaluation of signals of a rangefinder having at least one sensor point involves carrying out measurements cyclically, wherein the rangefinder emits a plurality of measurement points that indicate a distance from the sensor point. The rangefinder measures distances in a plurality of directions, and a horizontal angle is associated with each measurement point. The measurement points are differentiated into useful signals and interfering signals based on the distance. Measurement points with a distance below a first limiting value are identified as interfering signals, and measurement points above the first limiting value are identified as useful signals. Useful signals are associated with a first measurement area when they satisfy a predetermined condition for distance and horizontal angle. The quantity of useful signals in the first measurement area is determined, and a warning signal is emitted when the quantity of useful signals lies below a first threshold value.

A cooler box for an agricultural harvester includes: a frame including an opening; a screen held in the opening and including a plurality of screen apertures defining a screen aperture size; a cooling fan configured to produce an airstream that flows through a front of the screen; a wand assembly including a wand associated with the screen and a blower coupled to the wand, the wand assembly being configured to vacuum accumulated debris from the screen; and a debris guard covering the front of the screen and including a plurality of guard openings defining a guard opening size that is greater than the screen aperture size.

A harvesting combine has a forward power processing unit (PPU) powered by an internal combustion engine, a rear grain cart for storage of harvested grain, a forward operator cab, a cleaning fan assembly located about the forward bottom of the PPU, and rotor and concaves assembly for threshing grain. The harvesting combine is improved by locating a charge fan assembly behind the forward operator cab and drawing air from about the top of the PPU and directing a portion of an air flow from the charge fan assembly downwardly into the cleaning fan assembly.

A multi-layer segmentation/stalk cutter device for a first season of double-crop rice and a control method, and a combine harvester for a first season of double-crop rice, the multi-layer segmentation/stalk cutter device comprising: a cutting platform, a segmenting cutter and a stalk cutter, at least one segmenting cutter being disposed at a lower rear portion of the cutting platform, the segmenting cutter being hinged on a moving chassis, and a second execution mechanism controlling the cutting height of the segmenting cutter; the stalk cutter being disposed at a lower rear portion of the segmenting cutter, the stalk cutter being hinged on the moving chassis, and a third execution mechanism controlling the cutting height of the stalk cutter.

A system for adjusting the flow orientation of an air flow exhausted at a flow exit location defined along an exterior of an agricultural harvester. The harvester includes an engine upstream of the flow exit location. The system includes a harvester body extending around at least a portion of the exterior of the harvester and defining an opening at the flow exit location; a louvered panel positioned within the opening, the louvered panel including a plurality of louvers each pivotable about a respective pivot axis; and an actuator coupled to the louvers and configured to actuate the louvers such that each louver pivots to adjust a tilt angle of the louver. The air flow is directed through the louvered panel after flowing past the engine and is exhausted from the harvester at a flow angle corresponding to the tilt angle of each of the plurality of louvers.
