A harvester may include a crop path along which crops are moved, a working member to interact with weed seeds moving along the crop path and a controller. The controller is to receive data indicating forthcoming weed seeds and is to output control signals controlling the working member based on the data.

Disclosed is a grain separating apparatus (1) for a combine harvester (2). The grain separating apparatus (1) comprises at least a first walker-sieve (3) and a second walker-sieve (4) arranged side by side, wherein the first walker-sieve (3) and the second walker-sieve (4) are suspended in at least two suspension points (5,6) in the combine harvester (2) and wherein at least one of the two suspension points (5,6) is arranged to describe a rotational motion. A rotational motion drive (7) is arranged to drive the rotational motion of the first walker-sieve (3) out of phase with the rotational motion of the second walker-sieve (4), wherein each of the at least two walker-sieves (3,4) include a straw walker (8) comprising drivers (9) for conveying a straw material (10) and wherein grain (11) and debris (12) are separated from the straw material (10) through walker apertures (13) arranged in the straw walker (8). Furthermore, the straw walker (8) is arranged on top of at least one sieve (14,15) which is arranged to separate grain (11) from the debris (12) and wherein the straw walker (8) and the at least one sieve (14,15) are rigidly connected. Furthermore, a method for separating grain (11) from straw material (10) in a combine harvester (2) by means of a grain separating apparatus (1) as described above.

The present invention provides a peeling, screening and cleaning device for Torreya grandis Merrilliis. The device comprises an outer rectangular water container, the inner surface of the outer rectangular water container is fixedly connected with the first antirust horizontal separating net, the inner surface of the outer rectangular water container is fixedly connected with the second antirust horizontal separating net. According to the device, the outer pericarp can be separated from the Torreya grandis Merrilliis through the cooperation of the outer rectangular water container, water pump and hard water spray pipe.

A monitoring system for a combine harvester. The monitoring system includes a sensor configured to provide a measurement wave to a flow of crop residue on the harvester and to receive a response wave from the flow of crop residue. The monitoring system further includes a processor having an input terminal for receiving a response signal of the sensor representative of the response wave. The processor is configured to determine a crop parameter associated with the density of the flow of crop based on the response signal of the sensor. The processor further has an output terminal for outputting a density signal representing the crop parameter.

An agricultural vehicle including at least one threshing rotor and an auger bed located underneath the at least one threshing rotor. The auger bed has a working position and a cleaning position. The auger bed includes a frame, a plurality of augers rotatably coupled to and supported by the frame, and a trough portion moveably connected to the frame. In the working position the bottom surface of the trough portion is positioned underneath the plurality of augers and in the cleaning position the entire trough portion is moved relative to the frame so that the bottom surface of the trough portion is not positioned underneath at least a portion of the plurality of augers, creating an open space underneath the portion of the plurality of augers for allowing an unwanted material to pass therethrough.

An operator interface for a combine harvester, having a display device, input means and a processor configured to activate the display device such that the display device depicts having an elongated element, a scale being assigned thereto, and a first marking, the position thereof relative to the elongated element depending on an operating parameter of the threshing device and/or the cleaning device. A second marking and/or third marking, which represents a lower and/or upper limit of the setting range of the operating parameter which is predetermined depending on the type of crop, is assigned to the elongated element in the diagram.

A fan hub for an extractor for a harvesting machine that harvests a crop. The fan hub having a hub cover positioned along a rotation axis of a fan of the extractor. The hub cover is adjustable to alter the profile of the hub cover relative to the rotation axis.

A combine including a chassis, a crop residue handling system including a residue chopper, residue spreader, a spreader chute and a swath selection door, a receiver configured to determine a location of the combine, and a controller that controls the residue handling system. The controller configured to determine the location of the combine on a map, execute a crop residue spreading mode in response to the controller determining that the location of the combine is located in a designated crop residue spreading zone indicated on the map, and execute a crop residue windrow mode in response to the controller determining that the location of the combine is located in a designated crop residue windrow zone indicated on the map.

A tumble trimmer system having a tumbler barrel with a perforated axle adapted for introducing a freezing agent such as liquid carbon dioxide or other liquefied gas adapted to flash freeze the plant material when infused into the mesh tumbler barrel, the mesh tumbler barrel adapted with mesh netting or screening for trimming and/or separating plant material enclosed therein, and with an open funnel or chute positioned below the tumbler barrel adapted to catch and direct trimmed and/or separated plant material exiting the tumbler barrel into a bin or container positioned under the funnel or chute, wherein the perforated axle comprises a plurality of perforations positioned around a circumference of and along an entire length of the axle.
