The present application refers to a device designed to thresh agricultural products. The agricultural products it is designed to process include grains in general, particularly peanuts and beans, but not limited thereto, and can be applied to other similar crops. The device includes a cylinder (1) that has a larger diameter zone (2) and smaller diameter zone (3), the larger or smaller diameter zones intermediated by a transition zone (4); in the smaller diameter zone (3) the helical path is contoured by rigid scale-like components (6) as far as part of the transition zone (4), where flexible elements are applied (7) following the entire length of the larger diameter zone (2), completing the (1) cylinder or rotor, and the flexible elements (7) can be arranged in consecutive way or interspersed, so that the interval between the flexible elements (7) is intermediated by substantially upside-down U-shaped elements (7B).

The present invention provides an improved dust control system for removing debris and particulate matter from a fouled air stream. The system may be incorporated into crop harvesting equipment to eliminate the dust pollution generated by conventional harvesting equipment. The dust control system may use a multi-stage air filtering process that employs inertial separation techniques to eliminate particulate matter from the fouled air, without the need for water or electrostatic mechanisms to capture the fine particulates in the fouled air.

A separator module for an agricultural machine. The separator module includes a feederhouse configured to receive crop from a harvesting platform, a casing enclosing a rotor positioned therein and rotatable relative to the casing for processing crop from the feederhouse, a cover extending between the feederhouse and the casing, and a noise control treatment coupled to the cover.

A sieve for a harvester, wherein the sieve has a plurality of louvers and a plurality of cross members adjacent to each one of the plurality of louvers. Wherein, each of the cross members have a fluid channel that directs a fluid through the plurality of louvers.

A combine harvester is disclosed with an infeed arrangement for receiving the harvested material, with a threshing device for degraining the harvested material, and with a cleaning device that is downstream from the threshing device for segregating the harvested material, and thereby separating the grain from the non-grain components. The cleaning device has a sieve device that can rotate about a rotational axis with an at least sectionally sieve-shaped sieve jacket that extends in a peripheral direction around the rotational axis. Separating the grain from the non-grain components is performed by the cleaning device by superimposing a rotary movement and oscillating movement of the sieve jacket such that the oscillating movement is directed transverse to the rotational axis of the sieve device, wherein the oscillating movement is caused by a segmentation of the sieve jacket in a peripheral direction, and a swinging of each peripheral segment of the sieve jacket about a pivot axis associated with the respective peripheral segment.

A sieve assembly for use within an agricultural harvester may generally include a sieve, a crop material sheet, and at least one support element. The sieve extends along a length defined between a first sieve end and a second sieve end and processes a flow of harvested crop material. The sieve also defines a plurality of openings through which cleaned crop material of the flow of crop material is directed. The crop material sheet extends along a length defined between a first sheet end and a second sheet end and receives the cleaned crop material directed through the sieve's openings. The crop material sheet then directs the flow of cleaned crop material towards a separate component of the crop processing system. In addition, the support element(s) is directly coupled between the sieve and the crop material sheet and structurally connects the sieve to the crop material sheet.

A method and device for harvesting grain crops is provided. A threshing method includes separating grain from harvested material, which is fed to a threshing phase after a gathering process taking place against a direction of working travel. During threshing, the harvested material is processed as the respective grain crops and admixtures in the form of straw and chaff such that essential, dischargeable admixtures are separated from the grain crops, and these, in the form of a mixture with chaff or similar fine particles, are fed as a grain/chaff stream to a final cleaning. The grains free of these residual admixtures are subsequently collected as grain crops. During at least one feed phase preceding the final cleaning, a transport movement is imparted to the at least one grain/chaff stream with the transport movement having a component in a vertical direction and a component in the direction of working travel.

The present invention relates to an apparatus and method for seed ablation. In accordance with the method of seed ablation, the apparatus is adapted to expose a heat source to a plurality of seeds while the seeds are in motion. Exposing of the heat source to the moving seed allows ablation of the seeds for de-awning and removing of the appendages of the seeds. In a particular arrangement the seeds are exposed to rotational movement within a centrifugal drum to form a rotating stream of seeds. A torch which reaches into the drum provides a flame directed to the stream of seeds for exposing the seeds to the flame. This allows the ablation of the seed awns and appendages over time as seeds enter into contact with the flame.
