A mounting component for securing a crop handling element to a separator rotor is embodied as a profile-section component, with side walls facing toward one another and extending in some portions in the circumferential direction of the separator rotor; for securing the mounting component to the surface of the separator rotor, and each of the side walls of the mounting component has a longitudinal weld seam, extending essentially parallel to the side wall, with a weld seam portion extending beyond the length of the respective side wall, which weld seam portion is embodied at an angle to the respective side wall.

Mounting component for securing a crop handling element to a separator rotor

A device for changing throughgoing openings through which grain passes in a separating area of a concave in an agricultural harvester in which the concave is composed of at least one frame, and a plurality of beater strips and wires which form therebetween the throughgoing openings the concave separating area, the device comprising an adjusting device composed of a plurality of individual tines which are in operative connection with one another through at least one tine strip, a switching shaft, and at least one cam arranged on the switching shaft and controlling the tine strip, wherein the adjusting device is being configured so as to change a size of the throughgoing openings so as to determine a comminution degree of a product mat between a threshing drum and the concave.

Device for changing throughgoing openings in separation area of a concave of a harvester

A method for changing throughgoing openings on separation area of a concave in an agricultural harvester in which the concave is composed of at least one frame, a plurality of beater strips and wires together forming the concave separating area, arranging at least one adjusting device under the concave separating area, and adjusting a width of the throughgoing openings by the at least one adjusting device; and a device for performing the method is provided.

Method of changing throughgoing openings in separation of a concave of a harvester

An agricultural harvesting machine for removing and separating grain from harvested crop has a threshing zone and at least one separation zone for separating the grain. The axial separating rotor is at least partially encased by a separating housing having a plurality of sections. At least one of the sections is displaceable in the axial direction of the at least one axial separating rotor to increase the opening and ensure separation when a correspondingly large proportion of grain are in the outer region of the rotating crop stream and the proportion of admixtures is small.

Adjustable apparatus for separating grain from harvested crop

A self-propelled harvester having a drivable separating rotor rotatably mounted in a rotor housing with a bearing in an end wall covering an inlet opening of the rotor housing at a front end of the separating rotor, further comprising a lower edge transverse and operatively connected to the bearing of the end wall.

Working devices contained in a rotor housing of an agricultural harvester

A self-propelled combine harvester having a threshing device, main threshing drum and feed drum for transferring crop to an axial dividing device. The axial dividing device has two housings that are asymmetrical and expand vertically and horizontally at their inlet ends to ensure uniform and trouble-free transfer of the harvested crop to the dividing device.

Self-propelled combine harvester having asymmetric transaction housings

An apparatus for separating grain, kernel or cereal from harvested crop includes a separating rotor operatively mounted in a rotor housing and having a rotor axis, and a separating grate which partly surrounds the separating rotor and forms a lower part of the rotor housing. The separating grate includes a plurality of frame portions, profiles operatively connected to the plurality of frame portions and extending parallel to the rotor axis, and webs having apertures therein and bent in a step-like shape. The webs are mounted between the profiles and the plurality of frame portions and transverse to the rotor axis forming a sieve area for separating the grain from the crop mat. The separating grate is utilized in a combine harvester, preferably a self-propelled combine harvester. The sieve area is used to sift, separate or loosen grain, kernel or cereal from the crop with reduced fragmentation and clogging.

Grain separating apparatus including step-like webs

A self-propelled combine harvester includes a transfer zone with side panels and a meshing and feed drum which functions on the tangential flow principle. The feed drum feeds the harvested crop to the separating rotors, which function on the axial flow principle and are rotatably mounted in rotor housings. Side panels are operatively mounted on the rotor housing in the frontal pickup region thereof Guide rails are directed upwardly at an acute angle and become increasingly elevated in the direction of conveyance, for imparting an upward, axially directed pulse to the harvested crop whereby the increasing elevation amplifies this pulse without thereby blocking the pickup zone in a frontal region. Dividing wedge for dividing the harvested crop into two paths, wherein the harvested crop glides over the dividing wedge towards the rotor housings and the long stemmed materials, such as stalks, are caught by the separating rotors and drawn into the corresponding rotor housing via the dividing wedge.
