The harvesting device for harvesting corn or other grains is embodied as an attachment for a combine and provided with a draw-in device (3) and one picking gap for separating the cobs from the plants (stalks). Furthermore, the harvesting device has one driven picking roller (4) with beater plates per row, as well as a cheek-like guide plate associated with this picking roller (4) and partially enshrouding it, or alternatively, a bracing support extending paraxially to the picking roller and embodied as a driven counter-roller (5). A connection piece (20) acting as a separating and comminuting cutter and stabilizing the distance between the picking roller (4) and the bracing support (5) is disposed in the plant intake (PE) between the picking roller (4) and bracing support (5). This connection piece (20) extends crosswise, preferably at right angles to the plant intake (A) and thus to the longitudinal axis of the picking roller (4) and is formed by a sheet metal plate with an upper cutter edge (21) extending at least almost vertically in respect to the longitudinal axis of the picking roller.

Device for harvesting corn or other grains

A harvesting implement for harvesting of corn and other grain products, to be arranged in front of a harvester thresher, comprises a driven drawing roller having a substantially cylindrical main body and a plurality of impact plates provided with cutouts, a cutting block provided with cutting elements extending through the cutouts, and a counter holder associated with the drawing roller. The counter holder is formed as a driven counter roller which is axes parallel to the picking roller, the counter roller includes a main body with a plurality of segments spaced from one another, the drawing roller and the counter roller are both associated with the one common cutting block, the cutting elements of the cutting block include a plurality of cutters which extend simultaneously in the intermediate spaces between the segments of the counter roller and in the cutouts of the impact plates of the drawing roller.

Harvesting aggregate

An agricultural implement for harvesting corn or other grain fruits to be used especially as a front implement as a harvester thresher comprises a drawing unit, a unit forming a picking gap for separating cobs from a fruit, a picking roller surrounded by a partial casing and having a cylindrical base body with a plurality of impact plates provided with cutouts, a cutting unit provided with a plurality of cutting members extending through the cutouts, the cutting unit having an end which is opposite to the cutting members, a joint traverse supporting the cutting unit at the end independently of the partial casing the turnable about an axis extending parallel to an axis of the picking roller, the traverse together with the cutting unit being turnable against a spring force about an axis which extends parallel of the axis of the base body and being arrestable upon turning.

Agricultural implement for harvesting of corn and other grain fruits

A positional regulation of a mowing mechanism is effected in terms of height as a function of a ground pressure signal (SB) and in terms of swiveling in the transverse direction as a function of lateral ground clearance signals (SL, SR), the adjusting signals being carried to hydraulic valves (VT, VH; VL, VR). The goal is to increase the accuracy and freedom from fluctuation in the course of the mowing mechanism cutting height. The ground clearance signals (SL, SR) are used in proportion with the ground pressure signal (SB) for vertical position regulation. A linkage of these signals (SL, SR, SB) with further transducer signals and a method for automatic adaptation of the regulating characteristic by varying the hystereses and idle times of the regulators (V1, V1) is disclosed. The regulating apparatus is used in harvesting and threshing combines when low-height crops are to be mowed and when the ground is bumpy and soft.

Apparatus and method for changing the position of a mowing mechanism

A self-propelling harvester thresher comprises a conveyor, a two-part cutting mechanism having two cutting mechanism halves which are turnable substantially in a horizontal plane between a working position and a transporting position, elements allowing the turning of the cutting mechanism halves and including two turnable supports and a joint vertically extending hinge axle. The cutting mechanism halves are each connected through a respective one of the turnable supports with the inclined conveyor and also are connected with one another by the hinge axle.

Self-propelling harvester thresher with two-part cutting mechanism

A liftable and lowerable product receiving arrangement for agricultural machines, especially for self-propelling harvester threshers, comprises a cutting mechanism platform having a front end, a flexible cutting bar mounted on the front end of the cutting mechanism platform, sliding skids arranged to support the cutting bar in a height-displaceable manner relative to the cutting mechanism platform, and supporting skids associated with the cutting mechanism platform and arranged behind the flexible cutting bar as considered in a transporting direction and at least in its both lateral end regions, the supporting skids have lower limits extending at most at a height of one of the cutter bar and the sliding skids.
