Abstract: An attachment for connection to a harvester comprises a plurality of picking devices (2) arranged next to each other and in a distributed manner along the working width. Each picking device (2) has a picking gap (6), below which are disposed at least two picking rotors (10) which can be driven to rotate in opposite directions, the picking rotors (10) being provided with flutes (12), which project in a radial direction beyond the rotor casing (16) and the enveloping circles (20) of which mesh with each other. To propose a way of easily adapting the picking rotors to different harvesting conditions without having to replace them all, the invention proposes for one or more shear bars (18) which are releasably connected to the picking rotor (10) and/or to the flutes (12) to be inserted in the intermediate space (22) between adjacent flutes (12) of a picking rotor (10), the shear bars filling portions of said intermediate space during a rotating movement of the picking rotors (10).

Abstract: The invention relates to a cutting mechanism (4) for installing on a harvesting machine (2). The aim of the invention is to provide a cutting mechanism which comprises a mounting for the cutting elements and which adapts easily to the soil contour without thereby tilting into an uncontrolled swing. This is achieved in that multiple or all of the rocker arms (16) are designed as a respective leaf spring assembly (20) composed of multiple leaf springs (22), multiple or all of the leaf springs (22) lying flatly one on top of the other as a leaf spring assembly (20) are held together on the frame (6) between clamping elements (24) at the frame-side leaf spring ends, and only one or multiple leaf springs (22) arranged in the upper region of the leaf spring assembly (20) are connected to the cutting elements (18).

Abstract: The present invention relates to a device (2) for harvesting stalk-like stem crops, having a number of picking units (4) which are arranged alongside one another on the frame (6) of the device (2) and each have picking plates (12), laterally delimiting a picking gap (14), and picking rotors (16) located therebeneath, conveying units which are assigned to the respective picking units (4), are configured as continuous conveyors (22) that are driven in circulation, are arranged on opposite sides above a picking gap (14) and are configured with drivers (18) fastened to the circulating elements, and a transverse conveying device (8) arranged downstream of the conveying units.

Abstract: The invention relates to a device (2) for harvesting stalk material, comprising a feed region, a conveyor device (4), a picking device, and a device which is arranged on a plane below the picking device for cutting stalks and has at least one cutter that rotates in a circulating manner on a horizontal or at least approximately horizontal plane. The aim of the invention is to provide a device with which the vegetable structure of the stubble pieces are damaged in addition to being cut such that bacteria and moisture can more easily penetrate the interior of a stalk piece, in particular stubble standing on the field. This is achieved in that at least one impact element (22) is formed on the cutter (18) which rotates in a circulating manner, said impact element rising over the thickness of the cutter blade.

Abstract: An attachment device for harvesting stalky stem material is provided with stem dividers; cutting devices cutting the stalky stem material; conveying devices conveying the cut stalky stem material; picking units distributed across a working width of the attachment device and provided with picking rollers and picking gaps to separate fruit from the stalks; milling devices associated with the picking units; and a device collecting and combining the fruit separated from the stalks. Drivable stalk supports are arranged in a travel direction of the attachment device upstream of the picking units and positioned vertically spaced relative to the picking units and to the cutting devices. Pivotable support arms support the stalk supports. The stalk supports are moved by the support arms in a longitudinal direction, with respect to the vertical position, and with respect to an attack angle, and are adjusted with respect to their rotary speed.

Abstract: A corn head attachment has a sweeper device extending across a working width of the corn head attachment. The sweeper device is attached to the attachment frame by support arms pivotable about a first pivot. The sweeper device position relative to the frame is adjustable by a longitudinal adjusting device parallel to the travel direction and height-adjustable about the first pivots. The adjusting device moves the sweeper device along a curved path in a first direction away from a first position, in which a rotary axle of the sweeper device is at a leading area of a harvesting slot, into a second position above a rearward area of the harvesting slot and also moves the sweeper device in opposite direction. The adjustment of the sweeper device along the curved path is controlled by a forced guiding action to avoid collision of the sweeper device with other corn head attachment components.
