Abstract

A pick-up attachment for a harvesting machine includes a pick-up rotor having pick-up tools for picking crop up from the ground. The pick-up rotor is connected to at least one guide element on the ground that guides the pick-up rotor to the ground. The pick-up rotor along with the at least one guide element is suspended on the machine frame of the pick-up attachment by control arms, so as to swing. Each control arm is connected to the pick-up rotor with one end, in an articulated manner, and to the machine frame with the other end, in an articulated manner, so that during push travel of the pick-up attachment, a push point forming the attack point of a thrust direction vector defined by the control arms is arranged below the contact point that forms between the ground and the guide element, when the pick-up rotor assumes a certain position.

Abstract

A harvesting device includes a conveying member having controlled tines. In order to protect the controlled tines and the crankshaft on which the controlled tines are mounted from an overload. The overload protection is connected on its side facing the dead shaft to the dead shaft and on its side facing away from the dead shaft, via a retainer, to the frame; the overload protection operates as a spring element, which, under the action of an overload, through spring motion, allows a rotary motion of the dead shaft from an initial position into a deflected position by absorbing an overload acting on the dead shaft and, building up in itself restoring forces, and, after the disappearance of the overload, the spring element can move back automatically into its original position, driven by restoring forces in the spring element, and also resets the dead shaft to its initial position.

Abstract

The invention relates to a folding pick-up attachment (10) for a harvesting machine, preferably for a forage harvester, wherein the pick-up attachment has a receiving rotor (12) and a feed screw, that is subdivided into two feed screw parts (16a, 16b). The feed screw is mounted on the machine frame (18) in a pendular manner, so that the feed screw can be adjusted to different layer thicknesses of the harvested crop. Since, in the transport position, the foldable machine frame part (18a) is transferred vertically through 180° over the unfolded machine frame (18b), it is necessary to reversibly fix the pendular-mounted feed screw part (16a) with respect to the machine frame part, in order to prevent pivoting during the transfer from the working position into the transport position. A corresponding device (20) is provided for this purpose, which ensures that the feed screw is fixed.

A header for a harvester has a reel extending transverse to a working direction of the header. The reel has reel rake tubes distributed circumferentially about the reel. Reel tines are fastened to the reel rake tubes. At least some reel tines are rotatably supported in bearings at the reel rake tubes and can rotate about a rotation axis along a movement path, predetermined by a control, from a neutral position into an evasion position and back. The evasion position corresponds to a spatial position in which a free end of the reel tines has moved in a direction corresponding to a conveying direction of the conveying device in the region of the reel tines. A distance of the free end to the reel rake tube in evasion position is reduced in relation to a distance of the free end to the reel rake tube in neutral position.

The invention relates to an attachment device for assembling on a harvesting machine, comprising a number of picking devices which are arranged adjacently to one another in a distributed manner over the working width. Each of the picking devices has a picking gap, in which two picking rotors (2) are arranged that can be rotated in opposite directions. Each of the picking rotors (2) is provided with multiple drawing edges (6) which protrude in the radial direction and are formed on drawing elements (4) and the enveloping circles (16) of which mesh into one another, and adjacent drawing elements (4) of a picking rotor (2) delimit intermediate spaces (10) positioned within the enveloping circle (16) between one another, wherein the intermediate spaces extend along the longitudinal direction of the picking rotor (2), and the drawing edges (6) of the opposing picking rotor (2) dip into the intermediate spaces during a revolution of the picking rotors (2). The aim of the invention is to improve the flow of crops in the region of the picking rotors. This is achieved in that the trailing drawing elements (4) of both picking rotors (2), said elements delimiting an intermediate space (10), have a cross-sectional shape, in which the free ends facing outwards are curved in a leading manner in the rotational direction, on the side facing the respective intermediate space (10).

An eccentric shaft supported in the gear housing carries a gear wheel arranged in a second plane above or below the first plane. The drive shaft drives the gear wheel through a bevel gear. First and second eccentric discs, arranged in third and fourth planes, respectively, are connected to the eccentric shaft; first and second eccentric levers are correlated therewith. First and second pivot levers are connected to the first and second eccentric levers and connected to stationarily supported pivot shafts. Crank arms connected to the pivot shafts, respectively, transmit their pivot movement to the cutter bar parts.

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 agricultural cutting device has knife bar sections with section knife blades. A drive with phase offset drives the knife bar sections at least temporarily in opposite directions. The section knife blades interact scissor-like with counter knives. The knife bar sections have adjacently positioned bar ends. When the knife bar sections move, a gap of varying size is formed between the bar ends. A mowing finger is arranged at the gap. A stationary knife blade with first cutting edges is arranged at the mowing finger. The first cutting edges are arranged adjacent to the mowing finger and extend at a slant relative to a forward travel direction of the cutting device so that the cutting edges have a V-shaped arrangement broadening in travel direction. The knife bar sections have an outer knife blade attached to the bar ends whose cutting edges extend parallel to the travel direction.
