A coupling sleeve (1) for a hydraulic coupling has a member to receive and arrest a coupling plug. To open the plug valve of the coupling plug, a switching pin (16) is provided which passes through the valve body (9) of the coupling sleeve (1). In the open position, the pin (16) projects beyond the end face (12) into the receiving means (6). If the switching member (30) is opened by mistake, and it is to be returned to its closed position, the switching pin (16) must move into the starting position against the pressure in the sleeve chamber (37). To accomplish this movement, the switching pin (16) has an opening valve. The opening valve has an opening valve body (21) arranged in a through-channel (17) in the switching pin (16). The through-channel effects a connection between the receiving means (6) and the sleeve chamber (37) when the switching member (30) is returned into a closed position. Thus, the switching member (30) is able to return against the pressure building up in the sleeve chamber (37).

Hydraulic sleeve for hydraulic coupling

A coupling for connecting hydraulic pipelines has a first coupling part (1) and a second coupling part (2). The two coupling parts each include a valve (V1, V2, V3). A receiving part (4) is provided which is associated with the first coupling part (1). The receiving part (4) serves to receive the second coupling part (2). A locking sleeve (38) and a locking element (40) can be locked relative to the receiving part (4). To facilitate actuation of the locking sleeve (38) in the opening sense, a rotational play is provided between a switching member (23) to actuate the valve body (8) of the valve (V1) and the switching shaft (27) to actuate the switching member (23). The rotational play can be used for moving the locking sleeve (38) into the open position via an opening element (47) which is adjusted by an actuating element (48).

Hydraulic coupling

A sieve for separating grain crops from a chaff-straw mixture, used in agricultural harvesting machines, particularly harvester threshers and which is passed from below by a blower wind current includes alternating elongated grooves and channels aligned in parallel relative to the crop conveying direction. The grooves and channels are alternately open on the top or on the bottom, respectively, and have lateral legs with openings, through which the crop can pass from the grooves open on the top to the channels open on the bottom.

Sieve for harvesting machines

A cleaning sieve assembly disposed at the end of and below a transporting conveyor of the harvested crop in the harvesting machine includes an upper or shaff sieve and a lower sieve both subjected to an air current blown from a blower. The upper sieve includes a plurality of inclined sieve zones, which may be descending or ascending in respect to the plane of the sieve with the inclination which is adjustable.

A control for a structural assembly oscillatingly supported around a swivel axis on a base unit in a harvesting machine and including a cutter table inclinably supported about an axis of rotation relative to a conveyor channel, has an hydraulic operation cylinder. The inclination of the cutter table relative to the conveyor channel is effected by the hydraulic operation cylinder pivoted at one end to the conveyor channel and at the other to the cutter table. An hydraulically loaded relief cylinder, the pressure medium of which is cushioned by a pressure reservoir, is installed with one end to the conveyor channel and with the other end to the cutter table so as to balance a position of the cutter table relative to its point of rotation by the force of the relief cylinder.

A control device for controlling a cutter table oscillatingly supported on a base unit about an axis of rotation of a harvesting machine, wherein the cutter table is inclinable about the longitudinal axis of a harvester thresher, the inclination being effected by a hydraulically operating cylinder relative to a conveyor channel. The operating cylinder is pivoted at one end to the conveyor channel and, at the other end, to the cutter table. A spring bridges the hydraulically operating cylinder and rests on one end at the operating cylinder and, on the other end, at a piston rod of the operating cylinder and is biased by a bolt nut on a threaded portion of the piston rod so that an imbalance of the cutter table relative to its point of rotation is equalized.

A distributing and smoothing tool has a grip (2) releasably connected to a trowel blade (1). A fastening rail (10) has a top hat shape, in cross section, with outwardly bent flanges (14,15) which rest on the upper face (16) of the trowel blade (1). The flanges (14, 15) are connected to the upper face (16) by rows of spot welds (17,18), one row along each flange. The grip (2) is supported by a grip base (5), which is appropriately formed in a U-shape in cross section, and positioned on the fastening rail (10). The end faces (26,27) of the limbs (6,7) of the grip base (5) are supported on the faces of the flanges (14,15) away from the trowel blade 1. An attachment (19) of the fastening rail (10), engages into a recess (20) of the grip base (5), and a knurled screw (23) engages into a threaded borehole (21) of the fastening rail (10) and secures to the grip base (5).

The invention concerns a new arrangement of the reaping platform of harvesting machines with a feed drum (2) supported behind the cutter bar (3) in the direction of travel and with, where appropriate, a reel (5) interacting with it, the bearing arrangement of the feed drum (2) being adjustable forwards and backwards in the horizontal direction relative to the cutter bar (3) and, if appropriate, being adjustable so that it can move up and down in the vertical direction relative to the bottom of the reaping platform trough (1).

Reaping platform for harvesting machines

The invention relates to a cutter blade for mowers of harvesting machines the cutter bevel of which comprises two zones of different inclination relative to the blade leaf plane wherein between the zone molded to the cutting edge and the zone extending to the upper blade plane a gradation is provided. It relates furtheron to a method for the production of said cutter bevels on cutting blades of mowers which comprise two zones having different blade angles relative to the blade leaf plane wherein in a first embossing process the zone of the cutter bevel extending to the upper blade plane is pressed into the blade blank in parallel to the cutting edge provided and in a subsequent embossing process, the zone extending to the cutting edge is molded on and the embosssing portion extending beyond the lower blade leaf plane is ground away.

A mowing finger for finger bar mowers of harvesting machines having first and second opposing finger parts each formed of flat material. The first and second finger parts are fixedly secured to each other to define a gap therebetween for mowing action between them. The mowing finger has a tapered front portion located forward of the blade gap and a rear portion secured to a finger bar. One of the first or second finger parts includes a twisted portion twisted around the longitudinal axis of the mowing finger and fixedly secured to the other end of the finger parts to provide increased rigidity to the mowing finger. At least one vegetation-excluding deformation is formed in the first or the second finger parts in the area of the blade gap and extends into the blade gap to narrow and obstruct the blade gap against the accumulation of plant matter therein.
