Abstract

The end (25) of the boom (12) on the side of the connector block (18) is mounted on a swivel member (17) with a horizontal axis (20) which can be swivelled simultaneously with the perpendicular swivel axis (19) on the connector block (18) laterally relative to the latter. The horizontal axis can be locked in each of several swivel positions whilst the alignment of the control curve for the rake arms (6) and rake wheel axis (2) in each of the swivel positions advantageously takes place with an adjustment device (9) always in the work direction of the machine. The boom comprises two parts (13) which are guided on or in each other and with their overall length, the rake path and swathe path in each swivel position of the boom can be adapted to the relevant working mode during swathing. The perpendicular swivel axis (19) of the swivel member bearing (28) and the horizontal axis (20) of the boom bearing (21) are set at a slight distance from each other compared to the overall length of the boom.

A haystack

The invention relates to a haystack with the features of the introductory part of claim 1.

For a long time there is a need for a haystack that cannot be mounted on the back or forehead of the tractor, but can act guided along the side of the tractor, and then alternately to the right and left of the tractor, away from the tractor, or to delay the order of the hay. it is necessary to haul the mowing ground over and to double the row of hay at low feed density, thereby substantially narrowing the collector line, as described and shown in DEAS 1 941 095. However, the grab described in this document however has the disadvantage , that no adjustment is provided for changing the height of the rake machine with respect to the tractor or for the lateral swinging movement of the rake machine transversely with respect to the working direction, and there is no possibility of adjusting the rake path and the row arrangement according to the tractor.

DE G 93 15 879 shows such a rake machine which can only be operated sideways on one side of the tractor and for which the height adjustment is provided for the movement of the rake machine as described above, and which together with the front rake machine can cover a large lateral row of hay.

Finally, this machine can also operate behind the tractor in a generally conventional arrangement as a rear-mounted machine.

In the described arrangement, it is not sufficient for the rake wheel mounted on the pier to be used in only one lateral position relative to the tractor, thereby preventing the preferred operating mode as described in the aforementioned document and further that the front horizontal pivot axis for the height adjustment between the machine and the tractor is only allowed to compensate for a limited or simultaneous change of the machine position. In addition, the rear axle work machine is not completely locked when the rear tractor is mounted, as only its rear swing axle is switched off.

It is an object of the invention to improve the rake machine of the foregoing type so that it is usable for work on both sides of the tractor, offsetting of occurring and ground-induced movements with respect to the tractor can follow better, adaptability to different, required rake and row formation is improved and the guidance of the machine when mounted on the rear when operating behind the tractor can follow the rigid setting.

This task is solved in the case of grab machines according to the introductory part of claim 1, using the properties of the characteristic part of claim 1.

A combination of the characteristics described in claim 1 creates a versatile rake machine that completely accomplishes the task at hand. The alignment of the horizontal axis for articulating the pier to the vertical swivel axis of the side frame for the side swivel of the pier creates an even alignment for the height differences between the haystack and the tug, while the flexibility of the trajectory and the row of the machine in relation to the tug is very precise and fast. The half-way and longitudinal adjustability of the pier, and the alignment of the steering and support wheels of the machine, can be controlled by the gear unit via the axis of the rake wheel, depending on the working direction, in particular the tractor. Together with the transverse movement of the machine transversely to the working direction, this creates a machine that is adaptable to one or more working modes.

The sub-claims, which together with claim 1, simultaneously form part of the description, relate to particularly preferred embodiments of the invention.

Using the features of claim 2, the swivel movement of the rake machine is as wide as possible from the grabber wheel, which perfectly follows the straightening movement over a wide swivel range.

The feature of claim 3 is particularly easy to compensate for movement at both ends of the two-piece pier.

With the lateral displacement of the vertical axis for the longitudinal center plane of the attachment frame, the gearshift length of the grab wheel should be kept, the offset of which must be maintained with respect to both sides of the tractor, with the tractor being kept as small as possible in the intended operating modes.

Remotely controlling the lateral relocation of the pier from one working position to another, in particular, simplifies operation when making changes.

Improving steering gives lifting of the rake wheel by the pier to the transport position of the machine as required in claim 6, while, when operating at the rear of the tugboat machine, the actuation of the stop enables the quick and easy positioning of the appropriate position of the attachment frame, pier and the rake wheel. .

The very precise guidance of the two pier piers against each other, as given in claim 7, in particular improves the operation of the rake machine.

The use of the adjusting roller according to claim 8 enables precise and quick adjustment of the new position of the rake wheel with respect to the tractor following the turn at the end of the circle.

The articulated attachment of the pier directly to the rake wheel via the rigidly fixed bracket given in claims 9 and 10 eliminates the uncontrolled movements of the machine, while the flaps of the rake wheel depending on the working direction can freely occur between the stops.

By articulating the pier in front of the plane of the axis of the rake wheel, the rake wheel with its own weight is held in the end position, thus preventing the grabbing tines from gripping the ground due to the impact. For the operation of the rake wheel when mounting on the rear of the tractor, it is preferable to switch off the rotation by installing the rotary axes, just as in the transport of the rake wheel raised behind the tractor.

The invention is described by way of a sketch of an embodiment, where FIG. 1 is a schematic layout of the rake machine with the inclusion of a tractor and a front rake machine in the top view;

FIG. 2 is a schematic view of the machine of FIG. 1 in the straight position of the rake wheel behind the tractor, partly cut off, the pier in the extended position and further illustrated in the retracted position, in the side view.

The hay rake comprises a rake wheel 1 driven rotatably mounted on the upright axis 2 of the rake wheel, which (axis 2 namely) rests on the ground with a pair of support wheels 3, 3 'mounted on a carrier 5 of the support wheels, which (carrier) 5 namely) height-adjustable articulated to the axle 2 rigidly connected console 4 support wheels.

On the rake wheel 1 there are rotatably mounted rake arms 6 which, controlled by the steering curve, periodically bring the rake wheels 7 to the ground into the rake position when rotating the rake wheel 1, and then eject them again.

The housing of the rake wheel 8, in which the rake wheel is mounted, carries a gear 9 with which a steering curve rigidly connected to the axis 2 and which directs the supporting wheels 3, 3 'to each pivot position 27, 27', 27 ”occupied by the rake wheel 1 in the working direction 10 of the rake wheel 1, so that the rake area and the row deposition area remain substantially constantly maintained with respect to the working direction 10, without deviations from 10 to 20 angular degrees having no effect.

The housing 8 is provided with a hinge bracket 11, which is rigidly attached to the housing and on which the end 26 of the pier 12 is arranged pivotally arranged around the horizontal by the rake wheel, with respect to its longitudinal course of the perpendicular pivot axis 15 of the hinge bracket 16. The other end 25 of the pier 12, arranged by the attachment frame, is articulated with the attachment frame 18 for attachment to the three-point device 39 of the tractor 30.

The horizontal swinging axis 15 of the hinge bracket 16 rests in front of the plane 36 through the axis 2 of the rake wheel and transversely with respect to the working direction 10, so that the inherent weight of the rake wheel forms a uniquely rotary position of the machine, which prevents the grabbing rails 7 from being hit by the impact. performed on the machine.

The width of the swivel of the pier 12 is limited by the upper and lower flaps 37, 38, between which the rake wheel 1 can perform swivel movements transversely with respect to the working direction 10.

For the operation of the rake wheel 1 behind the tractor, the lower stop 38 on the articulated bracket lis can be fixed to the rig 24 against the pier 12 and rigidly fixed.

The pier 12 is two-part and consists of a partial pier 14 arranged on the side of the attachment frame, on which a pier 13 is arranged in the guide 29 with a roller bearing guided by the rake wheel.

A hydraulic adjusting roller 32 is arranged between the two piers 13 and 14 to adjust the entire length of the pier 12 and thereby the position of the rake path and the area of disposal of the row of the rake wheel 1 with respect to the tractor 30.

At the end 25, arranged on the side of the attachment frame, there is a pier 12, and thus a partial pier 14 is arranged on the side of the attachment frame, pivotally pivotally mounted on the pivot piece 17 via the horizontal, with respect to the longitudinal course of the pier 12 of the rectangular axis 20 of the bearing 21 of the pier. .

The swivel piece 17, which, by comparison with the entire length of the pier 12, itself has a small length, is laterally pivotally mounted on the attachment frame 18 about the vertical swivel axis 19 of the bearing 28 of the swivel piece. The rotation is followed by a hydraulic adjusting roller 31 from the tractor 30.

Between the pivot piece 17 and the pier 12, a height latch 23 of the pier is mounted, which is connected to a hydraulic adjusting roller 33, which restricts the piercing of the pier 12 upward into the transport position of the rake machine to pass over the ground-lying beehive, which is accomplished by acting on a backrest device. 34, by inserting a flap.

As the pier 12 is further rotated to the higher transport position of the rake wheel 1, the stop 34 is first switched off and the hydraulic adjusting roller 33 is brought clean to the stop.

b

For locking the flap 17 in the intended flap positions 27, 27 ', 27 "of the pier 12, in which the rake wheel 1 is arranged laterally with respect to the tractor 30 or behind it when reversing, there is provided a locking device 22 of the flap with a properly positioned latch position , which is operated from the tractor.

For the transport position of the rake wheel 1 and, if desired, also for the work behind the tractor, the rake wheel 1 is changed to the minimum length of the pier by the assembly of partial piers 13 and 14. The horizontal rotary axes 15 and 20 are then locked rigidly with the height lock 23 of the pier and fixed. preparation 24.
