"Distributor spraying device suspended from a vehicle"

The invention relates to a distribution or spraying device suspended from a vehicle according to the preamble of Claim 1. Such spray devices are also called distribution or spray bars or also wide spray frames. They will; in the tractor angnhön ^ t iibnr ilia I alder driven and are equipped with a liquid line, which is provided in a association of at a distance from each other Spray nozzle ends. The liquid is supplied to the nozzles via the line from a container carried along.

A pump is usually provided to achieve the necessary spray pressure.

Such distribution or spraying devices have a relatively large one that extends transversely to the direction of travel Span so that you can work on the largest possible area per trip. They consist of several members, which have to be folded up for normal road transport.

BAD OSlGiNAL

In addition, distribution or spraying devices are known to have a correspondingly large span (e.g. IQ, 12 or 15 m) different systems of a pendulum suspension on the tractor, in order to drive and spray in the field to always achieve a parallel position of the distribution or spraying device to the ground.

The invention is concerned with the problem, during the driving and spraying operations in the field only with a part, e.g. B. optionally one (left) or the other (right) side of the distribution or spraying device, to be able to fold in, while with the non-folded part can be further distributed or sprayed. This is repeatedly necessary in practice, e.g. B. If there are high-voltage pylons or other obstacles in a field, or if there are trees, hekens and similar obstacles at the edge of the field. Then she has to There is a possibility, consciously only with a lower part, z. B. half the span of the Vertuil or Cspray device to work. In such a case, however, a

2ü one-sided load on the Schlcappurs with the distribution or door Spray device take place, provided that the otherwise existing weight compensation by folding in a part, e.g. one side of the distribution or spraying device is no longer given. The invention aims to solve this problem to solve.

With the invention, based on the preamble of claim 1, the combination of features is therefore initially in accordance with the characterizing part of claim 1 provided. While in the prior art explained at the beginning, only the left and the right urIte through Vortuilodor spray device could be folded together, here is a sub-area, in particular each page individually

(ο

foldable so that you can z. B. only with half the working width of the distribution or spraying device over the field can drive. The resulting imbalance, which occurs in the pendulum suspension according to the generic term of claim 1 would lead to the lowering of the non-locked side of the distributing or spraying device, is canceled or blocked by the locking device, so that the desired flawless driving and spraying or Distribution operation with e.g. half the working width is possible in every possible spray height position of the spray frame to the ground. This height of the spray position depends on the culture to be sprayed. You can e.g. vary between 50 and 180 cm. Reference is made to the preferred embodiment according to claim 4 in this regard.

On the other hand, it is used with the normal working width, i.e. without asymmetrical folding in of parts of the distribution or Sprinkler driven in the field, the locking device is made ineffective and it occurs the desired Pendulum a.

With the features of claim 2, first, if necessary, in the case of a locking or blocking of the oscillating suspension according to the characterizing part of claim 1 Compensation of bearing tolerances take place. Such bearing tolerances can be due to the one-sided loading at the center asymmetrical folding in of parts (links) of the distribution or spraying device an unintentional lowering of the not so much retracted, i.e. longer half when spraying by an amount that is not great, but noticeable have as a consequence. Furthermore, the features of the claim can also be used to create a sloping position dos vehicles (tractor) to balance to the earth's surface. Such inclinations can arise especially when the vehicle has the wheels on one side in a furrow or outside the field drives on a lower (or higher) field edge and the like.

BATH ORIGINAL

A preferred embodiment of the invention is content of claim 4. This oscillating suspension is the content of DE-GM 84 14 363 of the present applicant. the The toggle lever arrangement provided there can be blocked in a simple manner. For this purpose, for example the further preferred embodiment according to claim referenced.

The features of claim 6 also include a preferred embodiment for the invention Setting of the pivot position of the distribution or spraying device to the vehicle, so that the vehicle can be tilted to the ground and / or to be able to compensate for the bearing tolerances mentioned.

Further advantages and features of the invention can be found in the following description and the associated drawing of possible embodiments of the invention. It shows:

In FIGS. 1 to 6, these are Γ nhr / .HU; ¹ ;, ikis ['nruli;lr;y;; camouflage and the associated locking or advance devices are essentially not shown. Only FIG. 1 shows the toggle lever arrangement 15, 16, to be explained in more detail below with reference to FIGS. 7, 8, which is articulated at 13 on the spray frame of the distribution or spraying device and at 12 on the vehicle. 14 is the point of articulation between the two toggle levers 15, 16. The one pendulum position on the right in the drawing is indicated by 16 '. A corresponding oscillation to the other, left side is ubmvfall ;; possible (not shown).

The spray frame here consists of five sections or sections 1 to 5, with section 3 being the middle piece and Forms the basic basis. The aforementioned members are connected to one another via the hinges 8, 6, 7 and 9 can be folded down in the directions of the arrows 10, the start of such a position being indicated by dashed lines on the left in FIG Folding between the links 1 and 2 is shown.

BAD DSIGSNAL

It can be seen that the links of one half, i.e. 1 and 2 on the one hand, or the links of the other half, i.e. 4 and 5, on the other hand, can each be folded up to the area of the middle link 3 (see Figs. 3 and 4) Thus, with the remaining non-folded members (in Figs. 3 and 4, the members' 4 and 5) the means be sprayed or distributed. But you can also proceed in such a way that with the one preferred and shown here Embodiment, namely division into a middle and two times two side links only the outermost of the side links can be folded in (not shown). So you can e.g. only link 1 Rügen link 2 fold or but only link 5 against link 4 or at the same time link 1 against link 2 and link 5 against link 4. Closing the combinations are still possible that link 1 and 2 are folded and only link 5j or also link 5 and 4 and link 1 are collapsed. Spraying or spreading takes place only through the unfolded ones Links, because as soon as one of the side links 1, 2, 4 or 5 are folded in, this folding process the supply of the medium to be sprayed or distributed by means or devices not shown in detail interrupted. This allows the operator, depending on the location of the field driven by him Machining paths when obstacles such as HochüpaiTniingamoütun, li.'jumen, Str'iuntinr etc. dtui jnwailii'.on Requirements for the width of the spray frame and also to the position of such a broad scope in relation adapt to the vehicle. The folding and unfolding of the links can be done hydraulically, which is annoying for the driver and time-consuming double dismounting and mounting again is saved, which is the case with the prior art for folding the Frame parts by hand was necessary.

The pendulum-like suspension, already briefly indicated with reference to FIG. 1, is closer to the grüßorun Maßytüb 7 to 9 can be seen. The vehicle 23 with wheels 24 is only indicated by dash-dotted lines, which are on the Drive ground 25. Fig. 9 shows how the hinge point 13 between the frame 18 and the lower toggle lever is slidably mounted in a vertical link 26 of the tractor 23. This pendulum suspension has the advantage that when driving the tractor over [Jaden-HD bumps occurring bumps or fluctuations has been transferred to the spray frame. This would have; namely due to the large opening width of the syringe frame, undesirable fluctuations result. The horizontal Axis 18 'of the spray frame 18 must always be on the right to the vertical axis 27 of the tractor Level the angle, both on level and on sloping terrain. In other words: this pendulum system is designed in such a way that the spray frame level automatically follows the tractor level by the spray frame does not remain in the position by gravity, but is always adapted to the terrain via the tractor will. So that both sides have ip; nn Auslegc-cmm; of Splash frame always cinn the same Aliüti-inrt vum I rdhoden.

The above-mentioned pendulum system can, however, be used in the event of i.e. if one of the cases of the above-mentioned possibilities of folding the limbs occurs, where one side is overweight, can be locked. So the one-sided protruding, overweight Part of the boom of the spray frame is still in the correct position for spraying or spreading. Such Locking can take place by means of a slide, a sleeve or the like 21, which is moved from the position according to FIG

BAD OFIIGiNAL

Fig. 7 is moved to the position of Fig. 8 (22). In Fig. 7 it is only in the area of the upper one Toggle lever 16, so that the pendulum device is functional. In the position of FIG. 8, it is both in the area of the upper and lower toggle levers 16 and 15 and blocks both toggle levers against one Buckling around the hinge point 14. This locking of the pendulum fan suspension is in every spray hood position of the spray frame possible.

With the help of an adjustable length, z. B. hydraulic Uliodus 17, the angular position between the spray frame 18 and the pendulum device (here the lower lever 15) changed in both directions be, d. H. both in the position indicated by 19 and in the position indicated by 20. This is used for the explained Compensation of bearing tolerances and / or inclinations of the tractor to the ground. In this position, if necessary, also the locking of the pendulum device take place, as can be done with part 21, for example. This has a corresponding change the angular positions of the spray frame to the vertical tractor axis result.
