Abstract
A self-propelled harvester with a harvest distributor is disclosed. A self-propelled harvester, in particular for green fodder, has a cutting device (2) for cutting the harvest, a conveyor (4) for conveying the harvest, a processing device (5.1, 5.2) for processing the harvest, a pressing device (7) for pressing the harvest into mats and a depositing device (8) for depositing the mats on the fields. In order to ensure a trouble-free passage of the harvest through the individual devices of the harvester, and to improve or increase its capacity in comparison with known state-of-the-art harvesters, the pressing device is directly arranged behind the processing device, dispensing with a dosing device.
Description
~ ~ n ~ ~ 7 9 ~O 96/08133 PCT/EP95/03457 Self-propelled harves~er Description The invention concerns a self-propelled harvester, in particular for crop harvesting including green fodder, according to the description of claim 1.
Such a self-propelled harvester is, for example, known from the European Patent Application 0 408 850 Al. In the case of the harvester described and shown in this document, the harvested crop is cut by a mower, treated by a processing device, collected in a buffer space and moved on, metered by a feed-regulating roller, to a pressing device where, from the processed harvested crop by means of the pressing device, a mat is pressed which at the end of the harvester is put down on the field. Such a harvester realized in practice has indeed proven itself, however, it has turned out that the construction cost for the buffer space with the feed-regulating roller is high and that, due to the metering, the throughput capacity was limited.
A process and a device to process harvested crops is ~nown through EP-A 0 543 312. This is a harvester which picks up cut and swathed together straws or leafy material, delivers it to a processing device and passes this on afterwards to a pressing device which is designed wider than the processing device. A
distribution arrangement is provided between the processing device and the pressing device. The distribution arrangement consists of rotary tines, spreader rollers, tine conveyers, distribution screws or driven distribution tines. Common to all these distribution elements though is that they carry out the distribution by actively influencing the harvested crop. Since power is required to drive these distribution elements, this distribution arrangement is not optimally designed from the point of view of energy.
Amended page ~0~7 9 .O 96/08133 PCT/EP95/03~57 - la -The object of the invention is therefore to design a self-propelled harvester in such a way that the passage of the harvested crop takes place as trouble-free as possible through the individual devices of the harvester and that, moreover, the throughput capacity is improved and increased respectively compared to the hitherto known harvester.
- Amended page ~n~7 9 WO 96/08133 PCT/EP95/03~57 This problem is solved by means of the features of the distinguishing part of claim 1.
According to the invention, it is provided that the pressing device is arranged directly behind the processing device, omitting a feed-regulating device, so that the harvested crop, after leaving the processing device, is fed directly to the pressing device without substantial intermediate storage. By the fact that, compared to the prior art, the feed-regulating device is omitted, blockages which are caused by the feed-regulating device in that the excess harvested crop that cannot be processed by the pressing device is thrown back gain, are effectively avoided. For this purpose, the pressing device is spatially arranged directly behind the processing device in which case, between the processing device and the pressing device, an intermediate space can still be provided which serves as temporary storage in which case, however, this temporary storage is clearly smaller than the storage space known from the prior art. Through the direct arrangement of the two devices behind one another, the throughput of harvested crop is effectively increased.
In a further development of the invention, the processing device has a smaller width than the pressing device and, in addition, a distribution arrangement is arranged between the processing device and the pressing device in which case the distribution arrangement is placed in such a way in the flow of harvested crop and influences the latter in such a way that the harvested crop, coming from the processing device, is distributed onto a width corresponding to the greatest extent possible to the width of the ' ~2~Q7~
WO 96/08133 PCT/~P~5/03~57 pressing device. In the construction of the self-propelled harvester, it proved to be practical to arrange the processing device in an area below the driver's cabin where the driver' cabin is above a front wheel unit (see also Fig. 1). Because of this design fact, the processing device is arranged approximately between the driven wheels of the front wheel unit so that due to the inside sides of the front wheels and also due to the laterally situated drive of the processing device, the width of the processing device is limited Since the pressing device essentially is arranged in an area above a rear wheel unit, of which the wheels are steerable, the width of the pressing device, compared to the width of the processing device, can clearly be greater. In addition to this, it is therefore provided according to the invention that between the processing device and the pressing device, the distribution arrangement is located which distributes the processed harvested crop coming from the processing device on a width corresponding to the greatest extent possible to the width of the pressing device in order to thus utilize as much as possible the entire width of the pressing device so that the highest possible efficiency of the pressing device is achieved with the highest possible efficiency of the processing device.
In a further development of the invention, the distribution arrangement is designed as a screw in which case the pitch of the spiral when viewed in the longitudinal direction of the screw increases from the center to the two outer ends of the screw.
Thus, a first embodiment is provided for the distribution arrangement which operates effectively and is of a simple design.
The spiral can be continuous or discontinuous where, in the case of the discontinuous type, at least part of the spiral segments, WO 96/08133 PCT/EP95~03457 however, advantageously all spiral segments can be adjusted.
Alternatively to the screw, it is also conceivable to use a roller with tines arranged on the surface where the tines are arranged similarly to the spiral or uniformly on the surface. It is here also conceivable to arrange part of the tines fixed (for example, the center tines) and another part of the tines adjustably, or to adjust all tines.
In a further development of the invention, the distribution arrangement has a tine roller with a guiding device arranged behind it, in which case this is another embodiment of the distribution arrangement. Such a designed distribution arrangement has moreover the advantage that the tine roller can be manufactured simply and inexpensively, in which case the proposed guiding device (as is still to be described in -the Figures) is a standard component from the harvester-thresher field so that here full use can be made of cost effective savings.
In a further development of the invention, the distribution arrangement can at least be partly, in particular completely, swung out of the flow of harvested crop. In addition to this, it is provided that the distribution arrangement can, as a function of the volume of harvested crop, be swung out of the flow of harvested crop, in particular swung out automatically. This has the advantage that, depending on the volumes of harvested crop that is cut, fed to the processing device and delivered by the processing device, the harvested crop is, or is not, distributed over the entire width of the pressing device. If only a small volume of harvested crop is obtained because, for example, the crop on the field is poor, or the harvester turns at the edge of the field, the distribution arrangement is swung advantayeously partly, or in particular completely, out of the flow of harvested crop so that the processed harvested crop, coming from the processing device, is processed on a width of the pressing device which corresponds to the width of the processing device. Thus, a mat is produced by the pressing device which has approximately the width of the processing device. If a larger volume is obtained, the distribution arrangement is again swung into the flow of harvested crop so that by the pressing device, a mat is produced which now essentially corresponds to the width of the pressing device. To swing the distribution arrangement as a function of the volume of harvested crop, a sensor can be provided which registers, for example, the volume of the cut, or also the volume of processed, harvested crop and triggers an actuator (for example, a hydraulic cylinder) which swings the distribution arrangement.
In a further development of the invention, a conveyer belt is arranged, at least in the area between the end of the processing device and the start of the pressing device, which transports the harvested crop from the processing device towards the pressing device and thus helps the flow of the harvested crop to increase the throughput.
Over and above that, the conveyer belt presents a spatial limita-tion in which case the conveyer belt is arranged below the distribution arrangement.
In a further development of the invention, a device is provided in the area of the conveying installation to adjust, in particular to reduce, the width of a conveying area of the 7 ~
W0 96/08133 PCT/~P95/03457 conveying device. This has the advantage that in the case of small quantities of harvested crop, the flow of harvested crop can be reduced in its width already in the area before the processing device in order to transport this with a smaller width (smaller than the width of the processing device) through the processing and the pressing device so that the reliable and optimum processing and pressing is ensured also for small quantities of harvested crop (harvesting short crops).
Conceivable here are, for example, slides in front of the inlet of the conveyer or the processing device, or even tiltable or slidable baffles in the area of the conveyer device, with which the width of the flow of harvested crop can be adjusted, in particular can be reduced, starting with the width of the conveying device or the processing device. If a reduction of the width takes place, it has to be ensured that the narrow flow of harvested crop is not widened by the distribution arrangement.
In a further development of the invention, the guiding device, having the cross-pieces arranged on the distribution plate, can be put into an oscillating movement. This can take place in particular if the distribution device is designed as distribution plate with thereupon arranged cross-pieces. Such an oscillating movement has the advantage that thereby a further distribution and equalization of the flow of harvested crop is obtained, which consists of processed harvested crop, and is fed to the pressing device. Due to the equalization, an effective increase of the throughput of harvested crop is provided. In addition, it is thereby achieved that the processed harvested crop is fed more uniformly to the pressing device whereby a uniform formation of the mat is obtained, in particular with regard to the width and the thickness of the mat. In this embodiment, it is provided 7 ~
WO 96/08133 P~Ti~P95~03~57 that the cross-pieces, which are arranged on the distribution plate and are arranged either stationary or at least partly rotatable on the distribution plate, are put into the oscillating movement together with the distribution plate.
In a further development of the invention, at least part of the cross-pieces can be put into an oscillating movement whereby the effect described above is achieved in which case, however, tlle distribution plate is arranged fixed or rotatably fixed (to swing out of the flow of harvested crop). Thus, an alternative embodi-ment to achieve the oscillating movement is provided.
In addition to the mentioned embodiments of the guiding device, it is further provided that, seen in the direction of the flow of harvested crop, behind the distribution arrangement, in particular behind the guiding device, another device is arranged to influence the flow of harvested crop. The arrangement of such an additional device has for one thing the advantage, in case the distribution arrangement is provided as distribution plate with thereupon arranged fixed cross-pieces, that a more uniform distribution of the processed harvested crop, which is fed to the pressing device, is obtained. Moreover, through the additional device the effect is achieved that in particular with large quantities of harvested crop, the distribution, which is carried out by the distribution arrangement, is improved by the additional device so that also in this way an increase in the throughput is provided. This additional device can, for example, again be embodied as screw, as tine roller or vertically rotating tines (as, for example, is known from the rotary hayers) A self-propelled harvester as well as a concrete exemplified 7 ~
embodiment for the distribution arrangement is described in tl~e following and shown in the figures.
Here Fiq. 1 shows a self-propelled harvester,~iq. 2 shows a distribution arrangement embodied according to the invention, Fiq. 3 shows embodiments of a guiding device, Fiq. 4 shows embodiments of a variable guiding device,~iq. 5 shows another distribution arrangement embodied according to the invention.
Fig. 1 shows a self-propelled harvester 1, in particular for green fodder, which has a cutting device 2 (represented schematically) to cut the crop, a processing device which consists of a central roller 5.1 as well as several planetary rollers 5.2, in which case the rollers have different peripheral speeds and are driven in opposing directions to process the harvested crop and a conveyer belt 6 which adjoins the processing device and to (sic) a pressing device which consists of at least two press rollers 7 forming a gap to press the harvested crop to a mat and a device 8 to deposit the mat onto the field. The cutting device 2 is advantageously a rotary grass cutter, which is installed in a trough in addition to a feed screw 3, in which case the trough advantageously is a component from the harvester-thresher field. This trough can be attached to a not shown feed channel in which a conveying device 4 is integrated in which case the conveying device 4 advantageously is a chain conveyer, also from the harvester-thresher field, which transports the harvested crop cut by the cutting device 2 in the direction of tlle Q ~ ~
WO 96/08133 P~T/EP95/03457 processing device. The removability of the trough at the start of the feed channel has the advantage that in addition to the rotary grass cutter, other mowers can also be attached, in whic case the selection of the to-be-attached mower is a function of the crop.
As shown in Fig. 1, the distribution arrangement is located between the processing device (central roller 5.1 and planetary rollers 5.2, the use of a processor according to the tandem roller technique is also conceivable) and the pressing device (press roller 7), in which case the processing device and the pressing device are arranged directly behind one another, in which case this distribution arrangement is designed as a schematically represented distribution screw 9 where the arrow, as also for the other rollers, indicates the direction of rotation of the distribution screw 9.
The harvester 1 has moreover a driver's cabin 10, wheel units 11 and an internal combustion engine 12 as well as a fuel tan]~ 13.
The drive of the harvester 1 itself as well as the operation of the individual devices of the harvester 1, possibly through the intermediary of couplings and gears, takes place from the internal combustion engine 12. The processing device shown in Fig. 1 is, for improved representation, shown raised in the area between the driver's cabin 10 and the front wheel unit 11 in which case, however, in practice the processing device is "deeper" so that the width of the central roller 5.1 and the planetary rollers 5.2 is restricted due to the inwards directed sides of the tires of the wheel unit 11 and the lateral drive (belt drive) of the rollers of the processing device. If, as, for example, shown in Fig. 1, there is no such restriction of the WO 96/08133 PCT/EP95/03~57 width, the processing device can be designed wider, in particular in a width which corresponds to the width of the pressing device.
In such a case, it is conceivable to arrange a distribution arrangement (for example, the distribution screw or a distributor device as is described in the following) in the area between the end of the conveying device 4 and the feed area of the processing device so that in this location, the harvested crop is distributed from the width of the conveying device 4 to the greater width of the processing device. The proposed designs of the distributor device can also be used here.
Fig. 2 shows an embodiment of a distribution arrangement in which case the distribution arrangement has a tine roller 20, on the circumferential surface of which tines 21 are arranged which, for example, have a triangular cross-section, with a guiding device 22 arranged behind it. The guiding device 22 consists of a distribution plate 23 on which, vertical to the surface, cross-pieces 24 are arranged. The distribution plate 23 extends at least over the width of the processing device, advantageously, however, over the width of the pressing device and the conveyer belt 6 respectively. The harvested crop delivered by the processing device, which forms at least together with the central roller 5.1 and the planetary rollers 5.2 an independent unit 50 which can be replaced, is pic]~ed up by the tines 21 of the rotating tine roller 20 and slung against the guiding device 22, that is, against the bottom side of the distribution plate 23 on which the cross-pieces 24 are arranged. Here, the rotational speed of the tine roller 20 can be selected in such a way that the velocity of the harvested crop, with which it leaves the processing device, is increased, reduced or kept constant. The arrangement of the cross-pieces 24 is shown in Figs. 3 and 4 ~ ~ O ~ ~ 7 ~
WO 96/08133 PCT/~P95~03~57 respectively.
In order to swing the guiding device 22 at least partly, in particular completely, out of the flow of harvested crop, the guiding device 22 is for one thing supported by a pivo-t 25 on an arm 26 in which case the pivot 25 is in an elevator 27. It is also conceivable to swing the guiding device 22 out of the flow of harvested crop only by the pivot 25 or only by means of the elevator 27. The arrangement shown in Fig. 2 operates as follows: By means of the elevator 27, the guiding device 22 can either be swung completely into the flow of harvested crop or swung out of the latter as the dashed position indicates.
Moreover, intermediate positions of the elevator 27 are conceivable. The adjustment of the elevator 27 takes place manually or automatically, in particular as a function of the picked up volume of harvested crop. In addition to this, the guiding device 22 is mounted spring loaded (not shown) on the pivot 25. By means of this spring tension (compression spring), the guiding device is kept in a specific position in which case, however, in case of an increased volume of harvested crop, the guiding device 22 can at least partly be swung, around -the pivot 25 against the spring tension, out of the flow of harvested crop Furthermore, it is shown in Fig. 2 that also the distribution arrangement forms an independent unit 90 which, for example, can be removed completely for maintenance work. The harvested crop thus coming from the processing device (unit 50) is transported by the tine roller 20 and the adjoining guiding device 22, supporting the direction of movement of the conveyer belt 6, towards the pressing device (indicated by the arrow with the reference number 7 in Fig. 2). In this case, the pressing device can also form an independent and not further described unit which 7 ~
WO 96/08133 PCT/EP95/03~57 likewise can be replaced. Moreover, it is practically feasible that the conveyer belt is either led around two independent rollers (as, for example, is shown in Fig. 1) or that a roller, around which the conveyer belt 6 is led, is at least one of the press rollers 7. At this point, it should be mentioned that the pressing device can also have more than one pair of press rollers 7.
Fig. 3 shows an embodiment of the guiding device 22, in which case in Fig. 3 the bottom side of the distribution plate 23 is shown which points in the direction of the flow of harvested crop. In the left part of Fig. 3 or of the distribution plate 23, the cross-pieces are of a straight design and in the right part of an arch-shaped, curved design. Advantageously, the cross-pieces 24, arranged on the distribution plate 23, are either of only a straight design or only of an arch-shaped, curved design. As is shown in Fig. 3, when viewed in the longitudinal direction of the distribution plate 23, at least one cross-piece 24, located in the center area, is essentially arranged in the longitudinal direction (represented by the dashed line) of the flow of harvested crop in which case the other cross-pieces 24, arranged in the direction towards the two outer areas of the distribution plate 23, deviate in such a way from the longitudinal direction that the harvested crop, coming from the processing device (in which case the width of the processing device is denoted by BA) and the tine roller 20 respectively, is distributed on a width corresponding to the greatest possible extent to the width of the pressing device which is denoted by the reference symbol BP. In addition to the embodiment in Fig.
3, it is conceivable to arrange on the distribution plate 23 more or fewer than the six shown cross-pieces 24, in which case the 7 ~
WO 96/08133 PC~/EP95/03457 height of the cross-pieces 24 can also be varied, and cross-pieces 24 can also be arranged at the outer longitudinal area of the distribution plate 23. It is also c'onceivable to arrange a straight aligned cross-piece exactly on the longitudinal axis.
To support the distribution effect, it is also conceivable -to design at least part of the cross-pieces in the shape of a fan.
Another embodiment of the guiding device 22 is shown in Fig. 4.
In this embodiment, the cross-pieces 24 can be swiveled around a swiveling point 28 in which case the swiveling can be carried out by means of a swivel lever 29 (or by means of two swivel levers 29). The swiveling can, in particular as a function of the picked up volume of harvested crop, be automated hy that at least one hydraulic cylinder 30 engages the swivel lever 29 and the swiveling takes place continuously. In a simple embodiment, the swiveling of the swivel lever 29 can ta]se place manually in which case, for example, the cross-pieces 24, due to a click-stop device, can be set in different discontinuous positions. On the scale to the left, next to the distribution plate 23, the flow of harvested crop is shown which passes in front of the distribution plate 23, in the area of the distribution plate 23 and behind the distribution plate 23 respectively. The harvested crop, which is processed by the processing device (rollers 5.1 and 5.2), is picked up by the tine roller 20 and slung against the guiding device 22 in which case, as a function of the position of the cross-pieces 24, the harvested crop is distributed by the guiding device 22 on a width which essentially is between the width BA
and the width BP whereafter it is then fed to the pressing device (rollers 7). The distribution device can, of course, be constructed in such a way that the harvested crop is distributed by the guiding device 22 onto a width which is smaller than the 7 ~
WO 96/08133 PCT~PS5~03457 width BA, whereafter it is then fed to the pressing device (rollers 7). This has the advantage that also small quantities of harvested crop can be pressed reliably to a mat Also this embodiment is a feature of the invention.
Also the other device to influence the harvested crop, which is located behind the distribution arrangement, can be designed in such a way (for example, in a design as is ]~nown from hay swathers) that the processed harvested crop, coming from ~he processing device and the distribution arrangement respectively, is distributed (brought together) onto a width which is smaller than the width BA whereafter it is then fed to the pressing device. This has in particular then the advantage if the distribution arrangement is designed in such a way that i-t distributes the harvested crop coming from the processing device in fact onto a width BP which is greater than the width BA in which case, however, there would be no reliable formation of mats due to too small quantities of harvested crop. Thus, by means of the additional device, the processed harvested crop can again be brought together so that, on the one hand, the mat can be pressed reliably and, on the other hand, for example, by swinging the additional device in and out, all resulting quantities of processed harvested crop (small as well as large quantities) can be pressed reliably to a mat.
As is shown in Fig. 4, the cross-pieces 24 can be adjusted via the swivel lever 29. Here, to achieve the oscillating movement, it is conceivable that through an appropriate actua-tion of the hydraulic cylinder 30 by a not shown control, this puts the swivel lever 29 and thus the cross-pieces 24 in the oscillating movement, pivot 28 (sic). Alternatively and/or in addition to W0 96/08133 PCT/~P95/03~57 this, it is conceivable, by appropriate mountiny of the distribution plate 23 on a not shown pivot, to put the distribution plate 23 itself in the oscillating movement for which the hydraulic cylinder 30 then engages tlle distribution plate 23. This essentially vertical oscillating movement can be replaced or supplemented by an essentially horizontal oscillating movement which takes place by an appropriate hinging of the distribution plate 23 via the arm 26 and the elevator 27 respectively. It is likewise conceivable that to equalize the flow of harvested crop, the distribution plate 23 is put in the oscillating movement, while the width, on which the processed harvested crop is distributed, is set via the hydraulic cylinder 30 shown in Fig. 4. The oscillating movement of the distributio plate 23 and/or the cross-pieces 24 ta]~es place advantageously, leaving out, for example, the distribution screw 9 shown in Fig.
1 and the tine roller 20 shown in Fig. 2 respectively. But the oscillating movement can also be provided with the mentioned distribution devices.
To clean the tines of the tine roller and the cross-pieces respectively, it is conceivable to draw, for example, at preset time intervals or on putting into operation or after the use of the harvester, a comb-like device across the tines (provided these are arranged in a row in the circumferential direction and are not staggered) and across the cross-pieces respectively and thus to remove any dirt present.
Fig. 5 shows another distribution arrangement embodied accordiny to the invention.
This further embodiment of the guiding device 22 consists in that 7 ~
the distribution plate 23 already shown in Fig. 2 is hrought up into the outlet area of the processing device and has again cross-pieces 24 at its bottom side. In this embodiment, the arrangement of the tine roller 20 is eliminated because the processed harvested crop leaves the processing device at such a speed as a result of which the processed harvested crop is slung against the bottom side of the distribution plate 23, is distrib-uted by the cross-pieces 24 onto a larger (in the case of adjust-able cross-pieces also onto a smaller) width and is afterwards fed to the pressing device. In Fig. 5, it is shown that the distribution plate 23 is again attached to the elevator 27 on the arm 26, in which case this distribution plate 23 can also be arranged stationary in the area above the conveyer belt 6. It is also conceivable to swivel the distribution plate 23 according to Fig. 5 around a longitudinal axis at the end, facing the processing device or the pressing device, so that this distribution plate can be swung into the discharge area of the processing device or swung out of the latter. An arrangemen-t of the cross-pieces 24 on the distribution plate 23 can also here take place according to the arrangements (fixed or adjustable) shown in Figs. 3 and 4.
Such a self-propelled harvester is, for example, known from the European Patent Application 0 408 850 Al. In the case of the harvester described and shown in this document, the harvested crop is cut by a mower, treated by a processing device, collected in a buffer space and moved on, metered by a feed-regulating roller, to a pressing device where, from the processed harvested crop by means of the pressing device, a mat is pressed which at the end of the harvester is put down on the field. Such a harvester realized in practice has indeed proven itself, however, it has turned out that the construction cost for the buffer space with the feed-regulating roller is high and that, due to the metering, the throughput capacity was limited.
A process and a device to process harvested crops is ~nown through EP-A 0 543 312. This is a harvester which picks up cut and swathed together straws or leafy material, delivers it to a processing device and passes this on afterwards to a pressing device which is designed wider than the processing device. A
distribution arrangement is provided between the processing device and the pressing device. The distribution arrangement consists of rotary tines, spreader rollers, tine conveyers, distribution screws or driven distribution tines. Common to all these distribution elements though is that they carry out the distribution by actively influencing the harvested crop. Since power is required to drive these distribution elements, this distribution arrangement is not optimally designed from the point of view of energy.

- Amended page ~n~7 9 WO 96/08133 PCT/EP95/03~57 This problem is solved by means of the features of the distinguishing part of claim 1.
According to the invention, it is provided that the pressing device is arranged directly behind the processing device, omitting a feed-regulating device, so that the harvested crop, after leaving the processing device, is fed directly to the pressing device without substantial intermediate storage. By the fact that, compared to the prior art, the feed-regulating device is omitted, blockages which are caused by the feed-regulating device in that the excess harvested crop that cannot be processed by the pressing device is thrown back gain, are effectively avoided.

WO 96/08133 PCT/~P~5/03~57 pressing device.

In a further development of the invention, the distribution arrangement is designed as a screw in which case the pitch of the spiral when viewed in the longitudinal direction of the screw increases from the center to the two outer ends of the screw.
Thus, a first embodiment is provided for the distribution arrangement which operates effectively and is of a simple design.
The spiral can be continuous or discontinuous where, in the case of the discontinuous type, at least part of the spiral segments, WO 96/08133 PCT/EP95~03457 however, advantageously all spiral segments can be adjusted.
Alternatively to the screw, it is also conceivable to use a roller with tines arranged on the surface where the tines are arranged similarly to the spiral or uniformly on the surface. It is here also conceivable to arrange part of the tines fixed (for example, the center tines) and another part of the tines adjustably, or to adjust all tines.
In a further development of the invention, the distribution arrangement has a tine roller with a guiding device arranged behind it, in which case this is another embodiment of the distribution arrangement. Such a designed distribution arrangement has moreover the advantage that the tine roller can be manufactured simply and inexpensively, in which case the proposed guiding device (as is still to be described in -the Figures) is a standard component from the harvester-thresher field so that here full use can be made of cost effective savings.
In a further development of the invention, the distribution arrangement can at least be partly, in particular completely, swung out of the flow of harvested crop. In addition to this, it is provided that the distribution arrangement can, as a function of the volume of harvested crop, be swung out of the flow of harvested crop, in particular swung out automatically. This has the advantage that, depending on the volumes of harvested crop that is cut, fed to the processing device and delivered by the processing device, the harvested crop is, or is not, distributed over the entire width of the pressing device. If only a small volume of harvested crop is obtained because, for example, the crop on the field is poor, or the harvester turns at the edge of the field, the distribution arrangement is swung advantayeously partly, or in particular completely, out of the flow of harvested crop so that the processed harvested crop, coming from the processing device, is processed on a width of the pressing device which corresponds to the width of the processing device. Thus, a mat is produced by the pressing device which has approximately the width of the processing device. If a larger volume is obtained, the distribution arrangement is again swung into the flow of harvested crop so that by the pressing device, a mat is produced which now essentially corresponds to the width of the pressing device. To swing the distribution arrangement as a function of the volume of harvested crop, a sensor can be provided which registers, for example, the volume of the cut, or also the volume of processed, harvested crop and triggers an actuator (for example, a hydraulic cylinder) which swings the distribution arrangement.
In a further development of the invention, a conveyer belt is arranged, at least in the area between the end of the processing device and the start of the pressing device, which transports the harvested crop from the processing device towards the pressing device and thus helps the flow of the harvested crop to increase the throughput.
Over and above that, the conveyer belt presents a spatial limita-tion in which case the conveyer belt is arranged below the distribution arrangement.
In a further development of the invention, a device is provided in the area of the conveying installation to adjust, in particular to reduce, the width of a conveying area of the 7 ~
W0 96/08133 PCT/~P95/03457 conveying device. This has the advantage that in the case of small quantities of harvested crop, the flow of harvested crop can be reduced in its width already in the area before the processing device in order to transport this with a smaller width (smaller than the width of the processing device) through the processing and the pressing device so that the reliable and optimum processing and pressing is ensured also for small quantities of harvested crop (harvesting short crops).
Conceivable here are, for example, slides in front of the inlet of the conveyer or the processing device, or even tiltable or slidable baffles in the area of the conveyer device, with which the width of the flow of harvested crop can be adjusted, in particular can be reduced, starting with the width of the conveying device or the processing device. If a reduction of the width takes place, it has to be ensured that the narrow flow of harvested crop is not widened by the distribution arrangement.
In a further development of the invention, the guiding device, having the cross-pieces arranged on the distribution plate, can be put into an oscillating movement. This can take place in particular if the distribution device is designed as distribution plate with thereupon arranged cross-pieces. Such an oscillating movement has the advantage that thereby a further distribution and equalization of the flow of harvested crop is obtained, which consists of processed harvested crop, and is fed to the pressing device. Due to the equalization, an effective increase of the throughput of harvested crop is provided. In addition, it is thereby achieved that the processed harvested crop is fed more uniformly to the pressing device whereby a uniform formation of the mat is obtained, in particular with regard to the width and the thickness of the mat. In this embodiment, it is provided 7 ~
WO 96/08133 P~Ti~P95~03~57 that the cross-pieces, which are arranged on the distribution plate and are arranged either stationary or at least partly rotatable on the distribution plate, are put into the oscillating movement together with the distribution plate.
In a further development of the invention, at least part of the cross-pieces can be put into an oscillating movement whereby the effect described above is achieved in which case, however, tlle distribution plate is arranged fixed or rotatably fixed (to swing out of the flow of harvested crop). Thus, an alternative embodi-ment to achieve the oscillating movement is provided.
In addition to the mentioned embodiments of the guiding device, it is further provided that, seen in the direction of the flow of harvested crop, behind the distribution arrangement, in particular behind the guiding device, another device is arranged to influence the flow of harvested crop. The arrangement of such an additional device has for one thing the advantage, in case the distribution arrangement is provided as distribution plate with thereupon arranged fixed cross-pieces, that a more uniform distribution of the processed harvested crop, which is fed to the pressing device, is obtained. Moreover, through the additional device the effect is achieved that in particular with large quantities of harvested crop, the distribution, which is carried out by the distribution arrangement, is improved by the additional device so that also in this way an increase in the throughput is provided. This additional device can, for example, again be embodied as screw, as tine roller or vertically rotating tines (as, for example, is known from the rotary hayers) A self-propelled harvester as well as a concrete exemplified 7 ~
embodiment for the distribution arrangement is described in tl~e following and shown in the figures.
Here Fiq. 1 shows a self-propelled harvester,~iq. 2 shows a distribution arrangement embodied according to the invention, Fiq. 3 shows embodiments of a guiding device, Fiq. 4 shows embodiments of a variable guiding device,~iq. 5 shows another distribution arrangement embodied according to the invention.
Fig. 1 shows a self-propelled harvester 1, in particular for green fodder, which has a cutting device 2 (represented schematically) to cut the crop, a processing device which consists of a central roller 5.1 as well as several planetary rollers 5.2, in which case the rollers have different peripheral speeds and are driven in opposing directions to process the harvested crop and a conveyer belt 6 which adjoins the processing device and to (sic) a pressing device which consists of at least two press rollers 7 forming a gap to press the harvested crop to a mat and a device 8 to deposit the mat onto the field. The cutting device 2 is advantageously a rotary grass cutter, which is installed in a trough in addition to a feed screw 3, in which case the trough advantageously is a component from the harvester-thresher field. This trough can be attached to a not shown feed channel in which a conveying device 4 is integrated in which case the conveying device 4 advantageously is a chain conveyer, also from the harvester-thresher field, which transports the harvested crop cut by the cutting device 2 in the direction of tlle Q ~ ~
WO 96/08133 P~T/EP95/03457 processing device. The removability of the trough at the start of the feed channel has the advantage that in addition to the rotary grass cutter, other mowers can also be attached, in whic case the selection of the to-be-attached mower is a function of the crop.
As shown in Fig. 1, the distribution arrangement is located between the processing device (central roller 5.1 and planetary rollers 5.2, the use of a processor according to the tandem roller technique is also conceivable) and the pressing device (press roller 7), in which case the processing device and the pressing device are arranged directly behind one another, in which case this distribution arrangement is designed as a schematically represented distribution screw 9 where the arrow, as also for the other rollers, indicates the direction of rotation of the distribution screw 9.
The harvester 1 has moreover a driver's cabin 10, wheel units 11 and an internal combustion engine 12 as well as a fuel tan]~ 13.
The drive of the harvester 1 itself as well as the operation of the individual devices of the harvester 1, possibly through the intermediary of couplings and gears, takes place from the internal combustion engine 12. The processing device shown in Fig. 1 is, for improved representation, shown raised in the area between the driver's cabin 10 and the front wheel unit 11 in which case, however, in practice the processing device is "deeper" so that the width of the central roller 5.1 and the planetary rollers 5.2 is restricted due to the inwards directed sides of the tires of the wheel unit 11 and the lateral drive (belt drive) of the rollers of the processing device. If, as, for example, shown in Fig. 1, there is no such restriction of the WO 96/08133 PCT/EP95/03~57 width, the processing device can be designed wider, in particular in a width which corresponds to the width of the pressing device.
In such a case, it is conceivable to arrange a distribution arrangement (for example, the distribution screw or a distributor device as is described in the following) in the area between the end of the conveying device 4 and the feed area of the processing device so that in this location, the harvested crop is distributed from the width of the conveying device 4 to the greater width of the processing device. The proposed designs of the distributor device can also be used here.
Fig. 2 shows an embodiment of a distribution arrangement in which case the distribution arrangement has a tine roller 20, on the circumferential surface of which tines 21 are arranged which, for example, have a triangular cross-section, with a guiding device 22 arranged behind it. The guiding device 22 consists of a distribution plate 23 on which, vertical to the surface, cross-pieces 24 are arranged. The distribution plate 23 extends at least over the width of the processing device, advantageously, however, over the width of the pressing device and the conveyer belt 6 respectively. The harvested crop delivered by the processing device, which forms at least together with the central roller 5.1 and the planetary rollers 5.2 an independent unit 50 which can be replaced, is pic]~ed up by the tines 21 of the rotating tine roller 20 and slung against the guiding device 22, that is, against the bottom side of the distribution plate 23 on which the cross-pieces 24 are arranged. Here, the rotational speed of the tine roller 20 can be selected in such a way that the velocity of the harvested crop, with which it leaves the processing device, is increased, reduced or kept constant. The arrangement of the cross-pieces 24 is shown in Figs. 3 and 4 ~ ~ O ~ ~ 7 ~
WO 96/08133 PCT/~P95~03~57 respectively.
In order to swing the guiding device 22 at least partly, in particular completely, out of the flow of harvested crop, the guiding device 22 is for one thing supported by a pivo-t 25 on an arm 26 in which case the pivot 25 is in an elevator 27. It is also conceivable to swing the guiding device 22 out of the flow of harvested crop only by the pivot 25 or only by means of the elevator 27. The arrangement shown in Fig. 2 operates as follows: By means of the elevator 27, the guiding device 22 can either be swung completely into the flow of harvested crop or swung out of the latter as the dashed position indicates.
Moreover, intermediate positions of the elevator 27 are conceivable. The adjustment of the elevator 27 takes place manually or automatically, in particular as a function of the picked up volume of harvested crop. In addition to this, the guiding device 22 is mounted spring loaded (not shown) on the pivot 25. By means of this spring tension (compression spring), the guiding device is kept in a specific position in which case, however, in case of an increased volume of harvested crop, the guiding device 22 can at least partly be swung, around -the pivot 25 against the spring tension, out of the flow of harvested crop Furthermore, it is shown in Fig. 2 that also the distribution arrangement forms an independent unit 90 which, for example, can be removed completely for maintenance work. The harvested crop thus coming from the processing device (unit 50) is transported by the tine roller 20 and the adjoining guiding device 22, supporting the direction of movement of the conveyer belt 6, towards the pressing device (indicated by the arrow with the reference number 7 in Fig. 2). In this case, the pressing device can also form an independent and not further described unit which 7 ~
WO 96/08133 PCT/EP95/03~57 likewise can be replaced. Moreover, it is practically feasible that the conveyer belt is either led around two independent rollers (as, for example, is shown in Fig. 1) or that a roller, around which the conveyer belt 6 is led, is at least one of the press rollers 7. At this point, it should be mentioned that the pressing device can also have more than one pair of press rollers 7.
Fig. 3 shows an embodiment of the guiding device 22, in which case in Fig. 3 the bottom side of the distribution plate 23 is shown which points in the direction of the flow of harvested crop. In the left part of Fig. 3 or of the distribution plate 23, the cross-pieces are of a straight design and in the right part of an arch-shaped, curved design. Advantageously, the cross-pieces 24, arranged on the distribution plate 23, are either of only a straight design or only of an arch-shaped, curved design. As is shown in Fig. 3, when viewed in the longitudinal direction of the distribution plate 23, at least one cross-piece 24, located in the center area, is essentially arranged in the longitudinal direction (represented by the dashed line) of the flow of harvested crop in which case the other cross-pieces 24, arranged in the direction towards the two outer areas of the distribution plate 23, deviate in such a way from the longitudinal direction that the harvested crop, coming from the processing device (in which case the width of the processing device is denoted by BA) and the tine roller 20 respectively, is distributed on a width corresponding to the greatest possible extent to the width of the pressing device which is denoted by the reference symbol BP. In addition to the embodiment in Fig.
3, it is conceivable to arrange on the distribution plate 23 more or fewer than the six shown cross-pieces 24, in which case the 7 ~
WO 96/08133 PC~/EP95/03457 height of the cross-pieces 24 can also be varied, and cross-pieces 24 can also be arranged at the outer longitudinal area of the distribution plate 23. It is also c'onceivable to arrange a straight aligned cross-piece exactly on the longitudinal axis.
To support the distribution effect, it is also conceivable -to design at least part of the cross-pieces in the shape of a fan.
Another embodiment of the guiding device 22 is shown in Fig. 4.
In this embodiment, the cross-pieces 24 can be swiveled around a swiveling point 28 in which case the swiveling can be carried out by means of a swivel lever 29 (or by means of two swivel levers 29). The swiveling can, in particular as a function of the picked up volume of harvested crop, be automated hy that at least one hydraulic cylinder 30 engages the swivel lever 29 and the swiveling takes place continuously. In a simple embodiment, the swiveling of the swivel lever 29 can ta]se place manually in which case, for example, the cross-pieces 24, due to a click-stop device, can be set in different discontinuous positions. On the scale to the left, next to the distribution plate 23, the flow of harvested crop is shown which passes in front of the distribution plate 23, in the area of the distribution plate 23 and behind the distribution plate 23 respectively. The harvested crop, which is processed by the processing device (rollers 5.1 and 5.2), is picked up by the tine roller 20 and slung against the guiding device 22 in which case, as a function of the position of the cross-pieces 24, the harvested crop is distributed by the guiding device 22 on a width which essentially is between the width BA
and the width BP whereafter it is then fed to the pressing device (rollers 7). The distribution device can, of course, be constructed in such a way that the harvested crop is distributed by the guiding device 22 onto a width which is smaller than the 7 ~
WO 96/08133 PCT~PS5~03457 width BA, whereafter it is then fed to the pressing device (rollers 7). This has the advantage that also small quantities of harvested crop can be pressed reliably to a mat Also this embodiment is a feature of the invention.
Also the other device to influence the harvested crop, which is located behind the distribution arrangement, can be designed in such a way (for example, in a design as is ]~nown from hay swathers) that the processed harvested crop, coming from ~he processing device and the distribution arrangement respectively, is distributed (brought together) onto a width which is smaller than the width BA whereafter it is then fed to the pressing device. This has in particular then the advantage if the distribution arrangement is designed in such a way that i-t distributes the harvested crop coming from the processing device in fact onto a width BP which is greater than the width BA in which case, however, there would be no reliable formation of mats due to too small quantities of harvested crop. Thus, by means of the additional device, the processed harvested crop can again be brought together so that, on the one hand, the mat can be pressed reliably and, on the other hand, for example, by swinging the additional device in and out, all resulting quantities of processed harvested crop (small as well as large quantities) can be pressed reliably to a mat.
As is shown in Fig. 4, the cross-pieces 24 can be adjusted via the swivel lever 29. Here, to achieve the oscillating movement, it is conceivable that through an appropriate actua-tion of the hydraulic cylinder 30 by a not shown control, this puts the swivel lever 29 and thus the cross-pieces 24 in the oscillating movement, pivot 28 (sic). Alternatively and/or in addition to W0 96/08133 PCT/~P95/03~57 this, it is conceivable, by appropriate mountiny of the distribution plate 23 on a not shown pivot, to put the distribution plate 23 itself in the oscillating movement for which the hydraulic cylinder 30 then engages tlle distribution plate 23. This essentially vertical oscillating movement can be replaced or supplemented by an essentially horizontal oscillating movement which takes place by an appropriate hinging of the distribution plate 23 via the arm 26 and the elevator 27 respectively. It is likewise conceivable that to equalize the flow of harvested crop, the distribution plate 23 is put in the oscillating movement, while the width, on which the processed harvested crop is distributed, is set via the hydraulic cylinder 30 shown in Fig. 4. The oscillating movement of the distributio plate 23 and/or the cross-pieces 24 ta]~es place advantageously, leaving out, for example, the distribution screw 9 shown in Fig.
1 and the tine roller 20 shown in Fig. 2 respectively. But the oscillating movement can also be provided with the mentioned distribution devices.
To clean the tines of the tine roller and the cross-pieces respectively, it is conceivable to draw, for example, at preset time intervals or on putting into operation or after the use of the harvester, a comb-like device across the tines (provided these are arranged in a row in the circumferential direction and are not staggered) and across the cross-pieces respectively and thus to remove any dirt present.
Fig. 5 shows another distribution arrangement embodied accordiny to the invention.
This further embodiment of the guiding device 22 consists in that 7 ~
the distribution plate 23 already shown in Fig. 2 is hrought up into the outlet area of the processing device and has again cross-pieces 24 at its bottom side. In this embodiment, the arrangement of the tine roller 20 is eliminated because the processed harvested crop leaves the processing device at such a speed as a result of which the processed harvested crop is slung against the bottom side of the distribution plate 23, is distrib-uted by the cross-pieces 24 onto a larger (in the case of adjust-able cross-pieces also onto a smaller) width and is afterwards fed to the pressing device. In Fig. 5, it is shown that the distribution plate 23 is again attached to the elevator 27 on the arm 26, in which case this distribution plate 23 can also be arranged stationary in the area above the conveyer belt 6. It is also conceivable to swivel the distribution plate 23 according to Fig. 5 around a longitudinal axis at the end, facing the processing device or the pressing device, so that this distribution plate can be swung into the discharge area of the processing device or swung out of the latter. An arrangemen-t of the cross-pieces 24 on the distribution plate 23 can also here take place according to the arrangements (fixed or adjustable) shown in Figs. 3 and 4.
