A driver transporting and pressing roller (3) is fixed in the front part of a colelcting press chamber (5) before the winding chamber (2). The roller (6) is veriable in height on the spring-loaded upper wall (7) of the collecting press chamber (5), and to lower wall (8) is either rigidly fixed or is able to yield relative to the upper wall (7). USE/ADVANTAGE - The compression of the material is either largely uniform throughout the whole bale, or can be altered as desired from the inner to the other parts.

Description

The invention relates to a round baler with one of the wraps chamber upstream collection chamber, in which during binding and ejecting the finished round bale of further harvested crop is introduced well, with a press assigned to the collecting channel roller and a separator provided at the inlet to the winding chamber ment.

With round balers of this type, it becomes swathy on the ground lying crop continuously taken up, a prechamber and then discontinuously a press chamber for generating and Binding of the round bale to be ejected afterwards fed.

In a method known from DE-PS 37 34 850 to one proper roll baler should do this while closing with the Binder and ejection of the previously made bale included mene Gut both in a feed channel by means of a press roll also afterwards until the bale chamber is closed in itself be cached. It is unfavorable that the fixed design of the feed channel in the same no on possibility to adjust to the very different and always here there are changing strengths of the swath to be picked up, hence the Depending on the swath thickness, pressing continuously from insufficient to strongly done. As a result, both overuse of the involved press assemblies and high power requirements zen on as well that the pressing of the goods in portions to ge is ring and thus the required uniformity in the compression efficiency of the bale produced is not guaranteed. The press roller should also be able to be stored resiliently, this is but their pressing action is not adjustable and their position at the firmest channel undefined. It is also disadvantageous that the  Pressing of the goods partially dissolves after leaving the press roll, because the pressed material strand, which acts as a pressure strand against one after common, elastic web starts up, the same against resistance bulge inwards so that the strand is not positively guided and unevenly occupies an enlarged space. Such Presses could therefore not be spread.

It is also known in round balers during tying and ejecting a finished bale from the conveyor switch off the upstream chamber, so that in it continuously good supplied by reception and funding institutions is saved next. Since the material is not heavily compressed, the chamber would have to be made very large, with which the press would be an inappropriately lengthening size, and that one Larger volume occupying, temporarily in the press room brought good from the antechamber cannot ge enough in the latter be pressed so that the bale has a particularly soft core points (DE-OS 21 40 299).

In another, known round balers with a press prechamber upstream of the chamber are fixed below, drivable rollers and above those which change the Size of the antechamber pivoted to the lower rollers are provided. In order to pre-compress the material or to trans porting, the direction of rotation of these rollers is changed.

The disadvantage here is that the pre-compression is not strong enough and the good is not pressed into one another, the size the prechamber only to an estimated size before operating is adjustable and this is not large in a little complex enough can be designed (DE-OS 33 11 330). That is insufficient compressed and not matted material relaxes also strong after the transfer to the press room, making this the Batches forming the core of the later bale no longer on one high compression during the subsequent production of the whole bale can be brought both in terms of the whole, he as well as a uniform density without increased Inclusion of air especially for bales of silage because of the Ge post-proofing is disadvantageous.  

To be able to save the quantity of goods to be stored and there to keep the antechamber as small as possible is one also known round baler (DE-OS 34 31 389) of the bandage Process already started for the bale if the material supply is still he follows. The loose material stored in the antechamber is replaced by a Conveyor drum quickly brought into the press room, where it is not more can be pressed enough and thus a soft core of the Bale forms.

It is with all these known round balers with antechambers disadvantageous that both no automatically uniform pressing of the Good things already exist in the antechambers regardless of the difference Lichen strength of the swath to be recorded is also that in addition, a different strength of the Press evenly throughout the entire bale or inside and outside different depending on different types of goods such as straw, hay, Semi-hay or the like not or not in a quick and easy way is possible or adjustable.

Finally, it should be pointed out that with square bales producing field crops a tine rotor the picked up Conveying and pre-pressing good material into a pre-press channel, see DE-OS 35 00 010 and DE-OS 34 45 0159 being the latter proposal the height of the pre-press channel is adjustable. These sizes are position would, however, always have to be manually adapted to the needs which would result in a high level of operating effort. A Always optimal setting of the channel size with the often changing existing swath strength and the fast running Betriebsver is therefore not possible, there is a risk that that temporarily the crop is very strong either with large swaths is pressed, settles in the pre-press channel and be Further transport then requires a lot of power and components are overloaded or an excessively stable, expensive design must be selected or that the pressure is not sufficient.

The invention has for its object a continuous good Lich receiving round baler through which the Ver Sealing of the goods in the entire bale area is either largely is present evenly, with both the often changing strength of the crop swaths to be picked up automatically at the desired vehicle speed is balanced as well as a different ver the strength of pressing the crop in the round bale at Ver no need to convert to different ones Channel sizes are already taken into account in the antechamber, and both with respect to the entire bale as well as different in the desired gradation in its inner to outer areas.

This object is achieved in that an is driven transport and press roller in the front area of a height resilient in adjustable load to the crop extensively mounted, upper wall of a winding chamber Collective press channel is permanently assigned, with the lower wall which is rigidly arranged or one corresponding to the above opposite wall can experience evasive displacement.

Further, special embodiments of the invention are characterized by Features of the claims characterized.

The advantages achieved with the invention are in particular in the fact that in a non-stop mode of operation of round balers regardless of changing operating conditions when desired Working speed and without one for bale production required observation including operating effort round bales are to be produced, with either the inside or the like outer zones as desired either in high uniformity the density or a selected, different density exists or in this case in adaptation to the needs of different Goods round bales also consistently of different baling densities each Weil can be generated without installation work and Overloads in the feed and pre-press equipment and thus excessive power peaks are avoided, the length of the Collection press channel can be kept relatively short because of a sufficient storage volume of the same for the during the  Tying and ejecting the finished round bales continues continuously Lich harvested crop if necessary by evading his upper and lower wall due to the pressure of the crop follows and at excessive pressure to secure the components against Overload a shutdown of the operation is initiated.

According to Fig. 1, a round baler 1 has a supply channel 6 which opens into a Sammelpreßkanal. 2 In the front area of the collecting press channel 2 , a transport and press roll 3 is permanently assigned to an upper wall 1 of the collecting press channel 2 , the transport and press roll 3 and thus also the upper wall 1 about a pivot point 12 formed near an inlet opening 10 to a winding chamber 9 are stored and a hydraulic cylinder 14 both on it and on a frame 39 of the round baler 1 pivotally connected to the former with a required to achieve a desired compression density against a load from a pick-up device 30 and the feed channel 6 crop 26 to be applied so that the desired pressure of the same he is enough. In the pressure oil supply line, not shown, a corresponding pressure gas container is connected in a known manner, where good 26 is compensated for by deviations in the strength of the supplied strand of the crop. The oil pressure is pre-selectable by a switching and pumping device and a corresponding pressure reducing valve, whereby it can be manually or programmed variably adjusted during the operation, e.g. B. to an adapted to the crop to be processed 26 value of the pressing and additional Lich if desired to different pressing values, depending on whether the inner or outer region of a round bale 38 is wrapped.

Instead of the programmed hydraulic system described with the hydraulic cylinders 14 and 49 can also be a simplified, semi-automatic setting for pressing the crop 26 in the collecting press channels 2 , 2 a, 2 b and to enable the relatively large displacements of the upper wall 7 and a lower 33 to these mechanically acting, adjustable in load Federein directions can be assigned directly or via pressure or traction means, the adjustment can be done manually or controlled by external force.

Side walls 51 of the collecting press channel 2 are arranged at an angle α such that they extend slightly to the winding chamber 9 so that the transport of the pressed crop 26 is favored by lower frictional conditions in the collecting press channel 2 , as is illustrated in FIG. 5 .

A lower wall 8 is rigidly arranged and has a trough 21 opposite to the transport and press roll 3 , into which press teeth 4 of the transport and press roll 3 protrude in a depression 28 , as shown in solid lines, the upper wall 1 also being one Subscript 28 has taken. This subscript 28 results, for. B. with a small amount of crop due to small, pick up the swaths per route traveled and correspondingly low driving speed. On the other hand, a position shown in broken lines shows a high position 29 of the transport and press roll 3 with the upper wall 7 of the collecting press channel 2 , as occurs when the crop is picked up and the driving speed is corresponding.

As shown in FIGS. 1, 2 and also 6, 9 further illustrate, the crop is taken 26 from the transport and pressure roller 3, wherein the same to each other by a plurality of spaced and helically staggered Preßzähne 4 which are arranged on a central pipe 5 are pressed together according to the load by the hydraulic cylinder 14 and matted into each other. Here at have front flanks 40 of the pressing teeth 4 in a known manner on such a curved contour that the crop 26 in cooperation with a stripping grid 41 , which is approximately tangent to the outer diameter of the central tube 5 , as a continuation of the wall 7 ren in the collecting press channel 2 remains. The strand of material compacted in this way is conveyed through the collecting press channel 2 into the winding chamber 9 and there initially forms a small core 31 of the later pressed round bale 38 , as shown in FIG. 9.

The collection press channel 2 is shut off from the winding chamber 9 at the inlet opening 10 by pivoting in a separating element 21 . The separating element 21 moves on a circular path 23 , the center point 22 of which deviates from a center point 24 of an approximately circular inner surface 25 of the separating element 21 so that this inner surface 25 stands out when the separating element 21 is pivoted back from the crop 26 , as a result of which the following Opening the collecting press channel 2 against the pre-pressed crop 26 facilitated. A tip 11 of the separating element 21 can be designed to be knife-sharp, so that the separation of the crop strand can be carried out easily.

The crop 26 which is continuously picked up and stored in the collecting press channel 2 during the binding process and the ejection of the round bale 38 is deliberately compacted to the desired thickness by the transport and press roller 3 and matted into one another. A control system determines the accumulating pressure or force ratios in the collecting press channel 2 during the binding process and the bale ejection and effects the control of a swing-out process of the upper wall 7 . At the same time, overloads in the feed and pre-pressing devices are avoided by overload protection, such as, for example, when a predetermined maximum pressure value is exceeded. B. a slip clutch for a main drive shaft of the round balers 1 , 31 and 65 responds. The crop 26 is also compressed compressively in the closed collecting press channel 2 , so that any air spaces formed are filled or areas with low press density are compensated to the desired.

While the collecting press channel 2 is being filled, the round bale 38 is finally bound and ejected. After closing the roll chamber 9 or time very shortly before the separating element 21 is again ge opens, so that the left in Sammelpreßkanal 2, prepressed crops 26 flows from the same in the winding chamber 9 by the conveying action of the transport and pressure roller. 3

By implementing a well-dependent, optimal compression of the crop 26 in the collecting press channel 2 , it is possible to achieve a uniform or desired staggered density of the round bales 38 in the wrapping chamber 9 .

According to the embodiment shown in FIG. 2, a lower wall 33 of a collecting press channel 2 a is movably arranged for a further enlargement of its good storage volume by a fixed pivot point 34 in a round baler 31 , whereby it is connected to a connecting element 35 to the winding chamber 9 , which is close to the Bottom edge of an inlet opening 10 a lying pivot point 36 is rotatably mounted bar. This connecting element 35 can be designed as a pivotably closed plate or as a pivotable grid wall and can be pivoted by a hydraulic cylinder 49 in a manner corresponding to the top wall 1 , under adjustable load, from a high position 53 to a low position 54 , as a result of which the lower wall 33 also moves from one Superscript 55 reaches a subscript 56 . During the continuous supply of material in the winding chamber 9 is located between the lower edge of the inlet opening 10 a and an end region 50 of the lower wall 33 connec tion element 35 on the latter.

By Verschwenkungsmöglichkeiten the top wall 7 upwardly in the embodiment of Fig. 1 and the possibility of the bottom wall 33 shown down in accordance with the embodiment of FIG. 2, the storage volume of the Sammelpreßkanäle 2, 2 a, in compliance with the desired pre-compression so as to increase, that it is possible to continue to record during the closing of the collecting press channel 2 or 2 a for binding and ejecting the finished round bale 38 further crop 26 even in strong swaths and high driving speed.

On the upper wall 7 of FIG. 3, in addition to the width of Sammelpreßkanals 2 evenly distributed a plurality of knives 42 mounted at the front project into the Sammelpreßkanal 2 and so the flowing him crop 26 at least partially cut, if desired for reasons of crop processing is. These knives 42 are attached to an axis 43 and for cases in which a cutting of the crop 26 is not desired, from the loading area of the collecting press channel 2 to a pivoting position 44 to ver.

In a variant of the embodiment according to FIG. 3, FIG. 4 shows a solution in which a plurality of knives 45 arranged uniformly distributed over the width of the collecting press channel 2 are provided attached to an axis 46 of the lower wall 8 , which are also in an off position if required 41 are to be pivoted.

To increase the cutting performance, it is further proposed to provide both the knives 42 on the upper wall 7 and the knives 45 on the lower wall 8 as a desired embodiment, so that extensive cutting through of the same is possible even with a stronger strand of crop.

Referring to FIG. 6 is a top wall 7a of a Sammelpreßkanals 2 of a round baler 65 b in front and behind disposed vertically movable 60 and 61 by means of a respective pair of outside link, wherein the front link 60 β by as much longer and / or in such a different angular position to are performed γ of the rear arms 61 from or arranged that, when going high of the upper wall 7 a into a high position 63 b from a low position 62 for enlarging the Sammelpreßkanals 2, this is then higher in front than in the back, where b with an inlet opening 10 for Winding chamber 9 is also appropriately enlarged here. This is advantageous so that in the higher positions of the upper wall 7 a of the collecting press channel 2 b, the inlet opening 10 b is both not so large that the inflowing crop 26 abuts on an inlet opening 10 b upward-limiting roller 64 and thus a jam arises, but that this inlet opening 10 b is increased with respect to the upper wall 7 a of the low setting 62 compared. As a result, the inflow of the crop 26 located in the collecting press channel 2 b into the winding chamber 9 is facilitated. The upper wall 7 a is moved by a Hydraulikzylin 52 , which attaches to the front pair of links 60 .

In the positions of the upper walls 7 , 7 a in the lower position 28 or 62 and the lower wall 8 and the lower wall 33 in the high position 55 , the collecting press channels 2 , 2 a, 2 b have a cross section such as that for relatively small amounts of crop traveled distance of the round balers 1 , 31 , 65 is sufficient, whereas with middle positions of the upper and lower walls 7 , 7 a and 8 , 33 these cross sections are usually large quantities of crop to be processed and finally cut sufficient storage space at the largest possible collecting channel cross from closing to reopening the collecting press channels 2 , 2 a, 2 b for the harvest to be collected well 26 for the complete binding and ejection of the round bales 38 to the winding chamber 9 is available.

A lower wall 66 of the collecting press channel 2 according to FIG. 1 is designed as a rolling floor 61 in order to facilitate the flow of the pressed crop 26 , its rollers 68 not being driven as passive conveying elements or for further increasing the flow of the crop 26 a part or easier all rollers 68 can be driven accordingly.

In the exemplary embodiment according to FIG. 8, a lower wall 69 is provided with slots 70 into which a plurality of tines 71 of a conveyor rake 72 enter, as a result of which the crop flow is forcibly initiated for the tines 71 at the selected speed.

Through which the flow of crop material 26 promotion means, such as roll floors 61 and conveying rakes 72, both the dynamic effect on the Sammelpreßkanälen 2, 2 a, 2 b reaching crop material 26 in order to achieve a strong pressure without voids or schwachgepreß te parts to increase as well as a disturbed influence in the winding chamber 9 and fixing the crop 26 in the collecting press channels 2 , 2 a, 2 b and in the area of the inlet openings 10 , 10 a, 10 b prevented. Depending on the operating conditions, both during the filling of the closed collecting press channels 2 , 2 a, 2 b, the driven rolling floor 67 or the conveyor rake 72 for a short time in order to achieve an impact-like and thus reinforcing pressing action, and also that the same to support a quick and disturbing tion-free passing and emptying of the open collecting press channels 2 , 2 a, 2 b can be switched on.

In the round balers 1 , 31 and 65 is a supply spool 20 for a bandana 19 is arranged under the collecting press channels 2 , 2 a, 2 b, see in particular Fig. 9. The bandana 19 is deflected by a star roller 58 to a drive starwheel 57 , from where it is located in a guide channel 59 . For instance, if only one layer of crop material is to be wound 26 on a round bale 38, 19 of the inlet opening by a switching pulse, the tack cloth fed 10 a and lies down, deflected by a lower support roller 76 on the rortierenden round bale 38 to about the point P in the amount an obe ren support roller 48 of the inlet opening 10 a, with the registered number of revolutions of the drive star wheel 51 made as a result of a pulse of the program circuit of the system then the separating element 21 closes the inlet opening 10 a, according to a position 75 of the separating element 21 .

Following this, the round bale 38 is still so long rotated until the further enclosing binding fabric 19 the residual amount of has covered enough in the inlet port 10a located crop 26 and the beginning of the same, a sufficient hold of the binding fabric 19 on the round bale 38 to ensure that the tie 19 is then separated by means of a device and the round baler 38 is ejected.

This type of arrangement of the bandage device 19 , 20 , 57 , 58 , 59 under the press channels 2 , 2 a, 2 b enables a shortening of the setting time for the round bale 38 , while crop 26 can be picked up but not introduced into the winding chamber 9 , since be already while winding up the last layer of the crop 26 in almost the entire circumferential area, except for the inlet opening 10 a, the binding process has already been initiated, and the direction of rotation during bale production according to arrow 13 for tying does not need to be changed, as other proposals have made known.

Fig. 9 thus shows the round baler 31 according to FIG. 2, both with a fully wound round bale 38 and with a pivoted separating element 21 for closing the inlet opening 10 a and a collecting press channel 2 a brought to maximum volume, since the upper wall 7 is in the high position 29 and the lower 33 are in low setting 56 .

Figs. 1, 2, 6 and 9 show that it is particularly useful if the inventive Sammelpreßkanäle 2, 2 a, 2 b on the round baler 1, 31 are applied 65, in which the winding chamber 9 in the beginning of winding is small, as is the case with known systems with winding tapes 74 , since here no expansion of the pressed crop 26 introduced from the collecting press channel can occur. However, the invention also brings sufficient advantages when using the round balers with a rigid wrapping space, since the combination of the pressing and felting by means of the transport and press roller 3 designed with pressing teeth 4 means that the pressure on the crop 26 is relaxed or the pressure is released when the same is left for a short time, without any environment takes on small dimensions.

The invention is not limited to the exemplary embodiments explained, the individual features can be used mutatis mutandis in the context of the invention. The upper wall 7 a according to FIG. 6 arranged over two pairs of links can also be used with the round baler 1 or 31 .

Air pressure cylinders can also be used instead of hydraulic systems with hydraulic cylinders 14 , 49 or mechanical spring accumulators. It is also advantageous that the roller 64 and / or the support roller 76 to the influence of the crop 26 in the Wickelkam mer 9 are pivoted so that the inlet opening 10 is enlarged for the time of influence.
