BALE PRESS

Description

[0001] The present invention relates to a baler for agricultural crops according to the preamble of claim 1.

[0002] Harvesting machines are used in agriculture to collect crops such as hay or straw and, if necessary, process them further. Further processing can include chopping, pressing and / or packaging or wrapping the crop. In the case of a baler, the crop is pressed into bales (e.g. round bales or square bales), which can then be wrapped with binding material, either within the baler or in a separate bale wrapping device. String, nets or (e.g. in the case of grass) film can be used as binding material. In a round baler, the crop is normally picked up from the ground by a pick-up and transferred to a conveyor rotor, which transports the crop via a conveyor channel to the bale forming chamber or pressing chamber, where the actual pressing takes place.There, several pressing elements act on the crop, which also function as conveying elements and create a circular movement of the crop. Rollers, belts or chains are mainly used as pressing elements. Fixed-chamber presses are known in which the pressing or conveying elements are arranged according to a predetermined final bale size, with the actual pressing mainly taking place when the chamber is (almost) completely full. Variable-chamber presses are also known in which the effective size of the chamber is adjusted to the increasing amount of crop. Typically, one pressing element is designed as a belt that is held under tension and defines the majority of the baling chamber. Both the crop and the contaminants picked up with it can stick to the conveying elements, which can potentially impair the function of the harvester.Binding material that is supposed to be fed to the bale by a conveyor element can also stick to the surface of the conveyor element. In one type of round baler, the binding material (e.g. a net) is guided over a press roller, which also contributes to compressing the round bale and lies in contact with it. If everything goes according to plan, the binding material is carried along by the press roller, guided between the press roller and the round bale, and then adheres to the round bale. However, it can also happen that the binding material continues to stick to the press roller instead of to the round bale. In this case, it would wrap around the press roller, which would prevent the round bale from being wrapped and could lead to a stoppage or damage to the round baler.

[0003] To prevent this, it is known in the art to arrange a scraper adjacent to the bale roller. This is typically designed as a strip-shaped sheet metal part and is also referred to as a scraper plate or scraper bar. Its edge is arranged directly adjacent to the surface of the bale roller. As the bale roller rotates, material adhering to its surface, such as crop material, impurities, and / or binding material, is scraped off. The scraper can also act as a guide element, directing the scraped binding material toward the round bale. For optimal function of the scraper, its position and, in particular, its distance from the surface of the roller are crucial. To adjust this, the scraper can be connected to a stationary scraper support by several screws that are threaded through slots in the scraper and screwed into the scraper support. ZTAdditionally, threaded pins are screwed into the through holes of the scraper, which can clamp the scraper against the scraper carrier. However, there is a risk that the scraper will settle, i.e., move out of position. This can even happen when tightening the screws or later during operation of the round baler. After extended operation, the distance between the roller and the scraper can change due to wear on the scraper. There is also the problem of contamination of the threaded pins, which may have a hexagon socket, for example, which requires laborious cleaning before use.

[0004] EP 3 120 689 B1 discloses a scraper device for reducing adhesions to a roller of an agricultural round baler interacting with a bale, comprising a scraper bar, a scraper bar support, and at least one fastening means for connecting the scraper bar to the scraper bar support. The scraper bar has a rotatable adjusting means with means for adjusting the scraper bar along an eccentric guide track, which preferably extends in a helical or at least approximately circular involute manner from a region located at least near a center of the adjusting means toward an edge region of the adjusting means.At least one stationary guide means is arranged on the scraper bar support, which is received in a guide groove of the scraper bar, so that the scraper bar can be displaced relative to the stationary guide means, wherein by rotating the at least one rotatable adjusting means the scraper bar is adjusted linearly relative to the scraper bar support.

[0005] Further scraper devices are known from US 4 189 875 A, DE 694 04 235 T2, US 2016 / 340128 A1, DE 295 15 629 U1 and DE 38 25 190 A1.

[0006] The object of the invention is to propose reliable means for adjusting a position of a scraper of a baler.

[0007] The problem is solved by a baler for agricultural crops, having the features of independent patent claim 1. Advantageous embodiments can be found in the dependent claims.

[0008] For this purpose, a harvesting machine for agricultural crops is provided, comprising a movable conveyor element and a stripping device with a stripper carrier and a stripper, wherein a surface of the conveyor element adjacent to the stripper is movable past the latter in order to strip adhering material from the surface, and wherein a position of the stripper is adjustable relative to the stripper carrier.

[0009] The harvesting machine can, in particular, be a baler such as a round baler or a square baler. The term "baler" expressly includes machines that, in addition to pressing the harvested crop into bales, also bind or pack the bales. The agricultural harvested crop can, in particular, be stalk crops such as grass, straw, or hay. The harvesting machine has a movable conveyor element, i.e., the conveyor element is movable or movably mounted within the harvesting machine. The mobility can, in particular, be relative to a frame or a housing of the harvesting machine. The conveyor element can, in particular, be rotatably mounted and designed as a roller. However, the conveyor element could also be a belt or a chain. The conveyor element can be used to convey the harvested crop. Alternatively or additionally, it can, for example,Serve to convey a binding material or packaging material with which the bales are tied or wrapped, e.g., at least one string, a net, or a film. In addition to its conveying function, the conveyor element can also serve as a pressing element, i.e., be designed to press or compress the crop.

[0010] The harvesting machine also has a stripping device with a stripper carrier and a stripper. The stripping device is normally stationary throughout the operation of the harvesting machine, i.e. it is held in a fixed position relative to the frame or housing of the harvesting machine. The stripping device is positioned so that a surface of the conveyor element adjacent to the stripper can be moved past the latter in order to strip off material adhering to the surface. The surface of the conveyor element can in particular be the outer surface of a roller. However, it can also be, for example, the surface of a rotating belt. In certain circumstances, the surface can have a profile. During operation of the harvesting machine, the conveyor element moves in such a way that the surface is moved past the stripper. Since the stripper is located adjacent to the surface here (e.g.At a distance of less than 1 mm), material adhering to the surface is scraped off, i.e. removed from the surface. This material can be crop material, impurities such as soil or stones mixed with the crop, or even binding material used to tie or wrap a bale. In particular, the problem can arise that such binding material, e.g. film, string or net, adheres to a rotating roller, so that there is a risk that it wraps around this roller instead of being wrapped around the bale as intended. The likelihood of this increases with a higher bale density, which is increasingly desired.This danger can be counteracted by the scraper, on the one hand, scraping off the binding material itself, but on the other hand, also by scraping off crop material or contaminants that would encourage unwanted adhesion of the binding material to the conveyor element.

[0011] The scraper is usually plate-like and can be made of sheet steel, for example. In some embodiments, it can also be referred to as a scraper element, scraper plate, or scraper bar. It is the part of the scraping device responsible for the actual scraping of material and is therefore a wearing part. Accordingly, after a certain period of time, the scraper must be readjusted to restore what is considered an optimal distance from the surface of the conveying element. After extended use, the scraper may also need to be replaced. The scraper is carried directly or indirectly by the scraper carrier, which is generally designed to last the entire service life of the harvester and can be mounted in a fixed, unchangeable position relative to the surface of the conveying element.In contrast, the position of the scraper relative to the scraper support is adjustable. It is understood that adjusting the position of the scraper relative to the scraper support also means adjusting the position of the scraper relative to the surface of the conveying element. This adjustment allows, on the one hand, the position to be optimized during initial commissioning of the scraper, particularly the distance from the surface, and, on the other hand, the position to be readjusted if the scraper becomes worn.

[0012] According to the invention, the baler is characterized in that the stripper is connected to the stripper carrier by at least one adjustment arrangement which has a first adjusting element which is rotatable relative to the stripper carrier about an adjustment direction, and a second adjusting element which forms a helical gear with the first adjusting element and is displaceable relative to the stripper carrier in the adjustment direction and is designed to transmit force to the stripper. The respective adjustment arrangement thus has at least two elements. The first adjusting element, which could also be referred to as a rotary element, is rotatable relative to the stripper carrier about the adjustment direction. This means that the adjustment direction corresponds to the axis of rotation, so that one could also speak of an adjustment axis. The first adjusting element is mounted directly or indirectly on the stripper carrier in such a way that it can be rotated about the adjustment direction or adjustment axis.It interacts with the second adjusting element, which could also be referred to as a thrust element or slide element and which can be moved relative to the wiper carrier in the adjustment direction. The two adjusting elements form a helical gear, through which the rotary movement of the first adjusting element is converted into a displacement of the second adjusting element. One can also speak of a spindle gear, in which one adjusting element has the spindle and the other adjusting element has the spindle nut. Normally the first adjusting element has a first thread that interacts directly with a second thread of the second adjusting element. However, other designs are also possible, e.g. in the manner of a ball screw drive, wherein the force is transmitted between the adjusting elements predominantly by a plurality of intermediate balls.

[0013] The second actuating element is designed to transmit force to the wiper, i.e. when the second actuating element is moved, force is transmitted to the wiper, so that the wiper is adjusted in line with the movement of the second actuating element. The force can be transmitted indirectly or directly. In the latter case, there can be a frictional connection, a material connection and / or a form connection between the second actuating element and the wiper. It would also be conceivable for the second actuating element to be formed integrally with the wiper. Overall, the rotation of the first actuating element causes the wiper to be adjusted relative to the wiper carrier. The helical gear enables precise adjustment of the position of the wiper. Nevertheless, it can be implemented in a comparatively simple and robust manner.

[0014] According to a preferred embodiment, the first adjusting element has an external thread, and the second adjusting element has a cooperating internal thread. In other words, in this case, the first adjusting element has the spindle, and the second adjusting element has the spindle nut or forms the spindle nut. In particular, in this embodiment, the first adjusting element can be designed as a threaded pin whose longitudinal axis corresponds to the adjustment direction.

[0015] Advantageously, the stripper carrier can have an outer wall which at least predominantly encloses an interior space, wherein the first adjusting element is predominantly arranged in the interior space. The outer wall can be formed by one or more shaped sheet metal parts. It essentially defines the external shape of the stripper carrier and typically also forms a contact surface for the stripper. An interior space is formed within the outer wall which can accommodate parts of the adjustment arrangement. In this case, the first adjusting element is predominantly arranged in the interior space. The second adjusting element can also be arranged at least partially or predominantly in the interior space. The parts arranged within the interior space are largely protected from contamination or damage, whereby the functionality of the adjustment arrangement can be guaranteed for longer. Furthermore, the elements arranged in the interior space cannot disrupt the flow of crops.

[0016] In the above-mentioned embodiment, the first adjusting element can be guided through the outer wall and a retaining element can be arranged on the outside, via which a positive connection in the adjustment direction is established between the first adjusting element and the wiper carrier. The outer wall has a through-bore or through-opening through which the first adjusting element is guided. The retaining element is arranged on the outside and can either be formed integrally with the first adjusting element or as a separate component. In the former case, the retaining element could, for example, be a screw head, with the above-mentioned external thread of the first adjusting element being arranged on the shaft of the screw. Alternatively, however, a positive connection between the first adjusting element and the retaining element is also possible. For example.The retaining element can be designed as a castle nut, which is secured against rotation on the first adjusting element by a locking pin that passes through a through hole in the first adjusting element. When the retaining element is in position, its positive locking prevents the first adjusting element from being pulled through the outer wall.

[0017] To assist in rotating the first adjusting element, it preferably has a screw-type drive profile at at least one end. A wide variety of options are available; for example, the drive profile can be designed as a slot, Phillips, hexalobular socket, internal or external hexagon, internal or external square, or the like. During assembly, disassembly, or adjustment of the adjustment arrangement, the first adjusting element can be operated using a corresponding tool having a complementary profile. If the first adjusting element is predominantly arranged in the interior of the wiper carrier, the screw-type drive profile is preferably arranged on the outside of the outer wall so that it is easily accessible.

[0018] The adjustment arrangement preferably has at least one primary locking element for locking the first adjusting element relative to the wiper carrier. The locking prevents both displacement and rotation of the first adjusting element relative to the wiper carrier. Such a locking also leads (apart from any possible play between the two adjusting elements) to a locking of the second adjusting element, which in turn prevents displacement of the wiper. The presence of such a primary locking element can simplify the handling of the wiper device, since both the adjustment of the position of the wiper and the locking can subsequently be carried out in the same area, namely on the adjustment arrangement.

[0019] In particular, at least one primary locking element can be screwed onto the external thread of the first adjusting element, wherein the first adjusting element can be clamped against the wiper carrier by a screwing movement of the primary locking element relative to the first adjusting element. For example, the primary locking element can be designed as a hexagon nut that is screwed onto the external thread. Depending on the position of the primary locking element, this can, for example, come into contact with the outer wall of the wiper carrier. A washer or SKM washer can also be interposed between the nut and the outer wall.As described above, a first end of the first adjusting element can be guided outwardly through the outer wall on one side, with a retaining element arranged on the outside, while a second end on an opposite side is guided outwardly through the outer wall, where the primary locking element is screwed on. In interaction with the retaining element, the primary locking element, when screwed on further, can cause the primary adjusting element to be clamped. This means that the retaining element and the primary locking element create a frictional connection with the outer wall, which prevents further adjustment of the first adjusting element.

[0020] For various reasons, it can be advantageous if the stripping device has at least one secondary locking element, independent of the at least one adjustment arrangement, for locking the stripper relative to the stripper carrier. For example, during assembly or disassembly of the adjustment arrangement, the position of the stripper can be temporarily secured by the at least one secondary locking element. A further reason can be that the locking of the stripper is improved or the load on a primary locking element is reduced if additional locking is provided via at least one secondary locking element. Finally, it would also be possible for the at least one secondary locking element to be used instead of a primary locking element, in which case direct locking of the adjustment arrangement would not be possible.For reasons of stability, a plurality of secondary locking elements are normally provided, which are typically spaced transversely to the adjustment direction. In particular, at least one secondary locking element can be designed as a screw. The wiper can have an elongated hole extending in the adjustment direction and through which the screw is passed. A bore with an internal thread can be formed in the wiper carrier, into which the screw is screwed to lock the wiper. The elongated hole can adjoin a groove on a side of the wiper facing away from the wiper carrier, wherein the groove is dimensioned to accommodate the head of the screw.

[0021] As already indicated above, there are different options for transmitting force from the second adjusting element to the wiper. According to a preferred embodiment, the second adjusting element engages in a recess in the wiper with a positive fit. The recess is of course formed on a side of the wiper facing the wiper carrier. It is preferably designed as a blind recess so that the second adjusting element is shielded from the opposite side. This also prevents dirt or other material from penetrating the wiper at this point and, for example, into the interior of the wiper carrier. In order to achieve the most immediate response possible of the wiper to adjustment movements of the adjustment arrangement, the second adjusting element is preferably accommodated in the recess without any play or with minimal play (e.g., less than 1 mm).The second adjusting element could be screwed into the recess, but preferably it is only inserted, which allows the wiper to be assembled or disassembled as required without dismantling the second adjusting element or other parts of the adjustment arrangement.

[0022] To prevent the second adjusting element from rotating when the first adjusting element rotates, the wiper carrier has a guide slot in which the second adjusting element is guided in the adjustment direction. The guide slot is normally formed in the aforementioned outer wall of the wiper carrier. Its dimensions are adapted to the dimensions of the second adjusting element so that the latter can pass through the guide slot or be accommodated therein, whereby normally there is at most a slight play between the second adjusting element and the guide slot. On the outside of the guide slot, the second adjusting element can engage in the recess of the wiper, as described above.

[0023] In principle, numerous advantages of the invention can be achieved with a single adjustment arrangement. However, it is preferred that the scraper is connected to the scraper carrier by a plurality of adjustment assemblies spaced apart transversely to the adjustment direction. In particular, exactly two adjustment assemblies can be provided, which can be arranged, for example, at opposite end regions of the scraper. By means of two adjustment assemblies, it is possible, for example, to adjust the positions of two spaced-apart points on the scraper independently of one another (within certain limits). This not only makes it possible, for example, to adjust the distance between the scraper and the surface of the conveying element, but it can also be ensured, for example, that the scraper (or a scraper edge thereof arranged adjacent to the conveying element) is aligned exactly parallel to this surface. This could therefore, for example,possible deformations, misalignments or manufacturing defects in other components must also be compensated.

[0024] The invention is described below with reference to figures. The figures are merely exemplary and do not limit the general concept of the invention. They show Fig. 1 a sectional view of a roller baler according to the invention; Fig. 2 a perspective view of an assembly of the roller baler from Fig. 1 ; Fig. 3 a perspective detailed view of the assembly from Fig. 2 ; and Fig. 4 a sectional view of the assembly from Fig. 2 .

[0025] Fig. 1 shows a harvesting machine, more precisely a roller baler 1, according to the present invention. The roller baler 1 is intended in a known manner to be pulled by a tractor (not shown). However, the invention is not limited to towed or carried harvesting machines, but also includes self-propelled harvesting machines. Apart from running wheels 2 on which the roller baler 1 stands, various conveying elements 5 - 10 are movably mounted on a frame of the roller baler 1. In a direction of travel F, a pick-up 5 can be seen at the front, which in operation (relative to Fig. 1 ) rotates clockwise and serves to pick up crops, more specifically stalks such as straw, hay, or grass, from the ground. From the pick-up 5, the crops are transported to a conveyor rotor 6, which rotates counterclockwise. It has a plurality of tines that grip the crop and transport it further, against the direction of travel F and slightly upwards, through a conveyor channel 13. Instead of the conveyor rotor 6, a cutting rotor could also be used, which not only conveys the crop but also chops it up.

[0026] Three press rollers 7, 8, 9 and at least one press belt 10 (possibly also several press belts arranged side by side perpendicular to the plane of the drawing) define a press chamber 18 of variable size, in which a crop bale 50, shown schematically here, is formed from the crop. A gap 14 is formed between a first press roller 7 and a second press roller 8 arranged underneath. A stripping device 20 is arranged below the second press roller 8, the structure and function of which will be explained below with reference to Fig. 2 bis 4 explained. Between the stripping device 20 and a third press roller 9, the conveyor channel 13 opens into the press chamber 18. The press rollers 7-9 rotate clockwise during operation of the roller baler 1, as do a plurality of guide rollers 11, over which the at least one press belt 10 is guided. Two of the guide rollers 11 are assigned to a belt tensioner 12, which ensures sufficient tension of the press belt 10 regardless of the size of the crop bale 50.

[0027] The pressing rollers 7 - 9 and the pressing belt 10 cause the crop bale 50 to rotate counterclockwise and simultaneously compress the crop, which can already be pre-compacted in the conveyor channel 13. When the crop bale 50 has reached a predetermined maximum size, it is wrapped with a binding material (not shown here) (e.g., a film or net) within the pressing chamber 18 before it is finally ejected rearwardly against the direction of travel F by opening a tailgate 17 of the roller baler 1. First, the binding material is grasped by a feed spout 15, which is guided by a guide slot 16 and feeds the binding material through the gap 14 to the crop bale 50.From there, the binding material is pulled between the crop bale 50 and the second press roller 8 by the rotation of the latter, ideally adhering to the crop bale 50 and then being wrapped around it by its rotation. Under certain circumstances, however, the binding material may adhere to a surface 8.1 of the second press roller 8, so there is a risk that it will be wrapped around the second press roller 8. This is counteracted by the stripping device 20.

[0028] The stripping device 20 has a stripper carrier 21 to which a plurality of stripper fingers 22 are welded. Each stripper finger 22 engages between two tines of the conveyor rotor 6 and thus counteracts the adhesion of crop material to the conveyor rotor 6. Furthermore, a stripper 30, which can also be referred to as a stripper plate or scraper bar, is connected to the stripper carrier 21 such that it is arranged with a stripper edge 30.1 adjacent to the surface 8.1 of the second press roller 8. When the second press roller 8 rotates during operation, its surface 8.1 is guided past the stripper 30 at a close distance, thereby stripping any adhering material from it. The stripper carrier 21 has an outer wall 21.1 made of sheet steel, which at least predominantly surrounds an interior space 21.2.

[0029] The optimal function of the scraper 30 depends on the adjustment of its distance from the second press roller 8. For this purpose, two adjustment arrangements 40 are provided at opposite ends of the scraper carrier 30, which allow a safe and precise adjustment of the scraper 30. As shown in the sectional view of Fig. 4As can be seen, each adjustment arrangement 40 has a threaded pin 41 as a first adjusting element. This is guided through two smooth through-bores 21.3, 21.4 in the outer wall 21.1 of the wiper carrier 21. Accordingly, the threaded pin 41 is rotatable relative to the wiper carrier 21 in an adjustment direction V. In addition, an external thread 41.1 of the threaded pin 41 engages with an internal thread 46.2 in a through-bore 46.1 of a bolt 46, which forms a second adjusting element. The threaded pin 41 and the bolt 46 thus interact as a helical gear. The bolt 46 is guided in a guide slot 21.5 in the outer wall 21.1 in the adjustment direction V and is also positively received in a blind recess 30.2 in the wiper 30.

[0030] The threaded pin 41 is secured on the one hand on the outside of the wiper carrier 21 by a castle nut 42 and a cotter pin 43; on the other hand, a lock nut 44 is screwed on the outside with an interposed SKM washer 45. The castle nut 42 therefore acts as a retaining device. The SKM washer 45 and the lock nut 44 are used here as the primary locking elements. When the lock nut 44 is tightened, the threaded pin 41 is clamped against the wiper carrier 21 and secured against rotation due to the frictional connection via the SKM washer 45. By loosening the lock nut 44, the threaded pin 41 can be rotated relative to the wiper carrier 21 in the adjustment direction V, which is possible in the example shown here using a hexagon socket profile 41.2. The rotation of the threaded pin 41 leads to a displacement of the bolt 46 in the adjustment direction V and thus also to a corresponding displacement of the wiper 30.

[0031] The scraper 30 is prevented from lifting off the scraper carrier 21 by a plurality of screws 31 that pass through elongated holes within the scraper 30 and are screwed into threaded holes in the scraper carrier 21. The corresponding screws 31 can be tightened as additional security once the adjustment of the scraper 30 has been completed. The screws 31 are therefore used here as secondary locking elements. When the adjustment arrangement 40 is first installed, the screws 31 can also be used to temporarily secure the scraper 30 until the threaded pin 41 has been screwed into the bolt 46 and secured by means of the castle nut 42. Both the threaded pin 41 and the bolt 46 are arranged predominantly within the interior 21.2 of the scraper carrier 21 and are thus protected from contamination. Conversely, any impairment of the crop flow by the adjustment arrangement 40 is also excluded.In order to shield the adjustment arrangement 40 from the outside, the wiper carrier 21 has a detachable protective hood 23, which can be attached and, for example, screwed tight after the wiper 30 has been adjusted.

[0032] The screw gear of the individual adjustment arrangement 40 allows a precise adjustment of the distance between the scraper 30 and the surface 8.1, whereby the independence of the two adjustment arrangements 40, which are arranged at opposite end regions of the scraper carrier 21, also allows the parallel alignment of the scraper edge 30.1 to the surface 8.1 to be adjusted, even if, for example, the scraper carrier 21 should deviate from a predetermined position relative to the second press roller 8.
