COMBINE HARVESTER

Description

[0001] The invention relates to a combine harvester for carrying out an agricultural harvesting process according to the preamble of claim 1.

[0002] Often, the non-grain components harvested by a combine harvester during the harvesting process are spread directly onto the harvested field, for example, to improve soil quality. It is important that the harvested material, in this case the straw, is of a type and ejected in such a way that it decomposes easily, so that its nutrients are available in the following growing season. Decomposition is influenced by various factors, including external influences (such as weather) and soil composition (such as microorganisms), but especially by the distribution of the harvested material on the field. For example, if the harvested material is distributed homogeneously across the working width of the combine harvester, decomposition is promoted.

[0003] A systematization of crop distribution on the field is shown in DE 10 2014 113 965 A1, according to which distribution is carried out using user-selectable distribution strategies. This fundamental method of controlling the distribution system leads to high reproducibility in optimizing crop distribution on the field. A refinement of this strategy-based control of the distribution system is the subject of DE 10 2016 118 187 A1, which provides for structuring a higher-level distribution strategy into subordinate sub-strategies.

[0004] While the known control-related measures provide a robust control-related basic structure for a reproducible distribution of harvested crops on the field floor, a number of scenarios remain unaccounted for.

[0005] The invention is based on the problem of designing and further developing the known combine harvester in such a way that the distribution of harvested crops on the field floor is further optimized.

[0006] The problem is solved according to the invention with the characterizing features of claim 1.

[0007] The essential consideration is that the throwing characteristics of the distribution arrangement can be adjusted with a few combinable sub-strategies in such a way that a large number of important boundary conditions, such as a slope in the field, are covered.

[0008] In detail, according to the invention, it is proposed that the driver assistance system is configured to optimize the control of the crop distribution arrangement of the sub-strategies "throwing direction correction" and "inclination-dependent crop distribution" and "crop distribution in longitudinal direction" and "crop distribution in transverse direction" with regard to at least one optimization criterion.

[0009] Numerous possibilities are conceivable for at least one optimization criterion, which may also be user-defined. According to the invention, the optimization criterion is a high degree of uniformity in the distribution of the harvested crop in the transverse direction of the combine harvester and / or in the longitudinal direction of the combine harvester.

[0010] The term "longitudinal direction" here always refers to the longitudinal axis of the combine harvester, along which the combine harvester's direction of travel is also aligned. The longitudinal direction of the combine harvester also preferably provides the axis of symmetry for the combine harvester's chassis.

[0011] The sub-strategy "throwing direction correction" aims to optimize the throwing direction, specifically the horizontal and / or vertical throwing direction. It's important to remember that each throwing direction is always composed of the vector components of a horizontal and a vertical throwing direction.

[0012] In the inventive sub-strategy "slope-dependent crop distribution", "slope" refers to a slope of the field and thus of the combine harvester with respect to the direction of gravity. Such a slope is always associated with a change in the crop distribution on the field, which must be compensated for accordingly by the driver assistance system.

[0013] The sub-strategy "slope-dependent crop distribution" is advantageous, for example, when driving over a hill or through a depression, where an adjustment of the vertical throwing direction is required in order to meet the respective optimization criterion.

[0014] The inventive sub-strategy "crop distribution in longitudinal direction" is aimed at a reproducible crop distribution in the longitudinal direction of the combine harvester, at least by adjusting the vertical throwing direction and / or the throwing speed.

[0015] Advantageous scenarios for the application of the sub-strategy "crop distribution in the longitudinal direction" are addressed in claims 3 and 4. In each case, the aim is for the crop distribution on the field floor in the longitudinal direction of the combine harvester to correspond to predetermined optimization criteria.

[0016] The inventive partial strategy "crop distribution in the transverse direction" relates to the reproducibility of the crop distribution in the transverse direction of the combine harvester at least by adjusting the horizontal throwing direction and / or the throwing speed.

[0017] The further preferred embodiments according to claims 5 to 10 relate to advantageous applications for the sub-strategy "crop distribution in the transverse direction".

[0018] In the particularly preferred embodiment according to claim 10, the crop distributions on the field floor of two adjacent tracks are arranged to connect to one another. This ensures a uniform crop distribution on the field floor even across the tracks.

[0019] The implementation of the proposed sub-strategies can be model-based and / or sensor-based. In the preferred embodiment according to claim 11, for example, a sensor arrangement is provided for detecting the crop distribution on the current driving lane and / or on adjacent driving lanes, based on which the driver assistance system optimizes the control of the crop distribution. This results in a control system that can also take into account unmapped field features, such as unforeseen obstacles.

[0020] In principle, the distribution width on the field can be adjusted by synchronizing the throwing direction and throwing speed ranges, as proposed in claim 12. Precise adjustment of the distribution width plays a particularly important role in coordinating the distribution of the harvested crop onto the adjacent wheel tracks mentioned above.

[0021] To ensure that the operator is properly involved in the distribution of the harvested crop on the field, the further preferred embodiments according to claims 13 to 15 relate to equipping the driver assistance system with an input / output device with which, for example, individual distribution requests according to claim 15 can be entered by the user.

[0022] The proposed solution enables the documentation and storage of information that may be useful in subsequent agricultural harvesting processes on the same field or on other fields. Accordingly, claim 16 proposes that the driver assistance system generates corresponding georeferenced harvesting process data and stores it locally or remotely at the machine.

[0023] The proposed solution can be used with particular precision and efficiency according to claim 17 if the combine harvester has independently controllable distribution units, preferably in the form of radial distributors. However, it is also conceivable that two symmetrically controlled distribution units are provided. Finally, in a particularly simple variant to implement, the distribution arrangement could be equipped with a single distribution unit aligned with the longitudinal direction of the combine harvester.

[0024] The invention will now be explained in more detail with reference to a drawing that illustrates only one embodiment. The drawing shows Fig. 1 shows a proposed combine harvester in a schematic side view, Fig. 2 shows the arrangement according to Fig. 1 in a top view and along section line II-II, Fig. 3 the arrangement according to Fig. 2 in a top view and along section line III-III, Fig. 4 the arrangement according to Fig. 1 in a second harvesting situation in a top view as well as along the section line IV-IV and Fig. 5 the arrangement according to Fig. 1 in a third harvesting situation in a side view a) while driving over a crest and b) while driving over a depression.

[0025] The in Fig. 1 The schematically depicted combine harvester 1 serves to carry out an agricultural harvesting process. It has several working units, which will be explained later, and a driver assistance system 2 for controlling at least some of the working units. As working units, the combine harvester 1 incorporates, for example, a header designed as a grain header 3, which is connected to an inclined conveyor 4 in a manner known per se. The transverse conveyor 5 of the grain header 3 transfers the harvested crop 6 from it to the inclined conveyor 4, which in turn transfers the harvested crop 6 to the threshing unit 7. The grain separated in the threshing unit goes directly into the grain tank 8; a remaining partial stream of grain, short straw, and chaff is directed to a separating unit 9, where the grain is separated from the short straw and chaff.The partial stream, consisting primarily of short straw and chaff, is fed to a chopping device 10, where the straw components are chopped and then fed to a crop distribution system 11. A further partial stream of grain, short straw, and chaff branches off from the separating device 9; this stream has not yet been fed to either the grain tank 8 or the chopping device 10. This partial stream passes through a cleaning device 12, which is designed to extract the remaining grain and transfer it to the grain tank 8. The remaining partial stream, consisting primarily of short straw and chaff, is either fed to the crop distribution system 11 or deposited directly onto the field floor 14.

[0026] The chopping device 10 and the crop distribution arrangement 11 are arranged in the rear area of ​​the combine harvester 1 and serve to distribute already threshed crop 13 onto the field ground 14 in adjustable throwing directions 15. It should be taken into account that, depending on the design, the crop 13 can be thrown in numerous throwing directions 15. Here, and preferably, the distribution arrangement 11 has two distribution units 11a, 11b, which each cyclically throw the crop 13 over a predetermined throwing direction range 16a, 16b. Fig. 1 bis 5 Only one throwing direction 15 is shown as an example. From a summary of the Fig. 1 and 2 It is evident that the respective throwing direction 15 is composed of the vector components of a horizontal throwing direction 15h and a vertical throwing direction 15v.

[0027] It is now essential that the driver assistance system 2 is set up to optimize the control of the crop distribution arrangement 11 by means of at least one of the sub-strategies "throwing direction correction" and / or "inclination-dependent crop distribution" and / or "crop distribution in longitudinal direction" and / or "crop distribution in transverse direction" with regard to at least one optimization criterion.

[0028] The above sub-strategies are, in a sense, the method for fulfilling at least one of the optimization criteria mentioned above. An exemplary optimization criterion is preferably a high degree of uniformity in the crop distribution on the field surface 14, specifically in the transverse direction 17 of the combine harvester 1 and / or in the longitudinal direction 18 of the combine harvester. A uniform crop distribution on the field surface 14 promotes the advantageous decomposition of the crop 13 mentioned above. An exemplary crop distribution on the field surface 14 in the transverse direction is shown in the cross-sectional view according to [reference to figure]. Fig. 2 .

[0029] Alternatively or additionally, an optimization criterion may be provided that relates to the setting of a predetermined crop distribution on the field floor 14, in particular a predetermined crop distribution in the longitudinal direction 18 and / or in the transverse direction 17 of the combine harvester 1. Depending on the subsequent field processing, different predetermined crop distributions may be advantageous. A crop distribution in the longitudinal direction 18 of the combine harvester 1 is shown in the sectional view according to Fig. 3 exemplary.

[0030] Alternatively or additionally, it may be provided that an optimization criterion concerns the setting of the crop distribution E within the currently current driving lane F.

[0031] The preferred sub-strategy here, "throwing direction correction", results in an optimization of the throwing direction 15 of the harvested crop 13 by adjusting the horizontal throwing direction 15h and / or the vertical throwing direction 15v.

[0032] Adjusting the horizontal throwing direction 15h is particularly easy by means of adjustable spreading plates in the distribution units 11a, 11b, which are preferably designed as radial distributors. Reference is made here to the German patent application DE 10 2014 113 965 A1, which originates from the applicant and whose content is incorporated into the present application.

[0033] The vertical throwing direction 15v can be realized in a particularly simple way by making the distribution arrangement 11 as a whole or the distribution units 11a, 11b each pivotable about a pivot axis 19 which is aligned parallel to the transverse direction 17 of the combine harvester 1.

[0034] The sub-strategy "inclination-dependent crop distribution" preferably optimizes the control of the crop distribution arrangement 11 depending on the lateral inclination φq and / or the longitudinal inclination φl of the combine harvester 1 by adjusting the horizontal throwing direction 15h and / or the vertical throwing direction 15v and / or the throwing speed. The throwing speed can be implemented in a distribution unit 11a, 11b designed as a radial distributor by varying the speed of the blower accordingly. Reference may also be made in this respect to the aforementioned patent application DE 10 2014 113 965 A1.

[0035] Fig. 4 Figure 1 shows the situation in which a lateral tilt of an angle φq relative to the horizontal H exists. Due to the lateral tilt φq, the crop distribution would shift in the transverse direction 17 of the combine harvester 1 unless countermeasures are taken. Preferably, the throwing direction 15 of the distribution arrangement 11 is adjusted such that the crop distribution E always lies within the current driving lane F.

[0036] At the in Fig. 4 In the harvesting situation shown, the optimization of the control of the crop distribution arrangement 11 is therefore implemented by adjusting the horizontal throwing direction 15h. The resulting distribution of the harvested crop is in Fig. 4 shown in a dashed line.

[0037] Alternatively or additionally, it may occur that when passing over a crest, 20 according to Fig. 5a or by passing through a depression 21 according to Fig. 5b a longitudinal inclination φl results. In a particularly preferred embodiment, the sub-strategy "inclination-dependent crop distribution" optimizes the control of the crop distribution arrangement 11 as a function of the longitudinal inclination φl of the combine harvester 1 by adjusting the vertical throwing direction 15v. The result of the optimized control is shown by the throwing paths depicted in dashed lines. For example, the proposed solution readily achieves a uniform crop distribution in the longitudinal direction 18, as shown in the sectional view according to [reference]. Fig. 3 shown, although the combine harvester 1 reached the crest 20 according to Fig. 5a or the depression according to Fig. 5b passes through.

[0038] The sub-strategy "crop distribution in the longitudinal direction" optimizes the control of the crop distribution arrangement 11 with regard to the crop distribution in the longitudinal direction 18 of the combine harvester 1, at least by adjusting the vertical throwing direction 15v and / or the throwing speed. This sub-strategy can be applied regardless of whether the combine harvester 1 is tilted longitudinally or not.

[0039] The sub-strategy "longitudinal crop distribution" is also applied when combine harvester 1 stops, to ensure that no crop heaping occurs after the combine harvester 1 stops. Specifically, it is proposed here that the driver assistance system 2 detects when combine harvester 1 stops and, based on this, adjusts the longitudinal crop distribution E 18 of combine harvester 1 with regard to at least one optimization criterion.

[0040] In a particularly preferred embodiment, the driver assistance system 2 controls the crop distribution arrangement 11 in such a way that the crop distribution E on the field surface 14 does not result in any clumping of crop. This can be achieved, for example, by deflecting the vertical throwing direction 15v upwards and increasing the throwing speed while the vehicle is stopped, so that the excess crop is distributed over the already harvested field surface 14 and does not lead to the formation of clumps.

[0041] The sub-strategy "crop distribution in the longitudinal direction" also makes it possible to react to entering a headland. Specifically, it is proposed that the driver assistance system 2 detects the course of a headland and, based on this, adjusts the control of the crop distribution arrangement 11 with regard to at least one optimization criterion. In a particularly preferred embodiment, the driver assistance system 2 controls the crop distribution arrangement 11 in such a way that the headland is excluded from the crop distribution. This sub-strategy can also be advantageous when approaching a headland at an angle, so that, for example, the high uniformity of crop distribution mentioned above can be achieved even with such an angled approach.

[0042] Another preferred sub-strategy, "crop distribution in the transverse direction," optimizes the control of the crop distribution arrangement 11 with regard to crop distribution in the transverse direction 17 of the combine harvester 1, at least by adjusting the horizontal throwing direction 15h and / or the throwing speed. This allows, in particular, a uniform crop distribution in the transverse direction 17 of the combine harvester 1 to be achieved, as shown in the sectional view according to... Fig. 2 can be seen from this.

[0043] In the proposed sub-strategy "crop distribution in the lateral direction," a weather-related influencing factor, namely a possible crosswind, plays a special role. Such a crosswind can lead to a shift in the overall crop distribution E, which can be compensated for by the sub-strategy "crop distribution in the lateral direction." Preferably, the driver assistance system 2 detects a crosswind in the area of ​​the crop distribution arrangement 11 and controls the crop distribution arrangement 11 depending on the detected crosswind. Such a crosswind can be easily detected by a suitable wind sensor.

[0044] The sub-strategy "transverse distribution of material" is, in a further preferred embodiment, designed such that the driver assistance system 2 determines the condition of an adjacent lane N and, depending on the condition of the adjacent lane N, controls the material distribution arrangement 11. The determination may reveal that the adjacent lane N is actually a field boundary. The adjacent lane N is shown reduced in size in the drawing for clarity.

[0045] In a particularly preferred embodiment, the driver assistance system 2 excludes the adjacent lane N from the crop distribution E on the field if the condition of the adjacent lane N is that of an unharvested field or a field boundary. This ensures that no crop 13 is distributed into areas where such distribution would be disadvantageous.

[0046] The condition of the adjacent lane N can be determined, for example, using sensors such as a camera. Alternatively, existing mapping data stored in a database could be used.

[0047] If the condition of the adjacent lane N is that of a harvested stubble area, the distribution of harvested material can easily be extended to the adjacent lane N. For example, a defined overlap between lanes F and N can be provided so that the area between lanes F and N is also reliably covered with harvested material.

[0048] Another type of optimization involves the driver assistance system 2 identifying one of the existing edge 22 or the existing edges 22 and 23 assigned to the current lane F and maintaining a predetermined lateral distance to the existing edge 22 or edges 22 and 23. This is an alternative to the overlap between lanes F and N mentioned above.

[0049] In a further preferred embodiment, the driver assistance system 2 determines the course of an adjacent lane N, and the crop distribution arrangement 11 is controlled by the driver assistance system 2 depending on the determined course of the adjacent lane N. In a particularly preferred embodiment, the driver assistance system 2 controls the crop distribution arrangement 11 in such a way that the crop distributions E on the field surface 14 of two adjacent lanes F, N connect to one another.

[0050] As mentioned above, the combine harvester 1 is preferably equipped with a sensor arrangement 24 for detecting the crop distribution E on the current driving lane F and / or on adjacent driving lanes N, on the basis of which the driver assistance system 2 optimizes the control of the crop distribution arrangement 11. This sensor arrangement 24 can also be used to detect the Fig. 5 longitudinal slope φ l shown, which in Fig. 4 shown cross slope φq, which is in the Fig. 2 bis 4 The shown existing edges 22, 23 or the like can be used. The sensor arrangement 24 can include at least one laser proximity sensor, a camera, or the like.

[0051] The sub-strategies described above can be based, at least in part, on maintaining a predetermined distribution width E of the crop distribution in the transverse direction 17 of the combine harvester 1. Here, and preferably, the distribution width on the field surface 14 is adjustable by synchronizing the throwing direction range with the throwing speed range.

[0052] In Fig. 1 It is indicated that the driver assistance system 2 has a human-machine interface, here and preferably an input / output device 25, wherein operating parameters, here and preferably the at least one sub-strategy or related strategy parameters, can be entered by the user via the input / output device 25. This allows the proposed solution to be set with a high degree of user-friendliness.

[0053] For example, it may be provided that the cutting width of the grain cutting unit 3 can be entered via the input / output device 25, whereby the driver assistance system 2 controls the crop distribution arrangement 11 depending on the entered cutting width.

[0054] In general, it can also be provided that individual, operator-side distribution requests can be entered via the input / output device 25, whereby the driver assistance system 2 in turn controls the goods distribution arrangement 11 depending on these distribution requests.

[0055] The proposed solution can also be used for mapping the respective field. For this purpose, it is proposed that the driver assistance system 2 references the control of the distribution arrangement 11 and / or the crop distribution E on the field surface 14 with positional data and stores this as georeferenced harvesting process data in a machine-local database and / or in a remote database. This makes it possible to refer back to the crop distribution E in subsequent processing steps, for example, to estimate humus formation until the next processing.

[0056] As mentioned above, the distribution arrangement 11 can comprise a single distribution unit 11a. Here, and preferably, however, the distribution arrangement 11 has two distribution units 11a, 11b, wherein the two distribution units 11a, 11b are arranged on opposite sides with respect to the longitudinal direction 18 of the combine harvester 1, and wherein the two distribution units 11a, 11b can be controlled independently of each other by means of the driver assistance system 2. This provides the greatest possible flexibility with regard to the proposed sub-strategies. Bezugszeichenliste
