Description

Technical Field

[0001] This invention relates to an agricultural machine. The agricultural machine, particularly a seeder and / or soil tillage machine, comprises: at least one support frame and at least one, particularly multi-part, bearing assembly; the at least one support frame is associated with the machine and includes at least one housing portion such that at least one crossbeam is substantially transverse to the direction of travel of the machine; the crossbeam is arranged at the housing portion via the bearing assembly to be at least partially rotatable about its longitudinal axis; wherein the bearing assembly includes at least one housing element, particularly when viewed in the circumferential direction, the at least one housing element includes an outer side facing the housing portion and an inner side facing the crossbeam, wherein at least one compensator is arranged between the inner side and the crossbeam, and the crossbeam is rotatably fixed to the bearing assembly, particularly to the housing element, via the at least one compensator. Background Technology

[0002] Various types of towed, mounted, and / or self-propelled machines are known in the agricultural sector. Besides seeders suitable for distributing materials, particularly seeds and / or fertilizers, on arable land, agricultural machinery also includes soil tillers capable of cultivating and / or post-treating the topsoil of such arable land. Agricultural machinery also includes tillage units consisting of a seeder and a soil tiller, constructed to combine the distribution of seed material with the cultivation of arable land. For the purpose of distributing or treating arable land accordingly, such agricultural machinery includes at least one working tool suitable for this purpose and properly coupled to a support frame of the implement.

[0003] Depending on the machine's posture, particularly between the working posture and / or transport posture, and / or according to the required working or penetration depth, a general-purpose working tool can be at least partially positioned and / or moved to different heights. For this purpose, such a working tool, particularly when viewed transversely to the machine's direction of travel as a plurality of working tools, is arranged such that it is adjustable in height, position, and / or direction via at least one, particularly common, crossbeam coupled to the machine.

[0004] For example, EP3649841A1 describes a general-purpose machine. This machine includes at least one support frame associated with the machine and having at least one housing such that at least one crossbeam is substantially transverse to the machine's direction of travel. Furthermore, the machine includes at least one, particularly multi-part, bearing assembly through which the crossbeam is arranged at the housing to be at least partially rotatable about its longitudinal axis. The bearing assembly also includes a housing element, particularly when viewed in the circumferential direction, comprising an outer side facing the housing and an inner side facing the crossbeam. Moreover, at least one compensator is arranged between the inner side and the crossbeam, through which the crossbeam is rotatably fixed to the bearing assembly, particularly to the housing element.

[0005] The problem with this type of machine construction lies particularly in the way the support frame, especially the bearing assembly, is coupled to the crossbeam. In one embodiment variant, the compensator is connected to the crossbeam, particularly by a form-fit connection. This variant is particularly disadvantageous due to the associated and / or necessary clearance between the bearing assembly, especially the compensator, and the crossbeam. This results in particularly high, especially additional, loads on the bearing assembly and / or the crossbeam, especially under load variations and / or fluctuations; these loads, in turn, negatively impact the safe operation of the machine. In other embodiment variants, the compensator is connected to the crossbeam by a form-fit connection, particularly by welding; this other variant is disadvantageous due to the lack of adaptability, particularly to the axial position of the connection between the compensator and the crossbeam. Here, subsequent adjustments to the position of the crossbeam relative to the machine's support frame are either impossible or only possible with considerable effort. Summary of the Invention

[0006] Therefore, the object of the present invention is to design a machine that at least partially eliminates the described disadvantages. In particular, a particularly variable connection is achieved between the bearing assembly and the crossbeam, and this connection is particularly reliable during operation.

[0007] According to the present invention, this objective is achieved by configuring the housing element and the compensator such that, in the assembled state, the bearing assembly, particularly the housing element and / or the compensator, is fastened to the beam support, particularly by force engagement and / or by clamping connection.

[0008] Due to this measure, the bearing assembly, particularly the compensator, has virtually no clearance and can still be connected to the crossbeam in a reversible and / or non-destructive manner. Depending on the required and / or anticipated location along the rows of arable land, and / or the associated row-related operating tools, multiple operating tools are preferably arranged at the crossbeam, which can thus be repositioned relative to the housing in the axial direction and / or along its longitudinal axis. For this purpose, the compensator and the installed crossbeam can be separated from each other before or during operation and can slide relative to each other, particularly axially. Furthermore, while the position of the housing relative to the support frame and thus the position of the bearing assembly are fixedly defined, the crossbeam, and thus the operating tools, can continue to be easily adapted in terms of position, orientation, and / or direction relative to the support frame. This allows the crossbeam, and thus the operating tools, to be easily adapted to the conditions or needs of the arable land, meaning that a particularly high level of machine flexibility has been achieved.

[0009] The compensator is preferably arranged such that at least one of its sides directly abuts against the housing element, and at least one other side directly abuts against the crossbeam. The compensator is configured to compensate for size and / or shape tolerances between the crossbeam and the bearing assembly, particularly the housing element. Even when different crossbeams differ in size and / or shape, this allows for at least substantially reuse or retention of the bearing assembly by replacing the compensator. This embodiment is particularly low-cost and / or easy to assemble. Furthermore, the profile or shape on one side of the compensator at least substantially corresponds to the profile or shape of the housing element, while another profile or shape on the other side of the compensator at least substantially corresponds to the profile or shape of the crossbeam. This allows the housing and the crossbeam disposed thereon to differ in size and / or shape, as such differences are compensated for by the compensator.

[0010] In a preferred embodiment, the compensator and / or housing element is at least partially formed of a metallic material, particularly steel and / or advantageous alloys, such as copper alloys. Alternatively or additionally, the compensator and / or housing element can be at least partially formed of a plastic material, particularly a fiber-reinforced material. Furthermore, alternatively or additionally, combinations of different material pairs are conceivable, in which the compensator and housing element are at least partially formed of different materials.

[0011] In alternative or additional embodiments, the compensator can be formed as a single unit and / or formed of several compensators rigidly connected to each other. However, the compensator is particularly preferably constructed as multi-part, especially as two parts and / or shaped as a semi-shell, and the compensator is assembled only when installed at the crossbeam to form the entire compensator. Therefore, it is unnecessary to thread the compensator onto the crossbeam. Furthermore, the shell elements and the compensator are preferably configured to introduce, and / or implement, a radial force oriented at least substantially perpendicular to the longitudinal axis of the crossbeam during the installation process and / or during the installed state. The compensator is also preferably configured to at least partially transmit the forces and / or torques generated between the crossbeam and the receiving portion of the support frame.

[0012] In a preferred embodiment of the machine according to the invention, the housing element, particularly along its inner side, and the compensator, particularly along its outer contact surface, are at least partially conical. This configuration allows for the compensation of bearing devices, particularly the housing element and the compensator, with respect to shape, position, and / or size tolerances between them and the crossbeam in a particularly simple manner. In the installed state, at least one corresponding contact surface of the housing element, formed by the inner side, at least partially abuts against at least one associated contact surface of the compensator. The housing element and the compensator are preferably connected to each other in a form-fitting and / or force-fitting manner, particularly in a clamping connection, wherein circumferential force and / or torque can be transmitted between the inner side of the housing element and the contact surface of the compensator. The compensator is particularly preferably formed in a rotationally symmetric and / or conical manner, preferably having a conical and / or truncated conical shape, wherein the outer periphery of the compensator is formed, particularly the contact surface facing the housing element. Furthermore, the inner side of the housing element and the contact surface of the compensator are preferably configured to correspond to each other at least segmentally in terms of their shape and / or size, wherein both the inner side of the housing element and the contact surface of the compensator are configured circumferentially.

[0013] In other developments of the machine according to the invention, a particularly adjustable axial force can be generated within the bearing assembly, which at least substantially corresponds to the longitudinal axis of the crossbeam. The bearing assembly, particularly the housing element and / or the compensator, is configured to at least partially convert the axial force into a radial force oriented substantially perpendicular to the axial force. The bearing assembly, particularly the compensator, is fastened to the crossbeam according to the radial force. The greater the axial force introduced and / or set, the higher the radial force converted, and therefore the higher the compressive force used to fasten the compensator to the housing element and / or the crossbeam. Preferably, a first compressive surface is formed at the housing element, arranged opposite to a second compressive surface formed at the compensator, and particularly configured to face the second compressive surface, wherein the respective facing sides of the compressive surfaces are at least substantially perpendicular to the longitudinal axis of the crossbeam. The axial force is preferably manually initiated and / or set by the operator.

[0014] In another preferred embodiment of the machine according to the invention, the bearing assembly includes at least one tensioning device extending through the housing element and / or compensator, and includes at least one tensioning disc and at least one tensioning body, the at least one tensioning disc being arranged laterally from the outside on the housing element and / or compensator, wherein axial force can be generated and / or adjusted by the tensioning device. The tensioning device preferably includes at least one, particularly common, tensioning disc, particularly a tensioning body constructed as a nut, and particularly at least one elongated element constructed as a screw. When in the installed state, the elongated element is arranged to protrude through the housing element and compensator. The tensioning disc is preferably associated with several tensioning bodies and / or elongated elements. Furthermore, the tensioning disc is preferably arranged between the housing of the support frame and the housing element of the bearing assembly. Furthermore, the tensioning disc is preferably configured to fix and / or retain the bearing assembly, and thus, when viewed in the axial direction, fix and / or retain the crossbeam at the housing of the support frame. Particularly preferably, at least one first tensioning disc is arranged laterally from the outside on the housing element, and at least one second tensioning disc is arranged laterally from the outside on the compensator. The tensioning disc is therefore configured to absorb introduced and / or introduceable axial forces, and / or to transmit these axial forces to the respective extrusion surfaces, and thus to the housing elements and the compensator. The ability to introduce axial forces particularly uniformly onto the associated extrusion surfaces via at least one tensioning disc is especially advantageous for operational safety.

[0015] Furthermore, the machine according to the invention is preferred, wherein the compensator, particularly along the outer contact surface, includes at least one recess, particularly groove-shaped or stepped, and the housing element, particularly along the inner side, includes at least one protrusion associated with the recess, particularly in the form of a rib or step, wherein, particularly when viewed in the circumferential direction, the compensator and the housing element are connected to each other in a form-fit manner by the recess and the associated protrusion. Particularly preferably, the forces and / or torques introduced and / or generated between the housing element and the compensator are transmitted at least partially between the inner side of the housing element and the contact surface of the compensator, and between the recess and the associated protrusion. With such a form-fit configuration, particularly when the clamping connection embodied between the inner side and the contact surface is overloaded and / or overcome, the housing element and the compensator remain connected to each other in a rotationally fixed manner. Particularly preferably, a plurality of recesses are formed along the compensator, and a plurality of protrusions associated with each recess are formed along the housing element. In alternative or additional embodiments where the compensator is constructed as a multi-part structure and / or in the form of a semi-shell, the protrusions are arranged at least partially between two parts and / or segments of the compensator when viewed in the rotational and / or circumferential directions.

[0016] Furthermore, the compensator preferably includes at least one inner periphery that faces the crossbeam when viewed in the circumferential direction and abuts the crossbeam directly and at least in sections in the installed state.

[0017] In a preferred development of the machine according to the invention, at least one recess is formed along the inner periphery, wherein the inner periphery at least almost completely abuts the crossbeam outside the at least one recess. The compensator here includes at least one segment along its inner periphery and / or its inner contour, which abuts the outer contour of the crossbeam and / or directly abuts the crossbeam, while another segment formed along the recess is arranged not to contact the outer contour of the crossbeam. Preferably, the compensator includes several such recesses along its inner periphery or inner contour, which do not contact the crossbeam in the installed and / or assembled state. For crossbeams preferably constructed with multi-sided profiles, particularly square, at least one recess is preferably arranged between two preferably rounded corners of the crossbeam, particularly in the middle. Thus, compressive forces and / or torques are introduced and / or transmitted at least substantially via segments arranged in the regions of the respective corners of the crossbeam, and / or arranged adjacent to the respective corners of the crossbeam. This embodiment utilizes the knowledge that the corner regions of the crossbeam have greater stability or can withstand greater stress. This measure further improves operational safety in a particularly simple manner.

[0018] Furthermore, the crossbeam is preferably associated with at least one actuator to at least partially rotate and / or pivot the crossbeam. Preferably, the actuator can be operated remotely.

[0019] In other preferred embodiments of the machine according to the invention, the actuator can be coupled to the crossbeam via at least one bearing device, particularly via at least one lever device. Particularly preferably, the actuator and / or the lever device connected to the actuator are directly connected to the bearing device. Therefore, the force and / or torque for rotating and / or pivoting the crossbeam can be directly introduced and / or transmitted to the bearing device. On the other hand, the hinge points on the crossbeam known in the prior art for connecting the actuator are eliminated. This measure is particularly advantageous for adjusting the position, orientation, and / or direction of the crossbeam relative to the support frame and / or arable land. The actuator and / or lever device are also preferably connected to the housing element and / or the tensioning device, particularly to the tensioning disc. Attached Figure Description

[0027] Figure 7 Other embodiments of the housing element and compensator according to the present invention are shown. Detailed Implementation

[0028] Figure 1 An agricultural machine 10 is shown, exemplarily configured as a towed seeder. The machine 10 includes a central storage container 11 for storing dispensing materials, particularly seeds and / or fertilizer, and is capable of conveying the dispensing materials to a plurality of working tools 20 arranged adjacent to each other transversely to the direction of travel F via at least one pneumatic conveying system (not shown). The working tools 20 are shown in a low working posture and are configured, for example, as seeding plow assemblies. Each working tool includes at least one furrowing element 21, particularly a disc plow blade, and at least one depth guiding element 22, particularly a depth guiding roller and / or pressure roller. Alternatively or additionally, at least one device for closing the furrow can also be associated with the corresponding working tool 20. The machine 10 is configured to place dispensing materials as needed on arable agricultural land, particularly within furrows provided for this purpose, via the working tools 20.

[0029] It should now be clearly stated again that only an embodiment of machine 10 is shown as an example, and alternatively or additionally, embodiments of machine 10 may also include working tools 20 configured as soil reclamation tools, such as excavators. Furthermore, alternatively, machine 10 may also be configured as an agricultural soil reclamation machine.

[0030] able to Figure 2A closer view shows the coupling of the working tool 20 to the machine 10. Accordingly, the machine 10 includes a machine frame 12, to which a support frame 13 having a housing 130 is associated, specifically configured as a longitudinal beam. Here, the support frame 13 is exemplarily connected to the machine frame 12. Alternatively or additionally, the support frame 13 may also be part of and / or integrated into the machine frame 12. The support frame 13 is configured to accommodate at least one crossbeam 24 via the housing 130, which is at least substantially transverse to the direction of travel F. The machine 10 also includes at least one multi-part bearing assembly 30, which is particularly associated with the housing 130, through which the crossbeam 24 is arranged at the housing 130 to be rotatable about its longitudinal axis L. Each working tool 20 is hinged to the crossbeam 24 via a steering arm 23 and an overload protection member 230, respectively.

[0031] The crossbeam 24 is also associated with at least one actuator 40 configured to at least partially rotate and / or pivot the crossbeam 24 and thus the working tool 20. Therefore, the working tool 20 can be adjusted at least partially, particularly remotely, by the actuator 40 in terms of its height, position, and / or orientation relative to the support frame 13 and / or the arable land. For example, the working tool 20 can thus be moved in an adjustable manner between at least two different postures, particularly between a working posture and a transport posture, and / or moved to different penetration depths into the ground.

[0032] Figure 3 and Figure 4 The bearing assembly 30 is shown in an enlarged view. Therefore, the bearing assembly 30 includes at least one, particularly integral, housing element 31, which, when viewed specifically in the circumferential direction, includes an outer side 310 facing the receiving portion 130 and an inner side 311 facing the crossbeam 24. As an alternative to the illustrated embodiment, the housing element 31 can also be constructed as several portions on at least two half-shells. Compensators 32A, 32B, particularly multi-part and / or half-shell shaped compensators 32A, 32B, are also arranged between the inner side 311 of the housing element 31 and the crossbeam 24, through which the crossbeam 24 is rotatably fixed to the bearing assembly 30, particularly to the housing element 31.

[0033] The housing element 31 and the compensators 32A and 32B are configured such that, in the assembled state, the bearing assembly 30, particularly the housing element 31 and / or the compensators 32A and 32B, is fastened to the crossbeam 24, particularly by force engagement and / or by clamping connection.

[0034] To install the bearing assembly 30, the housing element 31 is fitted onto the crossbeam 24 and / or pushed along the crossbeam 24 until it reaches the receiving portion 130. Before or after the threaded connection and / or pushing process, the compensators 32A, 32B are inserted into the housing element 31.

[0035] In addition, if it is possible Figure 4 and Figure 5 As can be seen more clearly, the housing element 31, particularly along the inner side 311, and the compensators 32A, 32B, particularly along the outer contact surfaces 320A, 320B, are at least partially and / or segmentally formed into a conical shape. The inner side 331 of the housing element 31 and the contact surfaces 320A, 320B of the compensators 32A, 32B are configured to correspond to each other and are connected to each other in a force-fit manner, so that circumferential force and / or torque can be transmitted between the inner side 311 and the contact surfaces 320A, 320B.

[0036] To force-fit the housing element 31 and the compensators 32A, 32B together, and thereby fasten the bearing assembly 30 to the crossbeam 24, a particularly adjustable axial force can be generated within the bearing assembly 30, at least substantially corresponding to the longitudinal axis L of the crossbeam 24. This axial force is manually adjusted and / or introduced by a tensioning device 33 extending through the housing element 31 and / or the compensators 32A, 32B, and includes at least one tensioning disc 330 and at least one tensioning body 331, the at least one tensioning disc 330 being arranged laterally on the housing element 31 and / or the compensators 32A, 32B from the outside. The tensioning device 33 also includes an elongated element 332, which is exemplarily configured as a screw, and the tensioning body 331 is configured as a nut. The tensioning disc 330 is specifically configured as an integral unit and is associated with a plurality of tensioning bodies 331 and elongated elements 332. Alternatively, the tensioning disc 330 can also be constructed as a multi-part structure, wherein the parts of the tensioning disc 330 are connected and / or interconnectable to each other in a puzzle-like manner.

[0037] Furthermore, the housing element 31 and / or the compensators 32A, 32B are configured to at least partially convert the axial force into a radial force oriented substantially perpendicular to the axial force. Depending on the magnitude of the radial force, the bearing assembly 30, particularly the compensators 32A, 32B, is fastened to the crossbeam 24, and thus the bearing assembly 30, particularly the compensators 32A, 32B, is connected to the crossbeam 24 in a force-fit manner. It is true that the greater the axial force introduced and / or set, the higher the converted radial force, and therefore the higher the compressive force used to fasten the compensators 32A, 32B to the housing element 31 and / or the crossbeam 24. To introduce and / or transmit the axial force as uniformly and / or extensively as possible, a first compressive surface 312 is formed at the housing element 31, and a second compressive surface 322 is formed at the compensators 32A, 32B, arranged opposite to the first compressive surface 312. The respective facing sides of the extrusion surfaces 312 and 322 are arranged to be at least substantially perpendicular to the longitudinal axis L of the crossbeam 24, wherein the tensioning disc 330 is arranged to abut against the second extrusion surface 322 of the compensators 32A and 32B. The tensioning disc 330 is also configured to fix and / or hold the bearing assembly 30, and thus the crossbeam 24, at the receiving portion 130 of the support frame 13, at least in the axial direction.

[0038] If it is also possible Figure 4 As can be seen more clearly, the actuator 40 is coupled to the crossbeam 24 via at least one bearing assembly 30, and in particular via at least one lever assembly 41. For this purpose, the actuator 40 is directly connected to the bearing assembly 30 via the lever assembly 41, and in particular to the housing element 31 via the tensioning device 33. Thus, the crossbeam 24 can be coupled to the machine 10 without additional hinge points and / or receptacles, and therefore the crossbeam 24 can be attached with particular flexibility relative to the support frame 13 and / or arable land.

[0039] exist Figure 6As can be seen, with the tensioning disc 330 concealed, when viewed in the circumferential direction, the compensators 32A, 32B include at least one inner peripheral edge 321A, 321B facing the crossbeam 24. In the installed state, the inner peripheral edges 321A, 321B are arranged to at least segmentally abut against the crossbeam 24, particularly against the outer peripheral edge or outer contour of the crossbeam 24. At least one recess 323A, 323B is formed along the inner peripheral edges 321A, 321B, such that the inner peripheral edges 321A, 321B at least almost completely abut against the crossbeam 24 outside the at least one recess 323A, 323. The embodiment shown here exemplarily illustrates a plurality of recesses 323A, 323B formed along the inner peripheral edges 321A, 321B, wherein the recesses 323A, 323B are respectively arranged along the outer contour of the crossbeam 24, at least substantially centrally between two corners, the crossbeam 24 being exemplarily constructed as a square tube. The advantage of this embodiment is that the compressive force and / or torque are introduced and / or transmitted at least substantially via segments that can be introduced and / or transmitted to the bearing assembly 30, the segments being arranged in the regions of the respective corners of the crossbeam 24, and / or arranged adjacent to the respective corners of the crossbeam 24.

[0040] Figure 7 Other embodiments of the housing element 31 and compensator 32 according to the invention are shown. The compensators 32A, 32B, particularly along their outer contact surfaces 320A, 320B, include at least one recess 324A, 324B, particularly groove-shaped or stepped. Protrusions 314A, 314B associated with and / or corresponding to the recesses 324A, 324B, are formed on the housing element 31, particularly in the form of ribs or steps. The compensators 32A, 32B and the housing element 31 are connected to each other by abutting and / or engaging the corresponding recesses 324A, 324B and protrusions 314A, 314B in a form-fitting and / or force-transmitting manner. The recesses 324A, 324B and protrusions 314A, 314B are configured to at least partially transmit forces and / or torques that can be introduced into the bearing assembly 30, particularly when the force fit along the contact surfaces 320A, 320B and the inner side 311 is overloaded and / or overcome. In addition, such as Figure 7 As shown, additional protrusions 315 can be arranged, and these additional protrusions 315 are arranged in the installed state between the first and second compensator elements in the multi-part compensator 32A, 32B.

[0041] It goes without saying that the features mentioned in the above embodiments are not limited to these specific combinations, and are possible in any other combination. Furthermore, it goes without saying that the geometry shown in the figures is merely an example, and is possible in any other construction.
