An operating state is preferably a state of the machine 1 in which the machine 1 can be operated as intended and / or properly, especially to ensure its function and safety. The operating state is characterized, for example, by a resulting working width of the machine 1.

In other words, the working machine 1 is a working machine 1 that can be attached to a tractor. The tractor is preferably an agricultural tractor and is omitted from the figures for clarity. The tractor can, for example, be an agricultural tractor in the form of a wheeled tractor or a tracked tractor. Preferably, the tractor includes its own drive unit and provides, among other things, a (resulting) operating tractive force for pulling the working machine 1 in the direction of movement BR.In an alternative embodiment, the machine 1 can also be designed as an autonomously mobile (self-propelled) machine 1 with its own drive unit (so-called "self-propelled"). The soil B can be part of an agricultural area. The soil B can, for example, be stubble soil from a harvested grain field.

[0052] The machine 1 is a so-called combined machine 1, which is also referred to as an "agricultural machinery combination". The machine 1 is used for cultivating the soil B and / or for incorporating an agricultural product into the soil B and / or for transporting an agricultural product. The agricultural product can be, for example, seed, such as grain seed, and / or fertilizer, such as granular mineral fertilizer.

Furthermore, each tool carrier frame 111 and 112 is coupled to the main support frame 101 via at least one actuating element 131, 133; 132, 134, thus enabling adjustability. The at least one actuating element 131, 133; 132, 134 can, for example, be designed as a linear actuator in the form of a double-acting hydraulic cylinder, which is pivotally coupled to both the main support frame 101 and each of the tool carrier frames 111 and 112.

Furthermore, each tool carrier frame 121 and 122 is coupled to the main support frame 101 via at least one actuating element 135, 136, thus enabling adjustability. The at least one actuating element 135, 136 can, for example, be designed as a linear actuator in the form of a double-acting hydraulic cylinder, which is pivotally coupled to both the main support frame 101 and each of the tool carrier frames 121 and 122.

The majority of the compaction elements 401, 402, and 420 are arranged side by side and / or spaced apart from each other along the associated axis of rotation X400. The compaction elements 401, 402, and 420 are designed as knobby wheels or knobby tires, thus making the first post-processing tool assembly 400 a so-called tire-packer roller. The respective distance between adjacent compaction elements 401, 402, 420 can be essentially constant or varying at least section by section along the associated axis of rotation X400.

The second post-processing tool assembly 300 represents an additional and / or further separate post-processing tool assembly 300 to the first post-processing tool assembly 400 by which the machine 1 is characterized.

[0072] The second post-processing tool assembly 300, analogous to the first post-processing tool assembly 400, is designed in a roller-like form in its operating state. The second post-processing tool assembly 300 comprises a plurality of compaction elements, of which compaction elements 301, 302, and 321 are designated. In other words, the second post-processing tool assembly 300 comprises a total of twenty-one compaction elements 301, 302, and 321.

The compaction elements 301, 302, and 321 are designed as rings, thus making the second post-processing tool assembly 300 a so-called ring roller. The second post-processing tool assembly 300 can, for example, be designed as a so-called Cambridge roller.The rings 301, 302, 321 can preferably each be made of a metallic material and each be characterized by a U-shaped soil compaction profile in cross-section.

The support device 600 can, for example, also be used to adjust the working depth of the pre-machining tool device 200. The support device 600 is arranged in the direction of movement BR in front of the pre-machining tool device 200 and is thus positioned upstream of it.

[0078] It is understood that the working machine 1 comprises further devices, modules and / or elements which are omitted from the figures for the sake of clarity and / or are not described in detail herein, for example, conduit elements for the agricultural product, conduit elements for supplying the actuating actuators 131, ..., 136 with a working medium, sensor elements for detecting, preferably measuring, at least one operating parameter, conduit elements for an electrical signal communication device, etc.

[0079] The machine 1 may further comprise a control device for adjusting, preferably for regulating and / or controlling, the actuating elements 131, ..., 136, or be configured to be connected to such a control device. The control device, which is also referred to as a "control unit", may be implemented partly in hardware and partly in software and may be configured to process electrical / electronic signals. The electrical / electronic signals may be assigned to and / or represent at least one operating parameter.

[0080] For a further description of the present invention, reference is also made below to the illustrations in the further figures.

[0081] Fig. Figure 2 shows the working machine 1. Fig. 1 in a top view, where for clarity some facilities, modules and / or elements are only partially shown or hidden, for example the container facility 700.

[0082] The pre-machining tool assembly 200 is configured by its spaced-apart machining elements 201, 202, 203 and the rows formed by them in their respective directions to generate a plurality of machining zones BZ1G1, BZ20G1; BZ1G2, BZ2G2, BZ21G2 along the direction of movement BR. The machining zones BZ1G1, BZ20G1; BZ1G2, BZ2G2, BZ21G2 are formed as strips on the base B and / or are spaced apart from each other depending on a respective distance and / or a respective width of the machining elements 201, 202, 203. The machining zones BZ1G1, BZ20G1; BZ1G2, BZ2G2, BZ21G2 generated in the operating state of the machine 1 run essentially parallel to each other on the base B.

[0083] To create further improved soil conditions, preferably for the introduction of an agricultural commodity in the form of seed, the first post-processing tool device 400 is configured for re-compaction of a first group of the plurality of processing zones BZ1G1, BZ20G1 and the second post-processing tool device 300 is configured for re-compaction of a second group of the plurality of processing zones BZ1G2, BZ2G2, BZ21G2, wherein the processing zones BZ1G2, BZ2G2, BZ21G2 of the second group are arranged along the direction of movement BR adjacent to the processing zones BZ1G1, BZ20G1 of the first group and / or between the processing zones BZ1G1, BZ20G1 of the first group.

[0084] The machining elements 401, 402, 420; 301, 302, 321 of the first and second post-processing tooling devices 300, 400 are spaced apart from each other and / or coordinated and / or designed in a transverse direction to the direction of movement BR such that machining zones BZ1G2, BZ2G2, BZ21G2 of the second group, which cannot be or can hardly be back-compacted by the first post-processing tooling device 400, are back-compacted by the second post-processing tooling device 300, and machining zones BZ1G1, BZ20G1 of the first group, which cannot or can hardly be back-compacted by the second post-processing tooling device 300, are back-compacted by the first post-processing tooling device 400.

[0085] Preferably, the processing elements 301, 302, 321 of the second post-processing tool device 300 are each designed and / or arranged correspondingly to a position, preferably to an orientation, and / or to a respective dimension and / or to a respective distance of the processing elements 401, 402, 420 of the first post-processing tool device 400, such that in a view in the direction of movement BR, for example, there is no overlap of the processing elements 301, 302, 321; 401, 402, 420 of the first and second post-processing tool devices 300, 400, but the processed soil B experiences a substantially uniform recompaction over almost an entire working width.

[0086] In other words, by providing two packer rollers 300, 400, it is possible, with a corresponding weight distribution, to reconsolidate the soil B over almost the entire working width of the machine 1, thus ensuring, for example, that the soil B is not only reconsolidated in strips.

[0087] The second post-processing tooling device 300 comprises three tool modules (recompaction modules) 330, 331, 332, each with seven compaction elements 301, 302, 321, of which a first tool module 331 and a second tool module 332 are adjustably coupled to the tool carrier frames 111 and 112 on opposite sides.

[0088] The second post-processing tooling device 300 is arranged in the direction of movement BR between the first post-processing tooling device 400 and the pre-processing tooling device 200, so that the second post-processing tooling device 300 is arranged adjacent to the first post-processing tooling device 400 and upstream.

[0089] To illustrate this further, Fig. 3 an enlarged section of the representation of the working machine 1 in Fig. 2.

[0090] The second post-processing tool assembly 300, that is, the tool modules 330, 331, 332, are each coupled to the machine frame 100, that is, to the tool carrier frames 110, 111, 112, via at least one adjustable clamping element, of which the adjustable clamping elements 341, 342 are designated, in order to apply a defined preload force to the processed soil B by means of the compaction elements 301, 302, 321 when the second post-processing tool assembly 300 is set to a defined height. The at least one adjustable clamping element 341, 342 can, for example, comprise a preload spring and / or a threaded rod. The at least one adjustable clamping element 341, 342 can be configured to be manually operated by an operator of the machine 1.Alternatively, the at least one adjustable clamping element 341, 342 can be designed as an actuated positioning element which, for example, can be automatically adjusted depending on at least one operating parameter as disclosed herein. The automated adjustment of the at least one adjustable clamping element 341, 342 can be implemented using the control device as disclosed herein.

[0091] In Fig. 3 further shows the position of the actuable adjusting element 133, which is coupled on the one hand to the main support frame 101 and on the other hand to the tool carrier frame 111, in order to set a defined height of the pre-machining tool device 200 and the second post-machining tool device 300 to the ground B as a result of actuation.

[0092] As can be seen from the presentation in Fig. As can be seen from Figure 3, the respective diameter of the majority of compaction elements 301, 302, 321 of the second post-processing tooling device 300 is smaller than the respective diameter of the majority of compaction elements 401, 402, 420 of the first post-processing tooling device 400.

[0093] Furthermore, the respective width of the compaction elements 301, 302, 321 of the second post-processing tool device 300 is essentially equal to the respective distance between adjacent compaction elements 401, 402, 420 of the first post-processing tool device 400.

[0094] The compaction elements 301, 302, 321 of the second post-processing tool device 300 and the compaction elements 401, 402, 421 of the first post-processing tool device 400 can be designed relative to each other and / or arranged offset from each other in such a way as to re-compact a soil surface of the soil B over its entire area or at least in strips.

[0095] It is additionally or alternatively possible that the first post-processing tool assembly 400 and the second post-processing tool assembly 300 have different or essentially the same working widths and thus extensions in the respective directions of the associated rotary axes X300, X400. The adjustment of the at least one adjustable clamping element 341, 342 can be made depending on a working width of the first and / or second post-processing tool assembly 300, 400 in the operating state and can therefore vary.

[0096] Fig. Figure 4 shows an enlarged section of the representation of the working machine 1 in Fig. 1, where some facilities, modules and / or elements are hidden, primarily to highlight the arrangement and position of the second post-processing tooling unit 300 between the pre-processing tooling unit 200 and the first post-processing tooling unit 400.

[0097] Fig. Figure 5 shows the working machine 1 from Fig. 1 in a side view, where some facilities, modules and / or elements are only partially shown or hidden.

[0098] The operating weight force F_G is transferred to the ground B primarily via the force component F_G1 at the first finishing tool unit 400. A further force component F_G2 of the operating weight force F_G is transferred to the ground B via the second finishing tool unit 300, resulting in an improved weight distribution of the machine 1 on the ground B under operating conditions.

[0099] Adjusting the distribution of the operating weight force F_G on the first and second post-processing tool units 300 and 400 can be advantageous, for example, in difficult soil conditions such as soil B. For instance, in sandy, light soil B, a corresponding weight distribution can prevent or at least significantly reduce the sinking of the first post-processing tool unit 400, which acts as the main packer roller.

[0100] Fig. Figure 6 shows a section of a hydraulic circuit diagram of a hydraulic circuit, which can preferably be used for the actuating elements 131, 132, 133, 134, 135, 136 of the working machine 1. The schematically depicted actuating elements 131, 132, 133, 134, 135, 136 are preferably designed in the form of double-acting hydraulic cylinders. The hydraulic circuit also includes a limiting device 137 in the form of a centrally acting pressure relief valve. The hydraulic circuit is supplied with oil as the working medium via a power unit 138 in the form of a hydraulic pump.

[0101] It is understood that the hydraulic circuit includes further elements and / or devices that are in Fig.6 not shown, such as a safety device against overload in the form of a pressure accumulator, a valve device in the form of a throttle valve, an interruption device in the form of a shut-off valve to interrupt the hydraulic oil flow in order to keep the respective actuable actuator(s) 131, 132, 133, 134, 135, 136 in a corresponding actuated state and thus ultimately the pre-machining tool device 200, the first post-machining tool device 400, the second post-machining tool device 300 and / or at least one further device in a defined position, i.e. position and / or orientation, in order to achieve, among other things, an optimized distribution of the operating weight force F_G of the working machine 1 on the ground B.

[0102] The hydraulic circuit can be configured for control and / or regulation by a control device as disclosed herein.
