Description

Technical Field

[0001] The present invention relates to a plow module having a plow-following stabilization mechanism for replaceably mounting on a frame of a plowing device for plowing, and to a plowing device equipped with at least one such plow module. Background Art

[0002] When plowing with such a plowing device, which is usually towed by a tractor, a so-called moldboard is cut from the ground. The moldboard has a side region along which a first cutting element cuts or has cut. In addition, the moldboard has a bottom region that connects the two side regions and is separated from the ground by a second cutting element. Correspondingly, the ground has a separation surface in the bottom region of the moldboard (i.e., the so-called furrow bottom). An approximately rectangular moldboard is cut out from the ground, a horizontal cutting plane (= furrow bottom) is established by the second cutting element, and a vertical cutting plane (= furrow wall) is established on the remaining ground by the first cutting element. By cutting out the moldboard, a furrow wall is formed on the ground, and the side region of the moldboard detaches from the furrow wall. Thus, the bottom region defines the lowest surface in the vertical direction of the moldboard when it is separated from the ground.

[0003] It should be noted that the terms "horizontal" and "vertical" and "above" and "below" relate to the arrangement and construction of the plowing device and thus also of the plow module according to the invention fixed thereto, the plowing device being placed on the ground and being considered movable in the working direction during the plowing operation.

[0004] A related plowing device is known from DE102017102683A1. On the frame of this plowing device, a rotatable first cutting element designed as a cutting disk with a rotating first cutting edge is arranged, wherein the first cutting element is designed such that by moving the plowing device on the ground in the plowing direction, the side region of the moldboard of the ground can be cut out. The plowing direction or working direction is defined as the direction in which the plowing device travels on the ground. A flat second cutting element with a second cutting edge is also fixed to the frame and is arranged in front of the first cutting element in the plowing direction. The second cutting element is designed such that by moving the plow module on the ground in the plowing direction, the bottom region of the moldboard can be cut open. When plowing with such a plowing device, first the bottom region of the moldboard to be formed is cut by the second cutting element. Then, the first cutting element, designed as an arched cutting disk, cuts the side region of the moldboard and places it in the formed furrow in a flipped manner. Compared with a traditional plow having a plow body and a plowshare, this plowing device requires significantly less traction.

[0005] The disadvantage of the plowing device according to DE102017102683A1 is that the various cutting elements are individually assembled on the base frame, which makes it difficult to assemble or retrofit on a conventional base frame for a plow. In addition, the spatial alignment of the two cutting elements with respect to each other is complex, and the setting or adjustment of the two cutting elements can usually only be carried out within a very small range.

[0006] DE20304036U1 describes a device for processing hop crops. The device is configured to be articulated to a tractor and has a base frame, on which at least two working devices are fixed. The first working device is a grubbing device for levelling a plot of land to expose the vines of hop rhizomes in a plot of land, and the second working device in the form of a cutting device is provided for cutting the exposed vines of the hop rhizomes. A cantilever is provided on the base frame, and the respective working devices are fixed to the cantilever by respective linkages. The two working devices are arranged one behind the other and can process a plot of land in one operation to expose the vines and subsequently cut the vines. With this known device for processing hop crops, plowing cannot be carried out.

[0007] The working principle of the plow module according to the unpublished DE1020192042562 of the same applicant is that the cutting element from the furrow wall undercuts the turnover wall to be separated and turned over, and then turns over together with the hollow disc, and the overall effect is very good. However, this known plow has shown that the plow module does not achieve balanced following. This means that in actual use, a plow usually having a plurality of plow modules may also protrude laterally due to the non-uniformity of soil flow during plowing. The ground compaction and ground composition often vary greatly, resulting in significant changes in the cutting width and cutting depth of the first hollow disc at the front. This causes the lateral force in one direction to be greater than the lateral force in the opposite direction, so that the plow loses its guidance. This means that the plow has a tendency to "querzustellen", breaking through the so-called intermediate draft line. These forces acting on the plow and the plow module result in high loads on the bearings of the hollow discs.

[0008] Using the also known moldboard plow, better following control can be achieved because the actual plow body abuts against the furrow wall together with a relatively large plowing device, whereby stable following can be achieved, i.e., the plow travels along the intermediate draft line. However, when pulling the plow across the ground, this must be achieved with a significantly higher traction force. Summary of the Invention

[0009] The object of the present invention is to modify a plow of a known modular structural type in such a way that the lateral forces are balanced and the plow can maintain a straight course, i.e., maintain straight following, so that the overall stability of the plow following can be achieved.

[0010] This object is achieved by a plow module according to the invention and a plowing device according to the invention. Appropriate refinements are defined in the following description.

[0011] The above object is achieved for a plow module as a completed assembly structural unit and a plowing device having such a plow module in such a way that the second cutting element is designed as a fixedly arranged cutting knife and angled backward, i.e., angled opposite to the plowing direction, so as to achieve a dynamic force balance between the first cutting element and the cutting knife in a plowing direction-stable manner. The plow module generally includes a first carrier structure on which the first cutting element is arranged and a second carrier structure on which the second cutting element is arranged. The second carrier structure is connected to the first carrier structure, and the first carrier structure has means for detachably fixing to the frame of a plowing device having at least one plow module. In the plow module, the second cutting element is arranged behind the first cutting element in the plowing direction, and in addition to at least one, preferably two plow modules of the plowing device according to the invention, it also has a contact plate supported on the plow furrow wall, so as to support the plowing device as a whole and the corresponding plow module in a following-line-stable manner.

[0012] According to a first aspect of the invention, a plow module for a plowing device for plowing is introduced. The plow module has a first carrier structure on which a rotatable cutting element, such as an arched disk, is arranged. A second cutting element, such as a cutting knife arranged at a defined angle, is assembled on a second carrier structure, and the second carrier structure is in turn fixedly connected to the first carrier structure. The rotatable first cutting element has a first cutting edge that rotates around and is designed such that when the plowing device having the carrier structure moves on the ground along its plowing direction, i.e., the working direction, a side region of the turned soil wall that cuts out the ground from the plow furrow wall is cut by a first cutting area of the first cutting edge. The first carrier structure and the second carrier structure are fixedly connected to each other and are arranged together on the basic structure of the plowing device. The second cutting element has a second cutting edge, and the second cutting element is arranged on the second carrier structure and is designed such that when the plow module moves on the ground along the plowing direction, especially along the separation surface between the turned soil wall and the plow furrow bottom, a bottom region of the turned soil wall that cuts out the ground is cut by a second cutting area of the second cutting edge. The second cutting element is arranged relative to the first cutting element in the plowing direction such that the second cutting area is behind the first cutting area in the plowing direction.

[0013] Preferably, the respective cutting elements on the plow module can be adjusted, preferably pivotable, in terms of their positions relative to each other. This represents a significant advantage. For example, such a plow module can be used in which the first cutting element for side cutting of the turned soil wall is arranged in front of the second cutting element for bottom cutting of the turned soil wall.

[0014] Preferably, the ploughing device has a plurality of plough modules, for example three to six modules on the ploughing side, i.e., for one chassis, there are a total of 6 to 16 modules. Different from known ploughing devices, in this ploughing device, the first cutting element for cutting the side of the turned soil wall is arranged behind the second cutting element, and the second cutting element cuts the bottom of the turned soil wall or cuts out the furrow of the turned soil wall from it. Obviously, this known structure is chosen because the first cutting element, for example in cooperation with a guide plate or in a design of a hollow disc, is responsible for turning over the cut-out turned soil wall. For this purpose, the bottom of the furrow, i.e., the bottom side of the turned soil wall, must have been cut. Therefore, in the known device, the second cutting element is arranged in front of the first cutting element with respect to its effective cutting edge. With this arrangement, the first cutting element can turn over the turned soil wall immediately after cutting the side wall of the turned soil wall because the bottom of the furrow has been cut. In order for the first cutting element to reliably cut the side part, or in a curved configuration, also to prepare the turned soil wall for turning over and start turning it over, the drive or bearing or support of the first cutting element must of course be arranged on its back side. However, this in turn means that the second cutting element and the first cutting element must each have a separate carrier, and the second cutting element and the first cutting element are mounted on the frame through the carriers. This makes it rather difficult to adjust the two cutting elements relative to each other.

[0015] In contrast, in the present invention, the first cutting element for cutting the side of the turned soil wall is arranged in front of the second cutting element for cutting the bottom surface of the turned soil wall or the furrow. This is usually not considered because in a ploughing device, the first cutting element for cutting the side of the turned soil wall is first arranged in the traction direction, and the turning function cannot be performed in the ploughing device either, although the shape is designed as a hollow disc and is in principle set for turning over the turned soil wall. Because the bottom of the furrow has not been cut yet. This is exactly the advantage of the module according to the present invention, that is, only two cutting elements need to be provided without the need for a guide plate or a template. The advantage according to the present invention now also lies in that since the first cutting element has a drive or bearing or carrier structure on its back side and is arranged in front of the second cutting element (the second cutting element also has a carrier structure), the two carrier structures of the first cutting element and the second cutting element can be connected to each other to form a module, and this module can be mounted on the carrier frame of the ploughing device through a single suspension. The decisive advantage is that by disassembling the plough body and installing the corresponding module, a traditional ploughing device with a plough body can be easily retrofitted. Of course, the traditional chassis (also called the plough beam) can be equipped with the plough module according to the present invention at the factory at the same time.

[0016] Surprisingly, it has now been shown that with a plowing device having a guiding cutting element in the form of a hollow disk, it is possible to cut the side regions without first turning them over, since the bottom of the furrow has not yet been cut. This is only done by a second cutting element following behind. If several such modules are arranged one behind the other in the plowing device, it has been shown that in the second module behind the first module, seen in the plowing direction, the first cutting element not only cuts the side face existing there of the turned-over wall, but also the bottom furrow that has already been cut there by the first module. Thus, the desired function can be directly carried out by the second module, namely the first cutting element in the form of a hollow disk cuts the side face of the turned-over wall and can at the same time turn over the turned-over wall.

[0017] In terms of construction, one can benefit from the fact that the support or carrier structure of the first cutting element points backward towards the carrier structure of the second cutting element, so that the two cutting elements can be easily installed and connected to form a module. For example, if the plowing device has only one plow module, then in the first pass over the plowed field, only the first pass is a pass that cuts the side of the uncut turned-over wall, so that only a partial turnover occurs. However, in the second pass, the turned-over wall that has been cut from the side at this time is immediately completely turned over by the first cutting element, since the second cutting element has already cut the bottom of the furrow in this area, thus cutting the bottom side of the turned-over wall. This has a distinct advantage compared to traditional plowing devices. It is possible to easily replace or retrofit a traditional plowing device with a plow body with a plow module according to the invention. Due to the modularity, it is also possible to easily and quickly replace defective plow modules on the plowing device or other plow modules that are appropriately adjusted due to changed ground structures.

[0018] Due to the non-uniformity of soil flow, i.e., due to different ground compaction and ground composition, the plow may "deviate" laterally during actual use, so that the plow does not follow the ideal following line. Thus, in particular, the cutting width and cutting depth of the first hollow disk may change significantly, whereby the lateral forces are no longer balanced but act differently on both sides. Thereby, the plow loses its guidance and deviates in the direction of the greater lateral force. Then the plow is laterally offset to a certain extent and breaks through the just-drawn furrow, i.e., the middle towing line. This results in a higher load on the hollow disk bearings. According to the invention, the fixedly arranged cutting knife forming the second cutting element is angled backward, whereby a dynamic force balance can be achieved in a stable manner in the plowing direction between the first cutting element and the cutting knife. In the context of the cutting knife, the meaning of "fixedly arranged" is different from that of a rotating disk for cutting the bottom of the furrow, which is also known in the prior art. The angle by which the cutting knife is angled backward is adjustable and is fixedly arranged to a certain extent, but only within a range of a certain angle corresponding to the ground.

[0019] A contact plate is provided in cooperation with the cutting knife, which can be said to extend transversely to its longitudinal direction on the cutting knife. The contact plate is provided separately and is supported on the furrow wall. Therefore, the contact plate and the cutting knife act together in a way that supports and stabilizes the plowing direction, thereby forming a cutting knife - contact plate - guide - unit. Thus, after the side region of the furrow wall, i.e., the soil - turning wall, has been cut, the knife cuts the furrow bottom. The contact plate is supported on the side wall, i.e., the furrow wall, thereby providing lateral guidance. The cutting knife - contact plate - guide - unit (also called the contact plate - undercut knife unit) can be said to act as a wear shoe with a supporting function. This combination of the cutting knife and the contact plate located thereon enables the plowing device to achieve stable following, thereby preventing lateral deviation during plowing. For this purpose, it is necessary for the plowing device to provide at least one such contact plate - undercut knife unit in the plowing direction, preferably on the first plow module. Such a unit is preferably also arranged on the last plow module. Providing such a unit at the beginning and end of a plowing device with multiple plow modules is particularly advantageous for stabilizing plow following. In any case, it is not necessarily required to connect the introduced unit to each module. Of course, from the perspective of unification and standardization, it is conceivable and feasible that all modules are designed in the same way. This has significant advantages when the plow modules must be replaced, as different storage facilities for storing the plow modules to be repaired or replaced are not required. In addition, if such a unit is connected to each plow module, the required tractive force can be further reduced.

[0020] The contact plate mounted on the cutting knife can be designed to be adjustable in terms of its height, the angle relative to the plow - following line, and the bending angle relative to the cutting - knife surface according to the respective ground conditions. The adjustment can be carried out electrically, mechanically, or hydraulically.

[0021] If, in addition to the adjustability of the contact plate, both the first and second cutting elements can be adjusted in terms of their positions relative to each other, the plow module according to the invention is particularly advantageous. This also enables adjustability to the ground to be plowed and the adjustability of the two cutting elements to be adjusted relative to each other, either individually or together. The second cutting element is pivotable on the carrier structure on which the first cutting element is fixed, so as to guide the second cutting element to tilt slightly downward when cutting through the ground, in order to prevent the cutting element for undercutting the furrow bottom from moving outwards during plowing, while fixing the first cutting element in the ground. The first cutting element can be pivoted and displaced in multiple directions, i.e., the first cutting element has multiple degrees of freedom, in order to achieve the corresponding optimal plowing result when the two cutting elements cooperate with each other.

[0022] Providing multiple modules on a plowing device also has the following advantages, namely, with the device according to the invention, a larger width can be plowed in one pass. When plowing at the edge of the field to be plowed, the detachment-embedding-pivoting of the cutting elements is also advantageous, otherwise the width of the last pass would be too large and could cause, for example, the risk of ground separation of a piece of ground in the case where the plow module is furthest from the side, and this piece of ground may already be in an adjacent field. To avoid this, it can be avoided by the detachment-embedding-pivoting of the corresponding cutting elements.

[0023] The plow module according to the invention is connected to a tractor, such as a tractor, via the basic mechanism of the plowing device, and the tractor thus pulls the cutting elements across the ground in the plowing direction. The base frame can also be part of a load-bearing iron or a skid. With a plow module consisting of two cutting elements arranged on a combined carrier structure, namely a first cutting element for cutting the side of the turned soil wall and for turning and a second cutting element for cutting the bottom of the furrow, the skid can also be completely dispensed with. The carrier structure has metal beams and / or fiber composite elements. In addition, as will be described in detail below, the installed elements can be adjustably fixed to the carrier structure.

[0024] The plow beam or carrier frame formed by the first and second carrier structures thus provides a rigid but adjustable fixing structure for the cutting elements on the plow module and the contact plates on the second cutting element, as well as for additional components such as hinges or adjusting elements. In other words, the cutting elements are fixed to the corresponding first or second carrier structure in such a way that relative movement between the cutting elements is not possible during plowing. If the second cutting element is pressed into the ground during plowing due to the cutting of the turned soil wall, the first cutting element is simultaneously pressed into the ground by the pulling force. Preferably, the cutting elements and the contact plates can also be adjustable during plowing, which can be done, for example, electrically or hydraulically.

[0025] According to an exemplary embodiment, the first and / or second cutting elements are pivotally fixed to the corresponding carrier structure, for example, by hinges, such that the angle between the axis of rotation and the extension direction of the second cutting edge can be adjusted and fixed in the desired position. In another advantageous embodiment of the invention, the second carrier structure itself is pivotally connected to the first carrier structure by a hinge. Thereby, the angle of attack of the second cutting element relative to the plowing direction can be adjusted. The angle of attack generally makes the guided cutting edge point slightly downward towards the land.

[0026] The second cutting element designed as a cutter and the contact plate can be pivotally angled together with the attack angle of the cutter via a common pivot. Thus, the undercut of the soil-turning wall can be carried out such that the plow maintains the required depth, and the contact plate is adjustably adapted to different ground qualities in order to achieve a supporting effect on the furrow wall while achieving stable following of the plow. In addition, a perforated plate is provided, in which the height of the contact plate can also be adjusted together with the cutter on the corresponding module of the tillage device.

[0027] In another exemplary embodiment, the first cutting element and / or the second cutting element are also arranged pivotably and / or translatably on the respective carrier structure in order to adjust the attack angle and the position relative to each other. Thus, depending on the ground conditions and depending on the required processing depth, in addition to the attack angle of the second cutting element relative to the tillage direction, the cutting element position and / or the angle between them can also be adjusted.

[0028] The device such as the hinge described above is used to adjust the cutting element angle (attack angle of the cutter) and is capable of adjusting the cutting element - bend angle (vertical inclination of the hollow disc relative to the furrow wall of the ground) and the cutting element - direction angle (relative to the tillage direction, i.e., relative to the tractor travel direction). The cutting line of the cutting element between the first cutting edge and the furrow wall can be adjusted in height by an adjustable support. Thus, the vertical and / or horizontal distance between the first cutting element and the second cutting element can be variably adjusted. In other words, in another exemplary embodiment, the first cutting element and the second cutting element can be arranged relative to each other such that the first cutting area of the first cutting edge of the first cutting element is vertically spaced from the second cutting edge of the second cutting element. The cutting width or tillage width for one pass can be adjusted by adjustment in the horizontal direction.

[0029] In the design of the present invention, preferably, the first cutting area is formed in a first cutting plane, and the second cutting area is formed in a second cutting plane, and the included angle formed by the first cutting plane and the second cutting plane is from 30° to 135°, especially from 45° to 110°. A desired angle can be set for this purpose such that the two cutting elements are pivotally supported on the respective carrier structures. Of course, a pre-given fixed alignment of the two cutting planes is also within the scope of the present invention.

[0030] The first cutting edge extends in a first cutting plane, while the second cutting edge extends in a second cutting plane. The first cutting element and the second cutting element are fixed relative to each other on a carrier structure such that the first cutting plane and the second cutting plane have an angle (opening angle) of especially greater than or less than 90° with respect to each other. In other words, in another exemplary embodiment, the first cutting element can be arranged such that there is an angle of approximately 0° to approximately ±30° between the axis of rotation of the first cutting element and the rotational direction of the second cutting edge. In particular, the normal of the first cutting plane has a (directional) component that is parallel to the horizontal direction when the plowing device is intended to rest on the ground. The axis of rotation of the cutting element is especially parallel to the normal of the first cutting plane. In addition, the normal of the second cutting plane has another (directional) component that is parallel to the vertical direction when the plowing device is intended to rest on the ground. For example, the angle between the normals can be selected between 45° and 130° in order to achieve a desired furrow pattern on the ground.

[0031] If the first cutting plane and the second cutting plane are especially at approximately 90° to each other, the second cutting element presses the undercut turning wall in the direction of the first cutting element. Thereby, during movement in the plowing direction, the turning wall can advantageously be processed between the first cutting element and the second cutting element. Through the interaction of the rotating first cutting element and the fixedly angled second cutting element, a preferred plowing result or "breaking" (soil breaking) is provided. In addition, the strong lateral pulling force of the first cutting element, which has a negative impact on the tractor's drawbar, is largely compensated by the reaction of the second cutting element. Thus, a balance between the lateral forces is achieved. The tractor thus remains on track without major counter-steering, i.e., the plowing device remains following stably while the traction force decreases.

[0032] The first cutting element is rotatably or pivotably fixed to a first carrier structure. Accordingly, the first cutting element has a first axis of rotation about which the first cutting element rotates. The first cutting element is preferably designed as an arched cutting disc and has a circular circumference line. The rotating first cutting edge is formed along the circumference line. By means of the first cutting edge, the side region of the turning wall is separated from the furrow wall of the ground while laterally turning the turning wall. The rotating first cutting edge has a first cutting region. The first cutting region is a circumferential segment of the first cutting edge that preferably first contacts and cuts the ground in the plowing direction. The first cutting element can have a diameter of approximately 500 mm to approximately 800 mm. In addition, the first cutting element can have teeth, be centrally supported and can preferably be adjusted in position relative to the first carrier structure and the second cutting element by means of a slide.

[0033] Particularly advantageously, the first cutting element rotatable about a rotational axis is arched or has a conical or frustoconical shape. This ensures that the cut-overturning wall is rotated and deposited in an adjacent furrow formed during the previous passage of the plow module. At this time, the rotational axis of the first cutting element is arranged at an angle to the plowing direction such that the leading edge of the cutting element forms an angle with respect to the plowing direction, and the cutting element extends substantially obliquely to the plowing direction and thus extends onto the overturning wall to be cut by the cutting element. The hollow disk has an inclination with respect to the pulling direction and the perpendicular to the furrow, i.e., it is inclined in the furrow direction and the pulling direction. The inclination of the pulling direction (also called the cutting angle) is preferably 10 to 30°. The inclination with respect to the perpendicular to the furrow is preferably 10° to 35°.

[0034] When the plowing device moves along the ground, the first cutting element rotates autonomously. Here, the frictional force causes the first cutting element to move. It is preferably dimensioned such that during plowing, only the lower half of the first cutting element located below the first rotational axis penetrates the ground, so that the frictional force with the ground can cause rotation.

[0035] The rotation of the arched or plate-shaped first cutting element also has the effect of lifting and simultaneously guiding the cut-overturning wall to the side. In particular, the cut-overturning wall is in frictional contact with the first cutting surface of the first cutting element. The first cutting surface is the surface formed within the first cutting edge of the first cutting element. In addition, the first cutting surface is the surface facing the cut-overturning wall. The first cutting surface can be formed uniformly without recesses or protrusions. In addition, the first cutting surface (i.e., the shell surface of the first cutting element) can be formed in a conical or frustoconical shape.

[0036] According to the invention, the second cutting element is designed as a cutting knife and is adjustably supported with respect to its attack angle. The second cutting edge is defined by a fixedly arranged edge of the second cutting element. The adjustable cutting knife of the second cutting element has a cutting edge extending transversely to the plowing direction. The cutting element preferably serrated on its cutting edge preferably points slightly backward at a defined angle with respect to the plowing direction, i.e., the included angle with the plowing direction is greater than 90°. With the second cutting edge, the bottom region of the overturning wall is separated from the bottom of the furrow on the ground, undercut and, if necessary, simultaneously lifted. The second cutting region is formed by the cutting knife as the second cutting edge, which then contacts and cuts the ground in the plowing direction.

[0037] The first cutting element, for example, an arched disk, cuts the overturning wall starting from the ground surface in a first vertical plane, for example, at a working depth of approximately 15 to 35 cm, and guides the overturning wall in the previously formed furrow.

[0038] In a second horizontal layer at a working depth of approximately 15 to 35 cm from the ground surface, the turnover wall is cut horizontally, i.e., starting from the bottom of the furrow, by a second cutting element, namely a cutting knife. The dynamic balance force between the two cutting elements acts in a plow-following stable manner.

[0039] The distance between the two cutting planes (upper: the rotating vertical first cutting element; lower: the horizontal second cutting element designed as a cutting knife) can be adjusted by adjusting the rotating cutting element.

[0040] The effective plow body composed of the main components of the arched first cutting element and the flat second cutting element in the form of a cutting knife roughly corresponds to an inclined turned-over plane pulled through the ground. The cut turnover wall is pushed upward and laterally on the inner side along the arched first cutting element. This process includes compressing the upper half of the turnover wall and stretching the lower half. As a result, compressive stress, tensile stress, and rotational stress are generated inside the turnover wall, which, in addition to the downward movement of the turnover wall due to gravity, also causes the ground to break up.

[0041] By arranging the second cutting element behind the first cutting element in the plowing direction according to the present invention, the frictional force that would cause a high required traction force for the plowing device can be reduced. Since the turnover wall has been separated from the bottom of the furrow in an undercut manner by the second cutting element when it is cut by the first cutting element on its side, the turnover wall has been lifted and flipped by the first cutting element. The second cutting area is in the plowing direction, for example, between 1 cm and 50 cm, especially between 15 cm and 25 cm, behind the first cutting area. Then, the cutting knife representing the basic level of the second cutting element contacts the ground and can be said to follow or trail the basically vertically arranged first cutting disc or cutting element. This arrangement of the second cutting element "cuts from below" the furrow wall or the turnover wall to be plowed horizontally, thus significantly facilitating splitting / furrow cleaning. The vertically arranged arched first cutting element cuts the horizontally pre-cut turnover wall by the downstream second cutting element during the subsequent pulling process, while flipping it and placing it laterally, preferably in the furrow, through the rotational movement of the hollow disc.

[0042] Therefore, the plowing device can achieve a smooth plowing effect while having following stability. Compared with traditional rigid plow bodies, the coefficient of friction is significantly reduced because the first cutting element rotates together. By this principle, an easy-to-pull, fuel-saving plow is provided, which at the same time produces an almost constant furrow pattern for seedbed formation, and the traction force is additionally reduced by the dynamic compensation of lateral forces.

[0043] The attack angle of the second cutting element can be optimally adjusted by an electrical, mechanical, or hydraulic adjustment device to adapt to changing ground conditions, preferably also during plowing.

[0044] According to another exemplary embodiment, the first or second cutting edge of the first or second cutting element is designed to be arched and toothed. The arched design means that the first or second cutting edge is constructed in an arched shape. The toothed design means that indentations or protrusions (teeth) are formed on the cutting edge. Thus, when cutting the soil-turning wall, an improved cutting effect of the first cutting element or the second cutting element can be achieved. With the spherical crown-shaped design of the first cutting element in particular, the soil-turning wall sliding along it can be turned over, so that the installation of formwork or guide plates can be dispensed with. The design of the first cutting edge of the first cutting element and / or the second cutting edge of the second cutting element having recesses on the circumference results in a design in the form of a circular saw blade, which can penetrate the ground particularly easily. The hollow disc cutting disc can be rotated by being embedded in the ground.

[0045] With the plowing device introduced, the saving of traction / fuel is made possible by its easy tractability. In addition, the plowing device can be universal and is suitable for almost all ground conditions. In addition, the soil-turning wall is continuously broken by the rotational movement of the cutting disc. This achieves the required soil fragmentation (soil clods). The soil clod effect can reduce the post-treatment process. This saves the working process up to the seedbed treatment. In addition, the soil is advantageously mixed. In addition, traditional standard components or standard additional tools, such as fertilizer applicators and disc plow blades, are no longer required. The rotating first cutting element reduces wear, thus reducing the spare part cost. Due to this fine plowing of the ground, compared with a plowing device with a traditional plowshare, the humus-destructive metal wear caused by the cutting element is largely avoided or reduced.

[0046] According to another exemplary embodiment, the plowing device has at least one additional plowing module, which also has a rotatable first cutting element having a circumferential additional first cutting edge, and the plowing device is designed such that when the carrier structure moves on the ground in the plowing direction, another side region of another soil-turning wall can be cut from the ground by another plowing module, and the other first cutting element is rotatable, so that another soil-turning wall can be lifted by the other first cutting element.

[0047] It is clearly shown by the above embodiments that a large number of plowing modules can be arranged adjacent to each other in the plowing direction, i.e., in a direction (in the horizontal plane) orthogonal to the plowing direction, and arranged adjacent and spaced apart. In this way, a large number of soil-turning walls arranged adjacent in the plowing direction can be cut out, lifted from the ground, and turned over if necessary.

[0048] When a large number or multiple corresponding plow modules and a corresponding number of cutting elements are arranged before and after in the plowing direction, due to the lateral offset of each plow module from each other transversely to the plowing direction, a wider area can be plowed in one pull compared to the case of using only a single plow module in one pull. Similarly, when the cutting elements are disengaged from the embedding and thus can pivot out of their set positions, it is beneficial for the function of the plowing device. For example, this enables the conversion of the following cutting elements into the cutting elements running in front. This is useful or advantageous for different parameters (such as ground conditions in the sense of optimal adjustment) in the combination of multiple plow modules of the plowing device.

[0049] Due to the angle adjustability of the cutting knife as the second cutting element, a dynamic force balance of the lateral forces between the hollow disk and the cutting knife is achieved, enabling stable plow following. It goes without saying that the more plow modules are combined on the carrier to form a plowing device, the higher the traction force generally required for the plowing device composed of multiple plow modules. Without a plowing direction stabilization mechanism, the lateral acting forces that cause the plowing device to deviate laterally from the straight towing line will be greater than the case where only a single plow module exists. More importantly, plow following stability is provided by appropriately adjusting or regulating the cutting knife, which also has a supporting effect on stabilizing the plowing direction by providing a contact plate. It has been shown that the additional contact plate together with the adjustability of the cutting knife for achieving the dynamic force balance angle of the lateral forces of the first cutting element in the form of a hollow disk and the second cutting element in the form of a cutting knife achieves plow following stability, where in the case of multiple plow modules on the plowing device, such elements in the form of contact plates and the angle - adjustable element cutting knife have been provided for the first and the last plow modules in the towing direction. This represents a compromise between low traction force and the forces that cause the plowing device to deviate from the ideal towing line. Of course, a higher construction cost is reasonable, and it is acceptable to provide contact plates and cutting knife adjustability for all plow modules.

[0050] When using the plowing device according to the present invention, for example, using the first cutting element in the form of an upper - rotatable arch, even without a guide plate and a template, the soil - turning wall of the ground can be turned over gently and flatly by a maximum of, for example, 15 cm. However, the adjustability of the additional contact plate and the attack angle of the cutting knife is required to achieve plowing direction stability.

[0051] In an exemplary embodiment, the first cutting element and the second cutting element are arranged on respective carrier structures in a replaceable manner (e.g., by means of a screw connection). The first carrier structure is designed to be assembled to the chassis of the plowing device in a detachable manner, which is preferably accomplished by means of a screw connection. To protect against stones, shear bolts, rubber packs or spring elements can also be provided. The assembly elements provided for this purpose (e.g., holes or pins) are preferably designed and arranged such that they are compatible with commercially available chassis for plowing devices. Thus, the plow module can be easily retrofitted on the chassis of the plowing device, rather than, for example, on the plow body.

[0052] Due to the rotation of the first cutting element, the separated soil-turning wall is slightly lifted, flipped and discharged onto the furrow. When the plowing device is moved in the plowing direction, the soil-turning wall is flipped in the plowing direction.

[0053] Since the soil-turning wall is lifted by the rotating first cutting element, the soil-turning wall can be placed behind the cutting element in an energy-saving manner in the plowing direction.

[0054] In the plow module according to the invention, the second cutting element is designed as a fixedly arranged cutting knife. In this case, the cutting knife is designed as a flat rectangular, straight or curved knife, which is fixed to the second carrier structure in one end region. This fixation is preferably accomplished by tightening, which also enables easy replacement of the second cutting element in case of wear. The cutting edge of the knife points in the plowing direction in its working position and is generally oriented transversely to this direction.

[0055] In an advantageous modification of this structure, the cutting knife of the second cutting element is configured in an L-shape, with the first beam of the cutting knife being horizontally oriented in the working position of the plow module and the second beam being oriented substantially perpendicular thereto. Thus, the first beam intersects the bottom region of the soil-turning wall to be formed. When the plow module is in the working position, the vertical second beam is located in front of the first cutting element and facilitates its entry into the ground, since the second beam is substantially in the same plane as the leading edge of the first cutting element. For reasons of mechanical robustness only, it is advantageous to design the cutting knife as an integral unit. The cutting knife is generally in the form of a flat knife with a sharp cutting edge on the front side. The angle of attack of the knife relative to the plowing direction is adjustable to ensure that the required depth of entry of the plow module into the ground is achieved and maintained. Together with the contact plate supported on the furrow wall, plow following stability is achieved.

[0056] The present invention further includes a plowing device, on the base frame of which there is provided at least one plow module according to the present invention, preferably 6 to 16 such plow modules are provided. In this case, the plow module is preferably fixedly connected to the base frame by means of screw connectors, wherein the connection is carried out by means of a first carrier structure. It goes without saying that compatible fixing elements, such as holes or bolts, must be formed on the base frame and the first carrier structure. Alternatively, adapter elements can also be provided so that the plow module can be adapted and fixed to different base frames of the plowing device. The corresponding plow module can thus be easily assembled on the base frame or removed, for example, for maintenance purposes. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] Figure 1Fig. 0 shows a plow module 1 for plowing a ground surface 120, wherein a first cutting element 102 in the form of a spherical-crowned hollow disk is arranged in a front-to-back manner in the plowing direction 110 in front of a second cutting element 105 in the form of a cutting knife 6. The first cutting element 102 is configured to cut the side surface of a turnover wall (not shown), while the second cutting element 105 arranged behind the first cutting element 102 is designed as a cutting knife 6 for cutting the bottom of a furrow. The first cutting element 102 and the second cutting element 105 are connected together as a plow module by a first carrier structure 4 and a second carrier structure 5. The first carrier structure 4 and the second carrier structure 5 can be fixed to a frame (not shown), and the second cutting element 105 is hingedly connected to the first cutting element 102 by the first carrier structure 4.

[0065] As Figure 1 shown, a rotatable first cutting element 102 having a rotating arched first cutting edge 103 is arranged on the first carrier structure 4 and is configured such that when the first carrier structure 4 moves on the ground surface 120 in the plowing direction 110, a side region 122 of a turnover wall (not shown) of the ground surface 120 can be cut by a first cutting region of the first cutting edge 103, as Figure 1 shown. The plowing direction 110 is defined as the direction in which a plowing device 3 moves above the ground surface 120. A second cutting element 105 having a second cutting edge 106 is arranged on the second carrier structure 5, and the second carrier structure is detachably connected to the first carrier structure 4 and can pivot relative to the first carrier structure 4 in relation to an attack angle. The second cutting element 105 is configured such that when the second carrier structure 5 moves on the ground surface 120 in the plowing direction 110, a bottom region of the turnover wall of the ground surface 120 can be cut by a second cutting region of the second cutting edge 106. The second cutting element 105 is arranged relative to the first cutting element 102 in the plowing direction 110 such that the second cutting region is arranged behind the first cutting region in the plowing direction 110. The second cutting region is thus spaced apart from the first cutting region by a distance x.

[0066] During plowing, since the base frame 2 of the plow module 1 having the first carrier structure 4 and the second carrier structure 5 is pressed in the direction of the separation surface 121 of the ground surface 120 or the bottom of the furrow, accordingly the first cutting element 102 is also pressed in the direction of the separation surface 121. This causes the first cutting element 102 to remain at a desired ground depth during plowing.

[0067] Figure 2 Fig. 14 shows a schematic view of basic functional elements of a plowing device according to an exemplary embodiment of the present invention. The Figure 2 figure shows the correct spatial arrangement of the first cutting element 102 and the second cutting element 105 and the formation and turning of the turnover wall. For the sake of clarity, the remaining components of the associated plowing device 3 are not shown.

[0068] Figure 2 The plowing device 3 shown in the figure has a base frame 2 or a plow beam of a conventional design, and plow modules 1 are appropriately mounted and extend from the base frame or the plow beam to both sides. According to the present invention, each plow module 1 has a first cutting element 102 designed as a hollow disk and a corresponding second cutting element 105 designed as a cutting knife 6. A contact plate 8 is additionally mounted on the second cutting element and is designed in the manner of a wear shoe. According to Figure 2 the illustration, the plow module 1 with the contact plate 8 is shown from its back side, which means that the cutting knife 6 ( Figure 2 not shown in the figure) extends from the back side of the contact plate 8. A first carrier structure 4 is shown, which provides the possibility of abutting the cutting knife 6 against the contact plate 8 through a hinge 7. The contact plate 8 can be said to be located in the upward-facing plane of the cutting knife 6, which is for the adjustability of the attack angle of the cutting knife 6 under different plowing conditions and ground conditions. Each module of the plowing device 3 consists of a first cutting element 102 designed as a hollow slider and a cutting knife 6 with a contact plate 8. The cutting knife is indirectly connected to the base frame 2, which is also called the plow beam, through the first carrier structure 4. The function of the contact plate 8 is to contribute to the dynamic force balance of the lateral force and is supported on the plow groove wall forming the side area of the plow groove (not shown). Thereby, the following stability of the plowing device 3 can be achieved. The plow achieves following stability due to the lateral force generated by the first cutting element 102 designed as a hollow disk when cutting the ground 120 and the subsequent turning of the soil-turning wall through the hollow of the disk. Without this lateral force of the contact plate 8, the plowing device 3 would tend to deviate from its straight following line; thus, following stability could not be achieved.

[0069] In Figure 3 the figure, two plow modules arranged front to back according to the present invention and slightly enlarged compared to Figure 2 are shown. Among them, the first cutting element 102 is designed as an arched concave disk with a first cutting edge 103, and the recess provided in the cutting edge can be said to be designed in a toothed shape. The first carrier structure 4 is shown on the convex back side of the hollow disk, and the cutting knife 6 is shown at the lower end of the first carrier structure. The attack angle of the cutting knife 6 can be adjusted so as to apply a force in the direction towards the ground 120 or the bottom of the plow groove (not shown). Thereby, the entire plow module 1 and further the plowing device 3 are maintained at the required plowing depth.

[0070] As Figure 1As shown, a first carrier structure 4 and a second carrier structure 5 for a first cutting element 102 and a second cutting element 105 are designed such that at least the first cutting element 102 and the second cutting element 105 are fixedly connected to a base frame 2 of a plowing device 3. The first carrier structure 4 can be fixed to a tractor, such as a tractor, via the base frame 2 of the plowing device 3, so as to drive the first cutting element 102 and the second cutting element 105 along the plowing direction 110 accordingly. The plow module 1, for example, has a first carrier structure 4 and a second carrier structure 5, and the first carrier structure and the second carrier structure can be designed to be fixedly or pivotally connected via a hinge.

[0071] The first carrier structure 4 and the second carrier structure 5 thus form a rigid fixing structure for the first cutting element 102 and the second cutting element 105. The first cutting element 102 and the second cutting element 105 are fixed to the first carrier structure 4 or the second carrier structure 5 such that there is no relative movement between the positions of the first cutting element 102 and the second cutting element 105 during plowing. If, according to the present invention, the second cutting element 105 is pressed in the direction of the ground 120 due to the cutting of the turnover wall, the first cutting element 102 is also simultaneously pressed into the ground 120 because the two carrier structures, namely the first carrier structure 4 and the second carrier structure 5, are fixedly connected to each other.

[0072] The first cutting element 102 is rotatable, while the second cutting element 105 is pivotable, or its attack angle is fixed to the corresponding first carrier structure 4 or second carrier structure 5. Accordingly, the first cutting element 102 has a rotation axis about which the first cutting element 102 rotates. The second cutting element 105 forms a pivot via a hinge 7 about which the second cutting element 105 can pivot with its attack angle. The first cutting element 102 is designed, for example, as a spherical crown-shaped cutting disc and has a circular circumferential line. A corresponding circumferential first cutting edge 103 with recesses 10 is formed along the circumferential line. The side region 122 of the turnover wall (see Figure 1 ) is separated from the furrow wall of the ground 120 by the first cutting edge 103. The circumferential first cutting edge 103 has a first cutting region which is the circumferential segment of the first cutting edge 103 that first contacts and cuts the ground 120 in the plowing direction 110. The bottom region 121 of the turnover wall is separated from the ground 120 by a cutting knife 6 serving as the second cutting element 105. The second cutting region of the second cutting edge 106 is the circumferential segment where the second cutting element 105 contacts the ground 120 for the second time or follows the first cutting element 102 and cuts the ground in the plowing direction 110. Figure 5The double arrow 12 in a indicates that the second cutting element 105 is pivotally mounted on a second carrier structure 5 (not shown here). This pivoting allows the adjustment of the attack angle of the cutting knife 6 relative to the tillage direction 110, thereby adjusting the depth to which the plow module 1 is embedded in the ground 120.

[0073] A rotatable disk-shaped hexagonal body (not shown) can be arranged in front of or connected to the plow module 1, which pre-cuts or separates the ground 120 using the cutting knife 6 and the first cutting element 102. This reduces the pulling force required for tillage and also reduces the wear of the cutting knife 6 and the subsequent first cutting element 102. The cutting knife 6 cuts horizontally and vertically as a double-edge or triple-edge and cooperates with the contact plate 8 in a stable following manner.

[0074] When the tillage device 3 moves along the ground 120, the first cutting element 102 rotates. Here, for example, friction causes the first cutting element 102 to move. The first cutting element 102 is dimensioned such that during tillage, only the lower half of the first cutting element 102 located below its axis of rotation penetrates the ground 120, so that the friction with the ground 120 causes rotation. The rotation of the first cutting element 102 also causes the cut soil turning wall to be lifted.

[0075] The cut soil turning wall is in frictional contact with the cutting surface of the first cutting element 102. The cutting surface is the surface of the first cutting element 102 formed within and surrounded by the first cutting edge 103. In addition, the cutting surface is the surface pointing to the cut soil turning wall. As Figure 1 and Figure 3 shown, the cutting surface can be designed to be uniform, without recesses or protrusions.

[0076] Due to the lifting of the soil turning wall by the rotating first cutting element 102, the soil turning wall can be conveyed to the adjacent furrow in an energy-saving manner. The furrow was dug during the previous pass of the plow module.

[0077] According to Figure 1 , the first cutting element 102 and the second cutting element 105 are fixed relative to each other on the first carrier structure 4 and the second carrier structure 5 such that when the tillage device 3 is placed on the ground 120 in the working position or penetrates the ground, the first cutting area of the first cutting element 102 is spaced apart from the second cutting element 105 in the vertical direction or is located above the second cutting element 105.

[0078] The rotating first cutting element 102 and the second cutting element 105 cooperate. On the one hand, the desired plowing depth is kept constant by the second cutting element 105, since the cut soil-turning wall presses against the second cutting element 105 with a defined pressure / tensile force at a set attack angle and thus counteracts the lifting of the rotating first cutting element 102. On the other hand, the energy beneficial effect of the rotating first cutting element 102 when cutting the soil-turning wall, in particular the side face or side region 122 of the soil-turning wall, is fully utilized. Thus, an energy-saving plowing device 3 is provided without negatively affecting the quality of the furrow pattern. In addition, the fixed second cutting element 105 squeezes the cut soil-turning wall in the direction towards the first cutting element 102, so that the cut soil-turning wall is broken. Furthermore, due to the lateral force introduced into the first carrier structure 4 by the upstream second cutting element 105, in particular via the contact plate 8, the lateral force caused on the first cutting element 102 during cutting is counteracted, enabling the plowing device 3 to be guided more simply and better by a tractor and even making following stability during plowing possible.

[0079] The first cutting element 102 and the second cutting element 105 are arranged relative to each other on the first carrier structure 4 and the second carrier structure 5 such that the front part of the second cutting element 105, i.e., its cutting edge, is at a distance x behind the first cutting region of the first cutting edge 103 of the first cutting element 102 in the plowing direction 110. Thus, during plowing, the fixedly arranged second cutting element 105 first laterally contacts the soil-turning wall and cuts it off from the remaining ground 120 in an energy-saving manner using the second cutting edge 106 of the second cutting element 105. Then, the first cutting element 102 cuts the side region 122 of the soil-turning wall with the first cutting edge 103. Here, the second cutting element 105 undercuts the furrow wall cut out by the first cutting element 102. Thereby, the subsequent first cutting element 102 of the subsequent plow module 1 can cut and turn the soil-turning wall laterally and vertically. Then, the soil-turning wall is rotated and placed in the adjacent furrow by the curved shape of the hollow disc serving as the first cutting element 102 and its inclined orientation relative to the plowing direction 110. Thus, the first cutting element 102 and the second cutting element 105 cut the soil-turning wall in an energy-saving manner, and the first and second cutting elements maintain the required cutting depth while the pressure acting on the second cutting element 105, wherein the contact plate 8 enables lateral support on the furrow wall to be achieved for the plowing device 3 in a stable following manner.

[0080] The second cutting element 105 undercuts the turned-up soil wall in a region (the flank). On the side of the second cutting element 105 facing away from the first cutting element 102, another fixing region of the second cutting element 105 is formed, and on this fixing region, fixing rods for fixing to the first load-bearing structure 4 are arranged. Thus, during plowing, the fixing rods travel in the already plowed furrow, which reduces the pulling force of the plowing device 3.

[0081] The first load-bearing structure 4 and the second load-bearing structure 5 are designed such that the first cutting element 102 and / or the second cutting element 105 can be adjusted relative to each other along the plowing direction 110 and / or vertically, i.e., perpendicular to the plowing direction 110. For example, the first cutting element 102 can be movably fixed to the first load-bearing structure 4 by a height adjustment device 16 of a hollow disk, and the height adjustment device 16 of the hollow disk cooperates with each other through the slots of the first load-bearing structure 4. By adjusting the distances of the first cutting element 102, the second cutting element 105 and the first load-bearing structure 4, the second load-bearing structure 5 along the plowing direction 110, the plowing device 3 can adapt to the special conditions of different types of ground and be used in an efficiency-optimized manner. In addition, if the elements warp after using the plowing device 3, the elements can be readjusted.

[0082] In addition, the first load-bearing structure 4 and the second load-bearing structure 5 can be designed such that the first cutting element 102 can be adjusted relative to each other along the direction component of the rotation axis 108 of the first cutting element 102, and the second cutting element 105 can be adjusted relative to each other along the direction component of its cutting blade extension direction. In particular, the angle between the rotation axis 108 of the first cutting element 102 and the longitudinal axis of the cutting blade can be adjusted. The first cutting element 102 and the second cutting element 105 are fixed to the corresponding first load-bearing structure 4 or the second load-bearing structure 5 relative to each other such that the cutting planes of the first cutting element and the second cutting element are not parallel and are angled with each other. For example, the angle between the rotation axis 108 of the first cutting element 102 and the longitudinal axis of the cutting blade is less than 90°, especially between 45° and 80°.

[0083] Figure 4 A rear view of the device according to Figure 3 is shown. The second load-bearing structure 5 for receiving the first load-bearing structure 4 is shown. A width adjustment device 15 is provided on the second load-bearing structure 5 connected to the first load-bearing structure 4, and through this width adjustment device 15, the distance between the first cutting element 102 in the form of a hollow disk and the second cutting element 105 in the form of the shown cutting blade 6 can be adjusted. Here, different width adjustments can be carried out by replaceable spacer washers. The contact plate 8 is shown above the cutting blade 6, and it is arranged for contacting along the furrow wall not shown in Figure 4 to achieve the following stability of the plowing device 3.

[0084] Finally, in Figure 5 a, Figure 5 b and Figure 5 c, three partial views of the plow module 1 according to the invention are shown.

[0085] Figure 5 b shows a rear view of the arrangement of the second cutting element 105 in the form of a cutting knife 6, wherein a contact plate 8 is provided for contacting the furrow wall, and the second cutting element 105 extends backward from the shown view. To make the arrangement of the first cutting element 102 and the second cutting element 105 in the plow module 1 clear, in the illustration according to Figure 5 b, hollow discs are shown respectively from the left and right sides of the second cutting element 105 with the contact plate 8. The back of the contact plate 8 has a reinforcing plate 9, which gives the contact plate 8 (see Figure 5 c) greater strength and stability. A hinge 7 is shown, by which the second cutting element 105 in the form of a cutting knife 6 can be variably adjusted with respect to the first carrier structure 4 in terms of its attack angle. In addition, a height adjustment device 13 for the cutting knife is shown, by which the height of the cutting knife - carrier - structure - unit can be adjusted relative to the chassis 2 of the plowing device 3 or the plow beam. The height adjustment device 13 for the cutting knife relates to the height adjustment of the cutting knife 6. In addition, another height adjustment device for the first cutting element 102 is provided in the form of a hollow disc.

[0086] Figure 5 a shows a view of the plow module 1 according to the invention from the right side of the rear view shown in Figure 5 b, while Figure 5 c shows a side view of the rear view according to Figure 5 b from the left side.

[0087] The pivotability of the second cutting element 105 in the form of a cutting knife 6 around the hinge 7 is indicated by the double arrow 12 in Figure 5 a. The corresponding locking of the set attack angle of the cutting knife 6 is carried out by the tilt fixing device 11.

[0088] Relative to the side view of the rear view according to Figure 5 b, Figure 5 c is shown from the left side. For stable following, the contact plate 8 contacts the furrow wall not shown in Figure 5 c for longitudinal guidance, while for the turnover wall that is still to be separated from the shown hollow disc and turned over, the cutting knife 6 has already cut the bottom 121 of the furrow at a certain depth in the ground to be plowed. Since the cutting knife 6 passes through the contact plate 8 and is fixed in place there, and can also pivot together with the cutting knife 6 through the hinge 7, this means that even if the attack angle changes, the contact plate 8 always pivots together with the cutting knife 6.
