Description

The invention relates to a soil cultivating machine, in particular a hoe, for cultivating agricultural land. The soil cultivation machine is designed in particular for the cultivation of plants grown in rows, such as maize, beets or the like.

A wide variety of tillage machines, in particular hoeing devices, are known from the prior art for mechanical weed control on agricultural areas. Such a soil cultivating machine goes, for example DE 36 16 403 A1 already emerged. Here, a chopping device is described with a machine beam composed of a central frame and two side frames, on which tools for row-by-row cultivation of an agricultural area can be attached. In order to achieve a favorable overall center of gravity in relation to an agricultural towing vehicle in the transport position, it is provided that the side frames are arranged offset in relation to the central frame in the direction of travel.

Another tillage machine, in particular a hoe, became known through the Austrian company "Einböck GmbH & CoKG" with the product name "CHOPSTAR". This product has different additional names depending on the number of possible rows to be processed in a row crop and the spacing of the tools, for example "CHOPSTAR 60-90". In order to be able to use the hoe in embankment crops and to achieve precise guidance to the respective row crops, it includes flange wheels. Although the guidance of the chopping device can be improved by means of such flange wheels, their arrangement, known from the prior art, sometimes also has various disadvantages.

So far, two different arrangements of such flange wheels are known. A first embodiment variant provides that the flange wheels are arranged below the machine beam or a section of a machine beam. However, this has the disadvantage that the ground clearance of the hoeing device is reduced and thus the hoeing device can only be used to a limited extent, both with larger plants and with dam crops. As an alternative to this, an arrangement of the flange wheels in front of the machine frame is also known, in particular through the "CHOPSTAR" hoe. However, this arrangement again has the disadvantage that such an arrangement of the machine beam is shifted backwards in relation to a hitching device by means of which the chopping device can be connected to an agricultural towing vehicle and thus the distance is increased. However, this has negative effects on the driving behavior of the towing vehicle, since the center of gravity of the chopping device has a greater distance from the towing vehicle. In addition, lateral guidance is often not possible or only insufficiently possible due to the short lever lengths.

The invention is therefore based on the object of providing a soil cultivation machine, in particular a chopping device for cultivating agricultural land, with which the disadvantages of conventional soil cultivation machines can be avoided. The invention is based in particular on the object of making available a soil cultivating machine in which, despite the use of flange wheels, an optimized weight distribution and a high ground clearance are achieved.

The objects are achieved by a soil cultivating machine with the features of independent claim 1. Advantageous developments of the invention are specified in the dependent claims and the description.

The invention relates to a soil cultivating machine, in particular a hoe, for cultivating agricultural land, with a multi-part support beam that can be attached to a trailer hitch of a towing vehicle and extends essentially horizontally and transversely to the forward direction in a working position, the support beam being attached to a central part and pivotably on the central part Side parts is assembled, wherein the middle part and the side parts each have a mounting surface which is oriented transversely to the forward direction and at least largely aligned and / or parallel to one another, with tools arranged at a distance from one another being mounted indirectly and / or directly on the mounting surface, and with at least a flange wheel or several flange wheels.

In order to provide a soil tillage machine in which an optimized weight distribution and high ground clearance is achieved despite the use of flange wheels, the invention provides that the center of at least one flange wheel or of several flange wheels opposite a forward direction at the same height or behind the mounting surface of the Middle part is arranged.

The soil cultivation machine according to the invention is in particular a chopping device. The chopping device can be used appropriately for processing row crops grown in rows, such as maize, beets or the like. In particular, the soil cultivating machine according to the invention can be used for mechanical weed control of crops grown in rows. The soil cultivation machine, in particular the hoe, can be designed in such a way that it is also suitable for the cultivation of row crops grown in embankments, which is achieved in particular by the high ground clearance achieved by means of the soil cultivation machine according to the invention. The soil cultivation machine can expediently be used in such a way that by means of it the free spaces of the agricultural area between the rows of a row crop are processed and / or the rows of the row crop are processed.

As a result of the measures according to the invention, the use of at least one flange wheel ensures that the tillage machine is guided in a true-to-track manner, for example along a row crop, but at the same time the ground clearance is not reduced and the center of gravity of the tillage machine is essentially not shifted backwards.

In order to create a soil cultivating machine which has a large working width and still be able to adhere to a maximum transport width permissible for a transport journey, the side parts can also be attached to the middle part so that they can pivot about essentially horizontal axes extending in the forward direction.

The soil cultivation machine according to the invention can have a large working width of several meters. E.g. the soil tillage machine can have a working width of 6 meters or 9 meters or more. Insofar as the soil cultivation machine is designed as a hoe, the working width can vary depending on the rows of a row crop to be processed.

In order to create a soil cultivating machine that can be used as variably as possible, in particular in order not to influence the work of the tools by means of the at least one flange wheel, a development of the invention can provide that at least the center of a flange wheel is arranged at least in sections at the level of the rear end of the tools , in particular at the level of the rear end of the tools which are arranged next to the at least one flange wheel, or that the center points of several flange wheels are arranged at least in sections at the level of the rear end of the tools, in particular at the level of the rear end of the tools which are directly next to at least one of the several flange wheels are arranged.

In order to improve this even further, it can be provided according to a further embodiment variant that at least one flange wheel is arranged with the full circumference adjacent and / or behind the rear end of the tools, in particular with the full circumference adjacent and / or behind the rear end of the tools , which are arranged directly next to the at least one flange wheel.

It should be pointed out that the definition, in addition to the flange wheel, is intended to include in particular the tools that can be influenced by the flange wheel, expediently the tools that can be hindered in its freedom of movement by the flange wheel. Whereby these are in particular the tools which are arranged at least in sections next to at least one flange wheel.

Due to the inventive arrangement of the center point of the at least one flange wheel behind the support beam, the guidance of the tillage machine is significantly improved compared to the tillage machines known from the prior art, since a correspondingly large leverage effect is generated between a hitching device of an agricultural tractor and at least one flange wheel and thus the transverse and / or lateral forces acting on the soil tillage machine and / or the tools can be absorbed in a correspondingly improved manner.

In order to reduce the number of flange wheels required to a minimum and at the same time to achieve a compact soil cultivation machine, it can be provided according to an embodiment of the invention that the distance between the mounting surface and the center of at least one flange wheel and / or the multiple flange wheels,
is at least 10cm, at least 50cm or at least 100cm and / or at most 600cm, at most 500cm or at most 400cm and / or at least corresponds to the diameter of at least one flange wheel.

To assemble the tools for soil cultivation, the soil cultivation machine comprises an in particular multi-part support beam. The carrier beam has a width that essentially corresponds to the working width of the soil cultivating machine. The support beam comprises a central part and side parts which are attached to the central part so as to be pivotable about essentially horizontal axes extending in the forward direction. The middle part and / or the side parts can also be designed in particular in several parts, the individual parts by means of non-detachable (eg welding) and / or releasable (for example screws or the like. Machine elements) connection can be connected.

In order to create a soil cultivating machine in which at least approximately constant conditions can be achieved for the tools over the entire working width, the support beam can be composed of a central part and side parts pivotably attached to the central part, the central part and the side parts each have a mounting surface which is oriented transversely to the forward direction and are at least largely in alignment and / or parallel to one another. With a parallel arrangement of the mounting surfaces, it can be provided that the distance between the mounting surfaces of the side parts and the central part is in particular less than or equal to 100 cm or 50 cm. The respective tools can be mounted indirectly and / or directly on the mounting surface.

According to an alternative embodiment variant, the mounting surface can provide a clamping system by means of which the tools can be attached directly and / or indirectly to any desired position on the support beam. A wide variety of tools can thus expediently be attached to the support beam at different distances from one another.

In order to simplify the direct and / or indirect assembly of the tools on the support beam, in particular to provide a simply constructed clamping system, it can be provided that the support beam comprises at least one profile tube, with the mounting surface in particular being formed by a surface of a profile tube . In particular, the back, i.e. the rear end of the profile tube can be designed as a mounting surface. For example, in the case of a profile tube formed as a square tube, the rear side can form the mounting surface in relation to the forward direction.

The tools can be any components suitable for soil cultivation. The tools can also be suitable or designed for sowing. The tools can expediently include tillage coulters and / or tines and / or harrows and / or seed coulters and / or finger hoes and / or the like and / or correspond to such. Combinations of tillage shares and / or tines and / or harrows and / or seed shares and / or finger hoes and / or the like are also conceivable and usable.

The tools can be installed directly on the support beam, that is to say without any component between them. According to a further embodiment variant, the tools can also be attached indirectly to the support beam. The indirect assembly of the tools can take place by means of a carrier which is arranged, in particular, in a height-adjustable manner with respect to the carrier beam, and a tool can be built onto the carrier or two or more identical and / or different tools can be added. If the tools are built onto one or more carriers, this can also form the rear end of the tools, depending on the design of the carrier.

In order to be able to work a plurality of rows of a row crop, a plurality of tools and / or carriers with tools at a distance from one another are attached directly and / or indirectly to the carrier beam, expediently on the mounting surface, according to one embodiment of the soil cultivation machine. The distance can be the same as the distance between the rows of a row crop. The number of tools and / or carriers can be the same as the number of rows of a row crop, or one tool and / or carrier or two more tools and / or carriers can be present on the tillage machine than rows of a row crop can be worked with on both sides can.

The tools and / or the carriers can have an average distance from one another which is greater than the width of a row of a row crop, the distance being at least 10 cm or at least 25 cm or at least 50 cm.

In order to achieve an optimal height guidance of the tools along the agricultural area, it can be provided according to a further development of the invention that the tools are installed in a height-adjustable manner relative to the carrier beam. The height adjustment can take place, for example, by means of a parallelogram arranged between the support beam and the tools and / or the support.

According to a further development of the invention, the tools and / or the carriers can be used to vary and / or control and / or regulate the working depth, i.e. to vary and / or control and / or regulate the height position of the tools and / or the carriers in relation to the support beam can be adjusted by means of an actuator. The actuator can, for example, be a hydraulically and / or pneumatically and / or electrically operated actuator, in particular a hydraulically and / or pneumatically and / or electrically operated cylinder, linear drive or the like. Alternatively and / or in addition, the working depth can also be achieved by means of a mechanical adjustment element (eg spindle, plug-in system, limiting system or the like.).

In order to maintain the desired working depth of the tools as precisely as possible, provision can be made be that the tool and / or tools attached to the carrier is arranged upstream and / or downstream of a depth control roller and / or that a depth control roller is arranged between the tools.

In order to be able to move the support beam, expediently the middle part and the side parts at a constant distance from a floor surface along an agricultural area, support wheels can be assigned to the support beam, expediently the middle part and / or the side parts. The support wheels can be arranged upstream of and / or downstream of the support beam. The support wheels can also have a distance of at most 300 cm or at most 250 cm or at most 100 cm from the outer end of the carrier beam.

In order to be able to vary and / or control and / or regulate the height guidance, that is, the height distance of the support beam to an agricultural area, it can be provided according to a further development of the invention that the support wheels are attached in a height-adjustable manner relative to the support beam. To vary and / or control and / or regulate the height position of the support beam, the support wheels can be height-adjustable by means of an actuator. The actuator can, for example, be a hydraulically and / or pneumatically and / or electrically operated actuator, in particular a hydraulically and / or pneumatically and / or electrically operated cylinder, linear drive or the like. Alternatively and / or additionally, the variation and / or control and / or control can also take place by means of a mechanical adjusting element (eg spindle, plug-in system, limiting element or the like).

It is possible that the height distance and thus the ground clearance of the support beam can be varied and / or controlled and / or regulated accordingly as a function of the tools and / or the working depth. In particular, the height distance can be variable and / or controllable and / or regulatable as a function of the height of a plant population and / or a dam.

In order to provide a soil cultivating machine with a large working width, which can nevertheless be brought to a transport size required for road transport, a further development of the invention can provide that the side parts are composed of two or more individual segments, i.e. the support bar of the side parts can have two or more divided. The individual segments can also be pivotable to one another by means of axes of rotation extending essentially parallel to the forward direction. The individual segments can, for example, be pivoted relative to one another by means of a 180 ° fold known to a person skilled in the art. The individual segments can also be pivoted relative to one another by means of a package folding mechanism known to a person skilled in the art.

In order to pivot the side parts to the middle part and / or the individual segments of the side parts to one another, linear drives can also be provided, in particular hydraulically and / or pneumatically operated cylinders. The linear drives can also be in operative connection with a control device. The control device can be designed in such a way that the linear drives are controlled during operation of the soil cultivation machine in such a way that movement of the side parts to the middle part and / or the individual segments of the side parts to one another is prevented and / or made possible. According to a further embodiment variant, the freedom of movement can also be limited.

In order to be able to guide the tools as precisely as possible along the rows of a row crop, it can be provided that the central part is essentially divided into two parts. In particular, it can be provided that the middle part is composed of a sliding frame and a guide frame. The sash frame can expediently be stored in the guide frame.

According to a development of the invention, the sash frame can be slidably mounted in the guide frame, that is, it can be provided that the guide frame and the sash frame are designed in such a way and / or include such components, parts or the like that these, that is to say that the The sash frame and the guide frame form a plain bearing.

In order to be able to guide all tools directly or indirectly attached to the mounting surfaces exactly along the rows of a row crop, it can advantageously be provided that the support beam of the central part or the mounting surface of the central part is part of the sash frame and that the side parts are pivotably connected to the sliding frame are. This ensures that all tools can be moved transversely to the forward direction in relation to the guide frame and thus all tools can be moved evenly.

For the exact control and / or regulation of the position of the tools along the rows of a row crop, according to an alternative embodiment variant, an adjusting device can be arranged between the guide frame and the sliding frame. The adjusting device can be formed, for example, by one or two or more hydraulically and / or pneumatically and / or electrically operated drives, motors, cylinders or the like. The adjusting device with a Control device can be operatively connected, which control device is designed to control and / or regulate the actuating device accordingly. In particular, the actuating device and the control device are designed in such a way that a position of the sliding frame relative to the guide frame can be varied, in particular controlled and / or regulated. In order to be able to vary and / or control and / or regulate the position of the tools even more precisely, it can be provided that the control device has optical and / or sensory detection devices which are designed in such a way that the relative position of the sliding frame to the guide frame can be determined on the basis of these . The relative position of the sash frame to the guide frame can be determined, for example, on the basis of a detected current position of the sash frame in relation to a row of a row crop and the relative position can be determined accordingly, in particular calculated, by means of the control device.

To connect the soil tillage machine to a hitch of an agricultural tractor (e.g. tractor), a coupling frame can be assigned to the middle part, in particular the guide frame, the coupling frame having at least one upper coupling point and / or one lower coupling point. In particular, it can be provided that the coupling frame essentially has an upper coupling point and two lower coupling points, whereby the upper coupling point and the lower coupling point form a three-point attachment. The upper coupling point and the lower coupling point can expediently be formed by an axis extending essentially transversely to the forward direction, which axes can lie transversely to the direction of travel on a common plane and / or can be parallel to one another.

In turn, other variants of coupling frames would or are also conceivable. According to an alternative embodiment, the coupling frame can also be designed in such a way that the soil cultivation machine can be operated in the rear attachment of a towing vehicle and / or that the soil cultivation machine can be operated in the front attachment of a towing vehicle.

According to a first embodiment variant, at least one flange wheel can have one or more flange wheels, a web (s) or elevation (s) protruding above a running surface. According to a further embodiment variant, the flange wheel can have one or more recess (s). The web and / or webs can have a substantially uninterrupted circumferential surface a and / or a profiled circumferential surface and / or an interrupted circumferential surface. The flange wheel can have a hollow body. The flange wheel can be formed from a metallic material, and the flange wheel can also be formed from a plastic material or some other non-ferrous material.

The flange wheel can have a substantially T-shaped and / or V-shaped and / or U-shaped and / or W-shaped and / or M-shaped circumferential surface. Other contours of the circumferential surface would also be conceivable or usable.

At least one flange wheel is manufactured in such a way that it has one or more webs which can penetrate into a floor surface for guiding the soil cultivation machine. In addition, the flange wheel can each have at least one section which has an essentially flat and / or conical circumferential surface, which circumferential surface is adjacent and / or adjoining the one or more webs, with the respective penetration depth of the one or more webs by means of this circumferential surface several webs can be limited in the floor area.

At least one flanged wheel or several flanged wheels can be connected to the central part. In particular, at least one flanged wheel or several flanged wheels can be connected to the guide frame or be attached to it. As an alternative or in addition, it would also be conceivable that at least one flange wheel is connected to a side part. This means that, on the one hand, the tools can be moved transversely to the forward direction by means of the sliding frame, but the guide frame can at least keep its position in relation to the rows of a row crop at least largely constant, which results in a significantly improved processing of rows, i.e. planting a row crop is achieved. Expediently, by guiding the tillage machine by means of the flange wheel or wheels, the sliding frame can be moved parallel to the guide frame and the tools can thus be moved at least largely parallel to the rows of a row crop in relation to its forward direction. It can thus be achieved in particular that the tools can each be displaced without an angular offset to the rows of a row crop.

In order to improve the guidance even further, it would also be conceivable, according to a further development of the invention, that at least one flange wheel or several flange wheels can be actively and / or passively steered. Active steering can provide, for example, that the orientation of the at least one flange wheel with respect to a forward direction can be actively changed, in particular controlled and / or regulated, by means of an actuating element is. Whereby the actuating element can also be operatively connected to a control device, the orientation and / or alignment can therefore expediently deviate from the forward direction. In contrast, passive steering can provide that at least one flange wheel or several flange wheels is rotatably mounted on the guide frame and the orientation or alignment follows the direction of travel of an agricultural tractor, in particular is parallel to the forward direction. Optionally, that is to say activatable and / or deactivatable active and / or passive steering can also be provided.

In order to be able to vary and / or control and / or regulate the height guidance, i.e. the height distance of the carrier beam to an agricultural area, a further development of the invention can provide that at least one flange wheel or several flange wheels are height-adjustable relative to the carrier beam. In order to vary and / or control and / or regulate the height position of the at least one flange wheel or the several flange wheels, this or these can be height-adjustable by means of one or more actuators. The actuator can be, for example, a hydraulically and / or pneumatically and / or electrically operated actuator, in particular a hydraulically and / or pneumatically and / or electrically operated cylinder, linear drive or the like. Alternatively and / or in addition, the variation and / or control- and / or regulation also take place by means of a mechanical adjusting element (eg spindle, plug-in system, limiting element or the like).

To achieve sufficient freedom of movement of the tools, it can be provided that the at least one flange wheel or several flange wheels are connected to the central part, in particular connected to the guide frame, expediently connected to the guide frame by means of a connecting section.

In order to increase the freedom of movement accordingly to a maximum and still achieve a compactly built soil cultivating machine, it can be provided that the connecting section has a first section which is designed to widen in the opposite direction to the forward direction in relation to the tools (increasing distance to tools) and which first section merges into a second section after reaching an apex, the second section tapering in relation to the tools (decreasing distance to tools).

In order not to impair the freedom of movement of the tools through the connecting section, it can be provided that the connecting section has a width which is smaller than the distance between two directly adjacent tool carriers or from two directly adjacent tools arranged on the carrier beam, in particular the Connecting section in the region of the apex has a width which is smaller than the distance between two directly adjacent tools each attached to a carrier. It can thus be achieved that the connecting section can be attached between two tools and / or carriers.

It can be provided that the soil cultivation machine has at least two flange wheels which have an average distance from one another which is at least 100 cm or at least 125 cm or at least 150 cm.

According to a further embodiment variant, it can be provided that the soil cultivating machine comprises at least two flange wheels which can be mounted on a connecting section, and the mean distance between them being variably adjustable.

According to a development of the invention, the flange wheels can be arranged between tools and / or carriers in relation to the forward direction.

It is possible for the soil cultivation machine to have at least one additional flange wheel, which is arranged at least in sections in front of the carrier beam and / or is arranged next to the carrier beam.

According to a further development of the invention, it can also be provided that the support wheels are also formed by flange wheels.

It should also be noted that the terms “control” and “regulate” or “control device” can refer to electronic and / or pneumatic and / or hydraulic controls that, depending on the training, can take on control tasks and / or regulation tasks. Even if the term “control” is used here, it can also expediently include “rules”. Likewise, when using the term “regulating”, “controlling” can also be included.
