    专利说明:

    The present invention relates to a device for removing and chopping, in particular mulching, weeds, undersown or the like between cultivated plants planted in rows, with a plurality of tools assigned to individual rows of plants, which are mounted on a carrier of an agricultural vehicle.
    In connection with the removal and comminution of weeds, undersown or the like between crop plants planted in rows, it is known to remove such undesired plants between the crop plants by means of appropriate tillage implements, usually using hackers or similar devices, such as, for example, the FR-Al 2 812 7 90 or EP-A2 0 914 7 60 can be found. In the case of such chopping devices, in addition to removing the undesired plants, the top layer of the soil is crushed or lifted off, so that strong soil erosion occurs, for example, in the case of subsequent heavy rain or thunderstorms, particularly in the case of soils located on slopes. Such soil erosion not only transports valuable arable soil, but also threatens subsequent settlement areas, whereby the removal of the top and usually the most fertile soil layer also means that corresponding economic damage for the use of such arable soil will be unavoidable in future years.
    The present invention therefore aims to avoid the above-mentioned disadvantages of existing devices for removing unwanted plants between crop plants planted in rows and, in particular, to avoid or, respectively, the disadvantageous effects of soil erosion, as occurs through the use of known chopping devices or similar devices at least to reduce as much as possible
    To solve these tasks, a device of the type mentioned at the outset is essentially characterized in that the individual tools, which in particular each have at least one rotating knife, each around a substantially horizontal and in the direction of travel of the vehicle and in the direction of the substantially parallel mutually oriented rows of plants are pivotally guided pivot axis. It is thus proposed according to the invention that the tools, for example mounted on a carrier of an agricultural vehicle, are each formed by a knife, which is used for chopping and mulching weeds, undersowing or the like between the crop plants planted in rows, the tools formed by knives cut or shred these unwanted plants between the crop plants just above the soil, leaving the top soil layer untouched in contrast to known hoeing equipment. For an adaptation and essentially complete removal of undesired plants growing between the individual rows of plants and to be removed, it is provided according to the invention that the individual tools each have an essentially horizontal pivot axis oriented in the direction of travel of the vehicle and in the direction of the essentially parallel rows of plants are displaceably guided, so that it is possible in this way, even if the agricultural vehicle is possibly not moving directly and completely parallel to the rows of plants, by means of such swiveling or compensating movements between the individual tools, only the undesirable ones to be removed between the rows of plants Shred and remove plants or mulch plants. As a result of the comminution or mulching of the undesired plants between the crop plants proposed according to the invention, in addition to protecting the uppermost soil layer to avoid soil erosion, a corresponding fertilization by the comminuted plants is achieved at the same time. In addition to such an improvement in soil fertility through a build-up of humus, the shredded or mulched plants suppress a new growth of / 21
    Weeds, undersowing or the like. In addition, the resultant soil shading reduces soil warming, so that such a reduction in the soil temperature also promotes the survival or activity of soil organisms. In addition, precipitation is better absorbed by the soil and, in particular, the occurrence of soil erosion by removing the top soil layer during heavy rain or thunderstorms is prevented or at least significantly reduced.
    For a structurally particularly reliable and simple embodiment, it is also proposed that in each case at least one tool is mounted on or in a frame which is movably articulated on the carrier, as corresponds to a preferred embodiment of the device according to the invention. Such a frame, on which in each case at least one tool is mounted, wherein such a frame can also be provided, for example, with a corresponding drive device for the tool formed by a knife, can be correspondingly reliably articulated on the carrier, so that the frame articulated on the carrier reliable guidance of the tool between the rows of plants is possible.
    In order to improve the guidance of the tools or their frames between the rows of plants, it is proposed according to a further preferred embodiment that the tools or their frames are guided through the plants of the rows of plants in particular by means of lateral guide devices, in particular guide plates on their outer circumferences in the direction of travel of the vehicle. The individual tools on the plants in the rows of plants can be guided safely and reliably by such guide devices or guide plates, the plants being appropriately protected by appropriate shaping of the guide devices. By adapting the tools or their frames to the predetermined spacing of the rows of plants, a safe and reliable removal of the undesired plants growing between the rows of plants / 21, such as, for example, weeds,
    Undersowing or the like possible.
    For a reliable support of the guide devices on a possibly uneven surface, it is also proposed that the guide devices can be raised and lowered in relation to the associated frame, in particular for support on the floor surface, as corresponds to a further preferred embodiment of the device according to the invention.
    In order to improve the guidance of the guide devices and to protect the crop plants grown or planted in the rows of plants, it is provided according to a further preferred embodiment that the guide devices at their front end areas in the direction of travel with essentially inward to a central area of the tool or frame and in particular Ends directed upward from the bottom surface are formed. The crop plants are appropriately protected by such ends which essentially point inwards towards a central region of the tool or frame and in particular upwards. Furthermore, such protruding ends, for example in the case of plants growing in particular in the soil, such as beets, enable the leaves of this crop to be raised, so that they are not removed or shredded by the tools like the plants to be removed between the rows.
    In particular, in order to maintain a substantially uniform vertical distance between the knives of the tools and a possibly non-uniform or flat floor surface, in order to enable the plants to be removed to be removed or cut in a substantially uniform manner, it is also proposed that the tools or the frames of which can additionally be moved in the vertical direction, preferably by means of a feeler wheel to maintain a substantially predetermined or predeterminable distance from the floor surface, as is a further preferred embodiment of the / 21 according to the invention
    Device corresponds. With such a feeler wheel, a substantially constant vertical distance of the knives or tools from the ground surface can be achieved, so that, for example, slopes with a plurality of tools arranged on a carrier or their frames also occur with such a carrier essentially unchanged can be processed in an agricultural vehicle.
    In order to achieve reliable swivel or displacement movements in a plurality of swivel or movement directions or around a plurality of swivel axes, as stated above, it is proposed according to a further preferred embodiment that the swivel movements or displacement movements of the tools or Frames are formed over a plurality of parallelogram links arranged between the carrier and in each case one frame of the individual tools. Such parallelogram links can also be designed to be correspondingly robust and reliable and enable reliable mechanical guidance of the individual tools or their frames, in particular on the crop plants planted in rows.
    To further increase the usability of the device according to the invention, it is proposed according to a further preferred embodiment that the tools or frames are additionally mounted so as to be pivotable about a substantially vertical axis relative to the carrier. Such additional pivotability about an essentially vertical axis also allows, for example, corresponding cornering or the processing of rows of plants which are not planted in a completely straight line.
    For an adaptation of the device according to the invention for use with possibly different crop plants or crop plants planted at different distances, it is also proposed that the width of the tools or frame in the direction of travel be adjusted or adjustable to match a distance between / 21 individual rows of plants, as is the case here corresponds to a further preferred embodiment of the device according to the invention.
    For further adaptation to possibly different operating conditions, for example for use on ends of a planted ground surface which run obliquely to the respective rows of plants, it is proposed according to a further preferred embodiment that each tool or each frame can be raised and lowered separately on the carrier, in particular with interposition a cylinder-piston unit is mounted. By lifting and lowering individual tools or frames separately in this way, individual tools can be raised, for example, when a floor or plot area is reached, while with remaining tools, for example, rows of plants located at another end of the carrier can be processed accordingly up to the end of the floor area .
    According to a further preferred embodiment, it is provided that the tools or frames are arranged or fixed on a carrier arranged in front of the agricultural vehicle in the direction of travel. Processing, in particular removal and comminution of plants to be removed, takes place between the crop plants in front of the agricultural vehicle, so that, for example in contrast to an arrangement of a carrier with the tools behind the agricultural vehicle, the plants to be removed or comminuted do not do so beforehand are depressed by the wheels of the agricultural vehicle, so that a corresponding removal and comminution is made difficult or impossible.
    Since distances at edge areas of planted soil areas usually have a smaller distance between the crop plants planted in rows than such a boundary area than the distance between the individual rows of plants and taking into account the fact that large area areas are usually cultivated by repeated driving with an agricultural vehicle According to a further preferred embodiment, it is proposed that tools or frames arranged on the outer ends of the carrier have a width that is smaller than the distance between the rows of plants and the width of the other tools. Such tools or frames with a reduced width on the outer regions make it possible to also process narrower edge regions, if necessary, and / or take into account that, when the agricultural vehicle is used again, subsequent areas planted with a remaining partial region between rows of edges located at the edge Crops is treated accordingly by reworking the subsequent areas.

    In the introduction to the following detailed description, it is noted that only the elements that are essential for understanding the present invention are described in detail in the drawing and provided with reference numerals in order to simplify the description and the representations accordingly.
    From the schematic partial representation according to FIG. 2 it can be seen that a unit 1, which is not completely shown in this figure, is mounted on the carrier 3 via a plurality of articulated connections, wherein 8 denotes a bearing which is fixed on the carrier 3 and which has a parallelogram link 9 with a Tool carrier 10 cooperates, the tool and a frame for this are shown in detail for example in FIGS. 5 and 6.
    The tool carrier 10 is supported by a feeler wheel designated 11 on a floor surface designated 12, additional elements for a height adjustment of the feeler wheel 11 being indicated generally by 13. By adjusting the height of the feeler wheel 11, a remaining height of the plants to be removed or shredded between the rows of plants can be set accordingly.
    For lifting the tool carrier 10 and the associated tool or frame, as will become apparent below, a cylinder piston 10/21 is additionally shown in FIG. 2 ·· - · ι · β - ·: · .. ·
    Unit 14 can be seen, through which by extending the
    Piston over the parallelogram 9 by lifting the
    Tool carrier 10 a lifting or removing the feeler wheel 11 from the floor surface 12 is possible.
    It can be seen from the representations according to FIGS. 3a and 3b and FIGS. 4a and 4b that pivoting of the tool carrier 10 relative to a central axis 15 of the feeler wheel 11 is possible in that, as can be seen in particular from FIGS. 3b and 4b , on the tool carrier 10 side pendulums 16 are provided, which relocate the entire suspension of the tool carrier 10 and a tool or frame mounted therein, as will become clear below, relative to the central axis 15 and thus by one in FIG. 4b make possible schematically designated axis 17, which runs essentially horizontally and in the direction of travel, as indicated by an arrow X in FIG. 1, and in the direction of the rows 2 of plants.
    With the side pendulums 16, in particular in FIGS. 4a and 4b, additional cylinders 18 are indicated in order to enable a return to a central or central position, as shown in FIG. 3a, corresponding extensions 19 are coupled, which one enable appropriate support or mounting of the tools or frames shown in the following figures.
    In the schematic plan view according to FIG. 5, instead of the representation of both the tool carrier 10 and the elements for pivoting about an essentially horizontal axis, a frame or tool holder 20 and, schematically, 21 a tool formed by a knife are shown, with an additional one Motor 22 for driving the knife 21 for removing and chopping plants located between the rows of plants to be removed, such as weeds, undersowing or the like. Is indicated.

    5 that the frame 20 is provided with telescopic extensions 23, which can be adjusted in accordance with the double arrow, with corresponding different settings in FIG Fig. 5 indicate different possible widths relative to the articulation point of the knife 21.
    In addition to a position of the frame 20 and thus of the knife 21 which is offset from the central longitudinal axis 15, similar to the illustration according to FIG. 4a, an inclined position of the frame 20 relative to the central axis 15 can also be seen in FIG. 5, in particular for cornering, with a pivoting around such an essentially vertical axis takes place about a pivot or pivot point schematically indicated by 24 in FIGS. 3a and 4a.
    6 and 7a and 7b show that guide devices 7 are arranged on the outer areas or outer circumferences of each unit schematically designated by 4 in FIG. 1, which, as can be seen in particular from FIGS. 7a and 7b, are pivotally coupled via a lever or pivot connection 25 to a bearing point 26 coupled to the frame 20.
    In addition to ends 27 which are essentially bent inwards and upwards and which permit simple and gentle guidance of the entire units 4 on the plants 2, which in turn also schematically denotes 2 in FIG. 6, the guide devices or guide plates 7 are relative via the swivel connections 25 to the tool or knife, again designated 21 in FIGS. 7a and 7b, can be adjusted in the vertical direction in accordance with the indicated double arrow. As a result of this adjustability, the guide devices 7 can be supported essentially over the entire length of the same, even on uneven floor surfaces, and thus reliable guidance on the plants 2 of the rows of plants.
    / 21
    Due to the multiple adjustability or partial steerability of the individual units 4, in particular by guiding the plant rows 2, the width b of the individual units 4 can be adapted directly to the distance of the plants 2 in the plant rows and even if the agricultural vehicle 5 is not optimally positioned relative to the rows of plants 2, due to the multiple adjustability provided, plants growing, to be removed or to be shredded can be carried out between the plants 2 of the rows of plants.
