Definitions

  • the invention relates to a hand-held floor preparation device for processing floors by scrubbing, polishing or grinding.
  • a device for the treatment of surfaces is known, in particular for cleaning and polishing, which provides a joint that can be moved in at least two directions between a holding device and the base part.
  • This joint allows the user to adjust the handle height to the personal size of the user by tilting the holding device and to move the device back and forth in the processing direction, as well as to carry out lateral movements with the device.
  • a steam scrubbing machine which has a handle part which can be moved relative to the base part in the working direction and which has a water tank, a water pump, a heater and a steam distributor on the base part.
  • a vacuum cleaner unit which is also attached to the base part, is disclosed for dry cleaning, comprising an intake chamber, an intake pump, a suction channel and an intake opening.
  • backpack vacuum cleaners with a back unit and a carrying frame are known, in which the back unit comprises at least one intake pump and one intake chamber.
  • the back unit comprises at least one intake pump and one intake chamber.
  • an energy storage device for supplying energy to the pump can also be provided in the back unit.
  • the DE 196 22 856 A1 discloses a hand-held surface scrubber having at least one, preferably two, disk brushes and at least one roller brush, and which is supported on wheels to move. Furthermore, a suction strip is provided, which is preferably attached to the rear end of the cleaning device and which is connected via a hose to a receptacle for dirty water. A cleaning fluid reservoir is also attached to the surface scrubber.
  • this surface scrubber has the disadvantages that its weight is increased by the liquid containers attached to the device itself, and that the wheels allow easy movement in a linear direction but do not allow real mobility in a lateral direction.
  • a lip for a mop which has on one side surface thereof protrusions along its length with non-protruding spaces between the protrusions extending upwards from the lower edge, the other side surface being smooth.
  • this lip When this lip is moved over a floor with its smooth side, it forms a seal with the floor that does not let water through. If the lip with the side surface having projections is moved over the floor, water can flow through the gaps mentioned. This allows a suction unit consisting of two respective lips to absorb water in two directions, back and forth.
  • a hand-held floor preparation device in the form of a polishing device for polishing surfaces is known.
  • the well-known polishing device has a base part with a polishing tool, a guide part with a handle part and a liquid feed.
  • the guide part is connected to the base part via a double joint with orthogonally aligned joint axes.
  • the polishing tool has counter-rotating rollers.
  • the liquid supply is arranged in the form of a spray arrangement on the bottom part and allows a spray to be sprayed onto the rollers.
  • the invention is based on the object of providing a floor treatment device which, in addition to polishing or grinding, also enables wet cleaning and is easily movable and operable by hand.
  • the invention relates to a hand-held soil cultivation device with the features of claim 1.

  • the other joint forms a cardan joint with the first joint and allows a user to rotate the base part within the working plane, even if the guide part is inclined about the first joint axis to the vertical axis of the base part, which allows the base part to be very mobile.
  • the working direction of the floor part can be swiveled parallel to the floor, even when the guide part is at an angle, and allows easy working in corners or niches or under projections.
  • any rotation of the bottom part about its vertical axis is possible by means of such a cardan joint, even when the guide part is set at an angle.
  • the user can rotate the base part by at least ⁇ 270° parallel to the working surface about the vertical axis of the base part.
  • This mobility enables easy cleaning of corners, niches or projections, for example under stairs or tables.
  • the mobility enables cleaning both in the forward and backward direction, as well as in the lateral direction, even if the guide part is inclined about the first joint axis to the vertical axis of the base part, whereby the soil tillage implement can always be moved in the tillage direction, which is a prerequisite for represents a regular intake of the liquid.
  • the base part is supported exclusively on the tool for tilling the soil.
  • the mobility of the base part is not restricted by a support device.
  • the tool for tilling the soil consists of at least two counter-rotating and substantially horizontally rotating drive plates with tillage attachments.
  • processing attachments can be brushes, discs for pads or grinding wheels.
  • the soil tillage device can be used for a wide variety of jobs such as polishing, scrubbing or grinding.
  • the soil cultivation device has at least one energy store and/or a power cable to an external energy supply to supply the tool.
  • the weight of the base part can thereby be kept low, which enables the user to easily move and guide the base part by means of the guide part.
  • the power cable to an external energy supply can be dispensed with, which allows a greater range of movement of the tillage implement. This makes it possible, for example, to use the soil treatment device to clean stairwells.
  • the at least one energy store is advantageously attached to the base part and/or to the guide part.
  • the at least one energy store is advantageously attached in a removable manner.
  • the energy store can be changed and a longer service life can be enabled. Furthermore, this makes it possible to remove the energy store and thus reduce the weight of the base part and/or the guide part if the soil tillage implement is connected to an external power supply, for example, so that the base part can be moved and guided more easily by means of the guide part.
  • the base part has a loosely suspended splash guard, which can be moved in height relative to the base part and which surrounds the tool for tilling the soil at least in sections.
  • the splash guard Due to the loose arrangement of the splash guard, which can be moved in height, it can always sit flat on the work surface, regardless of the movements of the base part, and thus avoid splashing water.
  • the bottom part has a liquid supply. This means that the soil tillage device can also be used for wet scrubbing.
  • the liquid is supplied centrally through the driver plates and the processing attachments. This ensures an even distribution of the liquid over a wide area.
  • a liquid tank for the liquid supply is advantageously provided.
  • the tillage implement does not have to be connected to an external water supply, which would restrict the tillage implement's range of motion.
  • the liquid tank is advantageously attached to the base part or to the guide part above the further joint. As a result, the mobility of the base part is restricted as little as possible by means of the guide part.
  • the liquid tank attached to the guide part has an elongate shape along the guide part.

  • a container for the liquid taken up is arranged on the base part and/or on the guide part and is connected to the structurally separate suction unit via a hose.
  • the structural separation of the container for the liquid taken up from the suction turbine makes it possible to ensure in a simple manner that the suction turbine does not come into contact with liquid.
  • the provision of the container for the liquid taken up on the bottom part also has the advantage that the path for the water to be taken up from the floor into the container for the liquid taken up is as short as possible, which increases the effective suction power of the suction turbine.
  • the liquid receptacle has a squeegee with two sealing lips, which extends at least over half the width, preferably over the entire width of the base part and is bent around the tool for soil cultivation and extends transversely to the direction of cultivation and seen in the direction of movement behind the tool for soil cultivation is, wherein preferably the front sealing lip in the direction of movement is corrugated or has openings.
  • the squeegee with the sealing lips allows the liquid to be picked up directly. The further the squeegee with the sealing lips extends around the tillage tool, the more liquid is picked up in the first tillage operation. The ribbing or the openings in the front sealing lip allow the liquid to reach the area of the squeegee between the sealing lips and be sucked off there.
  • the squeegee with the sealing lips of the liquid receptacle is mounted loosely and movably in height relative to the base part.
  • the squeegee with the sealing lips is attached independently of the vertical movements of the base part, it can be ensured that the sealing lips are always seated on the processing surface, so that efficient liquid absorption is made possible.

Description

Technisches Gebiettechnical field

Die Erfindung betrifft ein handgeführtes Bodenbearbeitungsgerät zur Bearbeitung von Böden durch Schrubben, Polieren oder Schleifen.The invention relates to a hand-held floor preparation device for processing floors by scrubbing, polishing or grinding.

Stand der TechnikState of the art

Aus der EP 0 978 249 ist eine Vorrichtung zur Behandlung von Oberflächen bekannt, insbesondere zum Reinigen und Polieren, die ein in mindestens zwei Richtungen bewegliches Gelenk zwischen einer Haltevorrichtung und dem Bodenteil vorsieht. Dieses Gelenk ermöglicht es dem Benutzer, durch Schrägstellen der Haltevorrichtung die Griffhöhe der persönlichen Größe des Benutzers anzugleichen und die Vorrichtung in Bearbeitungsrichtung vor und zurück zu bewegen, sowie seitliche Bewegungen mit der Vorrichtung auszuführen.From the EP 0 978 249 a device for the treatment of surfaces is known, in particular for cleaning and polishing, which provides a joint that can be moved in at least two directions between a holding device and the base part. This joint allows the user to adjust the handle height to the personal size of the user by tilting the holding device and to move the device back and forth in the processing direction, as well as to carry out lateral movements with the device.

Da das Gelenk seitlich am Bodenteil angeordnet ist und das Bodenteil hervorstehende Teile aufweist, ist die seitliche Beweglichkeit allerdings eingeschränkt.However, since the joint is arranged laterally on the base part and the base part has protruding parts, lateral mobility is restricted.

Aus der DE 203 02 630 U1 ist eine Dampfschrubbmaschine mit einem in Bearbeitungsrichtung gegenüber dem Bodenteil beweglichen Griffteil bekannt, die einen Wassertank, eine Wasserpumpe, einen Erhitzer und einen Dampfverteiler am Bodenteil aufweist. Als vorteilhafte Weiterbildung wird zum trockenen Reinigen eine ebenfalls am Bodenteil angebrachte Staubsaugereinheit umfassend einen Einsaugraum, eine Einsaugpumpe, einen Saugkanal und eine Einsaugöffnung offenbart.From the DE 203 02 630 U1 a steam scrubbing machine is known which has a handle part which can be moved relative to the base part in the working direction and which has a water tank, a water pump, a heater and a steam distributor on the base part. As an advantageous further development, a vacuum cleaner unit, which is also attached to the base part, is disclosed for dry cleaning, comprising an intake chamber, an intake pump, a suction channel and an intake opening.

Weiterhin sind Rücken-Staubsauger mit einer Rückeneinheit und einem Tragegestell bekannt, bei denen die Rückeneinheit zumindest eine Einsaugpumpe und einen Einsaugraum umfasst. Zur Erhöhung der Beweglichkeit kann auch ein Energiespeicher zur Energieversorgung der Pumpe in der Rückeneinheit vorgesehen sein.Furthermore, backpack vacuum cleaners with a back unit and a carrying frame are known, in which the back unit comprises at least one intake pump and one intake chamber. In order to increase mobility, an energy storage device for supplying energy to the pump can also be provided in the back unit.

Die DE 196 22 856 A1 offenbart ein von Hand geführtes Flächenschrubbgerät, das mindestens eine, vorzugsweise zwei Tellerbürsten, sowie mindestens eine Walzbürste aufweist, und das auf Rädern abgestützt bewegt wird. Weiterhin ist eine Absaugleiste vorgesehen, die vorzugsweise am hinteren Ende des Reinigungsgerätes angebracht ist, und die über einen Schlauch mit einem Aufnahmebehälter für Schmutzwasser verbunden ist. Ein Behälter für Reinigungsflüssigkeit ist ebenfalls an dem Flächenschrubbgerät angebracht.The DE 196 22 856 A1 discloses a hand-held surface scrubber having at least one, preferably two, disk brushes and at least one roller brush, and which is supported on wheels to move. Furthermore, a suction strip is provided, which is preferably attached to the rear end of the cleaning device and which is connected via a hose to a receptacle for dirty water. A cleaning fluid reservoir is also attached to the surface scrubber.

Dieses Flächenschrubbgerät hat allerdings den Nachteil, dass sein Gewicht durch die am Gerät selbst angebrachten Flüssigkeitsbehälter erhöht wird, und dass die Räder zwar ein leichtes Bewegen in linearer Richtung zulassen, aber keine wirkliche Beweglichkeit in seitlicher Richtung ermöglichen.However, this surface scrubber has the disadvantages that its weight is increased by the liquid containers attached to the device itself, and that the wheels allow easy movement in a linear direction but do not allow real mobility in a lateral direction.

Aus der EP 0 560 523 A2 ist eine Lippe für ein Wischgerät bekannt, die auf ihrer einen Seitenfläche Vorsprünge entlang ihrer Länge mit nicht hervorstehenden Räumen zwischen den Vorsprüngen aufweist, die sich vom unteren Rand nach oben erstrecken, wobei die andere Seitenfläche glatt ist. Wird diese Lippe mit ihrer glatten Seite über einen Boden bewegt, so bildet sie eine Abdichtung mit dem Boden, die kein Wasser durchlässt. Wird die Lippe mit der Vorsprünge aufweisenden Seitenfläche über den Boden bewegt, so kann Wasser durch die genannten Zwischenräume fließen. Dadurch kann eine Saugeinheit bestehend aus zwei entsprechenden Lippen in zwei Richtungen, vor und zurück, Wasser aufnehmen.From the EP 0 560 523 A2 a lip for a mop is known which has on one side surface thereof protrusions along its length with non-protruding spaces between the protrusions extending upwards from the lower edge, the other side surface being smooth. When this lip is moved over a floor with its smooth side, it forms a seal with the floor that does not let water through. If the lip with the side surface having projections is moved over the floor, water can flow through the gaps mentioned. This allows a suction unit consisting of two respective lips to absorb water in two directions, back and forth.

Aus der US 4 499 624 A ist ein handgeführtes Bodenbearbeitungsgerät in Form eines Poliergeräts zum Polieren von Oberflächen bekannt. Das bekannte Poliergerät weist ein Bodenteil mit einem Polierwerkzeug, ein Führungsteil mit einem Griffteil und eine Flüssigkeitszuführung auf. Das Führungsteil ist über ein Doppelgelenk mit orthogonal ausgerichteten Gelenkachsen mit dem Bodenteil verbunden. Das Polierwerkzeug weist gegenläufig drehende Walzen auf. Die Flüssigkeitszuführung ist in Form einer Sprühanordnung an dem Bodenteil angeordnet und erlaubt es, einen Sprühnebel auf die Walzen aufzusprühen.From the U.S.A. 4,499,624 a hand-held floor preparation device in the form of a polishing device for polishing surfaces is known. The well-known polishing device has a base part with a polishing tool, a guide part with a handle part and a liquid feed. The guide part is connected to the base part via a double joint with orthogonally aligned joint axes. The polishing tool has counter-rotating rollers. The liquid supply is arranged in the form of a spray arrangement on the bottom part and allows a spray to be sprayed onto the rollers.

Der Erfindung liegt die Aufgabe zugrunde, ein Bodenbearbeitungsgerät bereitzustellen, welches neben Polieren oder Schleifen auch das Nassreinigen ermöglicht und dabei von Hand leicht beweglich und bedienbar ist.The invention is based on the object of providing a floor treatment device which, in addition to polishing or grinding, also enables wet cleaning and is easily movable and operable by hand.

Darstellung der ErfindungPresentation of the invention

Die Erfindung betrifft ein handgeführtes Bodenbearbeitungsgerät mit den Merkmalen des Anspruchs 1. Das Führungsteil weist am unteren Ende, unterhalb der Mitte, aber oberhalb des Bodenteils ein weiteres Gelenk mit einer quer zur ersten Gelenkachse verlaufenden weiteren Gelenkachse auf, um welche das Führungsteil quer zur Bearbeitungsrichtung derart verstellbar ist, dass das Bodenteil von einem Benutzer aus parallel zur Bearbeitungsfläche um eine Hochachse des Bodenteils um mindestens ±45° gedreht werden kann.The invention relates to a hand-held soil cultivation device with the features of claim 1. The guide part has at the lower end, below the center, but above the base part, a further joint with a further joint axis running transversely to the first joint axis, around which the guide part transversely to the working direction is adjustable in that the base part can be rotated by a user parallel to the working surface about a vertical axis of the base part by at least ±45°.

Das weitere Gelenk bildet mit dem ersten Gelenk ein Kardangelenk und ermöglicht es einem Benutzer, das Bodenteil innerhalb der Bearbeitungsebene zu drehen, auch wenn das Führungsteil um die erste Gelenkachse zu der Hochachse des Bodenteils schräg gestellt ist, was eine große Beweglichkeit des Bodenteils ermöglicht. So ist die Bearbeitungsrichtung des Bodenteils auch bei schräg gestelltem Führungsteil parallel zum Boden schwenkbar und ermöglicht das einfache Bearbeiten von Ecken oder Nischen oder unter Vorsprüngen.The other joint forms a cardan joint with the first joint and allows a user to rotate the base part within the working plane, even if the guide part is inclined about the first joint axis to the vertical axis of the base part, which allows the base part to be very mobile. The working direction of the floor part can be swiveled parallel to the floor, even when the guide part is at an angle, and allows easy working in corners or niches or under projections.

Prinzipiell ist mittels eines solchen Kardangelenks auch bei schräg gestelltem Führungsteil ein beliebiges Verdrehen des Bodenteils um seine Hochachse möglich. Vorteilhafterweise kann das Bodenteil vom Benutzer aus parallel zur Bearbeitungsfläche um die Hochachse des Bodenteils um mindestens ±270° gedreht werden.In principle, any rotation of the bottom part about its vertical axis is possible by means of such a cardan joint, even when the guide part is set at an angle. Advantageously, the user can rotate the base part by at least ±270° parallel to the working surface about the vertical axis of the base part.

Dies ermöglicht es dem Benutzer, das Bodenbearbeitungsgerät erst in einer von dem Benutzer weg zeigenden Richtung zu betreiben, dann das Bodenteil um 180° zu drehen und das Bodenbearbeitungsgerät in eine auf den Benutzer hin zeigende Richtung zurück zu bewegen. Weiterhin kann der Benutzer das Bodenteil, während er es wieder zu sich hin bewegt, auch noch weiter drehen, hat also auch bei auf den Benutzer zu gerichteter Bewegung des Bodenteils weiterhin die volle Beweglichkeit in seitlicher Richtung. Diese Beweglichkeit ermöglicht ein einfaches Reinigen von Ecken, Nischen oder Vorsprüngen, beispielsweise unter Treppen oder Tischen. Weiterhin ermöglicht die Beweglichkeit das Reinigen sowohl in Vorwärts- und Rückwärtsrichtung, als auch in seitlicher Richtung, auch wenn das Führungsteil um die erste Gelenkachse zu der Hochachse des Bodenteils schräg gestellt ist, wobei das Bodenbearbeitungsgerät immer in Bearbeitungsrichtung bewegt werden kann, was eine Voraussetzung für eine reguläre Aufnahme der Flüssigkeit darstellt.This enables the user to first operate the tillage implement in a direction pointing away from the user, then rotate the base part through 180° and move the tillage implement back in a direction pointing towards the user. Furthermore, the user can rotate the base part even further while moving it towards him again, so that he still has full mobility in the lateral direction even when the base part is moved towards the user. This mobility enables easy cleaning of corners, niches or projections, for example under stairs or tables. Furthermore, the mobility enables cleaning both in the forward and backward direction, as well as in the lateral direction, even if the guide part is inclined about the first joint axis to the vertical axis of the base part, whereby the soil tillage implement can always be moved in the tillage direction, which is a prerequisite for represents a regular intake of the liquid.

Vorteilhafterweise stützt sich das Bodenteil ausschließlich auf dem Werkzeug für die Bodenbearbeitung ab. Dadurch wird die Beweglichkeit des Bodenteils nicht durch eine Stützvorrichtung eingeschränkt.Advantageously, the base part is supported exclusively on the tool for tilling the soil. As a result, the mobility of the base part is not restricted by a support device.

Erfindungsgemäß besteht das Werkzeug für die Bodenbearbeitung aus mindestens zwei sich gegenläufig und im Wesentlichen horizontal drehenden Treibtellern mit Bearbeitungsaufsätzen.According to the invention, the tool for tilling the soil consists of at least two counter-rotating and substantially horizontally rotating drive plates with tillage attachments.

Die Gegenläufigkeit von jeweils zwei symmetrisch um die Mitte des Bodenbearbeitungsgeräts angebrachten Treibtellern führt bei einer geraden Anzahl von Treibtellern zu einem kräfteneutralen Zustand des Bodenteils und ermöglicht eine leichte, widerstandfreie Führbarkeit des Bodenteils mittels des Führungsteils über den Boden. Entsprechendes gilt auch für Walzen.The counter-rotation of two symmetrically attached driving discs around the center of the tillage implement results in an even number of driving discs in a force-neutral state of the base part and enables the base part to be guided easily and without resistance over the ground by means of the guide part. The same applies to rollers.

Vorteilhafterweise können die Bearbeitungsaufsätze Bürsten, Teller für Pads oder Schleifscheiben sein.Advantageously, the processing attachments can be brushes, discs for pads or grinding wheels.

Dadurch kann das Bodenbearbeitungsgerät für verschiedenste Arbeiten wie Polieren, Schrubben oder Schleifen eingesetzt werden.This means that the soil tillage device can be used for a wide variety of jobs such as polishing, scrubbing or grinding.

Vorteilhafterweise weist das Bodenbearbeitungsgerät zur Versorgung des Werkzeugs mindestens einen Energiespeicher und/oder ein Leistungskabel zu einer externen Energieversorgung auf.Advantageously, the soil cultivation device has at least one energy store and/or a power cable to an external energy supply to supply the tool.

Durch das Anschließen des Bodenbearbeitungsgeräts an eine externe Energieversorgung mittels eines Leistungskabels ist eine unbegrenzte Betriebsdauer möglich. Weiterhin kann dadurch das Gewicht des Bodenteils gering gehalten werden, was es dem Benutzer ermöglicht, das Bodenteil mittels des Führungsteils leicht zu bewegen und zu führen. Durch einen an dem Bodenbearbeitungsgerät angebrachten Energiespeicher kann auf das Leistungskabel zu einer externen Energieversorgung verzichtet werden, wodurch ein höherer Bewegungsradius des Bodenbearbeitungsgeräts ermöglicht wird. Dies macht es beispielsweise möglich, dass Bodenbearbeitungsgerät zum Reinigen von Treppenhäusern einzusetzen.By connecting the tillage implement to an external power supply using a power cable, an unlimited operating time is possible. Furthermore, the weight of the base part can thereby be kept low, which enables the user to easily move and guide the base part by means of the guide part. By means of an energy store attached to the tillage implement the power cable to an external energy supply can be dispensed with, which allows a greater range of movement of the tillage implement. This makes it possible, for example, to use the soil treatment device to clean stairwells.

Vorteilhafterweise ist der mindestens eine Energiespeicher am Bodenteil und/oder am Führungsteil angebracht.The at least one energy store is advantageously attached to the base part and/or to the guide part.

Vorteilhafterweise ist der mindestens eine Energiespeicher abnehmbar angebracht.The at least one energy store is advantageously attached in a removable manner.

Dadurch kann der Energiespeicher gewechselt und eine längere Betriebsdauer ermöglicht werden. Weiterhin ist es dadurch möglich, den Energiespeicher zu entfernen und damit das Gewicht des Bodenteils und/oder des Führungsteils zu verringern, wenn das Bodenbearbeitungsgerät beispielsweise an eine externe Energieversorgung angeschlossen ist, so dass das Bodenteil leichter mittels des Führungsteils bewegt und geführt werden kann.As a result, the energy store can be changed and a longer service life can be enabled. Furthermore, this makes it possible to remove the energy store and thus reduce the weight of the base part and/or the guide part if the soil tillage implement is connected to an external power supply, for example, so that the base part can be moved and guided more easily by means of the guide part.

Vorteilhafterweise weist das Bodenteil einen lose aufgehängten, in der Höhe gegenüber dem Bodenteil beweglichen Spritzschutz auf, welcher das Werkzeug für die Bodenbearbeitung zumindest abschnittsweise umgibt.Advantageously, the base part has a loosely suspended splash guard, which can be moved in height relative to the base part and which surrounds the tool for tilling the soil at least in sections.

Durch das lose, in der Höhe bewegliche Anordnen des Spritzschutzes kann dieser unabhängig von den Bewegungen des Bodenteils immer eben auf der Bearbeitungsfläche aufsitzen und so Spritzwasser vermeiden.Due to the loose arrangement of the splash guard, which can be moved in height, it can always sit flat on the work surface, regardless of the movements of the base part, and thus avoid splashing water.

Erfindungsgemäß weist das Bodenteil eine Flüssigkeitszuführung auf. Dadurch kann das Bodenbearbeitungsgerät auch zum Nassschrubben eingesetzt werden.According to the invention, the bottom part has a liquid supply. This means that the soil tillage device can also be used for wet scrubbing.

Erfindungsgemäß erfolgt die Flüssigkeitszuführung mittig durch die Treibteller und die Bearbeitungsaufsätze hindurch. Dies gewährleistet eine gleichmäßige flächige Verteilung der Flüssigkeit.According to the invention, the liquid is supplied centrally through the driver plates and the processing attachments. This ensures an even distribution of the liquid over a wide area.

Vorteilhafterweise ist ein Flüssigkeitstank für die Flüssigkeitszuführung vorgesehen. Dadurch muss das Bodenbearbeitungsgerät nicht an eine externe Wasserversorgung angeschlossen werden, was den Bewegungsradius des Bodenbearbeitungsgeräts einschränken würde.A liquid tank for the liquid supply is advantageously provided. As a result, the tillage implement does not have to be connected to an external water supply, which would restrict the tillage implement's range of motion.

Vorteilhafterweise ist der Flüssigkeitstank an dem Bodenteil oder an dem Führungsteil oberhalb des weiteren Gelenks angebracht. Dadurch wird die Beweglichkeit des Bodenteils mittels des Führungsteils möglichst wenig eingeschränkt.The liquid tank is advantageously attached to the base part or to the guide part above the further joint. As a result, the mobility of the base part is restricted as little as possible by means of the guide part.

Vorteilhafterweise ist der an dem Führungsteil angebrachte Flüssigkeitstank entlang des Führungsteils länglich ausgeformt. Dadurch befindet sich die Flüssigkeit möglichst nah am Führungsteil, so dass das Gewicht der Flüssigkeit das Bewegen des Führungsteils möglichst wenig erschwert.Advantageously, the liquid tank attached to the guide part has an elongate shape along the guide part. As a result, the liquid is as close as possible to the guide part, so that the weight of the liquid makes it as little difficult as possible to move the guide part.

Vorteilhafterweise ist der Behälter für die aufgenommene Flüssigkeit an dem Führungsteil oberhalb des weiteren Gelenks angebracht und länglich entlang des Führungsteils ausgeformt.Advantageously, the container for the received liquid is attached to the guide part above the further joint and is shaped longitudinally along the guide part.

Dadurch wird die durch die zwei Gelenke ermöglichte Beweglichkeit des Bodenteils nicht eingeschränkt und die Beweglichkeit des Führungsteils durch das Gewicht der aufgenommenen Flüssigkeit möglichst wenig belastet.As a result, the mobility of the base part made possible by the two joints is not restricted and the mobility of the guide part is burdened as little as possible by the weight of the liquid taken up.

Vorteilhafterweise weist das Bodenbearbeitungsgerät eine Flüssigkeitsaufnahme und eine baulich getrennte Saugeinheit auf, die zumindest eine Saugturbine für die Aufnahme der Flüssigkeit enthält. Durch die bauliche Trennung der Saugeinheit kann das Gewicht des Bodenteils und des Führungsteils gering gehalten werden, so dass das Bodenteil mittels Führungsteil leicht bewegt und geführt werden kann.Advantageously, the soil treatment device has a liquid receptacle and a structurally separate suction unit that contains at least one suction turbine for receiving the liquid. Due to the structural separation of the suction unit, the weight of the base part and the guide part can be kept low, so that the base part can be easily moved and guided by means of the guide part.

Vorteilhafterweise ist ein Behälter für die aufgenommene Flüssigkeit am Bodenteil und/oder am Führungsteil angeordnet und über einen Schlauch mit der baulich getrennten Saugeinheit verbunden.Advantageously, a container for the liquid taken up is arranged on the base part and/or on the guide part and is connected to the structurally separate suction unit via a hose.

Durch die bauliche Trennung des Behälters für die aufgenommene Flüssigkeit von der Saugturbine kann auf einfache Weise sichergestellt werden, dass die Saugturbine nicht mit Flüssigkeit in Kontakt kommt. Das Vorsehen des Behälters für die aufgenommene Flüssigkeit am Bodenteil hat weiterhin den Vorteil, dass der Weg für das aufzunehmende Wasser vom Boden in den Behälter für die aufgenommene Flüssigkeit möglichst kurz ist, wodurch sich die effektive Saugleistung der Saugturbine erhöht.The structural separation of the container for the liquid taken up from the suction turbine makes it possible to ensure in a simple manner that the suction turbine does not come into contact with liquid. The provision of the container for the liquid taken up on the bottom part also has the advantage that the path for the water to be taken up from the floor into the container for the liquid taken up is as short as possible, which increases the effective suction power of the suction turbine.

Vorteilhafterweise weist die Flüssigkeitsaufnahme eine Saugleiste mit zwei Dichtlippen auf, die sich mindestens über die halbe Breite, vorzugsweise über die ganze Breite des Bodenteils und um das Werkzeug für die Bodenbearbeitung herum gebogen quer zur Bearbeitungsrichtung erstreckt und in Bewegungsrichtung gesehen hinter dem Werkzeug für die Bodenbearbeitung angeordnet ist, wobei vorzugsweise die in Bewegungsrichtung vordere Dichtlippe geriffelt ist oder Öffnungen aufweist.Advantageously, the liquid receptacle has a squeegee with two sealing lips, which extends at least over half the width, preferably over the entire width of the base part and is bent around the tool for soil cultivation and extends transversely to the direction of cultivation and seen in the direction of movement behind the tool for soil cultivation is, wherein preferably the front sealing lip in the direction of movement is corrugated or has openings.

Die Saugleiste mit den Dichtlippen ermöglicht das direkte Aufnehmen der Flüssigkeit. Je weiter die Saugleiste mit den Dichtlippen um das Werkzeug zur Bodenbearbeitung herum reicht, desto mehr Flüssigkeit wird schon im ersten Bearbeitungsvorgang aufgenommen. Die Riffelung oder die Öffnungen der vorderen Dichtlippe ermöglichen, dass die Flüssigkeit in den Bereich der Saugleiste zwischen den Dichtlippen gelangt und dort abgesaugt wird.The squeegee with the sealing lips allows the liquid to be picked up directly. The further the squeegee with the sealing lips extends around the tillage tool, the more liquid is picked up in the first tillage operation. The ribbing or the openings in the front sealing lip allow the liquid to reach the area of the squeegee between the sealing lips and be sucked off there.

Vorteilhafterweise ist die Saugleiste mit den Dichtlippen der Flüssigkeitsaufnahme lose, in der Höhe gegenüber dem Bodenteil beweglich angebracht.Advantageously, the squeegee with the sealing lips of the liquid receptacle is mounted loosely and movably in height relative to the base part.

Dadurch dass die Saugleiste mit den Dichtlippen unabhängig von den vertikalen Bewegungen des Bodenteils angebracht ist, kann gewährleistet werden, dass die Dichtlippen immer auf der Bearbeitungsfläche aufsitzen, so dass eine effiziente Flüssigkeitsaufnahme ermöglicht wird. Ist der Spritzschutz entsprechend lose und gegenüber den vertikalen Bewegungen des Bodenteils unabhängig angeordnet, so ist es beispielsweise möglich, die Saugleiste mit den Dichtlippen am Spritzschutz anzubringen.Because the squeegee with the sealing lips is attached independently of the vertical movements of the base part, it can be ensured that the sealing lips are always seated on the processing surface, so that efficient liquid absorption is made possible. Is the splash guard appropriately loose and opposite arranged independently of the vertical movements of the floor part, it is possible, for example, to attach the squeegee with the sealing lips to the splash guard.

Ausführungsbeispielexample

In der Fig. 1 ist ein erfindungsmäßiges Bodenbearbeitungsgerät dargestellt. Ein Bodenteil 1 kann über ein Führungsteil 2 und ein Griffteil 3 von einem Benutzer P geführt werden, wobei das Führungsteil 2 mit dem Bodenteil 1 über zwei Gelenke verbunden ist, die zusammen ein Kardangelenk bilden. Ein erstes Gelenk 4 besteht aus einem Bügel 5 und einer in Fig. 3 dargestellten, am Bodenteil 1 angebrachten Achse 30, wobei eine Gelenkachse G1, die in Fig. 3 dargestellt ist, entlang der Achse 30 parallel zu einer Bearbeitungsfläche B und quer zur Bearbeitungsrichtung 6 verläuft und der Bügel 5 entsprechend der durch den Pfeil 7 angezeigten Richtung um die Achse G1 bewegt werden kann. Ein zweites Gelenk 8 verbindet das Führungsteil 2 mit dem Bügel 5, wobei eine Gelenkachse G2 quer zur Gelenkachse G1 verläuft und das Führungsteil um die Achse G2 entsprechend der durch den Pfeil 9 angezeigten Richtung bewegt werden kann. Dies ermöglicht es dem Benutzer P, auch bei schräg gestelltem Führungsteil 2 das Bodenteil 1 parallel zur Bearbeitungsfläche B um seine Hochachse A1 zu drehen. Damit kann der Benutzer P die Bearbeitungsrichtung 6 parallel zur Bearbeitungsfläche B drehen. Der Benutzer P kann das Bodenteil beispielsweise zuerst von sich weg und dann nach einem Drehen des Bodenteils um 180° auf sich zu bewegen, wobei die Bearbeitungsrichtung 6 entsprechend erst von ihm weg und dann auf ihn zu läuft.In the 1 a tillage implement according to the invention is shown. A base part 1 can be guided by a user P via a guide part 2 and a handle part 3, the guide part 2 being connected to the base part 1 via two joints which together form a cardan joint. A first joint 4 consists of a bracket 5 and an in 3 shown, attached to the bottom part 1 axis 30, wherein a hinge axis G1, the in 3 as shown, along the axis 30 parallel to a machining surface B and transverse to the machining direction 6, and the stirrup 5 can be moved about the axis G1 in the direction indicated by the arrow 7. A second joint 8 connects the guide part 2 to the bracket 5, with a joint axis G2 transverse to the joint axis G1 and the guide part being movable about the axis G2 according to the direction indicated by the arrow 9. This enables the user P to turn the base part 1 parallel to the working surface B about its vertical axis A1 even when the guide part 2 is in an inclined position. The user P can thus rotate the processing direction 6 parallel to the processing surface B. The user P can, for example, first move the bottom part away from him and then towards him after rotating the bottom part by 180°, with the processing direction 6 correspondingly first moving away from him and then towards him.

Das erfindungsgemäße Bodenbearbeitungsgerät weist einen Flüssigkeitstank 10 für die Flüssigkeitszuführung auf, der beispielsweise oberhalb des zweiten Gelenks 8 am Führungsteil 2 angebracht sein kann und über eine Flüssigkeitszuführung 11 mit dem Bodenteil 1 verbunden ist.The soil cultivation device according to the invention has a liquid tank 10 for the liquid supply, for example, above the second joint 8 on Guide part 2 can be attached and is connected to the base part 1 via a liquid supply 11 .

Bei der dargestellten Ausführungsform ist es vorteilhaft, den Flüssigkeitstank 10 so zu gestalten, dass er zumindest teilweise um das Führungsteil 2 herum reicht und seine Ausmaße in der Richtung quer zum Führungsteil 2 möglichst gering sind, während die Ausmaße entlang des Führungsteils 2 größer sein können. Dadurch wird das Bewegen des Führungsteils 2 möglichst wenig durch die sich im Flüssigkeitstank 10 ebenfalls bewegende Flüssigkeit erschwert.In the illustrated embodiment, it is advantageous to design the liquid tank 10 in such a way that it reaches at least partially around the guide part 2 and its dimensions in the direction transverse to the guide part 2 are as small as possible, while the dimensions along the guide part 2 can be larger. As a result, moving the guide part 2 is made more difficult as little as possible by the liquid also moving in the liquid tank 10 .

Das Bodenbearbeitungsgerät weist einen Spritzschutz 12 auf, der außenseitig am Bodenteil 1 angeordnet ist und möglichst weit um das Bodenteil 1 herumreicht. Der Spritzschutz 12 weist zur Bearbeitungsfläche B hin Borsten oder Lippen auf und ist so angeordnet, dass er in seiner Höhe über der Bearbeitungsfläche B gegenüber dem Bodenteil 1 beweglich ist, so dass er mit seinen Borsten oder Lippen immer auf der Bearbeitungsfläche B aufsitzt.The soil cultivation device has a splash guard 12 which is arranged on the outside of the base part 1 and extends as far as possible around the base part 1 . The splash guard 12 has bristles or lips towards the working surface B and is arranged in such a way that its height above the working surface B can be moved relative to the bottom part 1 so that its bristles or lips are always seated on the working surface B.

Weiterhin weist das Bodenteil 1 an seiner Unterseite eine Flüssigkeitsaufnahme 13 auf, die quer zur Bearbeitungsrichtung 6 möglichst weit über die Breite des Bodenteils 1 reicht und in Bewegungsrichtung 6 hinter dem Bodenteil 1 angeordnet und am Spritzschutz 12 befestigt ist, ohne die in der Höhe freie Beweglichkeit des Spritzschutzes 12 gegenüber dem Bodenteil 1 einzuschränken.Furthermore, the bottom part 1 has a liquid receptacle 13 on its underside, which extends as far as possible across the width of the bottom part 1 transversely to the processing direction 6 and is arranged behind the bottom part 1 in the direction of movement 6 and is attached to the splash guard 12, without being able to move freely in height of the splash guard 12 in relation to the base part 1.

Die baulich getrennte Saugeinheit ist in dem dargestellten Ausführungsbeispiel als eine von einem Benutzer P am Körper zu befestigende Einheit 15 ausgebildet. Diese am Körper zu befestigende Einheit 15 ist weiterhin als Rückeneinheit ausgebildet und über einen Schlauch 14 mit der Flüssigkeitsaufnahme 13 verbunden. Die Rückeneinheit 15 weist einen Behälter 16 für die von der Bodenfläche B aufgenommene Flüssigkeit sowie eine Saugturbine 17 auf, die mit einem Motor 18 angetrieben werden kann, der ebenfalls in der Rückeneinheit 15 angeordnet ist. Zur Energieversorgung ist der Motor 18 über ein Leistungs- und gegebenenfalls auch über ein Steuerkabel 19 direkt an das Bodenteil 1 angeschlossen, wobei ein Anschluss am Rückenteil 15 oder am Bodenteil 1 vorgesehen sein kann, so dass diese Verbindung zwischen Rückenteil 15 und Bodenteil 1 gelöst werden kann.In the exemplary embodiment shown, the structurally separate suction unit is designed as a unit 15 to be attached by a user P to the body. This unit 15 to be fastened to the body is also designed as a back unit and is connected to the liquid receptacle 13 via a hose 14 . The back unit 15 has a container 16 for the liquid taken up from the bottom surface B and a suction turbine 17 which can be driven by a motor 18 which is also arranged in the back unit 15 . For the power supply, the motor 18 is connected directly to the base part 1 via a power cable and optionally also via a control cable 19, with a connection being able to be provided on the back part 15 or on the base part 1, so that this connection between the back part 15 and the base part 1 can be released can.

In einer weiteren Ausführungsvariante kann das Leistungs- und Steuerkabel 19 auch über das Griffteil 3 und/oder das Führungsteil zum Bodenteil 1 geführt werden, oder es kann ein Anschluss am Griffteil 3 oder am Führungsteil 2 vorgesehen sein, an den das Leistungs- und Steuerkabel 19 angeschlossen werden kann.In a further embodiment variant, the power and control cable 19 can also be routed via the handle part 3 and/or the guide part to the base part 1, or a connection can be provided on the handle part 3 or on the guide part 2, to which the power and control cable 19 can be connected.

Es kann auch vorteilhaft sein, den Behälter 16 für die von der Bodenfläche B aufgenommene Flüssigkeit beispielsweise an dem Führungsteil 2 anzuordnen und über je einen Schlauch mit der Flüssigkeitsaufnahme 13 und der Saugturbine 17 zu verbinden, da so ein sehr kurzer Saugweg möglich ist, wodurch sich die effektive Saugleistung der Saugturbine 17 verbessert. Hierbei ist es vorteilhaft, den Behälter 16 für die aufgenommene Flüssigkeit länglich entlang des Führungsteils 2 auszuformen, so dass sich die aufgenommene Flüssigkeit immer möglichst nah an dem Führungsteil 2 befindet und dadurch die Beweglichkeit des Führungsteils 2 nicht unnötig durch das Gewicht der aufgenommenen Flüssigkeit belastet wird.It can also be advantageous to arrange the container 16 for the liquid picked up from the bottom surface B, for example on the guide part 2, and to connect it to the liquid holder 13 and the suction turbine 17 via a hose each, since this allows for a very short suction path, which the effective suction power of the Improved suction turbine 17. It is advantageous here to shape the container 16 for the absorbed liquid longitudinally along the guide part 2 so that the absorbed liquid is always as close as possible to the guide part 2 and the mobility of the guide part 2 is therefore not unnecessarily burdened by the weight of the absorbed liquid .

Dadurch, dass sowohl der Flüssigkeitstank für die Flüssigkeitszuführung als auch der Behälter 16 für die aufgenommene Flüssigkeit am Führungsteil 2 und/oder am Bodenteil 1 angeordnet werden, bleibt das Gesamtgewicht der Bodeneinheit aus Bodenteil 1 und Führungsteil 2 während der Bodenbearbeitung im Wesentlichen konstant. Dies ermöglicht es, den Druck auf das mindestens eine Werkzeug 31 zur Bodenbearbeitung konstant zu halten und so eine konstante und zuverlässige Funktionsweise zu garantieren.Due to the fact that both the liquid tank for the liquid supply and the container 16 for the received liquid are arranged on the guide part 2 and/or on the base part 1, the total weight of the base unit made up of base part 1 and guide part 2 remains essentially constant during soil cultivation. This makes it possible to keep the pressure on the at least one tillage tool 31 constant and thus to guarantee constant and reliable functioning.

Weiterhin ist es möglich, den Behälter für die aufgenommene Flüssigkeit und den Flüssigkeitstank für die Flüssigkeitszuführung gleich auszuformen, also nur eine Form für beide Behälter zu wählen, wodurch die Produktionskosten des Bodenbearbeitungsgeräts verringert werden können.Furthermore, it is possible to shape the container for the received liquid and the liquid tank for the liquid supply in the same way, ie to select only one shape for both containers, whereby the production costs of the soil tillage implement can be reduced.

Weiterhin hat das Vorsehen des Behälters 16 für die aufgenommene Flüssigkeit am Bodenteil 1 und/oder am Führungsteil 2 den Vorteil, dass beim Lösen des Schlauchs, der den Behälter 16 für die aufgenommene Flüssigkeit mit der Saugturbine 17 verbindet, keine im Schlauch verbliebene Restflüssigkeit auslaufen kann, da die Flüssigkeit in dem tiefer liegenden Behälter 16 für die aufgenommene Flüssigkeit verbleibt.Furthermore, the provision of the container 16 for the collected liquid on the base part 1 and/or on the guide part 2 has the advantage that when the hose that connects the container 16 for the collected liquid with the suction turbine 17 is detached, no residual liquid remaining in the hose can escape , since the liquid remains in the lower-lying container 16 for the received liquid.

Die Rückeneinheit 15 weist ein Tragegestell 20 auf, wodurch es von dem Benutzer P komfortabel auf dem Rücken getragen werden kann.The back unit 15 has a carrying frame 20, as a result of which the user P can comfortably carry it on his back.

Für andere Ausführungsformen der am Körper zu befestigenden Einheit 15 können entsprechend an die Art des Tragens angepasste Tragegestelle vorgesehen sein und auch die Form der am Körper zu befestigenden Einheit ist an die Art des Tragens anzupassen. Eine Rückeneinheit kann beispielsweise länglich flach ausgebildet werden und mit einem Rucksack-ähnlichen Tragegestell versehen werden. Soll die am Körper zu befestigende Einheit um die Hüfte getragen werden, muss sie entsprechend kleiner ausgebildet und mit einem Hüftgurt versehen werden. Eine vor dem Bauch zu befestigende Einheit kann beispielsweise nicht so lang ausgebildet werden, wie dies bei einer Rückeneinheit möglich ist.For other embodiments of the unit 15 to be attached to the body, carrying frames adapted to the type of wearing can be provided and the shape of the unit to be attached to the body can also be adapted to the type of wearing. A back unit can, for example, have an elongated, flat design and be provided with a carrying frame similar to a rucksack. If the unit to be attached to the body is to be worn around the waist, it must be made correspondingly smaller and fitted with a waist belt. For example, a front mount unit cannot be made as long as a back unit can be made.

In der Fig. 2 ist die Rückeneinheit aus Fig. 1 im Querschnitt dargestellt. Der Behälter 16 für die aufgenommene Flüssigkeit weist im Bodenbereich eine Auslassöffnung 21 auf, an die ein Auslassschlauch 22 oder auch ein Auslassstutzen mit einem Verschluss 23 angebracht ist. Der Auslassschlauch 22 und der Verschluss 23 sind so angeordnet, dass die Absperrarmatur 23 vom Benutzer P bedient und die aufgenommene Flüssigkeit aus dem Behälter 16 für die aufgenommene Flüssigkeit über den Ablassschlauch 22 abgelassen werden kann, während der Benutzer P die Rückeneinheit 15 auf dem Rücken trägt. Um die Bewegungsfreiheit des Benutzers P beim Ablassen der aufgenommenen Flüssigkeit zu erhöhen, kann für den Schlauch 14 ein Anschluss mit einer Kupplung vorgesehen sein, so dass diese Verbindung der Rückeneinheit 15 mit dem Bodenteil 1 gelöst werden kann. Alternativ kann auch ein Stutzen am Bodenteil 1 vorgesehen sein. Der Schlauch oder Stutzen am Bodenteil kann auch als Siphon ausgebildet sein, der verhindert, dass Restwasser ausläuft.In the 2 the back unit is off 1 shown in cross section. The container 16 for the received liquid has an outlet opening 21 in the bottom area, to which an outlet hose 22 or also an outlet socket with a closure 23 is attached. The discharge hose 22 and the cap 23 are arranged so that the shut-off fitting 23 is operated by the user P and the received liquid from the received liquid container 16 via the discharge hose 22 can be lowered while the user P carries the back unit 15 on his back. In order to increase the freedom of movement of the user P when draining the liquid taken up, a connection with a coupling can be provided for the hose 14 so that this connection of the back unit 15 to the base part 1 can be released. Alternatively, a socket can also be provided on the base part 1 . The hose or socket on the bottom part can also be designed as a siphon that prevents residual water from running out.

Die Rückeneinheit 15 weist in dieser Ausführungsvariante eine Energieversorgung 24 für den Motor 18 und eine Schalter 25 zum Ein- und Ausschalten der Saugturbine 17 auf.In this embodiment variant, the back unit 15 has an energy supply 24 for the motor 18 and a switch 25 for switching the suction turbine 17 on and off.

Weiterhin ist in der Fig. 2 das Bodenteil 1 des erfindungsmäßigen Bodenbearbeitungsgeräts von unten ohne einen Bearbeitungsaufsatz dargestellt. Durch einen Motor 26 werden zwei Treibteller 27 gegenläufig und im Wesentlichen horizontal angetrieben. Am Spritzschutz 12, der in dieser Ausführungsvariante ringförmig um das gesamte Bodenteil 1 herumreicht, ist die Flüssigkeitsaufnahme 13 so angebracht, dass die freie Bewegung des Spritzschutzes 12 in seiner Höhe über der Bearbeitungsfläche gegenüber dem Bodenteil 1 nicht beeinträchtigt ist. Die Flüssigkeitsaufnahme 13 weist eine Saugleiste 49 mit zwei in Bearbeitungsrichtung 6 zueinander beabstandeten Dichtlippen 28, 29 auf, wobei die in Bearbeitungsrichtung 6 vordere Lippe 28 möglichst geriffelt ist oder Öffnungen aufweist, durch welche beim Bewegen des Bodenteils 1 in Bearbeitungsrichtung 6 die aufzunehmende Flüssigkeit in den Bereich x zwischen den beiden Dichtlippen 28, 29 gelangen kann. Dieser Bereich x der Saugleiste 49 zwischen den Dichtlippen 28, 29 ist über den Schlauch 14 mit der als Rückeneinheit 15 ausgebildeten Saugeinheit verbunden, so dass Flüssigkeit aufgesaugt werden kann.Furthermore, in the 2 the bottom part 1 of the inventive tillage device shown from below without a processing attachment. A motor 26 drives two drive plates 27 in opposite directions and essentially horizontally. The liquid receptacle 13 is attached to the splash guard 12, which in this embodiment variant extends annularly around the entire base part 1, so that the free movement of the splash guard 12 in its height above the working surface in relation to the base part 1 is not impaired. The liquid receptacle 13 has a suction strip 49 with two sealing lips 28, 29 spaced apart from one another in the processing direction 6, with the front lip 28 in the processing direction 6 being corrugated as far as possible or having openings through which, when the base part 1 is moved in the processing direction 6, the liquid to be absorbed can flow into the Area x between the two sealing lips 28, 29 can reach. This area x of the squeegee 49 between the sealing lips 28, 29 is connected via the hose 14 to the suction unit designed as a back unit 15, so that liquid can be sucked up.

Die Fig. 3 zeigt einen Querschnitt des Bodenteils 1 mit Führungsteil 2 und Griffteil 3 des Bodenbearbeitungsgeräts aus Fig. 1. Dargestellt ist wieder das Gelenk 4, das aus dem Bügel 5 und der Achse 30, die am Bodenteil 1 befestigt ist, besteht, wobei das Gelenk 4 um die Gelenkachse G1 entsprechend der durch den Pfeil 7 angezeigten Richtung bewegt werden kann.The 3 shows a cross section of the base part 1 with the guide part 2 and the handle part 3 of the tillage implement 1 . Shown again is the joint 4 consisting of the bracket 5 and the axle 30 fixed to the bottom part 1, the joint 4 being able to move about the joint axis G1 according to the direction indicated by the arrow 7.

Weiterhin weist das Bodenteil 1 ein Werkzeug 31 für die Bodenbearbeitung auf, welches die Treibteller 27 und Bearbeitungsaufsätze 32 wie beispielsweise dargestellte Bürsten umfasst, wobei sich das Bodenteil 1 ausschließlich auf dem Werkzeug 31 abstützt. Die auf den Treibtellern 27 angeordneten Bearbeitungsaufsätze 32 werden mit dem Motor 26 angetrieben, der durch einen Energiespeicher 33 versorgt wird. Dieser Energiespeicher 33 ist möglichst abnehmbar am Bodenteil 1 befestigt und kann beispielsweise über ein Leistungskabel aufgeladen werden. Der Motor 26 weist möglichst ebenfalls ein Leistungskabel 35 auf, was es ermöglicht, auf den Energiespeicher 33 zu verzichten und den Motor 26 an eine externe Energieversorgung anzuschließen.Furthermore, the base part 1 has a tool 31 for tilling the soil, which includes the driving plate 27 and processing attachments 32 such as brushes shown, for example, with the base part 1 being supported exclusively on the tool 31 . The processing attachments 32 arranged on the driving plates 27 are driven by the motor 26 which is supplied by an energy store 33 . This energy store 33 is fastened to the base part 1 in a detachable manner, if possible, and can be charged, for example, via a power cable. If possible, the motor 26 also has a power cable 35, which makes it possible to dispense with the energy store 33 and to connect the motor 26 to an external energy supply.

Die Flüssigkeitszuführung 11 der Flüssigkeit aus dem Flüssigkeitstank 10 erfolgt mittig durch die Treibteller 27 hindurch.The liquid is supplied 11 from the liquid tank 10 centrally through the drive plate 27 .

Der Spritzschutz 12 kann mit mindestens einem über das Bodenteil 1 reichenden Bügel 36 lose mit dem Bodenteil 1 verbunden sein, so dass er während des Bearbeitens in der Höhe, also in der Richtung des Pfeils 37, frei beweglich ist, aber beim Anheben des Bodenteils 1 über den mindestens einen Bügel 36 mit dem Bodenteil 1 verbunden bleibt. Dadurch kann der Benutzer P das Bodenteil 1 und den Spritzschutz 12 gleichzeitig anheben und versetzen und muss den Spritzschutz 12 nicht noch zusätzlich bewegen.The splash guard 12 can be loosely connected to the base part 1 with at least one bracket 36 reaching over the base part 1, so that it can be freely moved in height during processing, i.e. in the direction of the arrow 37, but when the base part 1 is raised remains connected to the base part 1 via the at least one bracket 36 . As a result, the user P can lift and move the base part 1 and the splash guard 12 at the same time and does not have to move the splash guard 12 in addition.

Der Energiespeicher zur Versorgung des die Saugturbine antreibenden Motors kann auch am Führungsteil angeordnet werden, wobei der Energiespeicher vorteilhafterweise unterhalb des Tanks 19, aber oberhalb des Gelenks 8 angebracht wird.The energy store for supplying the motor driving the suction turbine can also be arranged on the guide part, with the energy store advantageously being fitted below the tank 19 but above the joint 8 .

In Fig. 4 sind weiter Ausführungsvarianten des Werkzeugs 31 für die Bodenbearbeitung dargestellt. Die Fig. 4A zeigt einen Treibteller 27 mit einem Bearbeitungsaufsatz 32 in Form eines Tellers 48 für Pads 38, und in Fig. 4B ist ein Treibteller 27 mit einer Schleifscheibe 39 als Bearbeitungsaufsatz dargestellt.

Durch Drehen des Griffteils 3 um 90° um eine Längsachse A2 des Führungsteils 2 wird das Bodenteil ebenfalls um 90° um die Hochachse A1 gedreht, wobei der Bügel 5 dabei von einer gegen die erste Bearbeitungsrichtung 6 schräg gestellten Ausgangslage um die Achse G1 in eine Lage parallel zur Achse A1 gebracht wird und das Führungsteil 2 um die weitere Gelenkachse G2 von einer anfänglichen Ausrichtung parallel zu einer Längsachse A3 des Bügels 5 in eine Ausrichtung schräg zu der Längsachse A3 des Bügels 5 bewegt wird. Von dieser in Fig. 5 B dargestellten Lage aus kann das Bodenteil 1 durch Drehen des Griffteils 3 um weitere 90° ebenfalls um weitere 90° gedreht werden, so dass die Bearbeitungsrichtung 6, die ursprünglich in Richtung von dem Benutzer P weg zeigt, nun zu dem Benutzer P hin gerichtet ist, entsprechend der von Pfeil 6' angezeigten Richtung.In Figure 5A,B shows how the base part 1 of the soil cultivation device according to the invention can be rotated by means of the joints 4 and 8 about the vertical axis A1 of the base part 1, which is essentially perpendicular to the working surface B, when the guide part 2 is in an inclined position. By rotating the handle part 3 by 90° about a longitudinal axis A2 of the guide part 2, the base part is also rotated by 90° about the vertical axis A1, whereby the bracket 5 moves from an initial position inclined against the first processing direction 6 about the axis G1 into a position is brought parallel to the axis A1 and the guide part 2 is moved about the further hinge axis G2 from an initial alignment parallel to a longitudinal axis A3 of the bracket 5 to an alignment oblique to the longitudinal axis A3 of the bracket 5. From this in Figure 5B From the position shown, the base part 1 can also be rotated by a further 90° by rotating the grip part 3 by a further 90°, so that the processing direction 6, which originally points away from the user P, is now directed towards the user P. according to the direction indicated by arrow 6'.
