HAND-OPERATED FLOOR PROCESSING EQUIPMENT, SUPPLY UNIT FOR A HAND-OPERATED FLOOR PROCESSING EQUIPMENT, METHOD FOR MANUFACTURING A HAND-OPERATED FLOOR PROCESSING EQUIPMENT, AND METHOD FOR CLEANING A FLOOR WITH A HAND-OPERATED FLOOR PROCESSING EQUIPMENT

Description

[0001] The present invention relates to a hand-held soil cultivation implement, a supply unit for a hand-held soil cultivation implement, a method for manufacturing a hand-held soil cultivation implement, and a method for cleaning soil with a hand-held soil cultivation implement.

[0002] Hand-operated soil cultivation equipment, particularly cleaning equipment, is a device used by a user to cultivate soil. The user guides the equipment by hand, thereby cleaning the soil. Hand-operated soil cultivation equipment without a motor is known, as are motorized hand-operated versions. Hand-operated soil cultivation equipment without a motor is easy to use and versatile. However, the processing capacity, i.e., the area covered while maintaining consistent cleaning quality, is low for hand-operated soil cultivation equipment without a motor, as it quickly becomes saturated with dirt and merely redistributes it. Motorized hand-operated soil cultivation equipment offers higher processing capacity than hand-operated equipment without a motor.However, motorized handheld soil cultivation tools are often bulky and inflexible. Such tools often cannot be used under tables or other objects. This inflexibility results in low efficiency when a user operates a motorized handheld soil cultivation tool in spaces with obstacles (e.g., tables).

[0003] EP 0 648 462 A1 discloses a machine for processing surfaces.

[0004] GB 935 506 A discloses a cleaning device in which a cleaning fluid can be applied to a roller by means of a spray device.

[0005] US 5 381 578 A discloses a polishing machine with a processing pad.

[0006] EP 3 453 304 A1 discloses a cleaning device for cleaning surfaces. US2012 / 304408 A1 discloses a hand-held soil cultivation device.

[0007] The object of the invention is to overcome the disadvantages of the prior art and, in particular, to create a soil cultivation implement that exhibits high cleaning performance and is simultaneously flexible in its application. This object is achieved by a hand-held soil cultivation implement, a supply unit for a hand-held soil cultivation implement, a method for manufacturing a hand-held soil cultivation implement, and a method for cleaning soil with a hand-held soil cultivation implement according to the independent claims.

[0008] In particular, the task is solved by a hand-held soil cultivation implement. The hand-held soil cultivation implement comprises a soil section with at least one tool for soil cultivation, at least one motor for driving the tool, a guide handle, and a power supply unit.

[0009] The guide rod comprises a first section, a second section, and a third section. The first and third sections have longitudinal axes that are essentially parallel. The second section connects the first section to the third section.

[0010] Such a hand-operated soil cultivation device is flexible and efficient to use and can be used particularly in areas that are cramped or narrow or where there is furniture such as tables or similar.

[0011] According to the invention, "parallel" means that the axes are parallel but not coaxial, i.e., they do not share the same axis. The parallel axes are therefore spaced apart.

[0012] The soil assembly comprises one or more soil cultivation tools. These tools may be designed to clean, polish, or otherwise work the soil. The soil cultivation implement includes one or more motors to drive the tools. These can be electric motors, for example, but other types of motors may also be used.

[0013] The guide shaft can be made of plastic, metal, or another material. It can also be made of multiple materials or a composite material. The supply unit can be located on the guide shaft or elsewhere.

[0014] The longitudinal axis of the second section can be orthogonal to the longitudinal axis of the first section and the longitudinal axis of the third section. The angle between the longitudinal axis of the second section and the longitudinal axis of the first and / or third section can be in a range of 15° to 85° or 165° to 95°, in particular, the angle can be in a range of 35° or 155° or in a range of 45° or 145°.

[0015] The guide shaft of the hand-held soil cultivation implement can include a fourth and a fifth section. The fifth section can be arranged parallel to the first and third sections. The fifth section can be arranged coaxially with the first section. The fourth section can connect the fifth and third sections. The fourth section can be shorter than the second section.

[0016] Such a hand-held soil cultivation tool has a particularly user-friendly shape and can be used well for cultivating soil.

[0017] The fourth section can be connected to the third and fifth sections at an angle of 90° each. The angle between the longitudinal axis of the fourth section and the longitudinal axis of the fifth and / or third section can be in a range of 15° to 85° or 165° to 95°, respectively; in particular, the angle can be in a range of 35° or 155°, or in a range of 45° or 145°. The fourth section can be connected to the third and fifth sections at angles that are substantially the same as the angles at which the second section is connected to the first and third sections. The angles at which the second section is connected to the first and third sections and the angles at which the fourth section is connected to the third and fifth sections can be different.

[0018] The fourth section and / or the fifth section can be connected to the bottom part by a connection.

[0019] This allows the base section to be guided by movements of the guide handle and the area to be cleaned to be worked precisely.

[0020] The joint can be made of the same material as the stem. It can also be made of a different material. The joint can be rigid or hinged. The hinge can include elastic elements. It is also possible for the joint to have no elastic elements at all.

[0021] The guide shaft comprises at least one handle. The handle may be located on the first section and / or the third section of the guide shaft. The handle, or one of the handles, may be spherical or elliptical. A spherical handle may be located above the first section. The handle may also be cylindrical. The handle may have a longitudinal axis. The longitudinal axis of the handle may be identical to the longitudinal axis of the first section and / or the longitudinal axis of the third section of the guide shaft. The handle is rotatable about its longitudinal axis.

[0022] This type of handle makes the hand-held soil cultivator user-friendly and efficient to use. In particular, the soil cultivator is easy to handle and can be used flexibly and advantageously in confined or overgrown areas where precise guidance of the soil section is necessary.

[0023] The handle can be made of plastic, e.g., a thermoplastic. The handle can also be made of metal. The handle can have a non-slip surface. The handle can also be made of multiple materials or a composite material. The surface of the handle can be designed to be non-slip. The handle can be designed to rotate continuously around its longitudinal axis.

[0024] The joint of the hand-held tillage implement can include two adjustable joints. The joint axes of the two joints can essentially lie in the same plane and intersect. The joint axes of the two joints can intersect at right angles. It is also possible for the joint axes of the two joints to intersect at another angle. One joint axis can be aligned with the tillage direction of the implement, and the other joint axis can be aligned perpendicular to the tillage direction.

[0025] The flexible joint design of the base section on the guide handle allows it to be maneuvered around obstacles, such as table legs, much like a mop. This joint arrangement also enables access to hard-to-reach areas like niches and corners. The fact that the joint axes lie essentially on the same plane makes the joint particularly compact yet flexible. This allows for a space-saving design of the soil cultivation tool, enabling the user to work with it with minimal effort and for extended periods.

[0026] The joint axes can be arranged on different planes. The first joint axis can be positioned essentially perpendicular to the working direction of the tillage implement, either above or below the second joint axis.

[0027] A simple and quick movement of the soil cultivation implement, similar to wet cleaning with a mop, is made possible by this type of joint. The guide shaft can be connected to the base unit via two joints, with one joint positioned in a recess in the base unit so that its axis intersects the body of the base unit. The other joint can then be positioned above it. This arrangement makes the soil cultivation implement particularly compact. A supply hose can be routed through the upper joint and into the base unit alongside the lower joint. This minimizes mechanical stress on the supply hose, resulting in exceptional durability and low maintenance for the soil cultivation implement.

[0028] The first and second joints can be identical in structure. Alternatively, they can be differently structured.

[0029] The connection can include a ball joint. The ball joint can be at least partially surrounded by an elastic element. The elastic element allows the ball joint to be moved into a rest position.

[0030] A ball joint is uniformly movable in all directions and exhibits essentially the same friction or resistance in all directions of movement. Furthermore, a ball joint is particularly robust and insensitive to external mechanical influences such as impacts. If the ball joint is surrounded by an elastic element and can be returned to a rest position, it provides advantageous support for the user when positioning the soil part. This allows the user to work with the soil cultivation implement extremely comfortably and for extended periods.

[0031] The ball and socket of the ball joint can be made of the same material. They can also be made of different materials. The elastic element of the ball joint can be made of rubber, an elastomer, or another elastic material. The ball joint may also be surrounded by multiple elastic elements. It is possible that the ball joint is surrounded by a sleeve made of plastic, rubber, or another material. The sleeve may be secured by a spring.

[0032] The fifth section of the hand-held soil cultivation implement can be connected to the ground section by an elastic element. The fifth section of the hand-held soil cultivation implement can also be connected to the ground section by at least two elastic elements. The elastic element can have a rest position and a longitudinal axis. The elastic element can be curved from the rest position in a direction perpendicular to the longitudinal axis of the rest position.

[0033] The deformation properties of an elastic element can be predefined. This allows the movement behavior of the soil section to be advantageously influenced by the elastic element. By arranging at least two elastic elements, the movement behavior of the soil section can be influenced by the interaction of these two elements. This allows the soil cultivation implement to be designed particularly advantageously for operation by a single user. Furthermore, the elastic elements can be designed so that they are user-replaceable. New elastic elements can then be installed when the old ones are defective or worn out. This makes the soil cultivation implement quick and inexpensive to maintain.

[0034] The elastic element can comprise one or more materials. For example, the elastic element can be made of rubber or an elastomer. The elastic element can also include a spring. The elastic element can be designed as a hollow body or as a solid body. The longitudinal axis of the elastic element can essentially correspond to the longitudinal axis of the first section and / or the fifth section of the guide rod. The longitudinal axis of the elastic element can be parallel and spaced apart from the first section and / or the third section of the guide rod.

[0035] A supply unit may be arranged on the handle of the hand-held soil cultivation implement. The supply unit may be located on the third section of the handle. The supply unit may be detachably attached and / or detachably mounted. The supply unit includes a cleaning fluid tank and may also include a power supply unit and / or a dirty water tank and / or a pumping device and / or a suction device.

[0036] The supply unit provides a compact unit from which all consumables are supplied. Positioning the supply unit on the third section of the guide arm places its center of gravity close to the longitudinal axis of the first and / or fifth section of the guide arm. This results in an advantageous weight distribution, making the tillage implement extremely easy, flexible, and user-friendly. The detachable design of the supply unit allows for particularly simple removal from the arm, enabling transport on a trolley or carrying device.Because the cleaning fluid tank, power supply unit, wastewater tank, pump, and / or suction unit are centrally located in the supply unit, the soil cultivation machine can be designed to be extremely compact. Furthermore, maintenance and cleaning are particularly easy, as many parts requiring maintenance or cleaning are concentrated in the supply unit. This allows the supply unit, with its components, to be removed, and the components can be replaced, emptied, or recharged, for example, in a utility room.

[0037] The power supply unit can be designed to be attached and detached using or without tools. The power supply can be a battery, a rechargeable battery, or a mains connection. The power supply can be detachably integrated into the power supply unit or, in the case of a mains connection, designed as a cable. The cleaning fluid tank and / or the wastewater tank can be detachably arranged within the power supply unit.

[0038] The detachable design of the power supply allows for the operation of a tillage implement using at least two power sources, such as batteries, which can be used alternately. One power source can be located in the power supply unit while the other is being charged in a charging device. When the power source in the power supply unit runs low, the two power sources can be quickly and easily swapped. This allows the tillage implement to be operated with virtually no downtime. The progress and efficiency of the work are then primarily determined by the operator's stamina. Therefore, the tillage implement does not become the limiting factor in daily operations.

[0039] The power supply unit of the hand-held tillage implement can be connected to the working area via a supply line. The supply line can be located in the fifth section of the guide shaft.

[0040] The supply line allows the bottom section of the tillage implement to be efficiently supplied with energy and other media. By positioning the supply line in the fifth section of the guide arm, it is at least partially enclosed by other components. This protects the supply line from external mechanical influences. As a result, the supply line is advantageously positioned, requires minimal maintenance, and has a long service life.

[0041] The supply line can include one or more electrical conductors. The supply line can also include one or more control lines. The supply line can also include a fresh water line and / or a wastewater line. The supply line can be rigid or flexible. Sections of the supply line can be rigid, while other parts are flexible. It is also conceivable that the supply line contains additional electrical conductors and / or lines for media. The supply line can be located at least partially within a joint of the fifth section. The supply line can also be located entirely within a joint of the fifth section.

[0042] The supply unit may include a wastewater defoaming device. The wastewater defoaming device may be located in the wastewater tank of the supply unit. The wastewater defoaming device may have multiple lamellae.

[0043] This prevents or at least minimizes foam in the wastewater tank, thus reducing the space required for the wastewater tank.

[0044] The wastewater defoaming device can be made of plastic or metal. It can also be made of other materials, a combination of materials, or a composite material. The louvers can be designed so that the wastewater is introduced between them and guided by the curvature of the louvers. Advantageously, with a properly arranged wastewater tank and supply system, the louvers are open downwards, towards the bottom of the wastewater tank. Water trapped between the louvers is thus carried by gravity from the louvers to the bottom of the wastewater tank, while dry air can flow through the louvers into the exhaust duct.

[0045] The louvers can be designed so that, at the point where the wastewater impacts them, the longitudinal axis of the louvers is essentially parallel to the longitudinal axis of the wastewater jet. Advantageously, the louvers are beveled, so that the wastewater jet does not strike the louvers with its full cross-section, but must travel a certain distance before its entire cross-section impacts the louvers. Furthermore, the bevel ensures that larger dirt particles are conveyed more effectively, thus preventing blockages. The louvers can have multiple curves. The arrangement and shape of the louvers divide the wastewater jet into the spaces between them. Gravity then carries the divided wastewater jet, located between the louvers, to the bottom of the wastewater tank.The design of the wastewater defoaming device with its fins allows the wastewater entering the wastewater tank through the wastewater inlet to drip and slide gently into the wastewater already present in the tank. Without the defoaming device, the wastewater would enter the tank in a jet, resulting in significantly more foam. The defoaming device thus prevents or at least minimizes foaming.

[0046] A support device may be incorporated into the handle of the hand-held soil cultivation implement. The support device may be located in the third section of the handle. The support device may have a working position and a stationary position. The support device may be lowerable from the working position to the stationary position. The lowering movement may be linear.

[0047] The support device allows for advantageous stabilization of the hand-held soil cultivation implement. The support device can be designed so that a user can lower it with a foot or hand without bending over. This allows the user to move the support device from the working position to the standing position in a way that is easy on their back.

[0048] The support device can be made of plastic. It can also be made of metal or other materials. The support device can also comprise several materials. The support device can include wheels or casters, in particular two wheels or casters, so that the hand-held soil cultivation implement is transportable. The wheels or casters can be solid or hollow. It is also conceivable that the wheels are hollow and can be filled with air or another gas mixture or with a gas.

[0049] The support device can also include a locking mechanism, allowing it to be locked in the working position and / or the stationary position. It is also possible for the support device to be movable and lockable in other positions.

[0050] It is also conceivable that the support device incorporates a clamping mechanism. In the essentially relaxed position of the clamping mechanism, the support device is in the cleaning position. The support device can then be lowered into the upright position by a user. During the lowering process, the clamping mechanism is tensioned. In the upright position, the support device can then be locked in place with the clamping mechanism still engaged. The support device can be moved from the upright position to the working position by releasing the locking mechanism. Once the locking mechanism is released, the clamping mechanism relaxes, and the support device simultaneously moves from the upright position to the working position.

[0051] In this way, the support device can be lowered by the user's foot or hand in a back-friendly manner, and it can be moved back into the cleaning position by releasing the locking mechanism with the foot or hand, also in a back-friendly manner. This results in an extremely quick and gentle transition for the user from the working position to the standing position, or vice versa.

[0052] The support device can be lowered, with the first and third sections of the guide handle in a vertical position, until the rollers or wheels of the support device touch the ground. The soil cultivation implement is then supported on the ground by the wheels / rollers of the support device, the cleaning tools, and the squeegee. The vertical position of the support device, along with the first and third sections of the guide handle, results in a virtually vertical position for the soil cultivation implement. This allows for extremely space-saving storage of the soil cultivation implement, for example, in a utility room.

[0053] A support device with wheels / rollers allows the tillage implement to be pivoted around the wheel / roller axis by a user while in a substantially vertical, supported position, thus enabling it to be moved into a transport position. In the transport position, the implement is supported by the wheels / rollers and held by the user. From this position, the implement can be moved from one application location to another, or from one storage location to another. Thanks to the support device, the user does not have to bear the full weight of the implement; rather, a large portion of the weight is supported by the wheels / rollers. This makes the process extremely easy and efficient for the user.

[0054] Alternatively or additionally, the task is further accomplished by a hand-held soil cultivation implement comprising a soil section. The soil section includes at least one soil cultivation tool and a motor for driving the tool. The guide handle has a connection device for a supply hose. The connection device may include a coupling device in the form of a rotary union for a supply hose. The rotary union is designed such that a coupling element of a supply hose can be connected to the coupling device, allowing the supply hose to rotate freely relative to the guide handle. The rotary union may, in particular, be located in the first section of the guide handle.

[0055] This type of rotary joint allows the soil cultivation implement to be used regardless of the current position of the supply hose. In particular, the soil section of the implement can be used flexibly in narrow and / or angled areas without the supply hose significantly hindering its operation. Furthermore, the movable arrangement of the supply hose on the handle ensures that the user can position the soil cultivation implement in the cleaning direction necessary for optimal cleaning results. This movable arrangement also reduces the likelihood that a user might be tempted to use the implement suboptimally out of convenience, due to the potentially inconvenient positioning of the supply hose when fixed.

[0056] The coupling device, in particular the rotary feedthrough, can be designed such that wastewater and / or fresh water or cleaning fluid and / or electrical current and / or electrical signals can be conducted through the supply hose and the coupling device. The coupling device can comprise a wastewater coupling, a fresh water coupling or cleaning fluid coupling, and / or an electrical coupling and / or an electronic coupling. The electrical coupling can have sliding contacts. The wastewater coupling can comprise two interlocking pipes that are rotatable relative to each other. The fresh water coupling can comprise two interlocking pipes that are rotatable relative to each other and that enclose the wastewater coupling. The wastewater coupling and the fresh water coupling are thus arranged, in particular, coaxially.Freely rotatable means that the supply hose is arranged to rotate endlessly on the coupling device of the connection device. Fresh water and cleaning water or cleaning fluid are to be understood as equivalent in the context of the invention.

[0057] The coupling device of the hand-held soil cultivation implement can be connected to a coupling element of a supply hose. The supply hose can include a line for cleaning fluid and / or a line for wastewater and / or an electrical line and / or an electronic control line.

[0058] This type of coupling device allows multiple media and / or liquids to be routed to and from the bottom section of the tillage implement. A particular advantage is that the user can connect all lines running through the supply hose to the tillage implement in a single connection operation. This eliminates the need for the user to connect each line individually, minimizing both the number and duration of connections. The reduced number of connections required by the user also minimizes the risk of user errors. Therefore, the coupling device ensures that the tillage implement can be operated with exceptional efficiency and low susceptibility to malfunctions.

[0059] The control cable can transmit electrical or electronic signals to the tillage equipment. It is also possible for the electrical cable to transmit both electrical power and control signals.

[0060] The supply hose of the hand-held soil cultivation implement can be connected to a supply unit. The supply unit can include a carrying device for transporting it on the back of a user. The supply unit can also include a transport cart for moving the supply unit on wheels. The supply unit can include a power supply unit and / or a cleaning fluid tank and / or a dirty water tank and / or a pumping device and / or a suction device. The dirty water tank can include a defoaming device as described above.

[0061] A carrying device or transport trolley makes the floor cleaning machine particularly flexible and easy and comfortable for the user. The carrying device allows the machine to be used in areas that are inaccessible or very difficult to reach with ground-based equipment, such as stairs, corners, or slopes / inclined surfaces. A user carrying the power unit on their back with the carrying device does not need to carry a trolley during operation. Instead, the user can concentrate on the cleaning process, making it efficient and thorough. The power supply for the power unit can be wireless, for example, using a battery or accumulator. This eliminates the need for the user to lay a power cable that could potentially trip over passersby in public areas.This further enhances the flexibility in the application of the soil cultivation equipment described above.

[0062] The transport cart may include wheels and / or casters. The wheels and / or casters may be solid or hollow. The wheels may be inflatable with air or another gas mixture or gas. The transport cart may include a handle. The carrying device may be designed to be attached to the supply unit without tools. The transport cart may have a wastewater collection tray. The wastewater collection tray may be designed so that the base of the soil cultivation implement can be placed on it. This allows the soil cultivation implement to be transported on the cart after cleaning without wastewater dripping from the base onto the ground. The transport cart may also include a mounting device for the guide handle of the soil cultivation implement.Then the base can be placed on the wastewater collection tray and the guide rod can be placed in the guide rod holder.

[0063] The cleaning fluid tank and / or the dirty water tank of the hand-held soil cultivation equipment can be removed and attached without tools.

[0064] In this way, a user can conveniently remove or attach the cleaning fluid tank and / or the dirty water tank without tools.

[0065] The cleaning fluid tank and / or the wastewater tank can be attached to the supply unit using buckles or click devices, for example.

[0066] The base section of the hand-held soil cultivation implement can include two counter-rotating tools. These counter-rotating tools can be designed as cleaning discs. During normal operation, the axes of rotation of the tools may not be exactly perpendicular. Therefore, the axes of rotation of the tools are not parallel.

[0067] Such an arrangement and movement of the cleaning tools results in a forward motion of the hand-held soil cultivation device, enabling a user to use and operate the hand-held soil cultivation device particularly advantageously and with minimal effort.

[0068] The cleaning plates may include working elements such as brushes and / or mounting plates for scouring pads. It is also possible that the cleaning plates include other cleaning devices. The cleaning plates may be attached to the base of the soil cultivation implement in a way that allows them to be detached without tools.

[0069] The object of the invention is further achieved by a supply unit for a hand-held soil cultivation implement, in particular for a soil cultivation implement as described above. The supply unit comprises a power supply unit, a cleaning fluid tank, a dirty water tank, a suction device, and a connection coupling. In particular, the supply unit includes a pump device. The connection coupling can be connected to a supply line. The supply line can be connected either to a soil component or to a coupling device of a connection device.

[0070] A hand-held tillage implement can be operated advantageously with such a supply unit. The unit provides the tillage implement with all necessary media and energy in a compact and uncomplicated manner, while also removing wastewater.

[0071] The supply unit can be connected to a guide pole, a transport trolley, or a carrying device.

[0072] Such a supply unit can be flexibly adapted to the respective type of use, and therefore it is not necessary to buy three different devices.

[0073] The problem is further solved by a method for manufacturing a hand-held soil cultivation implement, in particular as described above. The method comprises the following steps: Manufacture of a supply unit as described above, in particular surrounding the supply unit with a housing, connecting the connection coupling to a supply line directly to the base part or a supply line to a coupling device or connection device.

[0074] A hand-held soil cultivation implement can be advantageously manufactured using this method. By connecting the coupling to a supply line, which is connected to the coupling device of a soil component or the coupling device of a connecting device, several versions of the hand-held soil cultivation implement can be produced using this method. It is possible to arrange the supply unit on the handle, thus creating a version of the soil cultivation implement in which the supply unit is attached to the handle and moved along with the handle by the user during cleaning. It is also possible to arrange the supply unit on a transport cart and then connect the coupling to the coupling device of a connecting device.Then, a user can perform the cleaning process using the base unit attached to the guide handle, while the power supply unit is mounted on the transport cart. Alternatively, the power supply unit can be mounted on a carrying device, and the connecting coupling can then be attached to the coupling device of a connecting device. In this case, a user can shoulder the carrying device with the power supply unit and perform the cleaning process using the base unit attached to the guide handle, while the power supply unit is on the user's back.

[0075] The object of the invention is further achieved by a method for cleaning a floor with a hand-held floor cleaning implement as described above. The floor section has an underside on which the at least one tool is arranged. The underside also has a squeegee, the squeegee being located behind the tools when viewed in the direction of movement of the floor section. During intended use, the squeegee is at least partially located on the side of the floor section facing away from the user. During intended use, the user walks backward and the floor section is guided in a meandering motion toward the user by means of the guide handle.

[0076] By positioning the squeegee blade on the side facing away from the user, the cleaning and wiping process can be carried out analogously to the previously known mopping or wet-wiping process. Furthermore, a single user can complete a cleaning cycle without having to re-enter the already cleaned area, as the user moves backward. This allows for a particularly effective cleaning result.

These show: Figure 1: A hand-held soil cultivation implement with a user; Figure 2: A hand-held soil cultivation implement with a supply unit on the handle; Figure 3: A rear view of a hand-held soil cultivation implement with a supply unit on the handle; Figure 4: A side view of a hand-held soil cultivation implement; Figure 5: A hand-held soil cultivation implement with a transport cart; Figure 6: A base section of a hand-held soil cultivation implement with a coupling device; Figure 7: A connecting coupling of a handle of a hand-held soil cultivation implement with a coupling device; Figure 8: A view of a base section of a hand-held soil cultivation implement; Figure 9: A rear view of a base section of a hand-held soil cultivation implement; Figure 10: A view of a connecting device, partially without a housing, with a wastewater line and a supply hose;Figure 11: A longitudinal section through a connection device; Figure 12: A view of a connection device; Figure 13: A view of a universal joint; Figure 14: A view of a support device; Figure 15: A view of a support device with a supply unit; Figure 16: A view of a supply unit with a wastewater tank; Figure 17: A view of a supply unit with a wastewater inlet; Figure 18: A view of a cover of a supply unit with a wastewater inlet and a wastewater defoaming device.
