Definitions
- the present invention relates to a tillage machine with a chassis, a tillage unit and an operating and / or control unit for the tillage unit provided on the back of the machine, the tillage unit built on the chassis having a container unit with at least one a container for holding liquid and / or solid substances as well as other units, such as batteries, motors, pumps, blowers, separators.
- Soil cultivation machines of this type are known for a wide variety of uses, for example as floor cleaning machines in which the container is used to hold fresh and / or used cleaning liquid, as suction machines in particular for outside surfaces in which the container is designed as a dirt collecting container, and in particular as grinding machines for parquet floors in which the container is used to collect the grinding dust, or the like.
- floor cleaning machines in which the container is used to hold fresh and / or used cleaning liquid
- suction machines in particular for outside surfaces in which the container is designed as a dirt collecting container
- grinding machines for parquet floors in which the container is used to collect the grinding dust, or the like.
- the teaching under protection relates to all generic tillage machines to which it can be applied with the same advantages as in the case of the floor cleaning machines described below.
- generic floor cleaning machines can be designed in particular as scrubbing machines, sweeping machines, carpet cleaning machines or the like. They are known, for example, from US Pat. No. 3,277,511 or German Utility Model 91 15 713.
- a disadvantage of the known floor cleaning machines is that they cannot be used to clean the floor under tables or the like. Rather, tables must be cleared aside before the carpet or floor can be cleaned beneath them. This is due to the fact that the height of the known floor cleaning machine hardly allows tables to be passed under. The overall height of the known floor cleaning machines is determined by the size of the container unit for the cleaning liquid, which cannot be reduced in size without adversely affecting the possible service life of the floor cleaning machine.
- the present invention has for its object to provide a generic tillage machine with which an unobstructed processing of the floor is possible by objects located above the floor, such as tables, storage racks and the like.
- objects located above the floor such as tables, storage racks and the like.
- floor cleaning machines it should in particular be possible to clean the floor even under tables.
- the floor cleaning machine should not lag behind the known floor cleaning machines with regard to its performance data (cleaning performance, duration of use), but should rather be improved.
- this object is achieved in that at least one container of the container unit is suspended so that it can be changed in position and / or can be changed in shape, so that the height of its upper edge above the floor can be varied.
- no fixed unit or other component is provided in the working direction in front of the container unit, the upper edge of which is at the same level or even higher than the maximum height of the upper edge of the container, which is variable in length and / or shape.
- the overall height of the machine can thus be adapted to the respective conditions of use.
- the container unit is not surrounded by a fixed housing, a fixed cover, cladding or the like; either no cover is provided here at all, or it can be easily removed or lowered during operation of the machine with a reduced overall height.
- the container can also be clad with a fixed cover.
- the container unit consists of a plurality of containers exists, at least one of which is mounted in a positionally changeable manner.
- the at least one container which can be changed in position can then, depending on requirements, be brought into a higher or lower position.
- the container unit comprises two containers which are mounted so as to be pivotable about a horizontal axis. If the floor or carpet is to be cleaned under a table, the two pivotable containers can be pivoted outwards downward about their corresponding pivot axes.
- the container unit expediently comprises, in addition to its two positionally variable containers, a further, fixed container; this is preferably arranged directly under the pivotable containers (in their pivoted-up position).
- the container unit comprises two containers, each of which can be assigned an inclined guide. These inclined guides, if necessary, allow the two assigned containers to be shifted downwards and outwards, which likewise reduces the overall height of the container unit above the floor.
- the container unit can comprise a further, fixed container, which is expediently arranged directly under the displaceable containers. Compared to the embodiment with the pivotable containers, this embodiment has the advantage that the overall height can be adjusted continuously and adapted to the boundary conditions.
- the at least one container has at least two housing parts which can be pushed into one another and a variable-volume balloon or bellows arranged therein for holding the cleaning liquid.
- the volume changes when the vertical extent, ie the height of the container, varies.
- the floor With a correspondingly reduced volume of the container and thus a lowered upper part of the container, the floor can also be cleaned under tables or the like.
- a further advantageous effect of such a floor cleaning machine can be seen in the fact that by specifying a certain maximum volume of the container, the pressure exerted by the floor cleaning machine on the floor can be specified. This is of particular importance with regard to the cleaning of floors where the maximum permissible load must not be exceeded; this is the case, for example, with sports hall floors.
- the height of the respective upper edge of the fixedly arranged units assigned to the processing unit is substantially less than the maximum height of the at least one container. In this way it is ensured that the further aggregates assigned to the tillage unit do not impede the undermining of tables and the like at a relatively great depth when the container or containers are lowered. In this respect, this development is preferred over such an embodiment of the machine in which the fixed units are built up behind the container unit up to the maximum height of the container unit. Because in the latter embodiment, the floor cleaning machine could only be pushed under tables or the like, even with the containers lowered, until the fixed units abut the table edge or the like.
- the operating and control unit is connected to the chassis so that it can be changed in position.
- the operating and control unit can be pivoted to the chassis about a horizontal axis.
- By moving the operating and control unit downward, in particular pivoting, in such a floor cleaning machine it also prevents the cleaning of floors under tables or the like.
- the floor cleaning machine can only be pushed up to the stop of the operating and control unit at the edge of the table under the table even with a reduced overall height of the container, with the operator swiveled down, - and control unit completely push the corresponding floor cleaning machine under the table.
- the floor cleaning machine designed in this way is much easier to transport from one place of use to the other than with known floor cleaning machines. Because while the latter need a van or small truck for their transport, the floor cleaning machine according to the invention can, if the overall height is reduced, be accommodated in a station wagon. The storage of the floor cleaning machine according to the invention is also considerably easier because of the smaller space requirement when the liquid container is lowered than is the case with known floor cleaning machines.
- FIG. 1 shows the side view of a first embodiment designed as a scrubber-drier embodiment of the soil processing machine according to the invention
- FIG. 2 shows the view of the scrubber drier according to FIG. 1 from the front
- FIG. 3 shows the side view of a further preferred embodiment of the soil working machine according to the invention, which is designed as a scrubber-drier,
- FIG. 4 shows a view of the scrubber drier according to FIG. 3 from the front
- Fig. 5 is a side view of a third as
- FIGS. 1 to 5 The basic structure of the respective scrubber-dryer shown in FIGS. 1 to 5 is known.
- Units assigned to the cleaning unit are built on a chassis 1, which is supported on wheels 2 on the floor 3.
- These are in particular the drive motor 4 of the main scrubbing brush 5 arranged on the front, the accumulator unit 6, the pump unit 7 for the cleaning liquid and the suction and separating unit 8.
- the latter stands above the suction hose 9 with the rear suction strip 10 in connection.
- an operating and control unit 11 is provided, which comprises two handles 12 and an instrument panel 13.
- the container unit for the cleaning liquid comprises three sub-containers, namely a fixed container 14 and two position-variable containers 15, 16.
- Each of the two variable-position containers of the container unit is attached via hinges 17 with a horizontal pivot axis the upper edge 18 of the side wall 19 of the housing is articulated.
- the two position-changing containers 15 and 16 can thus be pivoted sideways outwards and downwards (in the position shown in dashed lines) to reduce the overall height of the container unit according to arrows A (FIG. 2) until their side wall 20 touches them of the side wall 19 of the housing.
- the two position-changing containers 15 and 16 are connected to the fixed container 14 via hose connections (not shown).
- the working width of the scrubber drier according to FIGS. 1 and 2 is thereby determined by the pivoting down of the positionally variable containers 15 and 16 increased the overall width of the structure of the scrubber-drier, so that the two additional brush devices 21 are pivoted out, as indicated in FIG. 2 for the left-hand additional brush device in the working direction with dashed lines.
- the operating and control unit 11 is arranged at the upper end of a housing section 22 which is connected to the chassis via a hinge 23 with a horizontal pivot axis extending transversely to the direction of travel.
- the housing section 22 together with the operating and control unit 11 can be pivoted backwards and downwards in accordance with the arrow B (FIG. 1), so that containers 15 and 16 and pivoted down housing section 22, the total height of the scrubber drier is not greater than the upper edge 18 of the fixed housing.
- the handles 12 each have a section with an almost horizontal course in their upper region, which enables the operator to guide the scrubber-drier safely and comfortably even when the housing section 22 is pivoted down.
- the controller 24 of the cleaning unit is arranged at the bottom In the area of the housing section 22, the controller 24 of the cleaning unit is arranged.
- the scrubber drier according to FIGS. 3 and 4 differs from that according to FIGS. 1 and 2 in that the two position-changing containers 15 and 16 are mounted on linear guides 25 which run obliquely outwards and downwards.
- the two containers 15 and 16 can be moved obliquely downwards-outwards by moving in the direction of the arrows C (FIG. 4), as a result of which the overall height of the container unit is reduced (cf. the maximum lowered position shown in FIG. 4 with dashed lines) of the two containers 15 and 16).
- Electrical spindle drives (not shown) are provided for displacing the heavy containers 15 and 16 along the linear guides 25 in the filled state.
- the scrubber drier shown in FIGS. 3 and 4 unlike that according to FIGS. 1 and 2, does not have any additional brush devices which can change position. With a corresponding design of the lowerable containers 15 and 16 in such a way that there is enough space underneath them for the additional brush device even in the lowered state, however, such can be readily provided.
- the housing section 22 carrying the operating and control unit 11 is connected to the chassis 1 via the joint 23, so that it follows the arrow B (FIG. 3) can be pivoted below-behind. 3 and 4, the same units are built on the chassis as in the case of the scrubber-drier according to FIGS. 1 and 2, namely the drive motor 4 for the main brush 5, the accumulator unit 6 and the pump unit 7 for the cleaning liquid and the suction and separation unit 8.
- the container for the cleaning liquid comprises a housing 26 and a variable-volume balloon 31 arranged therein for receiving the cleaning liquid.
- the maximum overall height of the container can be varied by constructing the housing of the container from two components 26a and 26b which can be pushed into one another.
- the lower housing section 26a comprises a cylindrical wall 27 and a bottom 28;
- the upper housing section 26b includes a likewise cylindrical wall 29 and a cover plate 30.
- the upper housing section can be move the housing section vertically. If part of the cleaning liquid is used up, or if the container is only partially filled for work under tables or the like from the beginning, the cleaning liquid only requires a corresponding proportion of the maximum volume of the container.
- the upper section 26b of the housing can thus be moved in accordance with the arrow D in the lower housing section 26a to adjust the container volume.
- 5 corresponds to that of the floor cleaning machine according to FIGS. 1 and 2, so that reference can be made to the corresponding explanations above.
