Definitions
- the present invention relates to a machine for processing floors with a chassis, a soil processing device, in particular a grinding, polishing or scouring device, and with a suction device, the soil processing device comprising at least two rotating processing bodies, in particular grinding, polishing - Or scouring body, of which at least one can be changed in position to vary the working width of the tillage device, and wherein the suction device comprises at least one suction head arranged near the floor in the working direction behind the tillage device.
- a generic tillage machine with a variable working width is known from US-A 3,277,511. It is designed as a scrubber-drier and has a front-mounted scrub head, which is elongated due to the arrangement of several plate brushes next to each other. This elongated scrub head is offset around a vertical axis pivoted on the chassis so that one of the disc brushes can be moved on a circular path. Depending on the position of the scrub head set (transversely or more or less obliquely to the working direction), the working width determined by the projection of the scrub head in the working direction can be adjusted.
- the working width of the suction device which comprises a suction strip arranged in the rear area of the machine and connected to the suction head, can be adapted to the working width of the scrubbing device by providing a lateral extension, which is vertical Axially pivoted on the suction bar is pivoted more or less far out.
- the present invention is based on the object of improving the manageability and increasing the ease of use of generic tillage machines with a variable working width, as well as of a preferred embodiment to improve the work result.
- this object is achieved in that a positionally variable suction element or a positionally variable scraper strip, which supplies particles and / or liquid located on the floor to the suction head or a suction bar connected to it, is coupled to the or each positionally variable processing body is, so that the working width of the suction device automatically adapts to the working width of the tillage device. Due to the - expediently mechanical - coupling to the assigned position-changing processing body, the corresponding suction element or the corresponding scraper strip is always moved with it when the working width of the tillage device is changed.
- each positionally variable processing body in the working direction serves to guide the water or particle layer left by it on the floor inwards and to lead it to the area covered by a central suction strip.
- the separate suction element provided as an alternative to this is removed behind each positionally variable processing body likewise the layer of water or particles left by this on the floor.
- it is preferably coupled to the central suction device, ie connected to a central suction fan and a central separating device.
- the principle on which the invention is based can be used with all tillage machines which have a tillage device comprising a variable working width and comprising a rotating working body, in particular with machines with grinding, polishing or scouring devices.
- the corresponding machining bodies, in particular grinding, polishing or scouring bodies can likewise have any shape known in the prior art; in particular, they can be designed as plate brushes, roller brushes, grinding wheels or pads.
- the advantages presented below with reference to a rotating brush scrubber drier apply in a corresponding manner to the other claimed floor cleaning machines. Merely for reasons of clarity, where this appears expedient, reference is made to the specific design as a scrubber-drier.
- the positionally variable suction element coupled with each position-changing scrub brush or the corresponding squeegee is arranged immediately behind the assigned brush, ie at the smallest possible distance from it. This minimizes the area of the floor in which there is no suction of the liquid film when cornering and / or when the scrubber drier is used due to the reciprocating movement. If necessary, the corresponding positionally variable suction elements or scraper strips are arranged under the chassis of the scrubber drier in order to minimize the area in which suction is not carried out.
- the brushes of the scrubber drier can be arranged in a variety of ways. For example, one or more main brushes arranged in a stationary manner on the front and, in the working direction, one or two additional brushes which can be changed in position can be provided behind them. In another expedient embodiment of the scrubber-drier according to the invention, only positionally variable brushes, possibly combined into units, are provided, which are arranged one behind the other in the working direction are.
- the last-mentioned design has the advantage that the corresponding floor cleaning machine can be constructed very compactly and can clean corners well even with the largest working width.
- roller brushes and plate brushes can be used in the same way.
- Roller brushes are generally arranged to rotate transversely to the working direction;
- Plate brushes are expediently combined in groups or units of at least two, which are arranged next to one another transversely to the working direction and rotate in opposite directions, the plate brushes forming a group being moved uniformly to change the working width.
- main brush is understood synonymously with “stationary brush” and the term “additional brush” is synonymous with “position-changing brush”.
- the scrubber-drier has a central main brush unit and two additional brush units arranged behind it, of which one has a variable position on the one hand, and the other on the other hand • the position of the main brush unit can be changed.
- the respective position of each of the two additional brush units depends on the position of the other.
- Additional brush unit can preferably be selected independently.
- the suspension of the two additional brushes in the scrubber drier can be symmetrical about their longitudinal axis, ie the two are in the retracted position . Additional brushes next to each other. In this case, the working width of the individual additional brushes is limited to almost half the working width of the main brush, ie the total working width of the machine can be varied in a ratio of about 1 to 2.
- the two additional brushes can also be staggered one behind the other in the longitudinal direction of the machine.
- the working width of the additional brushes can be almost the same as the working width of the main brush, ie the total working width can be varied in the ratio of almost 1 to 3.
- a staggered arrangement of the additional brushes is provided in particular when using roller brushes.
- the respective inner ends of the scraper strips or suction elements are expediently guided in longitudinal guides, while the respective outer ends are assigned covers or frames with the additional brushes are firmly connected.
- the suction elements or scraper bars coupled with the position-changing brushes represent a telescopic extension of the central suction bar. This means that the inner ends of the scraper bars or suction elements are in or leads to the squeegee. This results in a very compact structure of the elements used to extract the water film with a high degree of efficiency.
- deflection rails are expediently provided, which prevent table legs or the like from getting between the housing of the scrubber drier and an extended auxiliary brush.
- deflection rails are also at one end at a fixed point and at their other end held in a longitudinal guide; the front end of each deflection rail is preferably articulated at a fixed point on the chassis of the scrubber drier, while the respective rear end slides in a longitudinal guide which is provided on the cover or frame of each additional brush.
- the additional brushes can be suspended on swivel arms, the other ends of which are articulated on the chassis of the scrubber drier; the various possible positions of the additional brushes lie on a circular path.
- the additional brushes can be moved linearly in a guide arranged transversely to the working direction of the scrubber drier.
- Such a suspension of the additional brushes is particularly expedient in the case of scrubber-drier machines which have only brushes or brush groups which can change position.
- the brushes or brush groups are preferably each stored in a frame designed as a slide, which is guided on two guide rails, for example, by means of guide rollers. which are arranged on the underside of the chassis.
- the additional brush (s) can be driven by means of a mechanical or hydraulic coupling with the drive of the main brush.
- the mechanical coupling of the main brush and additional brushes preferably has a speed ratio, ie the additional brushes rotate at a higher speed than the main brush.
- the abrasive effect reduced by the lower contact pressure of the additional brushes on the floor compared to the main brush can be compensated for by a higher frequency of the abrasive bristles, so that the main brush and the additional brushes have the same cleaning performance.
- each additional brush can also have its own drive motor. With this form of drive, each additional brush can be put out of operation as soon as it is in its fully retracted position (minimum working width), so that unnecessary wear of the bristles is avoided.
- the scrubber drier according to the invention can have spring elements which bring the additional brushes into their respective extended positions. If an additional brush extended in this way under spring force encounters an obstacle with its leading deflecting rail, the additional brush in question is removed from the obstacle against the spring force pushed in, exactly as far as is necessary to pass the obstacle. In this way, the entire working width adapts automatically to the respective local space conditions.
- a hydraulic change of the position of the additional brushes by means of known hydraulic cylinders and an electrical change of position by means of adjusting motors can be considered.
- a device which prevent double cultivation of the soil in the areas in which the working areas of two processing bodies overlap one another by one of the respective processing bodies in this area being out of contact with the ground brought.
- Such a device preferably comprises at least one cover plate, which is assigned to a brush near the floor, on which the bristles of the corresponding brush run in the area in which the bristles of the other brush rest on the floor.
- the "area” is understood to mean the strip directed in the working direction, which is processed by the corresponding brush when the machine moves forward in the working direction.
- the cover plate thus prevents multiple processing of the floor by preventing the bristles of one brush from coming into contact with the floor in the area in which the bristles of the other brush clean the floor.
- the floor is thus cleaned uniformly over the entire working range of the floor cleaning machine, irrespective of the working width set in each case, so that streaking as a result of multiple processing is reliably avoided.
- a single cover plate is expediently provided, the width of which corresponds to the working width of the main brush unit.
- a cover plate that is effective in the area of the second brush unit;
- the cover plate is arranged in the area of the rear brush unit and is coupled coupled to the front brush unit when the working width changes.
- the cover plate has a width corresponding to the working width of the front brush group and thus prevents the rear brush group from becoming effective in the area in which the front brush group has already cleaned the floor.
- both brush units can be moved in both directions from their central position; with a correspondingly large working width, the front brush unit on the left and the rear brush unit on the right, or else the front brush unit on the right and the rear brush unit on the left can protrude from the chassis. This is advantageous for cleaning corners.
- a cover plate is arranged stationary in the area of each of the brush units.
- Both cover plates are expediently each substantially half as wide as the working width of the corresponding assigned brush unit; they are arranged offset from one another so that the covered areas do not overlap, but rather adjoin one another in the middle of the machine.
- the cover plate assigned to the front brush unit covers the left half of the brush group that is retracted
- the cover plate assigned to the rear brush unit covers the right half of the rear brush unit that is retracted.
- the front brush unit always processes the area of the working strip that is on the right from the machine center
- the rear brush unit cleans the area of the working strip that is on the left of the machine center, regardless of the working width currently set.
- a further embodiment of the device which prevents double processing of the soil in tillage machines with plate brushes, can consist in the tufts of bristles being combined in sleeves which are slidably mounted in the plates in the axial direction, each Tufts of bristles are pressed onto the ground by a spring element acting on the sleeve; An electromagnet arranged above the plate brushes attracts the sleeves accommodated in a plate brush against the force of the spring element in the areas in which another brush cleans the floor, so that the bristle tufts accommodated in the respective sleeves except in the corresponding area Be brought into contact with the ground.
- a probe bracket connected to a pushbutton switch is expediently provided.
- the pushbutton switch When the corresponding brush or brush group is moved onto an obstacle, the pushbutton switch is actuated by the pressed-in pushbutton and controls the change in position of the corresponding brush / brush group in the sense of a reduction in the working width.
- a valve is expediently connected to the pushbutton switch which controls the application of the hydraulic cylinder serving to change the position of the brush / brush group in such a way that the corresponding brush / brush group is retracted.
