Definitions
- the invention relates to a tillage machine according to the preamble of claim 1.
- a generic tillage machine is for example known from DE 43 37 633 C2. She includes a non-circular tillage device Total working surface. As with such tillage machines is common to the tillage device a suction bar arranged afterwards, which is suspended on a holding arm, which by one vertical axis is pivotally mounted. The vertical Axle for the trailing and swivel-mounted The suction bar is located in the middle between the axes of rotation two main brushes.
- a scrubber drier is also from DE 91 15 713 U became known. It comprises two non-rotatable ones Wheels and a rotatable wheel offset from it as well as two offset to each other across the direction of travel horizontal plate brushes that work together with a suction brush. The plate brushes can be changed in position held.
- the present invention provides comparatively simple ones Funding improvements not previously thought possible.
- the tillage machine comprises a Soil cultivation device with non-circular cultivation area, for example in the form of two side by side arranged plate brushes. This tillage device is now pivotable about a vertical axis arranged.
- the processing device with the non-circular machining surface made of two next to each other in the direction of travel lying and oppositely drivable plate brushes exist for the present invention, that even when cornering the tillage machine this tillage body, for example in the form of Disc brushes each with their much larger overall transverse extent stay aligned to the direction of travel. This allows cornering when cornering and back out the floor with the processing body processed as broadly as possible and still fully processed or be cleaned.
- the swiveling processing device also an associated suction bar with swiveled, which optimally, for example, on the Soil applied water liquor can be sucked up.
- the squeegee can be used with the entire tillage device together in a fixed spatial assignment be pivoted or at least again in one small angular range suspended swinging relative to it his.
- a sibling solution has turned out to be special proven favorable when the tillage device with the at least one processing body also a Includes impeller, which with the tillage body is pivoted with. This impeller builds on that weight on him (from the chassis of the tillage machine) Lateral forces that define the rotation Let it run off and without the impeller sliding sideways or could slip away. If this is at least an impeller between the tillers of the tillage device and the squeegee that is relatively trailing is arranged, there is a particularly optimized Running behavior, because in the narrowest of spaces by sideways Swiveling the tillage machine the trailing squeegee can swing out to the side.
- the pivoting movement of the tillage device for example in the form of two adjacent plate brushes is preferably carried out via a trailing squeegee (especially if there is no additional pivoting one Impeller is provided), or via a pivotable Impeller, which together with the tillage device arranged pivotably and to the common vertical axis of rotation is aligned.
- a trailing squeegee especially if there is no additional pivoting one Impeller is provided
- a pivotable Impeller which together with the tillage device arranged pivotably and to the common vertical axis of rotation is aligned.
- a tillage machine is shown in the figures, usually a machine or housing body 1, a trailing control unit 3 and in Machine and housing body 1 comprises at least one motor, what about processing body 5a and 5b of a soil cultivation device 5 can be driven.
- a machine or housing body 1 usually a trailing control unit 3 and in Machine and housing body 1 comprises at least one motor, what about processing body 5a and 5b of a soil cultivation device 5 can be driven.
- the drive direction is usually such that in the forward direction 9 leading the plate brushes towards each other rotate.
- the two plate brushes shown in the exemplary embodiment 5a, 5b of the tillage device 5 can in one So-called.
- Brush box 12 can be housed, the two Disc brushes 5a, 5b essentially except for the area their drive axles 11 covered and above the ground 14 ends.
- the tillage machine comprises in the embodiment shown two rear non-steerable wheels 13 and a third, which can be swiveled forward Wheel 15, what the tillage implement held and is movable.
- the rear wheels 13 are on the underside of the tillage machine or the associated chassis supported and held.
- Soil cultivation device 5 is now vertical Axis of rotation 19 pivotable, the axis of rotation 19 at least indirectly on the machine or housing body 1 or pivotable on the associated chassis of the tillage machine is stored.
- the two are circular Tillage body 5a, 5b based on the Center longitudinal axis 21 of the tillage machine straight forward driving at the same height exactly next to each other.
- the two processing bodies 5a, 5b in the longitudinal direction of the Soil cultivation machine or at least in the direction of travel are slightly offset so that those of the Machining bodies 5a, 5b each covered area overlaps.
- A is firmly connected to the vertical axis of rotation 19 trailing arm 23 provided on the latter End in the central position attached to a suction bar 25 and is tracked.
- the suction bar 25 is on the fastening point 27 is firmly connected to the holding arm 23, so that the two tillage bodies 5a, 5b, the Holding arm 23 and the suction bar 25 a non-rotatable and jointly pivotable about the vertical axis of rotation 19 Form tillage device 5.
- the Holding arm 23 also supports the leading third wheel 15, between the two machining bodies 5a, 5b and the trailing squeegee 25.
- the leading Wheel 15 is opposite in the embodiment shown the holding arm 23 cannot be pivoted, but together with this rotatable about the vertical axis of rotation 19.
- the vertical axis of rotation 19 lies in the central longitudinal plane or intersects the vertical central longitudinal axis 21 of the tillage machine, preferably at the intersection between the the two drive axles 11 of the two machining bodies 5a, 5b connecting line and the central longitudinal axis 21.
- the tillage body is preferred in or on the area 5a, 5b via a not shown Line liquid, especially cleaning liquid, fed to the plate brushes, for example immediately in front of the plate brushes in the forward direction or on trickling the plate brushes or through the central axis through into the central area of the plate brushes, whereby a trailing liquid film to be taken up again from the floor, hereinafter also called water fleet 29 which is due to the trailing squeegee Aspirated floor and over a not shown Suction hose to a in the tillage machine, i.e. in the machine and housing body 1 Suction device is transported.
- a not shown Line liquid especially cleaning liquid
- the plate brushes for example immediately in front of the plate brushes in the forward direction or on trickling the plate brushes or through the central axis through into the central area of the plate brushes, whereby a trailing liquid film to be taken up again from the floor, hereinafter also called water fleet 29 which is due to the trailing squeegee Aspirated floor and over a not shown Su
- the suction bar 25 has thereby a width that is preferably at least slightly is wider than the maximum width of the entire machining body 5a and 5b. In the embodiment shown the suction bar 25 is slightly wider than the overall width the tillage machine.
- the rear Control unit 3 (which, for example, is transverse to the processing device extending handle bar includes) corresponding pressure to the left or right so exerted be that the front wheel 15 (which is opposite the vertical axis of rotation 19 but is arranged trailing) pivoted about this vertical axis of rotation 19 accordingly becomes.
- the entire tillage system is equally used 5 with the two tillage bodies 5a, 5b, the rotating front wheel 15 and the trailing squeegee 25 together around the common vertical axis of rotation 19 pivoted so that even Cornering the ground with the maximum width the processing body 5a and 5b processed and cleaned can be.
- the main weight is in the embodiment shown for example a weight of 500 N compared to a support weight of 300 N in the area of the brushes also that the respective roll-off point 33 at the leading Wheel 15 the point of application for pivoting the tillage device 5 is.
- the soil cultivation device can be used to clean corners staying in almost the same place their leading area are pivoted to the left so with a left swiveling the leading one vertical axis of rotation 19 with the entire tillage machine is taken to the left.
- the front wheel 33 will remain in alignment almost at the same place pivoted to the axis of rotation 19 to the left, whereby the entire tillage device 5 and the vertical Axis of rotation 19 the desired pivoting movement to the left performs.
- the arrangement can be such that the tillage device 5 around the vertical axis of rotation 19 um Can be rotated back and forth 360 °.
- the structure explained does not only make it an optimal one Tillage with the maximum width of the adjacent plate brushes 5a, 5b achieved, but also also ensured that the squeegee each in the immediately trailing area next to the two lying processing bodies 5a, 5b tracked to optimally absorb the water fleet.
- the steerable mentioned front impeller 15 not necessarily between the plate brushes and the squeegee, but also in trailing Direction can be arranged behind the squeegee. Indeed This results in a slightly different kinematics. With the wheel 15 trailing, the pivoting movement takes place slower or less dynamic. Because with an between the leading brush devices 5a, 5b and trailing suction bar 25 arranged impeller 15 this has the consequence that in one by the roll-off point 33 in Impeller 13 placed coordinate system when pivoting the vertical axis of rotation 19 on one side and the attachment point 27 for the suction bar 25 opposite lie on the other side of the impeller 33 and be pivoted about the support point 33.
- One increasingly extreme swiveling out of the suction bar 25 at already low front offset of the tillage machine is achieved when the impeller 33 and its Roll-off point increasingly closer to the vertical axis of rotation 19 come to rest.
- a pivoting of the brush box 12 with the brush device 5a, 5b is basically together with the Suction bar 25, but also without using the pivoting movement promotional impeller 13 possible.
- Words can be a or if there is enough space several wheels 13 also directly on the chassis of the tillage machine steerably attached when a collision avoided with the suction bar and the plate brushes can be.
- driver's seat machine As is basically the case reproduced in the representations according to Figures 5 to 7 is. It is possible that the steering wheel Driver seat machine connects to the vertical Axis of rotation 19, so that the operator on the Steering wheel controls the driver seat machine accordingly steered and thus forcibly the tillage device 5 pivoted with the trailing squeegee 25 and is adjusted.
- FIG 5 is the extension of a schematic Steering wheel rod 41 shown, for example, over two Toothed belt pulleys 43 and 45 and one rotating over it Toothed belt 47 with the tillage device 5 in Steering connection is in place.
- the swiveling wheel 15 adjusted to the left and right according to the direction of travel.
- the vertical adjustment axis 19 is laid here that it cuts the pivotable wheel 15 vertically and passes through the rolling point 33 of the pivotable wheel 15.
- the steerable wheel over an unspecified Drive mechanism for driving the device can be driven unless the rear wheels are driven.
- the tillage bodies are 5a, 5b together with the pivotable Wheel 15 and the suction bar 25 as a common brush and Suction unit pivoted, whereby, as stated, this unit also with a drive unit for the swiveling Wheel 15 can be connected.
- This also defines the width of the suction bar 25 in order to optimally absorb the liquid film over the entire suction width even during a pivoting process.
- FIG. 9 there is a larger swivel radius R max .
- R max the width of the suction bar 25 must be chosen larger.
- the first-mentioned exemplary embodiment according to FIG. 8 thus has more favorable conditions, since the smaller, i.e. narrower, suction strip used results in a minimum passage width in the case of obstacles, and, moreover, the suction power itself is greater since, with the same suction energy of a suction motor, only a smaller one Surface must be vacuumed.
- machining bodies 5a, 5b can be, for example, a plate brush and a cooperating revolving sweep belt or, for example a transverse sweeping belt or for example two slightly V-shaped sweeping straps, one or more rollers, one or more polishing plates etc., with polishing plates mostly cleaned dry is, so does not have to be suctioned off. Possibly could instead of a squeegee one without a suction device provided cleaning strip can also be arranged.
- a roller brush 5c can also be used, which are aligned transversely to the vehicle's longitudinal axis when driving straight ahead and about a horizontal axis of rotation 11 ' rotates.
- the wheel can of course run in front or behind to be built in.
- the suction bar 25 on the holding arm 23, for example at the attachment point 27 shown there, must not be firmly anchored and held, but that the attachment point 27 also formed as a pendulum axis can be about this at least in a small angular range an additional pendulum movement of the squeegee relative to enable the holding arm 23.
- the attachment point, which is also designed as a pendulum axis can be, but can also be much further ahead be provided on the holding arm 23, possibly even lying very close to the vertical axis of rotation 19.
