  • the EP 2 778 288 A2 discloses a floor cleaning machine with a chassis, wherein a base and an attachment are provided and the base and the attachment are releasably connected to one another in a locking position.
  • the invention is based on the object of providing a floor cleaning machine of the type mentioned at the outset, on which a tool change (a change of the floor working tool device) can be carried out in a simple manner.
  • the fourth contact area is designed as a support area for the at least one soil working tool device and forms a lower support surface in relation to the direction of gravity, and that the third contact area and the fourth contact area are on a cross member and/or are arranged on one or more longitudinal members of the chassis.

  • the assembly and removal of a corresponding soil working tool device can be carried out in a simple and quick manner.
  • the first abutment area and the second abutment area are opposite and facing away from each other. As a result, they can be formed on an element such as, for example, on a longitudinal member of a soil-working tool device. It can be achieved in a simple manner, a tension.
  • the third abutment area and the fourth abutment area are opposed and face each other. In this way, a deadlock can be achieved with an element that is positioned between the third contact area and the fourth contact area.
  • the fourth contact area can also be used as a contact surface and supporting surface downwards if it is below the third contact area in relation to the direction of gravity. This facilitates the assembly process and simple pre-positioning is achieved.
  • the third contact area can then also be used to prevent tipping during an assembly process.
  • the fourth contact area is designed as a support area for the at least one soil working tool device. In relation to the direction of gravity, it forms a lower support surface. This lower support surface facilitates an assembly process.
  • the second fixing device has an immersion space between the third contact area and the fourth contact area has, in which an element of the first fixing device with the first contact area and the second contact area can be immersed. This makes it easy to achieve clamping between the corresponding element (such as a side member) of the soil working tool device on the chassis. It is a simple assembly possible and also a quick disassembly possible.
  • the first contact area and/or the second contact area has at least two spaced-apart partial surfaces and/or the third contact area and/or the fourth contact area has at least two spaced-apart partial surfaces.
  • This provides a large contact surface. Spaced abutment surfaces can be provided to allow for effective assembly and disassembly. A risk of tipping during an assembly process and disassembly process is reduced.
  • the third contact area and/or the first contact area has an inclined contact surface in relation to a longitudinal direction of the chassis, with a distance between the third contact area and the fourth contact area in particular varying in the longitudinal direction of the chassis and in particular Decreased direction from a front end to a rear end of the chassis.
  • a tolerance compensation is thereby provided.
  • Pre-positioning can be carried out, which does not have to be "exact" for final assembly.
  • the clamping device can then be used to finally apply the contact areas to one another for clamping.
  • the third contact area and the fourth contact area are arranged on a cross member or on one or more longitudinal members of the chassis.
  • the tensioning device is designed in such a way that an element of the first fixing device (such as a longitudinal beam) is connected to the first contact area and the second contact area to an element the second fixing device (such as a cross member) can be clamped to the third contact area and the fourth contact area.
  • an element of the first fixing device such as a longitudinal beam
  • the second fixing device such as a cross member
  • the clamping device comprises an eccentric, through which a relative translatory movement between the at least one soil working tool device and the chassis can be brought about during a clamping process and/or during a release process of a clamping.
  • This allows pre-positioning to be achieved in a simple manner during an assembly process. A final positioning is then achieved during bracing. This makes assembly easier. It can be done faster. Furthermore, certain tolerances are then also permitted for the elements of the fixing device.
  • An eccentric function when releasing a tension makes disassembly easier. If a tension is released, then the relative translational movement can move the soil working tool device out of a clamped position ("ejector function"), for example, and to a certain extent pre-position it for disassembly.
  • the tensioning device comprises a rotatable member on which one or more engagement elements are arranged, and the tensioning device comprises one or more counter-elements for the engagement element or elements, wherein (i) the rotatable member is arranged on the first fixing device and the or the Counter elements are arranged on the second fixing means, or (ii) the rotatable member is arranged on the second fixing means and the counter element or elements are arranged on the first fixing means. Access can thus be achieved in a simple manner, in which case tension (in addition to the jamming at the contact areas) is realized between the soil working tool device and the chassis.
  • the at least one engagement element has a recess into which the counter-element can be brought, with the recess in particular being acentric to an axis of rotation of the rotatable member.
  • An eccentric arrangement can be used to implement an eccentric, in which case a relative translational movement between the at least one soil cultivation tool device and the chassis is then made possible, in order to achieve final positioning with bracing, in particular from a "rough" pre-position of the soil cultivation tool device to the chassis.
  • the at least one engagement element has a recess with a first flank and a second flank, wherein the action of the first flank on a counter-element can cause a displacement of the counter-element in a first direction, and when the second flank acts on a counter-element, a displacement of the counter-element can be effected Displacement of the counter-element can be effected in a second direction opposite to the first direction.
  • the first flank and the second flank lie opposite one another.
  • the second flank is, for example, convexly curved.
  • a displacement of the counter-element (and thus a carrier device on which the counter-element is arranged) can be obtained via the first flank between the carrier device and the chassis, which presses contact areas against one another when a clamping position is brought about on the clamping device.
  • the second flank can act on a counter-element and thus on the carrier device in order to move the carrier device in an opposite direction.
  • An ejector function is thus implemented, which is a type of pre-positioning for dismantling.
  • An actuating element can be assigned to the rotatable member.
  • the actuating element is, for example, a rod, with an operator's gripping area on the actuating element being spaced apart from the rotatable one limb is. This makes it easier to carry out a clamping operation and also makes it easier to release a clamping.
  • the fixing device has at least one bar with a recess open at the front and the second fixing device has at least one pin for receiving in the recess, the pin in particular being able to be brought into the recess by sliding the at least one bar.
  • the pin is designed as a mushroom, for example.
  • the at least one pin is at a distance from the third contact area and the fourth contact area and/or the at least one recess on the at least one strip is at a distance from the first contact area and the second contact area. This results in an additional torque support in order to achieve a firm fixation of the soil working tool device on the chassis.
  • the at least one pin is preferably arranged on a longitudinal member of the chassis. It can protrude to an opposite side of the chassis or protrude outwards.
  • the at least one slat (such as a side member of the tillage implement) may be positioned between side rails of the chassis, or at least one side sill of the chassis may be positioned between slats.

  • the recess 152 has a first flank 153a and an opposite second flank 153b. There is a free space of the recess 152 between the first flank 153a and the second flank 153b.
  • the second flank 153b is, for example, convexly curved.
  • the first flank 153a is, for example, formed in a concave manner.
  • a distance between the first flank 153a and the second flank 153b is largest at the open end of the recess 152 and decreases like a funnel inward toward a transverse arrangement between the first flank 153a and the second flank 153b.
  • the first flank 153a is designed in such a way that during a rotation for bracing (towards the bottom 22 and in the illustration according to figure 7 counterclockwise) it acts on a corresponding counter element 154 and causes a displacement of the carrier device 62 in the direction of the rear end of the chassis 12.
  • the second flank 153b is designed in such a way that when the clamping position is released, it acts on the corresponding counter-element 154 and displaces the carrier device 62 in the direction away from the rear end 26 of the chassis. As a result, an ejector function is implemented with the release of a jam on the contact areas 116, 120, 124, 126.
  • a corresponding clamping position can be released by rotating the rotatable member 146; the rotation occurs in the arrangement according to FIG figure 7 away from the floor 22 and clockwise.
  • an actuator 156 such as a rod is disposed on the rotatable member 146 .
  • a rotation for clamping or for releasing a clamping can be carried out from the outside via the actuating element 156 .
  • a motor such as an electric motor, to be provided as the actuating element 156 .
  • the actuating element 156 is correspondingly linked to the rotatable member 146 in order to enable a corresponding rotation to produce a clamped position or to release a clamped position with easy accessibility.
  • the procedure is as follows:
  • the carrier device 62 of the sweeping tool device 60 is positioned on the chassis 12 .
  • the first longitudinal member 98a and the second longitudinal member 98b are placed on the fourth contact area 126 .
  • the corresponding unit is then shifted in the longitudinal direction 28 of the chassis 12 until the respective pins 132 of the second fixing device 114 are immersed in the associated recesses 128 on the front ends 130 of the longitudinal beams 98a, 98b.
  • a pre-positioning with respect to the contact areas 116, 120, 124, 126 is then also achieved.
  • the fourth abutment area 126 provides a support surface for downward support during this process.
  • the clamping device 144 is correspondingly positioned in relation to the pins 132 , which then, by rotating the rotatable member 146 about the axis of rotation 148 , allows the engaging elements 150 to engage with the associated counter-elements 154 . This creates tension.
  • a clamping between the carrier device 62 and the chassis with respect to the second fixing device 114 at the contact areas 112, 116, 120, 126 is achieved.
  • This clamping position is secured by the clamping device 144, which can be actuated from the outside via the actuating element 156.
  • This clamping position can in turn be released by turning the clamping device 144 in the opposite direction.
  • the second flanks 153b act on the counter-elements 154 and an ejector function is implemented, in which the sweeping tool device 60 is pushed slightly forward.
  • the sweeping tool device 60 can then be pushed out accordingly.
  • the fixing device 110 basically comprises three components, firstly the contact component with the contact areas 116, 124, 130, 126.
  • the contact takes place spatially in the area of the cross member 64 of the sweeping tool device 60.
  • a deadlock can be carried out there.
  • the fourth contact area 126 in particular can make it easier to establish a fixing position (clamping position), since downward support is made possible.
  • the fixing device 110 includes the tensioning device 144 as a second component.
  • a mating element 154 of the first fixation device 112 is gripped by the rotatable member 146 of the second fixation device 114 in order to effect a bracing.
  • the fixing device 110 comprises the “swords” 98a, 98b with their recesses 128 as a third component, in which the pins 132 of the second fixing device 114 can be positioned. A torque support for the sweeping tool device 60 on the chassis 12 can thereby be achieved.
  • the sweeping tool device 60 can be detached or assembled in a simple and quick manner by the fixing device 110 .
  • An interface is provided on the chassis 12 and also on the corresponding sweeping tool device 60 which makes it possible to fix a large number of different tool devices on the floor cleaning machine 10 .
