- An engagement element is in particular disc-shaped with a recess 152.
- the recess 152 is azentrisch to the axis of rotation 148 and is in particular spaced from this.
- Counter elements 154 for the engagement elements 150 are arranged on the carrier device 62. These are positioned so that, with correct Vorposition réelle of the sweeping device 60 relative to the chassis 12 (with investment of the second bearing portion 124 to the fourth bearing portion 126 and positioning of the pins 132 in the recesses 128), the engagement member 150 can engage the counter element 154 in that the counter element 154 can dip into the recess 152.
- the respective counter-element 154 is in particular designed as a pin element which is arranged on the carrier device 62.
- the arm 138 engages with the rotatable member 146 in this area, the support means 62.
- An engagement element 150 can then act on the counter element 154 with respect to the direction of gravity g from above.
- the clamping device 154 is designed as an eccentric device. In a tensioning operation by rotation of the rotatable member 146 is also a translational movement of the support means 62 to the chassis 12, in order to achieve clamping of the first fixing device 112 with the second fixing device 114 on the contact areas 116, 120, 124, 126 in addition to the tension on the tensioning device 154.
- a recess 152 (cf. FIG. 7) is designed so that an eccentric function is achieved during a clamping with a translational movement in a first direction for clamping, and with a tension solution an eccentric function with an ejector function with opposite translational movement in a second direction (which of FIGS first direction is opposite) is reached.
- the recess 152 has a first flank 153a and an opposite second flank 153b. Between the first flank 153a and the second flank 153b there is a free space of the recess 152.
- the second flank 153b for example, is convexly curved.
- the first flank 153a is, for example, concavely curved. A distance between the first flank 153a and the second flank 153b is greatest at the open end side of the recess 152 and narrows in a funnel shape inwardly towards a transverse arrangement between the first flank 153a and the second flank 153b.
- the first flank 153a is formed so that upon rotation for tension (toward the bottom 22 and counterclockwise in the illustration of FIG. 7), it acts on a corresponding counter element 154 and a displacement of the carrier 62 towards the rear end of the chassis 12 causes.
- the second flank 153b is designed such that when the tensioning 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. It As a result, an ejector function with the solution of jamming at the contact areas 116, 120, 124, 126 is realized.
- a corresponding clamping position is releasable by rotation of the rotatable member 146; the rotation takes place in the arrangement of Figure 7 from the ground 22 away and clockwise.
- an actuator 156 such as a rod, is disposed on the rotatable member 146. Via the actuating element 156, a rotation for a bracing or for releasing a tension can be carried out from the outside.
- an engine such as an electric motor, to be provided as actuating element 156.
- the actuating element 156 is correspondingly articulated to the rotatable member 146, to allow for easy accessibility, a corresponding rotation for producing a clamping position or for solving a clamping position.
- the procedure is as follows:
- the carrier device 62 of the sweeping device 60 is positioned on the chassis 12.
- the first longitudinal member 98a and the second longitudinal member 98b are placed on the fourth abutment region 126.
- the corresponding unit is then displaced 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 at the front ends 130 of the side members 98a, 98b. It is then also a pre-positioning with respect to the contact areas 116, 120, 124, 126 reached.
- the fourth abutment portion 126 provides a support surface for downward support in this process.
- the tensioning device 144 is correspondingly positioned in relation to the pins 132, which is then possible by rotation of the rotatable member 146 about the axis of rotation 148 engagement of the engaging elements 150 to the associated counter-elements 154. As a result, a voltage is reached.
- a shift can also take place in which, in particular, the first abutment region 116 is pressed against the third abutment region 120.
- clamping device 144 which is actuated from the outside via the actuating element 156, this clamping position is secured.
- This clamping position can in turn be solved by turning on 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 displaced slightly forward.
- the fixing device 110 basically comprises three components, firstly the abutment component with the abutment regions 116, 124, 130, 126.
- the abutment takes place spatially in the region of the cross member 64 of the sweeping tool device 60.
- the fourth abutment region 126 can facilitate the production of a fixing position (clamping position), since a downward support is made possible.
- the fixing device 110 comprises the tensioning device 144 as the second component. A tension can be achieved via this.
- a counter element 154 of the first fixing device 112 is gripped to effect a tension.
- the fixing device 110 comprises, as a third component, the "swords" 98a, 98b with their recesses 128, in which the pins 132 of the second fixing device 114 can be positioned. It can thereby achieve a torque support for the sweeping device 60 on the chassis 12.
- the sweeping tool device 60 can be solved or mounted in a simple and fast manner.
- An interface is provided on the chassis 12 and also on the corresponding sweeping tool device 60, which allows a To fix variety of different tool devices on the floor cleaning machine 10.
- a sweeping tool 60 ' is provided, which is fundamentally the same as the sweeping tool 60, with the difference that a rotatable member 158 with engagement elements 160 is arranged on the sweeping tool 60'.
- Corresponding counter-elements 162 are arranged on a chassis 12 '.
- the operation is basically the same as described above.
- the corresponding tensioning device 164 differs from the tensioning device 144 in that the rotatable member 158 is now arranged on the sweeping tool device 60 'and the counter-elements 162 are seated on the driving part 12'.
- FIGS. 4 to 6 show the floor cleaning machine according to FIG. 1 with a different tillage implement 166, namely with a front-end lifting device 168.
- a front lifting device 168 serves, for example, for receiving a snow blade.
- the front power lift 168 is also shown in Figs. 13-17.
- the front power lifting device 168 can be detachably mounted on the chassis 12 via a fixing device corresponding to the fixing device 110.
- This fixing device has a second fixing device, which is arranged on the chassis 12. This is the second fixing device 114 as described above. This is used to fix the further tillage implement device 166 (such as the front power lift 168) to the chassis 12.
- the cultivating tool device 166 further has a first fixing device 112 ', which is fundamentally the same as the first fixing device 112 with regard to its component interacting with the second fixing device.
- the front power lift 168 includes spaced side rails 170a, 170b. These longitudinal members 170a, 170b form strips or "swords" with a recess 128 'at its front end 130'. In this, the respective pin 132 of the chassis 12 can be brought.
