Abstract

The invention relates to a multi-purpose working device, in particular, for producing flat surfaces. Said working device comprises a rear frame, a front frame, a central part which connects the rear frame to the front frame, and a tool-maintaining device which is connected to the central part by means of an adjusting system, such that said tool-maintaining device can pivot in an essentially perpendicular manner in relation to the longitudinal axis and essentially parallel to the base counter to the central part.The rear frame and the front frame comprise wheels. The central part comprises at least one stationary part and another part which can be displaced counter thereto, such that the displaceable part can be displaced, essentially, in the longitudinal direction in relation to the stationary part. The front frame comprises a front wheel which can rotate about an angle range of at least 120 degrees, preferably at least 180 degrees, a hydraulic control which acts upon the front wheel for directional control, and a hydraulic drive which is used to drive the front wheel.

Claims (10)

1. Multi-purpose working device (1), in particular, for producing flat surfaces, having a rear frame (11), a front frame (10), a central part (20) connecting the rear to the front frame, and a tool holder (90) connected to the central part (20) via adjustment means (70), such that the tool holder (90) substantially is pivo-table perpendicular to the longitudinal axis and substantially parallel to the ground against the central part (20), whereby the rear (11) and the front frame (10) have movement means (40, 41), preferably wheels, and whereby the cen-tral part (20) has at least a fixed (22) and a part (21) movable thereto, such that the movable part (21) is moveable substantially longitudinally against the fixed part (22), characterized in that the front frame (10) has - a front wheel (40), - means for direction control, preferably a hydraulic control acting on the front wheel, whereby the means for the direction control preferably are provided such that they can rotate the front wheel (40) over an angle range of at least 120 degrees in total, preferably at least 160 degrees, especially preferred of at least 180 degrees, and - a drive, preferably a hydraulic drive, for driving the front wheel (40).
2. Multi-purpose working device according to claim 1, characterized in that it has a pivot between the rear frame (11) and the central part (20) by means of which the central part (20) is pivotable, preferably by means of a hydraulic system, substantially parallel to the ground against the rear frame (11).
3. Multi-purpose working device according to one of the previous claims, char-acterized in that it has adjustment means (70) for adjusting the horizontal and the vertical angles of the tool (30) connected to the tool holder (90) relative to the ground.
4. Multi-purpose working device according to claim 3, characterized in that the adjustment means (70) are adjustable decoupled with respect to each other and separate from each other.
5. Multi-purpose working device according to claim 3, characterized in that the adjustment means (70) have hydraulic components.
6. Multi-purpose working device according to one of the previous claims, char-acterized in that the tool holder (90) has a displacement device substantially for lateral extension of the tool (30)
7. Multi-purpose working device according to the previous claim, characterized in that the movable (21) and the fixed part (22) of the central part (20) are substantially movable against each other telescopically, preferably by means of a hydraulic system.
8. Multi-purpose working device according to one of the previous claims, char-acterized in that the front frame (10) has means for receiving further members, preferably of additional weights or further apparatuses, especially preferred of further soil working apparatuses.
9. Multi-purpose working device according to one of the previous claims, char-acterized in that a three points hydraulic system is attached at the rear frame (11), which is intended for receiving further and other tools, preferably of soil working devices.
10. Multi-purpose working device according to the previous claims 3 to 6, charac-terized in that it has at least one distance measurement device by means of which substantially the vertical distance of the tool (30) connected to the tool holder (90) can be determined relative to the ground, as well as that it has a control means, which is intended for the control of the distance between the tool (30) and the ground, whereby the control means moves the tool (30) con-nected to the tool holder (90) by adjusting the vertical distance of at least one side of the tool (30) relative to the ground such that a previously set vertical distance between the tool (30) and the ground is kept substantially constant during changing ground by means of the control means.
