The multi-purpose working machine is designed for work requiring increased maneuverability in terrain, especially on slopes. Its frame has vertical bearings for vertical wheel pins, which are alternatively attached to movable horizontal arms. These are mounted in the frame's supporting guides and are equipped with arm brackets to which linear motors are hinged, hinged to the frame.

Description

(54) Multipurpose working machine, in particular for slopes

The multipurpose working machine is designed for work requiring increased maneuverability in the field, especially on slopes. On its frame there are arranged vertical beds for vertical wheel studs, which are alternatively attached to movable horizontal arms. These are mounted in the frame support rails and are provided with arm brackets to which linear motors articulated with the frame are articulated.

The invention relates to a multipurpose working machine, in particular for slopes.

In the case of energetic traction means or tool carriers, self-propelled working machines and machines coupled with a traction means, good maneuverability is a considerable problem, usually the more the rig or machine is larger or longer. On the slopes there is a further deterioration in working ability, because when working along the contour line, as most agricultural work is done to prevent erosion, the machine or the set runs down the slope sideways. A slope device, usually by tilting a machine on a chassis towards a slope, is provided with only a small portion of the mechanization means, in particular because of the constructional cost and cost of such devices. Although means or machines are known to rotate wheels about a vertical axis in order to increase maneuverability, for example when parking, such means are not capable of working on agricultural terrain and in particular not on slopes.

A multipurpose working machine, especially for slopes, removes these disadvantages. It is based on the fact that on its frame there are arranged vertical bearings for vertical wheel studs, which are alternatively attached to movable horizontal arms, which are mounted in the frame bearing guides and are equipped with arm brackets, to which linear motors articulated with framed.

The multipurpose machine, especially for slopes, according to the invention shows, with low construction complexity and low purchase and operating costs, very good maneuverability on the flat and on the slope, ability to work on sloping grounds and practically movability in any desired direction.

1 is a schematic side view of one embodiment of the machine, FIG. 2 is a plan view of FIG. 1, FIG. 3 is a side view of another embodiment of the machine, and FIG. 4 is a plan view of FIG. 2.

On a frame 1, for example a quadrangular plan, are preferably mounted in the corners a vertical bed 2 for receiving the vertical pins 3 with supporting forks 8 of the wheels 4, provided with a drive (not shown), for example a hydraulic motor. The vertical bed 2 does not have to be provided directly in the corners of the frame 1, but it is advantageous for stability and good maneuverability to be at least near the corners of the frame 1. Alternatively the vertical bed 2 can be arranged on movable horizontal arms 8 the guides 7 of the frame 1, but this is not a requirement. Advantageously, the movable arms 8 can be mounted in the support guides 7 rotatably and in order to be rotated about the horizontal axis, but also to fix their position, provided with arm brackets 9 to which linear motors 10, for example hydraulic cylinders articulated on The articulation of the linear motors 10 is preferably carried out by ball joints 12. A working machine (not shown), an energy source or other means of transport or working means is placed on the frame 1.

The multipurpose working machine according to the invention works as follows: By turning the wheels 4 by means of vertical pins 3 in the vertical beds 2 of the frame 1, it is possible to drive in any desired direction and thereby eliminate descent when working on slopes. For this purpose, it is particularly suitable for the embodiment with movable horizontal arms 6, in which a better adhesion of the machine to the slope can be achieved simply by turning around the horizontal axis. Increasing the spacing of the wheels 4 by extending them on the movable horizontal arms 6 is then useful as an increase in the track width, thereby increasing the stability of the machine when working on slopes.
