Definitions

  • the invention relates to a boom for a vehicle with a main arm pivotally attached to the vehicle frame and a rocker arm pivotally attached to the main arm, to which a work tool is attached.
  • the invention is therefore based on the object of providing a boom which can be used very well as a locomotion aid without the risk that the harvester head is damaged or that its possible uses are restricted.
  • a generic vehicle is known from US 4,444,542 A.
  • two arms are mounted parallel to one another on the frame of a turntable, each arm consisting of a main arm and a rocker arm pivotably mounted on it.
  • There is a working tool on the luffing arm of each boom e.g. an excavator shovel and a hydraulic hammer attached.
  • the technical effort can be considerably reduced, since only a single main arm has to be provided, so that only a single hydraulic cylinder is required to actuate the main arm, which has an advantageous effect on the costs of the boom.
  • the weight can also be considerably reduced in comparison to the vehicle of US 4,444,542 A, which is very important in particular in the case of woodworking machines which have to move in the forest and on steep and rough terrain.
  • the boom according to the invention also has the advantage that existing booms on vehicles can be easily replaced by a boom according to the invention without special changes in the mounting of the main arm on the vehicle frame being necessary, since only a single main arm is still provided, whereas the Vehicle according to US 4,444,542 A a second storage for the separate rocker arm is required. Finally, a visual obstruction by the second boom during work is avoided.
  • the two rocker arms attached to the main arm can either be pivoted together or independently of one another on the main arm.
  • a Harverster head is attached to a rocker arm.
  • On the other rocker arm there is a device that can be used as a locomotion aid. This can be, for example, a conventional excavator shovel or a pile-like tool with which the working machine can be supported at a suitable location in the field eg to overcome a steep incline or an obstacle.
  • the locomotion aid is located on a second rocker arm, the tool on the first rocker arm is not exposed to the risk of damage and its use is in no way restricted.
  • Front loaders for work vehicles are described in US 4,797,051 A and DE 27 14 613 A1.
  • parking supports are attached to the front loaders, which are folded up or pushed in during operation and are therefore inoperative.
  • Fig. 1 an embodiment of a boom according to the invention is shown schematically, wherein the mounting of the main arm 1 on the vehicle and the vehicle itself are not shown, since it can be conventional bearings or vehicles that are not for the present invention are of particular importance.
  • the boom 1 is preferably mounted on a so-called walking excavator known per se, the spider legs of which can be extended and which enable a very strong level compensation.
  • the boom according to the invention consists of a main arm 1, at the free end of which two rocker arms 2, 3 are pivotally mounted about a bearing axis 4.
  • Main arm 1 as is usual, can be pivoted in the direction of double arrow 5 with the aid of a hydraulic cylinder 6.
  • the rocker arms 2, 3 can be pivoted separately from one another by means of double-acting hydraulic cylinders 7, 8.
  • the rocker arms 2, 3 are also telescopically extendable, the rocker arm 2 consisting of three telescopic elements 2 ', 2 "and 2"', whereas the rocker arm 3 consists of only two telescopic elements 3 'and 3 ".
  • the telescopic apart and The rocker arms 2, 3 are pushed together in a manner known per se via hydraulic cylinders, not shown in the drawings.
  • rocker arms 2, 3 do not have to be mounted next to one another on aligned axes 4 on the main arm 1, as shown in the drawings, but the bearing points of the rocker arms 2, 3 can lie independently of one another at any desired locations on the main arm 1. Furthermore, the rocker arms 2, 3 themselves can consist of several partial rocker arms articulated to one another.
  • rocker arm 2 On the rocker arm 2 is a work tool, not shown, e.g. a harvester head arranged. Any travel aid, not shown, is attached to the rocker arm 3, the range of which is less than the range of the rocker arm 2. Since, according to the invention, the locomotion aid is attached to a separate rocker arm 3, it can also be used to support the vehicle during a machining operation in order to give the vehicle better stability, which is particularly advantageous when the rocker arm 2 is fully extended.
  • the two rocker arms 2, 3 can also be connected to one another and pivoted together with a single hydraulic cylinder, which may reduce the possible uses of the boom according to the invention, but is a more cost-effective variant.
  • This embodiment can be used, for example, so that the rocker arm 3 is retracted during a machining operation with the harvester head. For Locomotion with the help of the rocker arm 3, however, the rocker arm 2 is retracted with the Harversterkopf and the rocker arm 3 extended more or less as needed.
  • the boom according to the invention is preferably used in vehicles for woodworking in difficult or steep terrain. However, it can also be used for vehicles for other purposes, e.g. for construction vehicles, can be used advantageously if e.g. additional support of the boom is desirable in difficult or steep terrain.
  • an embodiment of the invention can be represented as follows, for example:
  • a boom for a woodworking vehicle has a pivotable main arm 1 and a rocker arm 2 pivotally attached to the main arm 1 on a vehicle frame.
  • rocker arm 2 On this rocker arm 2 is e.g. a harvester head attached.
  • Another rocker arm 3 is mounted on the main arm 1, on which a locomotion aid, e.g. an excavator shovel is attached.
  • the locomotion aid and the harvester head can be used independently of one another in this way without the function of the harvester head being impaired.
