Definitions

• the invention relates to a tool holder arranged, on one hand, to be coupled to a working vehicle and, on the other hand, to be coupled to a tool.
• the invention relates to such a tool holder comprising vehicle-coupling members for alternative coupling to different working vehicles as well as tool-coupling members for alternative coupling to different types of tools.
• the invention aims at meeting the demand for greater flexibility to utilize different tools in a plurality of mounting positions and in connection with different types of working vehicles.
• This object is attained by a tool holder arranged, on one hand, to be coupled to a working vehicle and, on the other hand, to be coupled to a tool, comprising at least a first and a second tool-coupling member arranged for alternative coupling of different tools to the tool holder.
• the tool holder is characterized by comprising vehicle-coupling member arranged for the coupling of the tool holder in alternative positions of a working vehicle or to different working vehicles, as well as by a driving member carried on the tool holder and having an output drive shaft to drive a coupled tool.
• a tool holder in which a first vehicle-coupling member may be arranged for the coupling to a front loader mounted at the front part of a working vehicle, and in which a second vehicle-coupling member is arranged for the coupling to an arm for excavation mounted at the rear part of the working vehicle.
• the first tool holder is preferably formed as a front-loader holder, and the second tool holder as a three-point attachment.
• the driving member may be an electrically, hydraulically or pneumatically supplied motor, and may advantage ously be an electrically supplied servomotor.
• the tool holder may have a tool -coupling member comprising a pin having a first axial portion of a first diameter formed in order to form a component included in a front -loader holder, and having a second axial portion of a second and smaller diameter formed in order to mount an arm included in a three-point attachment.
• a tool holder comprises advantageously a tool-coupling member that has three fastening ears arranged with mutually aligned holes, the holes of a first and a second fastening ear of which have a common diameter corre - sponding to the diameter of the first axial portion of said pin, and the hole of the third fastening ear has a smaller diameter corresponding to the diameter of the second axial portion of the pin.
• Fig. 1 shows a working vehicle having tool holders according to the invention coupled in a front lifting arm as well as in an excavating arm carried at the rear part of the vehicle;
• Fig. 2 shows the tool holder in a perspective view
• Fig. 3 shows an alternatively arranged tool holder in a perspective view corresponding to Fig. 2.
• the tool holder comprises a supporting frame having a vehicle side and a tool side.
• a working vehicle such as a tractor equipped with a front loader, three-point attachment or excavating arm, or alternatively an excavator.
• a coupling member is likewise arranged for the detachable mounting of a tool on the tool holder.
• This coupling member is suitably a three-point attachment, a front-loader holder, or other holder for the detachable coupling of a tool.
• both the vehicle side and the tool side comprise at least two coupling members for alternative utilization of different tools and of different working vehicles.
• the tool holder has a box-like support frame 1 having a pair of opposite vertical side pieces 2 and 3, respectively, which in the lower ends thereof are connected by a horizontal bottom piece 4 and in the upper ends thereof by a horizontal top piece 5.
• the side pieces, bottom and top pieces of the support frame are shown as plates of steel, which are welded together in the corners of the support frame.
• the support frame is formed to carry the coupling member described below and may be given another constructive design than the one shown, such as a framework construction or girder construction, without the general idea of the invention therefore being abandoned.
• a first vehicle-coupling member is arranged in the form of a pair of hooks 6 (only one of which is visible in the drawing figure) and pin lead-throughs 7 for the coupling of the tool holder to co-operating members on the lifting arm of a front loader.
• the holder 8 may be arranged directly on the top piece 5 or indirectly by an intermediately coupled swivel joint 9, by means of which the support frame 1 can be tilted in an optional direction around the trunnion 10 of the joint.
• the tilting position is advantageously dynamically adjustable by means of at least one hydraulic cylinder 11, which engages between the support frame, or the top piece 5 thereof, and a holder 12 belonging to the tiltable part carrying the gate holder 8.
• one or two stays 11' of adjustable length may be arranged between the support frame and the holder 12 for a static adjustment of a tilting position.
• a first tool-coupling member is arranged in the form of a front-loader holder and comprising a pair of pins 13 as well as a pair of ears 14, 14' having through pins 15.
• a second tool-coupling member in the form of a three-point attachment comprising arms 16, which in the inner ends thereof formed with ears are articulately carried on the pins 15, and which in a conventional way are anchored in the support frame, for instance in the side pieces of the support frame by means of stays, such as the illustrated extensible stays 17.
• a pair of ears 18, arranged at the front edge of the top piece 5 of the tool holder for the lead-through of a pin belongs to the three- point attachment.
• a driving member 19 is arranged to drive a tool that is coupled to one of the tool-coupling members.
• the driving member 19 is a hydraulic motor driven by the hydraulic system of the working vehicle, which motor has an output drive shaft 20 to drive, for instance, snowblowers, grass mowers or other working tools, carried in any of the tool- coupling members.
• the driving member may, alternatively, have another supply, such as pneumatic or electrical, and may, for instance, be an electrically supplied servomotor.
• a pin 15 included in the tool holder is shown.
• the pin 15 has a head, from which a first axial portion 15' extends that has a first diameter formed in order to form a compo nent included in a front-loader holder.
• a second axial portion 15" further extends that has a second and smaller diameter formed for the mounting of an arm 16 included in a three-point attachment.
• the support frame 1 has three fastening ears 14, 14' and 14" having mutually aligned holes.
• the holes in a first and second fastening ear 14, 14' has a common diameter corresponding to the diameter of the first axial portion 15' of the pin 15, and the third fastening ear ' 14" has a smaller diameter corresponding to the diameter of the second axial portion 15" of the pin 15.
• the tool holder according to the invention provides an increased utilization of working vehicles and tools, and allows unlimited freedom of choice to couple any tool either to the front or the rear of the working vehicle, notwithstanding whether the vehicle is equipped with a loader or an excavating arm.
• the tool holder according to the invention allows simultaneous utilization of different or co-operating tools coupled both to the front and to the rear of the vehicle, such as is illustrated in Fig. 1. In this way, not only the flexibility of the fleet of vehicles is increased, but also the working capacity by the fact that, for instance, double grass mowers or snowblowers can be operated simultaneously using one and the same vehicle, the working width of which in this way can be doubled during one and the same working operation.
