Figures 2a - 3 show a rotator according to the prior art. Figures 4a - 8b show an adapter and an arrangement according to the invention, as well as forms of application thereof. The arrangement in Figure 1 consists of the work machine boom 12, on the boom attached work tool 14 and rotator 16, which is attached to the work tool 14 and suspended in the boom 12. In this device according to the prior art, the work tool 14 is a multifunction grip 15, which comprises body 32, loading means 34, cutting means 36 and the actuators 38 of the loading means 34 and the vertical and horizontal rotary 40 of the multifunction gripper 15, i.e. in this case the tilt cylinder 40. For the hydraulic system of the multifunction gripper 15, a hydraulic flow is directed to the multifunction gripper 15 by means of the hydraulic lines 44. The figure does not show the two hydraulic lines going to the rotator. Unlike the figure, the hydraulic lines 44 are attached to both the multifunction gripper 15 and to the boom 10 15 20 25 30 35 8 12, 15 limited rotatable in relation to the vertical relation of the rotator 16 to which means that the multifunction grip is only a shaft. When the multifunction grip 15 is rotated in the boom 12, the hydraulic lines 44 are braided around the rotator 16 and finally prevent the multifunction grip 15 from rotating.
    In an arrangement according to the invention, the work tool 14 can for instance be a completely corresponding multifunction grip as in the arrangement in figure 1. In an arrangement according to the invention all hydraulic lines 44 which are led from the work machine are connected to the rotator 16. The direct hydraulic lines 44 connections according to 15 are definitely needed. to the multifunction grip not in an arrangement according to the invention. More specifically, the hydraulic lines 44 are attached to the valve unit 28 included in the adapter, which is and the adapter in turn to the upper part 22 of the rotator 16, statically attached to the boom 12. The adapter 26 and the valve unit 28 are shown in Figures 4a - 6. The multifunction gripper 15 is in turn attached at the lower part 24 of the rotator 16, which. is mounted to the upper part of the rotator 22 and thus arranged to rotate about the vertical axis of the rotator 16. During rotation, the upper part 22 of the rotator 16 remains in place and only the lower part 24 is rotated. With such an arrangement, movement restrictions caused by the hydraulic hoses are avoided.
    In this context, the cutting member 36 may be a cutting steel, which in its shape is disc-shaped and whose cutting edge is sharp. The felling of the trees is near. the cutting steel takes place so that the loading means 34 of the multifunction gripper 15 pulls the cutting means 36 through the trees, i.e. the multifunction gripper 15 moves in the direction of the trees during the cutting. The actuators 38 of the loading means 34, i.e. in this case the gripping cylinder 38 closes and opens the loading means 34 of the multi-function gripper 15, i.e. in this case the jaws. The cutting member can also e.g. which is operated by hydraulic flow. be a saw, the operator of the load machine The operator of the work machine maneuvers and controls the multifunction gripper and its load means by means of control devices. The control devices can be known lever or button controls or corresponding control devices suitable for the purpose. The workpiece actuator can be controlled via cable or wirelessly, if power is provided to the actuator. 16 prior art for an arrangement according to the invention Figures 2a - 2d show a suitable rotator as seen from different directions without an adapter. The rotator shown in the figures can be according to the state of the art and it can be used in an arrangement according to the invention by connecting to the upper part 22 a boom stop 46 for the attachment of the rotator 16 to an adapter according to the invention. The rotator boom, hose protection 30 for protecting the hydraulic lines and input connections 48. The input connections 48 can according to 16 flow channels, ie. here there are 6 input connections. the example being two less than the rotor's input connections 48 can be for the left and right movement of the rotator, for closing and opening the gripping cylinder and for the functions of a third optional actuator.
    The number of input connections can vary according to the number that the work tool needs, but input connections are advantageously at least 6. In this context, the terms input and output connections are used to distinguish the connections, although both input and output connections can be used to carry a hydraulic flow to a work machine and to return it from the work machine.
    The lower part 24 of the rotator 16 in turn comprises the output connections 50, which are two fewer than the input connections 48. This is because two of the input connections 48 direct a hydraulic flow to the lamella rotor 52 of the rotator 16 (in Figure 3). The hydraulic flow is directed from the input terminal 48 to the output terminal 50 using the internal flow channels 20 of the rotator 16 (in Figure 3). Figure 3 shows an exploded view of a rotator according to the prior art of the arrangement. The various components of the figure are described by name in the sub-list. Inside the rotator 16 there is a lamella rotor 52, by means of which the lower part 24 of the rotator 16 is rotated relative to the upper part 22. The lamella rotor 52 consists of a stator part 56 included in the upper part 22 of the rotor part 54. The stator part 56 is included in the rotor part. The rotor part 56 moves and rotates the fastening part 105 of the lower part 24, in which the fed hydraulic flow rotates the rotor part. In this case, the stator part 56 is static and the one on the shaft 103 inside which 20.
    Inside the rotor part 54 are the shaft 103, 16 the flow channels 20 of the rotator 16, the hydraulic flow goes to the rotator 16 from which the flow is distributed to different runs of the rotator flow channels via lower part 24 ring grooves, output connections. In this application form, four flow channels are shown, but the number of flow channels may vary according to the application form.
    Figures 4a and 4b show an adapter 26 according to the invention attached to the rotator 16. The adapter 26 is arranged to be able to be attached to the original hose cover 30 of the rotator 16 shown in Figures 2a - 3, the adapter 26 replacing the hose cover 30. Preferably used for attaching the adapter 26 the mounting stops 33 and mounting screws 31 provided for the hose protection, both of which are shown in more detail in Figure 5. The adapter 26 comprises a 28, 70, 72 additional part 74. The valve unit 28 may consist of two valve packages 60 '60 ", both valve unit a body part mounting stop and one comprises 50 ', according to which 48' the figure, input connections and output connections The input connections 48 'are intended for attaching the hydraulic hoses coming from the working machine to the valve unit 28' and the output connections 50 'for directing the hydraulic flow from the valve unit 28 to the rotor 16 input connections 48. The application form in Figure 4a deviates from the application form in Figure 4b in this way that both valve packages 60 '60 "4b of the valve unit 28' 60" 4b the valve packages 60 'are located on opposite sides of are located near the 60 "rotator 16. Common to both applications, in Figures 4a and 4b, compactly arranged in connection with the upper part 22 of the rotator 16, there and each other, figure is that the valve unit 28 included in the adapter 26 is it is protected from shocks. Figure 5 shows an adapter 26 detached from the upper part of the rotator 22. It is easy to fasten the adapter 26, since for this purpose the original hose protection fastening screws 31 or bolts can be used. The adapter can be fastened in the original fastening stop 33 of the rotator, which are more than the fastening screws 31 needed for fastening the adapter. If necessary, there may be several different mounting stops 72 on the adapter for different bolt pitch of different manufacturers' rotators or the locations of the adapter mounting stops may vary. In connection with the adapter, completely common commercially available valve packages without special solutions can be used as the valve unit's valve package.
    Figure 6 shows an adapter 26 according to the invention attached to the upper part 22 of a rotator together with a collision guard 35.
    The collision protection can be a capsule-shaped construction that protects the 77 hydraulic hoses. The collision guard can be attached to the adapter 16 valve unit, with hose openings for using the collision guard's mounting stop 72 '.
    Figure 7 shows an example of the connection of the hydraulic flows 28 to the valve unit 28. The hydraulic flows 28 coming from the rotator control 'to the valve package 60' of the left valve unit are attached. Fastening takes place at the input connections 48 '.
    The valve package 60 'distributes the flow as required to the rotor input connections C1 and C4 or to the actuator input terminals C2 and C3. The valve package 60 'is controlled by means of the pilot control line input connection LV and return connection LD. The hydraulic flow of the gripping cylinder 60 'is supplied to the right Valve package 60 "on this side. The valve package 60" distributes the flow when using the gripping cylinder to the input connections A and B and to the pilot control lines LV and LD of the left valve package 60'.
    The function of the valve unit 28 is described in more detail in Figure 8a of the hydraulic diagram, in which the rotator 16 and the valve unit 28 are shown, which consists of the valve packages 60 'and 60 ". In the figure, the pressure valve directional valve 62 of the left valve package 60' is in direct flow position 64 under pressure from pilot control flow LD.
    In this case, the input flow P1 of the hydraulics can flow directly to the lamella rotor of the rotator 16 via the connection C4 of the rotator 16 and the rotator and return flow P2 directly via rotation, the connection C1 returns through the directional valve 62. 8b 62 in cross flow position 66 under pressure from the pilot control flow LV.
    P1 In the figure, the pressure-controlled directional valve is controlled by the inlet flow through the cross-flow position 66 of the directional valve via the connection C3 of the rotator 16 and the return flow returns via C2. The ones marked on the rotator 16 mean the connections C2 'and the connection in the lower part of the rotator. C3 'the output connections of existing actuators in the same way as A' and B '. The hydraulic input flows A and B coming to the loading means of the multifunction gripper are led directly via the right valve package 60 "to the rotor connections A and B and via these to the loading means.
    The valve package 60 "comprises the pilot package 60 'of the valve package 60', by means of which a part of the input flows A and B is diverted to control the directional valve 62. When the loading means actuator with the control device is controlled to a position when the multifunction grip loading means is closed or opened 66, can be moved whereby the tilt cylinder of the multifunction gripper can be controlled by the rotator 69. With the throttle 69 of the pilot control unit 68, the switching speed 10 for the position of the direction valve 62 can be regulated.The direction valve 62 is pressure controlled at least from one position, the other may be spring controlled .
    In an arrangement the multifunction gripper of the rotator according to the invention is rotated by hydraulic flow by means of the tilt cylinder nv to the cutting position and to the folding position. Furthermore, during the closing and opening movements of the multifunction gripper, the tilt cylinder of the multifunction gripper can be used to change the position of the multifunction gripper. The hydraulic flow coming to the actuator of the loading means sets the directional valve 62 to a position where a command coming from the control device of the rotator 16 enables a hydraulic flow to the actuator enabling the tilt cylinder, whereby the loading means and the tilt cylinder can be used simultaneously. In other words, with the aid of the inlet flow of the rotator hydraulics, the rotator and the tilt cylinder of the multi-function gripper can be used alternately. 60 'The changeover takes place by means of the valve package direction valve 62.
    With this arrangement, the multifunction gripper can be rotated with the rotator when the loading means of the multifunction gripper are immobile.
    In this case, the directional valve 62 is set in direct flow position 64, whereby the hydraulic flow coming from the control device of the rotator 16 comes to the lamella rotor of the rotator 16.
    An adapter and an arrangement according to the invention are suitable for use generally in connection with various work machines, for example forestry machines, general cargo cranes or for which a rotator together with hydraulics is used. In any application, with other work tools that need a work tool according to the arrangement, there may be one or more actuators that are operated with hydraulics, e.g. cylinders. Such work tools can be e.g. multifunction grabs, cranes, agricultural loaders, excavators, drills or sweepers.
    The arrangement can also be used for post grips provided with a saw. 14 The adapter is suitable for connection to devices according to the state of the art without changes to the hydraulics of the work machine. boom or According to an application, locking valves can be used for the connection of the hydraulic lines to the actuators. 5 Standard hydraulic hoses can be used for all hydraulic lines.
