    FIELD OF THE INVENTION The invention relates to a method for attaching a harvester unit to a crane tip.
    Background of the invention In a forestry machine, between the harvester unit and the crown tip, there is usually a tilt device of the harvester unit and a rotating device, ie. a rotator. The tilting device usually comprises a two-branch tilting bracket, between whose (usually non-pointing) brackets the harvester unit is mounted in a rotatable manner so that it can be rotated than a vertical cutting stroke to a horizontal branching or cutting stroke. The rotation usually takes place with hydraulic cylinders mounted between the tilt bracket and the harvester unit. The rotator typically comprises two relatively rotatable parts, of which the upper (fixed) part is mounted on the crown tip and the lower (rotatable) part on the tilt bracket, in a position transverse to the axis of rotation between the tilt bracket and the harness unit. Between these there is a rotating device (eg a hydraulic motor) which is arranged to rotate the rotatable lower part relative to the fixed upper part. Thus, the rotator thus makes it possible to rotate the tilt bracket and the harvester unit coupled thereto relative to an axis which is transverse to the axis of rotation of the tilt bracket (and which is vertical when the harvester unit is used for cutting and treating wire). Usually there is between the part of the rotator coupled to the crown tip and the crown tip another ball joint (or another joint which is rotatable relative to two axles), i.e. a handle, by means of which the rotator can be held in a vertical position independent of the layer of the outermost boom In the crane.
    Due to the currently known mounting kits between the harvester unit and the tilting device as well as the mode of operation of stable devices for rotation, the rotation speed of the harvester unit increases as the harvester unit approaches its surfaces. This causes a sudden stop of the rotational movement when the harvester unit reaches its breaths. A softer stop is sought with e.g. the rotating cylinders of the tilting device fitted with steamed ducts. However, 2 does not work well enough in all conditions. When the rotary cylinders move towards the rear duct stopper, they usually reach their dead center, whereby the steaming is inefficient. During feeding of a tree trunk, the tilting device can also take in the rear stop device, which is the answer to provide a functioning steaming buffer. In addition, when the gripper is brought to the trunk of the tree, it often takes in a stone or the like, whereby the impulse which is transmitted through the tilt bracket and the rotator to the crown tip is transmitted to the spirit of the cab. In some cases, there is a plate mounted on the bottom of the saw blade, provided with steaming, but it only helps with the latter problem. In addition, it is a heavy solution. Steaming elements are also used in feed rollers. However, they do not solve the whole problem field either. One solution has been that the Ora tilt bar is as flexible as possible, but the fatigue of metal has become a limiting factor.
    Common features of the above-mentioned disadvantages are the need to change screws in the fastening of the tilting device and the rotator at relatively short intervals so that the tilting device and the harvester unit do not fall from the loader in an uncontrolled manner. The rotator and the handle and their joints and bearings are also exposed to heavy loads. Other components and bearings of the gripper are also exposed to hard blows. The driver's own ability to work is improved, if blows and noise do not come as a body-sounding spirit to the driver's cab.
    Brief Summary of the Invention The object of the invention is to present a new attachment of the harvester unit to the crane tip, to prevent transmission of striking shakes and impulses than the harvester head and other oscillations transmitted along structures through the tilt device and rotator to the crane and thereby on to the base machine. other properties of the devices between the harvester unit and the crown tip.
    The object of the invention is achieved with the attachment of the harvester unit, in which a steaming means has been arranged either between the crown tip and the rotator, between the rotator and the tilt bracket, or between the tilt bracket and the harvester unit to vaporize impulses and oscillations in the harder unit. In a more precise manner, the fastening of the harvester unit according to the invention can be drawn from what is presented in the characterizing part of claim 1. The dependent claims 2-10 present some formable embodiments of the fastening of the harvester unit according to the invention.
    The advantage of the fastening according to the invention is that a substantial improvement is achieved in the resistance of the harvester unit, the rotator and the tap. The convenience of using the machine is also improved, since impact impulses caused by impact are no longer transmitted as strongly to the crane and thereby to the driver's cab.

    According to a second aspect of the fastening according to the invention, the steaming means is located between the crown tip and the rotator.
    According to a third aspect of the fastening according to the invention, the steaming means is located between the tilting device and the rotator.
    According to a fourth aspect of the fastening according to the invention, the tilting device comprises a fixed part which is fixed to one end of the rotator, and the steaming means is located between the fixed part of the tilting device and the other spirit of the rotator.
    According to a fifth aspect of the fastening according to the invention, the fastening comprises a first fastening piece and a second fastening piece, and the first fastening piece is fixed on the first side of said fixed part and the second fastening piece is fixed on the second side of said fixed part.
    According to a sixth aspect of the fastening according to the invention, the fastening comprises a first steaming means and a second steaming means.
    According to a seventh aspect of the fastening according to the invention, the first damping means is located between the first fastening piece and the first side of the fastening part 4, and the second forming means means between the second fastening piece and the second side of the fastening part.

    Description of some embodiments of the fastening according to the ugg invention in detail Figure 1 shows a harvester head 10 which comprises, from the crown tip raked, a handle 20, a rotator 30 and a tilt device 40 and a harvester unit 50.
    The tilt device 40 comprises screens and paint containers and i.a. rotary cylinders for rotating the tilt device 40. The harvester head 10 also comprises a saw device 60, debris 70 and feeder 80. The harvester head 10 is shown in Figure 1 in the layer in which it is driven against a wire to be cut. In this position, the tilt device 40 is in its highest position against a stopper.
    The harvester unit 50 is thus fixed to the crown tip by means of the preceding parts mentioned above (the crown tip is not shown in the figures). In that case, the above-mentioned unit, which consists of the harvester head 50, the tilting device 40, the rotator and the handle, is fastened to the crown tip from the handle 20 by means of a fitting 21 provided with a braking device on its carrying spirit.
    Thanks to the handle 20, the rotator 30 and the tilting device 40 are automatically held in a vertical position, regardless of the position of the last boom in the crane. The brake devices located in the hinge of the handle 20 vaporize the pivot of the rotor 30, the tilt device 40 and the harvester unit 50 so that the rotator 30, the tilt device 40 and the harvester unit 50 would not swing when they are moved with the crane Than one place to another. However, when there is a heavy thread in the gripper of the harvester head 10, some kind of oscillation occurs. In this case, the handle 20 functions as a means which allows the oscillation with steam as much as possible between the harvester head 10 and the crown tip.
    The rotator 30 consists of a fixed part 31 in its first spirit and a relatively rotating part 32 in its second spirit. Between these parts there is a rotating device 33 which is usually e.g. a hydraulic motor.
    The tilt device 40 comprises a tilt bracket 41 and a fixed part 42 and rotating cylinders (not shown in the figures) located in its upper part and fixing openings 411 and 412 for the harvester unit 50, in which existing fixed joints on the side of the harvester unit 50 are mounted when the harvester unit 50 is attached to the tilt device 40.
    Figure 2 shows the above-mentioned parts of the harvester head presented in Figure 1 between the crown tip and the harvester unit 50, seen obliquely from below. It should be noted that in Figures 2-7, for the sake of clarity, the rotating cylinders of the tilting device 40 which are associated with the pivoting of the harvester unit 50 have not been shown, nor the harvester unit 50 itself. Figure 2 shows only the tilt bracket 41 and the fixed points 413 and 414 of the rotary cylinders. The rotary cylinders are e.g. double-acting hydraulic cylinders. Figure 3 shows the above-mentioned parts, seen directly from the front. Figure 4 shows the rotator 30 and the tilt bracket 41 of the tilt device 40 cut at the line A-A presented in Figure 3, and Figures 5-7 show these parts so that the parts between the tilt device 40 and the rotating part 32 of the rotator 30 are detached from each other.
    In this embodiment the upper part of the tilting device 40 is provided with a circular fixed part 42, on both sides of which there are disc-shaped fastening pieces 425 and 426 in size and shape of the fixed part, and between these and the fixed part 42 steaming means 423 and 424 of a material which vaporizes oscillations.
    The steaming means 423 and 424 are in this embodiment circular, disc-shaped rubber pieces, the diameter of which is the size of the fixed pieces 425 and 426, as shown in Figures 2-7. In that case, they are fixed by hot or cold vulcanization between the fasteners 425 and 426 and the fixed part 42 of the tilting device 40 so that the lower steaming means 423 is fixed between the lower fixed piece 425 and the lower surface 421 of the fixed part 42, and the upper steaming means 424 is fixed between the upper surface 422 of the fixed part 42 and the upper fixed piece 426. Such a uniform construction makes it i.a. easier to release the tilt device 40 and to attach it to the rotator 30 again. The lower fastener 425 is provided with guide sleeves 427, which are fitted through sleeve neck 428 in the fixed part 42 of the tilting device 40, in the steaming means 423 and 424 and in the upper fixed piece 426, when the tilting device 40 is fastened with its fixed part 42 to the rotator 30. The fastening comprises, as shown in Figures 2-7, fasteners 425 and 426, steaming means 423 and 424 and fastening means 429 which hold the fixed part 42 towards each other and against the lower surface 32a of the rotating part 32 of the rotator 30 in place. In it, the embodiment is the fixed screws, which are adapted when mounted through the guide sleeves 427 in the lower fastener 425 and are screwed into threaded screw holes 322 in the rotating part 32 of the rotator 30. When the tilt device 40 is fixed, the guide sleeves 427 of the lower fastener 425 come against the lower surface 321 of the rotating part 32 of the rotator 30 and thus prevents screw screws 429, which are adapted through them, from pressing fasteners 425 and 426 too hard against the fixed part 42 of the tilting device 7, in order to keep the damping shape of the structure optimal. The length of the guide sleeves 427 is suitably suitable with the male view of this property. Another function of the guide sleeves 427 is to convey the rotary motion generated by the rotator 30 and the Than crane to the linear motions of the tilt device 40 so that the damping action of the coupling thus formed which dampens impulses, vibrations and noise is as good as possible. pa despite the power dissemination.
    The tilt device 40 also comprises stops 415 and 416, which stop the swinging movement of the shoe unit 50. Also, they may be made of rubber, elastomer or any other material which vaporizes blows on the tilt device 40 when the harvester unit 50 hits the stops 415 and 416.
    When using a harvester head according to Figure 1, beating impulses and vibrations are transmitted from the harvester unit 50 to the tilting device 40. From the fixed part 42 of the tilting device 40 they are transferred to steaming means 423 and 424 and - steamed through them - to the rotator 30. Thanks to the steaming means 423 and 424 reduce vibrations caused by rotation of the tilting device 40 and a hit by the harvester unit 50 on a rock, as well as the load caused by them, in other parts of the harvester unit's attachment to the crane. The transmission of noise along these parts to the machine's cab is also reduced.
    Figures 8-10 show a second embodiment of the fastening according to the invention. In these figures, the tilting device, the rotator and the handle are the same as in Figures 1-7. Figure 8 shows the parts coming between the crown tip and the harvester unit 50 obliquely seen from below, when the parts belonging to the coupling between the tilting device 40 and the rotator 30 are detached from each other. Figure 8 shows parts coming between the crown tip and the harvester unit 50, the section B-B shown in Figure 9 and the section A-A shown in Figure 10. Also in Figures 8 and 9, the parts of the coupling point between the rotator and the tilt bracket are shown detached from each other. The harvester unit 50 and the rotary cylinder are also not shown in Figures 8-10.
    The difference to the liner according to Figures 2-7 in the liner according to Figures 8-10 is that in the liner according to Figures 8-10 the fixed part 42 of the tilting device 8 is not vulcanized, but the corresponding steaming means 423 and 424 are vulcanized between a disc-shaped piece 425 or 426 of the type previously presented, and a thinner spacer 425 'or 426'. Figure 9 shows in dotted lines the parts to be vulcanized together in the embodiment. It has the embodiment provided that intermediate pieces 425 'and 426' which are to come against the fixed part 42 I6 of the tilting device 40 are seen with the fixed part 42 e.g. with joysticks or lirn (not shown in the figure); otherwise there is a risk that the fastening screws 429 are subjected to excessive lateral forces.
    The fasteners presented above represent two slightly different examples of the fastener according to the invention. The damping property of the fastening according to the invention can also be achieved with steaming means for steaming vibrations, which are to be mounted in the second stables between the crane tip and the harvester unit. Other embodiments in addition to the one presented above are to place a steaming means between the rotator and the crown tip (eg in the handle). The steaming means can also be located in the lower spirit of the tilting device, close to the pivot joint of the radar unit or even in the torsion joint. There, the disposition of space places certain limitations on the realization.
    However, the steaming means need not be disc-shaped, but can be formed into a suitable shape for its position. In a pivot joint the steaming means could be e.g. sleeve-shaped or annular and placed e.g. between sleeves mounted in the joint bearing. The material for the vaporizing means may, instead of rubber, be e.g. which is a highly suitable elastomeric material, such as e.g. natural rubber (NR), ethylene propenediene monomer rubber (EPDM) or urethane, which may be fiber-reinforced or unreinforced urethane. The steaming means can also be a bearing structure of several slender materials, or another suitable combination structure of different materials. The structure of other parts of the fastening according to the invention can also vary. For example, the type of rotator may vary. The invention can be applied, for example, in a rotator which is provided with a rotatable feed-through inlet, where pressure medium required by the stables present after the rotator is passed through the rotator so that e.g. the harvester unit does not need to be guided pressure medium hoses which extend past the rotor and limit the angle of rotation of the rotator. The invention is thus not limited to the embodiments described above, but it may vary within the scope of the appended claims. 9
