STRUCTURE OF THE ROTARY EQUIPMENT AND THE SIMILAR ROTARY EQUIPMENT AND FORESTRY MACHINE
The invention relates to a structure of a rotating device comprising
- a first inner body member comprising first passageways arranged in the first inner body member for passing pressure medium through the first inner body member,
- a second outer body member at least partially disposed about the first inner body member in a rotatable manner, comprising connections arranged on the second outer body member for passing pressure medium through the second outer body member,
- second passages arranged either on the outer surface of the first inner body or on the inner surface of the second outer body or both to guide the pressure medium in all relative positions of the first inner body and the second outer body to the first channels,
an axial passage for passing electrical conductors through a first inner body portion comprising two ends,
- bearing means adapted to allow rotation of the second outer frame member relative to the first inner frame member and vice versa, which bearing means are adapted to carry axial and radial loads.
The invention also relates to a corresponding rotating device and a forestry machine.
The invention relates to rotary devices and their structures, in particular to rotary devices used in forestry machines or machine tools. In particular, the invention relates to a rotating device for use in a forestry machine between a boom and a harvester head and to its construction.
Nowadays, the rotary equipment used in forestry machines mainly uses winged hydraulic motors. One such is disclosed in EP 2460758 B1. In known solutions, the hydraulic hoses passing to the harvester head are routed externally from the boom or from the end of the boom to the rotating device or harvester head. Exporting the hydraulic hoses to the rotating device or harvester head causes the rotation of the rotating device, and thus the harvester head, to be limited due to the limited length of the hydraulic hoses because the hydraulic hoses have to rotate with the rotation of the harvester head.
EP 2460758 B1 discloses a rotary device having a lead-through for conducting an electric cable. The problem with this design, however, is that the rotating device is not freely or unrestrictedly rotatable, since the hydraulic flow is not passed through the rotating device, but the hydraulic hoses are attached directly to the harvester head. A further problem with the publication is that the hydraulic hoses travel from outside the boom to the harvester head or actuator, which limits the rotation of the harvester head relative to the boom and exposes the hydraulic hoses and their joints to external shocks and stresses. In practice, the maximum rotation angle of the harvester head at the end of the rotation device is limited due to the limited length of the hydraulic hoses. In addition, the structure of the rotation device is tall, bulky and heavy. All of the above problems make the rotating device impractical to use and susceptible to damage.
Further, WO9937136 is known from the prior art, which discloses a continuously rotating rotary device in which both the hydraulic and electric wires can be passed through the rotary device. In this embodiment, however, the pivoting device of the rotating device is integrated into the side of the rotating device and rotates the body parts of the rotating device relative to one another as a side pull. Thus, the structure is very difficult to modify to be compatible with components of different manufacturers, whereby the user of the structure of the rotating device is tied to a single component supplier.
The object of the invention is to provide a structure which is better than the prior art rotary device, which allows both fluid pressure flow and electrical conductors to pass through the rotary device, free rotation of the rotary device and modularity of the structure to be compatible with CAN manufacturers and adapters. It is also an object of the invention to provide a rotary device which is superior to prior art rotary devices, which allows both fluid pressure flow and electrical conductor passage through a rotary device to rotate and rotate, the adapters. The object of the invention is also to provide a forest machine which is superior to prior art forest machines, which allows both the flow of the pressurized fluid flow and the passage of the belt through for various manufacturers of turning equipment, bearings and CAN adapters.
This object may be achieved by a structure of the rotating device including a first inner body member comprising first channels arranged in the first inner body member for passing pressure medium through the first inner body member, the second outer body member being at least partially circumferentially disposed about the first inner body member. connections on the outer surface to the inner surface of the body member through the second outer body member to either the first inner or second outer ridge lugs and the second positions of the first structure for axially engaging the first inner two ends and the bearing still or all of the first mutual
In addition, the second pressure medium j and the other channels are provided for junctioning the outer frame member with the channels belonging to the body member. a linear duct through an electrical conduit body member fitted to the first bearing means of bearing radial loads.
comprising allowing a connecting means adapted to the inner body for coaxially engaging the first inner body to be swiveled on the axial channel to be coaxially coupled to the first body to be swiveled with the first to be mounted to the coil and a second substantially frame axis of rotation between the outer outer body portion for passing electrical conductors through a pivoting device to be connected to the structure.
Preferably, the suspension means of the structure are attached to the first inner frame member for hanging the structure of the rotation device on the boom. In this case, the fitting of the standard motor under the coaxially arranged inner and outer frame members is simple, even though the rotary adapter is located on the underside of the motor. Unlike hydraulic connections, rotary power supply / communication requires radially little space and electrical wiring can be provided in a relatively narrow channel to the adapter.
By means of the structure according to the invention, both the pressure medium flow and the electric conductors can be passed through the rotating device so that the rotating device is freely rotatable. In other words, the pressure medium hoses from the boom to the pivoting device and the electric conductors are connected to the upper part of the pivoting means and the other, via a harvester head or other similar implement attached to the boom. The axial channel formed in the structure allows electrical conductors to pass through the rotating device to be attached to the structure, while the first channels, connections and second channels in turn pass through the fluid medium flow in all relative positions of the first inner body part and the second outer body part. By directing the electric wires directly to the structure through the pivoting device to be connected by means of connecting means, the pivoting devices of different manufacturers can be connected to the structure, since the axis of rotation of the pivoting devices is generally hollow. This leaves the sides of the structure free, allowing the use of various bearing means, such as a circumferential bearing, in connection with the structure.
Preferably, the first inner body portion and the second outer body portion are radial to each other. In this context, radiality means that the parts are nested radially.
It is to be understood in this connection that said axial channel is substantially axial, meaning that the channel may also be slightly inclined at an angle relative to the axis of rotation between the first inner body member and the second outer body member.
Preferably, there are at least three first passageways, interconnections and second passageways, whereby the pressure medium flow has at least a pressurized line, a return line and a leakage line which can be introduced separately from the boom and harvester head.
Preferably, the axial channel is coaxial with a substantially convergent axis of rotation between the first inner body portion and the second outer body portion.
The axial channel can then be completely straight and coaxial.
It is to be understood in this connection that the first channels and connections form a plurality of passageways of the structure of the rotary device which are open / accessible in all rotational positions of the structure of the rotary device. At the same time, it should be understood that electrical conductors are electrical conductors intended to transmit one or more voltages, currents, or electrical signals.

Preferably, at least one of the following functionalities: the electrical feedthrough, the bearing and the swivel device are modularly integrated into the structure. In this case, these parts of the rotary device are easily removable and / or replaceable, in other words they are not integrated in the structure.
Preferably, the first inner frame member or the second outer frame member is adapted to be hung on a boom, one of which is adapted to hang the harvester head on the rotating device. Instead of a harvester head, another rotary implement or tool, such as a grapple or other similar device, can be hung on the rotation device, which must be rotated and supplied with electrical control and pressure medium flow.
Preferably, the axial duct is formed by a separate sleeve shaft to be fitted to the first inner body member for passing electrical conductors through the first inner body member. By means of a sleeve shaft, a coaxial pressurized fluid rotary device may be used in connection with the rotation axis of the first inner body part and the second outer body part, because the sleeve shaft allows the rotating device to be positioned extending the first inner body part and In addition, the sleeve shaft allows the pivoting device to be positioned after the first inner body and the second outer body, whereby the first inner body may be wider allowing the fluid medium flow passages to be formed in the first inner body without increasing the overall width of the rotating device.
According to one embodiment, the axial channel is formed as an integral part of the first inner body portion. In this case, the structure of the rotating device can be made without separate attachment or locking between the sleeve shaft and the body part, whereby the structure is very strong and can be manufactured in one piece either by machining or, for example, by casting.
Preferably, the coupling means are adapted to attach said pivoting device to the second outer frame member.
According to another embodiment, the sleeve shaft is a separate part to be attached to the first inner frame member. With a separate sleeve shaft, the properties of the pressure-medium swivel can vary more, since the sleeve shaft can be made to fit different swivel devices without the need for a separate adapter. This in turn increases the modularity of the structure of the rotating device.
According to one embodiment, the second channels are annular annular channels formed on the outer circumference of the first inner body.
Preferably, the structure includes an additional channel for passing fluid through the structure. In this way, the rotating device can also be implemented without the hoses needed to conduct the fluid, which would limit the rotation of the rotating device.
Preferably, the fluid is a carrier treatment agent or lubricant for central lubrication equipment, for example, lubricating oil or grease.
Preferably, the additional channel is formed either on the outer surface of the first inner body portion or on the inner surface of the second outer body member or both. In this case, the auxiliary channel may be circumferential, which allows the carrier treatment medium to be transmitted in all relative positions of the first inner body member and the second outer body member.
Preferably, the pressure medium is hydraulic oil.
Current
20186119 prh 20 -12-2018 harvester head actuators and rotary swivel are generally hydraulic actuators.
According to one embodiment, the pivoting device can also be electric, whereby the driving force it requires can also be applied along an axial channel using electrical conductors.
The connecting means may be provided on the other outer frame member. In this way, the pressurized medium pivoting device is connected to the second outer frame member which is rotatable with respect to the first inner frame member.
Preferably, the bearing means is a circumferential bearing disposed between the first inner frame member and the second outer frame member. Peripheral bearings are easy to replace and there are many manufacturers of perimeter bearings. The circumferential bearing is adapted to carry axial and radial loads between the first inner frame portion and the second outer frame portion of the rotating device.
A leakage line may be formed coaxially around the axial passage to direct the leaks of both the pressurized fluid actuator and harvester head actuators back to the boom through the structure of the rotation device. In this case, the rotation device can be implemented without a separate ring line for leakage. In this context, leakage refers to the internal leakage in the pressure medium engine where the pressure medium is passed past the piston into the housing of the pressure medium engine. This leaked pressure medium should be drained out of the housing to prevent the pressure medium motor from becoming high enough to cause internal damage to the pressure medium motor.
The object of the rotating device according to the invention can be achieved by a rotating device comprising a structure according to the invention, a direct-acting fluid-medium turning device coaxially connected to the structure with respect to the axis of rotation and an adapter for rotating electric conductors connected to the lower surface of the turning device. The rotary device according to the invention can be manufactured modularly using pivoting devices and circumferential bearings of different manufacturers, since the structure can be easily modified according to the components of different manufacturers. In other words, each feature and feature of the rotating device can be implemented in the best possible way and with the most suitable components. The adapter allows the electrical wires to be rotatable.

According to one embodiment, the pivoting actuator of the rotation device is a radial piston motor. For example, a radial piston engine is more accurate than a wing motor for working. In a radial piston engine, the sealing occurs over a long distance on the cylinder casing, whereby its pressure resistance is better than in the wing engine, where the sealing 10 takes place in a line contact between the wing and the cylinder. This makes the radial piston engine more precise to operate and produces higher torque than the wing motor.
According to another embodiment, the pressure medium driven turning device 15 is a wing motor. Also, the wing motor can be mounted directly on the sleeve shaft after the structure, thus maintaining a narrow structure of the rotation device.
Preferably, the turning device is hydraulic. The hydraulics 20 provide a steady power output.
Alternatively, the turning device may also be electrically operated.
An electric swivel requires less wiring than a hydraulic swivel.
Preferably, the rotor of the rotating CAN-or-like adapter is adapted to be fixed to the axial channel of the first inner body member of the structure, allowing for a fixed cable installation. In this way, the electrical conductor 30 in the axial passage cannot be twisted. The adapter rotor is attached to the peripheral part of the hydraulic motor. The CAN adapter can also be selected from adapters from different manufacturers.
The adapter is inductive, capacitive, galvanic or a combination of these. The power supply may be, for example, galvanic connection and data transmission by inductive connection.
The adapter used can be, for example, the COMPACT SLIP RINGS - SRC025 from Penlink AB (SE).
Preferably, in the rotating device, the pivoting device is disposed between the first inner body member and the electrical conductor adapter.
Preferably, a hydraulics leakage line is provided between the structure and the turning device to connect and direct the hydraulic flow from the harvester head to the hydraulic line for the turning device. This avoids forming one additional annular channel in the structure.
It is to be understood in this connection that the first inner body part and the second outer body part can each be elements consisting of one or more parts.
The central lead-through of the rotating device according to the invention can be used to transport the electrical cables and ducts (CAN / Arcnet buses) required for hydraulics, stumpage, communication buses to the harvester head. In addition to the communication paths, an electric power / current / voltage supply can also be applied to the harvester head. Thanks to the structure according to the invention, it is possible to rotate the harvester head indefinitely. The design also allows for modularity in the construction of the rotating device, since the same construction can be used to assemble the rotating device without modification or with only minor modifications to be compatible with different manufacturers of rotary devices, CAN adapters and swivel frames. In other words, the rotation device may be implemented with known components and / or commercially available components. The structure according to the invention is a floating structure, whereby the load is not applied to the hydraulic passage or CAN passage. In this context, buoyancy means that the weight of the first inner body member rests gravely on the pivoting device and the first inner body member is freely rotatable relative to the second outer body member and the lugs of the pivoting device. The design allows the CAN bushing component to be located below the diverter. An advantage of the construction according to the invention is that the rotation device can be operated without the need to be wary or to observe hanging hoses, and also without the risk of cutting the hoses during operation when turning the harvester head. The free rotation of the rotating device brings new opportunities for working, speeding up work and improving productivity. On the other hand, the rotation device according to the invention avoids equipment damage caused by a previously limited angle of rotation which can be caused by inexperience of the user. The structure of the invention is shorter in length overall than the prior art rotary devices.
In addition to the electrical conductors and ducts, pressure medium lines, for example hydraulic guides, can be passed through the central lead-through of the rotating device according to the invention.
Preferably, the pivoting device is mounted in the operating position of the pivoting device below the second outer body of the pivoting device, on the underside of the second outer body. In this case, the attachment of the turning device is simple and the turning device of different manufacturers can be easily used.
One preferred hydraulic turning device which can be used with the structure of the rotating device according to the invention to form the rotating device according to the invention is the turning devices marketed by Bosch Rexroth AG under the trade names MCR5 or MCR10.
In this context, direct drive means that, for example, there is no mechanical transmission between the pivoting device and the first inner member, but rather the pivoting device directly to the first inner body member.
rotates the body
The object of the forestry machine according to the invention can be achieved by a forestry machine having the structure of a rotating device according to one of the above-mentioned embodiments.
Preferably, the forestry machine includes a harvester head. Particularly in connection with the harvester head, there is a need to pass several pressurized fluid streams and possibly also electrical wires through the turning device.
In the rotating device according to the invention, the first inner body part and the second outer body part together form a rotatable assembly which divides the pressure medium flow from the rotating device forward. Below this assembly is preferably mounted a standard coaxial pivoting device comprising an opening for passing an axial channel through the pivoting device. Advantageously, an adapter is provided on the underside of the pivoting device to allow rotation of the electrical conductors.
It is to be understood that the structure and the rotation device of the rotation device according to the invention can also be used in connection with any implement which uses pressure medium, control and / or measurement. In addition to the harvester head, such implements may be, for example, a grapple saw, a feller grapple / device, a lifting device or other similar implement mounted on the end of a boom or other boom. Instead of the boom, the structure of the rotation device according to the invention can also be hung on some other corresponding suspension structure.
The invention will now be described in detail with reference to the accompanying drawings, in which:

As shown in Figure 1, the rotation device 1 according to the invention is preferably adapted for use with forest machines 100. The rotation device may also be referred to as a rotator commonly used in the art. The forest machines 100 generally have a working boom 102, the end of which is rotated by a pivoting device 1, the last boom 2 being the end of the boom. The articulation of the pivoting device 1 to the boom 2 can be made in accordance with the prior art with two transverse pivotal articulations, which allow the pivoting device 1 to always be suspended independently of the position of the working boom 102. The rotation device 1 may be mounted on a pendulum arc 5 belonging to the harvester head 3, which can be rotated unrestrictedly around the axis of rotation of the rotation device 1 by means of the rotation device 1. In accordance with the prior art, the pressurized fluid flow required by the actuators of the harvester head 3 is supplied through the working boom 102 by hoses from the pressure medium pump 106 of the forest machine 100, which is rotated by the engine 104 of the forest machine 100 to create pressure. As shown in Figure 1, the rotary device 1 according to the invention enables the pressurized fluid flows from the working boom 102 to pass through the rotating device 1 to the harvester head 3. Similarly, the electrical control of the harvester head 3 is introduced from the forest machine 100 through the rotating device 1 to the harvester head 3.
According to Figure 2, when using the rotating device 1 according to the invention, pressurized fluid flows through the rotating device 1 are led along lines 60.1 to 60.3 to the valve block 4, from which the flow is further divided to the actuators pruning cylinders.
Preferably, the rotating device of the invention is intended for use in a forestry machine in which the pressure medium is hydraulic oil, but the invention is also applicable for use with pneumatic pressurized fluid streams. It should also be understood that instead of a forestry machine, the rotating device and the construction of the rotating device according to the invention are also suitable for use with, for example, excavators and other working machines with work booms.
The flow of pressure medium flows from the boom 2 to the rotation device 1 shown in Figure 2 can be implemented in several ways. The connections of the pressure medium flow lines associated with the lid 88 of the rotating device 1 shown in Figure 7 may be arranged to run parallel to the rotating device relative to the axis of rotation and toward the second axis of rotation of the boom 1. In other words, the joints connecting the lines to the rotator are oriented upwardly as shown in Figure 2 with respect to the longitudinal direction of the joint. Preferably, the pressurized fluid flows the lines leaving the boom 2, in this case the end of the boom, pass through the pivot joint between the boom 2 and the rotation device 1 and through its axis of rotation. Alternatively, the junctions of the pressure medium flow lines with respect to their longitudinal direction may be at an angle of 5 to 85 ° with respect to the plane of the rotating device cover, i.e. in other words the line joints are inclined at the oblique angle. Alternatively, the junctions of the lines of pressure medium streams may be disposed on the boom facing side of the pivoting device and the lines may pass in the direction of the rotary axis of the harvester head side of the rotary joint The foregoing are merely exemplary ways of conducting a pressure medium flow to a rotating device.
Fig. 3a is a cross-sectional view of a first embodiment of a rotary device 1 and a rotary device structure 10 according to the invention. The rotation device 1 according to the invention includes a structure 10 of the rotation device and a pivoting device 24 attached thereto, and an adapter 48 of the electric conductors 96 shown in Fig. 9. The adapter 48 is preferably secured to the lower surface 94 (shown in Figures 3b and 4b). The pivoting device 24, in turn, is preferably mounted on the lower surface 92 of the second outer frame member 14. In this context, when speaking about the lower surface, the pivoting device is determined by its pivoting position on the opposite side of the pivoting device structure.
The structure 10 of the rotation device 1 comprises, as main components, a first inner frame member 12, a second outer frame member 14, bearing means
20, connecting means 22, axial channel having two ends 16.1 and 16.2, first channels
26, .1 includes an electrical cord holder (not shown). The first inner body member 12 is a cylindrical body through which an axial channel 16 for electrical conductors and first channels 26 for penetrating the pressure medium are formed. The axial duct 16 forms one cylindrical first inner body portion 12 at an opposite end relative to the pivoting device 24 to be attached to the structure of the rotating device 1 and to the outside of the pivoting device 24. The other end 16.2 of the axial duct 16 is the end which is at the end of the first inner body part 12 to which the pivoting device is adapted to be fastened.
In the embodiments of Figures 3a to 4b, the first passageways 26 are provided for passing three different pressurized fluid streams through the first inner body member 12. Preferably, the first channels 26 are axial with respect to the first inner body member 12, i.e. parallel to the axial channel 16, and each of the first channels 26 has two ends. The first of the ends of each of the first passageways 26 forms one end of a cylindrical first inner body portion 12 which is opposite to the pivoting device 24 to be attached to the structure of the rotation device 1. The other end, in turn, forms the first inner body portion radially to the side. The first channels 26 may also be slightly inclined relative to the longitudinal direction of the first inner body portion 12, whereby the second ends of the first channels 26 form directly together on the sides of the first inner body member. In Fig. 3a, with respect to the axial channel 16, the first left channel 26 is a thrust line, while the first right channel 26 is a return line. The first passageways 26 and the axial passageway 16 may be 2 to 50 mm in diameter and preferably of circular cross-section. Preferably, channels 26 and 16 are 15 to 30 mm in diameter for optimum volume flow.
In the embodiment of Figures 1-9, the first inner frame member 12 is intended for hanging the rotation device 1 on the boom 2 of the forestry machine by means of the associated suspension means 90. In this embodiment, lugs 54 are formed in the first inner frame member 12 as suspension means 90, which in turn have openings 50 for hinging the rotation device 1 to the boom 2 of the forestry machine.
The second outer body portion 14, in turn, is preferably formed as a sleeve-like structure which is fitted radially over the first cylindrical first inner body portion.
Between the first inner body member 12 and the second outer body member, there are bearing means 20 which allow the first inner body member 12 and the second outer body member to rotate relative to one another. If the rotation device is suspended as in Figs. 1-7, i.e. from the first inner frame 12 to the boom 2, the first inner frame 12 is held in place while the harvester head 3 rotates and the second outer frame portion 14 is mounted on the first inner frame 12.
The bearing means 20 is preferably a circumferential bearing 40, which has the advantage of being easily replaceable and of a plentiful supply from manufacturers. Preferably, the bearing means comprises a bearing and a toothing arranged to allow rotation of the second outer body member 14 with respect to the first inner body member 12 and vice versa. As previously stated, the bearing means 20 are adapted to carry axial and radial loads.
Axial loads are created by the load of the harvester head, which is transmitted mainly as a vertical load through one of the outer frame members 14 and thereby to the bearing means 20 of the pivoting device 24.
The second outer body member 14 also includes its radially oriented connections 28, which are intended to guide the pressure medium from the first inner body member 12 through the second outer body member 14. Preferably, the connections 28 are as many as the first passageways 26. In order to connect the connections in each of the rotational positions of the first inner body and the second outer body, the outer surface of the first inner body or the inner surface of the second outer body other channels. In the embodiments of Figures 3a to 4b, the second passageways 30 are formed on the outer surface 32 of the first inner casing 12, and the inner surface of the second outer casing is illustrated by reference numeral 34. Each second passage 30 is preferably a circumferential annular passage in spite of the relative position of the second outer body portion 14. In other words, each second channel is a continuous annular radial recess in the first inner body member, the second outer body member, or both. As shown in Figures 3a to 4b, second passages 30 are preferably as many as first passages 26 and connectors 28. Preferably, rotary seals are formed on the first inner body member or the second outer body member to prevent pressure medium from leaking from the second inner body member and between the second outer frame member. The rotary seals 70 are formed in the embodiment of Figures 3a to 4b on the first inner body member 12.
The coupling means 22 are arranged to connect a direct drive fluid-pressure pivoting device 24 to be coaxially connected with respect to the axis of rotation between the first inner body part 12 and the second outer body part 14 for transmitting torque. In this context, direct drive means that the force is preferably applied directly to the first inner body 12, for example by means of a sleeve shaft 36. The pivoting device 24 together with the structure 10 forms the pivoting device 1 according to the invention. Preferably, the connecting means 22 are arranged to attach said pivoting device 24 to a second outer frame member 14, wherein the pivoting device 24 is fixedly attached to the second outer frame member 14.
Preferably, the structure 10 includes a sleeve shaft 36 formed with transmission means 76. The sleeve shaft 36 may be a separate shaft passing through the first inner body portion 12 in which said axial channel 16 is formed, as shown in Figures 3a and 3b. 3a and 3b can be secured to the first inner body 12 by a form-locking engagement, for example by means of boron 74 (more particularly in Figure 8), and transmitting the torque 24 to the first inner body 12 by rotating the second outer body 14 to the first inner body section 12. On the other hand, it is also possible to attach the sleeve shaft 36 to the first inner frame member by means of a frictional connection, for example a thermal connection. The sleeve shaft 36 may be of such a length that it extends both along the first inner body portion 12 and at least partially along the pivoting device 24 attached to the structure 10. Preferably, the transmission members 76 formed on the sleeve shaft 36 are also borons which transmit torque between the pivoting device 24 and the first inner body member 12. As the rotation device 1 is rotated, the first inner body member 12 and the sleeve shaft 36 attached thereto remain in position while the pivoting device 24 and the second outer body member 14 attached thereto rotate. At the end of the pivoting device 24 of the sleeve shaft 36, second connecting means 78 are provided which allow a separate electrical conductor adapter 48 to be connected to the end of the sleeve shaft 36. 4a and 4b, the sleeve shaft 36 may be formed as an integral part of the first inner body member 12, the sleeve shaft 36 being a structure projecting from the first inner body member 12 with an axial channel 16 for electrical conductors extending in the center thereof.
The axial duct 16 allows the electrical conductors from the boom to be routed through the rotating device 1 to the end 16.2 of the axial duct 16 at the pivoting end 24.2 at least at the end 16.2 through the first inner body 12 and the pivoting device 24 fitted to the pivoting device. In order to prevent electrical wires from preventing rotation of the rotating device, the electrical wires must preferably be connected to the electrical conductor adapter 48 included in the rotating device. The adapter 48 is rotatable so that electrical wires can be rotatably secured to the upper part of the adapter The adapter can be any circular adapter on the market. Preferably, the electrical wires to be passed through the rotating device of the invention are communication buses, preferably CAN bus or ArcNet bus, and adapter 48 is a CAN adapter or Arcnet adapter, respectively. The CAN bus or ArcNet bus provides electrical control of the harvester head actuator functions, measurement sensors and valve controls on the harvester head. There may also be more than one electrical conductor. For the adapter 48, the rotating device 1 may also include a protective cover 52, which may be attached to the pivoting device 24. The adapter to be connected under the pivoting device contributes to a lower and simpler structure than prior art rotating devices.
The pivoting device used in the rotating device according to the invention is preferably a pivoting device coaxially disposed about the sleeve axis, the axial channel 16 parallel to the pivoting axis of the pivoting device being adapted to extend through the structure and at least partially to the length of the pivoting device. In this case, the pivoting device can be implemented so that it does not widen the pivoting device laterally. Preferably, the pivoting device 24 used in the rotating device 1 is a hydraulic radial piston motor 42. The advantages of the radial piston motor are its precise operation and good service life, since it is sealed by the rotary movement of the bearings. Alternatively, the pivoting device may also be a wing motor, which may also be fitted directly around the sleeve shaft.
According to the embodiments of Figures 3a to 4b, the structure 10 of the rotor 1 according to the invention may also include one additional channel 80 formed by the first channel 26, the second channel 30 and the joint 28 for passing fluid through the rotating device 1. The fluid may be, for example, a carrier treatment inhibitor or a lubricant, for example a lubricating oil or grease. Commonly used as a barrier agent, urea is used in a forestry machine when felling wood for stump treatment. When the tree is felled, the tree stump is left open, whereby the open wood surface is easily exposed to parasitic attack, for example by rotting fungus. The decay fungus can spread through the roots of the stump to other healthy trees, destroying the tree stump.
In the embodiment of Figures 3a and 3b, in which the sleeve shaft 36 is a part separate from the first inner body member 12, one of the first channels 26 may be formed between the sleeve shaft 36 and the first inner body member 12, coaxially around the sleeve shaft 36. In other words, there is an empty space between the sleeve shaft 36 and the first inner body part 12, along which the leakage of pressure medium flow from both the turning device 24 and the harvester head can be passed through the rotating device 1. This avoids the use of one additional second channel and two rotary seals in the structure.
Fig. 5 shows a rotating device 1 according to the invention separately from a forestry machine. In the figure, the pressure media lines 60.1, 60.2 and 60.3 are connected to the joint 28 and connected to the harvester head. Of these, the pressure medium line 60.1 is preferably the pressure line, 60.2 return line and 60.3 leak line. Below the pressure medium lines 60.1, 60.2 and 60.3 are shown the connections 62 for directing the fluid medium flow from the harvester head to the turning device 24. Reference numeral 46 denotes holes through which the rotating device can be bolted to the hanger arc 5 of the harvester head 3 as shown in Figs. In Figure 5, reference numeral 56 illustrates electrical conductors. In turn, hose 82 is a barrier line for carrier treatment arranged as an auxiliary fluid.
Figure 6 shows in more detail the connections 28 to which the pressure medium lines 60.1, 60.2 and 60.3 of Figure 5 are connected. The figure also shows the connections 62 of the pivoting device 24, which, as shown in Figure 2, connect the pressure medium lines 62.1 to 62.3, of which the pressure medium lines 62.1 and 62.2 are the pressure line and return line and the middle pressure medium line 62.3 is the leak line. Reference numeral 86 denotes a barrier line assembly.
Fig. 7 is a top view of a rotating device 1 according to the invention. In this embodiment, the cover 88 of the rotating device 1 is formed for the first channels 26 and the axial channel 16. Here, the first diameter 26 of the smaller diameter, to the right of the axial channel 16, is a barrier line. The one below the axial duct 16 in the figure is the pressure medium flow pressure line, the one above the return line and the left one the leak line. It should be understood, however, that the different first channels may be used for different purposes, i.e. the pressure line, the return line and the leak line may be in different order.
Fig. 8 is an exploded view of the rotating device 1 according to the invention. 8, the first inner body portion 12 preferably comprises two parts 12.1 and 12.2, of which, in this embodiment, the first channels 26 and the second portion 12.2 include second channels 30. The rotation device 1 also includes a lid 88 which can be secured to the first inner body. In the third embodiment of the rotating device 1 and the rotating device structure 10 in Figure 8, the first channels 26 are extended by extension channels formed in the cover 88, which rotate the connections for pressure fluid flow hoses substantially 90 ° relative to the orientation of the first channels. Thus, the hoses extend from the lid 88 of the rotating device 1 to the side, unlike in the embodiments of Figures 1-7. As shown in Fig. 8, a plurality of parts are secured to each other by bolts or other locking means, whereby the rotation device can be disassembled as required. Figure 8 shows the portions of the peripheral bearing 40 illustrated by reference numerals 40.1 and 40.2.
Unlike the embodiments of Figs. 1, the rotation device of the invention can also be made such that the second outer frame part of the rotation device structure is connected to the lugs and thereby to the boom, while the harvester head is secured to the first inner frame part.
Figures 9 and 10 show a fourth embodiment of the frame structure of a rotary device according to the invention. In contrast to the embodiment of Fig. 8, the inner body part 12 is a solid body and does not comprise two parts 12.1 and 12.2 as the embodiment of Fig. 8. The location of the pressure line 60.1, the return line 60.2 and the leak line 60.3 has been changed in the embodiment of Figure 9 relative to the embodiment of Figure 8. 9, the leakage line 60.3 is formed between the inner body member 12 and the axial channel 16. Figure

The rotating device and the structure of the rotating device according to the invention are preferably made of steel or similar material suitable for the application, except for various seals. The rotation device according to the invention may have a height of 300 to 800 mm and a diameter of 200 to 400 mm, preferably 250 to 350 mm. The weight of the rotating device 10 may be in the order of 50 to 200 kg, preferably 100 to 150 kg, due to the optimum power to weight ratio. The bearings to be used can, as is known per se, preferably be roller bearings, such as needle, ball, roller or tapered roller bearings, or more preferably circumferential bearings. On the other hand, the bearings 15 may also be plain bearings, whereby they bear the same loads as the circumferential bearing, and in which the material may be bronze bearing, brass or a polymer.
A variant of the solution shown in Figures 3a-4b (not according to the invention) 20 would be one in which no center channel or rotary adapter is needed at all when the required electrical energy is generated in the harvester and communication is wirelessly provided to the harvester head from the hanging device. It is also possible to move the rotating adapter 25 above the pivoting device, which, however, is the use of standard components if the hook fish is to be used.
