Technical Field
[0001] The present invention relates to forestry operation machinery, and more particularly to attaching a harvester head to the end of a cantilever of a forestry operation machinery. Background Technology
[0002] In forestry machinery, the harvester head is attached to a hook-and-loop bow-shaped component at the end of the cantilever. The harvester head can be rotated by a rotating body located at the end of the cantilever. Typically, this device is of a specific type in forestry machinery. Utility Model Content
[0003] The purpose of this invention is to develop a novel device and adapter plate for attaching a harvester head to the end of the cantilever of a forestry machine. The solution according to this invention is characterized by what is disclosed in the main aspects. Various embodiments of this invention are disclosed in other aspects.
[0004] In the proposed solution, the harvester head is attached to the end of the cantilever of a forestry machine using a specific device. This device includes a hook, a rotating body, a hook-shaped bow on the harvester head, and an adapter plate. The hook can be attached to the cantilever, and the rotating body can be attached to the hook. The harvester head includes a hook-shaped bow that can be attached to the rotating body. The hook-shaped bow includes attachment points for the rotating body. The adapter plate can be attached to the attachment points of the rotating body located in the hook-shaped bow, and the adapter plate includes attachment points for attaching the rotating body to the adapter plate. Thus, the rotating body can be directly attached to the hook-shaped bow of the harvester head without the adapter plate, and conversely, the rotating body can be attached to the hook-shaped bow of the harvester head using the adapter plate. The rotating body directly attached without the adapter plate can differ from the rotating body attached using the adapter plate. Therefore, different rotating bodies can be attached to the hook-and-loop bow of the harvester head without any adjustment to the structure of the hook-and-loop bow. Thus, there is no need to select the hook-and-loop bow based on the type of rotating body.
[0005] According to one embodiment, the hook-and-loop bow includes, for example, a through-hole for a portion of the rotating body frame and / or for hoses and cables. In this case, an adapter plate can be arranged to connect to the through-hole in the hook-and-loop bow. When the adapter plate is not arranged to connect to the through-hole, for example, a portion of the rotating body frame can be arranged to pass through the hook-and-loop bow and / or the required hoses and cables can pass through the hook-and-loop bow. Then, for example, a rotating body or some other type of rotating body that requires a larger equivalent through-hole than usual can be arranged on the hook-and-loop bow. On the other hand, when using an adapter plate, it is easy and simple to arrange to connect to the through-hole in question.
[0006] According to one embodiment, the attachment points of the rotating body in the hook-and-loop bow-shaped member are arranged around the through-hole of the hook-and-loop bow-shaped member. The attachment points of the adapter plate can be formed to correspond to the attachment points of the rotating body arranged around the through-hole of the hook-and-loop bow-shaped member. In this way, when the rotating body is attached to the hook-and-loop bow-shaped member without the adapter plate, the rotating body can be arranged centered relative to the through-hole. On the other hand, if necessary, the adapter plate can be attached centered relative to the through-hole.
[0007] According to an embodiment, the attachment points of the hook-and-loop bow are configured to attach a rotating body to the hook-and-loop bow. The attachment points of the adapter plate can be configured to correspond to the attachment points of the hook-and-loop bow, which are configured to attach the rotating body to the hook-and-loop bow. Thus, when the adapter plate is not used, the rotating body can be attached to the hook-and-loop bow. Alternatively, the adapter plate can be precisely attached again to the same point where the rotating body will be attached. The adapter plate may include attachment points for attaching non-rotating bodies to the adapter plate. Preferably, the rotating body can be attached to the hook-and-loop bow without the adapter plate, and the non-rotating body can be attached to the hook-and-loop bow with the adapter plate. The difference in attaching different types of rotating bodies lies only in the use or absence of the adapter plate. Therefore, this solution is very clear, simple, and reliable.
[0008] According to one embodiment, the adapter plate includes a bracket for supporting hoses and cables and / or supports for hoses and cables. The hoses and cables can then be easily and simply supported. In this case, the hook-and-loop bow-shaped member does not require, for example, a structure for supporting the hoses and cables. On the other hand, when using a rotating body, such as a slewing rotating body, a structure for supporting the hoses and cables is generally not needed, wherein the hoses and cables are arranged inside the rotating body from the cantilever to the harvester head. Therefore, the need for supporting hoses and cables is closely related to the need for using an adapter plate, thus it is practical to arrange the structure for supporting hoses and cables to connect with the adapter plate.
[0009] According to one embodiment, the frame portion of the adapter plate includes an opening. The opening in the frame portion reduces the structural bulk of the adapter plate. Furthermore, the opening in the frame portion of the adapter plate allows hoses and cables to pass through the adapter plate, and, if necessary, also allows the passage of hook-and-loop bow-shaped components.

[0021] Reference Figure 1 , Figure 1 Forestry operation machine 1 is shown. Forestry operation machine 1 can be, for example, such as... Figure 1 The image shows a harvester. Forestry machinery, especially mobile forestry machinery. Forestry machinery can also be a combination of a transport machine and a harvester.
[0022] The body 2 of the forestry operation machine 1 may include one or more body parts and a cantilever 3 mounted to at least one body part. In this specification, the term cantilever 3 is also used to refer to a cantilever structure including more than one cantilever.
[0023] The forestry operation machine 1 also includes tools arranged to the cantilever 3. These tools may include, for example, tree-handling tools such as a harvester head 4 or a grabber. In this document, the term harvester head 4 also includes a felling head and a processing head. The forestry operation machine 1 may be body-turning, and the forestry operation machine 1 may include at least two body parts.
[0024] According to embodiments, the forestry operation machine 1 may also include other structural elements. For example, the forestry operation machine 1 may include a compartment 5 disposed to at least one body part. The forestry operation machine 1 may also include a moving device 6, which may include at least one of the following: wheels disposed on an axle, wheels disposed on a swing axle, wheels disposed on a tandem axle, a track system, or some other known device for controlling the movement of the forestry machine relative to its working surface. It will be apparent to those skilled in the art that, depending on the type of forestry operation machine 1, the forestry operation machine 1 may also typically include many additional structural and functional structural parts and entities, such as a power source 7, etc. On the other hand, the forestry operation machine 1 may also be a tractor equipped with a harvester head 4 or an excavator equipped with a harvester head 4.
[0025] The harvester head 4 includes a hook-and-loop bow-shaped component 8. The harvester head 4 is attached to the hook-and-loop bow-shaped component 8 to a rotating body 9. The rotating body 9 causes the harvester head 4 to rotate.
[0026] The rotating body 9 is attached to the hook 10 from its upper bracket. The hook 10 is attached to the end of the cantilever 3. The hook 10 then serves as a connector between the rotating body 9 and the cantilever 3. The hook 10 may be a braking hook, equipped with one or two brakes to suppress the oscillation of the rotating body 9.
[0027] For clarity, Figure 1 Hose, such as hydraulic hose, and cable connected to cantilever 3 and leading to harvester head 4 are not shown.
[0028] Figure 2 A device is shown in which the harvester head 4 is attached to the end of the cantilever 3. Figure 2 In this embodiment, the rotating body 9 is rotary. The fact that the rotating body 9 is rotary means that the rotating body 9 can rotate the harvester head 4 relative to the end of the cantilever 3 by more than 360°.
[0029] Figure 2 A hose 11 is shown extending from the cantilever 3 to the upper portion of the rotating body 9, and from the lower portion of the rotating body 9 to the harvester head 4. The hose 11 may be, for example, a hydraulic hose and / or a hose for conveying other fluids. A rotary connector is located between the upper and lower portions of the rotating body 9, in the middle of the frame of the rotating body 9, enabling the conveyance of hydraulic media or other fluids between the upper and lower portions of the rotating body 9 that rotate relative to each other. The cable from the cantilever 3 to the harvester head 4 is also conveyed in a corresponding manner.
[0030] For clarity, Figure 3 The hose or cable is not shown. Therefore, Figure 3 The connector 12 to which the hose 11 is attached is shown.
[0031] Because, for example, hydraulic fluid and cables are conveyed through the rotating body 9, the diameter of the frame of the rotating body 9 is quite large. Furthermore, the structure of the rotating body 9 allows its frame to continue below its attachment point. Therefore, the attachment point 13 of the rotating body 9 in the hook-and-loop bow 8 is located on a fairly large arc. The hook-and-loop bow 8 includes a through-hole 14 around which the attachment point 13 of the rotating body 9 is arranged. The through-hole 14 of the hook-and-loop bow 8 is formed at a point on the axis of rotation of the rotating body 9.
[0032] The through-hole 14 of the hook-and-loop bow 8 can be arranged such that a portion of the frame of the rotating body 9 can be arranged to pass through the hook-and-loop bow 8. In this way, the rotating body 9 can be securely connected to the hook-and-loop bow 8. In a preferred embodiment, the through-hole 14 of the hook-and-loop bow 8 can also be used to deliver hoses and / or cables through the hook-and-loop bow 8.
[0033] The rotating body 9 is attached to the hook-and-loop bow 8. The attachment point 13 of the hook-and-loop bow 8 includes attachment devices for attaching the rotating body 9 to the hook-and-loop bow 8. The attachment devices discussed may include, for example, holes in the hook-and-loop bow 8 and holes in the frame of the rotating body 9, bolts fitted into the holes, and nuts fitted into the bolts. Alternatively, the attachment devices may be other types of devices, such as threaded rods attached to the frame of the hook-and-loop bow 8 or the rotating body 9, which may correspondingly fit through holes in the frame of the rotating body 9 or holes in the hook-and-loop bow 8 and may be bolted into place, or these holes may be threaded so that bolts can be quickly and directly screwed into the holes without the use of bolts, or other locking methods other than nuts connected to bolts or rods may be used, or other attachment devices suitable for this purpose may then be used.
[0034] Figure 9 The attachment of the rotating body 9 to the hook-and-loop bow-shaped part 8 is shown. Figure 9 Also shown is a portion 9a of the rotating body 9 attached to the hook 10 and a portion 9b of the rotating body 9 attached to the hook bow 8. Figure 9 Also shown is bolt 22, by means of which the rotating body 9 is attached to the hook-and-loop bow 8. A portion of the frame of the rotating body 9 extends through the hook-and-loop bow 8. In the rotating body 9, the portion 9a of the rotating body 9 attached to the bow 10 is rotatable relative to the portion 9b of the rotating body 9 attached to the hook-and-loop bow 8. Therefore, the hook-and-loop bow 8 is rotatable relative to the hook 10.
[0035] Figure 4 Another device is shown, by means of which the harvester head 4 is attached to the end of the cantilever 3. Figure 4 In this embodiment, the rotating body 9 is non-rotating. The fact that the rotating body 9 is non-rotating means that the rotating body 9 can cause the harvester head 4 to rotate less than 360° relative to the head of the cantilever 3.
[0036] exist Figure 4 and Figure 5 In the embodiment, the hook and loop bow-shaped component 8 and Figure 2 and Figure 3 The hook-and-loop bow-shaped component 8 is the same as in the embodiment. Furthermore, Figure 4 and Figure 5 In the embodiment, the hook 10 can be with Figure 2 and Figure 3 The hook and loop 10 in the embodiment is the same.
[0037] exist Figure 4 and Figure 5 In this embodiment, the hook-and-loop bow-shaped member 8 is attached to the adapter plate 15. The rotating body 9 is then attached to the adapter plate 15. Figure 6 It shows the relationship with Figure 4 and Figure 5 The device is equivalent to the device. However, Figure 6 The apparatus is illustrated as an exploded view.
[0038] The adapter plate 15 includes a first attachment point 16 for attaching the adapter plate 15 to the hook and loop bow 8. The first attachment point 16 of the adapter plate 15 is located at a position corresponding to the attachment point 13 of the rotating body 9 in the hook and loop bow 8. The adapter plate 15 includes a second attachment point 17 for attaching the rotating body 9 to the adapter plate 15.
[0039] Therefore, the attachment point 13 of the hook-and-loop bow 8 corresponds to the first attachment point 16 of the adapter plate 15, and the attachment point includes an attachment device for attaching the adapter plate 15 to the hook-and-loop bow 8. The attachment device in question may include, for example, holes in the hook-and-loop bow 8 and holes in the adapter plate 15, bolts 22 fitted into the holes, and nuts fitted into the bolts. Alternatively, the attachment device may be some other type of device, such as those described above.
[0040] The second attachment point 17 of the adapter plate 15 includes attachment means for attaching the non-rotating body 9 to the adapter plate 15. The attachment means may include, for example, holes in the adapter plate 15 and holes in the frame of the non-rotating body 9, bolts 22 fitted into the holes, and nuts fitted into the bolts. Alternatively, the attachment means may be some other type of device, such as those described above.
[0041] Figure 4A hose 11 is shown extending from the cantilever 3 to the harvester head 4. The hose 11 may be, for example, a hydraulic hose and / or a hose for conveying other fluids, such as residual dry treatment agents.
[0042] Hose 11 is attached to bracket 18. Hose and / or cable can be fitted to bracket 18. Bracket 18 is attached to bracket 19 located in adapter plate 15. Cable from cantilever 3 to harvester head 4 can also be delivered in a manner corresponding to hose 11.
[0043] For clarity, Figure 5 The hose or cable is not shown. Therefore, Figure 5 The bracket 19 of the adapter plate 15 is shown, to which the bracket 18 can be attached.
[0044] The diameter of the non-rotating rotating body 9 is typically smaller than that of the rotating rotating body. Therefore, it is impossible to attach the non-rotating rotating body 9 to the hook-and-loop bow 8 using attachment point 13. The through-hole 14 of the hook-and-loop bow 8 can also be large enough that its diameter is larger than that of the non-rotating rotating body 9. The adapter 15 is larger than the through-hole 14, thereby allowing the adapter plate 15 to be attached to the hook-and-loop bow 8 such that the adapter plate 15 at least primarily covers the through-hole 14. The second attachment points 17 of the adapter plate 15 are arranged such that the non-rotating rotating body 9 can be attached to the adapter plate 15 using them. In this way, the non-rotating rotating body 9 can be attached to the hook-and-loop bow 8 via the adapter plate 15.
[0045] For example Figure 7 As shown, the adapter plate 15 may include an opening 20 in its frame portion. The opening 20 reduces the structural bulk of the adapter plate 15. Furthermore, in a preferred embodiment, the opening 20 may serve as a through-hole for hoses and / or cables. For example, in some rotating bodies, hoses and / or cables may be conveyed via the bottom of the rotating body, whereby it is advantageous for the adapter plate 15 to include the opening 20, and the hook-and-loop bow member 8 to include a through-hole 14.
[0046] Figure 10 The attachment of the non-rotating rotating body 9 to the hook-and-loop bow-shaped part 8 is shown. Figure 10 Also shown is a portion 9a of the rotating body 9 attached to the hook 10 and a portion 9b of the rotating body 9 attached to the adapter plate 15 and attached to the hook bow 8 via the adapter plate 15. Figure 10 It is also shown that the rotating body 9 is attached to the adapter plate 15 by bolts 22, and the adapter plate 15 is attached to the hook and loop bow 8 by bolts 22. In the rotating body 9, the portion 9a of the rotating body 9 attached to the hook and loop 10 is rotatable relative to the portion 9b of the rotating body 9 attached to the adapter 15 and attached to the hook and loop bow 8 via the adapter 15. Thus, the hook and loop bow 8 is rotatable relative to the hook and loop 10.
[0047] The bracket 19 of the adapter plate 15 may include one or more holes 21 to allow the bracket 18 to be easily, reliably and simply attached to the adapter plate 15. The bracket 15 may be attached to the adapter plate by a simple bolted connection or some other attachment method suitable for this purpose.
[0048] like Figure 8 As disclosed, the bracket 19 of the adapter plate 15 is arranged at an angle α relative to the frame portion of the adapter plate 15. The angle α discussed can be, for example, in the range of 20° to 50°. When the bracket 19 is at an angle relative to the frame portion of the adapter plate 15, the bracket 18 can be easily and simply attached to the bracket 19, for example, by bolts and nuts. The angled bracket 19 also provides working space for attaching the bracket 18 to the bracket 19. Threads can be formed in the holes 21 of the bracket 19 to further facilitate the attachment of the bracket 18 to the adapter plate 15. In general, because the bracket 19 of the adapter plate 15, and especially the bracket 19, is at an angle, hoses and / or cables can be smoothly fitted to connect with the hook-and-loop bow 8.
[0049] In the solution shown in the figure, the adapter plate is configured for use in a device for attaching a harvester head to the end of the cantilever of a forestry operation machine, particularly a harvester. An equivalent adapter plate can also be used, for example, in a device for attaching a gripper to the end of the cantilever of a transport vehicle or an equivalent forestry operation machine.
[0050] Those skilled in the art will find that, obviously, the basic concept of this invention can be implemented in many different ways as technology advances. Therefore, this invention and its embodiments are not limited to the examples described above, but can vary within the scope of the claims.
