The technical field
The invention relates to a device delimbing blades for cutting branches on the tree trunks. The invention also refers to the cutting device for felling and cutting branches on the tree trunks.
Description of the prior art
For processing trunks of trees cutting is used, the device whose purpose is to embrace growing up the tree, cut off the tree and fling him. After that cutting device cuts off the branches on the tree trunk and cuts it into pieces fixed length. Usually cutting device is mounted by means of hinges on the end of the crane forest machines. Manufacturing machine is, in particular, harvester, which moves through the landscape through the wheels or tracks. Some cutting device can also be used for loading of the gun on the forwarders used as harvesters, they also provided gripping elements made with the possibility of rotation about a frame design, pairs from different sides of the trunk. Seizure may also consist of gripping elements for cutting branches. Cutting device contains the necessary drives, usually hydraulic cylinders and hydraulic engines that can be used to control the position and the different functions cutting device. Device attached to the end of the crane forest machines usually by means of a rotary device, and the device can be rotated around the vertical axis of rotation.
Cutting device, which is also called the harvester head or cutting head, usually contains at least upper gripping elements, which are usually two and which is attached to a frame design cutting device with the possibility of rotation. Gripping elements are usually placed on opposite sides of a tree trunk. Usually capture elements contain also delimbing blades for cutting branches at a time when the barrel is held and served through the device. Cutting device can also contain a second, lower couple gripping elements or the single intercepting element, which is equipped with equipped with a blade. Feed items are usually contain two of the pickup roller or feed pulleys which are pressed to the trunk and dragged it past delimbing blades and through the device due to friction. Feed items are usually placed on opposite sides of a tree trunk. Cutting device has also a cross-cutting devices, such as chain saw, to perform a cut tree trunk for felling and sawing it into parts fixed length.
Harvester head is described in US 5 785 101. Another harvester head is described in US 6 318 425 B1. Forest machine with the harvester head, mounted on the end of the crane described in WO 03/096794 A1. You can also collect a certain number of trees at small sizes cutting device, which uses collecting devices, which are connected with the cutting device and used together with gripping elements that encircle the tree. Collecting device described in WO 01/10190 A1.
Usually equipped with a blade also attached to a frame design cutting device for cutting branches of the tree trunk, to complement the function of other delimbing blades. Delimbing the blade is usually placed on the front surface of a frame design cutting device. Mentioned delimbing blade is used for cutting branches that side of the tree trunk, which can't get delimbing blades gripping elements. Delimbing blade can be either fixed or movable, with delimbing blade can take the rough surface of a tree trunk. Examples moving delimbing blades are disclosed in US 4 542 194, US 5 732 754.
During knotting delimbing blade exposed to a lot of effort, thus the design should be durable and reliable, and also the device for moving delimbing blades must be insensitive to shock and pollution. Some tree species lower part of the tree trunk free of branches, where there is no need to use delimbing blades. In many cases, it is necessary to trim the branches only at the top of the tree. In addition, solid wood species such as oak, beech, walnut, there is a possibility that the form of tree trunks varies greatly. You do not want delimbing blades crashed into a tree trunk and causing unnecessary damage to the stem because of its curvature or form. The same trunk of the tree has branches that should be trimmed so that delimbing blade was available.
According to a previous level is used turning delimbing blade, cutting edge which by moving delimbing blades can be moved further away from a tree trunk than usual. Delimbing the blade is connected by a hinge with the mentioned front surface, used as a drive cylinder continues through the hole in the front surface, and the first end of the cylinder is connected to delimbing blade to move equipped with a blade in different positions. Cylinder essentially parallel to the tree trunk. The rotation axis of the hinge transverse to the longitudinal direction of the tree trunk. Obviously, this accommodation drive complicates the location of the other elements and drive behind the front surface. It is almost impossible to add this blade in the old device. From the point of view of maintenance, it is difficult to have access to the connection on the other end of the cylinder and connect the hose to a cylinder. In addition, hoses occupy space and must not be damaged.
Summary of the invention
The purpose of the present invention is to eliminate the above drawbacks.
The device delimbing blades according to the present invention will be described in paragraph 1 of the claims. Cutting device for felling and cutting branches of tree trunks according to the present invention will be described in paragraph 4 of the claims.
According to the invention delimbing blade can be moved to a position in which the cutting edge delimbing blades is not the tree-trunk, and is farther from a tree trunk. This provision can be named rejected by the position in which the cutting edge is not easy coincides with the form of tree trunk. Delimbing the blade is connected with the cutting device can be rotated, with delimbing the blade is made with the possibility of a return to its normal position when it comes to a branch that must be cut. The mentioned branch pushes delimbing the blade so that you do not need another external power; and the operator cutting device is not required to control the position of delimbing blades.
If necessary, delimbing blade may be, in control of the operator or even automatically moved to a different position by means of the drive. Normal position can be used all the time, for example, during the cutting branches of pine, spruce or birch. Rejected position delimbing blades can be used in connection with the processing of almost all used tree species, in particular, if the lower part of the trunk of the tree free from the branches. In one example delimbing blade mounted on frame cutting device, not on the drive while cutting branches. The function of an actuator is to move equipped with a blade in a different position, the actuator can be small and to develop a small effort.
In one example, the design, educated delimbing blades and the drive was manufactured especially compact and at the same time the drive was well protected inside this structure. Furthermore, the design is fine, so the size of the cutting device does not become too large. Optimal placement hinge design makes it possible that the entire drive, together with delimbing blades, may be placed on the front side of the front surface of the cutting device. Delimbing blade and the drive easy to maintain. Easier than before to place other elements and drives behind the front surface, especially the cross-cutting device intended for cutting the top.

Hanging lever can be mounted on the back side of the frame and contain only one lever design. Figure 1 hanging lever 6 has the form of a fork, continuing to both sides of the frame 2. Drives cutting devices are managed through an environment under pressure known as such by the way and this is usually the actuators are driven hydraulically operated and controlled by a circuit valve distribution, known as such. In addition, the principle of operation of a gripping elements and feed items known as one of the devices of this type.
On figa and 2A delimbing blade 12 is in the normal position And where delimbing blade 12 slides along a trunk 13 and ready to trim the branches. Delimbing blade has 12 surface 12b (see FIGU), which is essentially parallel to the barrel 13, located on the trunk 13 and should form the trunk 13. Cutting edge 12A is at the forefront of the surface 12b, but it is also possible to place the cutting edge 12A against the trunk 13 slightly higher than the surface 12b. It is also possible to place and surface 12b, and cutting edge 12 above, the regulation for figa than those bearing surface of a frame 2, which pressed the barrel 13. The mentioned distance will determine the gap between cutting edge 12A and trunk 13. The front edge of the surface 12b equipped with cutting edge 12A, which truncates the branches. Cutting edge 12A can also crash into the roughness of the trunk 13. Delimbing blade 12 installed at the front surface 12A in frame 2, with the front surface takes the pressure which affected delimbing blade 12.
On fig.1b and 2b delimbing blade 12 is rejected the position in which the cutting edge 12A is at a distance Y from the trunk 13. The mentioned distance Y now more than at normal position A. The mentioned distance Y supported so that the cutting edge 12A is higher than the bearing surface of a frame 2, which pressed the barrel 13. The mentioned distance Y more than the above mentioned gap. In another example, mentioned the distance Y is provided so that the cutting edge 12A is higher than the place of a surface 12b, who held the barrel 13. Trunk 13, thus, is kept at the rear of 12C or rear edge of the surface 12b, if the surface 12b placed at an angle with respect to the trunk 13, when equipped with a blade 12 is rejected position Century Rear 12C preferably equipped with a rounded bevel or other forms, which takes into account movements of the trunk or, if necessary, also preserves the rear at a sufficient distance from the trunk, when equipped with a blade 12 is rejected position.
According to the example on fig.1b and 2b, delimbing blade 12 is in position, turned forward with hinge 19, and not relied on the front surface 2A. Delimbing blade 12 rotated from frame 2 and raised in relation to the trunk 13, which moves to the left in his longitudinal direction H.
Delimbing blade contains 12 hinge 19, by which delimbing blade 12 is mounted on frame 2 with the possibility of rotation. Frame 2 contains a tool such as eyes, which is mounted delimbing blade 12, for example, by means of the shaft. The rotation axis Z hinge 19 is transverse to the longitudinal direction X barrel. Forked delimbing blade 12 contains two parallel plug 12d and 12th, between which there are placed the drive 15. Hinge 19 placed at the end of the said forks. First hinge 17 of the drive, which is connected with delimbing blade 12, and the second hinge 16 drive which is connected to the frame 2, placed between the forks 12d 12e. For the second hinge 16 frame 2 is equipped with features such as eyes, which is mounted on the drive 15 with the possibility of rotation, for example through shaft. For the first hinge 17 delimbing blade 12 also equipped with features such as eyes, which is mounted on the drive 15 with the possibility of rotation, for example through shaft. The rotation axis of the hinge 16, 17 are transverse to the longitudinal direction X barrel. On figa and 2A delimbing blade 12, hinges 16, 17 and drive 15 all hosted on the same side towards the front surface 2A, preferably her front side, or in front of it, in relation to the normal direction of travel of the barrel.
In addition, because the device 1 contains the device 22 cross-cutting drive 15 does not interfere with or prevent the relocation guide rod of cross-cutting device, the device 22 cross-cutting can be placed close as possible to delimbing blades 12 to get short compact design.
The front surface 2A is usually a design that is transverse, usually essentially perpendicular to the longitudinal direction X barrel. Usually it is a flat piece that is part of a frame 2 cutting device 1. The front surface 2A can be a flat surface, or it may also contain stepped design and other Assembly members, as well as strengthening. In the examples in the drawings, the front surface 2A is both the front surface of the housing for a device, 22 cross-cutting, with the surface of which is connected delimbing blade 12.
The front surface 2A can also be tilted with respect to the longitudinal direction X, in this case, the position on fig.2b almost corresponds to the normal position, but the part that contains the surface 12b and cutting edge 12A, enshrined in the position shown in figa. Thus, C and D are not perpendicular to the longitudinal direction X, but nevertheless compact design can be achieved by placing hinges shown figa way.

Also rejected the position of the hinge 16 and drive 15 remain protected between plugs 12d 12e. Even at small rotary moving delimbing blades 12 edge 12A translates to sufficient distance Y from the trunk 13. Distance Y refers to the perpendicular distance between the cutting edge 12A and trunk 13. In the deflected position At the cutting edge 12A placed closer to the trunk 13, than the hinge 19. In the above example, which has a compact design hinge 16 placed between the hinges 19 and 17.
Cutting edge 12A placed on the opposite end of the delimbing blades 12 against the hinge 19. Cutting edge 12A has a rounded shape and concave with respect to the trunk 13. According to the example on figa and 2b delimbing blade 12 also includes surface 12b, which in a normal position And is essentially parallel to the barrel 13 and its longitudinal direction H. Delimbing blade 12 is usually a detail, made of flat details by welding, in which were also included reinforcing the walls of the design, if necessary. Plug 12d 12e are also flat parts. Between plugs 12d 12e also attached protective cover 14 with removable, to protect the actuator 15 and its compounds (see figure 3). There are two connections, with hoses preferably connected to the fluid under pressure, the drive control 15.
Drive 15 connected to the inlet line and return pipe systems for environment under pressure cutting device 1 by means of one or more distribution valves 21. The control valve 21 and its electronic control 20 are used to control the various provisions of the cylinder is used as a drive of 15. For example, the operator cutting device 1 uses the switch and electronic control 20 to select the status valves 21, and through this also to the position to which placed delimbing blade 12. In one example, the operator cutting device 1 controls the position delimbing blades 12 without automation through the above control elements.
In the deflected position At the cutting edge 12A can walk into the branch to the trunk 13. Branch strikes drive 15 and pushes delimbing blade 12 in normal position A. During the cutting of branches equipped with a blade 12 based on frame 2, it does not use the force generated by the drive 15 to leave the blade rejected the situation during cutting branches. After cutting the branches delimbing blade 12 can be left drive 15 constantly in normal position And so that the work delimbing blades 12 can be continued under normal conditions.
