SYKE HARVESTER OR PROCESSOR

The present invention relates to a heart rate harvester or processor according to the preamble of claim 1.

Currently, heart rate-type harvesters and processors generally have two longitudinally movable frames. One frame has 10 typically pruning members (pruning blades) and the other has a tree holding member (pinching jaws for pulling or holding the tree).

Typically, the clamping jaws are opened inside the split pulse during the movement. In this case, the tree is only supported and held in place by means of pruning-15 knives. The blades must be quite sliding along the wood to achieve a good pruning result.

The downside of the current device is that the wood remains in the grapple when the jaws are opened. The tree can descend to measure the length-20 of the five bodies. Particularly on slopes, there may be skidding of the harvester, ·,; This causes the feed to slow down or stop.

• · · • • •, ·. ; It is an object of the present invention to provide a heart rate harvester or processor, · · · • ·, ···. which prevents the tree from slipping. In addition, the goal is that the same heart rate • • • · · 25 harvester or processor can effectively handle • · · · ·. ···. highly variable trees. The goal is still to have exact lengths of ♦ ··· trees.

• · • · · · · ·

The above disadvantages can be eliminated and the above objectives will be achieved. 30, characterized by what is defined in the characterizing part of claim 1. Preferred embodiments of the invention are the subject of the dependent claims.

The main advantage of the invention is that the wood of the heart rate harvester or processor 2 is prevented from slipping by means of the inventive gripping means or jaws. which prevents the measuring roller from rotating freely or the wood from moving so that the measuring roller does not rotate. Another advantage is that the same heart rate harvester or processor can efficiently handle large diameter trees because the inside of the holding member has a different curvature than the crate-10 knife. The invention also has the advantage of accurately measuring lengths in difficult harvest conditions such as hillside or the like. In the invention, further wood-holding members (jaws) are inserted into the frame where the pruning blades are. The invented additional jaws are closed to support the wood before the actual press jaws in the movable frame are opened. The additional jaws discovered during the out-15 movement of the heart rate, in turn, are opened to allow the wood to slip normally through the pruning blades, pulled by the clamping jaws in the movable body. The holding means provide a firm grip on the tree when the actual press jaws need to be opened to move them to a new position. The length measurement of the wood becomes more accurate when the trunk is better retained at the grapple-20. The supply of wood becomes more efficient, especially when the wood has to be pulled. I up this hill. The tree cannot slide back in the grapple • •. during the weather haul. Obviously, the invented heart rate harvester or processor • · t. ' : Great financial savings in logging.

The figure further shows the known body 2 of the heart rate harvester, a cutting device 2a having a chain saw 2aa. The body 2 also has known wood-holding members 2b, i.e. clamping jaws. The figure also shows a known support frame 15 4 which is connected to the boom of a rotating machine via a rotator.

In Figures 1 and 2, a support frame 4 is attached to the frame 1, the frame 1 serving as a lifting point for the wood, whereby the reciprocating frame 2 is freely movable when approaching the frame 1 without the strain 20 on the tree.

It has now been found that at least one holding member 3 has a holding surface 3a on the wood. to prevent slipping. The holding surface 3a is on the wood side of the holding member 3, i.e. the so-called.

• · «*. 30 inside. Figure 3 shows that the opposing retaining members 3 are of the same structure.

It is also invented that the gripping surface 3a consists of roughening and / or separate elevations. Figures 1, 2, 3, 4 and 5 show that at least one of the retaining means 3 has one or more transverse timber retainers 4 3aa. It is also inventive that at least one of the retaining surfaces 3a is formed by roughings transverse to the wood, whereby the wood 5 is held in place effectively, even with a slight clamping force. The advantage of using a small clamping force is a small damage to the wood surface. In some cases of harvesting, it is desired to keep the wood surface as intact as possible.

Figures 1, 2, 4 and 5 show that, viewed from the end direction of the wood, at least one of the holding means 3 is partially shaped as a wood-side profile of the pruning blade. That is, the plane of the pruning blade and the contact surface of the holding member 3 with the wood are similar, at least in part.

Contrary to the figure, according to an inventive solution, at least one of the retaining means 3 is shaped differently from the pruning blade when viewed from the end of the wood. That is, the geometry of the shape corresponding to the tree of the holding member 3 is different from the broad geometry of the pruning blades, whereby large and small diameter trees can be processed by the same heart rate harvester.

Figures 1, 2, 4 and 5 show an inventive version of the retaining member 3, •; wherein the holding member 3 is provided with at least one removable or fixed • · ·; * ·, · cutting surface for pruning and / or barking. In Figure 4, the second • «; ***; the holding member 3 is provided with a cutting surface 3b which is secured with fastening screws 3ba to the body of the holding member 3.

Fig. 5 shows a holding member 3 having a movable cutting surface 3c, pivotally attached by a joint 3ca to the body of the holding member 3, further moving; the motion of the cube surface 3c is influenced by the transfer member 3cb. The transfer member 3cb is · 1 · 30 at one end of the movable cutting surface 3c and at the other end · · · ·. ···. attached to the body of the holding member. In the figure, the § transferring member 3cb is a compression spring which presses the movable / pivoting cutting surface 3c towards the tree, whereby the moving cutting surface 3c closely follows the shape of the wood and thus improves pruning. 35 1 results. Inventively, the holding member 3 is movably articulated with one or more pruning blades 5 which can extend the wide geometry of the actual pruning blades, thereby improving the result of pruning and / or debarking the wood.

Contrary to the figure, it is also found that the holding member 3 is at least partially shaped as a wood holding member 2b.

Operation of heart rate harvester. As the body 2 starts to move, the so-called. out, that is, at a distance of 10 from the body 1, which movement is called pulse outward movement. Prior to the start of the ejection, the holding members 3 are opened to allow the wood to move in the longitudinal direction, the wood holding members 2b being pulled, the tree being pruned as it slides through the pruning blade of the frame 1. The return movement is called the return of the frame 2 back to the closest position to the frame 1. Before the return movement begins, the holding member-15 met 3, or additional jaws, are closed to support the wood before the actual wood-holding members 2b are opened. By means of the holding means 3, the wood is held firmly in the grab without moving longitudinally against the length measuring member 5 when the wood holding members 2b are open and thus do not support the wood. Thanks to the holding members 3, in addition to increasing the accuracy of the length measurement, the feed of the wood 20 becomes more efficient, especially in conditions where the wood has to be pulled uphill, because the wood cannot slip in the grapple. .1. back into the heart rate during exercise.
