Description

The invention relates to a wood processing device according to the preamble of claim 1.

A wood processing device of the type mentioned is manufactured and sold by the applicant under the name Schnitt-Griffy HS 850. This wood processing device consists of a carrying device, two gripper elements pivotably mounted on the carrying device and two actuators, each actuator having one of its ends on a respective gripper element and its other end on a common actuating element which can be moved linearly on the carrying device of a drive device arranged on the carrying device is rotatably mounted.

The invention is based on the object of improving a tree processing device of the type mentioned at the beginning. In particular, an even more maintenance-friendly and less critical tree processing device with regard to possible manufacturing tolerances should be created.

This task is achieved with a wood processing device of the type mentioned by the features listed in the characterizing part of claim 1.

According to the invention it is therefore provided that two guide elements which encompass the support device on both sides are arranged on the actuating element.

In other words, the wood processing device according to the invention is characterized by the fact that the adjusting element is no longer designed to be guided within a square tube, as in the aforementioned prior art, but that for its guidance (i.e. for guiding the adjusting element) there are only two, Guide elements running on both sides of the support device are provided. With this design, which is essentially open to the outside, the risk of jamming is significantly reduced, but above all it is easier to maintain or repair if necessary.

Other advantageous developments of the wood processing device according to the invention result from the dependent protection claims.

For the sake of completeness, reference is made to the document DE 203 12 937 U1 pointed out.

The wood processing device according to the invention, including its advantageous developments according to the dependent protection claims, is explained in more detail below using the graphic representation of a preferred exemplary embodiment.

It shows

• 1 in side view the tree processing device according to the invention;
• 2 from behind the tree processing device according to 1 ; and
• 3 from above the tree processing device according to 1 .

The wood processing device shown in the figures consists of a support device 1, two gripper elements 2 pivotally mounted on the support device 1 and two actuators 3, each actuator 3 having one of its ends 3.1 on a respective gripper element 2 and its other end 3.2 on a common, linearly displaceable on the support device 1 actuating element 4.1 of a drive device 4 arranged on the support device 1 is designed to be rotatably mounted. How out 3 As can be seen, it is preferably provided that the actuators 3 are designed in an arc shape in order to be able to realize a corresponding pivoting movement of the gripper elements 2.

Furthermore, with particular reference to 1 It is preferably provided that the drive device 4 comprises a working cylinder 4.2 operated with a fluid, in particular a hydraulic cylinder.

Furthermore, reference is also made to 1 It is preferably provided that a woody abutment 5 is arranged on the support device 1, preferably with a U-shaped section 5.1.

Like from the 1 and 3 clearly visible, it is also preferably provided that a preferably hydraulically operating cutting device 6, preferably with two scissor-like cutting knives, is arranged on the carrying device 1.

This continues with reference to 1 and also viewed overall, it is provided that the gripper elements 2 are arranged between the woody abutment 5 and the cutting device 6.

For the intended operation of the wood processing device according to the invention, an interface 7 for attachment to a boom is also preferably provided on the support device 1 of a land or water vehicle.

What is essential for the wood processing device according to the invention is that two guide elements 4.1.1 which encompass the support device 1 on both sides are arranged on the adjusting element 4.1. As explained at the beginning, the control element 4.1 is therefore easily accessible from the outside, can be easily maintained and cleaned and does not tend to tilt.

Looking a little more closely, it is also preferably provided that the carrying device 1 has a plate-shaped section 1.1 in the movement range of the adjusting element 4.1. This is preferably designed as a free, preferably rectangular surface on a side facing the drive device 4. In addition, it is preferably provided that the plate-shaped section 1.1 of the support device 1 is designed as a preferably lubricated sliding surface for the actuating element 4.1.

To improve stability, please refer to 2 Furthermore, it is preferably provided that at least one, preferably two, also plate-shaped support piece (s) 1.2 is or are arranged on a side of the plate-shaped section 1.1 of the support device 1 facing away from the drive device 4. It is further preferably provided that a main plane of the plate-shaped section 1.1 of the support device 1 and a main plane of the plate-shaped support piece 1.2 are designed to run at right angles to one another.

With regard to the adjusting element 4.1, it is particularly preferably provided that it has a plate-shaped section 4.1.2. It is furthermore particularly preferably provided that this plate-shaped section 4.1.2 of the adjusting element 4.1 is designed to project beyond the plate-shaped section 1.1 on the support device 1 on both sides. In addition, with particular reference to 2 It is preferably provided that the guide element 4.1.1 has a first guide section 4.1.1.1, 4.1.1.2 arranged laterally to the support device 1 and a second guide section 4.1.1.1, 4.1.1.2 facing away from the drive device 4. Like also good looking 2 As can be seen, it is also preferably provided that the adjusting element 4.1, in particular the plate-shaped section 4.1.2, and the two guide sections 4.1.1.1, 4.1.1.2 are designed to be screwed together. In addition, it is generally preferred that the adjusting element 4.1 is formed either from a plate and two milled castings or, among other things, from several (cost-effective) flat iron pieces.

How out 1 Particularly clearly visible, it is also preferably provided that the drive device 4, the actuating element 4.1, the actuators 3 and the gripper elements 2 are arranged one behind the other on an (imaginary) line on the carrying device 1.

The wood processing device according to the invention finally works as follows: On the one hand, the working cylinder 4.2 engages on the actuating element 4.1, which is displaceably mounted on the plate-shaped section 1.1 of the support device 1, and on the other hand, the actuators 3 engage. A stroke of the working cylinder 4.2 causes the actuating element 4.1 to be displaced on the support device and the gripper elements 2 are thereby moved. Thanks to the guide elements 4.1.1 it is ensured that the working cylinder 4.2 is guided precisely, while at the same time tilting during the lifting movement is practically impossible. In addition, the central positioning of the adjusting element 4.1 and the corresponding simultaneous movement of the gripper elements 2 ensure very good centering of the material to be cut during cutting.
