Separation device for standing wood such as bushes

The invention relates to a separating device for standing Wood goods like bushes, with a movable frame for at least one felling or pulling tool for the subsequent cutting of the wood.

Such separating devices for standing wood as it grows distributed on the site, in which the wood cut into pieces are known in various ways: cutting cylinders, saw chains, cutting discs, etc. These devices attack the wood such as trees, bushes, sugar cane, etc. and cut the rhizomes away.

As the attack width of the felling or attack tools is comparatively limited, it is very difficult to do that

2546U1

terrain that can be deforested by this tool alone, Poles, twigs and other plant materials captured by the attack and feed tool should be fully cleared. ·

With the disconnection device according to the invention, all Plant growth in the working path of the felling or feeding tool captured, bundled and thus fed as a whole to the felling or attack tool.

This is indicated by the characterizing features of the claim achieved. Claims 2 and 3 have advantageous developments the separating device according to the invention to the content.

Further details, features and advantages of the invention emerge from the following description of an embodiment. management example based on the drawing.

It shows

Fig. 1 is a greatly simplified schematic representation of a central section in side view of an inventive Cut-off device and

FIG. 2 is a view from the direction of the arrows II-II in FIG.

The device shown in the drawing has a frame 1, which is designed as a tooth cylinder AbhoIzwerkzeug 2 and one also as a tooth cylinder trained cutting or cutting tool 3 is provided, which is rotatably mounted and rotatably driven by a motor are. The cutting cylinder and the chipping cylinder have a common tangent, so that that of their rhizomes or the like. Plants separated by the felling cylinder 2 are conveyed to the cutting or chipping cylinder 3, which picks them up and ejects them automatically.

2546U1

According to the teaching of the present invention, all plants lying in the area of the felling cylinder 2 are to be covered and collected or bundled in such a way that they are inevitably separated without exception. -

A special collection device is provided for this purpose. This has two arms 4 and 5 that are rotatable are each mounted at one end on the sides of the frame 1 on the rear and outside of the logging cylinder 2. In the illustrated embodiment, the arms are connected to pivot pins 6 and 7 (see. Fig. 2) each in a bearing Ö and are each connected to a hydraulic drive (Fig. 1).

As FIG. 1 clearly illustrates, the arms 4 and 5 extend above the logging cylinder 2 into one another and planes parallel to the axis of the logging cylinder and substantially in the direction of the axis of the cutting or Cutting cylinder 1 lie, the ends 10 are also and 11 of the arms (see FIG. 2) bent backwards.

As the cutting device moves forward, the two working cylinders 2 and 3 _f turn to cut a new path in the plant material. The arms 4 and 5 are open in the manner shown in FIG. 2 with dashed lines. In this open position, the ends 10 and 11 penetrate the vegetation at points axially outside the felling cylinder 2, that is, they cover a greater width of the timber than the working width of the felling cylinder 2.

Then the arms 4 and 5 are simultaneously with the cutting of the felling cylinder 2 in the wood for severing at the level of the rhizomes actuated by the hydraulic cylinder 9 and in the direction of the solid lines

2546U1

in Fig. 2 illustrated closed position moved. During this pivoting movement, the arms 4 and 5 collect the plant matter and present it to the felling cylinder or cutting device, which cuts it off above the root stocks. The plant matter remains in the grip of the arms until it is safely inserted between the two cylinders is, so that the cutting or cutting cylinder 3 are fully effective and can cut the material. That I the two arms 4 and 5 cover and their ends 10 and 11 are bent backwards, the plant material is securely gripped from the moment that the Sanunel movement begins. No material can escape laterally, so that it is ensured that on the one hand all of them are in the working path existing vegetation is separated by the felling cylinder 2 and on the other hand the entire vegetation in the working gap between the logging cylinder 2 and the chipping cylinder 3 is drawn in and processed.

Instead of a synchronous and symmetrical pivoting movement of the arms 4 and 5, the arms can also be independent of one another can be controlled in order to optimally adapt the collecting movement to the nature of the respective plant population.

In addition, several pairs of arms can of course also be arranged one above the other and in synchronous movements or follow-up movements can be controlled.

As the above description shows, the invention is not limited to the illustrated embodiment; on the contrary, numerous modifications and changes are possible without departing from the scope of the invention. The inventive Separation device can be used for cutting down very different types of vegetation and is suitable especially for trees, shrubs and bushes.

Claims (3)

2546U1 - 5 patent (protection) claims: fly separating device for standing wood such as bushes, with a movable frame for at least one Abholzbzw. Insertion tool for the subsequent cutting or machining of the goods, characterized by a collecting device with at least two on the sides of the frame (1) in the vicinity of the felling tool (2) pivotally supported arms (4, 5) which are arranged in two superimposed Levels extend above the logging tool and are connected to actuating devices (9), wherein the arms are arranged in such a way that, in their extreme open position, they provide access to the felling tool fully release and overlap in their fully closed position so that one arm is over the other lies. 2. Separating device according to claim 1, characterized in that the ends (1O, 11) of the arms (4, 5) are bent backwards are, so that in the closed position or during the closing movement they oppose a lateral sliding out of the wood and in the open position can penetrate the plant matter from the outside without interference. 3. Separating device according to claim 1 or 2, characterized in that that the actuating device (9) for each arm (4, 5) is a preferably hydraulic pivot or Is a rotary or rotary motor that sits on the pivot shaft or pivot pin (6, 7) of the respective arm. 60981 7/0421 Blank page
