Description

The invention relates to a log splitter for horizontally splitting trunk wood with the features of the preamble of claim 1.

Wood splitters are used in forestry and agriculture to use either an internal combustion engine, such as a tractor or an electric motor depending on availability.

Wood splitters for horizontal log splitting are equipped with fixed splitting knives or cutting frames against which the wood is pushed and split by a hydraulically operated pusher to be pushed onto a storage table behind it. The machine length is thereby increased by the length of the tray table; with multi-bladed knives increases the required splitting force and the actuator is usually located laterally on the machine, whereby the way for the operator is increased. The log splitter of the parent log DE 10 2013 018 122.4 , EAZ: BINP22DE1, is provided with a substantially flat support table with a central longitudinal gap for the splitting knife.

When storing logs, its arrangement in the appropriate gap area of the web of the splitting blade is not always ensured.

The object of the invention is in this log splitter, the centering of the position of the horizontal logs in a simple manner and quickly.

This object is achieved with a wood splitter of the type mentioned, with the features of the characterizing part of claim 1.

The subclaims relate to particularly advantageous embodiments of the invention and, as well as claim 1, at the same time form part of the description of the invention.

In a wood splitter with an actuator for loading and unloading and log splitting and with at least one hydraulically operated loading basket for horizontal timber, gap in the longitudinal direction in which a splitting blade of a hydraulic cylinder over the length of a flat support table is movable, on both sides with counter plates is completed, there is a suitable solution in the occurring alternating layers and loads by processed logs in each case on either side of the gap one surface of a Holzzentriervorrichtung parallel to this from the plane of the support table in a raised holding position, inclined obliquely upward from the gap away to pivot. Thus, a log lying on the support table can be slid over the gap in the middle and treated centered in this position.

In this particularly suitable and preferred embodiment, in which the Holzzentriervorrichtung is formed with flat surfaces, these cover at rest recesses on both sides of the support table, whereby the flat surface thereof is maintained throughout.

In order to pivot the surfaces of the Holzzentriervorrichtung in an obliquely upward and outward centering, are arranged on each side of the support table below this, at a distance from the gap for the splitting blade, pivot axes at which these surfaces are pivotally mounted upward.

The surfaces of the Holzzentriervorrichtung extend on both sides of the gap for the splitting blade substantially over the distance between the counter plates and the width on each side of the support table, on both sides of the gap, at least up to the half.

As a result, even obliquely or laterally lying logs are detected evenly and moved centering and the angle of attack can be chosen flat.

It is therefore an oblique employment of the surfaces depending on the design of the support table and the fissile material on both sides of the gap with about 30 to 45 degrees sufficient.

At the same time an oblique shortening of the edges of these surfaces with about 30 to 45 degrees, with parallel to the sloping side edges of the support table by avoiding steeper extending outer edges for the stress of the surfaces overall low.

In order to avoid the ingress of fissile material or gap drop under the surfaces of the Holzzentriervorrichtung it is advantageous to install on both sides of the outer edges with downwardly directed covers that keep the openings in the support table at all positions of the Holzzentriervorrichtung always closed.

For the quick and easy operation of the Holzzentriervorrichtung hydraulic cylinders are arranged on both sides of the support table below, which are switched by a control station, with which the surfaces of the Holzzentriervorrichtung be raised.

An embodiment of the invention for supplementing the wood splitter is described below. Show it:

1 a log splitter with the two raised surfaces of the Holzentriervorrichtung in plan view, schematically;

2 after the log splitter 1 in a side view with a raised surface facing the view of the Holzzentriervorrichtung, schematically;

3 after the log splitter 1 in rear elevation with raised surfaces of the Holzzentriervorrichtung, schematically;

4 after the log splitter 2 , in cross-section through the support table, cut in front of the surfaces of the Holzzentriervorrichtung, schematically.

On a driving frame 18 The structure of the wood splitter is installed according to the parent application, with a flat, horizontally arranged support table 1 on both sides of perpendicularly mounted counter plates 5 . 5 ' is limited and the center with a gap 6 . 6 ' for a powered splitting knife 3 is provided, which is in the counter plates 5 . 5 ' continues. In width is the support table 1 with sloping edges converging on both sides to a length sufficient for logs of the usual length of 1 to 1.5 meters.

At the outer longitudinal edges are on both sides 10 . 10 ' of the support table 1 loading baskets 7 hinged with horizontal swivel axles, can be swung up from the ground, with which the load is carried out with logs.

On the two sides 10 . 10 ' of the support table 1 are surfaces 4 . 4 ' a wood centering device 3 arranged horizontally to the gap 6 and are arranged pivotably parallel to this, which are shown in the swung-up on both sides outwardly to the centering position.

The surfaces 4 . 4 ' cover recesses at rest 11 . 11 ' In the areas 10 . 10 ' of the support table 1 from. The lateral outer edges 13 . 13 ' the surfaces 4 . 4 ' are converging outwardly at an angle of approximately 30 to 45 degrees, ie substantially parallel to the inclined edges of the support table 1 arranged and the outer outer edges 14 the surfaces 4 . 4 ' that are more than half the width of the support table 1 occupy, parallel to its outer longitudinal edges.

The lateral outer edges 13 . 13 ' the surfaces 4 . 4 ' are with covers 16 . 16 ' and the outer edges 14 are with covers 17 provided, which reach down and the recesses 11 . 11 ' in all swivel positions of the surfaces 4 . 4 ' keep closed; These are, as indicated, folded several times.

At the driving frame 18 is at one end a trailer ditch 19 and at the other end an actuator 15 for the splitting knife 2 , the loading baskets 7 and the wood centering device 3 appropriate. In the middle area of the driving frame 18 is a support frame 20 arranged for stable installation during the splitting process.

2 shows beside features 1 a horizontal view of the facing surface 4 the wood centering device 3 in raised position 9 ,

In the rear view of the log splitter in 3 are the two surfaces 4 . 4 ' shown laterally and in the swung centering position, as well as the two Hydraullikzylinder 8th . 8th' reproduced for their activity. Other names correspond to those of 1 and 2 ,

The section in rear view of the log splitter in 4 also shows the pivot axes 12 . 12 ' the surfaces 4 . 4 ' the wood centering device 3 and the dipping of the covers 16 . 16 ' the surfaces 4 . 4 ' in recesses 11 . 11 ' of the support table 1 , Still the gap 6 ' in the counter-plate 5 and the splitting knife 2 ,
