wood splitter

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

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

Log splitters for log splitting are provided with fixed splitting knives or cutting frames against which the wood is pushed and split by a hydraulically driven pusher to be slid behind it on an unloading table.

The machine length thereby increases by the length of the delivery table; with multi-bladed knives, the required splitting force increases and the operating device is mostly on the side of the machine, increasing the operator's path.

The object of the invention is to increase the splitting performance in a log splitter wood trimmings and if wished to keep the maximum splitting power lower, even Spaltfähigkeit of strains diameter given.Weiters is the way for the operator if possible to keep short and the machine at work on to leave attached trailer towed.

This object is achieved in a log 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, like claim 1, at the same time form part of the description of the invention.

A log splitter according to the present invention is provided in a known manner with an actuator for loading and unloading and log splitting, and with at least one horizontal timber loading basket hinged to a flat bed table and a splitting blade, as well as a hydraulic cylinder driven by a push rod driven by its piston rod and displaceable over the length of the bed table is.

The conclusion of the support table on both sides with fixed counter plates, at right angles to this completed, to accommodate the nip pressure, allows to perform the splitting operation in both directions. For the passage of the splitting blade, which is behind the counter plates, so that the support table before and before a splitting operation, for the purpose of setting up the parent wood without hindrance, this and the counter-plates are each provided with a gap.

The splitting knife is equipped with a cutting edge for each direction of movement and therefore gap direction. It is attached to the piston rod of a hydraulic cylinder which is guided below the support table.

On both sides of the support table in each case a Belade¬ is hinged, which is parallel to the direction of movement of the Spaltmessers with a hydraulic cylinder can be pivoted up and has a lowered position on the ground loading surface. After the splitting process, the split wood with the other loading basket is transported to the ground and there removed from the Lade¬fläche, so that the loading area of the first loading ¬korbes is kept free for further loading. The lateral arrangement of the loading baskets allows a shorter path for the operator and thereby a rapid and fatigue-free processing.

The hydraulic cylinder of the splitting blade and the hydraulic cylinders of the loading baskets are supplied by a hydraulic pump which is driven by a PTO connection or by a combustion or electric motor.

The actuating device is arranged at the longitudinal end of the Holz¬spalters, which is closer to the storage table, whereby the way to both sides of this very short and the clarity is very good. For the control of the operations, two control levers for two-hand operation are arranged on the actuating device, each having two separate switching stages for the two directions of movement of the splitting blade. For the switching of the two loading baskets, two further switching levers are mounted. The shifters control the hydraulic flow to and from the hydraulic cylinders directly or via electrohydraulic interference.

The wood splitter is constructed on a traveling frame provided with a trailer tongue which is located at the same longitudinal end as the PTO connection and the hydraulic pump are mounted and the actuator is arranged at the other longitudinal end of the log splitter.

An embodiment of the invention is described below.

It shows:

Figure 1 is a wood splitter in side view, schematically.

Fig. 2 shows the wood splitter of Figure 1, in plan view, schematically.

Fig. 3 shows the wood splitter of Figure 1, seen from the drawbar side, schematically.

Fig. 4 the log splitter in an oblique view, viewed from the side of the actuator, the opposite loading basket raised, schematically.

In Fig. 1, the structure of the wood splitter on a travel frame 18 can be seen, at one longitudinal end 16 of which an actuating device 15 for a splitting blade 2 and two blade driers 7 is arranged.

At the other longitudinal end 20, there is attached a trailer hitch 19, and under the traveling frame 18, there is disposed a PTO connection 14 for operation with a tractor, and a hydraulic pump for feeding the hydraulic cylinder 3 for the splitting blade 2 and the hydraulic cylinders 11 for the loading baskets 7.

On the traveling frame 18, a support table 1 is arranged, on both sides of perpendicularly fixed counterpart plate 5 and 5 '.

The visible loading basket 7 is lowered to the ground on which it can rest with a part designed as a loading area 12.

From above, the arrangement is also apparent in Fig. 2, wherein the support table 1 with both sides of the traveling frame 18 each consist of an inner and an outer surface part and the two on the sides 10 in the longitudinal direction corresponding to the movement directions 8 and 8 'of the splitting blade 2, hinged loading baskets 7, one of which was lowered.

Likewise, the gap 6 which divides the support table 1 in the longitudinal direction and the splitting blade 2 displaceable therein are shown and the gaps in the counter-plate 5, 5 'behind the splitting blade 2 is movable to the support table 1 for loading and unloading of the wood freely do.

In the view of the wood splitters from the side of the operating device 15 in which the two control levers 17 are visible for two-hand operation, the loading baskets 7 hinged on the sides of the support table 1 on both sides are shown in a lowered position in which the loading and unloading can take place.

Likewise, the arrangement of the hydraulic cylinders 11 for the swinging of the loading baskets is reproduced.

In Fig. 4 an overview of the arrangement of the wood splitter is made in the all described components are shown and through which the view of the gap blade 2 in the gap 6 of the support table 1 is visible that is possible by both sides mounted blades 9 splitting of the wood in both directions of movement.

In this illustration, a loading basket 7 is partially lifted and the other loading basket 7 with the loading area 12 lowered to the ground.
