Description

The invention relates to a firewood splitter for inserted into a tub of firewood with the features of the preamble of claim 1.

Log splitter of this type for producing fissured wood in dimensions, which is intended for use in household furnaces are provided with a gap in which the cut wood is introduced and pressed with a punch through the blades of a fixed cutting and discharged the slit with a conveyor.

If in a splitting process the piece of wood only partially split to limit the cost of the cutting and the provision of the necessary splitting force, the non-crushed part of the piece of wood is stored during the splitting process on a separate tray, is with a separate device from there again brought into the starting position and the split wood must be ejected from the cutting unit. The cost of building log splitter is increased, as well as the overall length increases accordingly.

A wood splitter for fissure wood for household furnaces should split evenly with the lowest possible splitting force, eject the split wood reliably, have a compact design and be easy to use and less susceptible to malfunction.

This object is achieved in a firewood splitter according to the preamble of claim 1 with the features of the characterizing part of the claim.

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

An inventive firewood splitter is provided in a known manner with an insert tray for the piece of wood, with a centrally recessed bottom, the recess most conveniently has a flat V-shaped form.

The insert tray is closed at the rear, which faces away from the cutter, with a support wall, which is fixedly mounted together with the insert tray.

An opposing cutter, the cutting knife has a running on the course of the soil shape and thus results in a uniformly large separation distance, the height lying above the ground, is provided with downwardly welded splitting blades, the cutting edges against the cutting edge of the cutting blade running reset , whereby the splitting process requires less force and is introduced more uniformly.

The cutting unit is movable against the piece of wood with the splitting force of hydraulic power cylinders, which is initiated after closing the cover.

The cutting knife has a blade with a surface which forms a support for the non-separated part of the piece of wood during the splitting process, in the gap position.

In rest position, the blade lies substantially behind a scraper wall, while the non-split part of the piece of wood stripped again comes to rest on the bottom of the insert tray. It is thus the compact design of the machine possible and the mechanical means for crushing are limited to a simple and less prone to failure construction.

Below the cutting unit, a discharge conveyor for the split wood is arranged, which is laterally provided with guide surfaces for the chipped wood pieces.

Thus, the return of the non-split part of the piece of wood easier and can be done faster, the insert tray with the support wall and the cutting unit with the Abstreifwand at an angle of about 10 to 30 degrees and very low of 15 degrees, against the horizontal to Einlegewanne down inclined.

For uniform, safe displacement of the cutting mechanism under the considerable splitting force, this is displaceably guided in the region of the separating knife on both sides in guide rails which are open to the side walls of the insert tray.

So that the space is covered laterally next to the cutting mechanism against the ingress of chipped wood parts, guide plates are mounted on both sides of the cutting mechanism, which slide when splitting behind the side walls of the insert tray.

The downwardly directed splitting blades are welded to the blades, especially in the splitting direction, at approximately the right angle to the blade of the separating blade.

Downwards and backwards, the blades of the splitting blades end freely and are arranged essentially parallel to one another, whereby the pushing through and out of the splitting wood can take place largely stagnation-free and energy-saving.

By covering the blades of the splitting blade down to a cover plate, which is mechanically connected to the cutting mechanism, the leadership of the split piece of wood during the splitting process in split position is present and secured the delivery from the cutting unit to the discharge conveyor.

For the necessary entrainment, the cover plate is attached to both sides of the downwardly guided brackets and stored to avoid interference from the accumulation of fissile wood on compression springs movable down.

The cutting knife of the cutting mechanism enters with the cutting edge at the end of the gap position in a matched gap in the support wall of the insert tray ( 1 ), as well as the cover plate in a gap under the retaining wall at the bottom of the insert tray, whereby a complete and clean separation of the piece of wood is ensured.

The production of the splitting force for the cutting unit takes place uniformly with hydraulic cylinders arranged on both sides, which are fed by a hydraulic pump arranged in the machine.
