Abstract
Description
[0001] The invention relates to a wood splitting device for splitting a log into kindling.
[0002] The kindling could, for example, be the kindling described in DE 202025 103 064 U1. Application DE 20 2025 103 064 U1 is incorporated into this application, for example, with regard to possible designs of the kindling and / or a possible intended use.
[0003] Currently, kindling is painstakingly split from a log by hand, for example with an axe. However, this is very time-consuming.
[0004] It is therefore an object of the invention to create a wood splitting device which enables at least partially automatic splitting in a simple manner.
[0005] This problem is solved by a device having the features of claim 1.
[0006] According to the invention, the wood splitting device is designed and / or can be used for splitting at least or exactly one log into kindling.
[0007] The log should preferably be in chunks, free of knots and / or debarked. The length of the log can be used to determine the length of the kindling.
[0008] The wood splitting device has at least one main blade with a penetration surface and a cutting edge arranged at a, preferably lower, end region of the penetration surface.
[0009] Preferably, the penetration surface is at least substantially flat.
[0010] First, the cutting edge penetrates the log. The log is thereby separated into two parts, with one part sliding along the penetration surface and the other part remaining on the back side of the penetration surface.
[0011] Preferably, the back side of the penetration surface is at least substantially flat.
[0012] The wood splitting device has several wedge-shaped cutting edges with blades, which extend at least substantially perpendicular to the penetration surface.
[0013] Optionally, the back side of the penetration surface can also have wedge-shaped cutting edges with blades. Preferably, however, the back side of the penetration surface is free of wedge-shaped cutting edges.
[0014] For example, at least two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, or more wedge-shaped cutting edges are provided. The more wedge-shaped cutting edges are provided, the more kindling can be produced in a single splitting operation.
[0015] The wedge-shaped cutting edges can be, for example, preferably flat plates.
[0016] The number and / or position of the wedge-shaped cutting edges is preferably arbitrary. For example, the wedge-shaped cutting edges can be arranged in a V-shape (normal, sideways or upside down), a U-shape (normal, sideways or upside down), a W-shape (normal, sideways or upside down), next to each other at the same height, in a stepped, ascending and / or descending manner.
[0017] The distance between adjacent wedge edges defines the width of the kindling sticks. Preferably, the distance is always constant, so that the manufactured kindling sticks are at least substantially the same width.
[0018] Alternatively, different spacings are also possible to produce kindling sticks of varying widths.
[0019] The wedge-shaped cutting edges produce several kindling sticks with each splitting operation. This makes it possible to split a log into multiple kindling sticks in a simple, at least partially automated, way.
[0020] Preferably, the kindling sticks should be bark-free.
[0021] For example, the kindling sticks have a length between 5 cm and 25 cm, preferably between 15 cm and 20 cm, e.g. 17 cm or 18 cm.
[0022] Preferably the width and / or height of the kindling is a maximum of 2 cm, preferably a maximum of 1 cm.
[0023] For example, the width and / or height can be between 0.5 cm or 0.6 cm and 1 cm.
[0024] Due to its small width or height, the kindling can ignite quickly.
[0025] The wood splitting device automates the splitting process, at least partially. This allows for the production of large quantities of kindling in a relatively short amount of time.
[0026] Further developments of the invention can also be found in the dependent claims, the description and the accompanying drawings.
[0027] According to one embodiment, the penetration surface is at least partially designed as a deflection section or has a deflection section.
[0028] The deflection section is preferably provided on an area of the penetration surface facing away from the cutting edge, e.g., the upper area.
[0029] For example, the deflection section can protrude from a plane of the cutting edge.
[0030] The kindling sticks are deflected by the deflector section. This prevents the log splitter from becoming blocked and / or clogged.
[0031] According to another embodiment, the deflection section is concave.
[0032] For example, the deflection section can form a bulge.
[0033] The kindling sticks are deflected by the deflector section. This prevents the log splitter from becoming blocked and / or clogged.
[0034] Preferably, the main blade is straight or curved. For example, the main blade can be curved around a vertical and / or horizontal axis. The curvature can, for example, facilitate penetration into the log and / or the removal of kindling.
[0035] According to another embodiment, the cutting edge is straight, pointed or curved.
[0036] Regardless of the shape of the cutting edge, it can have a bevel. For example, the cutting edge can be beveled on both sides or on one side.
[0037] In addition to a straight cut, a wavy or serrated cut is also conceivable, for example.
[0038] Depending on the design of the cutting edge, penetration into the log can be facilitated.
[0039] According to another embodiment, the wedge-shaped cutting edges are designed to be detachable.
[0040] The wedge-shaped cutting edges can therefore be easily maintained, resharpened and / or replaced.
[0041] For example, the wedge-shaped cutting edges can be detachably attached to the penetration surface, e.g. by screws.
[0042] Alternatively, the wedge-shaped cutting edges can be permanently joined, e.g. welded.
[0043] According to another embodiment, the wedge-shaped cutting edges are arranged on detachable segments of the main knife.
[0044] The segments can, for example, be oriented parallel to each other.
[0045] Preferably, the segments have a width between 0.3 cm and 5 cm, preferably between 0.5 cm and 2 cm, e.g. 1.1 cm.
[0046] The segments, including the wedge-shaped cutting edges arranged on them, can be easily maintained, resharpened and / or replaced.
[0047] Preferably, the wood splitting device, e.g. the main knife, can have a segment holder for the segments.
[0048] The segment holder can, for example, have a guide, preferably a cam guide. For instance, the segment holder can form a groove into which the segments can be inserted.
[0049] A fixing device can secure the segments in the inserted position. For example, end caps can prevent unintentional detachment from the segment holder.
[0050] The fixing device can be, for example, a hook-in, clamp, clip, plug-in, snap-in, magnetic, pin, and / or screw-in device. Fastening can preferably be done without tools.
[0051] For example, at least one threaded screw can be provided for clamping.
[0052] In another embodiment, the wedge edges are straight, oblique or curved.
[0053] For example, the wedge edges can be oriented parallel to each other.
[0054] If the wedge-shaped cutting edges are angled or curved, the kindling can be deflected outwards, for example. This prevents the log splitter from becoming blocked and / or clogged.
[0055] According to another embodiment, the blades are straight, pointed or curved.
[0056] Regardless of the blade shape, they can have a grind. For example, the blades can be ground on one or both sides.
[0057] In addition to a straight cut, a wavy or serrated cut is also conceivable, for example.
[0058] Depending on the design of the blade, penetration into the log can be made easier.
[0059] According to another embodiment, a fastening device is provided for vertical, horizontal or inclined fastening of the main blade.
[0060] The mounting device allows attachment to a lifting device, such as a workshop press, a toggle press, a mandrel press, and / or a log splitter. The lifting device can be operated manually, mechanically, hydraulically, pneumatically, and / or electrically.
[0061] For example, the lifting device can be a component of the wood splitting device.
[0062] The fastening device essentially forms an adapter for attachment to the lifting device.
[0063] The lifting movement can be performed in a vertical or horizontal direction, or in an intermediate position.
[0064] If the main blade is oriented horizontally or at an angle, the kindling can fall downwards due to gravity. This prevents the log splitter from becoming blocked or clogged.
[0065] According to another embodiment, several main blades are arranged on the mounting device.
[0066] For example, at least or exactly two, three, four, five, six or more main blades are arranged on the mounting device.
[0067] During the splitting process, the main blades move together. This allows a large number of kindling sticks to be produced in a single splitting operation.
[0068] Preferably, the main blades are oriented parallel to each other.
[0069] Preferably, the main blades are arranged offset from each other. For example, the main blades have a height difference. In this way, the main blades penetrate the log one after the other, thus reducing the required force.
[0070] All aspects, embodiments, and features of the invention described herein can be combined with one another, preferably also independently of the specific embodiment in which they are mentioned. Preferably, all subject matter of the dependent claims can be combined with each other and with the subject matter of the independent claim.
[0071] It is generally noted that terms like "ein" (a) and "eine" (a / an) do not necessarily mean "exactly one" or "exactly one," although this is also possible. The terms "ein" and "eine" can therefore be understood as "at least one" or "exactly one." The use of the singular preferably includes the possibility of the components being plural, and vice versa.
[0072] It is noted that "vorzugsweise" and "bevorzugt" can be translated as "preferably" in English. A feature introduced by "vorzugsweise" or "bevorzugt" is purely optional, can be omitted, and does not constitute a limitation, for example, of claims.
[0073] The invention is described below by way of example with reference to the drawings. The drawings show: Fig. 1 a perspective view of an embodiment of a wood splitting device according to the invention, Fig. 2 to 6 schematic front views of different embodiments of a wood splitting device according to the invention, Fig. 7 a perspective view of another embodiment of a wood splitting device according to the invention, Fig. 8 a perspective view of a further embodiment of a wood splitting device according to the invention, and Fig. 9 and Fig. 10 side views of various embodiments of wood splitting devices according to the invention.
[0074] It should first be noted that the embodiments shown are purely exemplary. Individual features can be implemented not only in the combination shown, but also individually or in other technically feasible combinations. For example, the features of one embodiment can be combined with features of another embodiment in any way. The number, shape, and / or position of the wedge-shaped cutting edges are, in principle, arbitrary.
[0075] If a figure contains a reference numeral that is not explained in the immediately associated descriptive text, reference is made to the corresponding preceding or subsequent explanations in the figure description. Thus, the same reference numerals are used for identical or comparable components in the figures and are not explained again.
[0076] Fig. Figure 1 shows a wood splitting device for splitting a log into kindling.
[0077] A fastening device 8 is provided for attachment to a lifting device (not shown).
[0078] A main blade 10 has a penetration surface 12.
[0079] In the illustrated embodiment, the penetration surface 12 is flat. Alternatively, it can be curved, for example.
[0080] A cutting edge 14 is arranged at the lower end of the penetration surface 12.
[0081] In the embodiment shown, this is straight. Alternatively, it can be, for example, pointed or curved.
[0082] The cutting edge 14, for example, is ground on both sides.
[0083] In addition to the straight cut shown, a wavy or serrated cut is also conceivable, for example.
[0084] Several wedge-shaped cutting edges 16 with blades 18 are provided, which extend at least substantially perpendicular to the penetration surface 12.
[0085] The wedge-shaped cutting edges 16, for example, are arranged in a V-shape (upside down, in this case with the point facing upwards). This facilitates penetration into the log.
[0086] In the embodiment shown, the blades 18 are straight. Alternatively, they can be, for example, pointed or curved.
[0087] The blades, for example, are ground on both sides.
[0088] In addition to the straight cut shown, a wavy or serrated cut is also conceivable, for example.
[0089] The wedge-shaped cutting edges 16 can, as in Fig. 2 is shown, parallel to each other, and aligned straight. (The blades 18 are not shown in the schematic diagram.)
[0090] However, it is also conceivable that the wedge-shaped cutting edges 16 are arranged obliquely, as in Fig. 3 is indicated. For example, the inclination can be between 1° and 20°, e.g. 2°, 3°, 4° or 5°.
[0091] As in Fig. As shown in Figure 4, the wedge-shaped cutting edges 16 can form a normal V-shape (in this case, point downwards).
[0092] A descending order, as in Fig. As shown in 5, an ascending arrangement is just as conceivable.
[0093] Furthermore, as in Fig. As shown in Figure 6, several, e.g., two, descending rows of wedge-shaped cutting edges can be arranged side by side. Three, four, five, or more rows are also conceivable.
[0094] Preferably, the wedge-shaped cutting edges 16 are removable. This allows the blades 18 to be easily resharpened.
[0095] How Fig. As shown in Figure 7, the main knife 10 can have several segments 20. Each segment 20 can, for example, have at least one wedge-shaped cutting edge 16.
[0096] The main knife 10 can have a segment holder 22 designed as a guide for the segments 20.
[0097] The segments 20 can be inserted into the segment holder 22.
[0098] A fixing device (not shown), e.g. an end cap, can fix the segments 20 in the inserted position.
[0099] For example, at least one threaded screw (not shown) may be provided for clamping.
[0100] In Fig. Finally, there are several, e.g. three, main knives 10 arranged on the fastening device 8.
[0101] The main knives 10 can be offset from each other in height, so that they successively penetrate the log.
[0102] In Fig. 9 and Fig. Figure 10 shows side views of various main knives 10, with the wedge-shaped cutting edges 16 omitted for better visibility.
[0103] The back sides of the penetration surfaces 12 can be inclined or straight.
[0104] In Fig. 9 A deflection section 24 is provided in the upper area of the penetration surface 12. This deflects the kindling sticks.
[0105] In Fig. 10, however, forms a region of the penetration surface 12 itself as a deflection section 24. This is concavely curved.
[0106] The deflection section 24 prevents the wood splitting device from becoming blocked and / or clogged.
