Definitions

  • the present invention relates to a wood splitting machine.
  • Austrian Patent No. AT 398.928 discloses a wood splitting machine which is essentially constituted by a footing from which a post protrudes; said post supports a vertically movable arm and a blade is associated with the end of said arm and lies above a wood block arranged at right angles to the footing; in this machine, therefore, the operator must arrange the block vertically and then actuate the lowering of tee blade, which interacts with the free end of said block, cutting along a diametrical axis of said block.
  • the grain of the wood is not always straight and therefore the block must be parted by applying considerable force to the blade, since said blade must cut the wood where the grain changes direction.
  • a blade is provided which must be placed at a diametrical axis of the cutting surface of a block which has been positioned beforehand on a support; the block must be placed so that its longitudinal axis coincides with the axis of the blade, which cuts the block after being rested on the cutting surface of said block.
  • a machine which has, proximate to the block support, two side jaws which must be actuated by the user so as to surround the block and keep it as vertical as possible, so that the user does not have to hold the block manually as the blade descends.
  • a machine which is provided with a conical point having the shape of a worm screw and protruding at right angles from a vertical frame: after placing the block on a support which is adjacent to said point, with an axis which is approximately perpendicular to the screw, said block must be moved closer to, and forced against, the worm screw, which by penetrating said wood draws it against a contrast wall of the frame. The subsequent rotation of the screw pulls the block again against said surface, thus forcing it apart.
  • the operator must apply pressure to the block to make the worm screw engage it.
  • the aim of the present invention is to solve the described technical problems, eliminating the drawbacks of the cited prior art and thus providing a machine which can split wood quickly and easily by using a modest amount of energy with respect to the prior art.
  • an object of the present invention is to provide a machine which allows to split wood in complete safety for the operator and without requiring the operator to perform particular efforts.
  • Another object of the present invention is to provide a machine which associates with the preceding characteristics that of being structurally simple.
  • Another object of the present invention is to provide a machine which has very low manufacturing and maintenance costs.
  • Another object of the present invention is to provide a machine which is reliable and safe in use.
  • a wood splitting machine which comprises a supporting base for a block or log, characterized in that it comprises a movable arm provided with a tip adapted to penetrate said block or log so as to force the parting of said block or log along the grain of the wood.
  • the reference numeral 1 designates a wood splitting machine, which is constituted by a frame 2 which is essentially composed of a post which protrudes from a footing 3 and contains mechanisms and/or devices which are suitable to actuate the axial movement of an arm 4 which can move at a suitable guide 5, which is rigidly coupled to the frame 2 by means of a suitable cross-member 6 and is arranged along the same longitudinal axis at right angles to the ground.
  • a power take-off and/or suitable sleeves and valves for feeding air or oil or other fluid, or other movement means, for example of the mechanical type, can be associated with the frame 2, for example.
  • a supporting base 7 is also rigidly coupled transversely to the frame 2 and extends below the arm 4; a block or log 8 can be placed on said base.
  • the block or log 8 is placed on the base 7 so that its longitudinal axis 9 is approximately perpendicular to the longitudinal axis of the arm 4.
  • the block or log can thus be arranged in multiple positions, such as for example those shown in Figure 1 or 3.
  • a tip 10 is arranged at the end of the arm 4 which is directed toward the block or log 8.
  • the tip is preferably frustum-shaped and is connected to the arm 4 by means of diverging surfaces 11.
  • the surfaces 11 can be arranged so as to form a surface shaped like a truncated pyramid, in which the tip 10 is associated with the vertex and protrudes axially.
  • the operation of the machine is therefore as follows. After the user has rested the block or log 8 at the base 7, the arm 4 is then actuated and descends until the tip 10 starts to bite into the block or log at its lateral surface 12, beginning to penetrate it.
  • a parting 13 begins to form approximately along a generatrix of the imaginary cylinder formed by the block or log 8.
  • the parting 13 occurs along the grain of the wood and therefore in a weaker region thereof.
  • the subsequent further extension of the arm 4 causes the surfaces 11 to affect the parting 13: in this manner, said surfaces further divaricate the block or log until they force it to split into two parts, designated by the reference numerals 14a and 14b.
  • the machine therefore does not cut the wood but merely parts it along the grain and this allows to require less force than in the described prior art, thus allowing to obtain a machine which has very low manufacturing costs.
  • Figure 5 again illustrates a wood splitting machine 1, in which the block or log 8 is rested, in the direction of the previous cut, at the base 7 so that its longitudinal axis 9 is approximately parallel to the longitudinal axis of the arm 4.
  • the block or log is smaller and therefore fits within the interspace between the base 7 and the arm 4.
  • the tip 10 thus penetrates at the cutting region 15 of the block 8, starting to part it along the grain.
  • the block 8 is then split by virtue of the presence of the diverging surfaces 11, which force two parts that constitute the block to separate along the grain.
  • the arrangement of the block or log may be any and the movable arm may be arranged along different axes and thus, for example, interact horizontally or from below or along an axis which is inclined with respect to the block or log.
