Definitions

  • Patent databases contain no solutions, which address sliding plates for vertical log splitters.
  • Commercially available log splitters produced by the company Lancman have axes welded to plates, which slide along the vertical pillar of the splitter.
  • Commercially available log splitters of companies Uniforest and Krpan do not solve the problem of lubrication of sliding plates.
  • US patent application number US 2014/0124097 A describes a log splitter comprising guides installed in a supporting frame, wherein a carrier plate with an axe comprising peeling plates on both sides moves along the said guides.
  • the peeling plates enable simultaneous removal of the tree bark and splitting. This solution does not allow lubrication of the carrier plate as is the case in the present invention.
  • the sliding plates according to the invention may be produced in different manners.
  • 0.5 to 80 % (w/w) of graphite may be added to the base material during manufacture of plates.
  • Graphite may also be added to already manufactured plates in a form of inserts, wherein the inserts represent 0.5 to 80 %(w/w) of the material.
  • a third option is to add a thin layer of graphite to one surface of the plate, wherein the amount of graphite is between 0.5 and 80 % (w/w).
  • the thin layer of graphite on the plate is prepared by pouring the material in a suitable mould.
  • Graphene is a solid material composed of pure carbon, where the atoms are distributed in the form of regular hexagons similar to graphite, but with a thickness of one atom, and can be used instead of graphite, preferably in the form of a thin layer on sliding plates.
  • the essence of the log splitter with improved sliding plates is in that a first pair of sliding plates is in a direct contact with the base plate for carrying the axe, the base plate moving along the guide, wherein the sides of the guide move along two parallel distancing elements and a second pair of sliding plates.
  • the sliding plates and said distancing elements together with mounting plates are fixed with screws, which are inserted into holes prepared in said elements.
  • the number of holes is arbitrary, preferably there are five.
  • a pair of thin distancing elements may be provided between the distancing elements and the second pair of sliding plates, in order to reduce airiness between sliding plates and sliding guide, which is created due to use of the log splitter.
  • Said thin distancing elements may also be provided between the first pair of the sliding plates and the distancing element, but their removal is more complicated, hence the embodiment where thin distancing elements are provided between the second pair and the distancing element is preferred.
  • the log splitter with improved sliding plates, the base plate or the guide according to the invention is a machine, which may be driven via a PTO shaft of a tractor or with an electromotor.
  • the log splitter may be designed as a vertical or horizontal machine for splitting logs.
  • a possible embodiment of the invention is a vertical log splitter having a frame 1, wherein in the upper part of the frame 1 a cylinder 2 with a piston 21 is mounted.
  • the piston 21 is installed in a cylindrical attachment 31 welded to an axe 3.
  • the inner side of the axe 3 is welded to an axe carrier (also called base) plate 4, which is parallel to an essentially straight guide 1b'of a vertical pillar 1b of the frame 1.
  • the vertical log splitter has on its bottom part of the frame 1 a base 1a, on which the vertical pillar 1b stands.
  • the upper part of the pillar 1b is surrounded with carrier sides 1c and 1c' of a plate 1d, through which the cylinder 2 with the piston 21 is installed.
  • the guide 1b' is essentially a straight side of the vertical pillar 1b and may have two narrow convex sides 1b".
  • the log splitter with improved sliding guides according to the invention is preferably constructed so that a first pair of sliding plates 5, 5' is in direct contact with the base (carrier) plate 4, which moves along the convex sides 1b" of the guide 1b' limited between two parallel distancing elements 6, 6', and a second pair of sliding plates 8, 8', which are parallel to the first pair of the sliding plates 5, 5'. Additionally, a pair of thin distancing elements 7 and 7' may be provided between the distancing elements 6 and 6' and between the second pair of the sliding plates 8 and 8'. The function of the thin distancing elements is important when sliding plates despite the presence of graphite or graphene start showing wear and thin out.
  • airiness between the sliding plates and the guide may increase.
  • said airiness can be reduced with removal of the said thin distancing elements.
  • the first distancing element 6 preferably has five fifth holes 6a, which are coaxial with first holes 4a on one side of the plate 4 and third holes 5a of the first sliding plate 5.
  • the second distancing element 6' preferably has five sixth holes 6a', which are coaxial to second holes 4a' on the other side of the plate 4 and fourth holes 5a' of the second sliding plate 5'.
  • Parallel to the first pair of distancing elements 6 and 6' the pair of thin distancing elements 7 and 7' is provided.
  • the first thin distancing element 7 preferably has five seventh holes 7a, which are coaxial with fifth holes 6a of the first distancing element 6.
  • the second thin distancing element 7' preferably has five eighth holes 7a', which are coaxial with sixth holes 6a' of the second distancing element 6'.
  • the third sliding plate 8 preferably has five ninth holes 8a, which are coaxial with seventh holes 7a of the thin distancing element 7.
  • the fourth plate 8' preferably has five tenth holes 8a', which are coaxial with eighth holes 7a' of the thin distancing element 7'.
  • the first mounting plate 9 preferably has five eleventh holes 9a, which are coaxial with ninth holes 8a of the third sliding plate 8.
  • the second mounting plate 9' preferably has five twelfth holes 9a', which are coaxial with tenth holes 8a' of the fourth sliding plate 8'.
