Definitions

  • the present invention relates to a root chipper , which re ⁇ moves root swellings from a log, of that kind which is set forth in the preamble of the following claim 1.
  • Th machine which removes root swellings from a log.
  • Th machine comprises a support device having support members, which retain the log in a fixed position, as well as carryin members able to lower the root portion of the log towards a rotating milling unit, while the log is rotated by means mounted in said support members, the result being that the root end assumes a cylindrical shape.
  • the German Offenlegungschrift 2 920 579 also relates to a root chipper, which comprises an annular rotor having a pair of milling tools, through which rotor a log having root swel lings is pushed in order to give the root end a cylindrical shape. Furthermore, the allowed Norwegian patent application no. 129 668 relates to a rotor having cutters mounted inter- nally.
  • one object of the present invention is to suggest a simple, less expensive, less power-consuming and more silent root chipper.
  • Another object of the invention is to suggest a root chipper, which does not throw chips around and yet allows the operator an ample visual survey of the machining process.
  • a third object of the invention is to suggest a root chipper, which removes the least amount possible of root swelling material to make the log acceptable as a sawing object.
  • a log is preferably fed into the root chipper according to the invention by lowering it laterally towards its support device using a crane.
  • Figure 1 is a perspective view of the root chipper of the present invention having some portions removed in order to elucidate its construction
  • Figure 2 is a vertical longitudinal section along line A-A 5 in Figure 1;
  • Figure 3 is a vertical cross section along line B-B in
  • the root chipper presented in the drawings is used to trim root portions from logs, the swellings of which must be re ⁇ moved before the logs are to be sawed.
  • This root chipper 5 comprises a support device 1, which is mainly horizontally disposed, rests on legs la, has a rectangular shape and is made of U-shaped steel beams.
  • Three V-shaped support members 2 for a root log 8 are fastened to the upper face of support device 1 and are designed to let root log 8 rest in a de ⁇ finite position.
  • One of support members 2 is provided with 8 rolls 3, which are driven by an electric motor 3a and are provided with sharp axially oriented surface elevations.
  • electric motor 3a rotates rolls 3
  • a root log placed on support members 2 starts rotating in its fixed position.
  • root portion 9 of the root log abuts a stop 4, which by means of legs 4a is fastened to the left end of support device 1 ( Figure 2) .
  • support device 1 is provided with a frame 5, which is movably disposed in support device 1 in its plane.
  • Two beams of the frame are movably disposed in the U-shaped portions of the beams of support device 1.
  • Frame 5 can be 15 moved to and fro between two end positions, roughly between support 2, which is provided with rolls 3, and stop 4, by means of a hydraulic device 7 having a piston 7a fastened to frame 5.
  • Knife 6 has a parallellepiped cross section and is elevated above frame 5 by means of legs 6a fastened to the frame and thus upper plane surface 6b of knife 6 is parallell with the ax ⁇ ial planes through root log 8 as well as support device 1
  • knife• 6 initially is placed close to support member 2, provided with rolls 3, and a
  • root log 8,9 is lowered onto support members 2 by means of a crane (not shown) or the like, its root portion 9 abutting said stop 4.
  • Electric motor 3a is started and drives rolls 3 in ordarto tarn a major root swelling portion of root por ⁇ tion 9 downwards and below plane 6 b of knife 6, which plane
  • Claim 1 sets forth the general area of protection for the invention.

Abstract

Un coupe-racines de structure simple, peu coûteux à fabriquer, et ayant un fonctionnement silencieux et économique, comprend un dispositif de soutien (1) pour une bûche (8) dont les parties protubérantes de racines (0) doivent être enlevées pour que la bûche puisse être sciée par une scie à châssis ou lors d'autres opérations rapides de sciage. Le coupe-racines comprend également un dispositif (2) et des moyens (3) de support qui coopèrent pour faire tourner la bûche dans une position fixe sur ledit dispositif de support (1). Un bâti (5) portant un couteau (6) dans le dispositif de support (1) est poussé en avant par un dispositif hydraulique (7, 7a) et ce couteau coupe ainsi, dans différentes positions angulaires de la bûche rotative, les parties protubérantes de racines (9). Entre deux et quatre coupes similaires suffisent en général pour préparer la bûche pour l'opération de sciage.
