Definitions

  • the apparatus contains a chipping vehicle, at the mobile boom head of which a cutting and chipping unit is installed for cutting trees and converting them into chips. Produced chip is shifted over from chipping unit into a chip container on the vehicle.
  • Chipping machines of the s.c. master's series are generally small tractor-mounted machines getting their driving power from the power take-off of the tractor and by means of which forest owners, making delivery loggings, can produce wood chips themselves of trees of own harvest.
  • Apparatus related to converting standing trees into wood chip are known a.o. from US patents No. 3,651,845 and 3,646,976. They are not applicable for thinning, since their chipping method is space-taking or they cannot be driven close to the tree. They are practicable for for converting either a single tree in a clearing or all directly oncoming trees into wood chip, but it requires quite a passable terrain.
  • Fig. 1 shows the chipping vehicle.
  • Fig. 2 shows the cutting and chipping unit of the chipping vehicle
  • Fig. 3 shows the gripping and delimbing rolls of the tree to be converted into wood chip
  • Fig. 4 shows the delimbing, debarking and chipping unit
  • Fig. 5 shows the delimbing blades
  • Fig. 6 shows the cutting and chipping blade disc
  • Fig. 7 is the cross-section of the chipping blade
  • Figure 1 illustrates a chipping vehicle 1 furnished with a chip container 2 and a hydraulic boom 3 with a chipping unit 4 at its top, by means of which a tree 6 to be converted into wood chip is cut and chipped in standing position, support rolls 16 holding tree upright and delimbing, steering and feeding it to the blade in the chipping unit.
  • Produced wood chip is shifted along a conveyor 5 to the chip container 2.
  • Chipping unit 4 is furnished with outriggers 8.
  • FIG. 2 shows the chipping vehicle with a chipping unit with outriggers 8 and a tree gripping jaw 10 driven by a hydraulic cylinder 7.
  • the jaw presses the trunk against part 11.
  • the tree is cutted with a combination 13 consisting of chipping blades 25 on a saw disc which are manipulated by a hydraulic cylinder 9 and rotated by a hydraulic motor 12.
  • the outer of edge of saw disc is formed as a circular saw.
  • blades 25 convert the standing tree into chips. At least during chipping, it is preferable to keep the blade blame assembly in slanting position, at angle of up to 45° with the tree.
  • Produced chip is collected with a funnel receptacle 14 and shifted along conveyor 5 to wood chip container 2 on the chipping vehicle.
  • FIG. 3 shows support and delimbing rolls 15,16, by means of which the trunk is kept upright and fed into the chipping unit while making chip.
  • Rolls 15,16 delimbe the tree when it is fed downward upon chipping.
  • rolls 15,16 are in a position where the direction of their longitudinal axis deviates from the direction perpendicular to the longitudinal axis of the tree.
  • Rolls 15 and 16 are fastened rotatably on levers 17,18 and the rolls can can be moved with relation to the tree in turning the levers 17,18. Rotation of rolls is effected by means of a hydraulic motor.
  • Fig. 4 shows the chipping unit 4 with the blade disc 24 in slanting position, cutting the tree by means of its end bits 26 and chipping blades 25. Chip is produced already upon cutting and ejected by the blade assembly into a collector bin 23 from where it is shifted over, as described, to container 2.
  • the container bottom 22 is robust and moves on the stub as cutting advances and, finally, carries the chipping unit 4 and the tree 6.
  • the chipping unit is fastened to the boom arm 20 with cylinder 21.
  • Blade bar 24 is fixed to frame member 19 by means of a bar 27, against the roll 28 of which the tree is supported.
  • Turnable arms 29 are fixed to frame member 19 by an articulation 35. One of the arms 29 is behind the tree.
  • the arms embrace the tree with a strong grip for support and put chipping unit into working position.
  • the arms are furnished with hydraulically rotatable debarking rolls. After cutting, the tree is put into rotation by means of rotating and inclined feeding rolls 16.
  • Feed roll arms 31 open and adjust according to tree diameter.
  • Delimbing rolls 32,33 are fastened to same arms and are also adjustable according to tree diameter.
  • Blades 32,33,34 can be spring-loaded, whereby leaned against the trunk they cut off oncoming limbs. The blades turn around a fulcrum pin 36.
  • Figure 6 illustrates a blade disc 24 with blade bits 26 along its edge and chipping blades 25 protruding from blade disc upper face. Wood chip is moved from the front of the blade through the disc to its underside and further into the collecting bin ejected by the winglike blade.
  • Figure 7 illustrates as cross-section of the fastening of blade 25 to the blade disc by means of an abuttment bit 35. The chips teared off the tree are slewed from the front of blade through the disc to the its underside.
  • the chipping unit can be furnished with a gripping element to take support from the stub and keep tree upright on the stub and by means of which tree can be lifted and supported during processing, for instance by means of hydraulic cylinders.
  • the tree can be cut also by using a blade, which driven by great power power cuts the tree and then engages ti with the chipping blade.

Abstract

Le procédé et l'appareil décrits servent à découper un arbre (6) en copeaux au moyen d'un désintégrateur (4) attaché à un véhicule (1). Le désintégrateur (4) attaché au véhicule (1) est placé contre le pied (6) de l'arbre et prend appui, grâce à ses éléments préhenseurs (10, 11) contre le tronc de l'arbre. Après avoir coupé l'arbre (6), le désintégrateur (4) le découpe en copeaux, pendant que l'arbre repose sur sa souche et descend progressivement contre les couteaux (13) du désintégrateur par gravité ou sous l'action d'un appareil d'avance (15, 16). Le désintégrateur (4) prend appui sur le sol ou contre le pied de l'arbre. Les copeaux produits sont transportés par un transporteur combiné au désintégrateur (4) jusque dans un conteneur (2) pour copeaux se trouvant dans le véhicule (1). Les opérations préalables d'ébranchage ou d'écorçage de l'arbre (6) sont effectuées par des lames ou par des couteaux à tambours (16) situés au-dessus du désintégrateur.
