Definitions

  • the invention relates to a method of processing energy wood, the method comprising the steps of feeding wood to a feed conveyor belonging to a harvesting apparatus, transporting wood by means of the feed conveyor through a feed opening to a feed chamber of the harvesting apparatus, feeding a predefined amount of wood to the feed chamber, after which performing cutting to a desired length by means of a cutting apparatus between the feed chamber and the feed conveyor, and further, the method comprising the step of compressing wood to reduce its volume and to form a wood bundle.
  • the invention further relates to a harvesting apparatus for processing energy wood, which harvesting apparatus comprises a feed conveyor and a feed chamber, and the feed conveyor is arranged to transport wood fed to it through a feed opening to the feed chamber, a cutting apparatus which is arranged between the feed conveyor and the feed chamber and which cutting apparatus is arranged to cut a wood batch fed into the feed chamber, and further, means for compressing wood to a smaller volume.
  • One bundling machine on the market comprises a feeding table, to which logging residue to be baled is fed and which transports the logging residue to a feed chamber in which the logging residue is grabbed by jaws which compress the logging residue and, at the same time, pull it forward towards a tying station at the outlet end of the feed chamber, where the created logging residue bundle is tied with a string.
  • the machine in question makes a continuous logging residue bundle which, after tying, is cut by a chain saw into bundles of predefined length at the tail end of the apparatus.
  • a problem with the machine in question is that other functions of the machine, such as feeding and tying, are interrupted during the cutting of the bundle, which is why the use of the machine is not efficient.
  • a further problem is that logging residue must be fed evenly on the feeding table, since too high a feeding rate blocks the machine, and correspondingly, with too low a feeding rate, the machine does not start to make the bundle at all.
  • a suitable amount of wood must continuously be on its way into the feed chamber. This hampers essentially the work of the machine operator and slows down the operation of the machine.
  • Yet another difficulty with the machine is that the finished tied bundle is cut with a chain saw. In such a case, stresses in the compressed bundle relax due to cutting and may break the chain saw. If there are slanting wood ends at the cutting point, they can easily pry the saw blade to the side and may damage the operation of the saw.
  • a logging residue bundling machine that has several parallel rollers and arranged in a circle. Logging residue to be bundled is fed into a feed chamber between the rollers through a feed opening above the rollers. The rotating rollers work the logging residue into a roll that is, at the end, tied and dropped into the forest to be collected later.
  • a difficulty in this solution is that logging residue must be fed evenly into the feed chamber surrounded by the rollers along the entire length of the chamber, because otherwise the thickness of the bundles will not be even. Further, the machine operator must monitor the moment when the feed chamber is full. Logging residue cannot be fed during tying and the removal of the ready bundle. Thus, the feeding and use of the apparatus in question is slow and difficult. Another drawback is that the apparatus is not at all suitable for processing long poles, but can only be fed relatively short branches and twigs. [0007] It is an object of the present invention to provide a new type of method and harvesting apparatus for processing energy wood.
  • the method of the invention is characterized by moving by means of a turning feeding blade in the feed chamber a cut wood batch away from the feed opening in transverse direction to the feed direction.
  • the apparatus of the invention is characterized in that the feed chamber has a feeding blade which is substantially parallel to the feed chamber and substantially of the same length as the feed chamber, and that the feeding blade is arranged to move in substantially transverse direction to the feed direction the wood batch cut by the cutting apparatus aside from the feed opening and out of the way of a new wood batch being fed in to the feed chamber.
  • An essential idea of the invention is that a suitable batch of the wood being processed is fed into the feed chamber from the feed opening, after which cutting is done by a cutting apparatus arranged at the feed opening. After cutting, the tumably arranged feeding blade in the feed chamber moves the wood batch in the feed chamber at the feed opening to the side for further processing, and a new wood batch can again be fed substantially immediately into the feed chamber.
  • an essential idea of a preferred embodiment of the invention is that the cutting apparatus comprises a disc-like blade that is arranged to move back and forth. Cutting by the guillotine principle is very fast. In addition, cutting is reliable and inexpensive. In addition, an advantage is that the feed opening can be closed by means of the cutting blade so as to prevent the passing of the material through the feed opening. The feed conveyor can then be a continuous conveyor. [0012] An essential idea of a second preferred embodiment of the invention is that the feeding blade is arranged to move back and forth and that cutting is arranged so that the feeding blade moves the cut wood batch alternately to different sides relative to the feed opening. When the drives of the feeding blade and the cutting blade are suitably synchronized, feeding and cutting are very fast.
  • a compression chamber is arranged, being defined by jaws that press against each other and compress the wood fed into the compression chamber from the feed chamber and work it into a wood bundle. Further, when closed, the jaws form a wall between the feed chamber and the compression chamber, and when the compression chamber is emptied, cut wood batches can be moved by means of the feeding blade for intermediate storage on top of the jaws.
  • the compression chamber can again receive wood, the jaws are opened and the feed chamber is again open to the compression chamber and by means of gravity and the feeding blade, wood can enter the compression chamber for further processing. This way, new wood can continuously be fed into the feed chamber and cut and stored temporarily there while the compression chamber is emptied. Using two chambers thus evens out the material flow being fed.
  • the harvesting apparatus can be short and compact.
  • the terms 'energy wood' and 'wood' refer to different kinds of logging residue, such as branches, twigs, and top refuse, and also to longer wood with a larger diameter, such as logs, and to building waste wood, for instance.

  • the harvesting apparatus is in its transport position, in which it is longitudinal to the forest machine and hampers off-road driving as little as possible.
  • a feed conveyor 3 of the harvesting apparatus is turned on top of the harvesting apparatus and similarly, a discharge plate 4 at the tail end of the apparatus is in its up position, thus making the harvesting apparatus as short as possible.
  • the harvesting apparatus is arranged on the carrier 2a of the forest machine in such a manner that it can be turned around a vertical axis A from the transport position to the operating position.
  • the operating position is shown in Figure 1 b.
  • the harvesting apparatus In its operating position, the harvesting apparatus is transverse to the longitudinal axis of the forest machine.
  • the feed conveyor 3 and the discharge plate 4 are down. Energy wood 11 to be processed is then lifted by means of a loader 5 of the forest machine onto the feed conveyor.
  • On the bottom surface of the feed conveyor there is a conveyor chain 7, belt or the like running around turning rolls 6a and 6b marked with dashed lines that moves in the direction B towards a feed opening 8.
  • the feed conveyor has a feed roll 9 arranged at the feed opening and on top of the conveyor chain to press the wood being fed in such a manner that it fits through the feed opening inside a feed chamber 10. The feed roll is rotated in the direction C.
  • the feed roll may be protrusions on the surface of the feed roll to increase friction between the roll and wood.
  • the feed roll is arranged in such a manner that its height can change according to the wood being fed.
  • Cutting is preferably done by means of a guillotine-type disc-like cutting blade 13 that is moved in a transverse direction D to the feeding direction.
  • the wood is moved by means of a feeding blade to be described later to a compression chamber 14 below the feed chamber.

  • the bundle is supported by the discharge plate 4. After tying, the wood bundle is dropped into the forest.
  • a normal forest tractor later moves the bundles to the side of a forest road, where they are allowed to dry before being transported for chipping. The processing breaks the wood bark, which speeds up the drying of the bundles in a preferable manner.

Abstract

L'invention concerne un procédé de collecte et de traitement de bois à usage énergétique et un appareil correspondant. L'appareil de collecte et de traitement du bois (1) comprend un tapis d'alimentation (3) qui transporte, par une ouverture d'alimentation (8), le bois devant être traité vers une chambre d'alimentation (10). Après qu'un lot approprié a été amené, on procède à la coupe du bois au moyen d'un appareil de coupe (12) entre le tapis d'alimentation (3) et la chambre d'alimentation. Cette chambre d'alimentation comprend une lame d'alimentation (23) qui peut tourner, sensiblement parallèlement à la chambre d'alimentation et avec une longueur sensiblement égale à celle de la chambre d'alimentation et qui après la coupe éloigne latéralement le lot de bois de l'ouverture d'alimentation, ce qui permet d'amener, par l'ouverture d'alimentation, un nouveau lot de bois dans la chambre d'alimentation. Selon un mode de réalisation préféré, la lame d'alimentation tourne en avant et en arrière, éloignant ainsi le bois coupé de l'ouverture d'alimentation en alternance sur différents côtés par rapport à l'ouverture d'alimentation.
