Definitions

  • the invention relates to a chopping machine for chopping wood into beating or Root form into wood chips.
  • Such machines are for example known from DE 43 05 120 C.
  • the essential elements of a Such machines are a chopping rotor that has a number of knives on them carries its circumference, which is evenly distributed over the circumference are, also a counter knife, which is assigned to the chopping rotor, and a these two upstream feed channels.
  • the knife rotor the machine can also be equipped with an impact rotor.
  • the Feed channel comprises a number of feed rollers, namely an upper one Row and a lower row, which is the beating or stem-shaped wood of the mentioned knife unit, consisting of chopping rotor and counter knife promote.
  • the spanking or trunks move in the direction of their longitudinal axis fed to the chopping rotor.
  • the named chipper rotor produces chippings that have a certain length have, measured in the feed direction of the wood and thus also at the same time in its grain. This length of wood chips is for the subsequent processing process of importance.
  • the common one Wood chip length is 50 mm. This length depends on the knife board from. With a wood chip length of 50 mm, a knife board of 65 mm necessary. For certain applications, it is desirable To produce wood chips of a different length, especially wood chips shorter length, for example with a length of 25 mm. The move a chipper is such that the chop length is changed so far not possible. To move from a larger to a smaller one To get wood chip length, you could use the wood feed reduce. However, this would result in lower emissions of the Guide the chipper.
  • CH 622 440 describes a machine for comminuting goods. The length the shredded parts can only be changed and replaced bring the cutting discs themselves.
  • the invention is therefore based on the object of a chopping machine to design the preamble of claim 1 such that changing the Wood chip length is possible without much effort.
  • the inventors resorted to a very simple measure.
  • the main idea is to design the chopping rotor in such a way that the number of knives can be changed. If you want large chips Generate length, so choose a relatively small number of Knives. If, on the other hand, you want to produce wood chips of short length, so increase the number of knives in the chopping rotor. It must always do so be made sure that the chopping rotor is a largely closed outer Has outer surface. This is done in that appropriate Components are provided that work with a small number of knives the peripheral area of the chopping rotor can be inserted, at which otherwise - with a larger number of knives - there are also knives.
  • the chopping machine shown in FIG. 1 comprises a chopping rotor 1- shown in dashed lines. It also includes a feed channel 2 and this is formed from an upper and a lower row of feed rollers. A of which is the last lower feed roller 2.1 in the feed direction.
  • a unit 3 can also be seen, which among other things. contains a counter knife and the to be described in detail below.
  • a transfer plate 4 is arranged between the last lower feed roller 2.1 and the unit 3.
  • the chopping rotor 1 shown in FIG. 2 has six knife stations I to VI.
  • the chopping rotor 1 is constructed in such a way that the number of knives is arbitrary can be reduced. In general, you will always be at a reduction choose such an arrangement of the knife stations that the mutual Distances in the circumferential direction are the same size.
  • the individual knife station comprises the following components: A knife 1.1, a clamping plate 1.2 and a jacket plate 1.3.
  • the clamping plate 1.2 is articulated on the jacket plate 1.3 by means of a joint 1.4.
  • the chopping rotor 1 has a circular plow circle 1.5.
  • the outer surface of the individual knife stations describes a spiral 1.6, formed from the knife 1.1, the clamping plate 1.2 and the outer plate 1.3.
  • a blind plate must be used instead. This is not shown here. However, it must have a lateral surface 1.7, which in turn has a spiral course, just like the lateral surface 1.6.
  • the outer surface 1.7 is drawn in radially more than the outer surface 1.6, so that a knife board 1.8 results, which in the present case is 65 mm.
  • the blind plate can be attached to the body of thehackrotors are attached, for example by means of a Dovetail profiling.
