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 counter knife is mounted on a counter knife carrier on which it is fixable.
  • the counter knife holder for its part, rests in a console that supports the machine stand is firmly connected, for example by a Welding. Since the counter knife is a subject of wear, it must be replaced from time to time. Due to the fixation on Counter-knife holder will wear it together with appropriate wear the counter knife carrier removed, in that it is from the side the chipper is pulled out.
  • a transfer plate Between the last lower feed roller in the feed direction and the console is a transfer plate. This is - like that console mentioned - firmly connected to the machine stand, for example by welding. It rests with its in the feed direction downstream end on the console. However, remains between this End and the counter knife a certain space. This is necessary so that the counter knife together with the counter knife carrier if necessary - As mentioned above - can be pulled out to the side.
  • the invention has for its object a chipper according to the To design the preamble of claim 1 such that a wedging between Transfer plate and counter knife is avoided, but that Transfer plate its function of the correct transfer of wood from the Feed channel in the knife area fulfilled perfectly.
  • a compensating piece that on Counter knife or fixed to the counter knife holder.
  • This Compensating piece bridges the gap that is initially in unlocked state between the downstream end of the Transfer plate and the counter knife is present.
  • the compensation piece can be made of a special material so that it is one Resists deformation when the chopping rotor is struck.
  • 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.
  • Said unit 3 comprises the following elements: this can be seen Counter knife 3.1. This is mounted on the counter knife carrier 3.2 and with this firmly connected, for example by screwing.
  • the counter knife carrier 3.2 rests on or in the bracket 3.3. This is in present case of substantially L-shaped profile.
  • Console 3.3 and Transfer plates 4 are each firmly connected to the machine stand, for example by welding. Between the counter knife carrier 3.2 and there is an intermediate layer 3.4 of the console 3.3. This allows one easy, sliding pulling out of counter knife holder 3.2 together with Counter knife 3.1.
  • the transfer plate 4 is visibly on the console 3.3, namely on the upper surface of one leg.
  • Console 3.3 and Transfer plate 4 can be firmly connected to one another, for example by screwing or welding ⁇ However, there is also a free contact of the transfer plate 4 on the console 3.3 possible.
  • the compensating piece 3.5 according to the invention is very crucial. This bridges the gap between the in the feed direction downstream end of the transfer plate 4 and the counter knife 3.1.
  • the compensation piece 3.5 is in cross section in essentially L-shaped.
  • other profiles are also conceivable, for example a boomerang shape or the shape of a quarter quadrant of a ring.
  • the compensating piece can be fixed on the counter knife carrier 3.2, for example by screwing. If the counter knife 3.1 is worn, it will together with the counter knife carrier 3.2 and the compensating piece 3.5 pulled out of the side of the machine, in a direction parallel to the axis the chopping rotor 1 and thus also to the axis of the feed roller 2.1.
  • the shape of the counter knife carrier 3.2, the console 3.3 and the Intermediate layer 3.4 can also be different than shown here. So it could Interface between the elements mentioned, for example Circular cylindrical surface, or the console 3.3 could be the shape of a Have seen boomerang, again in cross-section.
