Definitions
- the invention relates to a knife ring chipper for machining Wood chips.
- a chipper is for example from DE 32 47 629 C1 known.
- Such a chipper is constructed as follows: it also includes a knife ring a variety of knife packages. Each knife pack has a knife that points with its cutting edge inwards, and that against the radial direction is inclined.
- the knife ring encloses a rotor which is coaxial to the Knife ring is arranged.
- the rotor has a large number of rotor blades on.
- Each rotor blade carries a strip-shaped at its outer end Splitting knife, which is arranged axially parallel and over the width of the Rotors extends.
- the rotor - essentially in the axial direction - Wood chips are fed to the outside against the knife packs hurls.
- the mentioned splitting knives work with the knives of the Knife rings together by breaking the chips into fine chips.
- the radially outer dimension of the splitting knife is a very critical measure. It must be set precisely and in this setting too being held. In any case, it must be prevented that the Splitting knives protrude radially too far, otherwise they will stick with the knives of the knife ring collide.
- the splitting knives are attached to the rotor blades by means of screws.
- the splitting knives have elongated holes that extend in the radial direction extend, and through which the screws are passed. This Elongated holes are necessary because the splitting knives change over the course of the Wear time, and because of that a certain radial adjustment outside after a certain period of operation is necessary.
- the Connection with the fastening screws can therefore only one be frictional. But this is critical because it is due to the high centrifugal forces for a slow migration of the splitting knife radially can come out.
- the invention has for its object a knife ring chipper, in particular to design its rotor such that the radial position of the Splitting knife is reliably maintained.
- Each screw connection is namely according to the invention with a wedge-shaped element through which the fastening screw is passed through and that - in an axially perpendicular cut seen - tapered in a radial direction from the inside to the outside.
- This has the following effects: centrifugal forces occur during operation, as mentioned. These act on the splitting knife, but also on the wedge elements. This both strive to move outside, but it does already with a minimal hike radially outwards due to the Wedge effect of the wedge element to tighten even more tightly Screw connection. This prevents the individual splitting knife from becoming a noteworthy traveling movement radially outwards.
- Figure 1 shows a cross section through a knife ring chipper.
- Figure 2 shows a section of the knife ring in a view in Axis direction and greatly enlarged compared to Figure 1.
- Figure 3 shows a plan view of the rotor in the axial direction.
- FIGS. 4a-4c each show a rotor blade with different ones Positions of the associated splitting knife.
- Figure 5 shows a wedge element - compared to the representations of Figures 4a - 4c enlarged.
- the knife ring chipper shown in Figure 1 comprises a fixed Knife ring 1.
- the knife ring surrounds a rotor 2, which is on a Rotor shaft 2.1 is seated. Knife ring 1 and rotor 2 are coaxial with each other arranged.
- the knife ring 1 is permanently installed in a housing 3.
- the Housing 3 has an inlet 3.1 for feeding wood chips, also a chip outlet channel 3.2, which surrounds the knife ring.
- each knife package has a knife 1.1. This is between a knife holder 1.2 and a clamping plate 1.3 clamped. Each Knife package is in the present case with a so-called stick knife 1.4 provided.
- the invention can also be used without knife packs Use a stick knife.
- Blades of the rotor are shown in phantom lines. See the shovel 2.1, which carries a splitting knife 2.2. It can be seen that the radial position of the Splitting knife 2.2 is a critical measure. If this is exceeded, then comes there is a collision between the splitting knife 2.2 and the knife 1.1 of the Knife ring 1.
- Each rotor blade 2.1 has an elongated hole 2.3. It is also a screw 2.4 provided. This is passed through the slot and into one the corresponding threaded hole is screwed into the splitting knife 2.2.
- a wedge ledge 2.5 On the key component is a wedge ledge 2.5. This is between the head of the Screw 2.4 and the rotor blade interposed. The shape of the wedge ledge 2.5 can be seen from FIG. 5. It is wedge-shaped, in that sense that it tapers radially from the inside out.
- the rotor blade is in the outer region shown is surrounded by a wear plate 2.6. This is through screws 2.7, 2.8 screwed with associated nuts to the rotor blade 2.1.
