Abstract

The woodchip chopper (1) has a rotor (3) on which a cutting blade (2) is fitted for working in conjunction with a counter steel (8), fitted in the vicinity of wood feed-in rollers. To avoid adjustment of the counter steel and blade during sharpening, an edge area, which thrusts up to the blade edge (6) is raised parallel with the blade first side surface (18), which is located against the rotor side surface (15).

Description

PATENTKRAV 1. Flishugger, som har en rotor hvorpå knive er monteret for at samvirke med et modstål, der er monteret på en fast ramme i umiddelbar nærhed af indføringsvalser for derved at afskære flis af træ, der indføres af indføringsval seme med en hastighed, der er afpasset efter rotorens omdrejningstal, hvilke knive er placeret i tilknytning til en åbning i rotoren hvor igennem afhugget flis bortledes, hvilket modstål er monteret forskydeligt for at etablere justering af afstand mellem knivæg og modstål kendetegnet ved, at hver kniv er monteret med en første sideflade i anlæg mod rotorens sideflade, der er tilnærmelsesvis vinkelret på træets indføringsretning, samt en modstående anden sideflade, at de to sideflader forløber konvergerende i retning væk fra en kantflade, hvor knivæggen er tilvejebragt, at knivæggen er dannet imellem den anden sideflade og en skrå kantflade mellem de to sideflader, og at den anden sideflade i et kantområde, der støder op til æggen, er parallel med den første sideflade. 2. Flishugger ifølge krav 1,kendetegnet ved, at kantområdet har en bredde som modsvarer en grænse for tilladt afslibning ved slibning af kniven, og at kantområdet er mellem 10 og 40 mm. fortrinsvis mellem 15 og 25 mm. 3. Flishugger ifølge 1 eller 2, kendetegnet ved, at afstand mellem modstålet og knivæggen er mellem 0,5 og 0,7 mm. 4. Flishugger ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at modstålet har aflange huller for modtagelse af montagebolte, der er fastskruet i rammen. 5. Flishugger ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at hver kniv er monteret på rotorens sideflade ved hjælp af bolte der passerer gennem cylindriske huller i kniv og rotor. 6. Flishugger ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at der er tilvejebragt 2-4 knive i rotoren. 7. Flishugger ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at hver kniv er monteret med sin æg i en stort set radial orientering. 8. Kniv til en flishugger ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at den har en første sideflade for anlæg mod rotorens sideflade samt en modstående anden sideflade, at de to sideflader forløber konvergerende i retning væk fra en kantflade, hvor knivæggen er tilvejebragt, at knivæggen er dannet imellem den anden sideflade og en skrå kantflade mellem de to sideflader, og at den anden sideflade i et kantområde, der støder op til æggen, er parallel med den første sideflade. 9. Kniv ifølge krav 8, kendetegnet ved, at kantområdet er dannet ved slibning, ffæsning eller anden mekanisk bearbejdning for at etablere parallelitet i et kantområde med en ønsket bredde.PATENT REQUIREMENT 1. Wood chipper having a rotor on which knives are mounted to cooperate with a countermount mounted on a fixed frame in the immediate vicinity of feed rollers, thereby cutting off wood chips fed by feed roller at a rate which is adapted to the rotor speed, which blades are placed adjacent to an opening in the rotor through which chipped chips are discharged, which resistor is slidably mounted to establish adjustment of the distance between the knife wall and the resistor, characterized in that each knife is mounted with a first side face abutting the side surface of the rotor which is approximately perpendicular to the direction of insertion of the tree, and an opposing second side surface, the two side faces converge in a direction away from an edge surface, where the knife wall is provided, the knife wall is formed between the other side surface and an inclined edge surface. between the two side faces, and the other side face in an adjacent edge area the egg, is parallel to the first side surface. Chipper according to claim 1, characterized in that the edge area has a width corresponding to a limit for allowable grinding when grinding the knife and that the edge area is between 10 and 40 mm. preferably between 15 and 25 mm. Wood chipper according to 1 or 2, characterized in that the distance between the resistor and the knife wall is between 0.5 and 0.7 mm. Wood chipper according to any one of the preceding claims, characterized in that the resistor has elongated holes for receiving mounting bolts screwed into the frame. Chipper according to any one of the preceding claims, characterized in that each knife is mounted on the side surface of the rotor by means of bolts passing through cylindrical holes in the knife and rotor. Chipper according to any one of the preceding claims, characterized in that 2-4 knives are provided in the rotor. Chipper according to any one of the preceding claims, characterized in that each knife is mounted with its egg in a substantially radial orientation. Knife for a wood chipper according to any one of the preceding claims, characterized in that it has a first side face for abutment against the side face of the rotor and an opposite second side face, that the two side faces extend converging in a direction away from an edge surface, wherein the knife wall is provided that the knife wall is formed between the second side surface and an oblique edge surface between the two side faces, and that the second side face in an edge area adjacent to the egg is parallel to the first side face. Knife according to claim 8, characterized in that the edge region is formed by grinding, milling or other mechanical machining to establish parallelism in an edge region of a desired width.
