Abstract

The invention relates to raw material processing equipment in papermaking industry, artificial board manufacturing industry and the like, in particular to a tree root crusher knife tackle used in equipment used for cutting off and crushing tree roots. The tree root crusher knife tackle comprises a rotary knife roll and a dead knife, wherein the knife roll is arranged in a crushing cavity of a tree root crusher; the dead knife is located at one side of the knife roll; fly knives matched with the dead knife are arranged on the outer cylindrical surface of the knife roll; the cutting edge of each fly knife is convexly triangular; a plurality of concave triangles arranged along the axial direction of the knife roll form the cutting edge of the dead knife in shape; and the cutting edges of the fly knives and the cutting edge of the dead knife are matched with each other. The tree root crusher knife tackle has the advantages that a tree root crushing effect is good; the crushing efficiency is high; and the service lives of the knives are long.

Description

The broken machine knife group of tree root

Technical field

The present invention relates to the raw material processing of the industries such as papermaking, wood-based plate manufacturing, specifically a kind of broken machine knife group of tree root that tree root is cut off, uses in the broken equipment of being used for.

Background technology

Employed cutter group parts generally include the rotatable rotor that is placed with fly cutter in the common plant stem disintegrating apparatus, and the bed plate that cooperates with fly cutter, and fly cutter and bed plate cooperatively interact by linear edge usually, and material is carried out shearing-crushing.But when this equipment was used for the processing tree root, because tree root size, shape, seeds vary, its wood fibre direction was disorderly and unsystematic, and the wood-fibred of same tree root different directions twines mutually, and the use existing equipment is difficult to cut off fragmentation and obtains qualified wood chip.

Summary of the invention

The present invention wants the technical solution problem to be, provides the tree root that a kind of crushing effect to tree root is good, crushing efficiency is high, cutter life is long broken machine knife group.

The broken machine knife group of tree root of the present invention includes a bed plate that is installed in the rotor of the rotation in the tree root crushing chamber of crusher and is positioned at rotor one side, is placed with the fly cutter that cooperates with bed plate on the external cylindrical surface of rotor; The triangle that is shaped as evagination of fly cutter cutting edge, the triangle that is shaped as a plurality of indents along the rotor axially-aligned of bed plate cutting edge, the fly cutter cutting edge matches with the bed plate cutting edge.

Described fly cutter is square, and its foursquare four bights consist of four leg-of-mutton fly cutter cutting edges with right angle drift angle.Four fly cutter cutting edges in four bights can be used alternatingly, with tool life.

Described fly cutter is arranged along helix on rotor.

Described fly cutter is arranged on many helixes.

Advantage applies of the present invention exists:

1, adopts leg-of-mutton edge structure, not only increased the cutting edge length in the rotor length range, and can the material fiber on a plurality of directions effectively have been cut, improved crushing effect and working (machining) efficiency;

2, the fly cutter spiral is arranged on the rotor, alternately cooperates with bed plate, has alleviated the suffered impulsive force of bed plate and rotor, is conducive to improve equipment life;

3, adopt foursquare fly cutter structure, form four interchangeable cutting edges at a fly cutter, when cutting edge wearing and tearing, the fly cutter half-twist can be used other cutting edges to continue cutting, thereby greatly prolong cutting-tool's used life, saved equipment cost.

Fig. 2 is the fly cutter of the embodiment of the invention and the cutting edge structure schematic diagram of bed plate.

The specific embodiment

As shown in the figure, the broken machine knife group of this tree root includes a bed plate 3 that is installed in the rotor 2 of the rotation in tree root disintegrating machine 1 crusher chamber and is positioned at rotor one side, is placed with the fly cutter 4 that cooperates with bed plate on the external cylindrical surface of rotor.Fly cutter 4 is arranged along many helixes on rotor 2.As shown in Figure 2, fly cutter 4 is square, and its foursquare four bights consist of four leg-of-mutton fly cutter cutting edges 41 with right angle drift angle.The triangle that is shaped as a plurality of indents along the rotor axially-aligned of bed plate cutting edge 31, the fly cutter cutting edge matches with the bed plate cutting edge.
