Description
Technical field
The utility model relates to the cutting-tool engineering field, refers in particular to a kind of built up gear cutter.
Background technology
In the park or roadside or forest kind expired flowers, plants and trees, after these trees branches and leaves were pruned, these discarded branches needed manual work to pulverize; And artificial these branch spended times of pulverizing are long, and cost is high, weak effect; So people have just invented a kind of chipper, the cutter that this machine can be through at a high speed rotation branch very fast be cut into multistage, improved operating efficiency; Reduced processing cost, so the quality of cutter directly affects the effect of pulverizing branches and leaves, at present; The gear teeth of the existing employed cutter of chipper are straight-tooth, and this cutter can be pulverized discarded branches and leaves, but can't pulverize very thoroughly to some big or solid branches and leaves; Can't reach the required requirement of people, and need integral replacing later on when tool damage, and the cost of cutter is expensive.
Summary of the invention
The utility model provides a kind of simple in structure, easy to assembly, high efficiency, pulverizing branches and leaves built up gear cutter completely.
The purpose of the utility model is achieved in that a kind of built up gear cutter; Comprise that the gear cutter that is enclosed within on the axle connects through key; On the step axle, be with a plurality of gear cutter unit and connect into the built up gear cutter through key; Each gear cutter unit is along circumferentially being provided with a plurality of gear teeth, and the gear teeth cutting edge of adjacent two gear cutter unit is parallel to each other or intersects certain angle or antarafacial, and the axis of gear cutter unit is provided with the through hole that matches with the step axle; The sidewall of through hole is provided with the keyway that matches with key, and the face of cylinder of step axle is provided with keyway.
It can be that the two-end-point of line segment joins or the line segment mutual dislocation that the gear teeth cutting edge of above-mentioned adjacent two gear cutter unit is parallel to each other.
Above-mentioned step axle has three grades of steps, and middle step is provided with the keyway that matches with key, and the outside of big footpath step circle cylinder is provided with three through holes to being outside equipped with the triangle boss that drift angle is an arc transition on three angles of triangle boss vertically.
Above-mentioned gear cutter unit is straight-tooth flywheel knife unit or helical teeth flywheel knife unit or bevel gear cutter unit.
Above-mentioned straight-tooth flywheel knife unit, bevel gear cutter unit and helical teeth flywheel knife unit permutation and combination arbitrarily are enclosed within on the middle step.
Gear teeth cutting edge when above-mentioned helical teeth flywheel knife unit is connected with helical teeth flywheel knife unit is in the shape of the letter V.
The utility model is compared the outstanding and beneficial technical effects of prior art:
1, the utility model adopts the built up gear cutter, makes branches and leaves under the effect of this cutter, pulverize more thoroughly.
2, after the gear cutter of the utility model damaged, it was simple, with low cost to change cutter.
3, the utility model is simple in structure, and is easy to assembly, and high efficiency is in the similar machines of chipper or pulverizing branch.
