Abstract

The utility model discloses an arc trees beam knife, including the arc, fix the knife face at the arc concave surface, fix the handle at the arc convex surface. The edge of a knife on the knife face is the cockscomb structure, and the cockscomb structure edge of a knife keeps unanimous radian with the arc. The base is connected to the lower extreme of knife face, 6 screw holes that are distributing of symmetry on the base. 6 screw holes that are distributing to the central line bilateral symmetry of arc, correspond with screw hole on the base, and the knife face passes through the screw fixation with the arc. The utility model discloses labour saving and time saving, high with bark laminating degree, the be liable to change knife face, have combine simple, flexible operation, low in production cost's characteristics.

Description

A kind of arc tree rossing knife

Technical field

This utility model belongs to forestry technical field of tools, more particularly to a kind of beam knife struck off to trees.

Background technology

The important measures that the thick bark from old tress of forest is self-employed tree cultivator's prevention and elimination of disease and pests are struck off, its usual instrument is with the little of handle The beam knife of hoe shape, or the improved beam knife with sawtooth, this kind of cutter is little with bark fitting area, wastes time and energy, And be difficult to change after edge of a knife passivation.

The content of the invention

To solve the problems referred to above that existing beam knife is present, this utility model provides a kind of arc tree rossing knife, its The technical scheme for being adopted for：The beam knife includes arc, is fixed on the knife face of arc concave surface, is fixed on arc convex surface Handle.The edge of a knife on knife face is serrated, the radian that serrated edge is consistent with arc.The lower end connection bottom of knife face Seat, it is symmetrical on base to be dispersed with 6 screw holes.The centrage both sides of arc symmetrical and are dispersed with 6 screw holes, with base On screw hole correspondence, knife face is screwed with arc.

Because knife face is curved, the contact area with bark is increased, it is time saving and energy saving；Serrated edge is easily scraped slightly Bark from old tress；Knife face is screwed with arc, and split-type design is conveniently replaceable knife face, saves cost.

Fig. 3 is this utility model knife face structural representation.

In figure, 1, arc 2, knife face 3, handle 4, the edge of a knife 5, base 6, base screw hole 7, arc screw hole 8, spiral shell Silk.

Specific embodiment

This utility model is described further below in conjunction with the accompanying drawings：

As shown in Figure 1, Figure 2 and Figure 3, arc tree rossing knife of the present utility model, including arc 1, is fixed on arc The knife face 2 of the concave surface of plate 1, is fixed on the handle 3 of the convex surface of arc 1.The edge of a knife 4 on knife face 2 is serrated, serrated edge 4 with The radian that arc 1 is consistent.The lower end connect base 5 of knife face 2, it is symmetrical on base 5 to be dispersed with 6 screw holes 6.Arc The centrage both sides of plate 1 symmetrical and are dispersed with 6 screw holes 7, corresponding with the screw hole 6 on base 5, and knife face 2 leads to arc 1 Cross screw 8 to fix.

Claims

1. a kind of arc tree rossing knife, including arc, is fixed on the knife face of arc concave surface, is fixed on arc convex surface Handle, it is characterised in that：The edge of a knife on knife face is serrated, the radian that serrated edge is consistent with arc, knife face Lower end connect base, it is symmetrical on base to be dispersed with 6 screw holes；The centrage both sides of arc symmetrical and are dispersed with 6 spiral shells Silk hole, corresponding with the screw hole on base, knife face is screwed with arc.
