Abstract

The invention discloses a tool for chopping reeds into slices, and particularly relates to a scraping knife for only chopping a reed into one slice. The reed scraping knife consists of a knife point, a knife edge, a knife back and a knife handle. The reed scraping knife is characterized in that the knife point is arranged at the front end of the reed scraping knife; the direction of the knife point is perpendicular to the knife back; the outer side of the knife edge is in the shape of a triangular pyramidal wedge; an inclined knife edge is arranged at the inner side of the knife point; the middle section of the reed scraping knife is a straight knife edge; a transition section between the inclined knife edge and the straight knife edge is a sunken circular-arc knife edge; a knife surface section which corresponds to the sunken circular-arc knife edge is a think knife surface which is sunken inwards; the knife back of the sharp knife edge is transited from a 4mm thick part at the front end to a 1.5-2mm thick part of the knife back corresponding to the circular-arc knife edge; the 4mm thick knife back corresponds to the straight knife edge; and the knife handle is arranged at the tail end of the reed scraping knife. The scraping knife can chop a reed with a relatively small diameter of 6-8 mm into one reed strip with width equal to perimeter for knitting, and therefore, a resource utilization rate is increased by the scraping knife, and resource waste is reduced.

Description

A piece of reed thin bamboo strip knife

Technical field

The present invention is that reed is split sheet of instrument by one kind, and a reed is only particularly split into a piece of thin bamboo strip knife.

Background technology

At present, the reed thin bamboo strip knife for using is essentially identical with the shape for splitting thin bamboo strips used for weaving knife, be all the strong vertial knife edge of lengthy motion picture, the thick knife back, Dise knife handle, simply size is smaller, and when splitting the reed thin bamboo strip using reed thin bamboo strip knife, from the diameter of the butt of reed entering knife rives, and one Root reed is divided into two valves from butt to slightly end, after rolling softness through stone roller, just into the reed thin bamboo strip, so that it may woven for reed .When reed diameter is thinner, during below 8mm, being split into the narrower reed thin bamboo strip of two panels with the thinner reed of the reed thin bamboo strip hilt is used for During braiding, braid efficiency is relatively low, therefore, the reed of the thinner 6-8mm of diameter is rejected give it up at present, therefore be a kind of Data is wasted.At present, a reed can't be only split into a piece of reed thin bamboo strip by the reed thin bamboo strip knife for using.

The content of the invention

The technical problem to be solved in the present invention is to provide a kind of thin bamboo strip knife that a reed can be split into a piece of reed thin bamboo strip.

The present invention is adopted the technical scheme that：A piece of reed thin bamboo strip knife, it is made up of point of a knife, blade, the knife back and handle of a knife, and it is special Levying is：There is point of a knife the front end of the reed thin bamboo strip knife, and the sensing of the point of a knife is vertical with the knife back, and the outside of point of a knife is wedge-shaped in pyrometric cone, It is oblique blade on the inside of point of a knife, the stage casing of the reed thin bamboo strip knife is vertial knife edge, the changeover portion of oblique blade and vertial knife edge is the circle of depression Arc cutter sword, knife face section corresponding with depression Roound edge is the thin knife face for caving inward, and the knife back of sharp knife section is by front end Thicker than crossing, vertial knife edge corresponding position is the thick knife back of 4mm, the reed thin bamboo strip to the thick 1.5-2mm of the knife back to Roound edge corresponding position of 4mm The end of knife is handle of a knife.

Using the thin bamboo strip knife in above technical scheme rive a reed when, point of a knife alignment reed butt center penetrate and split Reed wall side is opened, is rived always to reed from root of phragmites communis slightly, after a reed stitched of riving is rolled softness with stone roller, compiled When knitting, a reed thin bamboo strip of upper and lower doubling is flattened into a piece of reed thin bamboo strip can be woven, because of a piece of reed being split into the thin bamboo strip knife The width of the reed thin bamboo strip is equal to the girth of reed, that is to say, that be twice that existing thin bamboo strip knife is split into two panels reed thin bamboo strip width, so with one Piece reed thin bamboo strip braid efficiency can be doubled.Because the stage casing of the thin bamboo strip knife is vertial knife edge, so can still rive two with the thin bamboo strip knife The piece reed thin bamboo strip.The reed of 6 thinner -8mm of diameter can be split into a piece of width with the thin bamboo strip knife is used for equal to the reed thin bamboo strip of girth Braiding, so be the utilization rate that improve resource with the thin bamboo strip knife, so as to reduce the waste of resource.
