Abstract
The utility model belongs to agricultural or forestry machinery field, is related to a kind of pawl toe Bionic conflguration tapping knife, is made of blade, tool arm and handle, obtains Heveatex for cutting rubber bark.Rubber tapping blade part is imitated muroid pawl toe form and is made, and is specifically alternately arranged and is formed by blade toe arc and blade toe point, and keeps a blade angle symmetrical along tapping knife center line, and blade angle is between 90 ° ~ 120 °；Tapping knife tool arm and blade are made of same metal material, and rigidly fix connection；Tapping knife handle is made of wood materials, and is threadedly coupled with tool arm.The utility model has the characteristics that structure is simple, easy to use and reliable, and secant quality can be improved, and extends tapping knife service life, compensates for deficiency existing for traditional tapping knife, has certain market application demand.
Description
Technical field
The utility model belongs to agricultural or forestry machinery field, harvests for natural rubber natural gum cream, more particularly to a kind of
Pawl toe Bionic conflguration tapping knife.
Background technique
Natural rubber elasticity with higher at normal temperature, slightly band plasticity, have extraordinary mechanical strength, be it is military and
The civilian important basic means of production.Heveatex mostlys come from bark duct cell, is to cut rubber by machine tool
What gum latex dust obtained, mechanical superiority and inferiority of tapping rubber directly affects Rubber Yield.
Presently the most common rubber tapping tool is exactly V-type twolip hand-held tapping knife, and this tapping knife is cheap, maintenance
With it is easy to carry, but when in use there is also blade easily it is blunt, secant is uneven the problems such as, need often to cutter head carry out polishing or
Replacement.Therefore a kind of sharp durable tapping knife is designed, to improve secant quality, extending tapping knife service life has certain city
Field value.
After bionics Study shows that many animal through a long times are evolved in nature, excavated with very perfect soil
With stripper for hard nut official, the geometry optimized and excellent mechanical property have been gradually formed, has made it in process of excavating and search for food
In can obtain larger cutting force, and do not damage oneself, break ground territory face if muroid pawl toe can easily be dug and peel off nut shells,
Its pawl toe outer rim shows as curved edge structure, and has certain malleable, since blade cuts bark process and muroid excavation
Soil and peel off nut there is similarity, thus the utility model with muroid pawl toe for bionical prototype, design a kind of bionical cut
Glue knife.
Summary of the invention
The purpose of this utility model is in order to improve secant quality and improve service life, with muroid pawl toe for bionical original
Type designs a kind of bionical tapping knife.The utility model can be achieved through the following technical solutions:
A kind of pawl toe Bionic conflguration tapping knife, the tapping knife are made of blade (1), tool arm (2) and handle (3)；It is described
Blade (1) is in muroid pawl toe form, is alternately arranged and is formed by blade toe arc (4) and blade toe sharp (5), and along tapping knife center line
Keep a blade angle α symmetrical, blade angle α is between 90 ° ~ 120 °；The tool arm (2) and blade (1) are by same metal
Material is made, and rigidly fixes connection；The handle (3) is made of wood materials, and is threadedly coupled with tool arm (2).
Blade (1) the pawl toe morphosis is equally applicable to electric cutter for rubber tapping, automatic rubber tapping machine and rubber tapping robot etc.
In the cutting blade of mechanical device.
The utility model has an advantageous effect in that, imitates the muroid pawl that can easily dig break ground territory face and stripping nut shells
Toe form Design tapping knife has structure simple, and processing is convenient, the chip ability of tapping knife can be improved, while extension makes
With the service life, improve secant quality, improves rubber tapping efficiency.
Detailed description of the invention:
Fig. 1 is pawl toe Bionic conflguration tapping knife overall structure diagram；
Fig. 2 is bionical tapping knife edging structure schematic diagram.
Wherein: 1. blades；2. tool arm；3. handle；4. blade toe arc；5. blade toe point；α blade angle.
Specific embodiment:
The specific structure and the course of work of the utility model are further described below in conjunction with attached drawing and embodiment.
Attached a kind of pawl toe Bionic conflguration tapping knife shown in FIG. 1, mainly by by blade (1), tool arm (2) and handle (3) group
At；Tool arm (2) is made with blade (1) of same metal material, and rigidly fixes connection；Handle (3) is made of wood materials, and
It is threadedly coupled with tool arm (2).
Attached bionical rubber tapping blade part (1) structure shown in Fig. 2, rubber tapping chip portion is in muroid pawl toe form, by blade toe
Arc (4) and blade toe sharp (5) are alternately arranged composition, and keep a blade angle α symmetrical along tapping knife center line, blade angle
α is between 90 ° ~ 120 °.
Bionical tapping knife shown in attached Fig. 1 and 2 is a kind of hand-held tapping knife, but attached bionical rubber tapping blade shown in Fig. 2
Portion (1) pawl toe morphosis is equally applicable to the cutting of the mechanical devices such as electric cutter for rubber tapping, automatic rubber tapping machine and rubber tapping robot
In blade.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.
