Description
Technical field
The present invention relates to stem cutting knife.It is more particularly related to a kind of rate of cutting is fast, cutting efficiency is high,
Utilization rate stem cutting knife high.
Background technology
At present, the cutter mostly circular configuration for being cut to the plant for having stalk, the shape of its cutting zone has two
Kind, a kind of to be shaped as being uniformly arranged multiple sawtooth in the excircle of cutter, another kind is shaped as in the cylindrical of round cutter
Multiple blades are uniformly arranged on week, it is all that stalk is cut off by the blade or the revolving force of sawtooth on cutterhead, both knots
Structure has the defect that cutting speed is slow, cutting efficiency is low, if the one of breaks down of round cutter or part are sawed
Tooth is damaged, and can have a strong impact on cutting effect.In cutting process, because the cutting speed of round cutter is slow, it is possible that
More than the cutting speed of cutter, this necessarily causes stalk to be cut knife cut-out to the gait of march of machine, and directly by machine
Device is pushed over or uprooped.Simultaneously in cutting process, because topographic features are changeable, therefore can influence to cut to a certain extent
Cut efficiency.
In view of more than, it would be highly desirable to there is a kind of generation of the stem cutting knife that cutting speed is fast, cutting efficiency is high, utilization rate is high.
The content of the invention
The present invention is regarding to the issue above, there is provided a kind of cutting speed is fast, cutting efficiency is high and the good stem of using effect

Brief description of the drawings
Fig. 1 is the schematic diagram of stem cutting knife in one of embodiment of the invention.
Fig. 2 is the schematic diagram of cambered blade of the invention.
Fig. 3 is the schematic diagram of stem cutting knife in an alternative embodiment of the invention.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to specification text
Word can be implemented according to this.
Fig. 1 shows a kind of stem cutting knife of the invention, and it is that the cutting part for using plane tabular is used for relatively
The cutter being installed on pivot pivotal axis of the cut-out plant haulm of rotation, including：
Cutting part 1, its middle part and pivotal axis pivot joint, the cutting part are also included with pivotal axis as the center of circle extends outward
At least two lamellar cutters 110, the cutting member periphery is arc, and an edge part for the arc sets multiple continuous
Sawtooth 120, the maximum of the edge of at least two lamellar cutter apart from the pivotal axis center of circle is 240~280mm；
Wherein, on the direction of rotation along stem cutting knife, the first half of the periphery of the cutter is without sawtooth
Buffer part, the latter half of the periphery of the cutter is the blade part with continuous sawtooth.Shape between two neighboring cutting member 110
Into a cutting domain, stem cutting knife is gradually eaten the stalk of plant along edge arc direction until will in rotation process
Stalk is cut off, and its cutting process cuts in domain at one and can just complete, because the velocity of rotation of cutter is exceedingly fast, therefore cutting speed
Degree is more many soon than the gait of march of machine, even if machine travel is unstable, what cutter can also be exceedingly fast cuts the stalk of plant
It is disconnected, it is to avoid the gait of march due to cutting speed less than machine, cause the machine to push over plant haulm and cutting can not be completed
Defect.
Another implementation that above-mentioned cutting part completes cutting is：
Through hole 130, the blade part inner side that it is arranged on the cutting member；
Multiple arcs blade 2, the lamellar body of the cambered blade 2 is provided with mounting hole 210, bolt through the mounting hole and
The through hole, the cambered blade 2 is fixedly connected with the cutting part 1, and the knife-edge leading end of the cambered blade is located at institute
State between the front end and rear end of blade part sawtooth, to cause that the cambered blade 2 and the sawtooth 120 work simultaneously, due to peace
Dress hole 210 is overlapped with through hole 130, therefore mounting hole 210 is merely illustrated in Fig. 2.
In another embodiment, above-mentioned cambered blade 2 is with the implementation of the work simultaneously of sawtooth 120：The arc
The knife-edge leading end of blade be located at the sawtooth tooth it is high 1/4 at.Cambered blade can not only coordinate sawtooth while completing cutting operation,
Cutting task can be carried out in the case where damaging occurs in sawtooth instead of sawtooth, it is to avoid to be changed because sawtooth has damage simultaneously
The trouble of cutter, it is time saving and energy saving, also reduce cost.
In another embodiment, as shown in Fig. 2 on direction of rotation along stem cutting knife, the cambered blade 2 is anterior
The blade 220 for dividing is zigzag, and the blade 230 of part has inclined plane after the cambered blade.
In another embodiment, as shown in figures 1 and 3, the stem cutting knife also includes：Fixed part 3, it includes knife
Disk 310 and retainer plate 320, the cutterhead 310 are arranged on the pivotal axis with cutting part side contact position, the retainer plate
320 are arranged on the cutting part opposite side, to cause to grip the cutting part between the cutterhead 310 and retainer plate 320.
In another embodiment, in order to preferably complete cutting operation：The edge of at least two lamellar cutters 110 away from
The difference of the minimum value in the pivotal axis center of circle is 50~80mm with a distance from the maximum and its edge in the pivotal axis center of circle.
In another embodiment, in order to preferably complete cutting operation：The edge distance of at least two lamellar cutters
The maximum in the pivotal axis center of circle and its edge are optimized for 70mm apart from the difference of the minimum value in the pivotal axis center of circle.
In another embodiment, minimum value of the edge of at least two lamellar cutters apart from the pivotal axis center of circle is 150
~180mm.
In another embodiment, maximum of the edge of at least two lamellar cutters apart from the pivotal axis center of circle is
250mm。
In another embodiment, minimum value of the edge of at least two lamellar cutters apart from the pivotal axis center of circle is
166mm。
Although embodiment of the present invention is disclosed as above, it is not restricted to listed in specification and implementation method
With.It can be applied to various suitable the field of the invention completely.For those skilled in the art, can be easily
Realize other modification.Therefore under the universal limited without departing substantially from claim and equivalency range, the present invention is not limited
In specific details and shown here as the legend with description.
