Description
Technical field
This utility model relates to agricultural machinery technological field, particularly relates to a kind of bionical rotary blade.
Background technology
Tiller is mainly used in paddy field, the rotary tillage in nonirrigated farmland, hack etc., and small-sized, Miniature cultivator used on higher uses wide in Hills
General, rotary blade is the important ingredient on tiller.But existing tiller is in operation process, weeds often occur
Phenomenon with root stubble is wrapped in Rotary tillage blade, reduces the work efficiency of tiller.The most small-sized, the output of Miniature cultivator used on higher
Horsepower and power are little, once occur that weeds and root stubble are wrapped on Rotary tillage blade, will be stuck, and serious meeting causes electromotor
Burn out.So Rotary tillage blade is proposed requirements at the higher level.
Utility model content
This utility model aims to provide a kind of bionical rotary blade, well solves the problems referred to above, simple in construction, has and go out
Stubble function, cutting power is strong, and work efficiency is high.
The technical solution of the utility model is a kind of bionical rotary blade, and including blade, described blade rear end is provided with handle of a knife,
Described blade front end is bent to form blade section, and described blade section outer arc limit is provided with multiple bionical tooth, and bionical tooth includes parabolic
Line flank profil, bionical tooth crest is plane.
Further, the spacing of described bionical between cog is 5mm.
Further, described adjacent bionical between cog smooth arc transition.
Further, described bionical tooth has 13.
Further, the angle that described blade is intersegmental with blade is 60 ± 2 °.
Further, described handle of a knife is provided with installing hole.
The beneficial effects of the utility model are: this utility model is according to engineering bionic principle, by the dentation shape of Gryllotalpa mouthpart
State is applied to blade design, and the mouthpart of Gryllotalpa is strong effectively, can sting the seed and plant roots and stems sowed in geophagy earth.Gryllotalpa mouth
Dentalation in device contributes to it to cut off and crashing food, provides for having the structure design of the Rotary tillage blade of stubble cleaning functions concurrently
Bionics foundation.Using the bionical tooth design of Gryllotalpa mouthpart in blade section of the present utility model, beneficially rotary blade is in soil
Weeds and root stubble cut, stir disconnected, prevent it to be wrapped on rotary blade, it is to avoid tiller stuck, improve work
Efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is structure for amplifying schematic diagram at A in Fig. 1；
Fig. 3 is that the bionical rotary blade of this utility model is arranged on the structural representation on rotary tillage rotor
In figure: 1. handle of a knife, 2. blade, 3. blade section, 31. bionical teeth, 311. flank profils, 4. installing hole.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, to this reality
It is further elaborated with novel.
As shown in Figure 1, 2, this utility model provides a kind of bionical rotary blade, according to engineering bionic principle, by Gryllotalpa mouth
The dentation form of device is applied to blade design, and including blade 2, blade 2 rear end is provided with handle of a knife 1, and blade 2 front end is bent to form cutter
Sword section 3, blade section 3 outer arc limit is provided with multiple bionical tooth 31, and bionical tooth 31 includes that parabolic tooth-shape 311, bionical tooth 31 push up
Portion is plane.Bionical tooth 31 is roughly the same with the dentalation outline curve in Gryllotalpa mouthpart.The parabola tooth of bionical tooth 31
Wide 311 are arranged along bionical tooth 31 centrosymmetry, and bionical tooth 31 has dissection to weeds and root stubble, prevents weeds and root simultaneously
Stubble was wrapped on rotary blade in the same time, reduces rotary blade cutting weeds and the power of root stubble, reduce further tiller
Shaft horsepower and the use of power, saved the energy, top, epirelief parabolic tooth limit 311 is plane, equally to weeds and
Rhizome cuts, it is to avoid the situation that the tooth on pinnacle can only be cut by tooth limit, can preferably disperse weeds and rhizome, it is to avoid
It is simultaneously wound on rotary blade, causes the rotary blade load to increase.Spacing between bionical tooth 31 is 5mm, adjacent bionical tooth 31
Between smooth arc transition, bionical tooth 31 has 13.Angle between blade 2 and blade section 3 is 60 ± 2 °, can be well by rotary blade
Blade section is inserted in soil, and soil carries out rotary tillage, and rotary blade blade section 3 has certain angle, more with weeds and rhizome simultaneously
Easily it is cut, blade 2 and the angle of blade section 3 and the matching design of bionical tooth in blade section 3, make rotary blade insert
The angle of the angle of soil and cutting weeds has obtained best guarantee so that it is more laborsaving and convenient.It is provided with peace on handle of a knife 1
Dress hole 4, is conveniently installed to rotary blade on rotary tillage rotor, easy installation and removal.
Concrete, adjacent bionical tooth 31 spacing 5mm of blade section 3, single bionical tooth 31 is placed in cross coordinate system, bionical
Tooth 31 profile is: in the range of [0,1.63] coordinate a little meet parabola y=-(x-2.5) 2+6.25,
In the range of [1.63,3.37] coordinate a little meet straight line y=5.46, in the range of [3.37,5] coordinate a little
Meet parabola y=-(x-2.5) 2+6.25.
During use, bionical rotary blade is installed on bionical cutter rotor uniformly through installing hole, easy installation and removal,
Weeds in soil and root stubble are cut by the bionical tooth 31 on rotary blade, stir disconnected, prevent it to be wrapped on rotary blade, it is to avoid
Tiller stuck, improves work efficiency.
Certainly, this utility model also can have other various embodiments, spiritual and essence without departing substantially from this utility model
In the case of, those of ordinary skill in the art can make various corresponding change and deformation according to this utility model, but these phases
Change and the deformation answered all should belong to the scope of the claims appended by this utility model.
