Description
Technical field
The utility model relates to agricultural machinery technological field, is specifically related to a kind of Novel disc rotary-cut
Ditching knife.
Background technology
Existing no-tillage seeding machine trench digging generally employing rotary blade, but the hack ability of rotary blade
Difference, is easily wound around weeds, and area of breaking ground is big, consumes power many, makes no-tillage seeding machine is actual
Cause stalk and soil mixing in, make seed implantation bad.
Patent No. 201220208974.5 discloses and protects a kind of cultivating free seeder
Disk guillotine cutting ditching knife, its blade is arranged on a side of blade, deposits in actual use
In following 2 deficiencies: one is that edge wear is very fast, and replacement frequency is higher, affects operating efficiency,
Increasing use cost, two is not to be suitable for multiple soil working, straw impact cutting poor effect.
Content of the invention
The purpose of this utility model is to solve the deficiency that above-mentioned prior art exists, and provides one
Novel disc rotary-cut ditching knife, simple and reasonable, edge wear is slow, uses the time long, can
Being applicable to multiple soil working, straw impact cutting effect is good.
The technical solution adopted in the utility model is: a kind of Novel disc rotary-cut ditching knife, including
Installing disk 1 and cutter hub 2, cutter hub 2 is evenly provided on installation disk 1, and by tightly
Fixing bolt is fixed, and described cutter hub 2 is made up of handle of a knife the 21st, blade 22 and blade 23, cutter
Sword 23 is arranged on the periphery of blade 22, has included angle A, A between handle of a knife 21 and blade 22
Numerical value be between 90 °～180 °.
In order to be applicable to multiple soil working and preferably impact cutting straw, described blade 23 is
Curve-like.
Described blade 23 is preferably bicircular arcs one linearity.
Described blade 23 is preferably two straight line one arc-shapeds.
The utility model has the advantages that simple in construction is closed compared with prior art
Reason, blade is arranged on the periphery of blade, after abrasion, can integrally exchange use, extends
The use time of cutter, curvilinear blade is applicable to multiple soil working, straw impact cutting effect
Good.
Brief description
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the left view of Fig. 1,
Fig. 3 is bicircular arcs of the present utility model wire cutter hub schematic diagram always,
Fig. 4 is two straight line one arc-shaped cutter hub schematic diagrames of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that this
The advantages and features of utility model can be easier to be readily appreciated by one skilled in the art, thus to this reality
Made by novel protection domain and apparent clearly defining.
A kind of Novel disc rotary-cut ditching knife as depicted in figs. 1 and 2, including install disk 1
With cutter hub 2, cutter hub 2 is evenly provided on installation disk 1, and is fixed by fastening bolt,
Described cutter hub 2 is made up of handle of a knife the 21st, blade 22 and blade 23, and blade 23 is arranged on cutter
On the periphery of body 22, having included angle A between handle of a knife 21 and blade 22, the numerical value of A is 135 °.
The blade of cutter hub as shown in Figure 3 is bicircular arcs one linearity, by the circular arc of two R80
With straight line composition, the blade of cutter hub as shown in Figure 4 is two straight line one arc-shapeds, by two
The circular arc composition of bar straight line and a R16, this by the curve-like blade of circular arc and rectilinear(-al)
The effect capturing impact cutting straw can be played when operation, improve straw impact cutting effect.
Disk rotary is cut ditching knife and is arranged on the cutter shaft of no-tillage seeding machine, and rotates around cutter shaft,
Carrying out shredding to soil, carrying out impact cutting to straw, in operation process, the blade of working face can grind
Damaging, affecting operation effectiveness, at this moment integral-rotation is exchanged disk rotary and is cut ditching knife, uses another
The blade in face carries out operation, improves the service efficiency of cutter, extends the use time of cutter.
It is not limited to this, any change expected without creative work or replacement, all should contain
Cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should
It is as the criterion with the protection domain that claims are limited.
