Description
Technical field
This utility model is related to agricultural mechanical field and in particular to a kind of ditching knife assembly.
Background technology
Ditching knife is to carry out ditching in agricultural production digging the critical piece of canal operation, and current canal operation of digging is to ditch
Piece is arranged in the drive shaft of the agricultural machinery such as tiller both sides, drives trench digging wheel rotation to dig the mesh of canal to realize ditching by drive shaft
, and the blade on the ditching knife adopting at present is all slice structure, is all hard contact during the hard thing of blade contact, easily to knife
Piece causes damage, and breach and crackle easily, or even fracture.
Chinese Patent Application No. discloses a kind of ditching knife disc assembly for 201320832947.X, including rotary tillage shaft and trench digging
Axle, trench digging axle is fixed on the centre of rotary tillage shaft, is fixed with Rotary tillage blade and cliff blade on rotary tillage shaft, fixing on trench digging axle
There is furrow-opening cutter blade, furrow-opening cutter blade is right for three, adjacent two to diametrically differing 60 ° of arrangements, and Rotary tillage blade and cliff blade are in rotation
The arrangement that is staggered in 90 ° on the circumference of cultivated axle, in two symmetrical Rotary tillage blades of same location arrangements of rotary tillage shaft axial direction.Should
Ditching knife be three to and be evenly arranged in trench digging axle circumference on, thus the consistent of ditching depth is realized with less ditching knife
Property.Rotary tillage blade and 90 ° of cliff blade are staggered arrangement, make the moment of torsion that rotary blade is subject to more reasonable, rotary tillage cutter shaft is difficult to become
Shape.But it does not still solve the problems, such as hard contact, blade is easily damaged, and maintenance cost is high.
Utility model content
The purpose of this utility model is to provide a kind of ditching knife assembly, above-mentioned multinomial with solve to lead in prior art
Defect.
A kind of ditching knife assembly, including cutterhead, blade, localizer and rotating shaft, described cutterhead is fixed in rotating shaft, described fixed
One end of position device is connected by a pair of bolts with cutterhead, and the other end of localizer is provided with installation portion, and the top of installation portion is provided with out
Mouthful, the side of installation portion is provided with locating shaft, and the bottom of described blade is rotatably connected on locating shaft and by lid by blade card
Live, locating shaft is additionally provided with torsion spring, blade is linked together with installation portion.
Preferably, the quantity of described localizer is 8-12, and radially arranges.
Preferably, described cutterhead is provided with some through holes, and radially arranges.

Specific embodiment
Technological means, creation characteristic, reached purpose and effect for making this utility model realize are easy to understand, below
In conjunction with specific embodiment, this utility model is expanded on further.
As shown in Figures 1 to 4, a kind of ditching knife assembly, including cutterhead 1, blade 2, localizer 3 and rotating shaft 4, described cutterhead
1 is fixed in rotating shaft 4, and one end of described localizer 3 is connected by a pair of bolts 5 with cutterhead 1, and the other end of localizer 3 is provided with
Installation portion 6, the top of installation portion 6 is provided with opening 7, and the side of installation portion 6 is provided with locating shaft, and the bottom of described blade 2 rotates even
It is connected on locating shaft and by lid 8, blade 2 is blocked, locating shaft is additionally provided with torsion spring 9, blade 2 is connected to installation portion 6
Together.Blade 2 extends to outside localizer 3 through opening 7, and in original state, blade 2 is tight under the elastic force effect of torsion spring 9
Against the side of opening 7, after contacting hard thing, blade 2 rotates backward under powerful external force effect, plays certain buffering and makees
With reducing and firmly contacting the damage that blade 2 is caused, postpone the service life of blade 2, generally, the torsion of torsion spring 9 is enough
Greatly, blade 2 typically will not turn to another side contacts with opening 7 immediately rearward.
It should be noted that the quantity of described localizer 3 is 8-12, and radially arrange.
In the present embodiment, described cutterhead 1 is provided with some through holes 10, and radially arranges, and can mitigate the weight of cutterhead 1
Amount, reduces oil consumption.
In the present embodiment, the outside of described localizer 3 is provided with one section of chamfering 11, by the chamfering 11 of setting, can subtract
The little resistance that localizer 3 causes to soil in trench digging, improves trench digging efficiency.
Additionally, being additionally provided with some reinforcements 12 on described cutterhead 1, improve the strength and stiffness of whole device.
Based on above-mentioned, this utility model existing ditching knife structure of improvement, the localizer 3 of design makes blade 2 in contact
There is a buffering surplus during to hard thing, the hard contact of blade 2 and hard thing can be avoided, reduce the impaired probability of blade 2, extend
The service life of blade 2.
As known by the technical knowledge, this utility model can be by the reality of other essence without departing from its spirit or essential feature
Apply scheme to realize.Therefore, embodiment disclosed above, for each side, is all merely illustrative, and is not only
's.All in the range of this utility model or be equal to the change in the range of this utility model all by this utility model bag
Contain.
