The problems such as power is big, and soil adhesion is serious and power consumption is big, therefore the appropriate design of rotary cultivator rotor is effectively to solve problem above
Important channel.
Mole is a kind of soil burrowing animal be good at and excavating, and its humerus, ulna and radius and the forelimb pawl palm are moles
The important excavation organ of Mus.Being observed by actual experiment and measure, mole humerus longitudinal section is oval, the oval length in its China and foreign countries
Semiaxis a and b meets b/a=0.33-0.42；Forearm is the shortest and the smallest, a length of 4.82-6.24mm, and its short and small structure can meet
Activity in small space, and reduce soil cutting resistance；The forelimb pawl palm is flat roomy, and length is 3-5 times of forearm, before width
2.5-4 times of arm lengths, can be effectively improved and cut soil efficiency；Forelimb pawl toe back side longitudinal direction characteristic curve is logatithmic spiral, this curve
Rotary cutting resistance can be reduced, and stress distribution is uniform, improves bearing capacity.The collaborative work of these architectural features just
With, the excavation characteristic that mole is stronger could be realized, this is that the structure design that rotary cultivator rotor reducing adhesion consumes provides reference, can carry
High rotary cultivator work efficiency.
Summary of the invention
It is an object of the invention to design Novel rotary cultivator knife roller structure, meeting the cultivating quality condition that rotary cultivator is good
Under, reduce soil adhesion degree, improve working performance, and reduce operation power consumption.
The present invention is to be made up of cutter shaft, spindle nose, tool rest and rotary blade, and some tool rests are symmetrically welded on cutter shaft 1, on tool rest
Installing rotary blade, the rotary blade of side is right tilling blade, and the rotary blade of opposite side is left curved rotary blade, and the two ends of cutter shaft are installed
Spindle nose.
Cutter shaft is oval hollow axle, and oval major semiaxis a meets with oval semi-minor axis b: b/a=0.4～0.8, a=60～
120mm, the thickness d of oval hollow axle is 10～20mm.
The side cutting blade wrap angle of rotary bladeMAXBeing 10 °～25 °, the fabric width B of the Sidelong portion of rotary blade is 70～120mm, tangent
The back side in face is by characteristic curve DE:R (θ)=R0× exp (f × θ) scans and forms, wherein R0Being 185～240mm, f is 0.35
～-0.57, θ is 0～18 °, and rotary blade surface covers one layer of superhigh molecular weight polyethylene material, High molecular weight polyethylene material
Thickness is 0.3～0.5mm, and the blade of rotary blade uses T7 material.Blade is made to have surface not clay and the feature of edge wear.
Beneficial effects of the present invention:
Global design meets bionics principle, has the mining structure feature that mole is overall；Cutter shaft is oval hollow axle, no
Only there is the torsional rigidity of circular hollow tube, it is also possible to improve bending strength, reduce cutter shaft deformation and vibration, improve stability.
Operation power consumption can be reduced；Tool rest is symmetrically arranged amongst major axis two ends, and one end is right tilling blade, and the other end is left curved rotary blade, is subject to
Power is uniform；Side cutting blade cornerite is less, can effectively reduce moment of torsion；Sidelong portion fabric width is relatively big, and the back side is scanned by characteristic curve and formed,
Can be effectively improved and cut soil efficiency, reduce and cut soil resistance.Rotary blade surface covers one layer of superhigh molecular weight polyethylene material, and blade is adopted
Use T7 material, make blade have surface not clay and the feature of edge wear.Bearing capacity of the present invention is strong, and work efficiency is high, can
Reduce power consumption 14～22%.
Described rotary blade is to use that mole forearm is short and small and forelimb pawl is slapped flat roomy feature structure and designed, and can drop
Low rotary cutting soil resistance, reduces operation power consumption.
