Cambered top end is equipped with cutting edge.
A kind of bionical rotary blade suitable for clayed soil operation, it is characterised in that：The section of the bionical pit of circle
Profile is semicircular arc-shaped.
A kind of bionical rotary blade suitable for clayed soil operation, it is characterised in that：The bionical pit profile of circle
Spherical for semicircle, arc radius 2-3mm, hole width is 4-6mm, and hole depth is 1.5-2.5mm.
A kind of bionical rotary blade suitable for clayed soil operation, it is characterised in that：The pit is on blade surface edge
Blade trend is uniformly distributed, and every longitudinal direction pit centres line is parallel to each other, distance between longitudinal pit centres and pit centres
For 8-12mm.
A kind of bionical rotary blade suitable for clayed soil operation, it is characterised in that：The arc sliding cutting block welding is in knife
The side that connect with cutter shaft of seat, sliding cutting block radius are 245 ± 0.5mm, and the cambered top end of sliding cutting block is equipped with cutting edge, and sliding cutting block
The outer edge of circular arc and blade can be cut in straight line altogether.
The utility model provides a kind of bionical rotary blade suitable for clayed soil operation, has the advantages that：
The design of the utility model is applied to rotation according to bionics principle, by the dimple-shaped geometric non-smooth structure feature of dung beetle body surface
The optimization design of coulter blade.Soil animal dung beetle passes through natural selection, and body surface evolves dimple-shaped geometric non-smooth structure, this
Kind dimple-shaped structure can store a small amount of air, avoid forming vacuum environment between soil and body surface, so that dung beetle be made to live in the soil
Keep body surface substantially without soil when dynamic, it is clear that this dimple-shaped geometric non-smooth structure has the function of excellent reducing adhesion resistance.In knife
Bionical pit is equably set on the two sides of body, and this rotary blade when operation, is avoided that between blade and soil in clayed soil
Vacuum environment is formed, adherency of the soil to blade is reduced, reduces the resistance that blade buries, this rotary blade is made to reduce extra bear
More laborsaving convenience, reduces operation consumption after lotus, improves work efficiency.Blade surface alleviates knife after digging out pit simultaneously
The weight of piece equally reduces the load that motor drives rotor rotation, realizes energy-saving purpose.Furthermore geometric non-smooth
Dimple-shaped there is certain wearability, this configuration reduces the abrasion that rotary blade is contacted with soil, be beneficial to extension blade
Service life keeps rotary blade more durable, has saved the cost of rotary blade maintenance and replacement.It is sliding that tool apron connects side welding one with cutter shaft
Stripping and slicing, sliding cutting block is arc-shaped, and cambered top end is equipped with cutting edge, and when stalk touches sliding cutting block, the cutting edge of sliding cutting block can be to stalk
It carries out sliding cutting and throws away, effectively stalk can be avoided to be wrapped on cutter shaft, to prevent the stuck of rotary cultivator from burning out.
Detailed description of the invention：
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is sliding cutting block schematic diagram；
Fig. 3 is the partial cutaway view of bionical pit.
Fig. 1, in 2：1- cutter shaft, 2- tool apron, 3- mounting hole, 4- sliding cutting block, 41- sliding cutting sword, 5- blade, 51- are bionical recessed
Hole, 511- pit profile, 6- blade
Specific embodiment：
To keep the utility model clearer, 1-3 does the utility model and further elaborates with reference to the accompanying drawing.
As shown in Figure 1, 2, a kind of bionical rotary blade suitable for clayed soil operation, including cutter shaft 1, tool apron 2, mounting hole
3, sliding cutting block 4, blade 5, and blade 6 on the outside of blade are set to, the knife handle insertion of the rotary blade is mounted in tool apron 2, and
It is fastened using bolt and nut by mounting hole 3, the other end of tool apron is weldingly fixed on rotary knife axis 1.The sliding cutting block 4
It is welded on the side that tool apron is connected with cutter shaft, the cambered top end of sliding cutting block is equipped with cutting edge, when stalk touches sliding cutting block, sliding cutting
The cutting edge of block can carry out sliding cutting and be thrown away to stalk, effectively stalk can be avoided to be wrapped on cutter shaft, to prevent the card of rotary cultivator
Dead roasting is bad.
As shown in Figure 1,3, the circular bionical pit 51 of the 5 surface uniform design of blade, the bionical pit be by
According to bionics principle, the dimple-shaped geometric non-smooth structure feature of the body surface of dung beetle is optimized.Dung beetle is in soil
But the advantage of the non-sticky soil of body is closely connected with the dimple-shaped geometric non-smooth structure of its body surface for activity, so by this dimple-shaped
Geometric non-smooth structure feature is optimized to the design of pit 51 on the blade 5 of rotary blade, and this rotary blade can be made in cohesive soil
It in earth when operation, prevents soil and blade surface from forming vacuum environment, reduces the adherency of soil, reduce blade soil-entering resistance, drop
Low operation power consumption improves operation quality.After outputing bionical pit 51 on blade 5 simultaneously, blade own wt is alleviated, together
Sample also reduces the operation consumption of rotary cultivator.Furthermore bionical pit has certain wearability, reduces abrasion of the soil to blade,
In the service life for extending blade, the cost of running maintenance and more allowing blade replacement is saved.
As shown in Fig. 2, the bionical pit profile is that semicircle is spherical, arc radius 2-3mm, hole width is 4-6mm, and hole is deep
For 1.5-2.5mm.
As shown in Figure 1, the bionical pit is uniformly distributed on blade surface along blade trend, every longitudinal direction pit centres line
It is parallel to each other, distance is 8-12mm between longitudinal pit centres and pit centres.
As shown in Figure 1, the arc sliding cutting block welding, in the side that tool apron is connected with cutter shaft, arc sliding cutting block radius is
The cambered top end of 245 ± 0.5mm, sliding cutting block are equipped with cutting edge, and the outer edge of the circular arc of sliding cutting block and blade can be cut in one altogether
Straight line.
Example discussed above is only that the preferred embodiment of the utility model is described, not practical new to this
The range of type is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this reality
Various changes and improvements are made with novel technical solution, should belong to the utility model the attached claims protection scope.
