Operation in the operating environment of stalk stubble and radical operators.Bionics is an emerging cross discipline, bionic design method
The features such as high, adaptable with its design efficiency, become mechanical part optimization design and improved effective way.With bionics
Design method designs novel cutaway disk plough, improves it in the operating environment with crop straw stubble and radical operators
Operation quality and service life, the development of research and development and conservation tillage to plough all have highly important theory significance and
Realistic meaning.
Naked mole, is the soil animal for excavating organ with tooth, and incisor has the geometry optimized and excellent power
Performance is learned, in excavating soil and feeding process, incisor buries, and broken soil performance is excellent, and suffered Cutting Drag is low, cuts soil
High-efficient with plant roots and stems, wearability is good；Bullhead shark, in shark family figure be only second to great white shark ferociousness it is cruel food meat it is dynamic
Object, predation shellfish, shell-fish and fish, its tooth can be bitten broken, grind very hard object, have the geometry knot of optimization
Structure.Intelligent electric-controlled technology, is widely used in mechanical equipment, automatically controls mechanical equipment, actively completes task, greatly
Improve the working efficiency of mechanical equipment.Therefore the structure that naked mole and bullhead shark tooth are applied to cutaway disk plough is set
Meter, and intelligent electric-controlled technology is combined, the geometry and mechanical property of cutaway disk plough are optimized, a kind of reality is designed
When controllable type double-layer bionic cutaway disk plough.
