Description
Technical field
The present invention relates to a kind of using sand fish lizard as the Bionic wear-resisting sport of prototype, belongs to agriculture scarification equipment technology neck
Domain.
Background technique
Sport be mainly used for more sundries and chad soil and hack operation meadowy.Elastic claw bending is close arc-shaped,
Tip sharpening separately adds steel to uproot tooth.Rake teeth is made of bar-spring steel, is fixed on rotatable harrow frame crossbeam, by hand lever tune
The penetrating angle of elastic claw is saved to change depth of raking the soil level；When transport, rake teeth can be adjusted to leaving ground completely.Its work characteristics is:
It is pressed towards rear when any elastic claw meets obstructions biggish stone or grass roots using the elasticity of elastic claw, the bullet after resistance reduction
Tooth restores original position, and stone or grass roots is provoked, and soil block is smashed；If resistance is excessive, elastic claw curvature becomes
Greatly, it sets back, moves on after finally crossing obstruction.But sport is during provoking and smashing soil block, if resistance
It is excessive not only to will increase operation consumption, it even will lead to sport when serious and be difficult to reset；In addition, there is serious rub on rake teeth surface
Wear phenomenon, the especially abrasion of rake teeth tooth tip are wiped, leads to that hack is ineffective, rake teeth service life is insufficient.Therefore
Overcome advance resistance and frictional force is current main research direction.
Bionics Study shows, soil animal have the function of to adapt to the body structure of different soils environment and, pass through analysis
With the morphological feature and biological nature of simulation typical soil animal, Bionic Design is carried out to existing agricultural machinery soil-engaging component.
Sand fish lizard is a category very special in the lizard of desert, and main existence is in arid, semiarid desert edge area.Its it is special it
It is in can freely be fast moved such as swimming fish inside the sand dune of arid, therefore referred to as " sand fish lizard ".Sand fish lizard four limbs
Prosperity likes digging cave, when digging cave every time, first head nuzzled among sand dune, then front foot firmly, body bilateral swing, quickly
Inside agility drilling sand dune, however, since sand fish lizard body surface has excellent abrasive wear resistant weld deposit characteristic, in violent abrasion environment
Under, body surface can remain intact.Therefore the invention patent devises a kind of using sand fish lizard as the Bionic wear-resisting sport of prototype.
Summary of the invention
The technical problem to be solved by the present invention is the present invention provide it is a kind of using sand fish lizard as the Bionic wear-resisting elastic claw of prototype
Rake, for solving the problems, such as that excessively high advance resistance that existing sport encounters during the work time and abrasive wear are serious.
The technical scheme is that: it is a kind of using sand fish lizard as the Bionic wear-resisting sport of prototype, including rack 1 and sport
