dead sure

Design method of farm machine products drop behind the one of manufactured products . to make our country ' s design and manufacturing technology of dead stock to achieve the standard of developed country , to develop parallel with other machine manufacture , this article introduce cad , optimization design , computer simulation technique into the design of the ditcher , to make its design more reasonable , much higher quality to bring social benefit , economic benefit , ecological significance 我國農業機械產品的設計方法相對工業產品來說比較落后,為了使我國農機設計制造技術達到發達國家水平,與其它機械制造業平行發展,本文將計算機輔助設計、優化設計、計算機模擬技術引用到該機具的設計中,使該機具的設計更合理、更高質,使它盡快地產生社會效益、經濟效益、生態效益。

Reasonable structure , can be folded , convenient to carry . if as for dead stock , it ' s not practical , and expensive , so it ' s not 結構緊湊,合理,可折疊,方便攜帶。作為農具的實用價質太低,而造價太高,不是農具。
