2、以及關鍵部件結構與工作參數(shù)設計等。該設備主要由挖掘鏟、振動篩、行走輪、動力傳動裝置及機架等組成。此機械設備工作順暢運行可靠，生產(chǎn)率：0.1～0.13hm2/h，莢果破碎率：1%，清土率高，損失率低,損失率：3%,，適用于個體較大規(guī)模的機械化生產(chǎn)，解放勞動力。關鍵詞：振動篩；平行連桿；挖掘鏟；帶輪23AbstractPeanutistraditionalplant,hasbecomeChina'simportantexportproductsandfocusonthedevelopmentofagriculturalrestructuringandsupportthecultiv
