    摘要:

    設計了一種與手扶拖拉機配套的撥指輪式馬鈴薯挖掘機,。該機采用柵條式挖掘裝置和撥指輪式分離裝置,。對分離裝置進行了理論分析,，確定了其結(jié)構(gòu)參數(shù),。田間試驗表明：馬鈴薯挖掘機挖掘,、輸運順暢,，分離效果明顯,，傷薯率為4.5%,，損失率為3.6%,，明薯率為96.5%。

    Abstract:

    A certain potato digger in poke finger’s wheel type which fit walking tractor was designed. The machine used the fenselike digging device and the separation device in poke finger’s wheel type. The structure parameters of the device for separating potato and soil was determined based on theoretical analysis.Field experimental results showed that potato digger performed smoothly in digging, lifting and transporting without any block, and potatoes were separated effectively from soil. Damage rate was 4.5%, losing rate was 3.6%, and obvious rate was 96.5%.
