    摘要:

    設(shè)計(jì)了一種內(nèi)置式雙位投種穴播器，在牽引工作狀態(tài)下自動(dòng)滾動(dòng)、實(shí)現(xiàn)入土成穴器入土。采用內(nèi)置式雙位投種方式，且上位一次變量排種器布置在輪盤的定盤中心，以減小向入土成穴器的輸種距離和省略傳動(dòng)裝置。入土成穴器采用定、動(dòng)兩瓣結(jié)構(gòu)，非開啟狀態(tài)為常閉，動(dòng)瓣在達(dá)到最大入土深度后按杠桿原理打開，完成下位二次投種、出土后關(guān)閉。樣機(jī)試驗(yàn)證明，穴播器各項(xiàng)性能符合設(shè)計(jì)和農(nóng)藝要求。

    Abstract:

    A dibbler with embedded doubleposition throwing seeds was presented. Variable seedmetering device on the position was layout in the center of helmshaped wheel for shortening the distance of dropping seeds and omitting gearing device. Boring and caving device was composed with fixed part and rotatable part, always closed in the state of non-opening. Based on the lever principle, rotatable part was opened when the most depth in the soil was reached. The second lower position throwing seeds was completed, and then rotatable part was came up out of soil and closed. The experiment results showed that the proposed dibbler could meet the design and agriculture requirements. 
