    摘要:

    論述了一種免耕播種防堵裝置——仿形爪式清茬機(jī)構(gòu)的工作原理，推導(dǎo)了輪爪上任一頂點(diǎn)的運(yùn)動(dòng)軌跡、速度和加速度方程并給出了相應(yīng)計(jì)算機(jī)繪圖，分析了該機(jī)構(gòu)的參數(shù)對工作性能的影響。結(jié)果表明：運(yùn)動(dòng)偏角δ宜在20°～40°之間選取，運(yùn)動(dòng)偏角δ比爪輪半徑R對清茬機(jī)構(gòu)工作幅寬影響大，輪爪宜采用后傾的布置形式。

    Abstract:

    Work principle of a new anti-blocking mechanism for no-till planting was described. Equations about the trajectory, the absolute velocity and the acceleration of any vertex on the finger wheel were deduced. Associated graphics were constructed by software, and parameters of the device were analyzed. The results indicated that the movement angles δ was chosen between 20°～40°and had great influence on working width compared with radius of the finger wheel. Backward inclined distribution should be adopted for the finger. 
