This paper set up a dynamic model of soil range to be moved and develops a mathematical model of disccoulter force.
对圆盘开沟器扰动土壤的作用域进行了分析，建立了圆盘开沟器的受力模型。

The unique structure of smooth and depth disccoulter combined with horizontal disc cleaning residues for the mode is first researched in China.
为此，在国内首次研发了适合于这种模式的前限深圆盘破茬后水平圆盘清垄的独特结构。

The influence of disc dimension parameters, velocity, soil properties, tool surface properties on the disccoulter force were analysed by comparison with the experimental results.
