In this paper, based on the data from actual measurement, the equation of seedspout curve is obtained. The formula of seed moving velocity in the seed spout is also derived. Then the velocity VK at the discharge end of the seed spout and the horizontal component VKs of VK are calculated. The optimum sowing speed for thistype of seed spout has been verified, thus gives a reference to the seed spout design.

The mathematical model of PLPPU, which is used to control planting depth, is constructed. This model expresses the relationship between the planting depth and the parameters of PLPPU. The computer simulates this model.The results of the computer simulation show that the behaviours of PLPPU are influenced by parameters separately each to different extent. These parameters are interrelated and complexly affect the performance of PLPPU. The most obvious interrelation can be seen among planting speed, distance between contour wheels and openers, and opener types.

建立了用于控制开沟深度的精密播种单体仿形机构的数学模型,阐明仿形机构结构参数与开沟深度之间的关系,并用该模型进行了精密播种单体仿形机构的计算机仿真。结果表明,各结构参数均以不同方式影响仿形性能,更重要的是,不同参数组合时仿形性能不同,其中最明显的是播种速度、仿形轮与开沟器之间的距离及开沟器类型三者的不同组合。
