机动小钳夹拔秧机的拔秧质量基本能满足农艺要求,是目前一种比较成熟的机型。但起拔秧苗时断秧仍是影响此机功效和性能进一步提高的一个主要因素。对影响断、伤秧的因素已做了一些试验、分析。从拔秧机考虑,认为影响断秧的因素主要是秧钳的扭转角(或扭转角速度)和起拔速度。并在这个前提下,对拔秧机作了轨道运动的初步理论分析。但这些因素与秧苗的内力如何联系,则没有
Maneuvering small clamp poplar seedling quality to meet the basic agronomic requirements, is currently a more mature models. However, the seedling cutting seedling is still affecting the machine efficiency and performance to further improve a major factor. The impact of broken, injury seedlings have done some experiments, analysis. Considered from the rice transplanter, the factors that affect the seedling seeding are the twisting angle (or twisting angular velocity) and the pulling speed of the seedling clamp. And under this premise, the preliminary theoretical analysis of the orbital movement was made. However, these factors and the internal forces of seedlings how to contact, no
