牧草切根机工作原理的分析

Analysis of the Operational Principle of Root-cutting Machine

分析了草场不同土壤条件对牧草生长和草场生态恢复的影响;研究了退化草场机械化破土切根技术和模式;探讨了高坚实度土壤条件的草场破土机理与根茎型或根茎疏丛型牧草横走根茎切根方式;开发了适用于高坚实度板结性退化草场的破土切根机。根据研发要求,应用力学和机械运动学等理论,着重对曲柄摇杆的运动以及直切刀的速度与受力进行分析,设计出结构简单、入土能力强和工作阻力小的直切式牧草切根机。

To analyze the influence of the different soil conditions on the grass growth and the ecosystem of grass recover, research the mechanization technique and modes of root - cutting, discuss the mechanism and cutting mode with high soil compactness, design the root - cutting machine applied to the high soil compactness. According to these requests, the author designs the direct cutter. This article＇ s analysis using the theory of theoretical mechanics and mechanical kinematics is focus on crank linkage motion, especially on the velocity and acceleration of the direct cutter. And the author designs the machine with simple structure, strong penetrating ability and little effective resistance.
