甘蔗种植机设计中两个问题的探讨

本文探讨了甘蔗种植机设计中两个重要参数的确定原则和计算方法。目前沿用的计算方法没有考虑橡胶管弹性变形后滚筒的有效作用半径要受蔗径影响这一因素，导致计算结果不够精确，对此作者提出了新的计算公式，成功地设计了配装在东方红－７５拖拉机上、具有大容量种蔗箱的ＺＣＺ２－９２型甘蔗种植机，而且对由于行走与排种不同步造成的实际误差也完全可以控制在农艺要求允许的范围内。

ANALYSIS OF TWO CALCULATIONS IN SUGARCANE PLANTER DESIGNING

In this paper,calculations of two parameters of sugarcane planter, diameter and rotational speed of cylinder blade,are analysed.During the chopping process,length of sugarcane cutter is decided by cylinder dia. D,cane dia.d and blade number A as we calculate in usual way.For more accurate results,the acting radius R',formed in deform of rubber tube should also be taken into consideration. Therefore,a new calculating formula is suggested.Supporting by a number of field tests, the author believes that tractor without sychronous power take-off device may also be available for sugarcane planter,provided the whole parameters are matched well and the scheduled operation is carried out strictly.Under that condition,the planting error can be controlled within the allowance permitted by agronomy. In light of this concept,the author developed a new model sugarcane planter 2CZ2- 92,mounted in tractor Dong- 75 and featuring a large cane cutter container.
