摘　　要：目前,我国天然橡胶园割胶主要以人工为主,劳动强度大、效率低、工作环境恶劣,本研究设计了一种固定复合运动轨道式割胶机.首先,通过Solidworks三维建模方法建立整机模型;其次,对其固定装置、复合运动装置、切割装置等关键部件进行设计,并用Ansys对切割刀片进行静力学分析,得出切割刀刃受到最大应力时满足其安全裕度、符合刀片强度的设计要求;最后,通过选取干胶产量为响应值,切割角度、切割深度、耗皮厚度为显著性参数,基于Box-Behnken设计试验得到响应值与显著性参数的二阶回归模型.试验表明,当切割角度为28°、切割深度为5.5 mm、耗皮厚度为1.6 mm时,干胶产量达到最佳为178.4 g,与田间验证试验结果(176.7 g)的误差仅为0.9%,验证了分析的可信性,证明了割胶机结构的合理性和运动的可靠性.本割胶机在替代人工劳动、提升橡胶产量等方面有显著效果.At present,rubber tapping in natural rubber plantations in China is mainly manual,which is high labor intensity,low efficiency,and with harsh working environment.This study designed a fixed composite track type rubber tapping machine.Firstly,establish the model of the whole machine through Solidworks three-dimensional modeling method.Secondly,design the key components such as the fixed device,compound motion device,cutting device,and use Ansys to conduct the static analysis of the cutting blade.The results indicated that the cutting blade meets its requirements under maximum stress.The safety margin of blade strength meets the requirements of the design.Finally,by selecting the dry glue output as the response value,and the cutting angle,the cutting depth,and the skin thickness as the significant parameters,the second-order regression model of response value and the significant parameter are obtained based on the Box-Behnken design test.The test showed that when the cutting angle was 28°,the cutting depth was 5.5 mm,and the skin thickness was 1.6 mm,the dry glue output reached the best value of 178.4 g,and the error with field verification test result(176.7 g)was only 0.9%.The credibility of the analysis is verified.The rationality of the structure and the reliability of the movement of the tapping machine were proved.The tapping machine has significant effects in replacing manual labor and increasing rubber output.
