丘陵山区小型自走式茶园中耕机设计与试验
Design and Experiment of Small Self-propelled Tea Garden Tillage Machine in Hilly and Mountainous Areas
摘要
Abstract
Aiming at the difficulties of poor performance of soil tillage and soil breaking operations in tea gardens in hilly and mountainous are-as of China,a small self-propelled tea garden tillage machine was designed.A mathematical model for the motion position of the soil breaking mechanism of tillage machine was established,the key parameter design of the soil breaking mechanism was optimized by the kinematic analy-sis.In addition,the key components of the tiller such as the soil breaking blade,transmission system,depth limit wheel,and frame were de-signed in detail,so to ensure the operational efficiency and stability of the entire machine.Taking the soil breaking rate and the stability coeffi-cient of the tilling depth as the test indicators,and taking the forward speed and the angle of penetration as the test factors,a comprehensive randomized field experiment was conducted.The results showed that the soil breaking rate of the machine gradually decreased with the increase of forward speed.When the forward speed was fixed,the stability coefficient of the tilling depth showed a downward trend as the angle of pene-tration increased.At the time of ensuring the operational efficiency,excessive forward speed and angle of penetration should not be selected.The optimal operation combination was forward speed of 1.5 km/h,and the angle of penetration of 45°.关键词
