Parameters Design and Experiment on Self-propelled Salix psammophila Stumping Machine

阐述了自走式沙柳平茬机结构及工作原理,并针对自走式沙柳平茬机平茬作业过程中锯片转速与行走速度匹配问题,对其切割锯片线速度、机具行走速度等工作参数及驱动底盘进行了设计与试验。试验结果表明:沙柳平茬作业适宜的切割器线速度为50 m/s;机具行走速度由灌丛大小及植株密度决定;机具沙地行走有效爬坡角度小于10°。

The structure and working principle of the self-propelled Salix psammophila stumping machine were described.And aiming at the saw blade rotation speed and walking speed matching problem of the machine,the design and experiment on the working parameters were carried out,such as cutting saw blade linear velocity and machine walking speed,and the structure of the drive chassis.Results of the trial were summarized as follows.The proper linear cutting velocity for Salix psammophila stumping was 50 m/s.And the machine walking speed was determined by the brush size and plants density.The effective uphill angle of the machine walking on sand was less than 10°.
