林间车载式刺五加割灌机的设计与试验OA

The aim of this research was to address the issues of poor terrain adaptability and low cutting efficiency of the Acanthopanax senticosu brush cutting equipment.Design an in-forest circular saw type Acanthopanax senticosu brush cut-ter mounted on the front of a tractor.Through structural design,it was clarified that the entire machine consisted of four core mechanisms:support adjustment,transmission,brush cutting and feeding.The support adjustment mechanism and feeding mechanism were developed,and the motion trajectory and cutting force of the circular saw blade in the cutting mechanism were analyzed to validate that its power met the requirements.Field experiments were conducted with the ro-tational speed of the circular saw,traveling speed,and cutting height as influencing factors,and the experimental data were processed using data processing software.The results indicated that traveling speed had the greatest impact on the cutting efficiency of the brush cutter,followed by the rotational speed of the circular saw,while cutting height had the least effect.Using Design-Expert13 software,a regression model for cut rate was constructed and parameters were opti-mized.It was obtained that the influence degrees of each factor on the cut rate from large to small were the traveling speed,the rotational speed of the circular saw,and the cutting height.When the rotational speed of the circular saw was 1 925 r/min,the traveling speed was 4.2 km/h,and the cutting height was 39.6 cm,the cut rate reached 99.4%,resulting in the best cutting performance.This equipment can meet the efficient brush cutting needs of Acanthopanax senticosus in complex forest terrain,providing technical support for mechanized pruning in large-scale Acanthopanax senticosus planting.
