履带式油茶垦复多功能作业机越障性能分析及试验

Analysis and Test on Obstacle Surmounting Performance of Crawler Type Multifunctional Machine for Camellia Oleifera Reclamation

为了提高油茶的产量及防治病虫害,必须对油茶林地进行垦复、施肥、修剪、开沟、培土等一系列农艺作业。为此,设计了一款履带式油茶多功能作业机,采用履带式驱动,并配备多功能接头,可以通过不同的作业附件满足油茶不同的作业需求。油茶主要种植在丘陵山地区域,其越障性能是此类作业机械的关键因素。因此,结合履带式作业机越障性能的相关研究成果及此多功能作业机的力学特性,建立了越障力学模型,并通过试验分析了其越障性能,旨在为油茶林地实现机械化作业时所需的地表平整度提供了理论参考。

In order to improve the yield of Camellia oleifera and control diseases and insect pests,a series of agronomic operations must be carried out,such as reclamation,fertilization,pruning,ditching and soil cultivation.In this paper,a crawler type Camellia oleifera multifunctional machine is developed and designed.The machine is driven by crawler type and equipped with multi-functional joint.It can meet the different operation requirements of Camellia oleifera through different operation accessories.Because Camellia oleifera is mainly planted in hilly areas,its obstacle performance is the key factor of this kind of machinery.In this paper,combined with the related research results of the obstacle climbing performance of the crawler type machine,combined with the mechanical characteristics of the multifunctional machine,the obstacle climbing mechanical model is established,and the obstacle climbing performance is analyzed through experiments,which provides a theoretical reference for the surface flatness of Camellia oleifera forest land to realize mechanized operation.
