Abstract
 This article provides a preliminary design and calculation analysis of the trenching machine, a mechanical equipment. The trenching machine is a commonly used mechanical equipment in engineering and the plant industry in China. This type of equipment has a lot of room for application in multiple industries. This article mainly designs multiple systems of the trenching machine as a mechanical equipment. This mainly includes the selection of diesel engines, the design and calculation of multiple mechanisms such as transmission systems, walking systems, and actuators. [版权所有：http://think58.com]
This article calculates and optimizes the transmission ratio of the transmission system; By establishing a model of the cutting tool, conducting simulation analysis, focusing on designing the cutting tool, conducting detailed force analysis and motion analysis of the cutting tool groove, and calculating and analyzing key components such as the sprocket and sprocket shaft. Finally, by comparison, a vertical spiral trenching machine structure was adopted. The trenching machine designed in this article has the characteristics of simple structure, good mechanism economy, and easy maintenance. It can significantly improve the work efficiency and economic benefits of the equipment.
Key words: Spiral trenching machine; Orchard; Tool design; Chain wheel design
