ABSTRACT

This topic comes from the actual demand of the development of agricultural mechanization and the in-depth analysis and research of the existing leek harvester technology. Considering the wide distribution of leek planting industry in China and the growing market demand, the function and efficiency of the existing leek harvester still need to be improved. Therefore, this study aims to design a novel leek harvester to meet the demands of small businesses and vegetable farmers for efficient, stable and low-damage harvesting equipment. The topic not only focuses on technological innovation, but also focuses on the stability, convenience and cost effectiveness of mechanical function, to promote the sustainable development of leek harvesting technology.

This study focuses on the innovative design and performance improvement of leek harvesting equipment in China. In view of the shortage of the current leek harvesting equipment and the actual market demand of the market, this study proposes a new type of leek harvesting equipment. The equipment consists of key components such as power input system, cutting mechanism, transmission system, microemulsion spraying system and harvest collection system. By using a small diesel engine and a crank linkage mechanism, the driving force transmission of the equipment and the leek cutting operation are realized. In the design process, special attention is paid to the mechanical stability of the equipment, cutting quality and the integrity of the leeks, and strive to minimize the damage to the leek roots and leaves in the harvest process. This paper details the selection of power transmission mode, the design of working device and transmission device, and completes the 2 D and 3 D modeling with AutoCAD and SolidWorks software. The research results of this paper provide theoretical and technical support for the further development and promotion of leek harvester.
