摘 要
随着农业现代化的推进，自动化、机械化播种技术已经成为提高农业生产效率、减轻劳动力负担的重要途径。大蒜作为我国重要的蔬菜作物之一，其播种过程中的自动化水平相对较低，仍存在大量依赖人工操作的环节。因此，开发一款高效、实用的大蒜播种机具有重要的现实意义和应用价值。此外，市场上的大型大蒜播种机虽然功能较为完善，但往往价格昂贵，对于一般种植户而言难以承受。因此，设计一款结构合理、性价比高的大蒜播种机，可以满足更多种植户的需求，推动大蒜种植业的健康发展。在选题过程中，通过查阅相关文献资料、了解市场需求和技术发展趋势，发现大蒜播种机的机械结构设计是一个具有挑战性和创新性的课题。通过深入研究和实践，可以探索出更加高效、实用的机械结构设计方案，为大蒜播种机的研发和推广提供技术支持和参考。
本文旨在设计一款大蒜播种机的机械结构，以满足大蒜种植过程中的自动化需求。设计过程中，参考了市场上大型大蒜播种机的结构特点，并结合实际种植需求，对播种机的钩链式输送机构、传动部件、链传动减速系统以及机架结构等关键部分进行了深入的结构分析和设计。通过明确设计任务、广泛收集相关资料、明确设计纲领，完成了大蒜播种机的整体装配结构设计，并不断优化各部件的性能。最终，绘制了详细的CAD结构图纸，为大蒜播种机的制造和实际应用提供了重要的技术支持。本研究对于提高大蒜种植的自动化水平和效率具有积极的推动作用。

Abstract
With the advancement of agricultural modernization, automatic and mechanized sowing technology has become an important way to improve agricultural production efficiency and reduce the burden of labor force. As one of the important vegetable crops in China, garlic, the level of automation in the sowing process is relatively low, and there are still a lot of links relying on manual operation. Therefore, developing an efficient and practical garlic planter has important practical significance and application value. In addition, although the large garlic planter on the market is relatively well-established, it is often expensive and difficult for the average growers to bear. Therefore, the design of a reasonable structure and cost-effective garlic planter can meet the needs of more farmers and promote the healthy development of garlic planting industry. In the process of topic selection, the mechanical structure design of garlic planter is a challenging and innovative subject by consulting relevant literature and understanding the market demand and technological development trend. Through in-depth research and practice, a more efficient and practical mechanical structure design scheme can be explored, to provide technical support and reference for the research and development and promotion of garlic seeder.
This paper aims to design the mechanical structure of a garlic planter to meet the automation requirements in the garlic planting process. In the design process, referring to the structural characteristics of the large garlic planter in the market, and combined with the actual planting needs, the structural analysis and design of the hook chain transmission mechanism, the transmission parts, the chain transmission and deceleration system and the frame structure are conducted. Through the clear design task, the extensive collection of relevant data, and the clear design program, the overall assembly structure design of the garlic planter has been completed, and the performance of each component has been continuously optimized. Finally, the detailed drawings of the CAD structure were drawn, which provided an important technical support for the manufacture and practical application of the garlic planter. This study has a positive impetus to improve the automation level and efficiency of garlic cultivation.
Key words: garlic planter; mechanical structure design; hook chain conveying mechanism; transmission parts; chain transmission deceleration system
