大蒜播种机机械结构设计

摘要：我国是一个人口大国，在国内每年对大蒜的消耗是很大的，随着更多的进口大蒜产品的增加，但是还是不能满足现有的庞大需求。所以在农业的发展上，每年大蒜的种植量都在增加，使得大蒜播种机在种植和研发生，一直处于供不应求的一个市场发展过程。在现有的国内的市场上出现了很多类型的播种机设备，但是在现有的市场上，很多的播种机在使用上结构性能达不到高效，节能和环保的目的。在农业的大规模的发展下，很多的农业设备也在不断的得到前所未有的发展，在近几年的发展中，不同种类的播种机层出不穷，给大蒜的种植上带来了便捷式的发展。在目前的农业用设备的种植和制造上，不断的机械化的种植的背景下，在传统的使用手动的方式进行转变的形势下，解决了种植的效率比较低的、而且在操作上存在的困难，使得大蒜播种机的经济性能不高等问题的存在，还在种植上不能更好的节省时间。本次设计的的大蒜播种机，适用于在种植农业的需求。现有的市场上大蒜播种机的设计和发展上不断的得到了人们的追捧，因此在本次的设计中，主要针对的种植大蒜播种机的结构的设计，完成关键传动部件的结构形式和钩链式播种结构的结构设计，实现在牵引下的自动化播种的特点，实现关键大蒜正牙播种的设计优势，完成本次课题相关的设计内容。

在本次的大蒜播种机的设计中，在机构的构思上参考了市场上的大型的大蒜播种机的结构设计的方案，对一般的种植使用的大蒜播种机的结构进行构思和设计研究。针对整体结构上设计，在设计中重点对大蒜播种机上的钩链式输送机构、传动部件、链传动减速系统、机架结构等的设计等方进行了重点的结构分析和设计。使得设计的步骤首先在明确本次设计的大蒜播种机的设计任务，在设计的要求上以及设计的背景的情况下，广泛的查找相关的设计的资料，深入明确大蒜播种机的结构设计的纲领，完成大蒜播种机的装配结构设计[2]，并不断的实现部件的优化性的设计，最后对大蒜播种机的绘制CAD结构图纸。

Structural design of key parts of garlic planter

Abstract: China is a country with a large population. The annual consumption of garlic in China is very large. With the increase of more imported garlic products, it still can not meet the existing huge demand. Therefore, in the development of agriculture, the planting amount of garlic is increasing every year, so that the garlic planter has been in a market development process of short supply. In the existing domestic market, there are many types of planter equipment, but in the existing market, many planters can not achieve the purpose of high efficiency, energy saving and environmental protection. With the large-scale development of agriculture, many agricultural equipment are also developing unprecedentedly. In recent years, different kinds of planters emerge in endlessly, which has brought convenient development to the cultivation of garlic. In the current planting and manufacturing of agricultural equipment, under the background of continuous mechanized planting, and under the situation of changing the traditional manual way, it solves the problems of low planting efficiency and operation, makes the economic performance of garlic planter not high, and can not save time better in planting. The garlic planter designed this time is suitable for the needs of planting agriculture. In the existing market, the design and development of garlic planter are constantly sought after by people. Therefore, in this design, we mainly focus on the structural design of garlic planter, complete the structural form of key transmission parts and the structural design of hook chain seeding structure, realize the characteristics of automatic seeding under traction, realize the design advantages of key garlic orthodontic seeding, and complete the design contents related to this subject.

In the design of garlic planter, the structure design scheme of large garlic planter in the market is referred to in the conception of mechanism, and the structure of garlic planter used in general planting is conceived and designed. In view of the overall structural design, in the design, the key structural analysis and design are carried out on the hook chain conveying mechanism, transmission components, chain transmission deceleration system and frame structure of garlic planter. Make the design steps first clear the design task of the garlic planter in this design, widely find the relevant design data on the basis of the design requirements and the design background, deeply clarify the outline of the structural design of the garlic planter, complete the assembly structure design of the straw crusher [2], continuously realize the optimization design of components, and finally draw the CAD structure drawing of the garlic planter.

Keywords:Garlic, planter, hook chain, chain, seed metering.
