种子裹衣机设计
摘 要
林木种子的裹衣是种子处理中的一项具有开发前景的新技术。它是利用专业用的配套设备，按着一定特有的工艺流程和物料配方方案所完成的种子规格化处理技术。它通过粘合剂将物料包裹在种子的表面，形成一定厚度的衣壳，使种子的外形尺寸达到规格化，就可便于实现机械化作业。采用种子裹衣加工不可以改善种子形状，还能改善其强度等物理特性，为一些小颗粒的种子，还有不规则的种子创造良好的条件，可以促进它们的生长，同时也能节约成本、保护环境，对保障食品的安全起到了重要的意义。
本文首先介绍了种子裹衣技术的背景、概念、意义、目的、设计要求其裹衣技术的加工原理以及其加工工艺过程和发展展望。然后在此基础上，对所研发设备的关键零部件进行选型，改良设计。特别介绍了种子裹衣机的结构以及设计重点，介绍了国内外的研究现状。并对种子裹衣机的发展前景做了简要叙述。
根据其加工工艺，设计供粉装置，进一步完成裹衣整体设备的方案设计。优化了供粉装置，使其装置更简便，更轻巧。将原设备上的带传动转动起风改成了鼓风机供风，使其简单化，而且也增强了供风的稳定性。为了能准确，简单的控制裹衣锅的倾斜角度，从原有的基础上，在减速箱的外壳和轴承端盖上加了档位器，使其简单的控制裹衣裹的倾斜角度。
我国种子裹衣技术才刚刚起步，还需要进行全方位地提高，这是一个任重道远的过程。可喜的是国家对这个产业的投入不断增加，种子企业对其的关注不断的提高。我们相信，通过正确的引导，理论的完善，科研水平的不断进步以及整个种子领域对质量要求的不断提高，在不久的将来，我们会逐渐缩短与发达国家的差距，从而为种子公司带来更大的利润，为农民减少投入、增加收益。

Forest Seed Coating Machine Designing
Abstract
Cloak of tree seeds is a new promising technology in seed treatment. Following specific technological process and material formula solution, it is a normalization technology of seed using appropriative corollary equipment. The material is wrapped outside the surface of the seed by adhesive as a capsid in order to normalize the seed shape and realize mechanical operation. Cloak-treating can not only change the seed shape, but also improve its physical properties, such as strength. It can provide a good environment for seeds of small and irregular shape and boost their growing. At the same time, cloak-treating can reduce the cost and protect the environment, which is meaningful to guarantee food security.
This paper introduces the background, concept, meaning, aim of cloak-treating, the processing principle the design requires, the operational process and the development prospect. On this basis, key components of the designed equipment are chosen and improved, e.g. gyration kettle, powder-offer device, heating arrangement, the whole frame, etc. This paper especially introduce the structure and design emphasis of cloak-treating equipment, the research status both at home and abroad as well as the brief description of its development prospect.
According to its operational process, powder-offer device is designed to complete the whole equipment. It optimizes the powder-offer device, which is made to be more simple and convenient. Wind is blown from turning to fanning, which is more simple and strengthen the stability of wind- supply. In addition, gear position indicator is added outside the reducer and in the bearing end in order to control the gradient of cloak easier and more accurate.
Cloak-treating technology is just starting out in our country and still needs improving in all directions, for which we shoulder heavy responsibilities and have a long way to go. The good news is that China is increasing the investment in this industry and seed enterprises are paying more attention to this technology. We believe we will gradually shorten the gap with developed countries in the coming future through proper guidance, impeccable theory, progressive science technology and elevated requirements for seed quality, thus seed enterprises will gain more profits, and farmers can also cut inputs and increase revenues.
Key Words: seed, cloak-treating technology, optimized design, development prospect
