1、长春工业大学本科毕业论文 微型玉米剥皮机设计 摘要 在玉米分段收获时，玉米剥皮工序劳动强度大，费工时和误农时，且影响玉米的质量和质量等问题，针对我国玉米收获后剥皮这个重要环节，设计出场上玉米剥皮机，并对其结构及技术参数予以设计。微型玉米剥皮机是收获玉米穗外表皮的一种机具，本机为4辊机型，可满足单户、联户和种粮大户使用。它代替了传统人工剥皮的紧张劳动，减轻了人们的劳动强度，提高了劳动效率，有效地防止了因剥皮不及时而造成的玉米霉烂损失，该机结构简单，调整方便性能可靠，生产效率高，可采用电动机、柴油机或三轮农用运输车发动机作动力，本机采用单相交流电动机作动力。剥皮装置中剥皮辊一般有螺旋铁棍和橡胶辊组
2、成，铁棍对籽粒有严重损伤，所以本机要求采用全橡胶辊。在满足剥净率95%以上。工作效率达到1500kg/h，动力源3kw的设计要求的前提下进行设计。为达到设计要求，主要剥皮装置采用全橡胶的玉米剥皮辊，并且两辊高低设置，且可以根据玉米棒的大小不同调节两辊间的距离。这避免了传统设计方法中采用铸铁辊对玉米籽粒的损坏，而且在结构上比传统设计方法更为合理。经计算、校核，该机符合设计要求，并且在剥皮装置与传统方式上较传统设计有所改进，更适于在广大农村的推广应用。【关键词】 玉米剥皮机 剥皮辊 传动系统 动力源 1Title: Corns Clothes Takes-Off Machine Abstract
3、At the devided harvest time, the labor force of corns clothes take-off by hard is to strong. It wastes time and decreases the quantity of the corn. To solve the problem of corns clothes take-off in our country, we designed the corns clothes take-off machine including the structure and the technical
4、parameter design. It is a machine that take off the corns clothes. It has four types, respectively for single, union of several and big harvest. The machine instead of the traditional handed labor, reduce the peoples labor strength, raise the efficiency and prevent the corns damage. The structure of
5、 the machine is simple. The machine is easily adopted, reiable and efficiency. The power of the machine can use electric motor、diesel engine and the power of agricultural car.This machine adoption list mutually the alternate current motive makes the motive. Peel to equip to win to peel the son of to
6、 have the spiral iron casting son of and the rubber son of to constitute generally, cast iron the son of to have severity to the seed grain to hurt, so this machine adoption the whole rubber son of. Designed under premise that must be get go 95% of take-off rate and efficiency required no less than
7、1500kg/h, power no more than or equality 3kw. For get to these requirements, main take-off part makes use of rubber cylinder, and they are installed up-down. It is more reasonable than orthodox way. The transmission system makes use of binary level decreasing velocity. Via computed and checked, the
8、machine is right. Specially, it is better than forming designing. Worthwhile, it is widely applied in rural.Key words: Corns clothes、 Take-off Machine、 Cylinder、 transmission system、 Power resource 目录摘要-1Abstract-2引 言-11 题目来源及技术要求-11.1 任务来源-11.2 剥皮机的设计要求如下-21.3 玉米剥皮机结构简介-22 总体方案的分析-32.1 剥皮的工艺过程-32.2
