【摘要】：巴彦淖尔市地区具有特殊的地理位置和气候条件,是青椒、番茄、向日葵、籽瓜、籽用西葫芦等经济作物的生产基地。随着消费者对西葫芦瓜子的喜爱,籽用西葫芦在巴彦淖市地区的种植面积越来越大。打籽西葫芦成熟时期是多种农作物同时成熟收获时期,需要大量劳动力,对大型自走式葫芦收获机械进行改进。解决劳动力紧缺,缩小劳动时间,给农民带来可观收入。论文主要研究内容包括以下几个方面:(1)通过对国外籽用西葫芦收获取籽机的原理及结构进行研究,找出现有籽用西葫芦机的缺点,分析籽用西葫芦收获取籽机的工作机理,结合籽用西葫芦的种植持性和规模,对辊筒部件进行改进设计。(2)利用SolidWorks对籽用西葫芦收获取籽机辊筒部件进行三维建模,在ANSYS Workbench中进行辊筒部件在改进前后的静力学分析,确定改进后的辊筒部件强度满足生产要求。(3)制造籽用西葫芦收获取籽机样机,通过田间捡拾试验,获得辊筒部件的捡拾率。
[Abstract]:Bayannur City has special geographical location and climatic conditions, it is the production base of green pepper, tomato, sunflower, seed melon, seed zucchini and so on. As consumers love zucchini seeds, seed zucchini is growing in Banao. The ripening period of seed zucchini is the period of multiple crops at the same time, which needs a lot of labor to improve the large-scale self-propelled gourd harvesting machine. Solve labor shortage, reduce labor time, bring considerable income to farmer. The main research contents of this paper are as follows: (1) through the research on the principle and structure of the seed pickling machine used in foreign countries, the shortcomings of the seed pickling machine are found, and the working mechanism of the seed pickling machine is analyzed. According to the planting capacity and scale of seed zucchini, the roller parts are improved. (2) 3D modeling of the roller parts of seed zucchini harvesting machine is carried out by SolidWorks, and the statics analysis of roller parts before and after improvement is carried out in ANSYS Workbench. It is determined that the strength of the improved roller parts can meet the production requirements. (3) the prototype of the seed machine is obtained by using the zucchini harvest to produce seeds, and the picking rate of the roller parts is obtained through the field picking experiment.
