【摘要】：现在,全世界60%的人口以稻米为食,稻米对人们的生活有着极其重要的影响。各国对主要作物的种植也是格外重视。我国东北地区,春季的气候有些干燥和寒冷,这个时候对水稻的生长是十分不利的,所以在种植水稻之前,在水田表面覆盖一层塑料膜就变得极为重要。目前大多数地区的人们都采用手工覆膜,这样一来,导致工作效率低下。同时插秧机进行插秧时,秧爪夹着秧苗接触塑料膜时,可能发生弯苗、折苗的情况对水稻的种植产生较大影响。针对这一情况,本文设计了快速覆膜机,该装置进行自动覆膜的同时采用打孔机构对塑料膜进行打孔,同时确保分插机构在插秧时顺利将秧苗插入塑料膜的孔中。并能同时进行,压边,扶泥等工作。具体研究内容如下:本文首先应用CATIA建立了快速覆膜机的三维模型,并完成了装配。其后通过作图法和MATLAB优化确定了覆膜机打孔机构的主要参数,并且对打孔机构进行了运动学分析和受力分析。最后用ADAMS对打孔机构进行了运动仿真,结果表明秧苗能够插入打孔机构所打出的孔中。
[Abstract]:Today, 60% of the world's population feeds on rice, which has an extremely important impact on people's lives. Countries also attach great importance to the cultivation of major crops. In Northeast China, the spring climate is a little dry and cold, so it is very unfavorable to the growth of rice at this time, so it is very important to cover the paddy field surface with a plastic film before planting rice. At present, people in most areas use hand-coated film, which leads to inefficient work. At the same time, when transplanting seedlings were carried out by transplanting machine, when the seedlings clawed with plastic film, the curved seedlings might occur, and the folding of seedlings would have a great influence on rice planting. In order to solve this problem, this paper designs a rapid film laminating machine, which can automatically cover the film and use the perforating mechanism to perforate the plastic film. At the same time, it can ensure that the transplanting mechanism inserts the seedling into the hole of the plastic film smoothly when transplanting seedlings. And can be carried out at the same time, edge pressing, clay, and other work. The main contents are as follows: firstly, the three-dimensional model of fast laminating machine is established by CATIA, and the assembly is completed. After that, the main parameters of perforating mechanism of laminating machine are determined by drawing method and MATLAB optimization, and the kinematics and force analysis of perforating mechanism are carried out. Finally, ADAMS was used to simulate the motion of the perforating mechanism. The results showed that the seedling could be inserted into the hole made by the punching mechanism.
