The Study And Analysis Of Nacelle-type Transplanter

Raise seedlings and transplant can increase crop production in every unit area, and make upgrowth ahead of time, which can withstand gale, harmful rain, low temperature, and other nature disaster. Besides, it also saving seed. Because of the weather condition in Xinjiang province, seeds are usually grown under the film by farmer, it is useful to improve the soil temperature, keep moisture and restrain weeds. Punch transplanted is precondition of foison for the farmer in busy spring.Punching transplanting is a normal agricultural technology in china, but the traditional and manual methods of transplanting have many problems which could not be resolved up to now. So it is an immanency task to realize transplanting mechanization in China.The nacelle-type transplanter is a good machinery for transplant film, but it is not convenient and safe to directly drop seedling and it is easy to leave out seedling when the machine is operated and its work efficient is low when seedlings are transplanted over the larger areas. Now a simple and credible type of machine was designed, which was easy and convenient to be operated and adjusted. The efficiency of the machine is much more greatly improved. There is less seedling to leave out in work progress.The thesis chooses proper transplant outfit for the new design by the research of variety of transplant outfit virtues and draws three dimension model of the whole transplanter by SolidWorks software. The thesis carries out finite element analysis on the key parts by COSMOSWorks software and judge the reliability. The thesis simulates the nacelle transplanter locomotion by COSMOSMotion software and analyzes the motion track. In the last, the thesis analyzes the seedling drop process and adjustment principle for differ seedling distance.
