Research Of No Line Feeding Device In Corn Harvester Header

The first step of corn harvest is the feed of the corn stalks, if the no line feed of the corn stalks can be achieved,the corn harvest machine’s row spacing adaptability can be improved, also the realize of the no line corn harvest have the reality feasibility. While the development of wrong line corn harvest technology also has its practical significance. At present, US、Germany and other developed countries in the space of corn harvest has significant achievements. Many company in our country have started the development of corn harvest machine. But the structure of the machines is very complex, the power consumption is really large, spaced adaptation have not been well improved.In this paper, the domestic and foreign advanced no line corn harvest technology were analyzed and compared and absorb innovation. at the same time taking into account the adaptability of Forage harvesting machinery, such as line spacing better machinery. Summed up several plan of the no line corn harvester cutting unit feeding device can realize harvesting, and for a variety of programs carried out a feasibility analysis. Ultimately determine the new scheme for which adapted new divider into, disc type cutting knife to cut the corn plant, reel drum and sprocket type conveying chain supplementary feeding. The device can be very good to improve the adaptability of corn harvesting machinery space, realize the no line corn harvest machine harvesting operations, improve work efficiency, reduce the power consumption of the system effectively, enrich and perfect our no line corn harvest technology.In the course of this project complete the overall scheme of no line corn harvester, identifies key components of the motion parameters. On new divider, disc cutter, dial to determine roller and chain gear conveying chain of the structural design and motion parameters. Take the effective feeding of the header in no line harvesting as the basic principle, give full consideration to the stress and the operation effect of key components and considering the interaction between the coordination of the key components of the device, which can have a good row spacing adaptability in operation.After the key components of the design is complete, using ANSYS/Workbench on the disc cutter blades, cutter head and cutter for modal analysis and obtained their first six natural frequencies, and parts of itself in the normal working hours are calculated vibration frequencies compared to avoid resonance phenomena occur, the structural design of key components of safe and reliable conclusions.At the end of the article this subject is summarized and prospected, demonstrates the feasibility of the practical significance of this design.
