Abstract

Background: In response to the current need for the development of large-scale wheat combine harvesters, this paper carried out the structural design and performance test of a large feed volume wheeled wheat combine harvester.

Methods: Based on the characteristics of wheat plants, this paper designed a wheeled wheat combine harvester with a feed rate of 10kg/s. Subsequently, the structural parameters and design process of the main working components, such as the header feeding device, the conveying device, the threshing device, the separation and cleaning device, the walking device, the cab, and the straw crushing device, are elaborated. The strength of the key parts was checked by finite element simulation, and the structural parameters were optimized.

Results: The results show that the large feed volume combine harvester which designed in this paper can achieve an entrainment loss rate of less than 2.39% and a cleaning loss rate of less than 0.26%, significantly lower than the current 3% loss rate and there is almost no unclean and broken situation.

Conclusion: This research provides a reference for the design of a large feed volume combine harvester.

Keywords: Numerical modeling, wheel structure, wheat, threshing effect, harvest performance
