Abstract
Based on the mechanical structure design of small automatic ground grain harvesting machine, this paper designs a new one with high efficiency, energy saving and environmental protection from the aspects of treatment efficiency, economy and environmental factors.
In this paper, the whole machine is designed to determine the functions of the parts, and determine the parameters of the speed and weight of the grain collector, and the stability and safety of the grain collector. At last, the analysis is made of the parts drawing and the general assembly drawing.
After experimental calculation, under the premise of the net yield of 99%, this design scheme not only has the characteristics of high efficiency, stability and reliability, but also has the environmental advantages of low energy consumption, low noise and no pollution, which better solves the problems of high labor intensity and low efficiency in traditional grain harvesting methods.
To sum up, the research results of this paper have certain theoretical and application value in realizing mechanized green grain harvest, and have certain reference significance for promoting the modernization and intelligent pattern of grain production in China.
