A Related Mechanics Characters Analysis And Study Of A New-typed Mechanism Of Millet Threshing

Millet is very nourishing, its economical value has being raised continuously along with the readjustment of agriculture industrial structure and strategic implement of minor crops plant.Shanxi, as one mainly production area, threshing millet is still worked by manpower, in order to improve efficiency, achieve mechanization, so it's demand that design and develop threshing machine for agriculture development.This paper, summarize the development of thresh mechanism and related dynamics trait, test research threshing mechanism and related biomechanics characteristic, explore its direction meanings to design threshing machines, and carry dynamics analysis on a new-typed thresh mechanism ,the item belong to province science and technology committee, do some tests to provide related dynamics parameters for its design.This text, based on search of grain and corn related biomechanics characteristics, announcement the great different between them, in all its biomechanics characteristics accord with statistics pattern. Carried on trial measure size, rate of water, rolling stable angle of, spike and different comparisons glide angle on different surface etc. related mechanics characters. Analysis results saying that: on different material surface, both roll angle and millets rate of water enlarged along with the aggrandized rate of water.Be aimed at the second spike code depart test show: the positions of spikes code and conjunction strength present the line form; the arid degree of the spike has a greatly influence to the conjunction strength. In order to gain some related driving parameter, the static load characteristics research of spikes indicate: The deformation vary greatly when load under 68.2Ns, expressed it have no obvious variety, so 68.6N is a limit before the loose structure is wreck, after then be crushed flat, make sure related work room. At appropriate assumption foundation, built up static pressure mathematics model and carry on the relevant calculation, error of experiment value is smaller than 4%, made sure the homologous work clearance.It preceded the vibration and respond analysts to the dynamic model of the loaded and transportation mechanism, fixed on the one order natural frequency and vibration model. A kind of simple and gentle device to do experiments on spikes. Result enunciation: between slap strength and slap times present logarithms relationship, slap times along with strengths extend but reduce. The regression analysis to experimenting data, find that when slap force catch up to 62Ns, only 10 times continuous work can make thresh rate above to 98%,make sure related bead rhythms of horizontal wave propagation machineThis paper, analyzed with the dynamics and the kinetics to a new-typed mechanism of millet thresh, establish analytical foundation and make sure homologous design parameters for a new-typed mechanism study.
