Study On The Horizontal Centrifugal Spinning Disc Of Manure Spreader

Efficient use of manure nutrients can reduce fertilizer cost and increase organic matter quantity of the farm land and also can meliorate the soil to contain more water ,and minimize the risk of pollution to surface and groundwater and can improve the biology condition, water condition and agriculture atmosphere condition.Manure must be dispose before the use it.. According to the manure moisture content, there are define two type liquid manure and solid manure. Dispose the liquid manure need special pool which must leave far away from the town and the rivers to minimize the pollution. The solid manure can heap on the ground to ferment. This way used widely in China . It also need to cover the manure heap to minimize the pollution.We should adopt different scatter equipment aim at different manure in the foreign country there are many types manure spreader can scatter different types of manure In China, there no spreader used .And the manure spreader research only can find in Jilin Agriculture University. Use manure spreader can meliorate the work condition reduce the work hard, improve the uniformity, and it can improve the enthusiasm of farmers And it is very important for the whole mechanization of fanning, for the ecotypic farming, and also for durative farming.This research study how the spinning disc work on the manure spreader. Because this parts can be used for some manures ,and the well uniformity, so this type used widely.First, we Analyses the movement of the manure particles on centrifugal disc ,and Calculation of horizontal velocity vector and the movement track equation. Provide the math model for simulink. The system was solved by a numerical integration (Matlab function ode45,Runge-Kutta,medium order).Secondly, we select the cylindrical distribution pattern for this research. At last, we make the test-bed for study. From the test we can know the influence factors :, disc rotational velocity, perpendicular distance from the disc center to the first group vanes, perpendicular distance from the disc center to the second group vanes. Use the L9 (34) orthogonal design for the best uniformity.Analyses the test result we know the mostly influence factors is perpendicular distance from the disc center to the second group vanes, the best level is 0.06m,the second is manure moisture content, the best level is 15.4%,the third is perpendicular distance from the disc center to the first group vanes it best level is 0.003 85m,the last is disc rotational velocity, it best level is 140r/min.For the sake of avoiding the shortage of the former analyse we use the other analyse for test data,find the facter D (the eccentricity distants of the second group vane)A(contenting water rate) C(the eccentricity distants of the first group vane) these three factors influence notability the reliability of this judge is 99 percent analyse this can know that the factors of influence test order is D A C B.From the test result we know the best project ,but we have not do this. So we must do additional test to validate the forecast. The additional test used the samecondition. Ensure the test result at the same condition. After the test we find the best uniformity, so this group levels is the best.This research obtain the best level of each factors. And it is the base of the manure spreader.
