Research Of Mixing Fertilizer Plant For Sugar Cane Row Ridging Fertilization Machine

Sugarcane is the largest planting areas tropical crops in China,its planting area accounts for more than 85%of our sugar plantations,in 2013,sugarcane cultivation in our country about1.816 million hectares,and sugarcane row is of vital importance.At present our country own micro machine and small machine,the problem is big ridging machining labor intensity,the function is not comprehensive,work efficiency is too low;while foreign large cane machinery exists wide spacing,high prices,complex structure and so on.Therefore,we design the transmissions device,mixing fertilizer device and other main parts,and studies on the distributing regularity of the distributing device.Not only develop distributing uniformity,but also solve some problems such as work efficiency is too low,the shaft is easy to break down.The research content and conclusions are as follows:(1)The design and research of the mixing fertilizer equipment:with the impeller through a fixed shaft installation fixed in a fertilizer bucket,fence,the upper and lower bushing was placed directly in the barrel fertilization,it’s easy to disassemble and block the fertilizer on the top impeller before mixing,decreasing impeller rotational resistance,realizing shearing without overhead of the three kinds of fertilizer,reducing auxiliary workers,improving the work efficiency and reducing the operation cost.This passage introduce the working principle of the machine,we also make sure the evidence of the size of the mixing fertilizer device with the structure of fertilizer device.We designed 2D models with CAD software,and we set 3D models for the parts through the Solid Edge parts,mixing fertilizer device for motion simulation,then summarized the mechanism motion characteristics,and checked theory parameters,we could verify the rationality of structure.(2)Design and research of the transmission mechanism,we could reduce the cost by using the advantaged transmission,designed the shaft,individually analysed the shaft stress deformation by using Solid Works software simulation and ANSYS software,it is concluded the deformation was small enough to ignore,it means that the design is reasonable,increase the stability of machine.(3)The test and structure optimizationwe got three groups of the significant affecting factors.By designing the Box-Behnken test scheme and using SAS software for data processing,we finally established the mathematical model of distributing rule,and we verified the best parameters group from the Box-Behnken test.(4)The results indicated:Through the Box-Behnken test,we finally got that influence degree from high to low is:width>scraper scraper Angle>speed;distributing uniformity with the increase of the parameters showed a trend of decrease after the first increase;the best parameters group could achieve when the scraper width was 48.4 mm,scraper Angle was 16.5°,speed was 1.09 m/s.Finally,verifying by the test,we got the result was same with the theoretical analysis values,the results indicated:distributing uniformity reached 92.3%,trenching depth was 16.6 cm,trenching depth stability coefficient reached 92.9%,higher than the requirements of general machinery industry standard(85%),fertilizer coverage rate could get 100%,sugar cane injury rate was 1.8%,the working hour rate was 0.51 hm~2/h,operation effects reach the national standard.
