| Rice is main food crops in China, and its safety in production is of great significance. fertilizer is the indispensable link in the process of rice growth, fertilizer has a deep make full use of fertilizer efficiency, reduce fertilizer field volatilization, improve the utilization rate of fertilizer to promote rice growth, increase rice yield, reducing environmental pollution and water pollution. design of a high speed, strong commonality of applying fertilizer in paddy field device, increase rice production to ensure the safety of food production, reduce cost, increase efficiency, improve the whole rice production mechanization.This paper reviews the recent development of mechanical fertilization,and Analysis of the current development and application situation of paddy field fertilizing machine,for paddy field and wet work environment caused by chemical fertilizer deliquescence agglomerate, overhead problems such as overall scheme of applying fertilizer in paddy field device is put forward. Adopts theoretical analysis, computer aided design and analysis method to carry on the design of key components, and through the experiment of applying fertilizer in paddy field device performance and fertilizer consumption and study the relationship between the influencing factors, the main research work is as follows:(1)According to the current situation of the development of paddy field fertilizer machinery and paddy field machinery application and characteristics of the working environment, design a simple structure and reliable device applying fertilizer in paddy field.(2)According to the scheme design, applying fertilizer in paddy field device components including fertilizer box, internal components, fertilizer(horizontal and vertical screw wire mesh, etc.), leaf type fertilizer consumption adjusting device, opener, such as components, the use of Pro/E software rendering 3 d model components, respectively, after interference check and modify the size, determine the structure size of the items constituting the applying fertilizer in paddy field device and assembly relations.(3)The theoretical analysis of the vane fertilizer consumption structure and the mechanism of adjusting device, using VB 6.0 software written vane fertilizer consumption conditioning movement analysis program, calculate the bad XieQun of fertilizer consumption control device structure. According to the non inferior XieQun limits, use VS write fertilizer consumption conditioning parametric design software, the application of the software for optimal fertilizer consumption control device structure.(4)According to the fertilizer machinery national standard test performance of the paddy fields deep device. Using the methods of static test and dynamic test, the test device applying fertilizer in paddy field distributing ability, distributing, distributing uniformity, stability performance indexes such as the rate cut off. Through theoretical analysis and data, each work index comply with the provisions of the national fertilizer machinery standards.(5)By using single factor experiment analysis factor influences each fertilizer consumption. With fertilizer fertilizer consumption and test in the car speed and the opening diameter of fertilizer consumption conditioning test factor, fertilizer consumption as test index, the Design-Expert 6.0.1 software analysis the test data, test factor is obtained with the test index between the change rule.(6)Using quadratic orthogonal rotation combination test, after the Design- Expert 6.0.1 software on the analysis of test results for each experimental factor on comprehensive test index; Analysis of each experimental factor combination condition test contribution rate, the index for each factor influences test index of primary and secondary relations; With cold rice in different soil fertilizer, on the basis of economic optimizing the best parameter of the applying fertilizer in paddy field device. |
