Optimal Design and Experiment of Corn-Overlapped Strip Fertilizer Spreader

چکیده
As the complex terrain in hilly areas is not conducive to corn mid-tillage precision fertilization, a corn-overlapped strip fertilizer spreader was designed without an external power source. By configuring passive overlapping spreading method with three-branch split chamber structure, uniform of strips achieved. A horizontal and vertical movement model developed determine angle extending tube, width fattening small plates, height spread as main factors affecting distribution pattern. The single-factor ternary orthogonal rotational combination response surface simulation test carried out pendulum angle, width, transversal uniformity coefficient longitudinal indicators. results showed that height, had significant effects (p < 0.05) on coefficient, considerable impact coefficient. In optimal parameters, swing 52°, 400 mm, 50 mm operation, coefficients both were less than 0.15%. verification under parameters for tests conditions standard. consistent within error range. deviation values 8.11% 9.01%, respectively. able complete operation smoothly. This study provides evidence further optimizing performance applicator.

1 Spatial Optimization of Fertilizer Application by a Centrifugal Spreader
Fertilization practice using centrifugal spreaders generally consists in the mass flow rate regulation thanks to the simple mathematical relation D=Q.L.V/600 where Q is the prescribed fertilization rate, L the working width and V the tractor speed. Modern machines equipped with DPAE device can thereby continuously control the mass flow rate with respect to the working width that is in most case...

This paper presents an experimental design approach to the process parameter optimization for compocasting of A356-SiCp composites. Toward this end, parameters of stirring temperature, stirring time, stirring speed and SiC content were chosen and three levels of these parameters were considered. The D-optimal design of experiment (DODE) was employed for experimental design and analysis of resul...

متن کاملComparison of Exactrix and Conventional Fertilizer Application in Corn
Introduction The cost of nitrogen fertilizer increased dramatically in 2008 compared to previous years. As a result, producers began looking for ways to increase their nitrogen use efficiency. One product being promoted was an Exactrix system that injects anhydrous ammonia (NH3) as a liquid. The manufacturer of the Exactrix system claimed that nitrogen (N) rates could be reduced by as much as 3...
