Abstract


The cleaning device is an important part of the combine harvester , it directly affects the performance of the whole machine . Improve the quality of the cleaning combines will be to solve the key issues of the further development of China 's rice production . On the basis of pre Experimental study of the longitudinal axis of the flow threshing and separating device corresponding cleaning device trials supporting research , in order to improve the performance of the device , for the design of new models and the modification of the conventional models provide reliable basis. In this paper, the longitudinal axis of the flow wind screen cleaning device test bench as a platform to power , impurity rate and loss rate performance indicators to crank radius , the screen surface inclination , fish scale sieve opening degree , cross flow fan speed parameters above parameters on the performance indicators , the vertical and horizontal distribution of and undersize material and impurity rate along the screen surface . Quadratic orthogonal rotation combination design with three factors and five levels , the establishment of a regression equation between the various factors and performance indicators . Use of the the performance regression equation , the main objective function method , using MATLAB optimization solutions , has been optimized parameters : crank radius 14mm screen surface inclination of 10 °, the ichthyosis sieve opening degree of 8 ° .
