摘要
利用设计的秸秆还田机粉碎装置进行了粉碎试验。以壳体包角、喂入速度、动定刀间隙为试验因素,秸秆的粉碎质量、粉碎功耗为试验指标,建立了粉碎质量和粉碎功耗的数学模型。随着喂入速度、壳体包角的增加和动定刀间隙的减小,粉碎功耗增大,粉碎质量提高。利用回归方程和主目标法,进行了参数的优化设计,结果为:粉碎室包角为70°、喂入速度为46.5m/s、动定刀间隙为10mm。
Smashing experiment has been done with help of smashing devices of the stalk macerator which self-designed. With shell angle, feeding velocity and distances of rotatory blade and fixed blade as test elements, with the samashing performance and power requirement as test index in the test, the mathematical model of the smashing capability and power consumption is established. Along with the feeding velocity increase, the shell angle increase and distances of rotatory blade and fixed blade reducing, the smashing power loss increases, and the smashing performance enhances. Using the regression equations and the priority target law, the parameter optimized design has been carried on. The result is as follows . the shell angle is 70°, the feeding velocity is 46. 5 m/s, the distance of rotatory blade and fixed blade is 10 mm.
