输送与粉碎装置是青贮饲料收获机的两大核心工作部件,直接影响到机具的入料顺畅、作物切碎质量的好坏及功率消耗的大小。文中介绍了链耙式过桥输送装置以及立式Y型动刀揉切滚筒粉碎装置结构、工作原理及主要工作参数。试验表明,该结构输送性能强,揉切粉碎性能优良并且作业过程中不需要磨刀工序。 The conveying and comminuting unit is the two core working components of the silage harvester, which has a direct impact on the smooth feeding of the equipment, the quality of crop chopping and the power consumption. This paper introduces the structure, working principle and main working parameters of the chain rake bridge conveying device and the vertical Y-type knife cutting and rolling drum crushing device. Tests show that the structure of conveying performance, excellent kneading and crushing performance and the operation does not require sharpening process.
