介绍了4ZTL—1800型割前摘脱稻(麦)联收机的板齿摘脱台与4ZT—400型板齿摘脱台的工作原理,通过对二者之间作业性能的比较看出采用气流吸运的板齿摘脱台在性能上优于带螺旋推动器和风扇的摘脱台,可以明显降低落粒损失和总损失。但后者有割幅大,工作效率高的优点,并且可与传统型联合收获机挂结,方便、经济。
This paper introduces the working principle of 4ZTL-1800 type pre-harvest rice (wheat) combined harvester and the 4ZT-400 plate-tooth removal station. By comparing the working performance between the two, The airflow pick-up plate removal station performs better than the pick-up station with screw pusher and fan, which can significantly reduce the droplet loss and total loss. However, the latter has the advantages of large cutting width and high work efficiency, and can be hung with a traditional combined harvester to be convenient and economical.
