芦苇收割机结构设计(含CAD图纸)
本文设计了一种芦苇的多功能收割机械。这款多功能收割机采用65马力柴油机,首先采用链式拨禾装置把芦苇拨入收割台,采用了往复式收割器对芦苇进行收割,然后通过加持链条送入输送,随后送入立式滚筒打捆系统对芦苇进行打捆,打捆的芦苇最终掉入滚筒下的集料箱实现茎秆的收集,实现了芦苇的联合收割。芦苇多功能收割机的收割和拨禾装置是非常重要的,而且还要处理好前进速度和拨禾速度的关系,芦苇是比较硬的一种作物,所以在收割和拨禾过程中是其中的难点,不能像小麦那样的大的拨禾轮,而是采用了链式传动,链条上按放着长齿条,在工作时,不断运动把芦苇往割刀方向拨。 Abstract Korshi
