Abstract

一种农用收割机,在收割机脱粒筒内的转动辊上,前面是螺旋叶片,后面是按螺旋线布置的V形击禾齿。筛盘通过吊杆和拐臂铰接在外壳罩上,拐臂下端还与转动轴固定。拐臂由转动轴带动作圆周运动,使筛盘一方面前后摆动,同时使筛盘后头上下摆动,于是将谷子筛下入谷盆、将草杆抛出收割机后。脱粒筒内的V形击禾齿,使脱粒干净,以筛盘的运动方式使谷粒与草杆分离,节省了动力。

Description

收割机
本实用新型涉及一种农用收割机。
现有的收割机,是将割下的禾杆,在脱粒筒里经旋转的螺旋叶片铰碎,使谷、杆脱离,夹杂大量碎屑的谷粒从谷斗落下,铰碎的谷杆通过风扇从侧面吹出。这种脱粒与输出方式,消耗动力大,落下的谷子不干净。
本实用新型的目的,是要提供一种消耗能量少,脱落的谷子较干净,谷粒、谷杆都通过筛盘输出的农用收割机。
下面结合附图及实施例介绍本实用新型。
图1为实用新型结构示意图。
参照附图,在收割机脱粒筒1内的转动辊2上,前面是螺旋叶片4,后面按螺旋线布置着用细圆钢条弯成的V形击禾齿3。筛盘8通过吊杆10和拐臂7铰接在外壳罩9上,拐臂比吊杆短很多。在筛盘8前头,吊杆10的上端铰接在外壳罩9上,下端铰接在筛盘上;在筛盘8后头,拐臂7的上端铰接在筛盘上,下端铰接在外壳罩上。拐臂下端与转动轴6固定。
旋转的螺旋叶片4,将收割机割下的禾杆带进脱粒筒,并进行部分脱粒,击禾齿3更有效地使谷粒干净脱落,草杆、谷粒都落入筛盘8。筛盘后头由拐臂7撑着,拐臂由转动轴6带动作圆周运动,使筛盘一方面前后摆动,同时使筛盘后头上下摆动,于是将谷子筛下落入谷盆5,并将脱粒后的草杆抛出收割机后。
脱粒筒内的V形击禾齿,能有效地干净脱粒;以筛盘的运动方式使谷粒与草杆分离,节省了动力。
