Abstract

一种玉米收获机卸粮装置，由导向板和导向板稳定弹簧等组成。它可以将玉米收获机收获的果穗，导入果穗箱或运粮车中。在玉米收获机开地头或开始进入玉米地作业时，导向板倾斜于果穗箱方向，所摘玉米果穗流入果穗箱。当玉米收获机进入正常作业时，运粮车与玉米收获机平行同步运行，翻转导向板，使之向运粮车方向倾斜，玉米果穗即流入运粮车中。当运粮车装满时，再翻转导向板，使之倾斜于果穗箱。导向板稳定弹簧和导向板导轨槽使导向板可靠地位于两个倾斜工作位置，保证了双向导穗装置可靠地工作。该装置结构简单，性能可靠。

Description

一种玉米收获机卸粮装置
技术领域
本实用新型属于农业机械，特别是涉及玉米收获机的卸粮装置。
背景技术
现有的玉米收获机在作业时，玉米经过割台摘穗后果穗由升运器提升至果穗箱。在升运器的后端安装卸粮装置，该卸粮装置是由安装有倾斜导流板的导槽构成。果穗经过该卸粮装置流入果穗箱。现有的卸粮装置是单方向卸粮的，是使果穗向果穗箱方向单向流动的。果穗箱装满后再倒入运粮车。每次卸粮时玉米收获机必须停止作业。这样占用了作业时间，影响作业效率。又由于果穗流动性差，使果穗箱的容积得不到充分利用，所以必须有工人在果穗箱里，由人工摊均果穗。在果穗箱里面站人，劳动强度大，特别是存在安全隐患，不符合安全作业要求，是有关法规不允许的，一直是难以解决的问题。另外，经常出现果穗箱装满而运粮车还没有到，只好停机等待，或运粮车已到，而果穗箱还没有装满，运粮车也要等待。这也影响作业效率的发挥。
发明内容
本实用新型针对现有的玉米收获机卸粮装置存在的单向卸粮影响作业效率的问题，即本实用新型的目的是通过改变卸粮装置的结构实现双向卸粮。
本实用新型的目的是通过以下技术措施实现的：一种玉米收获机卸粮装置，其特点在于该装置是由导槽壳体、导向板、导向板轴和定位装置组成，可以双向翻转的导向板上有弧形导轨槽，导向板定轴在弧形导轨槽内，导向板安装在导向槽壳体内，由定位装置使导向板稳定在工作位置。定位装置是有稳定弹簧的一端挂在导向板弹簧挂接轴上，稳定弹簧的另一端与安装在壳体上的弹簧挂接轴挂接。
当玉米收获机正常作业时，运粮车可以与玉米收获机同步并行，这时把导向板翻转向运粮车一侧。运粮车装满离开时将导向板翻到果穗箱一侧，作为储备。导向板翻转方便自如。这样卸粮时不需要停机，大幅度提高作业效率。也不需要在果穗箱里面站人，解决了安全问题。
附图说明
图1是玉米收获机卸粮装置工作示意图。
图2是玉米收获机卸粮装置结构图。
图3是玉米收获机卸粮装置的另一种结构。
图4是玉米收获机卸粮装置右视图。
图5是卸粮装置导向板结构图。
具体实施方案
下面结合附图对本的实施方案做进一步说明。如图1所示的玉米收获机卸粮装置工作示意图。当玉米收获机在开地头或作业开始时卸粮装置导向板2倾斜向果穗箱3，玉米果穗5沿导向板2流向果穗箱3。在正常作业时，运粮车4与玉米收获机并行同步运行，这时如图2、3将导向板2转向运粮车4方向倾斜。果穗就沿导向板2流向运粮车4。见图5，导向板2上有弧形导轨槽10，在弧形导轨槽的对称中心线上有导向板弹簧挂接轴7，在导轨槽10内有导向板定轴6。见图2、3、4，导向板稳定弹簧8的一端挂接在导向板挂接轴7上，导向板稳定弹簧8的另一端挂在与壳体联接的壳体弹簧挂接轴9上，导向板定轴6和壳体弹簧挂接轴9在壳体的对称面上。弧形导轨槽10的对称中心线上有导向板弹簧挂接轴7。在卸粮状态转换时，转动导向板2导向板定轴6在弧形导轨槽10内滑动，带动导向板稳定弹簧8以壳体弹簧挂接轴9为圆心转过一个角度，在导向板稳定弹簧8拉力的作用下使导向板2在新的倾斜位置稳定地定位。导向板2的转动可通过绳索或推拉杆由驾驶员在下面操控，即可保证双向卸粮装置可靠地工作。这一卸粮装置能完成双向卸粮，减少卸粮辅助时间，提高作业效率，节省果穗箱内工人，且消除了安全隐患。机构简单性能可靠，成本低。
