STRAW CHOPPER MOUNTING FOR COMBINE联合秸秆粉碎还田器的安装This invention relates to an improved means for mounting a straw chopper on a combine 本发明涉及一种改进的手段，即在联合收割机上安装秸秆粉碎还田机When the straw or crop residue is thick, a straw chopper is used on a combine harvester to reduce the crop residue before it is spread so that such residue does not later cause tillage problems. However, in some conditions of crops, a straw chopper is not required, nor even desired. Under such circumstances, in the past the way such situation was handled was to remove the straw chopper from the combine. This was a tedious task as straw choppers are heavy and bulky attachments which do not lend themselves to attachment or detachment from a combine by one man.当玉米或作物残留物很厚时，用联合收割机进行秸秆粉碎还田以减少作物残留物，然后才铺散开，这样这些残留物以后就不会造成耕作问题。然而，在一些作物条件下，秸秆粉碎还田机是不需要的，甚至也不理想。在这种情况下，在过去这种情况的处理方法是去除联合秸秆粉碎还田机。这是一件单调乏味的工作，因为秸秆粉碎机很重而且一个人并不能使笨重的附件相互依附或分离开。Accordingly, the present invention contemplates providing means on a combine for mounting a straw chopper in the conventional position on a combine harvester for chopping straw delivered thereto from the chopper will not interfere with the discharge of straw from such straw rack.因此，本发明设想提供在联合收割机传统位置上安装一个秸秆粉碎还田器的手段，这将不会干扰玉米等秸秆从机架中排出。A further object of this invention is to provide mounting means for a straw chopper so that such chopper can remain mounted on a combine harvester at all times, but such straw chopper while so mounted can be shifted by one man from an operative straw chopping position to a neutral out of the way position.本发明的进一步目标是提供一个安装秸秆粉碎还田机的手段，使斩波器可以保持在任何时候都可以安装在联合收割机上，但当这样安装时，一个人就可以从一个执行秸秆粉碎的位置转移到其对立的位置上。In a combine having a longitudinally extending straw rack, a hood positioned over the end of said straw rack, said hood being provided with longitudinally extending opposed side walls joined by an overhead and end portion, the improvement comprising a longitudinally extending first channel member attached to each of said side walls, a straw chopper having longitudinally extending second channel member attached to each side and being complementary to said first channel members so that said straw chopper is supported from said hood by means of a nesting coaction between said first and second channel members, said straw chopper being slidably mounted for longitudinal movement along said first channel members, means for retaining said straw chopper in a first position in receiving relation to straw discharged from said straw rack and for relating said straw chopper in a forward neutral position relative to said discharge end of said straw rack. 在具有纵向延伸秸秆架结合位置，一个遮光罩定位在秸秆架末端，上述遮光罩由架空和结束部分加入的纵向延伸反向侧墙提供，这一改进包括一个纵向延伸第一个通道，它与上述侧墙的每一面相连接，秸秆粉碎还田器有纵向延伸的第二通道，它连接到侧墙的每一面并且加以补充与第一个渠
