STRAW CHOPPER MOUNTING FOR COMBINE 聯(lián)合秸稈粉碎還田器的安裝 This invention relates to an improved means for mounting a straw chopper on a combine 本發(fā)明涉及一種改進(jìn)的手段 即在聯(lián)合收割機上安裝秸稈粉碎還田機 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 當(dāng)玉米或作物殘留物很厚時 用聯(lián)合收割機進(jìn)行秸稈粉碎還田以減少作物 殘留物 然后才鋪散開 這樣這些殘留物以后就不會造成耕作問題 然而 在 一些作物條件下 秸稈粉碎還田機是不需要的 甚至也不理想 在這種情況下 在過去這種情況的處理方法是去除聯(lián)合秸稈粉碎還田機 這是一件單調(diào)乏味的 工作 因為秸稈粉碎機很重而且一個人并不能使笨重的附件相互依附或分離開 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 本發(fā)明設(shè)想提供在聯(lián)合收割機傳統(tǒng)位置上安裝一個秸稈粉碎還田器 的手段 這將不會干擾玉米等秸稈從機架中排出 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 本發(fā)明的進(jìn)一步目標(biāo)是提供一個安裝秸稈粉碎還田機的手段 使斬波器可 以保持在任何時候都可以安裝在聯(lián)合收割機上 但當(dāng)這樣安裝時 一個人就可 以從一個執(zhí)行秸稈粉碎的位置轉(zhuǎn)移到其對立的位置上 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 在具有縱向延伸秸稈架結(jié)合位置 一個遮光罩定位在秸稈架末端 上述遮 光罩由架空和結(jié)束部分加入的縱向延伸反向側(cè)墻提供 這一改進(jìn)包括一個縱向 延伸第一個通道 它與上述側(cè)墻的每一面相連接 秸稈粉碎還田器有縱向延伸 的第二通道 它連接到側(cè)墻的每一面并且加以補充與第一個渠道附件連接 這 樣秸稈粉碎還田器從上述遮光罩得到支持 而遮光罩通過上述第一和第二渠道 附件之間的嵌套合作得以實現(xiàn) 秸稈粉碎還田器的可滑動式安裝使其可沿著第 一渠道附件縱向運動 以保留在接受有關(guān)從秸稈架解除第一個位置上的秸稈粉 碎還田器和相對于解除秸稈架末端前方對立位置的秸稈粉碎還田器為手段
