图1和图2示出了依据本发明一种实施方式的谷物联合收割机的示意图。如图1所示，依据本发明的一种实施方式的纵轴流谷物联合收割机包括割台总成31，完成对农作物的扶持、切割、喂入。割台总成31下游设有过桥装置32，完成从割台总成31喂入的农作物的输送。过桥装置32下游设有脱粒分离装置36，完成对过桥装置32输送的农作物的脱粒、分离。脱粒分离装置36后部秸秆出口处右侧设置一弧板44，弧板44使从脱粒分离装置36排出的秸秆厚薄均匀地滑落到滑草板5上。滑草板5设置在该脱粒分离装置36后端秸秆出口处，向下倾斜一定角度。滑草板5下游设置有茎杆切碎抛撒装置47，滑草板5尾端延伸到茎杆切碎抛撒装置47的定刀与动刀重叠部分的上部，并与动刀旋转直径及定刀上端保证一定安全距离，把从脱粒分离装置36排出的茎杆顺畅滑送到茎杆切碎抛撒装置47进行切碎、抛撒、还田。茎杆切碎抛撒装置47的旋转驱动力由安装于清选装置装配结构45后下端的传动装置46的后传动轴9上的皮带轮10通过传动带6传递给切碎抛撒装置47的旋转轴皮带轮2。清选装置装配结构45用于安装清选装置等部件。
另外，脱粒分离装置36下方设有对籽粒、颖糠、碎茎秆、杂余等脱下物 进行清选的清选装置38。清选装置38下方设有对干净籽粒进行推运收集的籽粒推运装置39，所述籽粒推运装置39右端出口连接有籽粒升运装置65。籽粒升运装置65向前上方穿越粮箱后侧壁后，出口与粮箱37顶部顶搅龙(未示出)连接，这样，干净籽粒经籽粒升运装置输送到粮箱37，仓满后卸粮。在清选装置38下方、籽粒推运装置39后，设置有杂余收集输送装置40，杂余收集输送装置40把未脱净的穗头等推运收集后输送到脱粒分离装置36进行二次脱粒，然后清选。脱粒分离装置36左右两侧固定在清选装置装配结构45上，清选装置装配结构45包括清选室4。清选装置装配结构45下部设置有前桥机架装配结构35，前桥机架装配结构35后下部设置有转向桥装配结构43。清选装置装配结构45前上端设置有驾驶台33，驾驶台33上设置有驾驶室34，驾驶室34可通过紧固螺栓固定在驾驶台33上部，驾驶室34内设置有操纵装置，用于完成整机的各种操纵。驾驶室34后部依次设置有粮箱37、动力系统41、液压系统42。根据一种实施方式，粮箱37前部与驾驶室34用螺栓固定在一起，下端通过紧固螺栓固定在清选装置装配结构45的上部。清选装置装配结构45左后侧设置有燃油系统48。根据一种实施方式，燃油系统48可由燃油箱、电子输油泵及连接管路组成，燃油箱通过支架固定在清选室左后方，电子输油泵位于燃油箱前下方，连接管路把燃油箱中燃油输送给发动机。根据一种实施方式，滚筒调速装置49包括支撑结构及链轮，安装在清选装置装配结构左后侧壁上，辅助实现滚筒的无级调速，来满足不同作物的收获。
图3示出了依据本发明一种实施方式的脱粒分离装置的示意图，图4示出了图3所示的依据本发明一种实施方式的脱粒分离装置的示意横切剖视图。如图3和图4所示，依据本发明的一种实施方式的脱粒分离装置36包括凹板固定梁26，所述凹板固定梁为一由型钢组成的矩形结构，左右两侧通过紧固螺栓 固定在清选室4的壳体的左右侧壁上。脱粒分离装置36还包括纵轴流脱粒滚筒23(根据上下文，有时简称为滚筒或脱粒滚筒)，纵轴流脱粒滚筒23具有滚筒轴，纵轴流脱粒滚筒23通过滚筒轴前端支撑在固定梁前横梁轴承20上，滚筒轴后端通过紧固螺栓固定在联轴器22上。联轴器22通过花键套与滚筒换向箱21花键轴联接在一起，纵轴流脱粒滚筒23转动所需动力通过外部传动轴传递给滚筒换向箱21，再由滚筒换向箱21的输出轴传递给联轴器22而带动纵轴流脱粒滚筒23旋转。纵轴流脱粒滚筒23具有脱粒元件，可以采用现在已知的和未来已知的各种脱粒元件。根据一种实施方式，滚筒23的脱粒元件可以为“钉齿+杆齿”组合式，并呈锥形单螺旋线排列。这种方式的脱粒元件脱粒完全、分离彻底，并可实现对多种作物的脱粒分离(具体的详细内容可见CN201610941478.3，一种免维护型多功能纵轴流脱粒分离滚筒，该专利申请通过引用并入本文中，如同在本文中详细说明了一样)。滚筒23的脱粒元件也可以采用现有的其他方式实现。脱粒分离装置36还包括滚筒23上部的滚筒上罩24，滚筒上罩24的横截面成梯形或圆弧形结构，上罩内侧安装或焊接有与滚筒轴成一角度、径向一定高度的导草板66，导草板与滚筒23的滚筒轴的角度可调，从而可实现对不同作物或不同成熟度作物的分离(详见CN201620627435.3，一种收割机脱粒室的滚筒盖，通过引用将该中国专利申请的全部内容并入本文中，如同在本文进行了详细阐述一样)。脱粒分离装置36还包括在滚筒23的下部的脱粒凹板25。如图4所示，在脱粒凹板25的两侧上部有若干个垂直方向的长孔(凹板孔)。长孔的长度(纵向高度)L与清选室壳体左右侧壁上长孔(壁孔)的长度(纵向高度)A相对应，确保脱粒滚筒23与脱粒凹板25之间间隙H在设计范围内。在一种实施方式中，壁孔的在上下方向上的长度A等于凹板孔的长度L。脱粒分离装置36还包括凹板支撑轴29， 所述脱粒凹板25通过凹板孔L挂接在凹板支撑轴29上，凹板支撑轴29穿过固定梁26左右侧壁连接孔，经螺母紧固后固定在固定梁26上。凹板孔是本发明的凹板连接部的实施例，凹板支撑轴29是本发明的固定梁连接部的实施例，本领域技术人员可以想到各种的使脱粒凹板25能够相对于固定梁26可上下移动地连接的各种实施方式。
脱粒凹板25与脱粒滚筒23之间的间隙通过凹板调节装置而实现无级可调。根据一种实施方式，凹板调节装置包括凹板连接装置28和上下调节装置62。根据一种实施方式，该上下调节装置62是调节螺杆。图5是凹板调节装置实现脱粒凹板25与脱粒滚筒23之间的间隙的无极可调的局部放大示意图。如图3到图5所示，凹板连接装置28通过若干个固定螺栓64与脱粒凹板25固定在一起，并穿过清选室壳体侧壁的孔(壁孔)与上下调节装置62相连接。上下调节装置62下端与凹板调节装置28相连接，上端固定在清选室壳体上，上下调节装置62在该壳体上的位置可以调节。在上下调节装置62是调节螺杆的情况下，其可以穿过清选室壳体侧壁上的固定座上的孔(座孔)。此时，可以通过调节锁紧螺母63来调节该调节螺杆在固定在该座孔中的位置。用锁紧螺母63调节间隙H大小时，首先松开锁紧螺母63，根据需要上下移动调节螺杆62，调节螺杆62带动凹板连接装置28，并进而带动脱粒凹板25一起沿垂直方向上下移动，完成脱粒凹板与脱粒滚筒间隙H的无级可调，从而实现对不同农作物的收获或对不同成熟度作物的收获。脱粒分离装置36还包括杂余筒支撑结构27，所述杂余筒支撑结构27可位于滚筒上罩24左前部，通过螺栓固定在滚筒上罩24上，用于杂余收集输送装置的支撑。
回到图3，并参见图1，脱粒分离装置36还包括喂入板30，喂入板30位于滚筒23的前下部、脱粒凹板25的前部，上端的左右两侧可固定在固定梁26 前下侧，与滚筒23的喂入螺旋叶片、滚筒上罩24前部围成一特定空间，使从过桥结构输送来的作物顺利喂入并完成向后输送后得到充分脱粒、分离。
图6示出了依据本发明一种实施方式的茎杆切碎抛撒装置的示意图。如图1和图6所示，茎杆切碎抛撒装置47通过N个紧固螺栓3固定在清选室4的壳体的后尾部，并与清选装置38的清选尾筛7保证一定距离，确保尾筛维修空间。滑草板5安装在脱粒分离装置36的滚筒排草轮8下端与茎杆切碎抛撒装置47之间，滑草板5与水平面成一定角度，且上端前后方向与滚筒排草轮8前端平齐、并搭装在传动装置46的传动轴上方，并与传动轴确保一定距离。下端位于茎杆切碎抛撒装置47的动刀与定刀之间，并与动刀旋转直径保持一定距离。由此，脱粒后的茎杆经滚筒排草轮排出后滑落到滑草板5表面，沿滑草板5表面顺利下滑到茎杆切碎抛撒装置47的动刀与定刀之间被切碎、抛撒。
茎杆切碎抛撒装置对茎杆的切碎长度、抛撒宽度可调，以满足不同用户需求。如图6所示，手柄固定螺栓55用于将调节手柄56固定在茎杆切碎抛撒装置的机体上，如机壳或机架上。调节手柄与定刀53固定连接。茎杆切碎长度由定刀53与动刀54前后重叠量的大小确定。重叠量大，茎杆切碎长度短；重叠量小，茎杆切碎长度长。该重叠量可以调节，调节时，如图6所示，首先松开调节手柄固定螺栓55，再前后扳动调节手柄56，调节手柄56带动定刀53旋转，从而改变定刀53与动刀54的径向重叠量大小，达到调节茎杆切碎长度的目的，最后再拧紧调节手柄固定螺栓55。向后扳动调节手柄56，定刀逆时针转动，与动刀径向重叠量减小，茎杆切碎长度加长；向前扳动调节手柄56，定刀顺时针旋转，与动刀径向重叠量加大，茎杆切碎长度减小。用户可根据需要进行调节。尽管图中示出为调节手柄带动定刀旋转，但是本领域技术人员应该可以清楚，根据不同的实施例，调节手柄56可以推动定刀前后移动。另外，依据本发明的一种实施方式的茎杆切碎 抛撒装置47对切碎后茎杆抛撒宽度可调。如图6所示，对茎杆的抛撒宽度由抛撒板50尾部(抛撒板后端)散开宽度确定。尾部向两端散开，切碎后的茎杆沿抛撒板抛撒面抛出后，抛撒地面宽，堆积薄，还田效果好。调整时，如图6所示，松开螺栓52及螺栓51，移动抛撒板50尾部在其固定板67上的横向长槽68内位置可实现抛撒宽度的调整,以满足用户要求，最后拧紧螺栓52及螺栓51即可。螺栓52和51分别位于抛撒板50的底部和与横向长槽68的对应处，用于将抛撒板固定在固定板67上，螺栓52和51是本发明的调节装置的示例，可以想到其他的使抛撒板50得散开宽度变化的各种实施方式。尽管图中示出了6个抛撒板50，但是本领域的技术人员应该意识到，可以有更多的或少些的抛撒板和对应的横向长槽68。
本发明的上述详细的描述仅仅用于向本领域技术人员提供更进一步的详细内容，以用于实施本发明的优选方面，不是对本发明的范围进行限制。仅有权利要求用于确定本发明的保护范围。为了获得本发明的附加的实用实施例，在说明书中给出教导的各种不同的特征可通过多种方式结合，这些结合都在本发明的保护范围内。
