具体地，各个部件传动路线以及传动连接关系的设置，便于部件之间的传动连接，减少传动路线中的损耗，提高收获机的稳定性以及可靠性，降低成本。
其中，作为皮带的可替换方案，可以根据实际需要通过链条、齿轮等进行传动。
如图1至图5所示，各轴流滚筒5的延伸方向与车体26的前后方向一致。
这样，一对轴流滚筒5的上述设置形成双纵轴流脱粒分离系统，满足大喂入量收获脱粒清选能力要求。
如图1至图5所示，风机6、籽粒升运器10、切碎器16、排草轮14、第一粮箱底搅龙27以及第二粮箱底搅龙28、筛箱驱动轴29的动力输入均来自分动箱22。
本申请实施例的谷物联合收割机可以为多功能谷物联合收割机，采用“喂入轮+双纵轴流”技术路线，喂入轮进行作物的辅助喂入和加速，提高喂入量情况下整机工作顺畅性，双纵轴流脱粒分离系统满足大喂入量作物脱粒分离要求。
在本实施例中，整机主传动采用集成传动箱结构，取消传统的皮带离合结构，简化传动，提高整机可靠性。
在本实施例中，采用“喂入轮+双纵轴流”的技术路线及主机集成传动方式。发动机21直联分动箱22，分动箱22五路输出，滚筒(轴流滚筒5)一路通过无级变速轮传到集成滚筒传动箱23。
在本实施例中，采用“喂入轮+双纵轴流”的技术路线，便于大型收获机械产品布置，提高收割机喂入量。主传动采用分动箱加集成滚筒传动箱方式，传动路线简单，可靠性高。
最后应说明的是：以上各实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述各实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围。
