具体实施方式
下面将结合本申请实现方式中的附图，对本申请实现方式中的技术方案进行清楚、完整地描述，显然，所描述的实现方式仅是本申请一部分实现方式，而不是全部的实现方式。
请参阅图1，图1为本申请的一个实施例提供的农机100的示意图。可以理解，农机100用于进行农作物种植或收割作业。举例说明，农机100可以是谷物联合收割机(Combine Harvester)，谷物联合收割机为一种可以一次实现谷类农作物的收割、脱谷、卸粮等工序，从而从田间直接获取谷粒的收获机械。
本实施例中，农机100可以包括机身10、作业机构20、驱动机构30和离合设备200。机身10是可在电力驱动下移动。作业机构20、驱动机构30和离合设备200安装在机身10上，作业机构20用于对农作物进行收割、脱骨和/或卸粮等。驱动机构30用于在电力驱动下产生用于驱动作业机构20工作的动力。离合设备200与作业机构20及驱动机构30可分离地连接，即作业机构20与驱动机构30通过离合设备200实现可分离地连接。离合设备200用于将驱动机构30产生的动力传递至作业机构20，以驱动作业机构20工作。离合设备200还用于停止驱动机构30对作业机构20的动力传递，以停止作业机构20的工作。
可以理解，农机100可以包括多个作业机构20和多个驱动机构30。多个作业机构20可以实现对农作物不同的作业功能，例如收割功能、脱谷功能、卸粮功能等，多个驱动机构30分别用于驱动对应的作业机构20工作。
请一并参阅图2及图3，本实施例中，离合设备200可以包括离合机构40和离合控制装置300。离合机构40用于连接驱动机构30和作业机构20，以将驱动机构30产生的动力传递至作业机构20。
离合控制装置300与离合机构40连接，离合控制装置300用于控制离合机构40进入结合状态或分离状态。其中，当离合机构40处于结合状态时，驱动机构30工作产生的动力可以传递至作业机构20，作业机构20可以对农作物进行收割、脱谷或卸粮作业。当离合机构40处于分离状态时，驱动机构30工作产生的动力无法传递至作业机构20，作业机构20停止工作。也就是说，离合控制装置300通过控制离合机构40切换结合状态与分离状态，可以控制作业机构 20的工作与停止。
本实施例中，离合机构40可以包括张紧组件41和传动带42。驱动机构30可以包括主动轮31。作业机构20可以包括从动轮21。传动带42绕设于主动轮31与从动轮21。张紧组件41可以包括连接件412和张紧轮411。连接件412可以转动连接于机身10。张紧轮411可以转动连接在连接件412上。张紧轮411转动的圆心与连接件412转动的圆心间隔设置，连接件412的转动可以带动张紧轮411沿相同圆周方向转动，从而改变张紧轮411与传动带42之间的距离，即张紧轮411随连接件412同步转动可以压紧或松开传动带42。
可以理解，如图3所示，当离合机构40处于结合状态，例如张紧轮411压紧传动带42从而使传动带42张紧时，传动带42与主动轮31、从动轮21紧密贴合。此时，主动轮31转动可以带动从动轮21转动，进而将驱动机构30的动力传递至作业机构20，作业机构20工作。
如图2所示，当离合机构40处于分离状态，例如张紧轮411松开传动带42从而使传动带42松弛时，传动带42与主动轮31、从动轮21之间的静摩擦力减少。此时，主动轮31的转动无法带动从动轮21同步转动，作业机构20停止工作。
本实施例中，离合控制装置300可以包括连接绳50、驱动组件60和处理器70，连接绳50可以为在外力作用下形变的硬质绳体，连接绳50一端与连接件412连接，另一端与驱动组件60连接。处理器70与驱动组件60通信连接，处理器70用于控制驱动组件60驱动连接绳50移动，带动连接件412同步转动。如此，连接件412的同步转动将控制张紧轮411压紧或松开传动带42。
可以理解，通信连接可以是通过电线实现的有线通信连接，还可以是通过通信装置实现的无线通信连接，本申请的实施例对此不作限定。
可以理解，连接绳50可以是具有形变能力的金属线缆，且材质可以是但不局限于铁合金、铜合金等。
可以理解，本申请的实施例对连接绳50、驱动组件60和张紧组件41的位置关系不作限定，仅需确保在驱动组件60驱动连接绳50移动时，根据连接绳50、驱动组件60和张紧组件41的位置关系，连接绳50可以发生弹性形变，例如驱动组件60驱动连接绳50移动时，由于驱动组件60和张紧组件41位于不同平面上，或由于机身10内其他部件阻隔在驱动组件60和张紧组件41之间， 连接绳50的部分部位可以发生弯曲。
可以理解，当农机100上设有多个作业机构20、多个驱动机构30和多个离合机构40时，农机100上可以对应设置多个离合控制装置300。每一离合控制装置300用以分别控制对应的离合机构40切换分离状态或结合状态。
可以理解，在其他实施例中，当农机上设有多个作业机构20和多个驱动机构30时，农机100上也可以仅设置一个离合控制装置300。离合控制装置300可以包括多个连接绳50和多个驱动组件60。每一连接绳50对应一个离合机构40。其中，每一驱动组件60用于驱动对应的连接绳50移动，进而通过对应的连接绳50控制对应的离合机构40切换分离状态或结合状态。
可以理解，在本申请的实施例中，并不对连接绳50与连接件412之间的连接关系进行限定。例如，连接绳50一端通过一转动连接工件与连接件412铰接。转动连接工件可以是，但不局限于，铰链、销轴等。
又例如，如图2所示，连接绳50与连接件412之间连接缓冲件51，缓冲件51两端分别与连接绳50、连接件412转动连接。
可以理解，当张紧轮411压紧传动带42时，传动带42发生弹性形变并产生弹力，形成对张紧轮411的反作用力。农机100进行农业生产作业时，由于机身10行进过程中发生的晃动，作业机构20、驱动机构30工作时发生的振动，和/或传动带42发生弹性形变产生的弹力，张紧的传动带42存在推动张紧轮411运动的趋势。如此，通过设置缓冲件51，可以有效缓冲传动带42对张紧轮411的弹力，减少连接绳50在反作用力冲击下被拉动而使张紧轮411松开传动带42的可能性。
可以理解，在本申请的实施例中，缓冲件51可以是但不局限于弹簧。
可以理解，缓冲件51可以通过转动连接工件实现与连接绳50、连接件412连接，转动连接工件可以是但不局限于铰链、销轴等。
可以理解，如图2所示，在本申请的实施例中，离合控制装置300还可以包括箱体80。驱动组件60收容于箱体80中。箱体80上开设有通孔81，通孔81连通箱体80的内部和外部，连接绳50穿设于通孔81，连接绳50与驱动组件60连接的部分通过通孔81进入箱体80。
可以理解，箱体80用于对驱动组件60进行保护，同时对连接绳50与驱动组件60的连接点631进行保护。
请参阅图4，一些实施例中，驱动组件60可以包括驱动件61及传动组件。连接绳50一端连接于传动组件。驱动件61与处理器70通信连接。驱动件61用于在处理器70的控制下驱动传动组件运动，带动连接绳50同步运动。
一些实施例中，传动组件可以包括第一传动件62和第二传动件63。第一传动件62与第二传动件63可相对运动地连接。第一传动件62、第二传动件63可以是齿轮，驱动件61可以是减速电机，第一传动件62、第二传动件63均转动连接于箱体80内壁，驱动件61固定安装于箱体80内壁。驱动件61可以在处理器70的控制下驱动第一传动件62运动，第一传动件62带动第二传动件63及连接绳50同步运动。
可以理解，可相对地运动可以包括可相对地移动(例如直线移动)，还可以包括可相对地转动，本申请的实施例对此不作限定。
本实施例中，第一传动件62的圆心与第二传动件63的圆心之间存在间隔。第一传动件62同轴固定于驱动件61的输出端，第二传动件63与第一传动件62啮合，连接绳50铰接于第二传动件63上，且连接绳50在第二传动件63上的连接点631与第二传动件63的圆心间隔设置。
可以理解，第二传动件63上除圆心外，其他部位与通孔81之间的直线距离可以随着第二传动件63的转动而改变。也就是说，当第二传动件63转动时，可以改变连接点631与通孔81之间的直线距离，即改变连接绳50进入箱体80的长度。例如，当第二传动件63通过转动增加连接绳50进入箱体80的长度时，连接绳50在箱体80外的长度减少，第二传动件63可以拉动连接绳50移动，进而带动连接件412转动，使张紧轮411压紧传动带42，离合机构40进入结合状态。又例如，当第二传动件63通过转动减少连接绳50进入箱体80的长度时，连接绳50在箱体80外的长度增加，传动带42通过张紧时产生的弹力推动张紧轮411，从而使张紧轮411松开传动带42，离合机构40进入分离状态。
可以理解，在本申请的实施例中，第一传动件62和第二传动件63可以是完整齿轮，也可以是不完整齿轮，本申请的实施例对此不作限定。
可以理解，在本申请的实施例中，第一传动件62、第二传动件63分别与箱体80内壁的转动连接方式，和/或连接绳50与第二传动件63的铰接反格式进行限定。例如，第一传动件62、第二传动件63与箱体80内壁的转动连接，和/或连接绳50与第二传动件63的铰接均可以通过转动连接工件实现。转动连接工 件可以包括但不局限于销轴、轴承等。又例如，请参阅图4和图5，一些实施例中，第二传动件63与连接绳50一端可以通过连接轴52实现转动连接。具体地，连接绳50一端与连接轴52固定连接，连接轴52穿设于第二传动件63并与第二传动件63转动连接。箱体80内壁上可以开设有滑槽82，连接轴52一端收容于滑槽82，连接轴52与滑槽82沿第二传动件63的转动方向滑动连接。
可以理解，滑槽82的设置可有效加强对连接轴52运动轨迹的限定，并进一步提高连接轴52运动的稳定性。
可以理解，连接绳50可以绕设或穿设于连接轴52，以实现连接绳50与连接轴52的固定连接。
可以理解，请再次参阅图4，本申请实施例中，离合控制装置300还包括接触开关90。接触开关90安装于箱体80内。接触开关90可以是通过抵触触发的电子开关，可以是但不局限于微动开关、行程开关等。
可以理解，在本申请实施例中，第二传动件63可以包括主体632和抵持部633。主体632与抵持部633一体连接，主体632与箱体80内壁转动连接，抵持部633可以转动至与接触开关90抵持，以触发接触开关90。具体地，接触开关90可以包括第一开关91和第二开关92。第一开关91和第二开关92可以固定安装于箱体80内壁上。第一开关91和第二开关92沿圆周方向间隔设置。驱动件61可以驱动第二传动件63转动，使抵持部633转动并与第一开关91或第二开关92抵持，以触发第一开关91或第二开关92。其中，当抵持部633沿第二开关92朝向第一开关91的方向运动，并与第一开关91抵持时，离合机构40处于结合状态；当抵持部633沿第一开关91朝向第二开关92的方向运动，并与第二开关92抵持时，离合机构40处于分离状态。
可以理解，本实施例中，主体632可以是不完整齿轮，主体632的不完整部位上沿主体632的直径方向延伸形成抵持部633。
可以理解，本申请的实施例对连接点631在第二传动件63上的位置不作限定。例如，如图4所示，连接点631也可以位于抵持部633上。
本实施例中，第一开关91和第二开关92可以沿以主体632圆心为圆心的圆周方向间隔设置。
本实施例中，滑槽82的可以是以主体632的圆心为圆心的圆弧槽，滑槽82的开设长度可以对应于沿第一开关91与主体632圆心的连线，及第二开关92 与主体632圆心连线所形成的夹角角度。
可以理解，通过间隔设置的第一开关91和第二开关92，以及滑槽82可以限定第二传动件63的转动行程，避免第二传动件63的转动角度过大或过小导致对传动带42的过度按压或传动带42张紧程度不足，减少传动带42受损或驱动机构30传递给作业机构20的动力损失过多的情况。
可以理解，在本申请的实施例中，接触开关90与处理器70通信连接。处理器70可以确定接触开关90是否触发，并在接触开关90触发时控制驱动件61停止工作。例如，当确定第一开关91或第二开关92触发时，处理器70控制驱动件61停止工作。
可以理解，连接点631与主体632的圆心的连线，及通孔81的中心与主体632的圆心的连线形成连接夹角。例如，连接夹角可以是如图4中所示的α角。本实施例中，驱动件61驱动抵持部633沿第二开关92朝向第一开关91的方向运动，以调整连接夹角，使连接夹角达到预设角度。
可以理解，预设角度可以对应于当连接点631对于主体632圆心的力臂达到最小或接近最小时的角度。当连接点631对于主体632圆心的力臂达到最小时，驱动件61的输出端所承受的来自连接绳50反作用力达到最小或接近达到最小，可以加强对驱动件61的保护。
一种实现方式中，第一开关91与第二传动件63圆心的连线，及第二开关92与第二传动件63圆心连线所形成的夹角为直角。滑槽82为一与主体632的圆心为圆心的四分之一圆弧槽。滑槽82远离第二开关92的一端与主体632的圆心及通孔81中心位于一条直线上。当抵持部633转动至使连接轴52运动至滑槽82远离第二开关92的一端时，抵持部633与第一开关91抵持时，处理器70控制驱动件61停止工作，以停止抵持部633的转动。在该实现方式中，第二传动件63的最大可转动角度为90度，预设角度可以是180度，连接夹角的角度可以从90度调整至180度。
可以理解，在本申请实施例中，第二传动件63的圆心对应通孔81设置，且当抵持部633与第一开关91抵持时，即连接夹角达到预设角度时，连接点631与通孔81的连线经过第二传动件63的圆心。即连接点631、第二传动件63的圆心及通孔81三点的连线为直线。此时，连接绳50位于箱体80内的部位张紧且与连接点631、第二传动件63的圆心及通孔81三点的连线重合，连接点631 与通孔81之间的直线距离达到最大，连接绳50位于箱体80内的长度达到最大。此时，连接点631的位置达到死点位置，驱动件61的输出端所承受的反作用力达到最小。
另一种实现方式中，第一开关91与第二传动件63圆心的连线，及第二开关92与第二传动件63圆心连线所形成的夹角为角度略大于90度的钝角，例如为95度角。滑槽82为一与主体632的圆心为圆心且接近四分之一圆弧槽。滑槽82远离第二开关92的一端与通孔81中心的连线接近于主体632的圆心，且位于主体632圆心远离第二开关92的一侧。在该实现方式中，第二传动件63的最大可转动角度为95度，预设角度可以是185度，连接夹角的角度可以从90度调整至185度。
可以理解，当抵持部633与第一开关91抵持时，即连接夹角达到预设角度时，连接点631与通孔81的连线接近经过第二传动件63的圆心，且位于第二传动件63圆心远离第二开关92的一侧。此时，连接点631的位置达到的位置接近于死点位置，驱动件61的输出端所承受的反作用力接近达到最小。此时，在来自连接绳50的反作用力下，抵持部633仅存在向远离第二开关92的方向转动的趋势，且滑槽82远离第二开关92的一端限制了连接轴52向远离第二开关92的方向的运动，即限制了抵持部633向远离第二开关92的方向转动。
可以理解，请参阅图3和图4，当离合机构40处于结合状态、张紧轮411压紧传动带42时，连接点631位于第二传动件63圆心远离通孔81的一侧，且连接点631、第二传动件63的圆心及通孔81中心三点的连线为一直线或接近于一直线。当张紧轮411由于传动带42形变产生的弹力推动而出现向远离传动带42的方向移动的趋势时，连接件412存在发生转动并拉动连接绳50的趋势。此时由于连接绳50位于箱体80内的部位与连接点631、第二传动件63的圆心及通孔81中心三点的连线或接近重合，连接件412对连接绳50的牵引力所在方向与连接绳50在箱体80内的部分的长度方向相同或接近相同，连接点631朝向第二传动件63圆心的方向与连接点631朝向通孔81中心的方向相同或接近相同，此时在第二传动件63上受到在第二传动件63的圆弧相切的方向上的分力可以为0或接近于0，从而减少第二传动件63在连接绳50的拉动下转动的概率，以及减少张紧轮411、连接件412在传动带42弹力作用下的转动的概率，使张紧轮411可持续地压紧传动带42以持续维持离合机构40的结合状态。
可以理解，请再次参阅图2及图3，在一些实施例中，离合控制装置300还可以包括交互组件110。交互组件110与处理器70通信连接。交互组件110用于响应操作人员的操作，并输出触发指令给处理器70。处理器70响应于触发指令可以控制驱动件61工作。
可以理解，交互组件110可以是具有人机交互功能的电子装置，操作人员对交互组件110的操作可以是在交互组件110上手动实现的，也可以是操作人员通过在其他终端设备上手动操作，使其他终端设备向交互组件110发送指令实现的。
一些实施例中，交互组件110可以包括远程操作件111和实体操作件112，远程操作件111可以与处理器70通过通信装置实现无线通信连接，实体操作件112可以固定安装在机身10上，并与处理器70通过数据线实现有线通信连接。操作人员可以在操作机身10时通过操作实体操作件112向处理器70输出触发指令，也可以通过操作远程操作件111在远端向处理器70输出触发指令。
可以理解，实体操作件112可以是机身10上的操作面板；远程操作件111可以是具有无线通信功能的电子装置，包括但不局限于智能手机、遥控器、电脑等。
请参阅图2和图3，一些实施例中，离合控制装置300还可以包括存储器120。存储器120用于存储农机100的车辆信息，包括转速、车速、故障信息等。处理器70与存储器120通信连接。当处理器70接收触发指令后，处理器70可以从存储器120获取车辆信息，并根据车辆信息确定农机100是否存在异常。当处理器70确定农机100存在异常时，处理器70针对触发指令不作响应。当处理器70确定农机100不存在异常时，处理器70可以根据触发指令控制离合机构40工作。例如，处理器70可以读取车辆信息中的转速、车速等参数，并确定参数是否超出预设的阈值范围，从而确定农机100是否异常。又例如，处理器70可以读取车辆信息中是否存在故障信息，进而直接判断农机100是否异常。
一些实施例中，车辆信息还包括离合机构40的状态。如此，处理器70在确定农机100不存在异常时，可以再确定车辆信息是否符合预设条件。当车辆信息符合预设条件时，处理器70可以控制驱动件61工作以驱动连接绳50移动；当车辆信息不符合预设条件时，处理器70可以不作响应。
可以理解，当农机100具有多个作业机构20和多个离合机构40，触发指令可以是针对多个作业机构20中的一个作业机构20及其相应的离合机构40。预设条件可以有多个，多个预设条件与多个不同的触发指令一一对应。预设条件可以是多个离合机构40中，指定一个或多个离合机构40处于结合状态或分离状态。
可以理解，农机100工作时，农机100上的多个作业机构20需根据指定的流程依次启动、工作，或在指定的一个或多个作业机构20启动及工作时，部分作业机构20须根据指定的作业要求维持关闭状态；由于作业机构20工作所需的动力由离合机构40传递，因此处理器70可以在接收触发指令时，通过确定多个离合机构40的状态进而确定触发指令所对应的对指定离合机构40的操作是否可以进行。
例如，请一并参阅图6，多个作业机构20可以包括脱谷机构、收割机构和卸粮机构，对应的多个离合机构40可以包括脱谷离合、收割离合和卸粮离合，多个预设条件可以包括：
当需要控制脱谷离合结合时，需确定收割离合、脱谷离合均处于分离状态；
当需要控制脱谷离合分离时，需确定收割离合处于分离状态且脱谷离合处于结合状态；
当需要控制收割离合结合时，需确定脱谷离合处于结合状态且收割离合处于分离状态；
当需要控制收割离合分离时，需确定收割离合处于结合状态；
当需要控制卸粮离合结合时，需确定脱谷离合、卸粮离合均处于分离状态；
当需要控制卸粮离合分离时，需确定卸粮离合处于结合状态。
以下结合图1至图6对本申请实施例提供的农机100的工作原理进行描述：
操作人员通过操作交互组件110向处理器70输出触发指令后，处理器70接收触发指令并获取车辆信息。
处理器70根据车辆信息判断农机100是否存在异常，并在农机100不存在异常时确定车辆信息是否符合与触发指令对应的预设条件。若车辆信息符合预设条件，则处理器70控制驱动件61工作。
如图3和图4所示，驱动件61工作可以驱动第一传动件62转动，带动第二传动件63同步转动，并带动连接绳50移动。当需要将离合机构40从分离状 态转换至结合状态时，驱动件61驱动抵持部633从第二开关92向第一开关91的方向转动，带动连接绳50同步移动。连接绳50拉动连接件412转动，从而使张紧轮411逐渐压紧传动带42。当抵持部633与第一开关91抵持时，处理器70确定第一开关91触发并控制驱动件61停止工作。此时连接绳50可以与连接点631、第二传动件63的圆心及通孔81所在连线重合，张紧轮411压紧传动带42，驱动机构30产生的动力传递至作业机构20，作业机构20工作。
如图2所示，当需要将离合机构40从结合状态转换至分离状态时，驱动件61驱动抵持部633从第一开关91向第二开关92的方向转动，带动连接绳50同步移动。张紧轮411逐渐松开传动带42。当抵持部633与第二开关92抵持时，处理器70确定第二开关92触发并控制驱动件61停止工作。此时，传动带42恢复松弛，驱动机构30产生的动力无法传递至作业机构20，作业机构20停止工作。
本申请的实施例中，通过设置驱动组件，可驱动张紧组件41运动，进而取代人工施力对张紧组件41的操作，降低了操作离合机构40时的人力损耗，同时提高了对离合机构40操控的方便性。
对于本领域技术人员而言，显然本申请不限于上述示范性实施例的细节，而且在不背离本申请的精神或基本特征的情况下，能够以其他的具体形式实现本申请。因此，无论从哪一点来看，均应将本申请上述的实施例看作是示范性的，而且是非限制性的，本申请的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化涵括在本申请内。
