下面结合图1-图11描述本申请的作业运输机。
根据本申请的实施例，如图1-图3所示，本申请提供的作业运输机，主要包括：作业机械1和运输机3。其中，作业机械1包括上车体101和下车体， 上车体101和下车体通过第一回转机构2相连，下车体包括第一行走机构102；运输机3包括运输平台301和第二行走机构302，运输平台301连接于下车体的后端，且运输平台301的底部通过第二回转机构5与第二行走机构302相连；第一行走机构102和第二行走机构302分别设有行走驱动机构，第一行走机构102和第二行走机构302在行走驱动机构的驱动下行走。
可以理解的是，本申请作业机械1的上车体101与下车体可回转，并且运输机3的运输平台301与第二行走机构302可回转，前车作业机械1上车体101的转动不受后车运输机3影响，即运输机3不会影响作业机械1作业臂的活动，可以更好地进行各种作业。
本申请实施例提供的作业运输机，通过第一回转机构2，实现作业机械1上车体101和下车体的回转，通过将运输机3的运输平台301连接于作业机械1的下车体，作业机械1的上车体101可以360°自由回转作业，不受运输机3的影响，保证了作业的灵活性，通过第二回转机构5，实现运输平台301与第二行走机构302的回转，进而使后车运输机3的运输平台301可以跟随前车作业机械1转弯；并且在完成一次作业后，作业机械1的上车体101在进行作业(例如挖土)后可回转从而直接将作业物放置到运输机3上(如图2所示)，可以大大提高作业效率；并且作业机械1与运输机3均设有行走驱动机构，可以有效提高整体的动力性能，从而适应复杂多变的地形，具有使用方便、场地适应性强等特点。
在一个实施例中，第一回转机构2主要包括回转马达、行星齿轮减速器、第一回转支承和第一中央回转接头6。其中，回转马达和行星齿轮减速器固定于作业机械1下车体上，第一回转支承的外圈与上车体101的转台固定相连，第一回转支承的内圈与第一行走机构102的车架固定相连，回转马达经行星齿轮减速器与第一回转支承的内圈齿轮啮合，在回转马达的驱动下使上车体101相对于下车体产生回转运动；第一中央回转接头6设置于作业机械1上，第一中央回转接头6的壳体与上车体101的转台相连，第一中央回转接头6的芯轴与第一行走机构102的车架相连，实现作业机械1回转时的液压油路传输。
在一个实施例中，第二回转机构5包括第二回转支承和第二中央回转接头 9。其中，第二回转支承的外圈与运输平台301固定相连，第二回转支承的内圈与第二行走机构302的车架固定相连，当作业机械1的第一行走机构102转弯时，运输机3的运输平台301可以跟随作业机械1转弯，进而可以节省一套回转马达和行星齿轮减速器动力源；第二中央回转接头9设置于运输机3上，第二中央回转接头9的壳体与运输机3的运输平台301相连，第二中央回转接头9的芯轴与第二行走机构302的车架相连，实现运输机3回转时的液压油路传输。
可以理解的是，本申请前车作业机械1和后车运输机3同时设置了回转机构，作业机械1的第一回转机构2可以360°转动，运输机3也可以利用第二回转机构5进行水平方向的自由转动，并且运输机3的运输平台301在作业机械1第一行走机构102的带动下，可以进行相对转动，当前后车两部分在转弯时，合理控制第一行走机构102和第二行走机构302的行走，可以顺利完成较大角度的转弯。
根据本申请的实施例，第一行走机构102和第二行走机构302的结构可以相同也可以不同，具体类型不做特别限制，只要可以使得整机行走即可；并且第一行走机构102和第二行走机构302的行走驱动机构可以为行走马达。
在一个实施例中，第一行走机构102和第二行走机构302均为履带行走机构，主要包括车架和位于车架两侧的履带，并且车架的两侧分别设有行走马达，每个行走马达通过减速机与驱动轮连接，每侧的驱动轮均与该侧的履带连接，带动履带进行行走、转弯等动作。为便于描述，下文中将第一行走机构102的行走马达描述为第一行走马达103，将第二行走机构302的行走马达描述为第二行走马达303。通过作业机械1和运输机3均采用履带行走机构，可以使整体机械的接地压强更小，提高整体稳定性，从而适应复杂多变的地形，同时增大运输平台301的运输载荷，具有使用方便、场地适应性强等特点。
根据本申请的实施例，作业运输机还包括行走液压控制系统，用于控制第一行走机构102和第二行走机构302的行走、转弯等动作。
在一个实施例中，所述行走液压控制系统包括分流块7，所述分流块7设置为将所述作业机械上的液压泵提供的液压油分别分流至所述第一行走机构 102的行走驱动机构和第二行走机构302的行走驱动机构。也就是说，作业机械1上的第一行走机构102的行走驱动机构和第二行走机构302的行走驱动机构可以采用同一套液压控制系统进行控制，运输机的第二行走机构302不需要单独设置动力源。
其中，液压泵提供的液压油通过分流块7分流至第一行走机构102和第二行走机构302的具体油路设置可以有多种变形，在此不限制。
在一个实施例中，所述分流块7可包括两个，其中一个分流块7对应于作业运输机1一侧的第一行走机构102供油，另一个分流块7对应于作业运输机1另一侧的第一行走机构102供油。
如图4所示的实施例，行走液压控制系统主要包括分流块7，分流块7设置于作业机械1上，例如可以设置于第一行走机构102的车架底部，第一回转机构2的第一中央回转接头6分别与作业机械1的液压泵和分流块7的进口相连，液压泵提供的液压油经第一回转接头6流向分流块7，分流块7的第一出口经第二液压管路11与第一行走机构102的第一行走马达103相连，从而液压泵流出的液压油可以通过分流块7的第一出口流入第一行走马达103，以对作业机械1提供行走动力。
第二回转机构5上设置的第二回转接头9分别与分流块7的第二出口和第二行走机构302的行走驱动机构相连，第二出口的液压油经第二中央回转接头9流向第二行走机构302。具体如图4中的显示，第二回转机构5的第二中央回转接头9经第三液压管路12与分流块7的第二出口相连，第二中央回转接头9经第四液压管路13与第二行走机构302的第二行走马达303相连，这样液压泵流出的液压油通过分流块7的第二出口流入第二行走马达303，以对运输机3提供行走动力。
应当理解的是，本申请的实施例中的后车运输机3的动力源来自于前车作业机械1的液压泵，即整个机械共用一套行走液压控制系统，运输机3的行走由作业机械1提供动力并控制，不需要设置单独的动力源，即可实现对作业运输机前后两部分的四驱式行走进行控制。
此外，第一回转机构2的回转马达可以通过第一中央回转接头6连接的管 路通入液压油来控制上车体和下车体之间的回转。当然，也可以设置其它的油路向第一回转机构2提供液压油。同理，第二回转机构5的回转马达也可通过第二中央回转接头9连接的管路通入液压油，或者通过其它油路通入液压油。在另外的实施方式中，也可以在第二回转机构5中不设置驱动机构，即第二回转机构5为不通过驱动进行回转的自由回转机构。
根据本申请的实施例，如图4所示，行走液压控制系统还包括控制阀8，控制阀8设置于分流块7的第二出口，以控制分流块7第二出口的开闭，且第二中央回转接头9经可拆卸的液压管路与控制阀8相连。为便于更好地描述液压管路，该实施例中将第二中央回转接头9与控制阀8相连的可拆卸的液压管路描述为第三液压管路12。
本申请通过控制阀8可以控制第三液压管路12的通断。具体的，当作业运输机的作业机械1与运输机3通过下述连接体4进行可拆卸地连接合体时，控制阀8打开分流块7的第二出口，液压油分别送至作业机械1的第一行走马达103和运输机3的第二行走马达303，为作业机械1和运输机3提供行走动力；当作业机械1与运输机3通过下述连接体4分开时，控制阀8关闭分流块7的第二出口，以断开第三液压管路12，液压油全部送入作业机械1的第一行走马达103，以供作业机械1行走，以此获得更高的作业效率。
在一个实施例中，分流块7及控制阀8分别设有两个，作业机械1的液压泵将液压油送入第一中央回转接头6，然后通过第一液压管路10分别流至两个左右分流块7，通过分流块7实现前后液压管路分流，左右分流块7的一分部液压油通过第二液压管路11送至作业机械1的左右第一行走马达103，以控制作业机械1的行走动力；左右分流块7的另一部分液压油可以经控制阀8、第三液压管路12送至第二中央回转接头9，再由第二中央回转接头9通过第四液压管路13分别流入运输机3的左右第二行走马达303，以控制运输机3的行走动力。
在一个实施例中，由于作业机械1上车体101驾驶室内的电气控制系统与手柄相连，因此，可以将控制阀8与电气控制系统相连，这样，通过手柄即可控制控制阀8的通断，便于操作人员统一操控。
控制阀8的具体类型不做特别限制，只要可以控制分流块7的第二出口的开闭即可，例如可以为电控阀、液控阀、换向阀等。
并且，本申请第三液压管路12为可拆卸结构，当作业机械1与运输机3通过下述可拆卸的连接体4进行分开时，相应的，将第三液压管路12拆分，实现机械结构与液压管路的可拆卸匹配性。
根据本申请的实施例，可拆卸的第三液压管路12设有快速接头14。具体的，第三液压管路12包括快速接头、与控制阀8连接的第一管段以及与第二中央回转接头9连接的第二管段，第一管段和第二管段通过快速接头可拆卸连接。在本示例中，第三液压管路12对应下述连接体4的位置设有快速接头14。本申请通过设置快速接头14，方便第三液压管路12的前后两部分(即第一管段和第二管段)可以在连接体4处快速拆分，使作业运输机可以完全一分为二，前车作业机械1可以自由行走而不受影响，待作业机械1使用完毕再将作业机械1和运输机3在连接体4处通过快速接头14连接，从而重新组装成一个整体，也不会影响后车运输机3的液压动力。
根据本申请的实施例，可拆卸的第三液压管路12设有挠性连接段15。在本示例中，第三液压管路12对应连接体4的部分为挠性连接段15，即第三液压管路12在该处留有多余悬吊的液压胶管段，用于缓解作业运输机转弯时对此处液压管路的收缩与拉紧状态，避免对液压管路造成损坏以及对转弯造成干涉。
根据本申请的实施例，如图1所示，运输机3的运输平台301通过连接体4可拆卸地连接于作业机械1的下车体，具体连接于第一行走机构102的车架后端。通过将连接体4设置为可拆卸结构，实现作业机械1与运输机3的运输平台301的可拆卸连接，使作业机械1和运输机3两部分可以灵活拆分或组合，保留了作业机械1的灵活性，拆分下来的作业机械1可以随意行走完成各种作业任务，合体时可以实现运输功能，因此本申请可以根据具体工况选择分开作业或合体作业，灵活性高，场地适应性强。
根据本申请的实施例，如图5-图7所示，连接体4包括万向联轴器401和铰接件，万向联轴器401的第一端通过安装支架402与第一行走机构102的车架后端相连，万向联轴器401的第二端通过铰接件与运输平台301的前端相连。 通过万向联轴器401可以实现竖直方向和水平方向在一定角度范围内转动，通过铰接件可以实现在水平方向任意转动。该实施例中连接体4为可拆卸结构，可以实现作业机械1和运输机3的快速拆卸。具体可以将万向联轴器401的第一端与第一行走机构102的车架拆卸，也可以将铰接件与运输平台301的前端拆卸。
在一个实施例中，安装支架402为高强度钢板组成，包括主支架4021和分支架4022，主支架4021的前端与第一行走机构102的车架后端焊接，且主支架4021的后端向后延伸一端距离，具体延伸距离可根据实际工况进行调节，以使作业机械1的上车体101回转时不会碰到运输平台301为宜，这样，作业机械1的上车体可以实现360°的自由回转以进行灵活作业；分支架4022分别焊接于主支架4021的两侧且与第一行走机构102的车架后端焊接，用于提高安装支架402的稳定性和强度。
在本示例中，万向联轴器401为十字轴式万向联轴器，当然，也可以采用其他类型的万向联轴器。
根据本申请的实施例，铰接件为销轴403、挂钩或铰链等，可根据实际工况进行选择。
在一个实施例中，万向联轴器401的第二端设有第一连接耳板405，运输平台301的端部设有第二连接耳板407，第二连接耳板407位于第一连接耳板405的上方，所述铰接件包括可转动地穿在第二连接耳板405和第一连接耳板上407的销轴403，销轴403的伸出第一连接耳板405的一端或伸出第二连接耳板407的一端套设有限位轴管409，通过限位轴管409可以限制第一连接耳板405或第二连接耳板407脱离销轴403。
具体的，如图7所示，万向联轴器401的第二端焊接有竖向设置的第一安装板404，第一安装板404上焊接有横向布置的第一连接耳板405，运输平台301的前端底部焊接有竖向设置的第二安装板406，第二安装板406上焊接有横向布置的第二连接耳板407，且第二连接耳板407位于第一连接耳板405的上方，销轴403经第二连接耳板407竖向贯穿至第一连接耳板405的下方，实现第一连接耳板405与第二连接耳板407的铰接；且销轴403上套设有轴套408， 轴套408位于第一连接耳板405和第二连接耳板407之间，通过轴套408可以保护销轴403且支撑第二连接耳板407，使第一连接耳板405与第二连接耳板407具有高度差，便于装卸。第一连接耳板405与第二连接耳板407具体的高度差可根据实际工况进行调节，以使作业机械1的上车体101回转时不会碰到运输平台301为宜。
并且，销轴403的底端设有限位轴管409，限位轴管409位于第一连接耳板405的下方，通过螺栓410横向贯穿限位轴管409和销轴403，用螺母实现紧固，进而防止销轴403在竖直方向移动。在拆卸螺栓410，从而限位轴管409脱离销轴403的情况下，可以将销轴403抽出第一连接耳板405和第二连接耳板407，从而使得运输平台301与作业机械1的下车体分离。当然，在万向联轴器401的第一端与安装支架402可拆卸连接的情况下，也可以拆卸万向联轴器401与安装支架402的连接。
此外，第二安装板406的内侧与运输平台301的前端底部之间焊接有加强板411，以提高两者的连接可靠性。
根据本申请的实施例，运输平台301上设有隔板16，隔板16将运输平台301划分成多个挡料区域。如图8-图10所示，运输平台301上设有横纵交错布置的隔板16，以形成大小相等或不等的多个挡料区域17，以将物料存储在挡料区域17内，防止物料散落，可以理解的是，挡料区域17不局限于图中所示的方形，也可以为圆形、三角形、椭圆形等其他形状。
在一个实施方式中，运输平台301包括底板主体及在底板主体的两侧分别可转动连接的展板18，展板18通过转动而展开或收起。如图8-9所示，运输平台301的两侧分别通过铰链等装置可转动连接有展板18，展板18可展开或收起，展板18展开(水平布置)时可以增大运输面积，同时方便操作人员站立；展板18收起(竖直布置)时可以进一步阻挡物料，防止物料散落。
根据本申请的实施例，其中一个挡料区域17内设有前后设置的第一布管通孔19和第二布管通孔20，该挡料区域17位于运输平台301的中部，该实施例通过设置第一布管通孔19和第二布管通孔20，便于第二中央回转接头9的液压管路的安装。具体的，第二中央回转接头9设置于第二布管通孔20处，且该 挡料区域17设有盖板21，便于对该挡料区域进行密封，防止作业物对该挡料区域内的布管通孔和第二中央回转接头9造成干涉破坏。
在一个实施例中，行走液压控制系统的所有液压管路均从作业运输机的底部进行布置，第三液压管路12从底部向上伸入第一布管通孔19至挡料区域17内，然后再伸向第二布管通孔20与第二中央回转接头9相连，通过该设置，便于第三液压管路12与第二中央回转接头9的布管连接。
根据本申请的实施例，作业机械1的上车体101与挖掘机的上车体大致相同，主要包括：设置于转台上的驾驶室、工作装置等部件，工作装置包括可动作的作业臂、与作业臂相连的执行属具。其中，如图11所示，本申请工作装置的执行属具不仅可以使用挖掘用铲斗22，同时也可以替换成贝壳斗23、液压剪24、破碎锤25、抓木器26和打桩锤27等执行属具，用于实现除挖掘以外其他抓取、剪切、破碎等作业，完成多种执行属具所具有的不同作业功能，达成多功能集成作业运输机的目的，提升作业运输机的利用率和适应性。因此，本申请作业运输机的工作装置具有可替换性，使作业运输机的应用范围大大增加，可以在复杂的工况下，通过替换执行属具，完成普通挖掘机不能完成的任务，提高了产品的功能性和实用性。
可以理解的是，本申请作业机械1的其他结构与挖掘机类似，此处不作详述。
基于上述实施例，下面对本申请提供的作业运输机的工作原理进行描述，主要包括：当作业机械1和运输机3通过连接体4合体时，遇到转向和行走路面不够平整的工况，利用万向联轴器401和销轴403连接的后车运输机3可以直接进行水平方向和竖直方向的转动，转动角度由万向联轴器401的转动角度范围决定；并且，由于后车运输机3具有第二回转机构5，在水平方向转动较大角度时，在连接体4和适当控制后车运输机3行走方向的配合下，整机可以顺利完成转弯动作；另外，当前车作业机械1原地转动时，在销轴403的配合下，前车作业机械1也可以顺利完成原地转动。
当作业机械1需要独立作业时，可以选择对销轴403进行快速拆卸；且在液压管路方面，可以通过快速接头14对第三液压管路12进行拆分，这样可以 避免常规油路连接方式拆卸时发生的漏油情况，同时通过调整控制阀8的液压流向，对控制阀8与快速接头14处的第三液压管路12进行断开卸荷，此时液压泵流量全部供给作业机械1行走，以此获得更高的作业效率。此外，拆卸后的作业机械1可以避免后车运输机3带来的限制，进行大范围自由作业；当作业机械1作业完毕，运输平台301装载完成，可以通过连接体4、快速接头14与运输平台301重新连接，实现作业及运输的一体化操作。
最后应说明的是：以上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精神和范围。
