Description

一种液压油箱组件及作业机械
本申请要求于2020年11月18日提交到中国国家知识产权局的申请号为202022679391.8、发明名称为“一种液压油箱组件及作业机械”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及液压油箱技术领域，具体而言，涉及一种液压油箱组件及作业机械。
背景技术
目前，大部分工程机械通过液压系统进行作业，液压系统主要包含液压泵、液压阀、液压缸、液压马达、液压油等，其中液压油储存在液压油箱中，作为工作介质具有能量传递、润滑等作用。通过液压油泵从液压油箱中吸出液压油，对液压油加压后通过液压管路、液压阀等部件输送到液压油缸等执行元件，做功后的液压油经回油管路回到液压油箱周而复始地工作循环。由于工作环境如温差变化大，产生冷凝水，或者混凝土泵车泵送油缸处带入水分等工作环境的影响，加上液压油流通路径上存在杂质污染物等跟随进入油箱，因此液压油箱除了具有储存液压油功能之外，还需兼具分离液压油中的水分、气泡和杂质的作用。
水和杂质在自身重力作用下会沉积到液压油箱的底部，需要及时处理，以防止再次进入液压系统产生污染。例如回油管路中的液压油回到液压油箱时的冲力使得沉积在液压油箱底部的杂质再次被搅起，混入液压油中将液压油污染。杂质随液压油的循环侵入液压系统可能造成液压阀件的液压阀芯的磨损甚至卡死，或者液压油缸内部的密封件和活塞杆的磨损，导致液压油缸的泄漏，影响具有液压系统的工程机械的正常使用，甚至产生事故。另外，含水量过多则会导致液压油乳化，造成润滑性能降低而加速高应力部件的磨损、产生气蚀损害、产生酸性物质腐蚀金属等等危害，影响工作可靠性。因此需要及时清理油箱底部的水和杂质，以提高可靠性。
为此，现有技术采用在液压油箱的底部直接设置油水分离存储器，油水分离存储器的底部设置排水管，以在重力作用下，使得液压油箱中的水流入油水分离存储器内，减少搅动涡流引起的水与液压油的再次混合造成的液压油污染，并通过排水管将水及时排出。但这种方式由于液压油箱和油水分离存储器仍为一个连通的整体，因此油和水实质上仍同时存在于同一容器中，在受到搅动涡流时依旧会再次混合造成液压油的污染。
发明内容
本申请旨在至少解决现有技术或相关技术中存在的技术问题之一。
为此，本申请的一个目的在于克服现有技术中的液压油箱仍不能避免油水再次混合造成液压油的污染的缺陷，从而提供一种可以最大程度上避免油水再次混合，以降低液压油的污染的液压油箱组件。
本申请的另一个目的在于提供一种作业机械。
为了实现上述目的，本申请第一方面的技术方案提供了一种液压油箱组件，包括：油箱本体，用于储存液压油，具有第一开口，所述第一开口设于所述油箱本体的底壁上；存储筒，设于所述油箱本体的下方，具有第二开口，所述第二开口通过输送管路与所述第一开口连通。
可选地，所述输送管路上设有第一阀门。
可选地，所述存储筒上设有第三开口，所述油箱本体上设有第四开口，所述第三开口和第四开口通过回流管路连通设置。
可选地，所述第三开口设于所述存储筒的顶壁上，所述第四开口设于所述油箱本体的侧壁的远离底壁的预定位置处。
可选地，所述回流管路上设有第二阀门。
可选地，所述存储筒的底壁上设有排放管路，所述排放管路上设有第三阀门。
可选地，所述存储筒为塑料材质、铝合金材质或内壁经防锈处理的铁质中的任一种。
可选地，所述存储筒的侧壁上设有液位指示结构。
可选地，所述液位指示结构为水位指示计或水位传感器。
可选地，还包括与所述液位指示结构连接的报警器。
可选地，还包括与所述第三阀门、液位指示结构和报警器均信号连接的控制器。
本申请第二方面的技术方案提供了一种作业机械，包括本申请所述的液压油箱组件。
根据本申请的技术方案，具有如下优点：
1.本申请提供的液压油箱组件，存储筒设于油箱本体的下方，且第二开口通过输送管路与第一开口连通。当油箱本体中储存的液压油中混入水和杂质时，由于水和杂质的密度大于液压油的密度，因此水和杂质会在自身重力作用下经油箱本体的第一开口、输送管路和存储筒的第二开口进入存储筒中自动收集，从而实现水和杂质与液压油在物理空间上的隔离，通过输送管路的设置尽量减小了二者的连通面积，降低了扰动再次污染油箱本体中的液压油的概率，同时消除了水和杂质沉积在油箱本体底部可能腐蚀油箱本体的隐患；另外，将油箱本体和存储筒分开设计，减小了油箱本体的体积，节省了空间。
2.本申请提供的液压油箱组件，存储筒的顶壁上设有第三开口，油箱本体的侧壁的远离底壁的预定位置处设有第四开口，第三开口和第四开口通过回流管路连通设置。这样，随水和杂质一同进入存储筒中的少量液压油由于密度较小，漂浮在存储筒的上方，在油箱本体中的液压油的压力作用下可经存储筒的第三开口和油箱本体的第四开口再次回收至油箱本体中，节约了资源。
3.本申请提供的液压油箱组件，存储筒侧壁上液位指示结构和报警器的设置，可以实时监测存储筒中的液位情况，并发出报警，提醒及时排水。
本申请的附加方面和优点将在下面的描述部分中变得明显，或通过本申请的实践了解到。
附图说明
本申请的上述和/或附加的方面和优点从结合下面附图对实施例的描述中将变得明显和容易理解，其中：
图1为本申请提供的液压油箱组件的示意图。
其中，图1中附图标记与部件名称之间的对应关系为：
1、油箱本体；2、存储筒；3、第四开口；4、第一开口；5、第二开口；6、第三开口；7、输送管路；8、回流管路；9、第一阀门；10、第二阀门；11、排放管路；12、第三阀门；13、液位指示结构。
具体实施方式
为了能够更清楚地理解本申请的上述目的、特征和优点，下面结合附图和具体实施方式对本申请进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本申请，但是，本申请还可以采用其他不同于在此描述的其他方式来实施，因此，本申请的保护范围并不受下面公开的具体实施例的限制。
如图1所示的液压油箱组件的一种具体实施方式，包括用于储存液压油的油箱本体1和与油箱本体1连通的存储筒2。
油箱本体1具有第一开口4，在所述油箱本体1的侧壁的远离底壁的预定位置处设有第四开口3，该预定位置为油箱本体1中的水和杂质达到最大沉积量时，高于该最大沉积量的水和杂质的上表面的位置，以防止回收的液压油与水和杂质再次混合。优选的，在所述油箱本体1的底壁上设有所述第一开口4，第一开口4靠近油箱本体1的边缘设置。
存储筒2设于所述油箱本体1的下方，为塑料材质，容积较大，可以延长排放周期，减少排放操作强度。存储筒2具有第二开口5和第三开口6，所述第二开口5通过输送管路7与所述第一开口4连通，且低于所述第一开口4设置，所述第二开口5和第三开口6均设于所述存储筒2的顶壁上，且分设在存储筒2顶壁的两侧。
在所述第三开口6和第四开口3之间设置有回流管路8。当存储筒2的液压油积累到一定程度时，可以通过将油箱本体1中的液压油排放一部分至存储筒2中，通过液压油提供的压力，将存储筒2上部漂浮的液压油依次经由第三开口6、回流管路8和第四开口3而重新回收至油箱本体1中再次利用，以节约资源。
为实现自动精准控制，在所述输送管路7上设有第一阀门9，所述回流管 路8上设有第二阀门10，所述存储筒2的底壁上设有排放管路11，所述排放管路11上设有第三阀门12。所述存储筒2的侧壁上设有作为液位指示结构13的水位传感器，所述水位传感器连接有报警器。所述第三阀门12、液位指示结构13和报警器均与控制器信号连接。
在油箱本体1正常工作时，第一阀门9和第二阀门10处于打开状态，第三阀门12处于关闭状态，油箱本体1中的水和杂质在重力作用下向油箱本体1底部沉积，并依次经由油箱本体1的第一开口4、输送管路7、存储筒2的第二开口5进入存储筒2中收集。同时，少量液压油随水和杂质一同进入存储筒2中，且漂浮在上部，此时由于存储筒2和油箱本体1通过回流管路8连通，这样当漂浮在上部的液压油受到油箱本体1中排出的液压油的压力时，会依次经第三开口6、回流管路8和第四开口3再次回收至油箱本体1中。当水位传感器监测到存储筒2中的积水量达到一定程度时，报警器发出报警，控制器控制第三阀门12打开，进行排水。
本申请还提供了一种作业机械，包括所述的液压油箱组件。
作为替代的实施方式，在油箱本体1和存储筒2之间可以不设置回流管路8，当存储筒2上方漂浮的液压油达到一定量时，可以通过输送管路7重新回收至油箱本体1中。
作为替代的实施方式，第三开口6还可以设于存储筒2的侧壁的靠上位置，即高于水面的位置，第四开口3设于油箱本体1底壁上，以防止将存储筒2中的水再次鼓入油箱本体1中。
作为替代的实施方式，也可以不设置第一阀门9、第二阀门10和第三阀门12，当水位传感器监测到存储筒2中的水量达到一定值，报警器发出报警时，首先切断存储筒2与油箱本体1的连接，并封住断口，然后打开存储筒2底部设置的封堵盖，即可排水。
作为替代的实施方式，也可以不设置控制器，通过手动开闭第三阀门12。
作为替代的实施方式，可以在回流管路8上设置泵体，泵体工作将存储筒2上部漂浮的少量液压油回收至油箱本体1中。
作为替代的实施方式，所述存储筒2为铝合金材质或内壁经防锈处理的铁质。
作为替代的实施方式，所述液位指示结构13为水位指示计。
