发明概述
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。
本发明实施例提供一种斗式提升机的清洁装置。
本发明实施例还提供一种斗式提升机。
本发明实施例还提供一种清洁斗式提升机的方法。
本发明实施例提供的斗式提升机的清洁装置包括：
支架、转动体、至少三个清洁管以及流体输送管路；所述转动体以可旋转的方式安装在所述支架上，
每个清洁管的一端均附接于所述转动体，
所述流体输送管路与所述至少三个清洁管流体连通，
所述清洁装置被设置为：在所述斗式提升机的料斗行进接近清洁装置时，所述至少三个清洁管中的一个的另一端位于一料斗的开口侧，且该清洁管与该料斗行进的方向成角度；随着该料斗的行进，该料斗的边缘接触位于该料斗的开口侧的该清洁管并对其施加外力，该清洁管及所述转动体被该外力推动而转动，直到该清洁管的另一端离开该料斗的开口侧为止，且随着所述转动体的转动，后续另一清洁管转动以致该另一清洁管的另一端相对于后续另一料斗，位于该另一料斗的开口侧。

洁。也可以使用其他合适的流体，例如水，来进行清洁。
本发明实施例的支架用于承载转动体。清洁管的一端附接在转动体上，清洁管的另一端伸向料斗行进的路径，并与料斗行进的方向成角度。清洁管与料斗行进方向的角度大于0°且小于90°。角度为90°时，清洁管与料斗行进方向垂直，无法进行清洁；角度为0°时，清洁管与料斗行进方向平行，也无法进行清洁。
在一些本发明实施例中，清洁管与料斗行进方向的角度可以是变化的，可以随着料斗的行进而逐渐改变角度。也就是说，随着清洁的进行，清洁管与料斗行进方向的角度可以在大于0°且小于90°的范围内变化。
本发明实施例提供的斗式提升机包括任何一种本发明实施例的清洁装置，所述支架安装在所述斗式提升机的内侧壁上，且所述至少三个清洁管中的一个的另一端位于所述斗式提升机的一料斗的开口侧。

图2是本发明实施例的斗式提升机清洁装置及相关部件的侧视示意图；

发明详述
以下对本发明实施例的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明实施例，并不用于限制本发明实施例。
本发明实施例的清洁装置利用流体对料斗进行清洁，且使用转动清洁的方式，不会影响斗式提升机的正常传动。
图2是本发明实施例的斗式提升机清洁装置及相关部件的侧视示意图，应用于具有箱体的斗式提升机(可参照图1)，图3是其中清洁装置的俯视图。
本发明实施例的清洁装置包括支架，转动体、至少三个清洁管以及流体输送管路；所述转动体以可旋转的方式安装在所述支架上，每个清洁管的一端均附接于所述转动体，所述流体输送管路与所述至少三个清洁管流体连通，所述清洁装置被设置为：在所述斗式提升机的料斗行进接近清洁装置时，所述至少三个清洁管中的一个的另一端位于一料斗的开口侧，且该清洁管与该料斗行进的方向成角度；随着该料斗的行进，该料斗的边缘接触位于该料斗的开口侧的该清洁管并对其施加外力，该清洁管及所述转动体被该外力推动而转动，直到该清洁管的另一端离开该料斗的开口侧为止，且随着所述转动体的转动，后续另一清洁管转动以致该另一清洁管的另一端相对于后续另一料斗，位于该另一料斗的开口侧。
如图2和图3所示的示例中，支架安装在料斗下降一侧的箱体的内侧壁
上。支架包括支臂13及与支臂13连接的一转轴14，转轴14在水平方向上延伸。虽然示例中的该支架整体为L型，但也可以做成U型，即该支架具有2个支臂，或其他任意的形状。转动体安装在该转轴14上，即转轴14垂直于转动体的旋转面延伸。所述至少三个清洁管沿着所述转动体的径向伸出且在所述转动体上均匀布置，图2-3中，转动体为开有中心孔的转盘11，转盘11通过该中心孔套设在转轴14上，可以是直接套设，也可以通过轴承套设在转轴14上。转盘11的径向上均匀布置有4个清洁管12，也可以是3个或5个或6个或更多个，清洁管12的底部与转盘11的空腔连通。图2-3中，流体输送管路包括转动体如转盘11上的一流体输送口15及与流体输送口15连接的一段软管16，还可以包括穿过所述箱体的一段管路17。通过流体输送管路将流体引入转盘11的空腔，再从各个清洁管12喷出。
除了清洁装置，图2中还示出了斗式提升机的机箱的一个内侧壁21，及斗式提升机构上的料斗20及与料斗20连接的传送链条22。侧壁21位于料斗20行进的一侧，支臂13安装在侧壁21上。在转盘11的任一旋转位置均有一个清洁管12伸入到料斗20的行进路径上，即清洁管12伸入到料斗20的开口的一侧。这样，当料斗20行进时，一清洁管12与一料斗20的边缘接触并随该料斗20继续行进而被推动向行进方向旋转。值得说明的是，在向行进方向旋转过程中，该清洁管12的清洁头所对准的料斗的位置会由近及远地变化，使得清洁管12可以自动对料斗的各个位置加以清洁，结构简单而效果良好。如料斗较大时，为了具有更好的清洁效果，可以在清洁管12的头部设置多个清洁头，这些清洁头可以朝向不同的方向，从而对料斗做全面的清洁。在料斗20之间的间隔较小时，转动体上的清洁管可以设置较多，而在料斗20之间的间隔较大时，转动体上的清洁管可以设置较少，使得该清洁管12与该料斗20脱离时，与该清洁管12相邻的后一清洁管12伸入到与该料斗20相邻的后一料斗20的行进路径上，如此循环，使得该清洁装置可以对各个料斗进行清洁而不需要任何额外的驱动装置。
本发明实施例中涉及的支架、清洁管、流体输送管路、转动体以及其他相关的部件可以是常规的或已有的。在此处所述的本发明实施例的斗式提升机及其清洁装置上可以进行变动，而不背离如权利要求中所限定的本发明实
施例的原理和范围。虽然可以许多不同形式来使本发明实施例具体化，但是此处详细描述本发明实施例的一些实施方案。本公开内容是本发明实施例的原理的示例，且并不规定为使本发明实施例限于所示的具体实施方案。此外，本发明实施例包括此处所述的各种实施方案的一些或全部的任意可能的组合。在本申请中或在任一个引用的专利、引用的专利申请或其它引用的资料中任何地方所提及的所有专利、专利申请和其它引用资料据此通过引用以其整体并入。
以上公开内容规定为说明性的而不是穷尽性的。对于本领域技术人员来说，本说明书将暗示许多变化和可选择方案。所有这些可选择方案和变化规定为被包括在本权利要求的范围内，其中术语“包括”意思是“包括，但不限于”。本领域技术人员应认识到此处所述的实施方案的其它等效变换，这些等效变换也规定为由本权利要求所包括。
在此完成了对本发明实施例可选择的实施方案的描述。本领域技术人员可认识到此处所述的实施方案的其它等效变换，这些等效变换规定为包括在由附于本文的权利要求范围内。
本发明实施例提供的清洁装置利用流体对料斗进行清洁，不会影响斗式提升机的正常传动。清洁装置结构简单，且清洁管对料斗的清洁位置会自动地移动，清洁的效果良好。
