 本发明的实施方式
下面结合附图详细说明本实用新型的技术方案：
实施例一
如图1和2，一种半圈式捞渣装置，包括本体1和两部分别通过一驱动轴7与本体1进行转动连接的渣耙3，所述渣耙3位于本体1的下方。
所述本体1中设有驱动体4和两支与驱动轴7一一对应的曲柄2。
所述驱动体4通过滑动配合方式安装在本体1上（比如安装在本体1内的滑槽中）。所述捞渣装置还包括用于驱动所述驱动体4相对于本体1前后移动的捞渣驱动装置。
所述驱动体4上设有左右走向的横槽5。各曲柄2的一端与对应的驱动轴7固定连接、另一端与所述横槽5相配合，以实现沿横槽5的左右移动和相对转动。
当所述驱动体4移动时，曲柄2的另一端在横槽5中移动，并带动渣耙3进行转动。
所述驱动体4可以是一个T形板结构，也可以是一个整体的移动板，还可以是其它的形状。
一般的，所述捞渣驱动装置为驱动缸10，所述驱动缸10与所述驱动体4直接连接，或通过捞渣传动组件与所述驱动体4相连接。
如图2和3，捞渣传动组件可以是一个简单连接件，但优选是基于杠杆机构原理的结构，以增大渣耙3的驱动力：所述捞渣驱传动组件包括摆动杆8和转动块9。所述摆动杆8可相对于本体1转动（比如与本体1铰接，或者与其它相对于本体1固定设置的部件铰接），所述驱动缸10一端与摆动杆8铰接、另一端可相对于本体1转动（与摆动杆8类似）。
所述转动块9通过转动连接方式安装在驱动体4后端的圆孔中，且该转动连接的轴线为左右走向。所述摆动杆8的下端穿过所述转动块9上的连接孔，可以相对于转动块9上下滑动。
当驱动缸10伸缩时，带动摆动杆8摆动，摆动杆8的下端通过转动块9驱动驱动体4前后移动。
进一步的，捞渣装置还包括用于驱动本体1前后移动的水平移动机构，方便进行水平移动，完成捞渣或其它操作。
如图4，具体的，所述水平移动机构包括水平架11以及移动座13。所述移动座13上安装有沿水平架11滚动的移动轮14，移动轮14分布在水平架11的上下两侧，减小二者相对移动时的阻力。所述水平移动机构还包括驱动所述移动座13沿水平架11移动的水平驱动机构。优选的，所述水平驱动机构为伸缩缸12，所述伸缩缸12一端与水平架11相连接、另一端与所述移动座13相连接。
所述本体1可以安装在移动座13的下端或旁侧，在伸缩缸12的作用下进行水平移动。
进一步的，所述移动座13下端还可以安装一个回转驱动装置，用于驱动本体1相对于移动座13绕竖直轴线做360度回转运动，方便清理金属液容器16内壁粘挂的渣子。
如图1和2，捞渣装置还包括固定板6，所述固定板6位于两个渣耙3之间并相对于本体1固定设置。优选的，所述驱动轴7上分别安装有一转动套，驱动轴7可相对转动套自由转动。固定板6的两端则分别与转动套相连接。固定板6可以消除两个渣耙3之间的盲区。
进一步的，如图1和5，所述渣耙3包括立板3-1和底板3-2，还包括位于立板3-1底端外侧的、可拆卸的刮渣板3-3。底板3-2一般是倾斜设置的，靠近立板3-1底部的一侧较高，靠近两个渣耙3中心位置的一侧较低。刮渣板3-3的作用是将渣耙3底板3-2下面的渣子刮出，留待下一次捞渣时捞出。
优选的，所述立板3-1和固定板6都是圆弧形的，方便在捞渣初始状态下与圆形的金属液容器16内壁贴合。
进一步的，所述底板3-2和刮渣板3-3为一体，通过可拆卸方式（如螺栓连接）与所述立板3-1相连接，方便整体更换。
如图6至9，捞渣过程如下：初始时，渣耙3底部压入渣层一定深度或者与金属液面接触，两个渣耙3展开，渣耙3立板3-1的外侧以及固定板6的外侧与金属液容器16一端的内壁贴近，注意此时固定板6和渣耙3的立板3-1所组成的外圆弧面是与容器内壁的形状相吻合的。然后，通过载具（挖掘机或其它机械臂）或者载具末端安装的水平移动机构带动本体1开始向金属液容器16的另一端移动，移动过程中，通过控制驱动体4的移动，使渣耙3进一步展开，使渣耙3的末端始终贴近金属液容器16的内壁。在渣耙3的末端经过金属液容器16的最宽处之后，驱动体4开始控制渣耙3合拢，同时要保证渣耙3的末端仍紧贴金属液容器16的内壁行走，直至两个渣耙3合拢，此时渣子已经聚拢并抱入两渣耙3合拢形成的空间内。然后控制渣耙3上升，移动到目标位置后，渣耙3张开，将渣子释放，并准备开始下一次捞渣。
捞渣过程中，两个渣耙3的转动角度接近90度，整个捞渣机构只实现了180度（半圈）的展开与合拢，但通过渣耙3立板3-1形状的特殊设计以及渣扒运动的控制，可以实现容器内几乎百分之百面积的捞渣。
捞渣路线可以是前后直线，也可以是左右直线，还可以根据金属液容器16的形状和捞渣装置的位置进行设定。
实施例二
如图10和11，本实施例与实施例一的不同之处在于，所述驱动体4上不带有横槽5，而是通过两个连杆15分别与两侧的曲柄2进行连接。连杆15的一端与驱动体4转动连接、另一端与对应的曲柄2转动连接。在驱动体4前后移动时，可以带动渣扒张开或合拢。
本实施例的捞渣过程与实施例一相仿，依然是以张开状态从一端开始，在向另一端移动的过程中要保证渣耙3的末端紧贴金属液容器16的内壁，不做赘述。
其它实施方式
还可以通过其它的结构方式实现上述半圈式捞渣，例如：在驱动体上设置齿条，渣耙的驱动轴上设置与齿条啮合的齿轮。但这种方式的齿轮惯量较大，需要的驱动力较大，可以在齿轮上增加镂空结构，尽量减小其惯量。
