本实施例提供一种排泄物筛分装置，对含有排泄物的猫砂进行筛分，为宠物猫提供良好干净的排便场所。如图1-图4所示，该排泄物筛分装置包括转动容置件1、挡砂件2和筛分件3。转动容置件1内铺设有猫砂100(图1-图4中未示出)，宠物猫进入转动容置件1内在猫砂100上排泄完之后，挡砂件2被配置为对转动容置件1内的猫砂100进行阻挡，筛分件3被配置为对猫砂100中的排泄物200进行筛分。在本实施例中，转动容置件1可以为桶状，可以通过前后两个半桶拼接而成，挡砂件2可以为板状，筛分件3可以为弧形板状。
在一实施例中，转动容置件1被配置为容置猫砂100，转动容置件1的侧壁上设置有排废口11。排废口11的长度方向可以与转动容置件1的轴线方向平行。挡砂件2设置于转动容置件1内，挡砂件2被配置为在转动容置件1沿第一方向转动时挡住猫砂100。挡砂件2可以与转动容置件1一体成型，以排废口11的侧壁为延伸根部。筛分件3设置于转动容置件1内，筛分件3上设置有多个筛分孔31，筛分件3、挡砂件2以及转动容置件1的内侧壁围设形成容纳腔14。筛分件3与挡砂件2均位于排废口11的同一侧，便于形成容纳腔14。筛分孔 31可以为正六边形，美观大方，筛分效率高。
在使用时，将猫砂100放置于转动容置件1内，当宠物猫将排泄物200排至猫砂100内并从转动容置件1出去后，将转动容置件1沿第一方向转动，含有排泄物200的猫砂100经由筛分件3的筛分孔31过滤筛分，猫砂100进入容纳腔14内，并被挡砂件2挡住，随着转动容置件1的转动，在重力作用下，筛分件3表面被筛分出的排泄物200经由排废口11排出，转动容置件1沿与第一方向相反的方向转动至初始位置，容纳腔14内的干净猫砂100回到预设位置。
为保证转动容置件1的转动平稳性，可选地，该排泄物筛分装置还包括支撑座4，支撑座4上设置有多个被配置为承载转动容置件1的辅助支撑轮41。在本实施例中，支撑座4上设置有四个辅助支撑轮41，四个辅助支撑轮41分布于支撑座4的四个角，以受力均匀地对转动容置件1进行支撑并辅助转动容置件1转动。在其他实施例中，也可以设置六个、八个等多个辅助支撑轮41，视应用情况和转动容置件1所需的承载载荷而定。为便于收集由排废口11排出的排泄物200或旧猫砂100，可选地，支撑座4内设置有排废通道(图中未示出)，排废通道的下方设置有收纳盒(图中未示出)。
为便于对转动容置件1进行驱动，可选地，转动容置件1连接有驱动组件，驱动组件被配置为驱动转动容置件1绕自身轴线转动。在本实施例中，转动容置件1上设置有一体成型的从动齿轮13，转动容置件1通过轴和轴承连接结构转动设置于中心轴座5上，实现绕其轴线的转动，驱动组件采用常见的驱动电机和主动齿轮，主动齿轮位于从动齿轮13下方，并与从动齿轮13啮合，驱动电机的输出端将动力传递至主动齿轮，主动齿轮将动力传递至从动齿轮13，进而带动转动容置件1绕其轴线转动，为转动容置件1的转动提供驱动力。为便于检测是否有宠物猫进出转动容置件1的进出口15，可选地，转动容置件1的进出口15处设置有检测模块(图中未示出)，检测模块被配置为检测宠物猫是否穿过转动容置件1的进出口15，在筛分过程中，如果检测模块检测到宠物猫进入转动容置件1，需通过驱动组件紧急停止筛分过程。检测模块可选用市面上通用的红外线接收模块，例如深圳市肯森斯科技有限公司生产的kingsensor C20-4810红外线检测光栅传感器。
如图5和图6所示，为便于后续对筛分件3进行清理维修，可选地，筛分件3可拆卸地枢接于转动容置件1内。由于排泄物200和猫砂100会部分粘在筛分件3上，甚至堵塞筛分孔31，导致筛分件3使用一段时间后筛分效果变差，而需要定期进行更换和清洗，本实施例中，筛分件3采用可拆卸的枢接结构安装在转动容置件1内，提高了对筛分件3进行更换和清洗的效率，延长了产品使用寿命。为方便拆装，可选地，转动容置件1的内侧壁上设置有第一安装轴 12(如图3和图4所示)和第二安装轴(图中未示出)，筛分件3的一端设置有与第一安装轴12配合的第一安装套32(如图5和图6所示)，另一端设置有与第二安装轴配合的第二安装套33(如图5所示)。如图6所示，为增大筛分接触面积，可选地，筛分件3背向容纳腔14形成弧形凸起，在不减少容纳腔14体积的情况下，提高了筛分效率。
本实施例提供的排泄物筛分装置，工作原理如下：
如图7所示，转动容置件1处于初始位置，含有猫排泄物200的猫砂100铺设于转动容置件1的底部，通过驱动组件将转动容置件1由初始位置沿第一方向(逆时针方向)转动。
如图8和图9所示，在转动容置件1沿第一方向转动过程中，筛分件3逐渐与含有猫排泄物200的猫砂100接触，并对排泄物200进行筛分，排泄物200(粘连有少量猫砂100)较大不能通过筛分件3的筛分孔31，猫砂100较小可以通过筛分件3的筛分孔31进去容纳腔14内，并由挡砂件2挡住，防止猫砂100从排废口11流出，排泄物200在重力作用下，经由排废口11排出。
如图10和图11所示，将转动容置件1沿与第一方向相反的方向(顺时针方向)转动，猫砂100将筛分件3推开，筛分件3绕其枢接处逆时针转动一定角度，方便快速地将猫砂100恢复至预设位置。
本申请提供的排泄物筛分装置，将猫砂放置于转动容置件内，当宠物猫将排泄物排至猫砂内并从转动容置件出去后，将转动容置件沿第一方向转动，含有排泄物的猫砂经由筛分件的筛分孔过滤筛分，猫砂进入容纳腔内，并被挡砂件挡住，随着转动容置件的转动，在重力作用下，筛分件表面被筛分出的排泄物经由排废口排出，转动容置件沿与第一方向相反的方向转动至初始位置，容纳腔内的干净猫砂回到预设位置。
本实施例提供的排泄物筛分装置结构简单，操作方便，自动化程度高，环保卫生，为宠物猫提供了良好干净的排便场所，实现了宠物猫排泄物200的自动化清理，无需经常性地替换猫砂100，避免了猫砂100使用上的浪费，无需人为铲砂排砂，为饲主带来愉快的饲养体验。
本实施例还提供一种排泄物筛分方法，使用上述的排泄物筛分装置，该排泄物筛分方法包括如下步骤：
S10、转动容置件1由初始位置沿第一方向转动。
S20、含有排泄物200的猫砂100经由筛分件3过滤筛分。
S30、猫砂100进入容纳腔14内，并被挡砂件2挡住。
S40、排泄物200经由排废口11排出。
S50、转动容置件1沿与第一方向相反的方向转动至初始位置。
S60、容纳腔14内的猫砂100回到预设位置。
为保护宠物猫，可选地，在步骤S10之前，进行如下步骤：检测宠物猫是否两次穿过转动容置件1的进出口15。
在多次使用猫砂100后，为将旧猫砂100排出转动容置件1外，可选地，在步骤S60之后，进行如下步骤：转动容置件1由初始位置沿与第一方向相反的方向继续转动；猫砂100经由排废口11排出。
本实施例提供的排泄物筛分方法，操作方便，自动化程度高，环保卫生，为宠物猫提供了良好干净的排便场所，实现了宠物猫排泄物200的自动化清理，无需人为铲砂排砂，为饲主带来愉快的饲养体验。
