需要注意的是，本实用新型实施例所描述的“上”、“下”、“左”、“右”等方位词是以附图所示的角度来进行描述的，不应理解为对本实用新型实施例的限定。此外在上下文中，还需要理解的是，当提到一个元件被形成在另一个元件“上”或“下”时，其不仅能够直接形成在另一个元件“上”或者“下”，也可以通过中间元件间接形成在另一元件“上”或者“下”。
本实用新型一个实施例提供了捡发球一体机，其具有可工作于捡球模式的发球部，从而利用一个机械结构同时完成发球和捡球两个功能，大大缩小了设备体积，提高了设备的便携性。本实用新型的捡发球一体机可以用于网球，也可以用于其他类似的球类，本实施例不做具体限定。
参见图1-图4，捡发球一体机包括上部机体1和下部机体8。
上部机体1包括球筐和捡球导向槽的上槽体2，捡球导向槽的上槽体2的出口位于球筐的顶部，球筐的底板5上固定有搅拌电机4，搅拌电机4驱动搅拌盘3转动，搅拌盘3中有四个直径大于球直径的出球孔25，搅拌盘3带着四个出球孔25上的球体19旋转，当其中一个球转到下球孔20时，球体19会由于重力作用落入发球导球部18中。
可选的，出球孔25的数量可以多于四个，也可以少于四个，本实施例不做具体限定。
更优选的，搅拌电机4除了可以固定在底板5上，还可以固定在球筐
侧壁或者其他适当位置处，此时搅拌电机5的输出轴可以通过齿轮、传送带等传动机构间接驱动搅拌盘3。
更优选的，为了防止搅拌盘不工作时，球体落入下球孔中，在所述搅拌盘的上方且对应所述下球孔的位置处设置止挡部，该止挡部可以为挡片、挡块、挡条等各种造型，能起到止挡作用即可。
进一步的，发球导球部18可以为长条形状的槽、漏斗形状的槽、硬质或软质管道、或含有中间过渡的槽的组合。只要能够将球体导入到发球轮处即可，本实施例并不限定该发球导球部18的具体结构。
进一步的，球筐的材质可以为塑料、金属、布料或类似材料的一种或多种组合。球筐可以做成向内或向外可折叠，或者升降式，或者可拆卸式，以减少携带运输体积。例如在携带运输时，球筐四个立面，可以分别向下嵌入到下部机体8中，或者球筐的四个立面向外折叠180度与下部机体8贴合。
进一步的，捡球导向槽上槽体2的材料可以为塑料、金属、布料或类似材料的一种或多种组合，其可以做成可拆卸的、可升降的结构，以减少携带运输体积。例如，在携带运输时，捡球导向槽上槽体2可以向下降落到下部机体8中，或者可拆卸后插入到下部机体8中空余空间，则可以大大缩小携带运输的体积。
下部机体8包括发球部和捡球导向槽的下槽体17。发球部包括发球轮、发球轮支架、发球轮驱动机构、发球轮支架驱动机构等，发球轮通过摩擦挤压的方式将球体发射出去，发球轮的数量可以是两个、三个或四个，本实施例不做具体限定。
下面以两个发球轮的发球部为例进行具体说明。
发球部包括上发球轮9、下发球轮13、第一球轮支架11、发球轮驱动机构、发球轮支架驱动机构和发球导球部18，捡球导向槽的下槽体17的入口贴近地面16。其中，发球轮驱动机构包括上发球轮驱动电机10和下发球轮驱动电机14，发球轮支架驱动机构包括上、下角度偏转电机12。上发球轮9和上发球轮驱动电机10设置于第一球轮支架11的第一端，下发球轮13和下发球轮驱动电机14设置于第一球轮支架11的第二端，上下角度偏转电机12设置于上发球轮9和下发球轮13之间，上下角度偏转电机12的输出轴驱动该第一球轮支架11旋转。
参见图2，在发球工作模式时，搅拌电机4驱动搅拌盘3转动，搅拌盘3带着出球孔25中的球旋转，当其中一个球转到下球孔20时，球会由于重力作用落入发球导球部18中。发球导球部18与第一球轮支架11连接，上发球轮9固定于上发球轮驱动电机10的输出端并由电机驱动顺时针旋转，下发球轮13固定于下发球轮驱动电机14输出端并由电机驱动逆时针旋转。上发球轮9和下发球轮13外表面最近处的距离小于球体19的直径，当球体19进入到两个发球轮中间时，球体19经过上发球轮9和下发球轮13的共同摩擦和挤压，从而被发射出去，实现发球功能。
进一步的，上发球轮9和下发球轮13的外表面材质可以为聚氨酯、橡胶、或者其他类似材料或者材料的组合。
进一步的，所述发球轮支架驱动机构还包括左、右角度偏转电机6。该左、右角度偏转电机6优选的固定于所述球筐的底板5上，可替代的，该左右角度偏转电机6也可以被固定于上部机体1或下部机体8的其他位置处，既可以固定于发球轮的上方，又可以固定于发球轮的下方，本实施例不做具体限定。
进一步的，捡发球一体机还包括第二球轮支架7，第二球轮支架7的上端连接左右角度偏转电机6的输出轴，第二球轮支架7的下端固定有所述上下角度偏转电机。
可选的，第一球轮支架11中间与上下角度偏转电机12的输出端固定，上下角度偏转电机12固定于第二球轮支架7底部，第二球轮支架7可以是L型支架，上下角度偏转电机12驱动第一球轮支架11旋转，从而可以调整发球俯仰角度。左右角度偏转电机6固定于球筐的底板5上，或上、下部机体的其他位置，其驱动输出轴与L型支架的顶部连接，这样可以控制L型支架左右旋转，从而可以调整发球的左右角度。
可选的，第二球轮支架7还可以是其他造型的支架，第二球轮支架7的一端也可以不连接在上下角度偏转电机12上，而直接连接到第一球轮支架11上，只要第二球轮支架7能在左右角度偏转电机6的带动下控制第一球轮支架11偏转即可。
可选的，上述各类电机可以是伺服电机、步进电机、舵机、减速电机、有刷/无刷电机等。
可选的，上、下发球轮的驱动电机和上、下发球轮可以安装于第一球轮支架11的同侧或者两侧，驱动电机和发球轮之间可加入轴承、联轴器、同步带等进行驱动。基于相同的原理，上下角度偏转电机12和第一球轮支架11也可以安装于第二球轮支架7的同侧或者两侧，上下角度偏转电机12和第一球轮支架11之间也可以加入轴承，联轴器、同步带等进行驱动。
可选的，所述左右和俯仰角度调整方式由电机输出轴直接驱动，也可以通过齿轮、链条、同步带、蜗轮蜗杆、多连杆机构、轴承、联轴器等实现，本实施例不做具体限定。
参见图3，在捡球工作模式时，上下角度偏转电机12驱动第一球轮支架11逆时针旋转，使得下发球轮13进入到图3中捡球位置，此位置下发球轮13的下边缘与地面16距离小于球体19的直径，在下发球轮13右侧为固定的捡球导向槽的下槽17，此时下发球轮13作为捡球轮使用。
一体机底部配有方便移动的轮子15，当一体机移动到处于地面16的球体19上方附近时，且球体19处于下发球轮13下边缘附近时，会被逆时针旋转的下发球轮13摩擦和压缩，从而进入捡球导向槽的下槽17，压缩和摩擦后，球体19变为压缩状态，在捡球导向槽的下槽17与下发球轮13之间对应的弧线部分，捡球导向槽的下槽17距离下发球轮13的外表面小于球体19的直径，从而球体19被逆时针旋转的下发球轮13和捡球导向槽的下槽17一起挤压和摩擦，使得球体19获得速度沿着捡球导向槽下槽17上升到捡球导向槽的上槽2，捡球导向槽的上槽2顶端为圆弧形，球体19经过捡球导向槽的上槽2顶端后进入球筐，完成捡球过程。
需要说明的是，球的上升速度是由于球被挤压和摩擦产生的，可以通过调节作为捡球轮的下发球轮13的转速来控制，或者通过调节捡球导向槽的下槽17与作为捡球轮的下发球轮13的相对距离来控制。进一步的，捡球导向槽的下槽17和捡球导向槽的上槽2为凹槽型结构，其宽度大于球的直径，槽截面可为开口方形，也可为圆弧形，或者多边形。凹槽可以是全封闭的管道或者半封闭管道或者类似结构。捡球导向槽的下槽17从下到上(从水平到垂直)的弧度可以是一段或多段圆弧、一段或多段折线、或者圆弧和折线的组合。
进一步的，捡球导向槽的上槽2的顶端有一处弧形挡板(也可为斜板或其他形状)，目的是实现将球导入球筐中。可选的，该弧形挡板可以是
一段或多段圆弧、一段或多段折线、或者圆弧和折线的组合。
可选的，捡球导向槽的上槽2和捡球导向槽的下槽17，共同组成的捡球导向槽，可以是分段式的，也可以是一体式。
可选的，上发球轮9和下发球轮13可以是圆柱形轮。更优选的，可以将圆柱形轮的周向转动面设置为带有一个或多个凹槽结构，这样上发球轮9和下发球轮13对球体19的接触面积会更大，发球或捡球时不容易发生打滑现象。
综上，本实用新型的捡发球一体机能够使球体在捡球导向槽的底部被捡起，在捡球轮和槽底面共同摩擦和挤压下，获得速度后沿着捡球导向槽的下槽17和捡球导向槽的上槽2进入球筐。由于本实用新型未采用滚动挡板捡球结构，因此可以实现快速捡球。
本实用新型的另一实施例，在上一实施例的捡发球一体机中设置独立于发球部的捡球部，这样既简化了发球部的状态切换过程，又可以令发球部和捡球部互不干扰的独立工作。
参见图5、6，独立的捡球部包括：捡球轮23、捡球轮支架21和捡球轮驱动电机24。所述捡球轮23设置于所述捡球导向槽的下槽17的底部入口处，所述捡球导向槽的下槽17的底部入口贴近地面。在捡球时，捡球轮23由捡球轮驱动电机24驱动逆时针旋转，捡球轮驱动电机24固定于捡球支架21底部，捡球支架21为L型支架，其顶部固定在上部机体1或下部机体8的适当位置处，优选的，捡球支架21的顶部固定在球筐的底板5上。
可选的，所述捡球轮23可由捡球轮驱动电机24输出轴直接驱动，也可以通过齿轮、链条、蜗轮蜗杆、多连杆机构、轴承、联轴器、同步带等传动机构间接实现，本实施例不做具体限定。此外，捡球轮23可以通过轴
承，联轴器、同步带等机构与捡球支架21连接。
可选的，捡球轮23可以是圆柱形轮。更优选的，可将圆柱形轮的周向转动面设置为带有一个或多个凹槽结构，这样捡球轮23对球体19的接触面积会更大，捡球时不容易发生打滑现象。
作为另一优选实施方式(附图未示出)，捡球轮的轮宽可以制作的较为宽大，例如将捡球轮的轮宽设置为与下部机体8的宽度近似，并容纳于下部机体8内，捡球导向槽的槽口宽度设置为与捡球轮的轮宽匹配，例如槽口宽度能够覆盖住捡球轮的轮宽。所述捡球轮支架设置在下部机体8的两侧，捡球轮的轮轴直接或通过轴承支撑在所述捡球轮支架上。捡球轮驱动电机通过齿轮、链条、蜗轮蜗杆、多连杆机构、轴承、联轴器、同步带等传动机构驱动所述捡球轮转动，捡球轮驱动电机可以设置在下部机体的适当位置处，不妨碍捡球轮转动即可。该实施方式相比于图5、6实施方式而言具有更高的捡球效率。
需要指出的是，本实施例由于同时具有发球部和独立的捡球部，发球部的下发球轮13无需偏转至捡球导向槽的下槽17的入口处作为捡球轮使用。需要注意的是，独立的捡球部和捡球导向槽的下槽17的安装位置应尽量远离发球部，以避免妨碍到发球部的正常操作。
以上描述仅为本实用新型的较佳实施例。本领域技术人员应当理解，本实用新型中所涉及的公开范围，并不限于上述技术特征的特定组合而成的技术方案，同时也应涵盖在不脱离上述公开构思的情况下，由上述技术特征或其等同特征进行任意组合而形成的其它技术方案。例如上述特征与本实用新型中公开的(但不限于)具有类似功能的技术特征进行互相替换而形成的技术方案。
