需要说明的是，在不冲突的情况下，本申请中的实施例及实施例 中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
图1-图3示出了本申请实施例提供的播种墙运输小车的示例性结构100。
如图1-3所示，本申请实施例提供了一种播种墙运输小车，播种墙运输小车的底盘101顶面设有货物传输装置102，底盘101的底面设有小车驱动装置103；小车驱动装置103上设有同步带轮104，在播种墙运输小车的运动过程中，同步带轮104在小车驱动装置103驱动下与设置于播种墙上的同步带滚动配合以带动播种墙运输小车沿同步带运动，货物传输装置102和小车驱动装置103通过设置于播种墙运输小车上的集电器105与设置于播种墙上的滑触线106电连接。
本申请的播种墙运输小车上的同步带轮104与播种墙上的同步带114配合，以使得播种墙运输小车在播种墙上运动，增大了播种墙运输小车在播种墙上的摩擦力，可以让播种墙运输小车在播种墙上获得更大的加速度与减速度，进而提升运输物的运输速率。
为了进一步提高同步带轮104与同步带114的配合程度，同步带114可以采用齿条皮带，同步带轮104与齿条皮带啮合连接，进一步提高同步带114与同步带轮104之间的摩擦力，在小车驱动装置103可提供的动能下，尽可能的使得播种墙运输小车具有更大的加速度和减速度，进一步提升运输物的运输速率。
本实施例中，货物传输装置102和小车驱动装置103通过集电器105与滑触线106连接，用于接收滑触线106传输的电能和信号，以实现货物传输装置102和小车驱动装置103的启停。同步带114张紧于 播种墙上，同步带轮104与同步带114配合，实现播种墙运输小车的快速启停。本实施例中，可以采用电机绝对值编码器进行播种墙运输小车在播种墙上的定位。
作为示例，滑触线106中的电能输送线路将接收的电能提供装置提供的电能传输至货物传输装置102和小车驱动装置103；滑触线106中的控制信号输送线路将接收的控制装置提供的控制信号传输至货物传输装置102和小车驱动装置103。控制装置接收检测装置的检测信号，并根据检测信号做出针对货物传输装置102和小车驱动装置103的启停控制。
货物传输装置102可以是进行货物输送任务的任意输送装置。作为实例，货物传输装置102可以是滚筒输送机。
小车驱动装置103是为播种墙运输小车提供动力的动力装置，作为示例，小车驱动装置103可以是电动机。
在本实施例的一些可选的实现方式中，沿播种墙运输小车的运动方向，在同步带轮104的两侧设有同步带转向轮107。作为示例，同步带轮104的两侧分别设置一个同步带转向轮107。播种墙上的同步带114的一端固定于播种墙上的一端，同步带114的另一端依次绕过一个同步带转向轮107的底端、同步带轮104的顶点、另一个同步带转向轮107的底端并固定与播种墙上的另一端。同步带在同步带轮104和同步带转向轮107出构成U形，在同步带114张紧于播种墙上的基础上，使得同步带114与同步带轮104具有更大的接触面积，进而同步带114与同步带轮104之间具有更大的摩擦力，尽可能的使得播种墙运输小车具有更大的加速度和减速度，进一步提升运输物的运输速率。
在本实施例的一些可选的实现方式中，底盘101的底面设有导向轮113，导向轮113与播种墙上的导轨115滚动配合。通过导向轮113与播种墙上的导轨115的配合，使得导向轮113沿导轨115运动，提高了播种墙运输小车在播种墙上运动过程中的稳定性。
在本实现方式中，导向轮113包括：竖直方向导向轮和水平方向导向轮；竖直方向导向轮的转动轴垂直于水平方向导向轮的转动轴。竖直方向导向轮用于控制播种墙运输小车在轨道115上的平面运动，防止竖直方向上的颠簸；水平方向导向轮用于在播种墙运输小车运动过程中，防止播种墙运输小车与轨道115碰触造成播种墙运输小车的左右晃动。如此，通过竖直方向导向轮和水平方向导向轮，进一步提升了播种墙运输小车在播种墙小车上运动的稳定性。
在本实施例的一些可选的实现方式中，货物传输装置102为皮带输送机，皮带输送机的皮带的输送方向与播种墙运输小车在播种墙上的运动方向垂直。
在本实现方式中，皮带的数量为多条，多条皮带间隔设置；多条皮带的间隔处设有用于检测皮带上是否设有运输物的第一光电检测传感器108。无论运输物的厚度为多少，只要皮带输送机上存在运输物，设置于皮带间隔处的第一光电检测传感器108就能检测到该运输物，防止将第一光电检测传感器108设置于播种墙运输小车的侧面而检测不到较薄的运输物的情况，提高了播种墙运输小车关于运输物的检测准确性。
在本实施例的一些可选的实现方式中，播种墙运输小车上设有用于检测播种墙上的储物箱是否装满货物的第二光电检测传感器109。
在本实施例的一些可选的实现方式中，底盘的底面设有原点检测传感器110。
在本实施例的一些可选的实现方式中，底盘设有可拆卸电气板111，可拆卸电气板111与各传感器连接，并通过集电器105与滑触线106电连接。本实现方式中，可拆卸电气板上可设有控制装置，控制装置分别与上述传感器电连接，用于接收各传感器的检测信号，控制货物传输装置102和小车驱动装置103的启停。
作为示例，当控制装置接收到检测储物箱是否装满货物的第二光电检测传感器109关于播种墙上的一个储物箱装满运输物的检测信号，控制小车驱动装置103将播种墙运输小车运行至预设储物箱处；当播种墙运输小车运行至预设储物箱处时，控制装置控制货物传输装置102运行，将运输物转移至预设储物箱中。
在一些实施例中，沿播种墙运输小车的运动方向，在播种墙运输小车的两端设有挡板112。播种墙运输小车在播种墙上的运动过程中，挡板可以防止运输物的掉落。
以上描述仅为本申请的较佳实施例以及对所运用技术原理的说明。本领域技术人员应当理解，本申请中所涉及的发明范围，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发明构思的情况下，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。例如上述特征与本申请中公开的(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。
