本发明实施例公开了一种自动上苗系统,通过传送导线将传送托架上的秧盘与秧箱准确对接,使得秧盘可以适应秧箱的不同位置,以便将秧盘中的 秧苗准确的传送到秧箱中,无需中断插秧作业,提高了插秧作业效率。下面对本发明实施例进行详细说明。

参见图1-图6(d),本发明实施例提供的自动上苗系统包括秧盘传送装置安装架2和至少一组上苗装置,每组上苗装置包括上苗主托板3、传送托架5、传送托架回位器6、秧苗阻隔门7、传送导线9、传送导线回收驱动器10和秧箱14。
继续参见图1-图6(d),对于任一组上苗装置,为了使上苗装置可以与秧箱14对接,设置上苗主托板3转动连接于秧盘传送装置安装架2,传送托架回位器6安装于上苗主托板3,传送托架回位器6的伸缩绳与传送托架5的一端连接,通过传送托架回位器6控制伸缩绳拉着传送托架5沿伸缩绳前后运动以便于与秧箱14对接。
传送托架5上端安放有秧盘13,为了使秧盘13可以与秧箱14准确对接,设置传送托架5的另一端与传送导线9的一端连接,为了防止秧盘13上的秧苗掉落,传送托架5的另一端的上表面设置有秧苗阻隔门7,传送导线9的另一端与传送导线回收驱动器10的输出端连接,传送导线回收驱动器10与秧箱14连接,通过传送托架回位器6、传送托架5和传送导线9建立该上苗装置与秧箱14之间的柔性连接。
对于任一组上苗装置,传送导线回收驱动器10收紧传送导线9,使得传送导线9带动上苗主托板绕转轴旋转至第一预设角度,传送导线9拉动传送 托架5相对上苗主托板3运动,传送导线9带动传送托架5运动至与秧箱14对接的对接位置,也就是图4中传送托架5所在的位置,秧苗阻隔门7开启,由于重力作用,秧盘13上的秧苗转移至秧箱14中。
由上述内容可知,本实施例中不再采用固定的对接的方式,而是通过传送导线将秧盘与秧箱对接,传送导线回收驱动器收紧传送导线,通过传送导线拉动传送托架带动传送托架上的秧盘与秧箱准确对接,使得秧盘可以适应秧箱的不同位置,以便将秧盘中的秧苗准确的传送到秧箱中。
参见图1-图6(d),每组上苗装置还可以包括主托板限位器4、秧苗阻隔门开启器8、传送导线回收线轴11、安装板12、限位器锁止件、第一遮挡杆15、秧苗检测传感器和位置传感器。
参见图1,由于驾驶员位于插秧机1的车架前端,因此,将自动上苗系统设置于插秧机1的车架后端,具体的,将秧盘传送装置安装架2安装于插秧机1的车架后端的上表面。
对于任一组上苗装置,为了确定安装于传送托架5的秧盘13上是否装载有秧苗,在上苗主托板3的上表面设置有秧苗检测传感器。主托板限位器4的一端连接秧盘传送装置安装架2的一端,另一端连接限位器锁止件和上苗主托板3的一端,为了将传送托架5固定于上苗主托板3上,上苗主托板3与主托板限位器4的连接处设置有第一通孔,限位器锁止件穿过第一通孔伸出上苗主托板3的上表面,并嵌入传送托架5相应的锁止孔17内。
上苗主托板3的另一端通过转轴转动连接于秧盘传送装置安装架2的另一端。上苗主托板3可以绕着转轴旋转,参见图2,上苗主托板3位于初始位置并未进行旋转,此时,主托板限位器4处于收缩状态,参见图3,上苗主托板3绕着转轴顺时针转动到无法转动的位置,主托板限位器4处于伸直状态。
继续参见图2,对于任一组上苗装置,主托板限位器4可以包括限位拉线41和限位器底座及限位块42,限位拉线41的一端连接秧盘传送装置安装架2的一端,另一端连接限位器锁止件和限位块42,限位块42与限位器底座之间设置有弹性元件,弹性元件在限位拉线未被拉伸到预设位置前处于伸出状态,并通过上苗主托板3上的第一通孔连接上苗主托板3的一端。在图2所示状态下,限位拉线41处于收缩状态,在图3所示状态下,限位拉线41 处于伸直状态。
继续参见图2-图4,为了使上苗装置可以与秧箱14对接,在上苗主托板3的一端的上表面设置有阻隔板16,传送托架回位器6安装于阻隔板16的外侧,传送托架回位器6的伸缩绳穿过阻隔板16的通孔与传送托架5的一端连接,通过传送托架回位器6控制伸缩绳拉着传送托架5沿伸缩绳前后运动以便于与秧箱14对接。
在上苗装置有多组时,各组上苗装置并排设置,位于中间的几组上苗装置的传送托架5与上苗主托板3分离后,有相邻的上苗主托板3及传送托架5支撑,不会脱落,而位于插秧机的左右边缘的传送托架5如果向外侧移动会有翻落的风险,因此为了防止在上苗装置与秧箱14对接时,设置于左右边缘的上苗装置的传送托架5从上苗主托板3上脱落,将设置于左右边缘的上苗装置的上苗主托板3的宽度设置为大于传送托架5的宽度,同时传送托架回位器6安装在上苗主托板3的内侧。由此,对于设置于左右边缘的上苗装置,通过设置上苗主托板3的宽度大于传送托架5的宽度的方式,保证在上苗装置与秧箱14对接时,处于左右边缘的传送托架5不会从上苗主托板3上脱落。
继续参见图2-图6(d),为了在传送状态下,装载秧苗的秧盘13不会从传送托架5上掉落,将秧盘13的下表面设置有第一凹槽,传送托架5的上表面设置有第二凹槽,上苗主托板3和传送托架5位于初始位置,第一遮挡杆15安装于第二凹槽内,也就是上苗主托板3和传送托架5位于图2所示位置,上苗主托板3和传送托架5位于图3所示位置,第一遮挡杆15突出传送托架5的上表面并嵌入第一凹槽内,使得秧盘13不会从传送托架5上掉落。
继续参见图2-图6(d),为了使第一遮挡杆15可以突出传送托架5的上表面并嵌入第一凹槽内,设置传送导线9的一端与第一遮挡杆15连接,另一端穿过安装板12上的通孔安装于传送导线回收线轴11,传送导线回收线轴11和传送导线回收驱动器10的输出端连接,传送导线回收线轴11和传送导线回收驱动器10均安装于安装板12,示例性的,传送导线回收线轴11和传送导线回收驱动器10可以通过连接机构均安装于安装板12的下表面,也可以安装于安装板12的上表面,优选为安装于安装板12的下表面,安装板12安装于秧箱14的下表面,在图3所示状态下,传送导线回收线轴11收紧传送导线9,使得传送导线9拉动安装于第二凹槽内的第一遮挡杆15突出传 送托架5的上表面并嵌入第一凹槽内。
继续参见图2-图4,秧苗阻隔门开启器8安装于安装板12的上表面设置的第三凹槽内。为了检测秧箱14中的秧苗的数量,将位置传感器安装于秧箱14中。
对于任一组上苗装置,秧苗检测传感器检测放置于传送托架5的秧盘13上是否装载有秧苗,当秧盘13上有秧苗时,说明此时用于补充到秧箱14中的秧苗已经准备完成,秧苗检测传感器发送第一指令至传送导线回收驱动器10,传送导线回收驱动器10接收第一指令获知用于补充到秧箱14中的秧苗已经准备完成。位置传感器检测秧箱14中的秧苗存量,当秧苗存量小于预设值时发送第二指令至传送导线回收驱动器10,秧苗存量小于预设值说明秧箱14中的秧苗数量较少,需要补充秧苗,传送导线回收驱动器10接收第二指令获知秧箱14需要补充秧苗。
因此,传送导线回收驱动器10接收到第一指令和第二指令时,获知秧箱14需要补充秧苗且用于补充到秧箱14中的秧苗已经准备完成,此时即可将秧苗补充到秧箱14,因此,传送导线回收驱动器10控制传送导线回收线轴11收紧传送导线9,使得传送导线9拉动安装于第二凹槽内的第一遮挡杆15突出传送托架5的上表面并嵌入第一凹槽内,传送导线9带动上苗主托板3绕转轴旋转至第一预设角度,限位器锁止件离开锁止孔17,上苗主托板3拉伸主托板限位器4至支撑位置,也就是图3中主托板限位器4所在的位置,主托板限位器4支撑上苗主托板3,由于限位器锁止件离开了锁止孔17,因此,传送导线9可以拉动传送托架5运动带动秧盘13运动至与秧箱14对接的对接位置,也就是图4中传送托架5所在的位置。
传送托架5到达对接位置时,说明此时可以将秧苗补充到秧箱14中,秧苗阻隔门开启器8与秧苗阻隔门7接触并推动秧苗阻隔门7开启,由于重力的作用,秧盘13上的秧苗转移至秧箱14中。当然,秧苗阻隔门开启器8也可以为电控形式,秧苗阻隔门开启器8与秧苗阻隔门7电连接,传送托架5到达对接位置时,秧苗阻隔门开启器8控制秧苗阻隔门7开启,本发明对秧苗阻隔门开启器8的形式并不做任何限定。
位置传感器检测秧箱14中的秧苗存量不小于预设值时发送第三指令至传送托架回位器6,秧苗存量不小于预设值说明秧箱14中的秧苗的数量较多, 秧苗补充完成,传送托架回位器6接收第三指令,获知秧苗补充完成,收紧伸缩绳,使得伸缩绳拉动上苗主托板3和传送托架5回到初始位置,上苗主托板3压缩主托板限位器4至起始位置,也就是上苗装置又回到图2中的状态。
由上述内容可知,本实施例的传送导线回收驱动器接收到第一指令和第二指令时,控制传送导线回收线轴收紧传送导线,通过传送导线拉动传送托架运动至与秧箱对接的对接位置,然后秧苗阻隔门开启器推动秧苗阻隔门开启,在重力的作用下使得传送托架上的秧盘中的秧苗转移至秧箱中,达到了自动将秧盘中的秧苗放置到秧箱中的目的,无需人为,减少了人力劳动,提高了上苗的工作效率。
同时,本发明实施例提供的自动上苗系统具有很好的跟随性,即在插秧作业过程中就可以传送秧苗到秧箱中,无需中断插秧作业。
本发明实施例中的秧苗阻隔门7是通过电控进行开启,当然也可以采用机械式进行开启,本发明实施例对此并不做任何限定。对于任一组上苗装置,秧苗阻隔门7的开启方式包括向上开门式、向下开门式或两侧开门式中的一种。
对于任一组上苗装置,当秧苗阻隔门7的开启方式为向上开门式时,在上苗主托板3和传送托架5位于初始位置时,可以设置秧苗阻隔门7距离秧盘13第一预设距离,秧苗阻隔门7向上开启至预设位置。
对于任一组上苗装置,当秧苗阻隔门7的开启方式为向下开门式时,需要在秧苗阻隔门7与传送托架5的另一端的边缘之间的传送托架5上留出一部分面积用来放置开启后的秧苗阻隔门7,即秧苗阻隔门7距离传送托架5的另一端的边缘第二预设距离,位于秧苗阻隔门7与传送托架5的另一端的边缘之间的传送托架5的上端面设置有第四凹槽,秧苗阻隔门7向下开启并嵌入第四凹槽中。
对于任一组上苗装置,当秧苗阻隔门7的开启方式为两侧开门式时,秧苗阻隔门7包括左门板和右门板,左门板向左侧开启,右门板向右侧开启。通过左门板和右门板的开启实现秧苗阻隔门7的开启。
继续参见图6(a)-图6(d),对于任一组上苗装置,无论在秧盘13的下表面是否设置有第一凹槽,为了防止秧盘13从传送托架5上脱落,设置传 送托架5的左右两侧分别转动连接有第二遮挡杆51和第三遮挡杆52,设置传送导线9包括第一传送导线91和第二传送导线92,设置安装板12上的通孔包括第二通孔121和第三通孔122,第一传送导线91的一端与第二遮挡杆51连接,并穿过第二遮档杆51与第一遮挡杆15连接,另一端穿过第二通孔121安装于传送导线回收线轴11,第二传送导线92的一端与第三遮挡杆52连接,另一端穿过第三通孔122安装于传送导线回收线轴11。
传送导线回收驱动器10接收到第一指令和第二指令时,控制传送导线回收线轴11收紧第一传送导线91和第二传送导线92,使得第一传送导线91拉动第二遮挡杆51转动至第二预设角度,并拉动安装于第二凹槽内的第一遮挡杆15突出传送托架5的上表面并嵌入第一凹槽内,第二传送导线92拉动第三遮挡杆52转动至第二预设角度。
由此,通过设置在传送托架5的左右两侧设置第二遮挡杆51和第三遮挡杆52的方式,防止秧盘13从传送托架5上脱落。
由于如果通过人力将秧盘13放置到传送托架5上,将耗费较多人力,因此,本发明实施例中的每组上苗装置还可以包括秧盘托架和秧盘托架驱动器,对于任一组上苗装置,秧盘托架驱动器安装于秧盘传送装置安装架2,秧盘托架驱动器的输出端与秧盘托架连接,秧盘托架一般设置在秧盘的补充入口处,方便将准备好的秧盘放置到秧盘托架上,秧盘托架驱动器驱动秧盘托架将秧盘托架上的秧盘13传送至传送托架5上。
由此,通过设置秧盘托架和秧盘托架驱动器的方式,将秧盘自动传送至传送托架5上,减少了人力,提高了工作效率。
由于如果通过人力将秧苗放置至各组上苗装置的秧盘13中,将耗费较多人力,因此,本发明实施例中的自动上苗系统还可以包括横向推送装置,横向推送装置包括支撑架、传送带和电机,支撑架安装于秧盘传送装置安装架2,传送带安装于支撑架,电机的输出端与传送带连接,传送带传送秧苗至各组上苗装置的秧盘13中。当然,此处的传送带也可以替换为链条,本发明对此并不做任何限定。由此,通过设置横向推送装置的方式,将秧苗自动放置至各组上苗装置的秧盘13中,减少了人力,提高了工作效率。
