工作时,将大蒜定向投种机构安装于取种机构下方,且使得取种机构取出的蒜种落入鳞芽调整机构I17中,转盘电机10带动转盘旋转45°,视觉传感器1获取蒜种在鳞芽调整机构I17中的图像信息,并将图像信息上传至控制器13,同时,转盘电机10旋转90°,带动鳞芽调整机构I17旋转至鳞芽调整机构三15的位置,当需要调整鳞芽方向时,电磁铁7动作,使得鳞芽调整机构I17自转180°实现蒜种鳞芽方向调整,转盘电机10旋转90°,带动鳞芽调整机构I17旋转至鳞芽调整机构Ⅴ16的位置,在导向板11的作用下,鳞芽调整机构I17上部倾斜,挡板4打开,使得蒜种鳞芽以向上方向落入导种管5中,完成定向投种,在此过程中,位置传感器19检测鳞芽调整机构16的位置,当检测到鳞芽调整机构16时,转盘电机10停止动作。
最后应说明的是:以上所述仅为本发明的优选实施例而已,并不用于限制本发明,尽管参照前述实施例对本发明进行了详细的说明,对于本领域的技术人员来说,其依然可以对前述各实施例所记载的技术方案进行修改,或者对其中部分技术特征进行等同替换。凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
