Description

一种收割播种一体化复式作业机 技术领域
本发明属于农业机械技术领域，尤其涉及一种收割播种一体化复式作业机。
背景技术
我国的冬油菜产区大多分布在长江流域，占总产的90％以上，主要以稻-油或稻-稻-油水旱轮作为主。长期以来，该区域播种受前茬作物收获农时、土壤黏重板结和分散田块等影响，油菜机械化水平低下进而导致生产成本高、效益低，制约了油菜产业的发展。提高我国油菜机械化播种水平是油菜种植节本增效的重要途径。
水稻一般在9～10月份成熟，恰恰与油菜的播种期重合，人们可以收割完水稻之后接着在田里种油菜。但是现有的油菜复式作业机械往往与拖拉机挂接，例如中国专利ZL200920066064.6，多功能油菜播种机，在联合收获机收获结束后，需要拖拉机带着油菜复式作业机械再次下地，完成油菜的施肥、旋耕、开沟、播种等作业，增加了农业机械的轧地次数，加强了土壤板结的程度，同时也增加了作业成本。因此，需要设计一种挂接联合收获机的油菜复式作业机，一次性完成水稻的收获和油菜的播种作业。

如图5和6所示，根据本实施例优选的，所述检测装置为拉绳式位移传感器16；所述拉绳式位移传感器16安装在控制联合收获机25的割台升降的油缸18的底座19上，拉绳式位移传感器16的拉绳24与输送槽34的底部连接。根据本实施例优选的，所述控制装置通过行程开关17与操作杆20连接。当所述割台9从A点下降到A＇点时，所述拉绳式位移传感器16的拉绳24从B点运动到B＇点。所述A点和A＇点分别是割台9能够正常工作的最高点和最低点。当割台9从上往下运动到A点，所述拉绳式位移传感器16的拉绳24缩短到B点，产生的信号控制电磁阀驱动第一液压马达5开始运转和第一油缸7由最短状态开始伸长；当所述割台9在A点和A＇点之间上下调整时，所述拉绳式位移传感器16的拉绳24在B点和B＇点之间运动，产生的信号控制电磁阀驱动所述第一油缸7伸长或缩短，以确保所述灭茬装置1相对地面的高度保持不变；当割台9从下往上运动到A点，所述拉绳式位移传感器16的拉绳24伸长到B点，产生的信号控制电磁阀驱动第一液压马达5停止运转和第一油缸7开始缩短至最短。所述行程开关17安装在控制脱粒清选等动力连接与断开的操作杆20上。当所述操作杆20被推倒，脱粒清选等动力连接开始工作，行程开关17打开，通过电磁阀控制驱动第二油缸12先伸到最长，第二液压马达11再开始运转；当所述操作杆20被拉起，脱粒清选等动力中断停止工作，行程开关17断开，通过电磁阀控制第二液压马达11先停止运转，然后第二油缸12再缩到最短。
本发明的工作原理如图7所示：
当所述割台9下降到A点以下，第一液压马达5运转，驱动灭茬装置1的灭茬刀21工作，第一油缸7伸到最长，在割台9下降和第一油缸7伸长的过程中，灭茬装置1绕第一铰接点22逆时针旋转；所述A点和A＇点分别是所述割台9能够正常工作的最高点和最低点，当所述割台9在A点和A＇点之间上下调整时，所述拉绳式位移传感器16的拉绳24在B点和B＇点之间运动，产生的信号控制电磁阀驱动所述第一油缸7伸长或缩短，以确保所述灭茬装置1相对地面的高度保持不变；推倒操作杆20，让第二油缸12先伸到最长，然后第二 液压马达11再开始运转，驱动施肥装置2、旋耕开沟装置3和油菜播种装置4工作，在第二油缸12伸长的过程中，机架10绕第二铰接点23顺时针旋转至水平。
当所述联合收获机25在田间正常行驶时，被联合收获机切割器割断的稻穗流入割台9内，剩下的高茎秆被灭茬装置1切割成低茎秆。稻穗经过脱粒清选，其余茎秆被碎草机13打碎抛洒至田间，覆盖在刚刚播下的油菜种子上面。浅松施肥铲26对灭茬后的种床带进行浅松作业，由施肥装置2排出的肥料经过排肥管27输送到浅松施肥铲26后面，随着机具的前进，肥料被深埋在土壤中。紧接着，后面的旋耕开沟装置3对种床厢面进行旋耕和在中间开畦沟作业，旋耕时抛起的土被挡土板30遮住，开沟刀15开畦沟时抛出的土壤覆盖在粉粹的茎秆上面。最后，开种沟器28对旋耕后的种床厢面进行开种沟作业，由油菜播种装置4排出的油菜种子经过排种管29输送到开种沟器28内部，然后被粉碎的茎秆和开畦沟时抛出的土壤覆盖在下面。
当联合收获机25行驶到田间地头遇到田埂、转弯或粮箱已满需要卸粮时，机手控制割台9上升到A点以上，第一液压马达5停止运转，灭茬刀21停止工作，第一油缸7缩到最短，在割台9上升和第一油缸7缩短的过程中，灭茬装置1绕第一铰接点22顺时针旋转；拉起操作杆20，让第二液压马达11先停止运转，使施肥装置2、旋耕开沟装置3和油菜播种装置4停止工作，然后再让第二油缸12缩到最短，在第二油缸12缩短的过程中，机架10绕第二铰接点23逆时针旋转。
实施例2
本实施例2与实施例1的主要区别在于，所述联合收获机25为小麦联合收获机。
