该发明公开了一种水稻播种流水线上的钵盘自动放盘机构。包括曲柄机构、摇杆、连杆、机架、滑块、齿条、两个凸轮、第一齿轮、两个机械臂、两根齿条顶杆、一对第二齿轮、两个机械手、加强杆、一对第三齿轮、两根双面齿条、两对第四齿轮和两个手爪。曲柄机构的曲柄带动摇杆摆动,使滑块作往复运动,实现机械臂的来回摆动。顶杆安装在机械臂内,相对机械臂滑动,顶杆一端与凸轮接触,另一端是齿条与机械臂上的齿轮啮合。同轴一对齿轮与双面齿条啮合,驱动机械手张开和闭合;曲柄转动一周,机械臂转动一定角度,到钵盘堆放位置机械手抓取钵盘后,机械臂转动回到初始位置,机械手松开把钵盘放置到播种流水线上,减少人工操作,提高水稻机械化播种效率。
The invention discloses a bowl disk automatic tray mechanism on a rice sowing pipeline. Including a crank mechanism, a rocker, a connecting rod, a frame, a slider, a rack, two cams, a first gear, two arms, two rack rams, a pair of second gears, two manipulators, A pair of third gears, two double-sided racks, two pairs of fourth gears, and two claws. Crank cranks crank rocker swing, so that the slider reciprocating motion, to achieve swing back and forth manipulator. The plunger is mounted in the robot arm and slides relative to the robot arm. One end of the plunger is in contact with the cam, and the other end is a rack engaged with the gear on the robot arm. A pair of coaxial gears mesh with the double-sided rack to drive the manipulator to open and close; after the crank rotates for one week, the manipulator rotates for a certain angle, and after the manipulator grasps the bowl plate, the manipulator rotates back to the initial position, Loosen the bowl dish placed on the sowing line, reduce manual operation, improve the mechanization of rice sowing efficiency.
