精准插秧机秧盘连续输送与穴孔同步对中装置

Seedling tray continuous feed and synchronous cave-hole alignment device for precision paddy seedling transplanter

采用电磁换向阀和气缸相结合的控制方法,研制了一种新型的秧盘连续输送与穴孔同步精准播种对中装置。双层秧盘供送机构通过气动实现秧盘依次供送。秧盘输送同步对中机构由限位气缸控制。当穴孔信号对准后,释放秧盘实现秧盘穴孔与气吸滚筒吸孔的投种点精准对中。试验结果表明,采用双层秧盘供送机构和同步对中机构能有效地降低劳动强度,保证投种定位准确,提高播秧品质。本文的研究为水稻精准育秧成套技术装备开发提供了参考。

A new type device for seedling tray continuous feed and synchronous cave-hole alignment was developed for a precision seedling transplanter using the combination of an electromagnetic directional valve and a pneumatic cylinder. A two-layer tray feed mechanism accomplishes the tray feed in turn pneumatically. The synchronous alignment of the tray feed is controlled by a position limitation cylinder. The accurate alignment of the tray cave and the pneumatic cylinder seedling sucking hole was realized by releasing the tray after receiving the cave-hole alignment signal. Experiment results proved that adopting the two-layer tray feed and synchronous alignment device reduces the laboring intensity effectively, ensures the orientation precision of throwing seedling, improves the seedling transplonting quality, providing a reference for the development of the technology and equipment of paddy precision seedling transplanting.
