AI Technical Summary
Existing rice transplanters lack reliable automatic seedling replenishment devices for unmanned operation, which requires continuous manual intervention and makes it impossible to achieve fully unmanned operation, thus increasing labor costs.
An automatic seedling replenishment device for an unmanned rice transplanter was designed, including a seedling pushing mechanism, a seedling lowering plate replenishment mechanism, a navigation system, and multiple motor drive mechanisms. It realizes the automatic pushing, docking, and replenishment of seedlings. Through the linkage of components such as the scissor fork linkage, the seedling delivery ratchet, and the seedling blocking pull line, the accurate delivery and alignment of seedlings are ensured.
It achieves fully automated seedling replenishment in rice transplanter field operations, reduces labor costs, has a compact structure, high reliability, adapts to different soil and water conditions, and ensures the accuracy and reliability of seedling replenishment.
