    摘要:

    超級稻育秧精密播種器中的精密播種部件采用氣吸滾筒和振動種盤的組合方式來控制精確吸種，種盤供種區(qū)域內(nèi)種子的“沸騰”狀態(tài)和蠕動狀態(tài)均與振動參數(shù)密切相關(guān)。本文結(jié)合供種區(qū)域不同的種層厚度以及氣動振動器的不同安裝位置測試了滾筒的吸種效果，并探討了超級稻育秧精密播種器中種盤振動特性對滾筒吸種效果的影響。試驗結(jié)果表明, 激振源安裝在種盤后方對播種精度最為有利，種層厚度為0.7cm、振動頻率為98Hz時吸種效果最佳，其合格率達(dá)93.118%。

    Abstract:

    The performance of fine-sucking seed was controlled by the combination mode of the vacuum cylinder (VC) and the vibrating seed plate (VSP) in the precision seedling planting parts for super hybrid rice. The ebullience and vibration of the seed close to VC in VSP were highly correlated with vibration parameters. The sucking-seed capability of VC was measured on conditions of the different seeds thickness and the installation position of vibrator, respectively. In addition, the vibration characteristic of VSP was studied. The results showed that the optimal performance is obtained when the air-style vibrator is at the rear of VSP, and the regular capability of fine-sucking seed depends on the given seeds thickness close to VC and the vibrator’s frequency in harmony. The prime performance comes to 93.118% when the optimum seeds thickness 0.7cm and frequency of vibration 98Hz.
