    摘要:

    設(shè)計(jì)了以電磁力為動(dòng)力源,與小區(qū)育種播種機(jī)相配套的自動(dòng)供種系統(tǒng),并對(duì)關(guān)鍵部件的結(jié)構(gòu)尺寸以及運(yùn)動(dòng)進(jìn)行分析,該系統(tǒng)通過共軸雙盤格供種結(jié)構(gòu),可以連續(xù)完成34個(gè)小區(qū)的供種。通過對(duì)油菜種子在不同供量與給定的調(diào)整時(shí)間內(nèi)連續(xù)供種試驗(yàn),表明4種供量的油菜種子隨著調(diào)整時(shí)間的增大,調(diào)整量與供種均勻性變異系數(shù)均減小,在8s時(shí),供種均勻性差異的波動(dòng)趨于平緩,其供量為7 g油菜種子的供種均勻性變異系數(shù)最小,為7.59%,在該供量下,油菜種子的損失率為0.97%,供種誤差均小于3 mm。通過與人工等量隔種對(duì)比試驗(yàn)表明,在2種供種系統(tǒng)中,4種供量的油菜種子供種均勻性差異均小于1.5%。

    Abstract:

    Automatic supplying rape seed system for plot seeder was designed. It took electromagnetic force as power source and went with plot seeder. Key parts of structure and motion were analyzed. Automatic supplying seed system was able to accomplish supplying seed for 34 plots. By the supplying seed experiment without interruption at the different supply amount in the given time, the result showed that adjusting value and uniformity CV decreased with increasing of time. The uniformity CV was at the minimum range when the time was 8s and the minimum uniformity CV for rape seed was 7.59% at supply amount of 7 g. Loss rate for rape seed was 0.97% and error of supply seed was less than 3 mm. Compared with manual operation, the uniformity CV between the two metering devices was blow 1.5% for rape seed.
