    摘要:

    為實(shí)現(xiàn)蔗種精準(zhǔn)橫向播種,設(shè)計(jì)了一種預(yù)切種式甘蔗橫向排種器。通過對(duì)蔗種在排種器中的運(yùn)動(dòng)分析和基于Recurdyn軟件的排種器運(yùn)動(dòng)仿真,探究排種器傳送鏈軸轉(zhuǎn)速、提升傳送鏈傾角和集蔗箱傾角對(duì)排種性能的影響。利用自制的簡(jiǎn)易鏈?zhǔn)礁收崤欧N器試驗(yàn)平臺(tái),對(duì)排種器的一級(jí)鏈軸轉(zhuǎn)速、傳送鏈傾角和集蔗箱傾角等參數(shù)進(jìn)行試驗(yàn)研究,結(jié)果表明:傳送鏈傾角和一級(jí)鏈軸轉(zhuǎn)速對(duì)排種性能具有極顯著的影響,集蔗箱傾角對(duì)排種性能的影響不顯著;排種性能的最優(yōu)參數(shù)組合為傳送鏈傾角55°、鏈軸轉(zhuǎn)速9.16r/min、集蔗箱傾角45°。室內(nèi)驗(yàn)證試驗(yàn)表明,排種器的合格率為92.6%、漏植率為5%、重植率為3.2%,說明排種器能有效避免排種過程的重植和漏植現(xiàn)象,減少播種過程的耗種量。田間驗(yàn)證試驗(yàn)表明,排種方向合格率93.37%,排種株距合格率90.33%,排種株距在33~49.5cm的合理株距范圍內(nèi),實(shí)現(xiàn)了雙蔗芽蔗種的精準(zhǔn)橫向播種。

    Abstract:

    In order to realize the accurate horizontal seeding of sugarcane seeds, a kind of pre-cutting sugarcane transplanter was designed. The influence that the speed of seed metering chain, angle of chain and angle of cane box made on the performance of planting was confirmed by analyzing the movement of the planting device and the simulation study. By using the sugarcane planter test platform, the physical experiments of the first-stage chain speed, the angle of conveyor chain inclination and the cane box inclination angle of planting device were carried out. The experiment results showed that the angle of chain had a very significant impact on the performance of planter. The speed of chain shaft and angle of box had no significant effect on the performance of planter. The order of primary and secondary factors affecting performance was the angle of conveyor chain, rotation speed of chain shaft, and inclination angle of cane box. There was no interaction between these factors. The optimal value of chain angle was 55°, the best value of chain shaft speed was 9.16r/min, the best inclination angle of cane box was 45°. In performance verification experiments, missing seed rate was 5%, replanting rate was 3.2% and pass rate was 92.6%. The reseed phenomenon during the planting can be effectively avoided. The seed consumption can be reduced during the planting process, and the missing seed phenomenon can also be avoided during the planting process. The qualified rate of seed metering direction was 93.37%, and the qualified rate of seed metering plant spacing was 90.33%. The spacing of planting was between 33cm and 49.5cm (a reasonable range), and the precise horizontal planting of double-buds section sugarcane can be realized.
