    摘要:

    設(shè)計了一種能實(shí)現(xiàn)水稻精密育秧播種機(jī)缽體軟、硬秧盤穴孔底土壓實(shí)的通用裝置,，該裝置以AT89C51單片機(jī)為控制系統(tǒng)核心,，采用步進(jìn)電動機(jī)和送盤行程開關(guān)實(shí)現(xiàn)秧盤供送,，以及限位行程開關(guān)和對準(zhǔn)接近開關(guān)實(shí)現(xiàn)秧盤穴孔與壓實(shí)輥指對準(zhǔn),，壓實(shí)輥指與秧盤穴孔內(nèi)底土相互作用完成底土壓實(shí),。通過系統(tǒng)的試驗(yàn)研究,，確定了該裝置的最佳工作參數(shù),。壓實(shí)試驗(yàn)表明,，該系統(tǒng)能滿足秧盤穴孔底土壓實(shí)的工作要求，實(shí)現(xiàn)了穴孔與壓實(shí)輥指的精確對準(zhǔn)和底土壓實(shí)，當(dāng)生產(chǎn)率在500盤/h,、提前角對應(yīng)弧長為1mm時,，對準(zhǔn)率為98%，滿足缽體苗穴孔底土壓實(shí)的技術(shù)要求,；育秧試驗(yàn)表明,，增加穴孔底土壓實(shí)深度，可提高秧苗素質(zhì),，保持土壤根系堅實(shí)不散,，有利于栽插作業(yè)，壓實(shí)深度為6mm時效果最佳,。

    Abstract:

    The subsoil compaction device of bowl seedling tray cave-hole for rice seedling nursery planter was developed for soft and hard seedling tray. The device control system based on AT89C51 microcontroller used a stepping motor and a transporting-tray limit switch to control seedling tray feeding, and used a restrict limit switch and an align proximity switch to conduct seedling tray alignment and interaction between subsoil in the seedling tray cave-hole and the roller finger. With these steps, subsoil compaction was realized on this device. Through various testing on the compaction device, the optimum working parameters of the compaction device were obtained. The seedling tray alignment test showed that the system realized exact match between the seedling tray cave-hole and roller finger during the subsoil compaction operation at a productivity of 500 trays per hour and an advance angle arc length of 1mm, and the alignment rate of 98%, which met the technical requirements for subsoil compaction of bowl seedling tray cave-hole. The seedling nursery test showed that subsoil compaction of bowl seedling tray cave-hole improved the quality of seedlings and ensured the integrity and tightness of bowl seedling root-soil complex, which was most helpful for planting operations when the depth of subsoil compaction was 6mm.
