    摘要:

    結(jié)合機(jī)械內(nèi)充種式排種器的結(jié)構(gòu)特點(diǎn)和氣吹式排種器的單粒留種原理，設(shè)計(jì)了一種機(jī)械氣力組合式玉米精密排種器。闡述了其基本結(jié)構(gòu)和工作原理，對關(guān)鍵部件進(jìn)行了設(shè)計(jì)計(jì)算，并對工作壓力、重播指數(shù)、漏播指數(shù)、粒距合格率等性能指標(biāo)進(jìn)行了臺架試驗(yàn)。試驗(yàn)結(jié)果表明，該排種器工作氣壓低、粒距合格率高，能夠適應(yīng)高速作業(yè)需求。

    Abstract:

    A mechanical-pneumatic combined corn precision seed-metering device was designed based on the structure of mechanical inside-filling seed-metering device and the single-seed reserving principle of the pneumatic seed-metering device. The basic structure and the working principle were expounded here. The critical components were designed based on the calculation. It’s performance such as working air pressure, seed overlap index, missing index and seed allocation eligible rates was investigated under laboratory. Experiment results indicated that this device had superior eligible rates of the seed individual spacing, low working air pressure and high speed adoptability.
