    摘要:

    為提高水田深施肥的施肥質(zhì)量，設(shè)計(jì)了一種葉片調(diào)節(jié)式水田側(cè)深施肥裝置,。應(yīng)用水田側(cè)深施肥肥量調(diào)節(jié)裝置計(jì)算機(jī)優(yōu)化軟件V1.0優(yōu)化求解施肥量調(diào)節(jié)機(jī)構(gòu)結(jié)構(gòu)參數(shù),，通過施肥量調(diào)節(jié)機(jī)構(gòu)受力分析,，確定步進(jìn)電動機(jī)的輸出扭矩應(yīng)大于680N·mm,。建立葉片調(diào)節(jié)式側(cè)深施肥裝置仿真模型,，應(yīng)用離散元EDEM軟件進(jìn)行排肥虛擬試驗(yàn),，分析螺旋鋼絲和毛刷在工作時受到肥料顆粒的作用力,，從而確定肥箱直流電動機(jī)和防堵裝置直流電動機(jī)的輸出扭矩應(yīng)分別大于5345N·mm和8N·mm,。通過JPS-12型排種性能檢測試驗(yàn)臺對槽輪式和葉片調(diào)節(jié)式水田側(cè)深施肥裝置進(jìn)行施肥性能研究，獲得了槽輪式水田側(cè)深施肥裝置的槽輪轉(zhuǎn)速和前進(jìn)速度對施肥穩(wěn)定性和均勻性影響規(guī)律,，以及葉片調(diào)節(jié)式水田側(cè)深施肥裝置的開口直徑和前進(jìn)速度對施肥穩(wěn)定性和均勻性影響規(guī)律,。對比試驗(yàn)結(jié)果表明：葉片調(diào)節(jié)式水田側(cè)深施肥裝置施肥穩(wěn)定性和施肥均勻性指標(biāo)滿足國家標(biāo)準(zhǔn)要求，在施肥質(zhì)量上優(yōu)于槽輪式水田側(cè)深施肥裝置,，施肥能力滿足農(nóng)藝要求,。

    Abstract:

    In order to improve the fertilization quality of deep fertilization for paddy field, an adjustable blades side deep fertilizing device for paddy field was designed. Structure parameters of fertilizer rate adjusting mechanism were optimized by using optimization software V1.0, which was developed for fertilizer rate adjusting mechanism of side deep fertilizing device for paddy field. The stress analysis was carried out for fertilizer rate adjusting mechanism, through which the output torque of stepper motor was determined greater than 680N·mm. Simulation model was established for adjustable blades side deep fertilizing device, and virtual experiment of distributing fertilizer was carried out by using discrete element EDEM software to analyze the acting force of fertilizer particle on spiral steel wire and hairbrush, therefore, the output torque of the direct current motor of fertilizer cases and anti-blocking device was determined greater than 5345N·mm and 8N·mm, respectively. Fertilization performance of groove wheel type and adjustable blade type side deep fertilizing device for paddy field were studied on JPS-12 type discharging seed performance detection test bench, through which the influence laws of the rotation speed and forward velocity of the groove wheel type side deep fertilizing device on fertilizer stability and uniformity were obtained, the influence laws of the opening diameter and the forward speed of adjustable blade type side deep fertilizing device for paddy field on fertilizer stability and uniformity were obtained. The test results showed that fertilizer stability and uniformity indexes of adjustable blade type side deep fertilizer device for paddy field can meet national standard requirements, the quality of fertilization was superior to that of groove wheel type side deep fertilizing device, and the fertilization ability can meet agronomic requirements.
