    摘要:

    為獲得筑埂作業(yè)時(shí)土壤對(duì)其關(guān)鍵部件鎮(zhèn)壓筑埂裝置的作用力,以1DSZ-350型懸掛式水田單側(cè)旋耕鎮(zhèn)壓修筑埂機(jī)筑埂裝置為研究載體,采用應(yīng)變傳感器設(shè)計(jì)了鎮(zhèn)壓筑埂裝置動(dòng)力學(xué)參數(shù)測(cè)試系統(tǒng),并搭建動(dòng)力學(xué)測(cè)試試驗(yàn)臺(tái)。對(duì)鎮(zhèn)壓筑埂裝置的工作參數(shù)進(jìn)行測(cè)試,以鎮(zhèn)壓筑埂裝置前進(jìn)速度和轉(zhuǎn)速為試驗(yàn)因素,以田埂成型過(guò)程中土壤對(duì)彈性羽片作用力和田埂堅(jiān)實(shí)度為性能指標(biāo)進(jìn)行單因素試驗(yàn),獲得彈性羽片受土壤作用力、田埂堅(jiān)實(shí)度與鎮(zhèn)壓筑埂裝置前進(jìn)速度、轉(zhuǎn)速之間的關(guān)系。試驗(yàn)結(jié)果表明:當(dāng)鎮(zhèn)壓筑埂裝置轉(zhuǎn)速一定時(shí),隨著機(jī)具前進(jìn)速度的增加,土壤對(duì)彈性羽片作用力平均值增大,田埂堅(jiān)實(shí)度減小,變化范圍分別為:2838.1~5695.2N和2250~1680kPa;當(dāng)機(jī)具前進(jìn)速度一定時(shí),隨著鎮(zhèn)壓筑埂裝置轉(zhuǎn)速的增加,土壤對(duì)彈性羽片的作用力平均值與所筑田埂堅(jiān)實(shí)度均增大,變化范圍分別為:3203.8~5990.3N和1460~2180kPa。經(jīng)試驗(yàn)驗(yàn)證,工作參數(shù)測(cè)試系統(tǒng)的設(shè)計(jì)符合實(shí)際要求,為類似結(jié)構(gòu)裝置的相關(guān)參數(shù)測(cè)試提供了參考。

    Abstract:

    The object was to obtain the forces of soil on compacting ridge device of ridger when operating. Taking 1DSZ-350 type hanging unilateral rotary tillage compacting ridger for paddy field as research carrier, a kinetic parameters measurement system was designed for compacting ridge device using strain sensor, and a kinetic test bench was set up. The operation parameters of compacting ridge device were measured, and the variation rules of the force of soil on pinnae, and the relationships between ridge compaction and forward speed and rotation speed of compacting ridge device were obtained, which was carried out through single factor experiment with the forward speed and rotation speed of compacting ridge device as experiment factors, the force of soil on pinnae and the compaction of ridge in the process of building ridge as experiment indicators. The results showed that when the rotation speed of compacting ridge device was fixed , with the increase of forward speed of machinery, the average value of force of soil on pinnae was increased, and the compaction of ridge was decreased, which was in the range of 2838.1~5695.2N and 2250~1680kPa, respectively. When the forward speed of machinery was fixed, the average value of force of soil on pinnae and the compaction of ridge were increased with the increase of rotation speed of compacting ridge device, which was in the range of 3203.8~5990.3N and 1460~2180kPa, respectively. According to the test results, the test system for operation parameters of compacting ridge device can meet the requirements, which can provide important reference for the relevant parameters test of similar device.
