| 3. | Mechanization of rice - transplanting was a main measure to improve rice - transplanting efficiency and lessen the farmers " labor intensity 水稻插秧机械化是提高插秧效率、减轻农民劳动强度的主要措施之一。 |
| 4. | After the 1990 ' s , the transplanter in japan was researched and developed mostly aimed to reduce production cost , work force and to implement multiple functions 20世纪90年代后日本水稻插秧机主要向降低生产成本,节省劳动力以及多种功能方向开展研究与推广。 |
| 5. | Rotary - type transplanting mechanism of high - speed transplanter , with a transplant rate of 400 - 600 times per minute , represented the developing trend in the future 旋转式高速水稻插秧机的分插机构具有其自身优点,插次可达400 600次分钟,代表未来的发展趋势。 |
| 6. | However , the rate of rice - transplanting by machine was at a low level , only 2 . 8 percent in our country at present . it was mainly due to the low reliability of the rice transplanter produced in our country . moreover , the price of foreign high - speed rice transplanter was high and they could not fit the high rice seedlings of the autumn season in the south of china 如果我国插秧机械化水平提高1 ,每年就能增产粮食3 . 75亿kg ,但目前我国的机插率只有2 . 8 ,其主要原因是国产插秧机的可靠性低,而进口的高速插秧机价格太高且对我国南方双季稻的晚稻大苗栽插适应性差,因而研究适合我国国情的高速水稻插秧机势在必行。 |
| 7. | 1 ) the principles of various rotary - type transplanting mechanisms of high - speed rice transplanter had been studied , and the subjects for further research - - studying their dynamics characteristics to improve their dynamics performance and further to enhance the efficiency were put forward . an innovative idea of two - stage - optimization for dynamics analysis was presented in the paper . the creativity of the idea was that the kinematics optimization ( first stage optimization ) results were the constraint for dynamics optimization ( the second stage optimization ) 本文主要的研究内容和结果如下: 1 )研究国内外各种类型的旋转式高速水稻插秧机分插机构的工作原理,指出尚待研究的问题? ?研究其动力学特性,以改善动力学特性,进一步提高插次;为此提出了动力学两级优化的创新性思路? ?以运动学优化( 1级优化)得到的机构参数范围作为动力学优化( 2级优化)的约束条件,最终得到的最佳参数不仅能满足运动学的要求,又具有最佳的动力学特性。 |
| 8. | By study on rice direct planting machines existed , the baby rice seedling direct planting machine reformed from rice transplanting machine has a long term potential . it has unique and reasonable design both in eight separable boxes filled baby rice seedling and the sowing needles fixed on sowing wheel . but it still existed some problems of designs and manufactures , for example the machine could not going ahead because of the mud assembled on the boat board , the interference between the sowing needle and the check curtain etc . all this aff 对现有水稻直播种植机械的研究发现,水稻直播种植机械在原有的水稻插秧机的基础上改造具有较大的发展前景,采用的份隔式乳芽箱和拨苗轮的拨针的设计较为独特,也较为合理,但还存在某些设计和制造问题,如船板的淤泥现象,拨针和秧帘的干涉现象较为严重等,这些都严重影响了直播机的工作性能。 |
| 9. | Transplanting mechanism was the primary part of a transplanter . its performance would directly affect the efficiency and the quality of rice seedlings transplanting . therefore , the research in transplanting mechanism is worthy and significant for the development of high - spee d transplanter in our country 分插机构是水稻插秧机的核心工作部分,其工作性能直接影响插秧质量和效率,因此研究分插机构对最终研制出符合我国国情的高速水稻插秧机具有理论价值和重大现实意义。 |
| 10. | Funded by the national natural sciences foundation of china , prof . zhao yun of zhejiang university had invented 5 rotary - type transplanting mechanisms . all of them could meet the demands of locus and pose ( angle of seedling - separating and angle of seedling - pushing ) of rice - transplanting . but the dynamics characteristics of these mechanisms had not been further studied yet 浙江大学赵匀教授先后研究并发明了5种水稻插秧机的分插机构,它们都能满足各种水稻栽插的轨迹和姿态(取秧角和插秧角)的要求,但对这些机构的动力学特性未做进一步深入基础研究。 |
