根据目前水稻育秧设备发展现状,以及农民使用需求情况,研制了工作效率为1 000盘h的水稻精量播种机,该机可一次性完成铺底土、淋水、播种和覆表土作业。介绍了其基本机构、工作原理,以及各组成部件的设计,并进行了试验。试验结果表明:该机工作效率高,作业质量好,播种效果完全达到了农艺要求,为提高水稻生产机械化作业技术水平创造了条件。
According to the current development status of rice seedling raising equipment and the needs of peasants, a rice precision sowing machine with a working efficiency of 1 000 disk h was developed. The machine can finish subsoil, watering, sowing and topsoil operation at one time. The basic structure, working principle and the design of each component are introduced and tested. The test results show that the machine has high working efficiency and good operation quality, and the sowing effect fully meets the requirements of agronomy, which has created conditions for improving the technical level of mechanization of rice production.
