| Abstract: | In order to solve the problem of air-suction cotton precision dibbler,which was steam leakage easily and the flow-performance was inferiors,an air-suction cotton precision dibbler was designed and tested in this paper.Its operating principle and structural feature were discussed and expounded.The key working parts were designed,the working process was analyzed.The tests indicated that this device can achieve the aim of precision metering,under the speed of 3.0 km/h,the single seed was more than 98.67%,the synthetically rate of seed was 95%,the multiples was 4.3%,the miss was 2.7%.The seed-metering device can satisfy the demand for precision seeding. |
