摩擦型立式圆盘精密排种器的设计与试验
Design and experiment of friction vertical plate precision seed-metering device
摘要
Abstract
In order to solve the problems of low dropping limit velocity and small filling power, a new type of friction plate precision seed-metering device was devised, and the force and movement mechanism of seeds were analyzed in the course of filling seeds space. The seeds were driven to flow by the friction on the friction plate, and the filling power increased as well as the efficiency was improved. The new device was tested on test bench and the result indicated that when the plant spacing was 10cm, seedbed belt speed was 10.1 km/h, the limited speed of seed plate reached to 0.66m/s, and the qualification index was higher than 95%, overlapping seeding index was lower than 5% and missing seeding index was lower than 5%. It is shown that the seed meter is suitable for high-speed and accurate sowing.关键词
