DESIGN AND EXPERIMENTAL STUDY ON FLUTE-WHEEL ONCENTRATE FEEDING MECHANISM FOR DAIRY COW

摘要

In order to carry out precision feeding for dairy cow, the authors developed a flute-wheel concentrate feeding mechanism which was controlled with ARM techniques. The structure and the operating principle of the flute-wheel concentrate feeding mechanism were introduced. By the experiments, some optimal parameters and the configuration of the parts were concluded, the brush with flush-sided end was fixed in the middle position, the working length of the flute-wheel with 16 flutes was 38 mm when the flute-wheel was used for discharging the small mass of the small pellet feed, while for discharging large mass of the large pellet feed, the working length of the flutewheel was 112 mm. The results also showed that the pellet level of the concentrate in the hopper did not have a significant influence on the full coefficient of the flute-wheel. It was confirmed that the average error of the discharging mass was less than 2%.
