Description

<p>A fertilizer application unit with a working speed-interlocking system for a riding-type tea field management machine was developed. The working speed-interlocking mechanism varies the number of rotations of the screw feeder in accordance with the working speed. The amount of discharge was found to be proportional to the rotation of the screw feeder. The speed-interlocking device could spread the fertilizer evenly in the field under a wide range of working speeds. The experimental results of the field test showed that the calculated field capacity using the prototype was 0.80-1.13 ha/h, and the effective field capacity was 0.24-0.29 ha/h. The actual application amount was 89-109% of the target application amount.</p>
