2. The Anatomy of Precision: How Our Feed Gearbox Operates<\/h2>\n

The longitudinal feed case sits at the rear of the rice transplanter chassis, connected directly to the primary power take-off (PTO) chain or shaft. Its role is to translate continuous rotational power into a stepped linear motion for the seedling tray. Inside the housing, a high-precision **Globoidal Cam** or **Cylindrical Cam** system interacts with follower rollers. As the input shaft turns, the cam’s profile dictates the exact moment the tray moves sideways, coinciding with the exact moment the planting fingers are in the “reset” position.<\/p>\n
