Latest Patents

One of Nagamine's latest patents is the "Reversible Rotary Cultivating Apparatus." This invention features cultivating tines that have opposite cutting edge portions, which are pivotably supported by mount brackets on a tine shaft that can be reversibly rotated. The design allows one edge portion of each tine to be positioned rearward in the direction of forward rotation, while the other edge portion is positioned rearward in the direction of reverse rotation. The edge portions exhibit different upstanding postures when positioned for rotation in their intended direction. Notably, the curved edge line of the reverse-rotation edge portion is more upstanding than that of the forward-rotation edge portion when it contacts the ground.

Another significant patent is the "Device for Automatically Adjusting Tension of Endless Running Member." This device is designed for a wrapping connector driving apparatus used in agricultural machines. It includes a chain reeved around sprocket wheels on two shafts, with a tension adjusting device located on the slack side of the chain. A tightener applies pressure against the chain to maintain tension. The system features a piston that fits within an oil-enclosing cylinder, which is pressed against the tightener by a resilient member. This design allows the device to absorb abnormal loads acting on the chain, ensuring that the tension remains automatically adjustable.
