three-wheel stirring mechanism 3d model

A mechanical stirring mechanism for a commercial wok cooking robot, NO lifting arm structure. Three wheels mounted on a circular track around the wok rim, wheels spaced 120 degrees apart. Three rigid connecting rods extending from the three wheels, converging at a center point directly above the wok. NO circular ring connecting the rods at the track level. The three rods are NOT connected to each other except at the center convergence point. Each rod independently connects one wheel to the center point. A screw linear actuator mounted at the convergence point, with a stirring blade attached vertically downward. One of the three wheels is a drive wheel with an integrated motor. The structure is open between the rods, with no obstructions. Polished stainless steel blade. Industrial design, mechanical engineering aesthetic. High detail, clean geometry. No background, no extra rings, no annular structures, no connecting circles.
