Structural Design and Gear Simulation Analysis of the Feeding Device of a Round Baler
Abstract：To solve the problems of feeding blockage and low baling efficiency in balers, the structural design of the feeding device of a round baler was carried out. The feeding device mainly consists of a feeding frame, double-row sprocket, feeding rotor, a pair of gears, output shaft, and grass removal mechanism. The feeding rotor adopts a four-star dual-picking tooth structure, which can evenly convey straw. The gear pair smoothly transmits power, effectively reducing feeding blockage and impact from alternating loads on the round baler. Based on theoretical formulas, the feeding capacity, output shaft, and force parameters of the gear pair were calculated to verify the rationality of the feeding mechanism design. ANSYS finite element analysis software was used to perform a transient dynamic analysis of spur gear meshing, to evaluate its dynamic performance, providing an effective reference for subsequent prototype testing.
