This paper designs an innovative cricket bowling machine that operates on the principles of catapult launching and spiral spring rebound recovery, aiming to provide a convenient cricket training experience for beginners. The device launches the cricket ball via a catapult mechanism, after the ball is hit, automatically retrieves it using a spiral spring to power a line wheel. During the launching process, a worm pair structure is employed to adjust the angle of the launch tube, accommodating diverse training needs. Meanwhile, precise coordination between a geared DC motor and a boss gear achieves precise control over the launching and retrieval processes. This paper comprehensively introduces the structural design, working principle, and programming of the device. The design is anticipated to stably launch and retrieve cricket balls, thereby significantly enhancing training efficiency and reducing the training burden on users. Furthermore, this paper analyzes the potential challenges of the device in practical applications and proposes improvement suggestions, providing valuable references for subsequent research.
