AI Technical Summary
Traditional tobacco curing barns have simple lifting devices with limited functionality, which leads to high risks, high labor intensity, and poor equipment adaptability for tobacco farmers when handling and retrieving tobacco, making it impossible to meet both the needs of handling and retrieving tobacco.
A multifunctional liftable support was designed, which uses a servo motor to drive the winding shaft to achieve automatic lifting of the steel plate platform. Combined with the locking mechanism of the slide and the slot, it is equipped with a high-temperature resistant silicone tray and guardrail. The worm gear transmission system provides a self-locking function to ensure the stability and safety of the platform.
It significantly reduces the labor intensity of manual handling, avoids the safety hazards of traditional ladder operations, improves the efficiency and safety of tobacco curing operations, and realizes the integrated operation of tobacco stalk handling and post-curing tobacco leaf removal, making it suitable for the agricultural mechanization upgrade of small and medium-sized curing barns.
