2.2.2. Roller Discs

The picking device is driven by the main drive shaft to rotate the drum disc to rotate the spring-finger shaft, thus completing the picking work. The size of the radius of the drum disc does not directly affect the spring-finger movement, but the size of the drum disc determines the size of the whole machine. Referring to agricultural machinery manuals and other similar picking devices in China, the final diameter of the drum is determined to be 320 mm. The structure of the drum is shown in Figure 6.
