چکیده
A seedling picking device is an essential component for automatic transplanter to automatically convey the dibbling part. It necessary find appropriate material and dimensions gears avoid mechanical damage increase their durability. Therefore, objectives of this research were analyze stress a gear mechanism in order select suitable materials dimensions, predict fatigue life by considering level. The shaft divided input power into two categories, i.e., crank cam sets. Finite element analysis simulation American Gear Manufacturers Association standard theory tests conducted on both sets different dimensions. test bench was fabricated collect load (torque) data at operating speeds. torque analyzed using duration distribution method observe cyclic patterns. Palmgren–Miner cumulative rule used determine level with respect speed. desired lifespan 255 h meet real field service requirement. Predicted range recorded as from 436.65 4635.97 h, making it higher (by approximately 2 18 times) than transplanter. According analyses, “Steel Composite Material 420H carbon steel” 5 mm face width operate 10-year life. presented study will guide design effective properties maintain recommended pepper

At present, the fruit picking in most countries still largely relies on manual operation. Manual fruit picking can protect the fruits from damage during the operation process. However, it is time-consuming and labor-intensive, and poses a potential safety risk to the workers while working at heights not reachable. Therefore, a variety of fruit picking machines and platforms have been developed ...
