Randomized trial evaluates mechanical jujube picker performance in Xinjiang orchards, indicating high efficiency and reliability.

The aim is to design a mechanical jujube picker that efficiently collects jujubes from the ground while minimizing damage.
Designed a mechanical floor-standing jujube picker based on the characteristics of Xinjiang jujube orchards.
Conducted a Box–Behnken test analyzing multiple factors affecting jujube collection efficiency and damage.
Evaluated performance indicators such as pickup, breakage, and impurity rates during trials.
Achieved a jujube pickup rate of 92.11% with a forward speed of 0.3 m·s−1 and optimal machine settings.
Observed a breakage rate of 2.07% and an impurity rate of 4.15% during operation.
Model predictions had a relative error of less than 8%, confirming reliability.
