Abstract

To address the environmental pollution caused by discarded non-biodegradable fruit bags in orchards, an air-suction orchard fruit-bag collection machine was developed. First, theoretical calculations and analyses were conducted on the key machine components to determine the main operating parameters. Kinematic analysis was then performed using ADAMS, and the airflow field was simulated using Fluent. Next, a prototype was manufactured. Based on multivariable response surface analysis conducted in Design-Expert, the optimal parameter combination was identified as a travel speed of 2 km/h, a suction-inlet air velocity of 15.5 m/s, and a helical-conveyor rotational speed of 66 r/min. Orchard field tests showed that, under the optimal operating conditions, the actual collection rate reached 82.5%, confirming that the machine met the intended design requirements.

针对果园废弃套袋纸不易降解、污染环境等问题，提出了气吸式果园套袋纸回收机的设计。首先对关键装置进行理论计算与分析，确定影响作业效果的关键因素，以此为基础进行ADAMS运动学分析和Fluent气流场仿真分析。然后进行样机研制，通过Design-Expert进行多因素响应面分析，确定整机的工作参数最佳组合为：行进速度为2 km/h、吸入口风速为15.5 m/s、螺旋输送装置转速为66 r/min。果园试验表明，在最佳工作参数下，样机试验回收率为82.5%, 验证本设计能够实现预期的工作效果。
