双螺旋式柑橘输送分级装置设计与试验
Design and experiment of double helix conveying and grading device for citrus
摘要
Abstract
To address the challenges of low efficiency in manual citrus grading,high costs,and the immobility of existing automatic citrus grading systems,a truck-mounted grading system based on a double screw conveyor was developed.Based on its overall structure and operational principles and considering the rotational characteristics of citrus fruits,the main factors influencing citrus rotational stability were identified as screw pitch,axis distance,bar height and rotational speed.The value range of key parameters for double screw mechanism was optimized by using SolidWorks Motion simulation.The response surface test was carried out by Box-Behnken center combination design,and the optimal parameter combination was obtained as follows:screw pitch 77.97 mm,axis distance 65.67 mm,bar height 36.35 mm,and rotational speed 161.83 r/min.Prototype test shows that for citrus fruits with diameters ranging from 60 to 100 mm,the system can achieve an average full surface acquisition rate of 96%under the optimal parameter combination,which meets the requirements for online citrus detection.The research provides a reference for the development of an truck-mounted online detection system for spherical fruits.关键词
