鲜食玉米对辊旋转分离摘穗和输送装置的设计与试验
Design and Experiment of Fresh Corn on Roller Rotating Seperation Snapping and Conveying Device
摘要
Abstract
Aiming at the problem of high ear damage rate and stem breaking rate in the process of picking and conveying of fresh corn combine harvester,the picking device and conveying device of fresh corn were designed.Combined with theoretical analysis and actual operating conditions,the structural design of the snapping device,conveying device and cutter device was completed,and the key operating parameters such as the speed of the snapping roller and the speed of the clamping mechanism were determined.According to the operation of the whole device and the actual operation require-ments,the hydraulic system of the device was designed to ensure the realization of the function of the fresh corn harvester.The designed ear picking and conveying device was installed on the main machine of 4YX-4 fresh corn stalk-ear combine harvester for field experiment.The clamping belt speed(1.5-2.3 m/s),the rotation speed of ear picking roller(280-800 r/min)and the forward speed(0.56-1.67 m/s),which had great influence on the ear damage rate and stem breaking rate,were selected as the experimental factors.The ear damage rate and stem breaking rate were used as the ex-perimental indexes to carry out the three-factor and five-level central repeated test.The ear damage rate ranged from 0.21%to 1.10%,and the stem breaking rate ranged from 0.32%to 0.64%.The test results were analyzed by variance analysis,and the significant effects of various factors and interactions on the test indicators were obtained.Design-Expert 6.0.10 software was used for optimization analysis,and the optimal combination parameters were 395 r/min of picking roller speed,1.7 m/s of clamping belt speed and 0.84 m/s of forward speed.The optimal combination parameters were verified,and the average ear damage rate was 0.24%and the stem breaking rate was 0.40%.All the test results were within the standard range and met the agronomic requirements of fresh corn harvest.关键词
