Design and experiment of disc cutting device for leek harvester
Aiming at the problems of incomplete and missing cutting in the existing leek harvester,combined with the physical characteristics of leek,a kind of leek collecting machine was designed.The structural parameters and motion parameters of the key components of the disc knife were determined,and the cutting theory was analyzed.By using MATLAB software,the motion simulation of the cutting disc was carried out when the working speed of the machine was selected as 0.2 m/s,0.3 m/s,0.4 m/s,0.5 m/s respectively,and the change law of cutting area under different operating speeds was obtained.Taking the working speed of the machines and tools as the test factor,and taking the header loss rate and missed cutting loss rate as the indicators,a single factor test was carried out.Through the analysis of the test results,the working speed range of the machines and tools was determined.The results showed that when the rotating speed of the disc cutter was 3 000 r/min and the working speed was 0.4 m/s,the performance of the leek cutting and harvesting device was the best,and the average loss rate of the leek cutting table was 2.8％and the average loss rate of the missing cutting was 2.2％.
