Design And Experiment Of Orienting Orderly Conveying Device For Garlic Root Disk Cutting

China is the main garlic producer,consumer and exporter in the world.In recent years,in order to enhance the overall economic benefits of garlic industry,garlic deep processing sector has been vigorously developed.Common garlic deep processing products need to be processed by multiple processes,including cutting root,cutting root disk,breaking,peeling,cleaning,drying and packaging.In the garlic root disk cutting process,the current commonly used garlic root disk cutting equipment is still feeding manually to realize directional and orderly feeding of garlic,which has high labor intensity and low work efficiency.At the same time,the orienting orderly feeding effect and adaptability of automatic garlic root disk cutting machine is poor and cannot satisfy the needs of efficient garlic root disk cutting.In order to save labor cost and improve the automation level of garlic root disk cutting,the automatic orienting transportation of garlic is urgently needed.Base on the above situation,this paper takes garlic with a diameter of 50 to 60 mm after cutting root disk as the research object,and aims to realize the orienting and orderly transportation of garlic.Referring to materials orienting technology in the areas of agricultural mechanization at home and abroad,a kind of garlic orienting orderly conveying device is proposed,hoping to achieve the full automation of garlic root disk cutting process.The main research contents of this paper are as follows:（1）Design of garlic orienting orderly conveying device.Taking the selected garlic as the research object,based on the analysis of the garlic shape characteristics,the overall scheme of garlic orienting orderly conveying device is proposed according to the attitude requirements of garlic in garlic root disk cutting process.（2）Research on simulation experiment of garlic feeding mechanism operation.The structure of garlic feeding mechanism is designed.The dynamic simulation model of garlic feeding mechanism is established by ADAMS.The simulation test is carried out and the attitude change of garlic in the feeding mechanism is analyzed to verify the rationality of feeding mechanism design scheme.The optimal structural parameters and operating parameters of the feeding mechanism were determined:When the pushing angle is 40°,the bias distance of the intervention bar is 60 mm and the pushing speed is100 mm·s^-1,the orienting success rate of garlic feeding mechanism simulation was88.9%,which provides parameters for the development of the test prototype.（3）Research on garlic attitude image recognition method.According to the inherent features of garlic,a garlic attitude recognition method based on garlic feature detection is proposed.The garlic feature detection classifier based on YOLOv5 model is built and trained,and the feasibility of the algorithm is verified by garlic attitude recognition experiment.The experimental results show that the success rate of garlic attitude recognition was 98.67%,and the correct rate of garlic deviation angle was97.33%.（4）Prototype construction and performance verification of garlic orienting orderly conveying device.The structure design,processing and assembly of garlic orienting orderly conveying device are completed.The hardware and software of the machine control system are designed and developed,and the prototype is also developed.The prototype performance verification test was performed,and it was determined that at the conveying speed of 95 mm·s^-1,the orienting success rate of garlic orienting orderly conveying device was 94.8%,and the conveying efficiency of the machine reached 73per minute.
