仿生鼹鼠前肢自适应清秸装置设计与试验
Design and Experiment of Bionic Mole Forelimb Adaptive Stubble Removal Device
摘要
Abstract
Due to the adoption of no-till sowing technology,which results in thick and abundant corn stalks,traditional stalk cleaning mechanisms lack sufficient throwing force and exhibit unstable operating depths,severely constraining seeding quality.A bionic mole forelimb adaptive stubble removal device was designed,which can effectively remove stubble under full straw mulch.The stalk cleaning device consisted of a bionic stalk cleaning mechanism and an adaptive cleaning control system.The operational mechanism of the bionic stalk cleaning device,incorporating the movement morphology and law structure inspired by mole forelimbs,was investigated through theoretical analysis and computer simulation,aiming to elucidate the influence of structural parameters n the quality of cleaning.A fuzzy control algorithm was used to design the adaptive cleaning control system,enhancing the stability of the cleaning device's operating depth.The structure design and parameters of bionic straw removal mechanism were optimized by EDEM simulation software,and the type of bionic straw removal mechanism was determined.The regression equation between different parameters of the bionic straw removal mechanism and the evaluation index was established by Design-Expert software,and the optimal parameter combination was determined:the rotation radius was 150 mm,the bionic angle was 17.71°,the straw cleaning rate was 92.30％,and the working resistance was 30.38 N.Field experiments were conducted to verify the operational performance of the bionic mole forelimb stalk cleaning mechanism and the adaptive cleaning control system,comparing them with a conventional flat stalk cleaning mechanism.The experimental results demonstrated that the performance of the bionic stalk cleaning mechanism exceeded that of the conventional flat stalk cleaning mechanism,and the adaptive cleaning control system effectively improved the performance of the cleaning mechanism.When operating in fields with full straw coverage,the clearance rate of the bionic mole forelimb-adaptive stalk cleaning device reached 90.9％,which was 21.3 percentage points higher than that of the conventional stalk cleaning mechanism,meeting the agricultural requirements for no-tillage corn seeding after operation.关键词
