Design and experiment of grapevine cold-proof soil cleaner with combined scraping and brushing
Aiming at the problems of incomplete soil cleaning,easy damage to the grapevine and poor adaptation by mechanized soil cleaning in the open-field vineyards of northern China,a grapevine cold-proof soil cleaner with combined scraping and brushing is designed.The double-winged scraper components,rigid impeller components and flexible brush wire components are adopted,which can clean the cold-proof soil above the grapevine,the cold-proof soil on the side periphery and the cold-proof soil near the root of the grapevine at one time.The key components were design and a control system based on STM32F103 was built to realize automatic obstacle avoidance of scraper components and automatic leveling of the machine.Leveling performance tests showed that when the leveling frame was tilted to the left to the maximum angle or tilted to the right to the maximum angle,the automatic leveling process can be completed within 1 s,and there is no obvious overshooting.When the tractor was driven on uneven vineyards,the three soil cleaning components maintain the desired leveling angle at all times(within±2°),even if the tractor itself undergoes a large change in tilt.The field soil cleaning test showed that all the working components operated stably and there was no interference.After the soil cleaning operation,the soil cleaning rate was about 81.96％,and the grapevine damage rate was about 1.67％,which met the requirements of open-field grapevine cold-proof soil cleaning in northern China.
