Two-stage harvesting is the main method for performing mechanized of peanuts, and picking device a core part combined harvester in China. In order to solve problem pod loss caused by "stacking", "impact" "throwing up" peanut plants traditional cam-slide spring-finger cylinder device, shovel-finger peanut-picking was developed used picking-up performance test based on study peanut-plant strip-pi...

In this paper, the blasting parameters are designed based on drilling data of exploration geological stage, geophysical and mechanical mining area, age information, numerical simulation layered rock steps is carried out to optimize parameters. Multiple sets tests were on-site, large block rate, average size satisfaction cost shovel loading efficiency, effect rate set as evaluation indicators, w...
