This application relates to the field of kudzu harvester technology, specifically disclosing a method and system for adaptive adjustment of the soil entry angle of a vibratory shovel in a kudzu harvester. The method includes collecting intrinsic soil data and initial soil entry angle of the current working area; determining soil characteristic parameters, target vibration parameters, and target reference resistance corresponding to the intrinsic soil data based on a preset soil frequency resistance mapping table; inputting the soil characteristic parameters, target vibration parameters, and target reference resistance into a preset angle dynamic correction model, and outputting the target soil entry angle of the vibratory shovel; adjusting the angle of the vibratory shovel according to the difference between the target soil entry angle and the initial soil entry angle; and collecting the actual soil entry angle of the vibratory shovel in real time during the adjustment process, and dynamically correcting the adjustment deviation by combining a proportional-integral-differential error correction algorithm to adaptively adjust the soil entry angle of the vibratory shovel. The method achieves the high-efficiency and low-consumption operation requirements of the harvester by adaptively adjusting the soil entry angle for soils of different hardness.

This application provides a method for flotation separation of chalcopyrite and pyrite, relating to the field of mineral flotation. The method involves mixing and flotation of the minerals to be processed, including chalcopyrite and pyrite, with a chalcopyrite collector to obtain chalcopyrite concentrate and pyrite tailings. The general structural formula of the chalcopyrite collector is: [Formula omitted]. This chalcopyrite collector utilizes the high selective affinity of its propyne ester group for copper-active sites on the chalcopyrite surface and its inertness to iron sites on the pyrite surface, achieving precise identification and collection of chalcopyrite from the molecular structure of the reagent, significantly improving the grade and recovery rate of the copper concentrate. The R group is a hydrophobic group facing the pulp, significantly enhancing the surface hydrophobicity of the chalcopyrite particles, thereby enabling them to adhere to flotation bubbles and float.
