The present application relates to the technical field of animal husbandry, and particularly relates to a high-efficiency shearing device for sheep grass. The present application provides a high-efficiency shearing device for sheep grass, which can effectively avoid the phenomenon of sheep grass winding the device and effectively reduce the waste of sheep grass during the shearing process, thereby efficiently shearing the sheep grass. The present application comprises a vehicle body, a fork block and a moving mechanism, etc. The fork block is fixedly connected to one side of the lower part of the vehicle body, and the moving mechanism is arranged on the vehicle body. The transmission column is driven to rotate to drive the rotating column to rotate, thereby driving the plurality of cutting knives to reciprocatingly swing. The reciprocating swing of the cutting knives will continuously open and close with the fixed knives and cut the sheep grass between the fork blocks, thereby cutting the sheep grass, so as to collect the sheep grass. Meanwhile, the rotation of the winding shaft will wind the cut sheep grass, and the cut sheep grass is wound onto the conveyor belt. The rotation of the conveyor belt will convey the cut sheep grass to the vehicle body to collect the cut sheep grass, thereby completing the shearing of the sheep grass.

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.

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.

The invention discloses a primary rutile ore reverse flotation dephosphorization collecting agent methyl oleate sodium sulfonate (MOS), and belongs to the technical field of mineral flotation. The collecting agent MOS is a bifunctional anionic surfactant containing a sulfonic acid group and an ester group at the same time. In a reverse flotation system, MOS can be selectively adsorbed on a Ca < 2 + > active site on the surface of apatite and does not interact with a Ti < 4 + > site on the surface of rutile, so that the floatability difference of apatite and rutile is remarkably enlarged, and efficient separation of apatite and rutile is achieved. The collecting agent has the advantages of being simple in synthesis process, high in selectivity and the like, efficient dephosphorization of primary rutile ore can be effectively achieved, theoretical support and economic value are provided for clean utilization and sustainable development of titanium resources, and the application prospect is wide.
