The invention relates to the related field of
coal mining, in particular to automatic sorting equipment which comprises a grading box, grading rollers, a driving
assembly, an adjusting
assembly, a conveying belt, an identifying
assembly and a collecting assembly.The automatic sorting equipment comprises the grading box, the grading rollers, a driving assembly, an adjusting assembly, a conveying belt, an identifying assembly and a collecting assembly.Firstly, raw
coal is poured into the grading box, and the size of a gap between every two adjacent grading rollers is adjusted through the adjusting assembly; raw
coal is graded one by one according to the size of the gaps between the grading rollers, then all the grading rollers are driven by the driving assembly to rotate, the raw coal which does not fall off from the gaps between the grading rollers moves in the length direction of the grading box, and the graded raw coal finally falls onto the conveying belt. According to the
coal gangue sorting device,
coal gangue in raw coal is recognized through the recognition assembly on the conveying belt, then the recognized
coal gangue is clamped through the material moving mechanism and moved out of the conveying belt, and the technical problems that when the coal
gangue is sorted in a manual mode, labor intensity is large, the
working environment is severe, and efficiency is low are solved.
