step two: after the material taking rod (65) moves to the surface of the coal pile, the second rotating motor (69) drives the third screw rod (691) to rotate, at the moment, the material taking head (695) rotates to move to one side through the third screw rod (691), the material taking rod (65) moves downwards while moving, so that a layer of coal on the surface of the coal can be peeled off, then the spiral rod (66) rotates under the driving of the first rotating motor (67), and the peeled coal is rotated to the inside of the material taking rod (65);
step three: then filling coal into the material taking rod (65), enabling the material taking rod (65) to move upwards under the rotation of the second screw rod (64), enabling the mounting piece (61) to move towards the position where the material receiving mechanism (7) is arranged on one side, enabling the first rotating motor (67) to rotate in the reverse direction after the material taking rod (65) moves upwards to the position above the material receiving hopper (71), and enabling the coal collected in the material taking rod (65) to be put into the material receiving hopper (71) in a rotating mode;
step three: meanwhile, in the process that the material taking rod (65) moves upwards, the outer surface of the material taking rod (65) can be cleaned by brushing through the arranged annular cleaning plate (698), so that the cleanliness of the outer surface of the material taking rod (65) is improved, and the material taking rod (65) is prevented from being damaged due to more and more attached coal ash;
step four: then, after the sample coal is put into the receiving hopper (71), the sample coal falls onto the filter plate (72), the swinging motor (74) is electrified to operate through electrifying the swinging motor (74), and then the filter plate (72) swings left and right, so that the coal sample falling to the surface can be filtered and sieved;
step five: the coal ash falling during sieving falls into a containing box (76) arranged at the lower end of the cavity (75), and after long-time use, the containing box (76) is taken out and cleaned through a recovery opening (77) formed in one side of the material conveying frame (2) so as to be convenient for next use;
step six: the sieved sample coal is inclined towards one side by the filter plate (72) through the swing motor (74), so that the sample coal is poured onto the conveyor belt (78), and the conveyor belt (78) rotates through the electric roller (79) to convey the sample coal to the detection table equipment for detection and evaluation.
