before the device is used, the adjusting bolt (24) on the outer cylinder (19) is firstly removed, so that the front end of the outer cylinder (19) is separated from the interior of the inner screw hole (25), then the upper half part of the outer cylinder (19) and the lower half part of the outer cylinder (19) are separated by separating the lock catch (23) on the fixing ring (22), the outer cylinder (19) is rotated by the hinge on the right side of the outer cylinder (19), so that the upper half part of the outer cylinder (19) is opened, a coal mine is loaded into the interior of the outer cylinder (19), then the outer cylinder (19) is closed according to the reverse steps, then the adjusting bolt (24) is installed into the corresponding inner screw hole (25) by rotating, so that the sizes of the crossed parts of the through hole (21) on the outer cylinder (19) and the through hole (21) on the annular inner plate (20) are adjusted, thereby adjusting the size of the screened coal mine; the device makes spring (3) stretched through lifting depression bar (4) on, and depression bar (4) slide in the inside of connecting sleeve (2), then anticlockwise rotates depression bar (4) 90 for depression bar (4) in connecting sleeve (2) break away from U type pole (7), thereby come to dismantle baffle (5) through cardboard (6), thereby take out the colliery that the inside screening was accomplished.
