[0048] The implementation principle of a sealed material guide trough in the present application is: the conveyor belt transports the coal, and during the conveying process, the rotating roller 22 arranged on the corrector 2 supports the conveyor belt, and the correcting roller 21 limits the conveyor belt to prevent the belt from deviating; the outer shell 1 is arranged above the corrector 2 and the conveyor belt, and the anti-overflow skirt 15 abuts against the conveyor belt to facilitate the sealing of the conveyor belt and prevent coal leakage; the column 13 supports the side guide plate 11 and the arc-shaped steel cover 12, and the dust suppression box 18 arranged on the top wall of the arc-shaped steel cover 12 reduces the impact force of the airflow carried by the coal in multiple stages through the curtain 181, so as to reduce the generation of coal dust.

[0049] When installing the overflow prevention skirt plate 15, first fit the overflow prevention skirt plate 15 with the outer side wall of the lining plate 14, then press the two side edges of the special-shaped angle aluminum 163 against the outer side wall of the overflow prevention skirt plate 15, so that the locking fixing rod 162 passes through the limit block 161, and the locking flange 1621 is close to one side of the lining plate 14, and the limit block 161 is close to the special-shaped angle aluminum 163, so that the convex edge of the special-shaped angle aluminum 163 is locked in the locking groove 1611 at one end of the limit block 161, and the other end of the limit block 161 is pressed against the outer side wall of the lining plate 14, and then the limit block 161 is moved, and the limit block 161 drives the locking fixing rod 162 to enter the sliding groove, and finally, the installation handle 164 is installed on the locking fixing rod 162, and the installation handle 164 is pressed.

During the transportation of coal, the anti-overflow skirt plate 15 is greatly worn. When the anti-overflow skirt plate 15 needs to be replaced, force is applied to the installation handle 164 to cause the installation handle 164 to rotate on the engaging fixing rod 162, and the engaging flange 1621 is moved away from the installation handle 164, so that the engaging flange 1621 is released from the pressing state against the sliding groove. Then, the installation handle 164 is moved to cause the engaging flange 1621 to disengage from the sliding groove, so that the special-shaped angle aluminum 163 and the anti-overflow skirt plate 15 fall off, thereby realizing the removal of the anti-overflow skirt plate 15.
