The circular arc groove 7 is blocked by the circular arc plate 4 sliding on the slide rails 21, preventing the ore material in the tee housing 1 from leaking out of the circular arc groove 7 and injuring people, thereby ensuring the safe operation of the operator.

[0028] The slide rail 21 includes an annular circumferential plate 9 and an annular retaining ring 10. The annular circumferential plate 9 is arranged on the outer peripheral side of the circular arc groove 7. The annular circumferential plate 9 is perpendicular to the side of the tee shell 1. The annular circumferential plate 9 is welded to the side of the tee shell 1. The end of the annular circumferential plate 9 away from the circular arc groove 7 is welded and fixed to the annular retaining ring 10. The annular retaining ring 10 has an annular notch 12. The side of the tee shell 1, the annular circumferential plate 9 and the annular retaining ring 10 form a track space 11. The circular arc plate 4 slides in the track space 11.

The telescopic push rod 16 is movably connected to the electro-hydraulic drive device 15.

[0033] The operating principle of the three-way material distribution structure: the electro-hydraulic drive device 15 drives the end of the telescopic push rod 16 to move. When the telescopic push rod 16 drives the flap 2 to rotate to the appropriate position, the telescopic push rod 16 is fixed, and the flap 2 adjusts the discharge amount of the two discharge ports 6. The telescopic push rod 16 simultaneously drives the arc plate 4 to move along the slide rail 21. No matter which position the arc plate 4 moves to, it can block the arc groove 7.
