Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-2 The utility model provides an interconnected coal drop pipe for a coal crusher room, including a drop port 1 and a drop port 2 for receiving materials falling in, and also includes an interconnected chute 3 and two special-shaped chutes 4. The upper ends of the two special-shaped chutes 4 are respectively connected to the drop port a 1 and the drop port b 2. The drop port a 1 and the drop port b 2 are both funnel-shaped, and their lower ends are connected to the upper ends of the special-shaped chutes 4 by a clamp connection. The interconnected chute 3 is in an "X" shape, and the two pipe openings at the upper and lower ends of the interconnected chute 3 are respectively connected to the upper and lower ends of the special-shaped chute 4 at the corresponding positions. A first reversing valve 7 is installed at the connection between the special-shaped chute 4 and the interconnected chute 3. The first reversing valve 7 is used to open or close Close the two pipe openings at the upper end of the interconnecting chute 3 and the passage of the special-shaped chute 4. When the first reversing valve 7 closes the pipe opening at the upper end of the interconnecting chute 3, the material can directly fall from the a dropout port 1 and the b dropout port 2 into the special-shaped chute 4 directly below it. When the first reversing valve 7 closes the upper end of the special-shaped chute 3, the material falls from the a dropout port 1 and the b dropout port 2 into the interconnecting chute 3, so that the material can fall into the special-shaped chute 4 at the opposite position. A second reversing valve 8 is installed at the intersection of the two pipe openings at the lower end of the interconnecting chute 3. The second reversing valve 8 is used to open or close the passage of the two pipe openings at the lower end of the interconnecting chute 3. The second reversing valve 8 can switch the closing and opening of the two pipe openings at the lower end of the interconnecting chute 3.

[0019] Furthermore, in this embodiment, in order to facilitate the collection of materials falling from the special-shaped chute 4, the lower end of the special-shaped chute 4 is connected to a collection bin 5, a discharge port is provided at the bottom of the collection bin 5, and a conveyor belt 10 is provided below the collection bin 5.

[0020] In order to control the timing of the material falling onto the conveyor belt 10 , in this embodiment, a double-opening valve 6 is installed inside the collecting bin 5 near the discharge port.

[0021] In this embodiment, the first reversing valve 7 and the second reversing valve 8 are both single-disc valves, and the double-opening valve 6 is a double-disc valve.

[0022] In this embodiment, the upper portion of the special-shaped chute 4 is inclined toward the interconnecting chute 3 , thereby reducing the material flow rate and the impact force of the material, thereby avoiding the risk of breakage at the connection of the special-shaped chute 4 .

[0023] Furthermore, in order to improve the sealing performance of the gate of the first reversing valve 7 closing the special-shaped slide pipe 4, in this embodiment, a stop bar is fixedly installed at the upper end of the inner wall of the special-shaped slide pipe 4 away from the interconnecting slide pipe 3, and a sealing rubber is fixedly installed on the upper part of the stop bar. When the first reversing valve 7 closes the special-shaped slide pipe 4, the gate of the first reversing valve 7 fits with the sealing rubber.
