Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1

[0023] Please refer to Figures 1-5 As shown, the present invention provides an internal spray water distribution device for a roadheader, including a main shaft fixed seat 1. The inside of the main shaft fixed seat 1 is rotatably connected to a main shaft 2 through a bearing member. The front end of the main shaft 2 extends to the outside of the main shaft fixed seat 1. A water guide plate 3 is slidably connected to the surface of the main shaft 2, and a water sealing plate 4 is slidably connected to the surface of the main shaft 2 and in front of the water guide plate 3.

[0024] Specifically, a water guide groove 5 is formed on the surface of the main shaft 2, and a number of water guide grooves 5 are arranged in a ring shape. On one side of the inner cavity of the water guide disc 3 close to the main shaft 2, a water guide port 6 that cooperates with the water guide groove 5 is formed, and a number of water guide ports 6 are arranged in a ring shape. The rear part of the water guide disc 3 is communicated with a water inlet pipe 10. On the front side of the surface of the main shaft fixing seat 1, a threaded groove 12 is formed. A threaded sleeve 13 is threadedly connected to the surface of the threaded groove 12. An annular sliding groove 14 is formed on the surface of the threaded sleeve 13. An annular sliding bar 15 is slidably connected inside the annular sliding groove 14. A traction rod 16 is fixedly installed on the surface of the annular sliding bar 15, and a number of traction rods 16 are arranged in a ring shape. The front end of the traction rod 16 is fixedly installed with a pressing plate 17. The rear part of the pressing plate 17 is in close contact with the surface of the water sealing disc 4. A limiting plate 18 that cooperates with the pressing plate 17 is fixedly installed on the surface of the water sealing disc 4, and a number of limiting plates 18 are arranged in a ring shape. By providing the water guide disc 3, the water guide groove 5 and the water guide port 6, the water conveyed through the water inlet pipe 10 can enter the water guide disc 3 and finally flow out through the water guide port 6 and the water guide groove 5, achieving the effect of facilitating the conveyance of water. When maintenance is required, the threaded sleeve 13 can be rotated. When the threaded sleeve 13 rotates, it can move forward through the threaded groove 12. The movement of the threaded sleeve 13 drives the annular sliding bar 15 to move. The movement of the annular sliding bar 15 drives the traction rod 16 to move. The movement of the traction rod 16 drives the pressing plate 17 to move. After the pressing plate 17 moves, the water sealing disc 4 and the water guide disc 3 are no longer limited. At this time, the water guide disc 3 and the water sealing disc 4 can be pulled forward to achieve the effect of facilitating the removal and maintenance of the water guide disc 3 and the water sealing disc 4.

[0025] Specifically, a sealing gasket 11 is fixedly installed on the surface of the main shaft 2 and at the rear part of the water guide disc 3. An annular plate 7 is fixedly installed on the inner wall of the main shaft fixing seat 1 and at the rear part of the water guide disc 3. A limiting groove 8 is fixedly installed at the rear part of the water guide disc 3, and a number of limiting grooves 8 are arranged in a ring shape. The rear part of the limiting groove 8 penetrates through the annular plate 7 and extends to the outside of the annular plate 7. A limiting block 9 that cooperates with the limiting groove 8 is formed on the surface of the annular plate 7, and a number of limiting blocks 9 are arranged in a ring shape. By providing the annular plate 7, the limiting groove 8 and the limiting block 9, when the water guide disc 3 is inserted into the main shaft fixing seat 1, the water guide port 6 and the water guide groove 5 can be quickly aligned through the limiting groove 8 and the limiting block 9, thereby achieving the effect of improving the installation efficiency. At the same time, by providing the limiting plate 18, it can be ensured that after the pressing plate 17 is in close contact with the water sealing disc 4, the water sealing disc 4 will not rotate.

[0026] Working principle: The utility model is an internal spray water distribution device for a roadheader. By setting a water guide disc 3, a water guide groove 5 and a water guide port 6, the water conveyed through a water inlet pipe 10 can enter the water guide disc 3 and finally flow out through the water guide port 6 and the water guide groove 5, achieving the effect of facilitating water conveyance. When maintenance is required, the threaded sleeve 13 can be rotated. The rotation of the threaded sleeve 13 can move forward through a threaded groove 12. The movement of the threaded sleeve 13 drives the movement of an annular slide bar 15. The movement of the annular slide bar 15 drives the movement of a traction rod 16. The movement of the traction rod 16 drives the movement of a pressing plate 17. After the pressing plate 17 moves, the water sealing disc 4 and the water guide disc 3 are no longer limited. At this time, the water guide disc 3 and the water sealing disc 4 can be pulled forward to achieve the effect of facilitating the removal and maintenance of the water guide disc 3 and the water sealing disc 4. And by setting an annular plate 7, a limiting groove 8 and a limiting block 9, when the water guide disc 3 is inserted into the main shaft fixing seat 1, the water guide port 6 and the water guide groove 5 can be quickly aligned through the limiting groove 8 and the limiting block 9, thereby achieving the effect of improving the installation efficiency. At the same time, by setting a limiting plate 18, it can be achieved that after the pressing plate 17 tightly adheres to the water sealing disc 4, the situation of the water sealing disc 4 rotating is avoided.
