[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4As shown, an auxiliary cooling device for a rocker arm of a coal mining machine comprises a rocker arm body 1, guide assemblies 2 are installed on both sides of the rocker arm body 1, the guide assemblies 2 include three guide pipes 4, three pipe grooves 5 are opened on both sides of the rocker arm body 1, the three guide pipes 4 are respectively located in the three pipe grooves 5, a flow groove 6 is arranged inside the guide pipe 4, a plurality of baffles 7 are movably installed inside the flow groove 6, a rotating shaft 8 is installed between the top of the baffle 7 and the top inner wall of the flow groove 6, and a block 9 is installed on the bottom inner wall of the flow groove 6 and below each baffle 7.

[0023] In this embodiment, three guide tubes 4 are arranged side by side. The guide tubes 4 are located in the tube groove 5 and are clamped. The guide tubes 4 are in contact with the outer shell 1 of the rocker arm body to cool the internal gear cavity of the rocker arm body 1.

[0024] In this embodiment, the baffle 7 is located inside the circulation groove 6 and is inclined. The baffle 7 is located inside the circulation groove 6 and is rotatable via the rotating shaft 8. The coolant is transported to the guide tube 4 for cooling, and the coolant flows through the rotation of the baffle 7.

[0025] In this embodiment, the side view of the block 9 is triangular, and the top of the block 9 matches the bottom of the baffle 7. The baffle 7 is pushed to rotate during the flow of the coolant, and the baffle 7 automatically closes the flow slot 6 when the coolant flows back.

[0026] In this embodiment, a heat dissipation assembly 3 is installed on the outside of the guide tube 4. The heat dissipation assembly 3 includes a plurality of fins 10. The plurality of fins 10 are welded on the outside of the three guide tubes 4. A plurality of nozzles 11 are installed on the outside of the middle guide tube 4. The fins 10 increase the heat absorption area and range of the outer shell of the rocker arm body 1, thereby further enhancing the heat dissipation of the rocker arm body 1.

[0027] In this embodiment, a plurality of fins 10 are installed vertically and equidistantly outside the guide tube 4 . The fins 10 pass through the outside of the rocker arm body 1 . The heat of the rocker arm body 1 is absorbed by the fins 10 and cooled by the coolant in the guide tube 4 .

[0028] In this embodiment, a plurality of nozzles 11 are arranged at equal intervals, and the nozzles 11 are communicated with the interior of the middle flow guide tube 4, and part of the coolant is sprayed out through the nozzles 11 in atomized form to reduce the diffusion of dust.
