The bottom of the cooling box component 501 is fixedly connected to a first circulation pipe 502. A water pump 503 is fixedly installed on the outer side of the first circulation pipe 502.

The back of the intermediate circulation ring 504 is fixedly connected to a cooling cutting edge assembly 505.

[0025] In a preferred embodiment, the cooling box assembly 501 includes a cooling box body 5011. A front mounting frame 5012 is fixedly connected to the front surface of the cooling box body 5011. Fixing grooves are provided on both sides of the front surface of the front mounting frame 5012. A fan support frame 5013 is fixedly connected to the inner side of the fixing groove of the front mounting frame 5012. A cooling fan blade 5015 is movably installed at the center of the fan support frame 5013. A braking motor 5014 is fixedly installed on the front surface of the cooling fan blade 5015. By the mutual cooperation of the cooling box assembly 501 and the cooling blade assembly 505, the cooling efficiency is further improved.

[0026] In a preferred embodiment, two second circulation pipes 5053 are fixedly connected to both sides of the bottom of the back surface of the intermediate circulation ring 504. A cutting edge cooling pipe 5051 is fixedly connected to the bottom of the side of the second circulation pipe 5053 away from the intermediate circulation ring 504. A relief area cooling pipe 5052 is fixedly connected between the two cutting edge cooling pipes 5051.

[0027] In a preferred embodiment, heat dissipation slots are provided on both sides of the cooling box body 5011. The depth of the heat dissipation slot of the cooling box body 5011 is fifteen millimeters greater than the distance from one side of the cooling box body 5011 to the center of the braking motor 5014. When the cooling liquid moves into the cooling box body 5011, the shape of the heat dissipation holes of the cooling box body 5011 makes the heat dissipation area larger. At this time, the braking motor 5014 is started to drive the cooling fan blade 5015 to rotate. The wind generated by the cooling fan blade 5015 blows through both sides of the cooling box body 5011, and cooperates with the heat dissipation holes of the cooling box body 5011 to accelerate the liquid cooling speed.

[0028] In a preferred embodiment, the cutting edge assembly 3 includes a cutting edge main body 301. A cooling pipe placement groove 302 is provided inside the cutting edge main body 301. Wedge cutting edges are fixedly connected to both sides of the bottom of the cutting edge main body 301. A relief groove is provided in the middle of the cutting edge main body 301.

[0029] In a preferred embodiment, the cutting edge cooling pipe 5051 and the relief area cooling pipe 5052 are located in the cooling pipe placement groove 302. The relief area cooling pipe 5052 is located at the top of the relief groove of the cutting edge main body 301. The cutting edge cooling pipe 5051 is located at the top of the wedge cutting edge of the cutting edge main body 301. By providing the cooling assembly 5, when the cutting edge main body 301 overheats during the cutting process, the cooling liquid circulates in the cooling blade assembly 505 located in the cooling pipe placement groove 302 to dissipate heat from the cutting edge main body 301, reduce the heat accumulation during its cutting operation, and improve its service life.

[0030] Working principle of the present utility model: When the cutting edge body 301 overheats during the cutting process, the cooling liquid flows through the cooling blade assembly 505 located in the cooling pipe placement groove 302 to dissipate heat from the cutting edge body 301. If the temperature rises when flowing through the cooling blade assembly 505, the liquid flows back and forth between the cooling box assembly 501 and the cooling blade assembly 505 driven by the first flow pipe 502. When the cooling liquid moves to the cooling box body 5011, the shape of the heat dissipation holes in the cooling box body 5011 results in a larger heat dissipation area. At this time, the braking motor 5014 is started to drive the cooling fan blade 5015 to rotate, and the wind generated by the cooling fan blade 5015 blows through both sides of the cooling box body 5011, cooperating with the heat dissipation holes in the cooling box body 5011 to accelerate the cooling speed of the liquid. The cooling liquid then flows back to the cooling blade assembly 505 to continue dissipating heat from the cutting edge body 301.
