Motor 301 drives the drive rod 302 to rotate, which in turn drives the ring frame 104, which is fixedly connected to the drive rod 302, to rotate. The rotation of the ring frame 104 drives the third gear 309, which is rotatably connected to it, to perform circular motion within the gear ring 105. This causes the connecting assembly 310, which is rotatably connected to the third gear 309, to perform circular motion, carrying the rust-removing cylinder 4, which is fixedly connected to the connecting assembly 310, to perform reciprocating motion within the hydraulic cylinder of the coal mining machine. At the same time, the rotation of the drive rod 302 drives the first bevel gear 303, which is fixedly connected to it, to rotate. The second bevel gear 304, which is meshed with the first bevel gear 303, begins to rotate. The rotation of the second bevel gear 304 drives... The rotating rod 305, which is fixedly connected to it, rotates. The rotation of the rotating rod 305 drives the synchronous belt 306, which is connected to the synchronous belt 306, to rotate the telescopic outer rod 307, which is connected to it. The rotation of the telescopic outer rod 307 drives the telescopic inner rod 308, which is engaged with it, to rotate. This causes the rust removal brush 402, which meshes with the telescopic inner rod 308, to rotate. The rotation of the rust removal brush 402 drives the cylinder 401, which is fixedly connected to it, to rotate. The rust removal mechanism 3 allows the cylinder 401 to rotate while it is extending and retracting for cleaning, which can clean the dead corners of the hydraulic cylinder of the coal mining machine and can efficiently and comprehensively remove rust from the hydraulic cylinder of the coal mining machine.

[0020] The working principle of this utility model: First: Start the hydraulic rod 202. The mounting component 1, which is fixedly connected to the hydraulic rod 202, rises smoothly. The rust removal mechanism 3, which is fixedly connected to the mounting component 1, rises accordingly, thereby raising the rust removal cylinder 4, which is fixedly connected to the rust removal mechanism 3. This allows the height of the coal mining machine hydraulic cylinder rust removal device to be adjusted, enhancing its adaptability and improving rust removal efficiency.

[0021] Secondly: The starting motor 301 drives the drive rod 302 to rotate, which in turn drives the ring frame 104 fixedly connected to the drive rod 302 to rotate. The rotation of the ring frame 104 drives the third gear 309, which is rotatably connected to it, to make a circular motion in the gear ring 105. This causes the connecting component 310, which is rotatably connected to the third gear 309, to make a circular motion, which in turn causes the rust removal cylinder 4, which is fixedly connected to the connecting component 310, to make a reciprocating motion in the cylinder of the coal mining machine hydraulic cylinder. Finally: At the same time, the rotation of the active rod 302 will drive the first bevel gear 303 fixedly connected to it to rotate. The second bevel gear 304, which is meshed with the first bevel gear 303, will start to rotate. The rotation of the second bevel gear 304 will drive the rotating rod 305 fixedly connected to it to rotate. The rotation of the rotating rod 305 will drive the synchronous belt 306 connected to the rotating rod 305 to drive. The synchronous belt 306 will drive the telescopic outer rod 307 connected to it to rotate. The rotation of the telescopic outer rod 307 will drive the telescopic inner rod 308 that is engaged with it to rotate. This will cause the rust removal brush 402 that is meshed with the telescopic inner rod 308 to rotate. The rotation of the rust removal brush 402 will drive the cylinder 401 fixedly connected to it to rotate. The rust removal mechanism 3 is set so that the cylinder 401 can rotate while it is telescopically cleaning, which can clean the dead corners of the hydraulic cylinder of the coal mining machine and can efficiently and comprehensively remove rust from the hydraulic cylinder of the coal mining machine.
