The gasket 104 is arranged on one side of the cover body 102, and the gasket 104 is embedded in the first embedding groove 105. The outer wall of the sealing ring 103 has a plurality of waterproof embedding grooves 106, and the plurality of waterproof embedding grooves 106 are evenly arranged on the outer wall of the sealing ring 103. The gasket 104 is embedded in the first embedding groove 105. 05, and embed the sealing ring 103 into the interior of the clutch main housing 101 until the gasket 104 contacts the clutch main housing 101, and the clutch main housing 101 and the cover body 102 are closed, and the cover body 102 and the clutch main housing 101 are sealed by the gasket 104, and at the same time, the sealing ring 103 and the clutch main housing 101 can be sealed through the multiple waterproof grooves 106, so as to improve the water sealing performance. At the same time, it does not affect the normal operation of the clutch, and can effectively water-seal the clutch, and improve the sealing performance through multiple groups of combined waterproof structures.

[0023] Secondly, there are multiple groups of the first sealing rings 107, which are respectively embedded in the corresponding waterproof grooves 106. One side of each group of the first sealing rings 107 is provided with a sealing lip 108, which is used for water sealing.

[0024] At the same time, there are multiple groups of second sealing rings 109, which are respectively embedded in the corresponding waterproof embedding grooves 106. One side of each group of second sealing rings 109 has a U-shaped groove 110, and each group of second sealing rings 109 is alternately arranged with each group of first sealing rings 107. Water sealing is performed through the U-shaped grooves 110. The U-shaped grooves 110 fill and seal the gap between the sealing ring 103 and the clutch main housing 101, making it difficult for water to penetrate, thereby achieving a water-sealing effect.

[0025] When using a tractor clutch housing of the present embodiment, the gasket 104 is embedded in the first embedding groove 105, and the sealing ring 103 is embedded in the clutch main housing 101 until the gasket 104 contacts the clutch main housing 101, the clutch main housing 101 and the cover body 102 are closed, the gasket 104 seals the cover body 102 and the clutch main housing 101, and the sealing ring 103 and the clutch main housing 101 are sealed by the plurality of waterproof embedding grooves 106, so as to improve the water sealing performance, and at the same time, the normal operation of the clutch is not affected, and the clutch can be effectively water-sealed, and the sealing performance is improved by a plurality of combined waterproof structures, and the sealing lip 108 is used to seal the sealing ring 103, and the sealing lip 108 is used to seal the sealing ring 10 3 and the gap between the clutch main housing 101 is filled and sealed, so that water is not easily immersed, so as to achieve the effect of water sealing, and water sealing is performed through the U-shaped groove 110. The gap between the sealing ring 103 and the clutch main housing 101 is filled and sealed by the U-shaped groove 110, so that water is not easily immersed, so as to achieve the effect of water sealing. The interval setting of the first water seal and the second water seal can effectively improve the sealing effect, and the interval staggered setting of the first water seal and the second water seal can effectively prevent liquid leakage, ensure that a stable sealing state is maintained during operation, and enhance adaptability. The interval staggered setting can make the water sealing system more balanced and stable, reduce vibration and impact force, thereby extending the overall service life, reducing maintenance costs, and making it easier to inspect and replace damaged seals.

[0026] The second embodiment of the present application is:

[0028] The utility model provides a tractor clutch housing, which also includes an outer heat dissipation fin 201 and an inner heat absorption fin 202 .

[0029] According to this specific embodiment, the outer heat dissipation fins 201 and the inner heat absorption fins 202 are used to absorb and dissipate heat inside the clutch main housing 101, thereby reducing the temperature inside the clutch main housing 101 and extending the service life of the clutch main housing.

[0030] Among them, there are multiple external cooling fins 201, each of which is fixedly connected to the cover body 102 and is located on one side of the cover body 102.
