Description

Technical Field

[0001] The utility model relates to the technical field of tractor gearboxes, in particular to an auxiliary replacement device for tractor gearbox oil. Background Art

[0002] At present, the replacement of tractor transmission oil is usually done by opening the oil drain port to allow the transmission oil to flow out of the transmission automatically. However, after long-term use, the transmission oil usually contains foreign matter such as dust and blocky oil stains, which makes it difficult to flow when the transmission oil is replaced, and the replacement efficiency is low. In addition, whether it is an automatic transmission or a dual-clutch transmission, they will generate a lot of heat during operation. If the heat is not dissipated in time, it will seriously affect the life and performance of the transmission. The transmission usually dissipates heat through the coolant shared with the engine, but at the same time, a heat dissipation base with a large number of heat sinks is usually connected to the outside of the transmission. The heat is transferred to the heat dissipation base through the surface of the transmission, and most of the heat is transferred to the heat sink. The heat sink is exposed to the air and can directly exchange heat with the air, thereby cooling the transmission. However, tractors usually need to operate in fields, woodlands and other environments. During the operation, the heat sink is easily covered by foreign matter such as mud and crop waste, which seriously affects the use of the heat sink. Utility Model Content
