[0002] As an important engineering machinery, excavator has played an increasingly important role in the production of modern society. The main support of the excavator is hinged to the base of the excavator through a rotary bearing, and the rotation function of the main support of the excavator is realized through the driving of the motor. However, due to the accumulation of soil around the rotary bearing during the operation of the excavator, impurities enter the interior of the rotary bearing, pollute the grease, and cause engine abnormal noise and other faults. After searching, a kind of excavator soil cleaning device and excavator of Chinese patent number CN204001029U are found, wherein the excavator soil cleaning device is installed on the main support of the excavator, the main support is hinged to the base of the excavator through a rotary bearing, and the excavator soil cleaning device comprises: the utility model provides a kind of excavator, including any one of the above-mentioned excavator soil cleaning device.
