[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 , a slewing bearing mounting seat for an excavator with a protective effect, comprising a bearing mounting seat body 1, wherein a protective component is arranged on the bearing mounting seat body 1;

[0021] The protective component includes a connecting sleeve 2, the connecting sleeve 2 is arranged to wrap the supporting mounting seat body 1, and an annular sheet 3 is arranged on one side of the connecting sleeve 2 close to the supporting mounting seat body 1, two annular sheets 3 are arranged, which are used to wrap the upper and lower ends of the supporting mounting seat body 1 so that the connecting sleeve 2 is fixed on the supporting mounting seat body 1, the lower end of the connecting sleeve 2 is slidably connected with an extension sleeve 4, the upper end of the connecting sleeve 2 is provided with a plurality of extension sheets 5, the extension sheets 5 are directly provided with a connecting film, a round sleeve 6 is also provided on the extension sheet 5, and a tying rope 7 is provided in the round sleeve 6, one of the extension sheets 5 is also inserted with a connecting pipe 8, and a rubber plug 9 is provided on the connecting pipe 8, and the connecting pipe 8 is provided with the rubber plug 9, and the connecting pipe 8 is provided to cooperate with the rubber plug 9, so as to add lubricating oil to the supporting mounting seat body 1 during daily maintenance;

[0022] In the above design, the connecting sleeve 2 is sleeved on the supporting mounting seat body 1, and the extension sleeve 4 is against the walking structure of the lower half of the excavator, thereby realizing all-round protection of the supporting mounting seat body 1, and the extension piece 5 located at the upper end of the connecting sleeve 2 is rotated and bent after being against the lower surface of the excavator cab, thereby pressing against the lower surface of the cab to prevent splashing gravel, slag and other particles from entering the supporting mounting seat body 1, and the gaps between multiple extension pieces 5 are sealed by a connecting film with good elasticity, ultimately achieving the purpose of protecting the slewing bearing installation and extending the service life of the slewing bearing mounting seat body 1.

[0024] In this design, due to the different structures of the excavators and the errors during assembly, the bending and expansion states of the extension piece 5 after it abuts against the cab are also different. In addition, the excavator vibrates greatly during use, and the rubber mold is prone to tearing. Therefore, multiple rubber ropes 10 are provided to reinforce the rubber membrane 12, so that even if the rubber membrane 12 is torn, the crack will stop at the rubber rope 10, thereby ensuring the protective effect of the connecting membrane.
