Description

Technical Field

[0001] The utility model relates to a crawler mud removal mechanism for an excavator, belonging to the technical field of excavator equipment. Background Art

[0002] When using an excavator, it is often necessary to work in environments such as mud and quagmire, which can easily cause mud to adhere to the tracks. This not only reduces the working efficiency of the excavator, but also increases the wear of the tracks, accelerates the aging of the excavator, and shortens the service life of the excavator. If there is too much mud on the tracks, it will also cause the excavator to travel unsteadily, increase the difficulty of operation, and increase the risk of accidents. Therefore, when using the excavator, a mud removal mechanism is often installed to remove the mud attached to the tracks to improve the use effect and extend the service life.

[0003] Chinese patent publication number CN206049840U discloses an automatic mud removal device for crawlers of excavators, including a crawler assembly, a lower frame, a mudguard assembly, a pressure plate, and a base. The crawler assembly is arranged on both sides of the lower frame, the base is fixedly arranged on the lower frame, the pressure plate is arranged above the base, the right end of the mudguard assembly is arranged between the pressure plate and the base, the left end of the mudguard assembly is arranged above the crawler assembly, and the left end of the mudguard assembly is extended to align with the outer edge of the crawler assembly. In this technical solution, since the mudguard is welded along the bevel, the mud will move along the mudguard to the outer edge of the crawler after being blocked by the mudguard and finally fall off, automatically removing the mud attached to the crawler assembly. However, this technical solution still has shortcomings. When in use, due to the unevenness between the chain connections of the crawler tracks, the mud inside the gaps cannot be cleaned during mud removal, resulting in poor mud removal effect. At the same time, mud splashing will occur during mud removal, affecting other workers on site. Therefore, it is very necessary to make improvements. Utility Model Content
