The technical scheme for realizing the purpose of the utility model is as follows: the crawler excavator is characterized by also comprising at least two sets of mud scraping devices, wherein each set of mud scraping device comprises an oil cylinder, a guide device and a scraper knife; the guiding device comprises a guiding support fixed on the upper part of the chassis and a guiding push rod sliding on the guiding support, one end of the oil cylinder is hinged to the upper part of the chassis through a hinge seat, the other end of the oil cylinder is hinged to the guiding push rod, and the other end of the guiding push rod is fixedly connected with the scraper knife; the scraper knife is positioned on the upper side of the crawler beam, and the guide support is positioned on the lateral side of the hinged support in the left-right direction. In the utility model, the mud and stone residues on the upper side of the crawler beam can be removed by using the mud scraping device, thereby being convenient and labor-saving.
In the crawler-type excavator, the upper end of the scraper knife is provided with the guide part bent towards the pushing direction of the scraper knife, and the guide part enables soil and stone slag pushed by the scraper knife to overturn and fall towards the front of the pushing direction of the scraper knife at the top of the scraper knife, so that the soil and stone slag cannot fall to the rear of the scraper knife.
In the crawler excavator, the guide support comprises a support and a guide cylinder, the support is fixed on the chassis, the guide cylinder is fixed on the support, and the guide push rod is located in an inner hole of the guide cylinder.
In the crawler excavator, a plurality of chain wheel supporting seats are arranged at the front and the back of the top of the crawler beam at intervals, and the scraper knife is positioned in front of the chain wheel supporting seat at the forefront.
Compared with the prior art, in the utility model, the mud and stone residue on the upper side of the track beam can be removed by using the mud scraping device, thereby being convenient and labor-saving.
