The mud cleaning block 211 is engaged with an external slot of the inner support wheel 111, so that when the mud cleaning block 211 moves from back to front, the mud adhered to the external slot of the inner support wheel 111 is cleaned.

[0031] A connecting rod 212 for supporting the pushing block 210 is fixedly installed at the rear end of the pushing block 210, and an arc block 220 for cooperating with the limiting assembly 300 to limit the connecting rod 212 is fixedly installed at one end of the connecting rod 212, and the arc block 220 slides in the groove cavity of the sliding groove 311. A limiting tube 221 is fixedly installed at the rear end of the arc block 220, and one end of the cylinder 230 is fixedly installed on the limiting tube 221. The outer wall of the limiting tube 221 is fixedly installed with reinforcing ribs 222 for tightening the arc block 220. The strength of the arc block 220 is increased by setting the reinforcing ribs 222. A cylinder 230 for controlling the arc block 220 to move forward and backward is installed at one end of the limiting tube 221. By starting the cylinder 230, the arc block 220 is pushed, so that the arc block 220 pushes the connecting rod 212, driving the push block 210 to move forward, and the mud clearing block 211 clears the mud from the external slot of the inner support wheel 111.

[0032] A limiting assembly 300 for limiting the cleaning assembly 200 is installed at the rear end of the cleaning assembly 200. The limiting assembly 300 includes an arc sleeve 310. A slide groove 311 is provided inside the arc sleeve 310 for the arc block 220 to be extended and retracted. A limiting plate 320 for limiting the cylinder 230 is fixedly installed at the rear end of the groove cavity of the slide groove 311. The cylinder 230 is fixedly installed at the front end of the limiting plate 320. A hole cavity for the connecting rod 212 to slide is provided at the front end of the arc sleeve 310. A threaded hole 312 is provided at the rear end of the arc sleeve 310 to facilitate the locking of the closing assembly 400 with the bolt 420.

[0033] A closing component 400 for limiting the limit component 300 is installed at the rear end of the limit component 300. The closing component 400 includes a sealing cover 410 for blocking the slide groove 311, and the sealing cover 410 slides in the groove cavity of the slide groove 1 510. Slide blocks 412 are fixedly installed on both sides of the sealing cover 410, and the slide blocks 412 slide in the groove cavity of the slide groove 2 511. A limit block 411 is fixedly installed at the lower end of the sealing cover 410, and a hole cavity for limiting the tension spring 520 is opened in the middle of the limit block 411. One end of the tension spring 520 is fixedly installed on the limit block 411 to facilitate the tension spring 520 to pull the sealing cover 410. A bolt 420 for matching the threaded hole 312 to lock the sealing cover 410 is installed at the rear end of the sealing cover 410.

[0034] Limiting devices 002 are installed at the front and rear ends of the connecting column 110. Four mud cleaning devices 001 and limiting devices 002 are provided. The limiting device 002 is fixedly installed on one side of the connecting column 110. The limiting device 002 includes a supporting assembly 500. A slide groove 510 for sliding the sealing cover 410 is provided in the middle of the supporting assembly 500. Slide grooves 511 for sliding the slider 412 are provided on both sides of the groove cavity of the slide groove 510. A tension spring 520 is fixedly installed at the lower end of the supporting assembly 500 for cooperating with the limiting block 411 to pull the sealing cover 410.

[0035] When it is necessary to clear the mud from the outer groove of the inner wheel 111, the cylinder 230 is started so that the cylinder 230 pushes the arc block 220, so that the connecting rod 212 drives the push block 210 to approach the inner wheel 111, and the mud clearing block 211 is engaged with the outer groove of the inner wheel 111. The cylinder 230 continues to drive the arc block 220 to slide in the groove cavity of the slide groove 311, so that the mud clearing block 211 clears the mud from the outer groove of the inner wheel 111, thereby preventing mud from being stuck in the middle of the inner wheel 111 and the track 112, causing damage to the track 112 or derailment.

[0036] By setting the slide groove 1 510, the excavator can clean the mud from the outer groove of the inner wheel 111 when it is moving, and the cleaning component 200 can clean the outer groove of the inner wheel 111 when the inner wheel 111 is rotating. When the push block 210 cleans the outer groove of the inner wheel 111, the mud cleaning block 211 slides in the outer groove of the inner wheel 111, and the rotation of the inner wheel 111 drives the cleaning component 200 to revolve around the inner wheel 111, thereby driving the limiting component 300 and the closing component 400 to rotate, so that the sealing cover 410 slides in the groove cavity of the slide groove 1 510, and the limiting block 411 slides in the groove cavity of the slide groove 2 511. When the cylinder 230 cooperates with the arc block 220 to drive the push block 210 away from the inner wheel 111, the tension spring 520 cooperates with the limiting block 411 to pull the sealing cover 410 downward, so that the closing component 400 is reset. When there is no need to clean the outer groove of the inner support wheel 111 , the cylinder 230 cooperates with the arc block 220 to drive the push block 210 away from the inner support wheel 111 .
