[0028] like Figure 1 and Figure 2, the power assembly 3 drives the brush assembly 1 to rotate through the front drive assembly 2, and the brush assembly 1 rotates on the inner wall of the barrel 6 to clean the residue on the inner wall of the barrel 6. At the same time, the power assembly 3 drives the front drive assembly 2 to move forward and backward, and the front drive assembly 2 is connected to the rear drive assembly 4 through the intermediate connecting rod assembly 5, and the front drive assembly 2 and the rear drive assembly 4 move synchronously. The front drive assembly 2 and the rear drive assembly 4 are respectively provided with four running wheels that can be telescopic along the radial direction of the barrel under the telescopic action of the telescopic assembly. The running wheels of the front running wheel assembly and the rear running wheel assembly are respectively arranged in 2×2, and each running wheel abuts against the inner wall of the barrel 6, so that the front drive assembly 2 can smoothly drive the rear drive assembly 4 to move in the barrel 6.

[0029] like Figures 1 to 5 The front drive assembly 2 includes a front fixed frame 21, a power transmission assembly 22, a front fixed pin assembly 23, a front running wheel assembly 24, a first connecting rod assembly 25 and a second connecting rod assembly 26. The power transmission assembly 22 is connected to the power assembly 3, the front running wheel assembly 24 is connected to the power transmission assembly 22, the front fixed pin assembly 23 is fixed to the front fixed frame 21, the two ends of the first connecting rod assembly 25 are respectively movably connected to the front fixed pin assembly 23 and the front running wheel assembly 24, and the two ends of the second connecting rod assembly 26 are respectively movably connected to the front running wheel assembly 24 and the front end of the intermediate connecting rod assembly 5.
