[0026] A cleaning assembly is arranged in the support tube 3, and the cleaning assembly includes a plurality of sleeves 17 equidistantly and circumferentially fixedly connected to the No. 2 rotating shaft 14, a No. 1 cleaning plate 18 is slidably connected in each of the plurality of sleeves 17, two No. 2 springs 19 are fixedly connected between the upper surfaces of the plurality of No. 1 cleaning plates 18 and the inner top surface of the sleeve 17, a No. 2 cleaning plate 22 is fixedly connected to the bottom surfaces of the plurality of No. 1 cleaning plates 18, the length of the No. 2 cleaning plate 22 is greater than the radius of the support tube 3, so that the plurality of No. 2 cleaning plates 22 contact the ground, which can effectively avoid the influence of large particles and gravel on the stability of the mechanism, and the height of the support tube 3 is greater than the sum of the heights of the No. 1 sleeve 4 and the support plate 20, so that the final main load-bearing is borne by the support tube 3, so as to ensure that the mechanism effectively avoids the influence of large particles and gravel on its own stability.
