The fixed detection mechanism 4 includes a mounting horizontal plate 7. The side of the mounting horizontal plate 7 close to the inner wall of the shell 1 is welded to the inner wall of the shell 1. A cleaning mechanism 2 is arranged at the bottom of the inner cavity of the shell 1. The cleaning mechanism 2 includes a cleaning belt 10. The bottom of the cleaning belt 10 passes through the bottom of the shell 1.

[0019] See also Figure 2 An L-shaped plate 6 is welded on the right side of the shell 1, a cleaning paddle 14 is welded on the inner side of the L-shaped plate 6, and the left side of the cleaning paddle 14 is slidably connected to the connection point of the surface of the cleaning belt 10.
