The utility model discloses a cleaning device for a tailing conveying belt. The cleaning device is arranged at the end of the discharging side of the conveying belt. Comprising a first-stage sweeping mechanism, a second-stage sweeping mechanism and a third-stage sweeping mechanism which are sequentially arranged in the running direction of a conveying belt, the first-stage sweeping mechanism is provided with a polyurethane scraper blade with the fitting degree adjustable and an outer curved surface part arranged at the end of the conveying belt, and the second-stage sweeping mechanism is provided with a T-shaped metal scraper. The third-stage cleaning mechanism comprises a high-pressure washing assembly, a cleaning brush and a water scraping assembly which are sequentially arranged. The second-stage cleaning mechanism and the third-stage cleaning mechanism are arranged on the lower surface of the plane part in front of the first set of return stroke carrier rollers of the return stroke section of the conveying belt. The three stages of cleaning mechanisms are arranged on the return stroke section of the conveying belt to sequentially remove slurry, coarse sand, fine sand, surface texture of the conveying belt and residual particles in pits, the surface of the conveying belt is cleaned in a grading mode, the cleaning effect is excellent, abrasion of the surface of the return stroke carrier roller is effectively avoided, the service life is prolonged, and the maintenance cost is reduced.

The utility model discloses a swing flushing and blow-drying structure for a self-cleaning pedestal pan, which comprises a cleaning box body arranged behind a pedestal pan main body, a pedestal pan seat ring capable of being opened and closed is arranged on the pedestal pan main body, the pedestal pan seat ring can rotate into the cleaning box body, a driving unit and a flushing and blow-drying unit are arranged in the cleaning box body, and the driving unit is connected with the flushing and blow-drying unit. The flushing and blow-drying unit comprises at least one flushing pipe and an air drying pipe, the flushing pipe is connected with an external water source with pressure, the air drying pipe is connected with the fan, outlets of the flushing pipe and the air drying pipe face a toilet seat ring located in the cleaning box body, the driving unit is connected with the flushing and blow-drying unit, and the driving unit can drive the flushing pipe and the air drying pipe to rotate. Therefore, the outlets of the flushing pipe and the air drying pipe can cover the whole surface of the toilet seat in the cleaning box body. The flushing pipe and the air drying pipe are driven by the driving unit to perform multi-degree-of-freedom compound motion, so that a cleaning blind area is effectively eliminated, and no-dead-corner cleaning of the surface of the toilet seat ring can be realized.
