[0033] Working principle: When using this device, install this decontamination machine at the designated position for decontamination work. When performing decontamination work, start the first motor 3. The output end of the first motor 3 rotates, driving the rotating shaft 2 fixedly connected to the output end of the first motor 3 to rotate. The grille body 4 sleeved on the outer surface of the rotating shaft 2 rotates, so that the lower rotating shaft 2 rotates. When the grille body 4 rotates, the garbage in the sewage tank is driven by the grille body 4 to rise and enter the interior of the upper part of the decontamination machine body 1. When the garbage reaches the left side of the grille body 4, it is scraped off by the first scraper 5 and reaches above the collection plate 9. Then, it enters the circular hole opened on the collection plate 9 through the inclined groove opened on the collection plate 9. The second motor 8 is started, and the output end of the second motor 8 drives the cleaning rotating rod 6 fixedly connected to its output end to rotate. The rotation of the cleaning rotating rod 6 drives the two cleaning plates 7 fixedly connected to the cleaning rotating rod 6 to rotate. The two cleaning plates 7 rotate inside the circular hole of the collection plate 9, bringing the garbage inside the circular hole to the left end opening of the decontamination machine body 1 and sending it out of the decontamination machine body 1. When the first scraper 5 scrapes the garbage on the grille body 4, some garbage may fall onto the upper surfaces of the two first triangular plates 10. At this time, the two first hydraulic telescopic rods 11 are started, driving the two mounting plates 12 fixedly connected to their telescopic ends to move downward. The second scraper 15 below the two mounting plates 12 comes into contact with the corresponding first triangular plate 10. Then, the mounting plate 12 continues to move, and the second scraper 15 drives the T-shaped plate 14 to move into the T-shaped groove 13. The upper end of the T-shaped plate 14 is squeezed by the second triangular plate 16, so that the two second scrapers 15 approach each other. When the two second scrapers 15 approach each other, the garbage that may remain on the upper surface of the first triangular plate 10 is scraped into the inclined groove of the collection plate 9. When it reaches the circular hole, it is sent out of the interior of the decontamination machine body 1 by the two cleaning plates 7, thus cleaning the garbage on the first triangular plate 10. When the second scraper 15 drives the first hydraulic telescopic rod 11 and the grille body 4 to move upward, the rectangular plate 18 is also squeezed by the T-shaped plate 14. The rectangular plate 18 moves upward, squeezing the corresponding damper 17 and spring 19, causing them to compress. When the second scraper 15 finishes cleaning the garbage, the two second motors 8 move upward, and the extrusion on the second scraper 15 and the T-shaped plate 14 disappears. The damper 17 and the spring 19 rebound, causing the corresponding rectangular plate 18 to return to its original position, so that the rectangular plate 18 drives the T-shaped plate 14 and the second scraper 15 back below the T-shaped groove 13. Then, the second hydraulic telescopic rod 20 is started, pushing the T-shaped plate 14 and the second scraper 15 back to their original positions for convenient reuse next time.

[0034] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
