[0009] Preferably, the outer side of the center cylinder is provided with a first gear, and the inner wall of the first gear is fixedly connected to the outer surface of the center cylinder.

In addition, controlling the downward movement of the hydraulic rod can also push the scraping cylinder to scrape off the urea particles adhered to the surface of the center cylinder, thereby effectively avoiding the need to wash off the urea particles adhered to the center cylinder with water, which ultimately leads to the problem of reducing the service life of the urea solution equipment.
