Abstract

La présente invention concerne une rondelle de chargement avant et son système de pulvérisation visent à résoudre le problème de la structure de montage complexe d'un dispositif de pulvérisation d'une rondelle de chargement avant ayant une fonction de pulvérisation en circulation et son coût élevé de fabrication. La rondelle de chargement avant comprend un corps de machine (1), un tambour externe (2) disposé de manière fixe dans le corps de machine (1), un tambour interne (3) disposé de manière à pouvoir tourner dans le tambour externe (2), un joint de fenêtre (5) relié entre le corps de machine (1) et le tambour externe (2), et un système de pulvérisation. Le système de pulvérisation comprend une pompe de circulation (8), un tube de sortie d'eau (9) et une pluralité de buses (10). La pompe de circulation (8) est disposée sur le corps de machine (1) ou le tambour externe (2). Un orifice d'entrée d'eau de la pompe de circulation (8) est raccordé au tambour externe (2), et son orifice de sortie d'eau est raccordé à la pluralité de buses (10) respectivement à l'aide du tube de sortie d'eau. La pluralité des buses (10) sont disposées sur le joint de fenêtre (5). Lorsqu'elle se trouve en fonctionnement, la pompe de circulation (8) pompe l'eau de lavage dans le tambour externe (2) vers la pluralité des buses (10), et la pluralité des buses (10) pulvérisent l'eau de lavage dans le tambour interne (3). La buse présente une structure de montage simple, conservant ainsi la structure d'origine du tambour externe et ayant un faible coût de fabrication.
