[0001] This utility model relates to the field of cleaning equipment technology, specifically a washing device for riprap concrete dam blocks. Background Technology

[0002] Washing the riprap in a rockfill concrete dam is an important part of the construction process. Its quality and efficiency directly affect the quality of subsequent construction and the stability of the overall project. The main purpose of washing the riprap in a rockfill concrete dam is to remove the mud and impurities from the surface of the riprap and ensure that the mud content of the riprap is no more than 0.5% in order to meet the quality requirements of rockfill concrete construction.

[0003] When washing the boulders of a rockfill concrete dam, a washing device is required. In the prior art, the washing device uses a conveyor belt to transport the boulders and a flushing structure on the upper side to wash them. However, in this method, the conveyor belt cannot rotate the boulders during washing, making it difficult to clean the bottom of the boulders. Furthermore, it is even more difficult to wash away firmly adhered mud and impurities on the boulders. Therefore, the quality of washing the boulders of the rockfill concrete dam cannot be guaranteed. To address these issues, this application proposes a boulders washing device for rockfill concrete dams. Utility Model Content
