[0002] A water conservancy project is a project built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating disasters and bringing benefits. Water is an indispensable precious resource for human production and life. However, its natural state does not fully meet the needs of humans. Only by building water conservancy projects can the water flow be controlled, flood disasters be prevented, and the regulation and distribution of water volume be carried out to meet the needs of people's lives and production for water resources. During the construction process of water conservancy projects, gravel devices are often needed. However, due to the special construction environment of water conservancy projects, the gravel materials are often mixed with silt and water, and it is necessary to carry out drainage operations on the muddy water, which wastes manpower and time.

[0003] At present, there is a structure where a rotatable runner is provided below two crushing rollers. A number of discharging plates evenly distributed around the runner are fixedly connected to the runner. A through groove is provided on one side of the lower housing, and a discharging plate passing through the through groove is provided in the through groove. A water outlet is provided at the bottom on the side of the lower housing away from the through groove, which can separate gravel from muddy water and discharge it smoothly, improving the efficiency.
