[0034] The function principle of the present application can be described by the following operation mode: When the mineral aggregate needs to be cleaned: Firstly, in the cleaning stage, the mineral aggregate is put into the rough washing box 1. Then, the motor is started, the motor drives the stirring rod 31 to start rotating, the stirring rod 31 is a hollow pipe, which is divided into two independent cavities by the circular block 33 in the inside, the upper half cavity is connected with clean high-pressure water through the water pump 32, and the lower half cavity is connected with the circulating turbid water extracted from the vibration plate 21 through the water suction pump.

[0035] At the same time, the multiple groups of stirring blades 37 fixed on the stirring rod 31 rotate to mechanically stir the mineral aggregate. The high-pressure water is sprayed outward through the tree-shaped through hole 35 in the middle of the stirring blade 37 and the high-pressure water pipe 36 in the inside.
