[0021] In this embodiment, the cleaning box 1 serves as the main place for cleaning coarse aggregates. The storage box 2 is fixedly installed on the top of the cleaning box 1 to store the coarse aggregates to be cleaned. The discharge pipe 3 at the bottom ensures that the coarse aggregates can smoothly enter the cleaning box 1. The discharge pipe 3 is provided with a quantitative valve 4, which can control the discharge speed of the coarse aggregates to ensure the stability and efficiency of the cleaning process.

The water supply pump 6 is a key component for providing water for cleaning. Its water inlet end is connected to the water supply equipment through the water inlet pipe 7 to ensure a stable water supply. The water outlet pipe 8 guides the water output by the water supply pump 6 into the cleaning box 1 to flush the coarse aggregates. By adjusting the flow of the water supply pump 6 and the arrangement of the water outlet pipe 8, flushing effects of different intensities can be achieved.

[0022] In a further preferred embodiment of the utility model, the driving mechanism includes a driving motor 9, a cam 10, a support rod 11, a connecting rod 12 and a round wheel 13, the driving motor 9 is fixedly mounted on the top of the cleaning box 1, the cam 10 is rotatably mounted on the cleaning box 1, the cam 10 is fixedly connected to the output shaft of the driving motor 9, the support rod 11 is slidably mounted on the cleaning box 1, the bottom end of the support rod 11 is connected to the screen plate 5, the connecting rod 12 is fixedly mounted on the top of the support rod 11, and the round wheel 13 is rotatably mounted on the connecting rod 12 and contacts with the cam 10.
