[0011] Preferably, a second discharge pipe is provided at the lower end of the sieving box, and a second solenoid valve is provided on the second discharge pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This device can dry and screen the sand and gravel, thus preventing the sand and gravel from sticking to the inner wall of the screening box due to the wet surface of the sand and gravel during screening.

[0014] (2) This device sets up a drying box on the top of the screening box so that the sand and gravel can be dried in the drying box before entering the screening box for filtration and separation. This avoids a large amount of sand and gravel remaining in the screening box, reduces the difficulty of cleaning the screening box, and avoids the blockage of the first and second filter screens due to sand and gravel residue.

[0015] (3) This device improves the drying effect of sand and gravel by setting a drying hood on the top of the first filter screen and setting a second heating tube inside the drying hood.
