Preferably, each filtering part comprises a filtering box, a fan and a filter screen;

The two filter boxes are embedded in the two supporting legs of the installation frame, each fan is respectively arranged in each filter box, and each filter screen is respectively arranged in each filter box and positioned on one side of each filter screen.

Preferably, openings are respectively formed in two side walls of each filter box, and a protection net is respectively arranged in each opening.

Preferably, four universal wheels are arranged on the lower wall of the mounting plate.

Advantageous effects

The technical scheme provides the classified sand screening machine, which realizes automatic and controllable flow speed blanking, can not cause stacking screening in the screening process, does not need to continuously carry out sand-lifting work manually, liberates manpower, is convenient to move, can also carry out dust-lifting filtration in the screening process, and protects the environment;

the technical scheme at least has the following technical effects:

The staff pours the sand that needs to sieve into the unloading incasement of assembly on the mounting bracket, after the assembly, through installing the programmable controller on it and control the operation, install the vibrations motor on the screen cloth and begin to operate, make the screen cloth vibrate, the electric putter of installing on the mounting bracket slowly drives the picture peg of connecting on its flexible end and slides between the slide and open, the sand in the unloading incasement can flow, electric putter drives the picture peg and removes, control sand unloading velocity of flow, improve screening efficiency, the sand of whereabouts falls to the screen cloth of vibrations and sieves.
