Furthermore, a feed inlet at the front end of the drum screen is externally connected with a sand inlet groove with an arc-shaped bottom. The bottom of the sand inlet groove is arc-shaped, and the radian of the bottom of the sand inlet groove is the same as that of a screen mesh of the rotary screen, so that sand in the sand inlet groove can completely enter the rotary screen.

Furthermore, the drum screen is obliquely arranged at an angle of 11.5 degrees, and the front end of the drum screen is higher than the rear end of the drum screen. The drum screen is properly inclined, and the coarse gravel sieved by the drum screen can fall into the coarse sand hopper by self.

Furthermore, the idler wheels at the bottom of the machine body platform are universal wheels.

Compared with the prior art, the movable river sand screening device designed by the patent of the utility model has the advantages that the whole screening device is arranged on a large machine body platform, and a plurality of universal wheels are arranged at the bottom of the platform, so that the screening device can be moved integrally, and the application is more flexible; moreover, a pretreatment mechanism is added in front of the main screening mechanism to pretreat the collected sand, remove large-particle sand and stone therein, and uniformly mix soil and the sand, so that the main screening mechanism can screen sand more quickly, and the efficiency is improved; and a sand receiving hopper and a coarse sand hopper are arranged under the roller screen to respectively carry and collect the fine sand and coarse sand which are screened out, and the fine sand and the coarse sand are respectively conveyed out by a conveyor belt, so that the whole sand screening process is neat and ordered.
