[0020] A stirring rod 207 is provided on the circumferential surface of the left side of the rotating shaft 202, and a breaking rod 208 is provided on the circumferential inner wall of the screen drum 206.

[0023] The working principle and use process of the utility model are as follows: before using the sand and gravel, it is necessary to screen them.

The servo motor 201 drives the rotating shaft 202 and the stirring rod 207 to rotate. The rotating shaft 202 rotates through the transmission mechanism 203 to drive the rotating rod 204 and the spur gear 205 to rotate. The spur gear 205 rotates through the gear ring to drive the screen drum 206 and the breaking rod 208 to rotate. The rotation direction of the screen drum 206 is opposite to that of the stirring rod 207, so that the stirring rod 207 and the breaking rod 208 stir and hit the sand and gravel inside the screen drum 206 more violently, and then the clumped sand and gravel are broken up, which is convenient for the screening of sand and gravel and improves the screening efficiency of sand and gravel. The screening rate is high, and during the screening process, the medium sand and fine sand pass through the filter holes of the screen drum 206 and fall onto the vibrating screen plate 603 below. At the same time, the rotation of the screen drum 206 drives the protrusion 601 on its outer surface to rotate. Then, the vibrating screen plate 603, in cooperation with the protrusion 601 and the spring 606, can perform vertical reciprocating vibration to vibrate and screen the sand and gravel on its upper surface. The fine sand passes through the filter holes of the vibrating screen plate 603 and falls below, and is then discharged and collected through the discharge port 28. The medium sand moves to the right through the vibration of the vibrating screen plate 603, and is discharged and collected through the discharge port 17. After the screening is completed, the sealing door 5 and the sealing cover on the left side of the screen drum 206 are opened to allow the coarse sand to flow out from the inside of the screen drum 206, and is then collected at the discharge port 17 to complete the screening of the sand and gravel.
