The second discharge guiding box is located below the first discharge guiding box. The fine sand conveying mechanism includes a conveying assembly and a driving mechanism. The conveying assembly includes two second support plates arranged below the two first support plates. Two first rotating shafts are rotatably connected between the two second support plates. The two first rotating shafts are respectively located on the left and right sides of the two second support plates. The front side of the first rotating shaft located on the left rotates through the outer wall of the front second support plate and extends to the outside.

[0008] Furthermore, circular rollers are fixedly connected to the outer walls of the two first rotating shafts, and a conveyor belt is sleeved on the two circular rollers.

[0009] Further, the driving mechanism includes a motor fixedly connected to the front extension of the left rotating shaft I. A motor sleeve is fixedly connected to the outer wall of the motor, and the rear side of the motor sleeve is fixedly connected to the second support plate located at the front side.

[0010] Further, the vibration screening assembly includes a first vibration screening assembly, a second vibration screening assembly, and a transmission assembly. The first vibration screening assembly includes two support legs respectively arranged on the front and rear sides of the two first support plates. The tops of a plurality of the support legs are fixedly connected with rectangular connecting plates I, and rectangular connecting plates II are arranged above a plurality of the rectangular connecting plates I.

[0011] Further, strong springs are fixedly connected between a plurality of the rectangular connecting plates I and a plurality of the rectangular connecting plates II.

[0013] Further, an eccentric shaft is fixedly connected to the outer wall of the rotating shaft II. An adaptor collision block is fixedly connected to the bottom of the second filter plate. The eccentric shaft is adapted to the adaptor collision block.

[0014] Further, the transmission assembly includes a small belt pulley fixedly connected to the front extension of the right rotating shaft I.

[0015] The utility model has the following beneficial effects:

[0016] 1. By arranging the conveying mechanism, while the rotating shaft I drives the device to vibrate, it will also drive the conveyor belt to rotate through the round roller, and convey the finer sand and gravel screened out by the device through the vibrating screen to the next processing area, so as to realize continuous and stable fine sand transportation. Compared with manual handling, the transportation speed and work efficiency are greatly improved, the time waste caused by manual intermittent operation is avoided, the whole recycling process is made smoother, the heavy physical labor of workers is reduced, and the fatigue and injury risks caused by manual handling are reduced;

[0017] 2. By setting up a vibrating screening mechanism, when it is necessary to recycle sand and gravel, the motor can be started. The motor drives the first rotating shaft to rotate. The first rotating shaft drives the second rotating shaft on the U-shaped support plate to rotate rapidly through the small pulley, large pulley and belt, thereby driving the eccentric shaft to rotate. When the protruding part of the eccentric shaft rotates to the contact part with the matching collision block, the second filter plate will drive the sand and gravel on the first filter plate and the second filter plate to move upward under the action of the strong spring. When the protruding part on the eccentric shaft disengages from the matching collision block, the second filter plate and the sand and gravel on the second filter plate move downward. When the second filter plate moves downward, the bearing plate will limit the downward movement of the second filter plate to a certain height, thus avoiding damage to the second rotating shaft caused by the downward movement of the second filter plate. In this way, reciprocating, vibration is generated under the action of the strong spring. Larger sand and gravel remain on the first filter plate, and relatively smaller sand and gravel will fall onto the second filter plate. The sand and gravel on the second filter plate will be further screened by the second filter plate. At this time, the smaller sand and gravel will fall on the conveyor belt, completing the screening of the sand and gravel, enabling precise grading of waste sand and gravel, effectively separating sand and gravel of different particle sizes through the vibration effect, facilitating subsequent classification treatment and reuse, and also removing impurities and fine particles mixed in the waste sand and gravel, making the recycled sand and gravel purer and improving its reuse value.

[0018] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

While the first rotating shaft 212 drives the device to generate vibrations, it will also drive the conveyor belt 214 to rotate through the round roller 213, transporting the finer sand and gravel screened by the vibrating sieve of the device to the next processing area, enabling continuous and stable fine sand transportation. Compared with manual handling, the transportation speed and work efficiency are greatly improved, avoiding the time waste caused by intermittent manual operation, making the entire recycling process smoother, reducing the heavy physical labor of workers, and reducing the fatigue and injury risks caused by manual handling. After the screening is completed, the larger sand and gravel will be vibrated out of the device through the first discharge guiding box 103, and the relatively smaller sand and gravel will be vibrated out of the device through the second discharge guiding box 104.
