The top of the first storage box 3 is open, and the first screening plate 5 is arranged on the top of the first storage box 3. The first screening plate 5 is used to receive the sand and gravel after the first screening output by the screening device 2, and to perform a second screening on the sand and gravel after the first screening. The interior of the first storage box 3 is hollow, and the interior of the first storage box 3 is used to receive and store the sand and gravel after the second screening. Specifically, a plurality of sieve holes are provided on the first screening plate 5, and the sand and gravel are screened for the second time through each sieve hole. The sand and gravel smaller than the diameter of the sieve hole in the sand and gravel after the first screening falls into the first storage box 3 through the sieve hole, and the sand and gravel larger than the diameter of the sieve hole is retained on the first screening plate 5.
[0026] The first screening plate 5 is partially inserted into the second storage box 4, and is used to transport the sand and gravel retained on the first screening plate 5 to the second storage box 4.

Specifically, since the second storage box 4 and the support column 1 are respectively arranged on the two opposite sides of the first storage box 3, the top of the first storage box 3 gradually inclines downward from the side of the support column 1 to the side of the second storage box 4, and the top of the first storage box 3 is higher on the side of the support column 1, and lower on the side of the second storage box 4. Since the first screen plate 5 is arranged on the top of the first storage box 3, the first screen plate 5 is in an inclined state, and gradually inclines downward from the side of the support column 1 to the side of the second storage box 4. In this way, it is convenient for the sand and gravel retained on the first screen plate 5 to slide into the second storage box 4.

Specifically, the support rod 245 and the second screening plate 23 are relatively fixed, so the support rod 245 is fixed, and a penetration hole is opened at the bottom of the housing 242 corresponding to the support rod 245, and a bearing is arranged in the penetration hole, and the support rod 245 is penetrated and connected to the bearing, and the inner ring of the bearing does not rotate, and the outer ring rotates. In this way, the support rod 245 is fixed, and the housing 242 can rotate freely, so the support rod 245 does not affect the rotation of the housing 242. In specific implementation, the support rod 245 can be placed at the center of the housing 242.
[0046] The main gear 246 is disposed at the second end of the support rod 245 . The two stirring components are symmetrically disposed, and both stirring components are connected to the main gear 246 .

The staff can pull the pull rod 7 to pull out the drawer 6, and then store and utilize the sand and gravel in the drawer 6.
[0060] Preferably, the sieve hole diameter of the first sieve plate 5 is smaller than the sieve hole diameter of the second sieve plate 23; and / or, the top of the first storage box 3 is inclined and has a preset inclination angle, and the first storage box 3 is inclined downward from the side opposite to the second storage box 4 to the second storage box 4.
[0061] Combination Figures 1 to 5 The use process of the screening device is introduced as follows: Pour an appropriate amount of sand and gravel on the screening barrel 22 and the second screening plate 23, start the first driving motor 241, and the first driving motor 241 drives the housing 242 to rotate. The rotation of the housing 242 drives the rotation of the two connecting rods 243 and the two push rods 244, so that the gathered sand and gravel are dispersed for easy screening. At the same time, the rotation of the housing 242 drives the rotation of the two connecting shafts 248, and at the same time drives the driven gears 247 on the two connecting shafts 248 to rotate around the main gear 246, so that the two connecting shafts 248 rotate. The revolution and rotation of the two connecting shafts 248 drive the rotation of the stirring blades 249 thereon, thereby stirring the sand and gravel. The second drive motor 211 is started, and the second drive motor 211 drives the rotating block 212 to rotate, and then drives the connecting rod 213 to rotate, and the connecting rod 213 drives the mounting body 214 to move up and down, and the mounting body 214 drives the screen barrel 22 to move up and down, so that the sand and gravel of appropriate size pass through the second screening plate 23 and fall onto the first screening plate 5. Since the first screening plate 5 is in an inclined state, the sand and gravel larger than the size of the first screening plate 5 rolls along the first screening plate 5 into the second storage box 4, and the sand and gravel smaller than the size of the first screening plate 5 falls into the drawer 6 in the first storage box 3. When the sand and gravel in the drawer 6 accumulate to a certain amount, the staff pulls the pull rod 7 to pull out the drawer 6 to clean the sand and gravel, thereby achieving the purpose of classifying and screening the sand and gravel.
[0062] In summary, in this embodiment, the screening device 2 performs the first screening on the loaded sand and gravel, and the vibration of the screening device 2 itself can enhance the screening effect on the sand and gravel, and speed up the screening speed. The first screening plate 5 receives the sand and gravel after the first screening, and performs a second screening on it. The first storage box 3 receives the sand and gravel after the second screening, and the second storage box 4 receives the sand and gravel retained on the first screening plate 5. In this way, the sand and gravel are screened twice, which effectively improves the screening effect of the sand and gravel, and the sand and gravel after the second screening are separately stored, which improves the screening quality, speeds up the screening efficiency, and saves the screening time.
