[0035] The horizontal connecting plate 303 is fixedly connected between the left and right two extended end guide plates 302 below motor 4.

[0036] Among them, the lower end of the rotating shaft of motor 4 is fixedly installed with wheel disc 401, and the connecting pin shaft 402 is vertically fixed below the position close to the edge of wheel disc 401, and the lower end of connecting pin shaft 402 is connected with horizontal connecting plate 303.

[0037] In the embodiment two, on the basis of the embodiment one, the upper end of the inclined surface of coarse sand guide frame 5 is upwardly extended and connected to the edge of one end of sorting frame 1, the inclined surface of coarse sand guide frame 5 is uniformly provided with shunt guide plate 501, the end of shunt guide plate 501 close to sorting frame 1 is inwardly and upwardly curved, the edge of the end of coarse sand guide frame 5 away from sorting frame 1 is outwardly and horizontally extended as extension support plate 502, and the coarse sand passes through coarse sand outlet 201 and falls on shunt guide plate 501, and then is shunted through the shortest path from extension support plate 502.

[0038] The working principle of the embodiment is as follows:

[0039] Firstly, the sand and stone mixture is put into the sorting guard box 2 on the sorting frame 1. The sorting guard box 2 serves as a closed space, effectively preventing sand and stone splashing during the sorting process, ensuring the safety and cleanliness of the working environment. In the sorting guard box 2, the inverted "V"-shaped sorting screen 3 plays a key role. The sorting screen 3, through the uniformly arranged screen holes 301 on its surface, performs preliminary screening on the sand and stone mixture, allowing fine sand particles to fall into the fine sand guide tray 101 below, while larger stones or coarse sand are intercepted on the screen surface.

[0040] The movement of the sorting screen 3 is driven by the motor 4. The motor 4 drives the wheel disc 401 to rotate through its shaft, and the connecting pin shaft 402 on the wheel disc 401 is connected to the transverse connecting plate 303 at both ends of the sorting screen 3, thereby achieving the reciprocating vibration of the sorting screen 3. This vibration mode not only enhances the screening effect, but also promotes the rapid flow of coarse sand on the screen surface, avoiding the clogging of the screen holes.

[0041] During the screening process, fine sand falls through the screen holes into the fine sand guide tray 101 and flows along its inclined surface to the opening end below the sorting frame, finally completing the collection and discharge of fine sand. Coarse sand and stones, etc. larger particles, slide along the smooth bottom edge of the sorting screen 3 to the coarse sand outlet 201.

[0042] The side plates of the sorting guard box 2 on both sides of the coarse sand outlet 201 are provided with openings, so that the coarse sand can be smoothly discharged. The discharged coarse sand falls on the inclined surface of the coarse sand guide frame 5. The coarse sand guide frame 5 ingeniously utilizes the principle of gravity and flow separation, and the flow separation guide plate 501 on it disperses and guides the coarse sand to the shortest path, and finally falls stably through the extension plate 502, realizing the rapid collection and arrangement of the coarse sand.
