There are two sets of sliding rods 7 and two sets of sliding sleeves 6, which are symmetrically arranged on both sides of the screening frame 301. In this embodiment, by setting up the screening component 3, the dual-axis motor 303 drives the turntable 304 to rotate. The turntable 304 drives the screening frame 301 to reciprocate through the connecting rod 305 and the movable rod 306, so that the sand and gravel are continuously turned over in the screening frame 301. This ensures that the stone can be continuously rolled and screened, improves the screening effect of sand and gravel, and also speeds up the screening speed of stone, thereby improving the working efficiency of the screening equipment. During the movement of the screening frame 301, the sliding sleeve 6 fixedly connected to the side of the screening frame 301 slides on the surface of the sliding rod 7 fixedly connected inside the housing 2. There are two sets of sliding rods 7 and two sets of sliding sleeves 6, which are symmetrically arranged on both sides of the screening frame 301. They play a guiding and stabilizing role in the movement of the screening frame 301, ensuring that the screening frame 301 moves smoothly during the screening process and improving the screening effect.

[0018] Please see Figure 1 , Figure 2 and Figure 4 The cylinder 1 has a through hole 4 on its surface, which connects the cylinder 1 and the shell 2. A discharge port 8 is provided on the surface of the cylinder 1, and a hinged door 10 is movably connected to the surface of the cylinder 1. The position of the door 10 corresponds to the position of the discharge port 8. A discharge assembly 5 is provided inside the cylinder 1, which matches the discharge port 8. The discharge assembly 5 is used to discharge sand and gravel. A conical boss 11 is provided inside the cylinder 1, and the discharge assembly 5 matches the conical boss 11. The discharge assembly 5 includes a first rotating shaft 501, which is fixedly connected to the double shaft. At the lower end of the output shaft of motor 303, the lower end of the first rotating shaft 501 is fixedly connected to the first sprocket 502, and the surface of the first sprocket 502 is connected to the chain 505. The surface of the conical boss 11 is connected to the second rotating shaft 503 through bearing transmission. The lower end of the second rotating shaft 503 is fixedly connected to the second sprocket 504. The first sprocket 502 and the second sprocket 504 are connected through chain 505 transmission. The surface of the second rotating shaft 503 is fixedly connected to the scraper 506, and the lower surface of the scraper 506 overlaps the upper surface of the conical boss 11. The scraper 506 is made of steel.

[0019] In this embodiment, by setting up a discharge assembly 5, the first rotating shaft 501 is driven to rotate by a dual-shaft motor 303. The first sprocket 502 and the second sprocket 504 are driven by a chain 505, causing the scraper 506 on the second rotating shaft 503 to rotate. The scraper 506 scrapes the screened sand and gravel out from the discharge port 8, making it convenient for workers to use a mobile trolley to align with the discharge port and collect the discharged sand and gravel. This brings convenience to the use of the stone screening equipment. With the cooperation of the conical boss 11, the screened sand and gravel slide naturally down the inclined surface of the conical boss 11 under the action of gravity, and ensures that the stone is concentrated in the discharge area. When cleaning and maintenance of the equipment is required, open the door 10, which is connected to the surface of the cylinder 1 by a hinge. The position of the door 10 corresponds to the position of the discharge port 8. The staff can clean and maintain the inside of the cylinder 1 through the door 10 to keep the equipment clean and in good operating condition.

[0020] The working principle and usage process of this utility model are as follows: First, the sand and gravel to be screened is poured into the screening frame 301 inside the shell 2 through the feed port at the top of the shell 2. The dual-axis motor 303 is started, and the turntable 304 at the upper end of the output shaft of the dual-axis motor 303 starts to rotate. The turntable 304 drives the screening frame 301 to reciprocate through the connecting rod 305 and the movable rod 306 connected by the pin. The sand and gravel in the screening frame 301 are constantly turned over under the reciprocating motion of the screening frame 301. Next, sand and gravel smaller than the sieve holes of the screening frame 301 fall through the sieve holes and enter the cylinder 1. The staff only needs to move the collection trolley to the discharge port 8 and open the hopper door 10. At the same time, the dual-shaft motor 303 rotates, which drives the first rotating shaft 501 to rotate. The first sprocket 502 at the lower end of the first rotating shaft 501 drives the second sprocket 504 to rotate through the chain 505. The second sprocket 504 is fixedly connected to the second rotating shaft 503. The scraper 506 fixedly connected to the surface of the second rotating shaft 503 rotates accordingly. At this time, the scraper 506 scrapes the screened sand and gravel inside the cylinder 1 out from the discharge port 8 and falls into the collection trolley. Finally, after the sand and gravel inside the cylinder 1 has been discharged, the silo door 10 is closed, and the large sand and gravel particles remaining inside the screening frame 301 are manually cleaned using cleaning tools. At the same time, the workers also manually unclog the mesh in the screening frame 301, which facilitates the subsequent screening of sand and gravel.
