[0002] With the development of industrial production technology, good production processing equipment plays a very important role in industrial production development. Among them, screening devices are a prime example. A screening device is a tool specifically used to separate materials of different particle sizes into different grades of coarseness by passing them through screens with different gap sizes.

[0003] Screening devices on the market suffer from low screening efficiency and easy material accumulation on the screen. To address this, we propose a screening device for coated sand production. Utility Model Content

[0004] The purpose of this utility model is to provide a screening device for the production of coated sand, so as to solve the problems of low screening efficiency and easy accumulation of material on the screen in the screening devices mentioned in the background art.

The device comprises a first straight rod, a second straight rod at one end of the first straight rod, a locking block on the outer side of the second straight rod, the locking block being slidably connected to the second straight rod, a screen being installed at one end of the second straight rod, the screen being slidably connected to a support, a first bevel gear at one end of the first rotating shaft, a second bevel gear meshing with one side of the first bevel gear, a lead screw on one side of the second bevel gear, a slider on the side of the lead screw, an insert rod on the side of the slider, a fixing rod on the side of the slider, a scraper on the top of the slider, a first collecting groove at the bottom of the screen, second collecting grooves at the bottom of both sides of the screen, and a third collecting groove at the bottom right side of the screen cylinder.

[0006] The present invention further illustrates that the baffle is slidably connected to the feed inlet, and the feed inlet and the discharge outlet are located on the left side of the screen cylinder, and the discharge outlet is tilted to the right.

[0007] This utility model further illustrates that the screen cylinder is rotatably connected to the support, and the screen cylinder is tilted to the right.

[0008] The present invention further explains that the first gear and the second gear are meshed together, and the first straight rod forms a rotating structure with the second gear through the second rotating shaft, and the second straight rod is rotatably connected with the first straight rod.

[0009] The present invention further explains that the second bevel gear, the lead screw, and the bracket are rotatably connected, and two oppositely oriented spiral lines are opened on the outer side of the lead screw, which are connected end to end. The slider is inserted into the outer spiral line of the lead screw through two insert rods to form a reciprocating transmission structure with the screen.

[0010] This utility model further illustrates that the slider and the fixed rod are slidably connected, and the scraper and the screen are slidably connected.

[0011] The advantages of this utility model are:

[0012] 1. In the first screening of this film-coated sand production screening device, by pouring the material into the feed inlet, moving the baffle, and turning on the first motor, the material can flow into the screen cylinder. The rotation of the screen cylinder separates the larger material particles and they fall into the third collection trough, thus completing the screening of larger particles. The degree of movement of the baffle can change the falling speed of the material, which can better control the screening effect. At the same time, the rolling of the screen cylinder can make the material move continuously in the screen cylinder so as not to accumulate in the screen cylinder and affect the screening efficiency. The tilting of the screen cylinder to the right can make large particles roll to the third collection trough at the bottom right for collection.

[0013] 2. During the second screening, the screening device for coated sand production uses a second motor to drive the screen and scraper to reciprocate, allowing finer materials to be screened into the first collection trough and coarser particles to be collected into the second collection trough. This achieves screening of materials of different particle sizes. The reciprocating motion of the screen spreads the accumulated material out, thus accelerating the screening efficiency. The reciprocating motion of the scraper allows larger particles to be scraped into the left and right second collection troughs, while also spreading the accumulated material out, further accelerating the screening efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5This utility model provides a technical solution: a screening device for coated sand production, including a base 1, a support 2 mounted on the top of the base 1, an inlet 3 mounted above the support 2, a baffle 4 penetrating through the middle of the inlet 3, an outlet 5 mounted on the side of the inlet 3, a first motor 6 mounted above the support 2, a connecting frame 7 mounted on the output end of the first motor 6, a screen cylinder 8 mounted on the outer side of the connecting frame 7, a second motor 9 mounted on the top of the base 1, a first rotating shaft 10 mounted on the output end of the second motor 9, a first gear 11 mounted on the outer side of the middle of the first rotating shaft 10, a second gear 12 mounted on the side of the first gear 11, a second rotating shaft 13 mounted at the far end of the side of the second gear 12, and a first straight rod 14 mounted on the outer side of the second rotating shaft 13. A second straight rod 15 is provided at one end, and a locking block 16 is provided on the outer side of the second straight rod 15. The locking block 16 is slidably connected to the second straight rod 15. A screen 17 is installed at one end of the second straight rod 15, and the screen 17 is slidably connected to the support 2. A first bevel gear 18 is installed at one end of the first rotating shaft 10. A second bevel gear 19 is meshed on one side of the first bevel gear 18. A lead screw 20 is installed on one side of the second bevel gear 19. A slider 21 is provided on the side of the lead screw 20. An insert rod 22 is installed on the side of the slider 21. A fixing rod 23 is provided on the side of the slider 21. A scraper 24 is installed on the top of the slider 21. A first collection groove 25 is provided at the bottom of the screen 17. A second collection groove 26 is provided on the bottom of both sides of the screen 17. A third collection groove 27 is provided on the bottom right side of the screen cylinder 8.

[0022] Furthermore, the baffle 4 is slidably connected to the feed inlet 3, and the feed inlet 3 and the discharge outlet 5 are located on the left side of the screen cylinder 8, and the discharge outlet 5 is tilted to the right. By adjusting the degree of movement of the baffle 4, the opening size of the feed inlet 3 can be controlled, the speed at which the material enters can be controlled, and the rightward tilt of the discharge outlet 5 can allow the material to be poured out better.

[0023] Furthermore, the sieve cylinder 8 is rotatably connected to the support 2, and the sieve cylinder 8 is tilted to the right. The rotation of the sieve cylinder 8 allows finer materials to be sieved into the lower layer, while coarser and larger particles will fall from the right side into the third collection tank 27 for collection due to the rightward tilt of the sieve cylinder 8.

[0024] Furthermore, the first gear 11 and the second gear 12 are meshed together, and the first straight rod 14 forms a rotating structure with the second gear 12 through the second rotating shaft 13. The second straight rod 15 is rotatably connected to the first straight rod 14. The first gear 11 drives the second gear 12 to rotate, and the second gear 12 drives the second straight rod 15 to reciprocate, which can drive the screen 17 to reciprocate, thereby accelerating the screening efficiency.

[0025] Furthermore, the second bevel gear 19, the lead screw 20, and the support 2 are rotatably connected. The lead screw 20 has two oppositely rotating spirals connected end to end. The slider 21 is inserted into the spirals on the outside of the lead screw 20 through two insert rods 22 to form a reciprocating transmission structure with the screen 17. The second bevel gear 19 drives the lead screw 20 to rotate, so that the two oppositely rotating spirals connected end to end can drive the slider 21 to reciprocate through the insert rods 22.

[0026] Furthermore, the slider 21 is slidably connected to the fixed rod 23, and the scraper 24 is slidably connected to the screen 17. Through the reciprocating motion of the slider 21, the scraper 24 can be driven to reciprocate, scraping larger particles on the screen 17 to both sides and causing them to fall into the second collection tank 26.

[0027] Working principle:

[0028] For this type of screening device, the material is first poured into the inlet 3. Then, according to the user's needs, the baffle 4 is moved to make the material flow out of the outlet 5 at the user's desired speed. Then, the first motor 6 is turned on, driving the screen cylinder 8 to rotate. The screen cylinder 8 rolls larger material particles into the third collection tank 27 by tilting to the right, while the finer material particles fall onto the screen 17. Then, the second motor 9 is turned on, driving the first rotating shaft 10 to rotate. The first rotating shaft 10 drives the first gear 11 to rotate. The first gear 11 meshes with the second gear 12 and rotates. The second gear 12 drives the first straight rod 14 to move. The first straight rod 14 drives the second straight rod 15 to move under the constraint of the locking block 16. The screen 17 reciprocates, causing the material to spread evenly on it and increasing screening efficiency. Simultaneously, the first rotating shaft 10 drives the first bevel gear 18 to rotate, which meshes with the second bevel gear 19. The second bevel gear 19 drives the lead screw 20 to rotate, and the lead screw 20 drives the slider 21 to reciprocate under the constraint of the fixed rod 23 through two sets of spirals that rotate in opposite directions and are connected end to end. This causes the slider 21 to drive the scraper 24 to reciprocate, scraping larger material particles into the second collection troughs 26 on both sides of the screen 17. The screened material falls into the first collection trough 25 below the screen 17, thus completing the entire screening process.
