Description

Technical Field

[0001] This utility model relates to the field of sand and gravel processing technology, specifically to a sand and gravel screening device that integrates crushing and screening. Background Technology

[0002] Sand and gravel refer to a loose mixture of sand and gravel. In geology, mineral or rock particles with a diameter of 0.074 to 2 mm are called sand. During sand and gravel processing, they need to be crushed and screened through a hexagonal sieve.

[0003] Existing screening devices work by feeding sand and gravel into a hexagonal screen body, which then rotates to crush and screen the sand and gravel.

[0004] However, when existing screening devices are in operation, the tilt angle of the hexagonal screen body is fixed and cannot be adjusted. This results in the sand and gravel rolling at a uniform speed. If the sand and gravel with high viscosity are being screened, the crushing and screening time for different types of sand and gravel may be relatively long, which may lead to incomplete screening of different types of sand and gravel, thus reducing the applicability of existing screening devices. Utility Model Content

This solves the problem that existing screening devices, due to the inability to adjust the angle of the hexagonal screen body, are prone to incomplete screening of different types of sand and gravel when screening sand and gravel with high viscosity, thus reducing the applicability of existing screening devices.

[0007] Preferably, the auxiliary unit includes: a bevel gear set fixedly connected to the outer wall of the stud away from the threaded block; a screw fixedly connected to the top of the bevel gear set; a column threadedly connected to the outer wall of the screw, penetrating the housing and movably connected to the housing; and a connecting plate fitted to the top of the column, with its end fixedly connected to the outer wall of the housing; wherein, driven by the stud, the bevel gear set causes the screw to move the column, thereby ensuring that the column remains in contact with the connecting plate.

[0008] Preferably, a horizontal column is fixedly connected to the inner wall of the housing, and the inner wall of the horizontal column is rotatably connected to the outer wall of the screw through a bearing.

[0012] Preferably, rollers are installed on the inner walls of the outer shell and the cover, a baffle is installed on the inner wall of the outer shell away from the rollers, and a dust removal pipe is connected to the inner wall of the cover.

[0013] Beneficial effects

[0014] This utility model provides an integrated crushing and screening sand and gravel screening device. It has the following advantages: This integrated crushing and screening sand and gravel screening device, through the cooperation of a first motor, stud, threaded block, inclined column, vertical block, and support column, achieves adjustment of the inclination angle of the hexagonal screen body. This solves the problem that existing screening devices, due to the inability to adjust the angle of the hexagonal screen body, often result in incomplete screening of different types of sand and gravel, especially when screening highly viscous sand and gravel, thus reducing the applicability of existing screening devices.

[0021] 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.

[0022] Existing screening devices, due to the inability to adjust the angle of the hexagonal screen body, are prone to incomplete screening of different types of sand and gravel when screening sand and gravel with high viscosity, thus reducing the applicability of existing screening devices.

[0023] In view of this, the present invention provides an integrated crushing and screening sand and gravel screening device. Through the cooperation between the first motor, stud, threaded block, inclined column, vertical block and support column, the tilt angle of the hexagonal screen body can be adjusted. This solves the problem that existing screening devices cannot adjust the angle of the hexagonal screen body, which can easily lead to incomplete screening of different types of sand and gravel when screening sand and gravel with high viscosity, thus reducing the applicability of existing screening devices.

[0024] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly introduced below.

[0025] Example 1, by Figure 1-4As can be seen, the integrated crushing and screening sand and gravel screening device in this case includes a shell 3. The shell 3 and the cover 4 can prevent sand and gravel from splashing to the outside during screening. A hexagonal screen body 5 is installed inside the shell 3. Sand and gravel are fed into the hexagonal screen body 5, which rotates, thus driving the sand and gravel to rotate. This crushes and screens the sand and gravel, separating out hard particles larger than 10mm. The screen mesh inside the hexagonal screen body 5 is fixed by tension and compression, resulting in a taut mesh that is not easily damaged and has a rebound crushing effect. The screen mesh is a 12×18 long-hole mesh made of cold-drawn stainless steel high-strength coarse wire woven mesh, with a long service life. The screen area is equivalent to an increase of 30-40%, and the rotation speed is close to the theoretical rotation speed. The screen plunges from near its highest point into the sieve cylinder, achieving both crushing and fine screening with minimal mesh clogging. It removes hard particles larger than 10mm from the old sand, resulting in uniform molding sand quality. A cover 4 is hinged to the top of the outer shell 3, allowing operators to open it for screen replacement or cleaning and maintenance of the hexagonal screen body 5. A mounting plate 1 is located below the outer shell 3, with four mounting holes distributed on both sides. Operators use these holes to install the entire screening device onto the external base. A box 6, L-shaped, is fixedly connected to the surface of the mounting plate 1. An adjustment mechanism 2 is located inside the box 6, including a first motor 21 (model selected according to actual needs) to meet operational requirements. The system is as follows: First motor 21 is bolted to the outer wall of housing 6. When screening sand and gravel of different viscosities, first motor 21 is connected to an external power source. Stud 22 is rotatably connected to the inner wall of housing 6 at both ends via bearings. First motor 21 drives stud 22 to rotate, and its end is fixedly connected to the output shaft of first motor 21. Threaded block 23 is threaded to the outer wall of stud 22. Stud 22 drives threaded block 23 to move, and its bottom slides against the inner wall of mounting plate 1. Threaded block 23 slides in a limiting groove on the surface of mounting plate 1, limiting its movement. Inclined column 24 is rotatably connected to the inner wall of threaded block 23 via a pin. Threaded block 23 drives inclined column 24 to rotate. Vertical block 25 is rotatably connected via a pin. At the end of the inclined column 24 furthest from the threaded block 23, the inclined column 24 drives the vertical block 25 to move, and its top is fixedly connected to the outer wall of the outer casing 3. The vertical block 25 drives the outer casing 3 to rotate. There are two support columns 26, both fixedly connected to the surface of the mounting plate 1 on the side furthest from the housing 6, and their tops are rotatably connected to the outer wall of the outer casing 3 via pins. The outer casing 3 rotates around the pins on the support columns 26, driving the hexagonal screen body 5 to rotate and adjusting the tilt angle of the hexagonal screen body 5. The auxiliary unit 27 is located inside the housing 6. Under the drive of the first motor 21, the stud 22 causes the threaded block 23 to drive the inclined column 24 to rotate, thereby causing the vertical block 25 to drive the outer casing 3 to rotate around the pins on the support columns 26.This causes the hexagonal sieve body 5 to rotate, and the auxiliary unit 27 further supports the outer shell 3;

[0026] In the specific implementation process, it is worth noting that the first motor model 21 is selected according to actual needs, as long as it meets the operational requirements. The outer shell 3 and the shell cover 4 can prevent sand and gravel from splashing to the outside during screening. The sand and gravel are put into the hexagonal screen body 5, and the hexagonal screen body 5 rotates, thereby driving the sand and gravel to rotate. This can crush the sand and gravel, and at the same time, it can screen out the hard particles larger than 10mm inside the sand and gravel. The screen mesh inside the hexagonal screen body 5 is fixed by tension and compression, the mesh surface is taut and not easy to break, and it also has a rebound crushing effect. The screen mesh is a 12×18 long hole mesh, and the material is... Made of cold-drawn stainless steel high-strength coarse wire woven mesh, it has a long service life and increases the screen area by 30-40%. At near-theoretical rotation speed, material flows down from near the highest point of the screen cylinder, achieving crushing and fine screening with minimal mesh clogging. It removes hard particles larger than 10mm from old sand, resulting in uniform molding sand quality. Workers can open the cover 4 to replace the screen or clean and repair the hexagonal screen body 5. The mounting plate 1 has four mounting holes distributed on both sides. Workers install the entire screening device onto the external base through these holes. When screening sand and gravel of different viscosities, the first motor 21 is connected to an external power supply. The first motor 21 drives the stud 22 to rotate, the stud 22 drives the threaded block 23 to move, the threaded block 23 slides in the limiting groove on the surface of the mounting plate 1 to limit the threaded block 23, the threaded block 23 drives the inclined column 24 to rotate, the inclined column 24 drives the vertical block 25 to move, the vertical block 25 drives the outer shell 3 to rotate, the outer shell 3 rotates around the pin on the support column 26 as the center, the outer shell 3 drives the hexagonal screen body 5 to rotate, and the tilt angle of the hexagonal screen body 5 is adjusted. After the adjustment is completed, the first motor 21 is stopped, thus realizing the adjustment of the tilt angle of the hexagonal screen body 5.

[0027] Furthermore, the auxiliary unit 27 includes: a bevel gear set 271, fixedly connected to the outer wall of the stud 22 away from the threaded block 23. When adjusting the tilt angle of the hexagonal screen body 5, the stud 22 drives the bevel gear set 271 to rotate. The bevel gear set 271 includes a first bevel gear and a second bevel gear. The first bevel gear is fixedly connected to the outer wall of the stud 22, and the second bevel gear is meshed above the first bevel gear. The second bevel gear is fixedly connected to the bottom of the screw 272. The screw 272 is fixedly connected to the top of the bevel gear set 271. The bevel gear set 271 drives the screw 272 to rotate. A column 273 is threadedly connected to the outer wall of the screw 272. The screw 272 drives the column 273 to move and penetrates the housing 6. The column 273 is movably connected to the housing 6 and moves within the housing 6. The column 273 is square in shape and has a circular protrusion on the top. The connecting plate 274 is attached to the top of the column 273 and its end is fixedly connected to the outer wall of the housing 3. When the housing 3 rotates, the housing 3 drives the connecting plate 274 to move. The column 273 is always in contact with the surface of the connecting plate 274. When the stud 22 stops rotating, the column 273 also stops moving. When the stud 22 rotates in the opposite direction, the column 273 descends back to its initial position. The bevel gear set 271, driven by the stud 22, causes the screw 272 to drive the column 273 to move, so that the column 273 is always in contact with the connecting plate 274.

[0028] In the specific implementation process, it is worth noting that when adjusting the tilt angle of the hexagonal screen body 5, the stud 22 drives the bevel gear set 271 to rotate. The bevel gear set 271 includes a first bevel gear and a second bevel gear. The first bevel gear is fixedly connected to the outer wall of the stud 22, and the second bevel gear is meshed above the first bevel gear. The second bevel gear is fixedly connected to the bottom of the screw 272. The bevel gear set 271 drives the screw 272 to rotate, and the screw 272 drives the column 273 to move. The column 273 moves within the housing 6, limiting its position. The column 273 is square in shape with a circular protrusion at the top. When the outer shell 3 rotates, it drives the connecting plate 274 to move. The column 273 remains in contact with the surface of the connecting plate 274. When the stud 22 stops rotating, the column 273 also stops moving. When the stud 22 rotates in the opposite direction, the column 273 descends back to its initial position, further supporting the outer shell 3 and reducing the load on the inclined column 24.

[0029] Furthermore, a horizontal column 2721 is fixedly connected to the inner wall of the housing 6. The inner wall of the horizontal column 2721 is rotatably connected to the outer wall of the screw 272 through a bearing. The horizontal column 2721 supports the screw 272, making the rotation of the screw 272 stable.

[0030] In the specific implementation process, it is worth noting that the horizontal column 2721 supports the screw 272, so that the rotation of the screw 272 is stable;

[0031] Specifically, when screening sand and gravel of different viscosities, the first motor 21 is first connected to an external power source. The first motor 21 drives the stud 22 to rotate, which in turn drives the threaded block 23 to move. Simultaneously, the stud 22 drives the bevel gear set 271 to rotate, which in turn drives the screw 272 to rotate. The screw 272 then drives the column 273 to move, which moves within the housing 6. The threaded block 23 slides in the limiting groove on the surface of the mounting plate 1. The threaded block 23 drives the inclined column 24 to rotate, which in turn drives the vertical block 25 to move. Block 25 drives the outer casing 3 to rotate. The outer casing 3 rotates around the pin on the support column 26. The outer casing 3 drives the connecting plate 274 to move. The column 273 is always in contact with the surface of the connecting plate 274. The outer casing 3 drives the hexagonal screen body 5 to rotate. The tilt angle of the hexagonal screen body 5 is adjusted. After the adjustment is completed, the first motor 21 is stopped. Then the staff puts the sand and gravel into the hexagonal screen body 5. The hexagonal screen body 5 rotates, thereby driving the sand and gravel to rotate. This can crush the sand and gravel and also screen it.

[0032] Example 2, by Figure 1-4 It can be seen that a reduction gearbox 58 is installed on the side of the outer shell 3 away from the connecting plate 274. The output shaft of the reduction gearbox 58 is rotatably connected to the inner wall of the outer shell 3 through a bearing. The output shaft of the reduction gearbox 58 is fixedly connected to one side of the hexagonal screen body 5. The reduction gearbox 58 drives the hexagonal screen body 5 to rotate. When the sand and gravel screening is completed, the second motor 57 is stopped. The second motor 57 is fixedly connected to the bottom of the reduction gearbox 58. The second motor 57 is connected to an external power supply. The second motor 57 drives the reduction gearbox 58 to rotate. The second motor 57 is fixedly connected to the side of the outer shell 3 away from the connecting plate 274 through a motor sleeve. The model of the second motor 57 is selected according to actual needs, as long as it meets the working requirements.

[0033] In the specific implementation process, it is worth noting that the model of the second motor 57 is selected according to actual needs, as long as it meets the working requirements. The second motor 57 is connected to an external power supply, and the second motor 57 drives the reduction gearbox 58 to rotate. The reduction gearbox 58 drives the hexagonal screen body 5 to rotate. When the sand and gravel screening is completed, the second motor 57 is stopped, thus driving the hexagonal screen body 5 to rotate.

[0034] Furthermore, a feed pipe 51 is fixedly connected to the side of the outer shell 3 near the connecting plate 274. The sand and gravel material should be magnetically separated and then evenly fed into the screen body to extend the service life of the screen. The staff puts the sand and gravel into the feed pipe 51, and the sand and gravel fall into the hexagonal screen body 5 along the feed pipe 51. The feed pipe 51 extends into the interior of the hexagonal screen body 5. A vibration motor 511 is installed on the outer wall of the feed pipe 51. At the same time, the vibration motor 511 is started to make the feed pipe 51 vibrate, so as to prevent the inside of the feed pipe 51 from being blocked. The model of the vibration motor 511 is selected according to the actual needs, as long as it meets the working requirements.

At the same time, the vibration motor 511 is started to make the feed pipe 51 vibrate, so as to prevent the inside of the feed pipe 51 from becoming blocked.

[0036] Furthermore, a slag outlet 52 is provided on the side of the hexagonal screen body 5 near the gearbox 58. When the hexagonal screen body 5 screens the sand and gravel, hard particles larger than 10mm move along the hexagonal screen body 5 to its bottom and are discharged into the interior of the outer shell 3 through the slag outlet 52, and then discharged into the interior of the outer shell 3 through the slag outlet 53. The bottom of the outer shell 3 is provided with a slag outlet 53 and a discharge outlet 54 respectively.

The screened sand and gravel fall into the outer shell 3 through the internal screen mesh holes of the hexagonal screen body 5 and are discharged from the outer shell 3 through the discharge outlet 54, thus realizing the discharge of sand and gravel.

[0038] Furthermore, rollers 56 are respectively installed on the inner walls of the outer shell 3 and the cover 4. When the hexagonal screen body 5 rotates, there are two rollers 56. The outer walls of the rollers 56 are in contact with the outer walls of the hexagonal screen body 5. The rollers 56 rotate on the left end of the hexagonal screen body 5 to stabilize the rotation of the hexagonal screen body 5.
