Description

Technical Field

[0001] This application relates to the field of asphalt concrete production technology, specifically to an asphalt concrete aggregate screening device. Background Technology

[0002] Vibrating screen is a core step in asphalt concrete production. Its core function is to achieve precise grading and quality control of heated aggregates. Through multiple layers of vibrating screens, aggregates are strictly separated according to standard particle size ranges to ensure that each aggregate range fully meets the gradation design requirements and provides a stable skeleton structure for the mixture.

[0003] However, in existing asphalt concrete aggregate screening devices, it has been found that traditional screening devices typically use an integrated spring vibration damping system, which easily leads to uneven amplitude in different parts, seriously affecting screening efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an asphalt concrete aggregate screening device that can absorb uneven vibrations through the damping properties of rubber and effectively absorb vibration differences between different sections through elastic buffer pads, thereby improving the uniformity of amplitude in all parts of the device, solving the problem of uneven amplitude in different parts of traditional devices, and improving the screening efficiency of the device. This solves the problem that traditional screening devices usually use an integral spring vibration damping system, which easily leads to uneven amplitude in different parts and seriously affects the screening efficiency.

[0005] To achieve the above objectives, this application provides the following technical solution: an asphalt concrete aggregate screening device, comprising a mounting plate and equidistantly arranged mounting blocks. The bottom surface of the mounting plate is fixedly connected to equidistantly arranged mounting rods. Each mounting rod has a guide rod slidably connected to its inner wall. Two of the guide rods have rigid springs fixedly installed on their upper surfaces, and the other two guide rods have rubber springs fixedly installed on their upper surfaces. The top ends of each rigid spring and rubber spring are fixedly installed to the bottom surface of the corresponding mounting rod. Below the mounting plate are equidistantly arranged support rods and equidistantly arranged... The square rods are provided, with the top end of each support rod fixedly connected to the bottom end of a corresponding guide rod, and the bottom end of each support rod fixedly connected to the upper surface of a corresponding mounting block. The bottom surfaces of the two guide rods are fixedly connected to the upper surface of the corresponding mounting blocks. Two connectors are fixedly connected to the front and back of each square rod, and two connectors are fixedly connected to the front and back of each mounting block. Each connector is fixedly connected to a corresponding connector with a bolt. Elastic buffer pads are provided between each end of each square rod and the corresponding mounting block.

[0006] To address the issue of uneven vibration amplitude in traditional screening devices using an integrated spring vibration damping system, and to prevent impact on screening efficiency, the above solution involves installing mounting rods on the bottom of the mounting plate. Guide rods are connected to these mounting rods, and rigid springs and rubber springs are connected to the corresponding mounting rods and guide rods, forming an independent spring assembly. Rubber springs replace some of the rigid springs, utilizing the damping properties of rubber to absorb uneven vibration. Simultaneously, the bottom end of the guide rod is connected to the corresponding mounting block and support rod, and the bottom end of the support rod is connected to the corresponding mounting block, thus installing the guide rod. A square rod is installed between two corresponding mounting blocks, connected to the mounting block via connector one, connector two, and bolts. An elastic buffer pad is placed between the square rod and the mounting block to effectively absorb vibration differences between sections, improving the uniformity of vibration amplitude across the device. This solution effectively solves the problem of uneven vibration amplitude in traditional screening devices using an integrated spring vibration damping system, thereby improving the screening efficiency of the device.

[0007] Furthermore, each of the mounting blocks is fixedly connected to a fastener on both its front and back sides.

[0008] The above method involves installing fasteners on the front and back of the mounting block to form a fixed connection. Through holes are opened on the surface of the fasteners, and the fasteners can be fixed to the ground by using mounting bolt assemblies, thereby fixing the mounting block in place.

[0009] Furthermore, a vibration motor is fixedly installed on the bottom surface of the mounting plate, and equidistant hoppers are fixedly installed on the upper surface of the mounting plate.

[0010] The above scheme involves installing a vibrating motor on the bottom surface of the mounting plate, which generates vibration force to enable the device to vibrate and screen. The feeding hopper is installed on the upper surface of the mounting plate, which facilitates the separate feeding of various aggregates after screening.

[0011] Furthermore, a filter cylinder is provided above the mounting plate, and the outer surface of the filter cylinder is fixedly connected with brackets arranged at equal intervals, with the bottom end of each bracket fixedly connected to the upper surface of the mounting plate.

[0012] The above solution involves placing a filter cartridge above the mounting plate, mounting a bracket on the surface of the filter cartridge, and connecting the bottom end of the bracket to the upper surface of the mounting plate to support the filter cartridge.

[0013] Furthermore, the bottom surface of the filter cylinder is rotatably equipped with equally spaced opening and closing doors, and the upper surface of the filter cylinder is fixedly connected to a feed pipe.

[0014] The above solution involves installing an opening and closing door on the bottom surface of the filter cylinder. The door has a built-in lock, which allows the door to open after the lock is released, thus allowing the aggregate inside the filter cylinder to fall out. The feed pipe is installed on the upper surface of the filter cylinder, making it easy to feed unscreened aggregate into the filter cylinder.

[0015] Furthermore, a baffle is fixedly connected to the inner wall of the filter cylinder, and a drive motor is fixedly connected to the right side of the filter cylinder.

[0016] The above solution involves installing a baffle on the inner wall of the filter cartridge to separate the finest aggregates. The drive motor is then installed on the right side of the filter cartridge and fixedly connected.

[0017] Furthermore, the output shaft of the drive motor is fixedly connected to a connecting rod, and the left end of the connecting rod is rotatably connected to the right side of the baffle.

[0018] The above scheme fixes the connecting rod to the output shaft of the drive motor, allowing the connecting rod to rotate via the drive motor. The left end of the connecting rod is rotatably connected to the right side of the baffle, and the surface of the connecting rod is also rotatably connected to the inner wall of the filter cartridge, making it easy for the drive motor to rotate the connecting rod.

[0019] Furthermore, filter plate one and filter plate two are fixedly installed on the outer surface of the connecting rod, and strip rods arranged at equal intervals are fixedly connected to the right side of both filter plate one and filter plate two.

[0020] The above scheme involves installing filter plate one and filter plate two on the surface of the connecting rod, fixing the connecting rod to filter plate one and filter plate two, so that filter plate one and filter plate two can rotate when the connecting rod rotates. A strip rod is installed on the right side of filter plate one and filter plate two. When filter plate one and filter plate two rotate, the strip rod can drive the aggregate to move, thereby screening the aggregate through filter plate one and filter plate two, so that the aggregate can be screened into coarse, fine and fine aggregate. Coarse aggregate is blocked by filter plate one, fine aggregate is blocked by filter plate two, and fine aggregate falls directly into the position of the baffle. Finally, the aggregate is discharged uniformly through the opening and closing gate.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This asphalt concrete aggregate screening device incorporates rigid springs, rubber springs, and elastic buffer pads. Rigid and rubber springs are installed between the guide rod and the mounting rod, with mounting blocks below forming independent spring groups. Square rods are positioned between the mounting blocks and connected by connectors one and two, and bolts. Elastic buffer pads are placed at the connection points. Rubber springs replace some of the rigid springs, utilizing the damping properties of rubber to absorb uneven vibrations. The elastic buffer pads effectively absorb vibration differences between sections, improving the uniformity of amplitude across the device. This device solves the problem of uneven amplitude caused by the integrated spring vibration damping system in traditional screening devices, thus improving screening efficiency. During screening, the drive motor rotates the connecting rod, which in turn rotates filter plates one and two, causing the strip rods to move the aggregate, forming a spiral screening process, thereby increasing screening efficiency and reducing clogging rate.

The feed pipe 17 is set on the upper surface of the filter cylinder 16, and the unscreened aggregate can be easily fed into the filter cylinder 16 through the feed pipe 17.

[0038] Please see Figure 4 and Figure 5 A baffle 23 is fixedly connected to the inner wall of the filter cylinder 16, and a drive motor 19 is fixedly connected to the right side of the filter cylinder 16. The baffle 23 is installed on the inner wall of the filter cylinder 16 to separate the finest aggregate.

The left end of the connecting rod 20 is rotatably connected to the right side of the baffle 23, thus fixing the connecting rod 20 to the output shaft of the drive motor 19. The drive motor 19 enables the connecting rod 20 to rotate. The left end of the connecting rod 20 is rotatably connected to the right side of the baffle 23, and the surface of the connecting rod 20 is also rotatably connected to the inner wall of the filter cartridge 16, so that the drive motor 19 can drive the connecting rod 20 to rotate.

[0040] Please see Figure 4 and Figure 5A filter plate 21 and a filter plate 22 are fixedly installed on the outer surface of the connecting rod 20.

The filter plate 21 and the filter plate 22 are installed on the surface of the connecting rod 20, and the connecting rod 20 is fixed to the filter plate 21 and the filter plate 22 so that the filter plate 21 and the filter plate 22 can rotate when the connecting rod 20 rotates. The strip rods 24 are installed on the right side of the filter plate 21 and the filter plate 22. When the filter plate 21 and the filter plate 22 rotate, the strip rods 24 can drive the aggregate to move, thereby screening the aggregate through the filter plate 21 and the filter plate 22, allowing the aggregate to be screened into coarse, fine, and fine aggregates.

[0041] This embodiment of an asphalt concrete aggregate screening device incorporates components such as rigid springs 4, rubber springs 5, and elastic buffer pads 12. Rigid springs 4 and 5 are positioned between guide rods 3 and mounting rods 2, with mounting blocks 6 below, forming an independent spring assembly. Square rods 9 are positioned between mounting blocks 6 and connected via connectors 10, 8, and bolts 11. Elastic buffer pads 12 are placed at the connection points. Rubber springs 5 ​​replace some of the rigid springs 4, utilizing the damping properties of rubber to absorb uneven vibrations. The elastic buffer pads 12 effectively absorb vibration differences between segments, improving the uniformity of amplitude across the device. This device solves the problem of uneven amplitude caused by the integrated spring vibration damping system in traditional screening devices, thus improving screening efficiency. During screening, the drive motor 19 is activated, causing the connecting rod 20 to rotate. The connecting rod 20 drives the filter plates 21 and 22 to rotate, allowing the strip rod 24 to move the aggregate, forming a spiral screening process, thereby increasing screening efficiency and reducing clogging rate.

[0042] It should be noted that the drive motor 19 is a servo motor, which enables the connecting rod 20 to rotate, thereby enabling the first filter plate 21 and the second filter plate 22 to rotate.

[0043] The working principle of the above embodiments is as follows:

[0044] A mounting rod 2 is installed on the bottom surface of the mounting plate 1. A rigid spring 4 and a rubber spring 5 are installed between the guide rod 3 and the mounting rod 2. A support rod 7 and a mounting block 6 are installed to support the guide rod 3, forming an independent spring group. A square rod 9 is installed between the mounting blocks 6 and connected by connector 10, connector 2 8 and bolt 11. An elastic buffer pad 12 is installed between the mounting blocks 6 and the square rod 9. The rubber spring 5 replaces part of the rigid spring 4, utilizing the damping characteristics of rubber to absorb uneven vibration. The elastic buffer pad 12 effectively absorbs the vibration differences between different sections, improving the amplitude consistency of each part of the device. This device can solve the problem of amplitude variation caused by the integrated spring vibration reduction system in traditional screening devices. Unevenness occurs, so the screening efficiency of the device is improved. The aggregate is fed into the filter cylinder 16 through the feed pipe 17. The vibration motor 14 is started to make the filter cylinder 16 and other components vibrate to achieve screening. During screening, the drive motor 19 is started to make the connecting rod 20 rotate. The connecting rod 20 drives the first filter plate 21 and the second filter plate 22 to rotate, so that the strip rod 24 can drive the aggregate to move, forming a spiral screening, which improves the screening efficiency and reduces the clogging rate. After screening, the coarse aggregate is blocked by the first filter plate 21, the fine aggregate is blocked by the second filter plate 22, and the fine aggregate falls directly to the position of the baffle 23. Finally, the opening and closing door 25 is opened so that the corresponding aggregate can fall into the corresponding feed hopper 15 for feeding.
