Description

Technical Field

[0001] This utility model relates to the field of asphalt concrete technology, and in particular to a particle asphalt screening machine for asphalt concrete production. Background Technology

[0002] Traditional asphalt screening equipment requires manual removal of the screened granular asphalt, making it difficult to automatically discharge granular asphalt, thus reducing the screening efficiency of granular asphalt.

[0003] To address the aforementioned issues, existing patent publication number CN220759934U, entitled "A Granular Asphalt Screening Device for Asphalt Concrete Production," proposes a new invention. This invention utilizes a pusher plate, a sliding baffle, and a threaded shaft. The rotation of a second motor causes the threaded shaft to rotate, which in turn drives a transmission block to rotate a transmission rod. This causes the pusher plate to move a top rod to the right, pushing the screened granular asphalt to the right. The top rod also presses against the sliding baffle, creating a discharge port at the lower right side of the screening frame for the granular asphalt to be discharged. A granular output frame guides the granular asphalt for easy discharge.

[0004] However, the particle asphalt screening equipment for asphalt concrete production disclosed in the above patent needs to be stopped when the screened particle asphalt needs to be cleaned during use, which reduces the screening efficiency of particle asphalt. Therefore, it is necessary to propose a particle asphalt screening machine for asphalt concrete production to solve the above problem. Utility Model Content

[0005] The purpose of this utility model is to provide a granular asphalt screening machine for asphalt concrete production, in order to solve the problem mentioned in the background art that existing granular asphalt screening equipment for asphalt concrete production requires stopping the equipment when cleaning the screened granular asphalt, thereby reducing the screening efficiency of granular asphalt.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a granular asphalt screening machine for asphalt concrete production, comprising a base plate, a screening box being mounted on the top of the base plate via a connecting assembly, a vibrator being fixedly mounted on the top of the screening box, a hopper being fixedly mounted at one end of the top of the screening box, a motor being fixedly mounted at the end of the screening box, a spiral shaft being rotatably mounted inside the screening box, the output end of the motor being movably extended into the interior of the screening box and fixedly connected to the spiral shaft, an arc plate being mounted on the bottom of the interior of the screening box via a fixing assembly, the spiral shaft and the inner wall of the arc plate being in contact, a screen and a discharge port being fixedly mounted inside the arc plate, a flow collecting hood one being fixedly mounted at the bottom of the screen, a flow collecting hood two being fixedly mounted at the bottom of the discharge port, a conveyor belt one and a conveyor belt two being rotatably mounted on the top of the base plate, the conveyor belt one being located below the flow collecting hood one, and the conveyor belt two being located below the flow collecting hood two.

Four uprights are provided, and the four uprights are fixedly installed at the four corners of the top of the base plate. Four horizontal plates are provided, and the four horizontal plates are fixedly installed at the four corners of the side of the screening box. The horizontal plates and uprights correspond one-to-one in the vertical direction, and springs are fixedly connected between the horizontal plates and uprights.

[0008] Preferably, a rubber plate is fixedly provided at the bottom of the base plate.

[0009] Preferably, the fixing assembly includes two rows of mounting parts, which are respectively fixedly disposed at both ends of the arc plate. Each row of mounting parts includes three fixing blocks arranged at equal intervals. The fixing blocks are fixedly connected to the arc plate. The inner wall of the screening box is provided with a sliding groove for the fixing blocks to move through. The fixing blocks and the sliding groove are adapted to each other.

A screening box 5 is mounted on the top of the base plate 1 via a connecting assembly. A vibrator 6 is fixedly mounted on the top of the screening box 5. A hopper 7 is fixedly mounted at one end of the top of the screening box 5. A feed inlet communicating with the hopper 7 is opened on the top of the screening box 5. A motor 8 is fixedly mounted at the end of the screening box 5. A screw shaft 10 is rotatably mounted inside the screening box 5. The output end of the motor 8 extends movably into the interior of the screening box 5 and interacts with the screw shaft 10. 0. Fixed connection. The bottom of the screening box 5 is provided with an arc plate 9 by a fixed component. The spiral shaft 10 is attached to the inner wall of the arc plate 9. The screen 11 and the discharge port 12 are fixedly provided inside the arc plate 9. The bottom of the screen 11 is fixedly provided with a flow collecting hood 13. The bottom of the discharge port 12 is fixedly provided with a flow collecting hood 2 14. The top of the bottom plate 1 is rotatably provided with a conveyor belt 15 and a conveyor belt 2 16. The conveyor belt 15 is located below the flow collecting hood 13, and the conveyor belt 2 16 is located below the flow collecting hood 2 14.

[0024] The connecting components include uprights 2 and horizontal plates 3. There are four uprights 2, which are fixedly installed at the four corners of the top of the base plate 1. There are four horizontal plates 3, which are fixedly installed at the four corners of the side of the screening box 5. The horizontal plates 3 and the uprights 2 correspond one-to-one in the vertical direction. A spring 4 is fixedly connected between the horizontal plates 3 and the uprights 2.

[0025] Specifically, in the process of using this utility model, the material to be screened is fed into the screening box 5 through the hopper 7. The motor 8 is started, driving the spiral shaft 10 to rotate, causing the material to move at a uniform speed on the arc plate 9. At the same time, the vibrator 6 is started, and through the setting of four springs 4, the screening box 5 is vibrated. Asphalt particles that meet the particle size requirements fall into the inside of the first collection hood 13 through the screen 11 and are collected, and then fall onto the first conveyor belt 15 for conveying. Asphalt particles that do not meet the particle size requirements are pushed to the discharge port 12, fall into the inside of the second collection hood 14 and are collected, and then fall onto the second conveyor belt 16 for conveying. This achieves material screening and conveying without the need to stop the machine to process the screened granular asphalt. This solves the problem that existing granular asphalt screening equipment for asphalt concrete production requires stopping the equipment to clean the screened granular asphalt during use, thus reducing the screening efficiency of granular asphalt.

[0026] Furthermore, the fixing assembly includes two rows of mounting parts, which are respectively fixedly installed at both ends of the arc plate 9. Each row of mounting parts includes three equally spaced fixing blocks 17, which are fixedly connected to the arc plate 9.

The sliding groove 18 penetrates the lower surface of the screening box 5. The fixing blocks 17 and the screening box 5 are threadedly connected by bolts 19. When it is necessary to clean or replace the arc plate 9, the bolts 19 can be unscrewed to remove the arc plate 9 from the bottom of the screening box 5. After cleaning or replacing the arc plate 9, it can be installed in reverse, which improves the convenience of the device.

[0027] Furthermore, a rubber plate is fixedly installed at the bottom of the base plate 1 to reduce the vibration of the base plate 1.

[0028] Furthermore, the length of the screen 11 is greater than the length of the discharge port 12. This setting ensures that the material is fully screened.

[0029] Furthermore, a limiting post 20 is fixedly installed at the top of the column 2, and a limiting post 2 is fixedly installed at the bottom of the horizontal plate 3. There is a gap between the limiting post 20 and the limiting post 2. The spring 4 is movably sleeved on the outer ring of the limiting post 20 and the limiting post 2. The limiting post 2 is located directly above the limiting post 20. By setting the limiting post 20 and the limiting post 2, the spring 4 is limited, thereby ensuring the stable vibration of the screening box 5.

[0030] Working Principle: In use, the material to be screened is fed into the screening box 5 through the hopper 7. The motor 8 is started, driving the spiral shaft 10 to rotate, causing the material to move at a uniform speed on the arc plate 9. At the same time, the vibrator 6 is started, and through the setting of four springs 4, the screening box 5 vibrates. This causes the asphalt particles that meet the particle size requirements to fall into the inside of the first collection hood 13 through the screen 11 and then onto the first conveyor belt 15 for conveying. The asphalt particles that do not meet the particle size requirements are pushed to the discharge port 12, fall into the inside of the second collection hood 14 and then onto the second conveyor belt 16 for conveying. This achieves the screening and conveying of materials without stopping the machine to process the screened asphalt particles. When it is necessary to clean or replace the arc plate 9, the bolt 19 is unscrewed, and the arc plate 9 can be removed from the bottom of the screening box 5. After cleaning or replacing the arc plate 9, it can be installed in reverse.

[0031] The wiring diagrams of the vibrator 6 and motor 8 in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the vibrator 6 and motor 8 will not be explained in detail.
