Description

Technical Field

[0001] This invention relates to the field of cold patch asphalt production equipment technology, and more specifically, to a continuous cold patch asphalt production device and its usage method. Background Technology

[0002] Cold-patch asphalt mixture refers to a mixture formed by mixing unheated mineral aggregates with diluted asphalt. The strength formation process of cold-patch asphalt mixtures differs from that of hot-patch asphalt mixtures. Hot-patch asphalt mixtures use thermoplastic asphalt, while the asphalt in cold-patch asphalt mixtures is modified and is no longer completely thermoplastic.

[0003] Existing technologies disclose several patent documents related to asphalt cold patch material production equipment. Chinese patent application number CN202021882542.3 discloses a fully automatic asphalt cold patch material production equipment, relating to the field of asphalt cold patch material production and mixing technology. It includes four support legs and a mixing device. A support plate is fixedly connected to the middle of the four support legs, and the mixing device is mounted on the surface of the support legs. The mixing device includes a mixing drum, the surface of which is fixedly connected to the support legs. A rotating shaft is rotatably connected to the middle of the mixing drum, and four mixing blades are fixedly connected to the surface of the rotating shaft. The mixing blades are evenly distributed on the surface of the rotating shaft. A conical cylinder and a turntable are fitted onto the surface of the rotating shaft, and the surface of the turntable has fan-shaped grooves. This invention addresses the problem of uneven mixing of materials in asphalt cold patch material production due to insufficient mixing time. In some cases, materials poured in too quickly are not mixed evenly before being poured out, affecting the usability of the asphalt cold patch material. This device solves the problem of uneven mixing caused by inconsistent material pouring times during the mixing process.

[0004] In the aforementioned patent, the asphalt raw materials were not screened before mixing, resulting in poor mixing effect and inconsistent asphalt quality. To address this, we propose a continuous cold-mix asphalt production device and its usage method. Summary of the Invention

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the present invention aims to provide a continuous cold-mix asphalt production device and its usage method. In this invention, the rotation of the output end of the third rotary rod drives the second motor to rotate. The rotation of the second motor simultaneously drives the transmission gear and the rotary wheel to rotate. The rotation of the transmission gear drives the pusher plate to rotate. The rotation of the pusher plate facilitates the even feeding of asphalt raw materials into the second tank. Then, the intermittent movement of the rotary wheel, combined with the elasticity of the spring, causes the screening plate to reciprocate up and down. This reciprocating motion of the screening plate allows the asphalt raw materials on its surface to pass through the screening plate, thereby optimizing the stability of asphalt production quality.

[0018] In a preferred embodiment of the present invention, the driving assembly includes a support plate, a third rotating rod, a second motor, a transmission gear, and a rotating wheel. Two support plates are provided, both fixedly connected to a second cover plate. The third rotating rod is rotatably connected between the two support plates.

The output end of the second motor is fixedly connected to the support plate. The transmission gear and the rotating wheel are both fixedly connected to the surface of the third rotating rod, with the transmission gear located on the right side of the rotating wheel. The third rotating rod is located at the eccentric position of the rotating wheel.

[0019] In a preferred embodiment of the present invention, the pushing assembly includes a second rotating rod, a pushing plate, and a crown gear. The second rotating rod is rotatably connected to the third tank body, and the bottom of the second rotating rod moves through the third tank body.

[0024] A method for using a continuous cold-mix asphalt production device includes the following steps:

[0025] S1. First, the asphalt raw material is put into the third tank. Then, the output end of the second motor is started to rotate. The rotation of the output end of the second motor drives the third rotating rod to rotate. The rotation of the third rotating rod drives the transmission gear and the rotating wheel to rotate. The rotation of the transmission gear drives the crown gear to rotate. The rotation of the crown gear drives the second rotating rod to rotate. The rotation of the second rotating rod drives the two pusher plates to rotate. The rotation of the pusher plates causes the asphalt raw material in the third tank to be slowly put into the second tank through the second connecting pipe.

[0026] S2. When the asphalt raw material is fed into the second tank from the third tank, the asphalt will be fed onto the screening plate. At this time, the rotation of the third rotating rod can drive the rotating wheel to rotate. Since the third rotating rod is located at the eccentricity of the rotating wheel, the rotation of the rotating wheel will intermittently push the push plate to move downward. The downward movement of the push plate pushes the screening plate downward through the connecting rod. The movement of the screening plate causes the spring to be compressed. When the rotating wheel does not push the push plate to move, the screening plate pushes the screening plate to return to its original position through the elastic action of the spring. At this time, the intermittent movement of the rotating wheel combined with the elastic action of the spring causes the screening plate to move up and down. The up and down reciprocating movement of the screening plate causes the asphalt raw material on the surface of the screening plate to be screened through the screening plate and fall into the bottom of the second tank, and then fall into the first tank through the arc-shaped through hole and the first connecting pipe.

[0027] S3. After the sieved asphalt raw material falls into the first tank, the output end of the first motor can be started to rotate. The rotation of the output end of the first motor drives the first rotating rod to rotate. The rotation of the first rotating rod drives multiple stirring rods to rotate. The rotation of multiple stirring rods makes the asphalt raw material in the first tank mix and thus facilitates the production of cold patch asphalt.

[0028] 3. Beneficial effects

[0029] Compared with the prior art, the advantages of this invention are:

[0030] (1) The rotation of the output end of the third rotating rod in this scheme drives the second motor to rotate. The rotation of the second motor drives the transmission gear and the rotating wheel to rotate. The rotation of the transmission gear drives the pusher plate to rotate. The rotation of the pusher plate facilitates the even pushing of asphalt raw materials into the second tank. Then, the intermittent movement of the rotating wheel, combined with the elasticity of the spring, causes the screening plate to move up and down. The up and down reciprocating movement of the screening plate causes the asphalt raw materials on the surface of the screening plate to pass through the screening plate. When the asphalt raw materials after screening fall into the first tank, the output end of the first motor can be started to rotate. The rotation of the output end of the first motor drives the first rotating rod to rotate. The rotation of the first rotating rod drives multiple stirring rods to rotate. The rotation of multiple stirring rods makes the asphalt raw materials in the first tank mix and stir, which facilitates the production of cold patch asphalt and optimizes the stability of asphalt production quality.

[0031] (2) In this scheme, the discharge hole is opened to facilitate the discharge of materials that have not been screened from the surface of the screening plate. The sealing plug is used to block the discharge hole and is installed in the discharge hole by snap-fit. The arc-shaped through hole is used to facilitate the asphalt material to fall into the first connecting pipe. The first support rod is used to support the second tank.

The rotation of the pusher plate 17 facilitates the even pushing of the asphalt raw materials into the second tank 4. Then, the intermittent movement of the rotating wheel 23, combined with the elastic action of the spring 25, causes the screening plate 24 to move up and down reciprocally. The up and down reciprocating movement of the screening plate 24 causes the asphalt raw materials on the surface of the screening plate 24 to pass through the screening plate 24, thereby optimizing the stability of the asphalt production quality.

[0051] Specifically, the stirring mechanism includes a first motor 13, a first rotating rod 14, and a stirring rod 15. The first motor 13 is installed at the bottom of the first tank 1, and the output end of the first motor 13 moves through the first tank 1.

Multiple stirring rods 15 are provided, and multiple stirring rods 15 are fixedly connected to the surface of the first rotating rod 14.

[0052] In this embodiment, the output end of the first motor 13 is started to rotate. The rotation of the output end of the first motor 13 drives the first rotating rod 14 to rotate. The rotation of the first rotating rod 14 drives multiple stirring rods 15 to rotate. The rotation of the multiple stirring rods 15 makes the asphalt raw materials in the first tank 1 stir and mix, thereby facilitating the production of cold patch asphalt.

[0053] Specifically, the material selection mechanism includes a drive component, a push component, and a screening component. The drive component, push component, and screening component are all mounted on the second cover plate 5, and the drive component is connected to the push component and the screening component.

[0054] In this embodiment, the material selection mechanism includes a driving component, a pushing component, and a screening component. The driving component, the pushing component, and the screening component are all disposed on the second cover plate 5, and the driving component is connected to the pushing component and the screening component.

[0055] Specifically, the drive assembly includes a support plate 19, a third rotating rod 20, a second motor 21, a transmission gear 22, and a rotating wheel 23. There are two support plates 19, both of which are fixedly connected to the second cover plate 5. The third rotating rod 20 is rotatably connected between the two support plates 19. The second motor 21 is installed on the left side of the support plate 19, and the output end of the second motor 21 moves through the support plate 19. The output end of the second motor 21 is fixedly connected to the support plate 19. The transmission gear 22 and the rotating wheel 23 are both fixedly connected to the surface of the third rotating rod 20, with the transmission gear 22 located on the right side of the rotating wheel 23 and the third rotating rod 20 located at the eccentric position of the rotating wheel 23.

[0056] In this embodiment, the support plate 19 is for facilitating the rotational connection of the third rotating rod 20. The output end of the second motor 21 is started to rotate, and the rotation of the output end of the second motor 21 drives the third rotating rod 20 to rotate. The rotation of the third rotating rod 20 simultaneously drives the transmission gear 22 and the rotating wheel 23 to rotate.

[0057] Specifically, the feeding assembly includes a second rotating rod 16, a feeding plate 17, and a crown gear 18. The second rotating rod 16 is rotatably connected to the third tank 7, and the bottom of the second rotating rod 16 moves through the third tank 7. There are two feeding plates 17, and both feeding plates 17 are fixedly connected to the surface of the second rotating rod 16. The crown gear 18 is fixedly connected to the bottom of the second rotating rod 16, and the crown gear 18 meshes with the transmission gear 22.

[0058] In this embodiment, the rotation of the transmission gear 22 drives the crown gear 18 to rotate, which in turn drives the second rotating rod 16 to rotate. The rotation of the second rotating rod 16 then drives the two pusher plates 17 to rotate. The rotation of the pusher plates 17 causes the asphalt raw material in the third tank 7 to be slowly fed into the second tank 4 through the second connecting pipe 9.

[0059] Specifically, the screening assembly includes a screening plate 24, a spring 25, a limiting rod 26, a connecting ring 27, a connecting rod 28, and a push plate 29.

The connecting ring 27 is used to connect multiple limiting rods 26. The rotation of the rotating wheel 23 will intermittently push the push plate 29 to move downward. The downward movement of the push plate 29 pushes the screening plate 24 downward through the connecting rod 28. The movement of the screening plate 24 compresses the spring 25. When the rotating wheel 23 does not push the push plate 29 to move, the screening plate 24 is pushed upward to reset by the elastic action of the spring 25. At this time, the intermittent movement of the rotating wheel 23 combined with the elastic action of the spring 25 makes the screening plate 24 move up and down reciprocally. The up-and-down reciprocating movement of the screening plate 24 allows the asphalt raw material on the surface of the screening plate 24 to be screened through the screening plate 24.

[0061] Specifically, the surface of the second tank 4 is provided with a discharge hole 10, and a sealing plug 11 is detachably connected inside the discharge hole 10. The second tank 4 is provided with an arc-shaped through hole 12, which is connected to the first connecting pipe 8.

[0067] A method for using a continuous cold-mix asphalt production device includes the following steps:

[0068] S1. First, the asphalt raw material is put into the third tank 7. Then, the output end of the second motor 21 is started to rotate. The rotation of the output end of the second motor 21 drives the third rotating rod 20 to rotate. The rotation of the third rotating rod 20 simultaneously drives the transmission gear 22 and the rotating wheel 23 to rotate. The rotation of the transmission gear 22 drives the crown gear 18 to rotate. The rotation of the crown gear 18 drives the second rotating rod 16 to rotate. The rotation of the second rotating rod 16 drives the two pusher plates 17 to rotate. The rotation of the pusher plates 17 causes the asphalt raw material in the third tank 7 to be slowly put into the second tank 4 through the second connecting pipe 9.

[0069] S2. When the asphalt raw material is fed into the second tank 4 from the third tank 7, the asphalt raw material will be fed onto the screening plate 24. At this time, the rotation of the third rotating rod 20 can drive the rotating wheel 23 to rotate. Since the third rotating rod 20 is located at the eccentric position of the rotating wheel 23, the rotation of the rotating wheel 23 will intermittently push the push plate 29 to move downward. The downward movement of the push plate 29 pushes the screening plate 24 to move downward through the connecting rod 28. The movement of the screening plate 24 causes the spring 25 to be compressed. When the rotating wheel 23 does not push the push plate 29 to move, the screening plate 24 is pushed upward to reset by the elastic action of the spring 25. At this time, the intermittent movement of the rotating wheel 23 combined with the elastic action of the spring 25 causes the screening plate 24 to move up and down. The up and down reciprocating movement of the screening plate 24 causes the asphalt raw material on the surface of the screening plate 24 to be screened by the screening plate 24 and fall into the bottom of the second tank 4, and fall into the first tank 1 through the arc-shaped through hole 12 and the first connecting pipe 8.

[0070] S3. After the sieved asphalt raw material falls into the first tank 1, the output end of the first motor 13 can be started to rotate. The rotation of the output end of the first motor 13 drives the first rotating rod 14 to rotate. The rotation of the first rotating rod 14 drives multiple stirring rods 15 to rotate. The rotation of the multiple stirring rods 15 makes the asphalt raw material in the first tank 1 mixed, thus facilitating the production of cold patch asphalt.

A continuous cold-patch asphalt production device according to claim 5, characterized in that: The bottom of the first tank (1) is fixedly connected to a discharge pipe (30), and a valve (31) is installed on the surface of the discharge pipe (30). The bottom of the first tank (1) is fixedly connected to multiple support legs (32).

7. A method of using a continuous cold-mix asphalt production device, characterized in that, The continuous cold-mix asphalt production apparatus according to claim 6 includes the following steps: S1. First, put the asphalt raw material into the third tank (7), then start the output end of the second motor (21) to rotate. The rotation of the output end of the second motor (21) drives the third rotating rod (20) to rotate. The rotation of the third rotating rod (20) simultaneously drives the transmission gear (22) and the rotating wheel (23) to rotate. The rotation of the transmission gear (22) drives the crown gear (18) to rotate. The rotation of the crown gear (18) drives the second rotating rod (16) to rotate. The rotation of the second rotating rod (16) drives the two pusher plates (17) to rotate. The rotation of the pusher plates (17) causes the asphalt raw material in the third tank (7) to slowly enter the second tank (4) through the second connecting pipe (9). S2. When the asphalt raw material is fed from the third tank (7) into the second tank (4), the asphalt raw material will be fed onto the screening plate (24). At this time, the rotation of the third rotating rod (20) drives the rotating wheel (23) to rotate. Since the third rotating rod (20) is located at the eccentric part of the rotating wheel (23), the rotation of the rotating wheel (23) will intermittently push the push plate (29) downward. Through the downward movement of the push plate (29), the connecting rod (28) pushes the screening plate (24) downward. The movement of the screening plate (24) causes the spring (25) to be compressed. When the rotating wheel ( 23) When the push plate (29) is not pushed to move, the screening plate (24) is pushed upward to reset by the elastic action of the spring (25). At this time, the intermittent movement of the rotating wheel (23) combined with the elastic action of the spring (25) causes the screening plate (24) to move up and down. The up and down movement of the screening plate (24) causes the asphalt raw material on the surface of the screening plate (24) to be screened by the screening plate (24) and fall into the bottom of the second tank (4), and fall into the first tank (1) through the arc-shaped through hole (12) and the first connecting pipe (8). S3. When the sieved asphalt raw material falls into the first tank (1), the output end of the first motor (13) can be started to rotate. The rotation of the output end of the first motor (13) drives the first rotating rod (14) to rotate. The rotation of the first rotating rod (14) drives multiple stirring rods (15) to rotate. The rotation of multiple stirring rods (15) makes the asphalt raw material in the first tank (1) mix and thus facilitates the production of cold patch asphalt.
