Description

Technical Field

[0001] The present invention belongs to the technical field of asphalt concrete mixture production, and more specifically, particularly relates to an asphalt concrete production stirring mechanism and stirring method. Background Art

[0002] Asphalt concrete mixture is known for its good performance. When used as road paving, it can reduce the noise generated when cars are driving and ensure better grip when vehicles are driving on such roads. However, its production is relatively complicated and the asphalt and other mixtures used in it need to be heated.

[0003] 1. The traditional asphalt concrete production mixing method is to simply put the asphalt into the mixing barrel and stir it. This mixing method makes it difficult to fully mix the asphalt with stones, mineral powder, etc., resulting in inconsistent proportions of the components, affecting the quality and performance of the asphalt concrete, and may reduce the strength and durability of the asphalt concrete. Simple mixing may not ensure uniform temperature of the asphalt during the mixing process, and it is easy for local temperatures to be too high or too low, affecting the performance of the asphalt and the combination effect with other materials, and failing to achieve the ideal mixing effect. It may take a longer mixing time, reducing production efficiency.

[0004] 2. When the added asphalt concrete and other materials enter from a pipeline, there may be uneven feeding, which makes it difficult to achieve uniform distribution and affects the subsequent mixing effect and quality. It is easy to get clogged. If the asphalt concrete or other materials are sticky or have large particles, it will cause pipeline blockage and affect production continuity. The local impact force is large, which will cause a large impact on the local area of ​​the mixing device, causing equipment wear or even damage. It is difficult to accurately control the feed amount, which is not conducive to the precise control of the feed amount of different asphalt concretes, resulting in inaccurate proportions and affecting product performance. The mixing difficulty is increased. The uneven feeding method increases the difficulty of achieving uniform mixing of asphalt concrete during the mixing process, requiring longer mixing time and higher energy consumption.

[0005] 3. The traditional way of discharging is to remove the sleeve on the outside of the discharge pipe to allow the asphalt concrete to flow out from the inside of the discharge pipe. However, if it is not taken out in time, some of the asphalt concrete will spill out and cause waste. Moreover, when there is too much asphalt concrete inside, due to the gravity of the asphalt concrete, the asphalt concrete will be tightly pressed on the sleeve, causing the sleeve to be under greater pressure and making it difficult to remove the sleeve.

[0006] In view of this, the existing structure and defects are studied and improved, and an asphalt concrete production mixing mechanism and mixing method are provided. Summary of the invention

[0047] Working principle:

[0048] The first step is to start the second motor 18. The second motor 18 drives the third spiral 19 to rotate clockwise to put the asphalt into the first feed pipe 21. The third spiral 19 rotates clockwise to transfer the asphalt from the direction of the second motor 18 to the direction of the heating barrel 11. When the third spiral 19 transports the asphalt to the end of the first feed pipe 21, the asphalt will fall into the heating barrel 11. At this time, the third spiral 19 drives the first synchronous belt drive assembly 22 to drive clockwise, and the first synchronous belt drive assembly 22 drives the fourth spiral 23 to drive counterclockwise to put the mineral aggregate into the second feed pipe 24. The fourth spiral 23 rotates clockwise to bring the mineral aggregate into the heating barrel 11 to prevent the asphalt and the mineral aggregate from clogging the feed pipe.

[0049] The second step is to start the first motor 12, which drives the first spiral 13 to rotate clockwise, and the first spiral 13 drives the fan blade 14 to rotate clockwise. The fan blade 14 blows the hot air generated by the heating barrel 11 to the asphalt and mineral aggregate, and the fan blade 14 scrapes the top of the heating barrel 11 to clean the top of the heating barrel 11, and the first spiral 13 drives the second spiral 16 to rotate clockwise, and the second spiral 16 re-transmits the asphalt and mineral aggregate flowing into the discharge pipe 17 back to the heating barrel 11 to prevent the asphalt and mineral aggregate from flowing out of the heating barrel. 11, when discharging is required, the first motor 12 is controlled to rotate counterclockwise, the first motor 12 drives the first screw 13 to rotate counterclockwise, the first screw 13 drives the second screw 16 to rotate counterclockwise, when the first screw 13 rotates counterclockwise, the mixed asphalt concrete inside the heating barrel 11 is made to surge from top to bottom, speeding up the asphalt concrete from the heating barrel 11 to be transported out, and at the same time, the asphalt concrete is stirred to make the asphalt concrete mixed more evenly, and the counterclockwise rotation of the second screw 16 will also speed up the asphalt concrete from being transported out of the heating barrel 11.

[0050] In the third step, the first spiral 13 rotates continuously, and the side wall of the first spiral 13 will be wrapped by asphalt and mineral aggregate. The first spiral 13 will drive the asphalt and mineral aggregate to be transported from bottom to top, and the asphalt and mineral aggregate will surge from bottom to top inside the heating barrel 11. At this time, the third spiral 19 and the fourth spiral 23 rotate continuously clockwise, and the third spiral 19 and the fourth spiral 23 are also wrapped by asphalt and mineral aggregate. The third spiral 19 and the fourth spiral 23 transport the asphalt and mineral aggregate inside the heating barrel 11 from the direction of the second motor 18 to the heating barrel 11. At this time, the asphalt and mineral aggregate will surge in the horizontal direction. Due to the transmission of the third spiral 19 and the fourth spiral 23, the asphalt and mineral aggregate will not flow back from the first feed pipe 21 and the second feed pipe 24. The surge in the vertical and horizontal directions will make the asphalt and mineral aggregate mixed more evenly, reduce the mixing time, and improve the production efficiency.

[0051] The fourth step is to push the clamping block 29 from the middle to the left and right sides. At this time, the spring rod 28 will be forced to shrink. At this time, the collected barrel will be placed on top of the first sliding plate 26. When the collecting barrel is placed approximately at the center of the first sliding plate 26, the clamping block 29 is released. At this time, the spring rod 28 will extend, and the spring rod 28 drives the clamping block 29 to move from both sides to the middle, clamping the collecting barrel with the clamping block 29, and the clamping block 29 will also correct the position of the collecting barrel so that the collecting barrel is at the center of the first sliding plate 26.

[0052] The fifth step, at this time, the first sliding plate 26 is pushed toward the base 25, and the first sliding plate 26 drives the first rack 27, the spring rod 28, the clamping block 29 and the collecting bucket to move from front to back, and the first rack 27 is engaged with the gear 31, and the first rack 27 will drive the gear 31 to rotate counterclockwise, and the gear 31 drives the connecting rod 32 to rotate counterclockwise, and the connecting rod 32 drives the second synchronous belt drive assembly 33 to transmit counterclockwise, and the gear 31 drives the second rack plate 34 to move from front to back, and the second rack plate 34 will be separated from the bottom of the discharge pipe 17. At this time, the asphalt concrete inside the discharge pipe 17 falls into the collecting bucket.

At this time, the third screw (19) drives the first synchronous belt transmission component (22) to drive clockwise, and the first synchronous belt transmission component (22) drives the fourth screw (23) to drive counterclockwise, and the mineral aggregate is placed in the second feed pipe (24). The fourth screw (23) rotates clockwise to bring the mineral aggregate into the heating barrel (11), so as to prevent the asphalt and the mineral aggregate from clogging the feed pipe; S2, start the first motor (12), the first motor (12) drives the first spiral (13) to rotate clockwise, the first spiral (13) drives the fan blade (14) to rotate clockwise, the fan blade (14) blows the hot air generated by the heating barrel (11) toward the asphalt and mineral aggregate, and the fan blade (14) scrapes the top of the heating barrel (11) to clean the top of the heating barrel (11), and the first spiral (13) drives the second spiral (16) to rotate clockwise, the second spiral (16) transfers the asphalt and mineral aggregate flowing into the discharge pipe (17) back to the heating barrel (11) to prevent the asphalt and mineral aggregate from leaking. When the material needs to be discharged, the first motor (12) is controlled to rotate counterclockwise, the first motor (12) drives the first spiral (13) to rotate counterclockwise, the first spiral (13) drives the second spiral (16) to rotate counterclockwise, when the first spiral (13) rotates counterclockwise, the mixed asphalt concrete in the heating barrel (11) is caused to surge from top to bottom, accelerating the asphalt concrete to be transported out of the heating barrel (11) while stirring the asphalt concrete, so that the asphalt concrete is mixed more evenly, and the counterclockwise rotation of the second spiral (16) will also accelerate the asphalt concrete to be transported out of the heating barrel (11); S3, the first spiral (13) continues to rotate, the side wall of the first spiral (13) will be wrapped by asphalt and mineral aggregate, the first spiral (13) will drive the asphalt and mineral aggregate to be transported from bottom to top, the asphalt and mineral aggregate will surge from bottom to top inside the heating barrel (11), at this time, the third spiral (19) and the fourth spiral (23) continue to rotate clockwise, the third spiral (19) and the fourth spiral (23) are also wrapped by asphalt and mineral aggregate, the third spiral (19) and the fourth spiral (23) transport the asphalt and mineral aggregate inside the heating barrel (11) from the direction of the second motor (18) to the direction of the heating barrel (11), at this time the asphalt and mineral aggregate will surge in the horizontal direction; S4, the clamping block (29) is pushed from the middle to the left and right sides, and the spring rod (28) is forced to shrink. The collected bucket is placed above the first sliding plate (26). When the collection bucket is placed approximately at the center of the first sliding plate (26), the clamping block (29) is released. The spring rod (28) is stretched, and the spring rod (28) drives the clamping block (29) to move from both sides to the middle, and the clamping block (29) clamps the collection bucket. The clamping block (29) also corrects the position of the collection bucket so that the collection bucket is at the center of the first sliding plate (26); S5, at this time, the first sliding plate (26) is pushed toward the base (25), and the first sliding plate (26) drives the first rack (27), the spring rod (28), the clamping block (29) and the collecting bucket to move from front to back, and the first rack (27) is meshed with the gear (31), and the first rack (27) drives the gear (31) to rotate counterclockwise, and the gear (31) drives the connecting rod (32) to rotate counterclockwise, and the connecting rod (32) drives the second synchronous belt drive assembly (33) to transmit counterclockwise, and the gear (31) drives the second rack plate (34) to move from front to back, and the second rack plate (34) will be separated from the bottom of the discharge pipe (17), and the asphalt concrete inside the discharge pipe (17) falls into the collecting bucket.
