Description

Technical Field

[0001] The present invention relates to the technical field of conveying devices, and more specifically, to a conveying device for reclaimed asphalt concrete old materials. Background Art

[0002] The utilization of reclaimed asphalt pavement (RAP) is an important link in the road construction industry. It not only helps to reduce the demand for new materials, lower construction costs, but also effectively reduces the impact on the environment.

[0003] In the plant-mixed hot recycling technology, by heating the RAP (old asphalt concrete material) to an appropriate temperature and adding new asphalt and recycling agent for thorough stirring and mixing, its good working performance can be restored, thus realizing the effective recycling and resource utilization of the old materials. However, in the conveying process of the heated and mixed RAP, there are still certain limitations in the existing technology.

[0004] Most of the currently adopted conveying devices only have the basic function of material conveying, lacking the ability to perform secondary uniform mixing of the recycled mixture during the conveying process, and it is difficult to further improve the homogeneity of the materials and the construction quality. In addition, due to the certain adhesiveness of the recycled materials, especially at high temperatures, it is extremely easy to adhere to the surface of the conveyor belt. As the operation time prolongs, the material layer continuously thickens, which not only increases the running resistance of the equipment, but also may cause problems such as unsmooth discharging and material blockage, thus affecting the continuity and efficiency of the entire recycling production process.

[0005] Therefore, the existing conveying devices still need to be optimized and improved in terms of functional integration, process adaptability and operation stability.

[0006] Based on this, the present invention discloses a conveying device for reclaimed asphalt concrete old materials. Summary of the Invention

[0007] To solve the problems raised in the background art that in the plant-mixed hot recycling process, although the performance of RAP can be restored by heating and adding new asphalt and recycling agent, the existing conveying devices can only complete the material transfer and lack the function of further mixing evenly during the conveying process. In addition, the adhesiveness of the recycled materials causes them to easily adhere and accumulate on the conveyor belt, affecting the smoothness of discharging and production efficiency, showing deficiencies in functional integration and process adaptability, the present invention provides a conveying device for reclaimed asphalt concrete old materials, which includes a bracket and a mounting plate arranged on the bracket. A transmission rod driven by a corresponding motor is arranged between the mounting plates, and a conveyor belt is arranged on the transmission rod.

[0008] In order to realize the reuse of power through this conveying process, and at the same time, during the conveying process of the conveyor belt, an effect similar to a container is formed on the conveyor belt;

[0009] As a further improvement of this technical solution, a chain is also provided on the transmission rod, and baffles are provided on the mounting plate on both sides of the conveyor belt.

[0010] During the traditional process of conveying old materials, since the old materials need to go through processes such as mixing and heating, if there are some uneven mixing phenomena during the conveying stage, it will affect the subsequent laying; secondly, during the conveying process of the old materials, the old materials are easily adhered to the surface of the conveyor belt, resulting in a discount in conveying efficiency; this technical solution adopts a number of conveying units arranged along the conveying direction of the conveyor belt on the mounting plate for stirring and scraping the old materials on the conveyor belt.

[0011] As a further improvement of this technical solution, the conveying unit includes a swinging assembly and a first pushing assembly. The swinging assembly includes a number of drainage plates that can swing left and right. The bottom of the conveying drainage plate is attached to the surface of the conveyor belt. The swinging assembly also includes a first support rod fixed on the mounting plate. The first support rod extends directly above the conveyor belt, and the length of the first support rod is adapted to the width of the conveyor belt; a number of mounting rods are evenly fixed on the first support rod along the width direction of the conveyor belt. A rotating sleeve is rotatably connected to the mounting rod, and the drainage plate is fixed on the rotating sleeve; it should be added that the bottom of the drainage plate is provided with a high-temperature resistant and soft material.

[0012] On this basis, since the old materials themselves have a certain viscosity, and the drainage plates are required to stir and mix them, it is necessary to increase the flow rate of the old materials on the conveyor belt; moreover, the swinging of the drainage plates requires a periodic reciprocating force to drive them;

[0013] As a further improvement of this technical solution, the first pushing assembly includes a first rotating rod rotatably provided on the mounting plate and a first driving gear driven by a chain. The first driving gear is arranged on the first rotating rod. The first driving gear meshes with the chain. The first rotating rod is located above the baffle; at the same time, a reciprocating structure is provided on the first rotating rod, and a number of drainage plates are reciprocally swung through the reciprocating structure; a number of first rotating plates are arranged on the first rotating rod at the discharge end of the drainage plate. A first scraping plate is fixed at the end of the first rotating plate. The first scraping plate is made of a high-temperature resistant and soft material.

[0014] As a further improvement of the technical solution, the reciprocating structure includes a reciprocating lead screw fixed on the first rotating rod. The reciprocating lead screw is located on the side of the baffle away from the conveyor belt. A reciprocating plate is engaged with the reciprocating lead screw. A limiting rod is fixed on the side of the reciprocating plate away from the baffle. The limiting rod is slidably connected to the mounting plate. A second support rod is fixed on the reciprocating plate. The second support rod extends directly above the conveyor belt. A plurality of connecting rods corresponding to the diversion plate are fixed on the second support rod. A chute is formed on the connecting rod. A sliding rod is slidably connected in the chute. The sliding rod is fixed on the end of the diversion plate away from the rotation connection; and the limiting rod is adapted to the threaded area of the reciprocating lead screw.

[0015] In another solution, since the initial velocity of the old material after heating and mixing is not enough when it enters the feeding end of the conveyor belt, it is not conducive to the old material directly entering the first conveying unit. That is to say, the old material cannot form a rapid flow in the diversion channel formed by the first group of diversion plates.

[0016] As a further improvement of the technical solution, a second pushing component is arranged on the mounting plate at the feeding end of the conveyor belt. The second pushing component is used to accelerate the initial velocity of the old material entering the conveyor belt. The second pushing component includes a second rotating rod rotatably arranged on the mounting plate. A second driving gear is fixed on the second rotating rod above the chain. The second driving gear is engaged with the chain. A plurality of second rotating plates are circumferentially fixed on the second rotating rod between the two baffles. A second scraping plate is fixed on the end of the second rotating plate away from the second rotating rod. The second scraping plate is attached to the surface of the conveyor belt. The second scraping plate is also made of high-temperature resistant and soft materials.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In this regenerated asphalt concrete old material conveying device, the diversion plate of the swinging component is attached to the surface of the conveyor belt, and a dynamically changing diversion channel is formed during the left and right swinging process. At the same time, the flexible material scrapes off the adhered old material. The swinging of the diversion plate forms a dynamic diversion channel, continuously changing the flow path of the old material, enhancing the mixing uniformity; at the same time, the bottom of the diversion plate is attached to the surface of the conveyor belt, which can effectively prevent the old material from adhering and accumulating; it solves the problem that the regenerated material is easy to adhere due to strong adhesiveness, and improves the fluidity and mixing uniformity during the conveying process.

[0019] 2. In this recycled asphalt concrete old material conveying device, the "water wheel effect" of the first rotating plate and the first scraping plate is used to accelerate and initially stir the old material; the first rotating rod drives the first rotating plate to rotate, and the first scraping plate is close to the surface of the conveyor belt, pushing the old material forward and accelerating it. On the one hand, it provides sufficient material flow speed support for the mixing function of the diversion plate, and on the other hand, it realizes the initial stirring and dispersion of the old material through the rotating action, improving the overall mixing efficiency.

[0020] 3. In this recycled asphalt concrete old material conveying device, the second pushing component is used to increase the initial speed of the old material when it enters the conveyor belt. The second rotating rod is driven by a chain to drive the second rotating plate and the second scraping plate to rotate, applying a thrust to the old material at the feeding end; it solves the problem that the old material is difficult to enter the diversion channel due to insufficient initial speed, enabling the material to quickly enter the diversion area between the diversion plates and avoiding blockage and retention phenomena.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] During the in-plant hot recycling process, although heating and adding new asphalt and recycling agents can restore the performance of RAP, the existing conveying devices can only complete the material transfer and lack the function of further mixing evenly during the conveying process. In addition, the adhesion of the recycled materials causes them to easily adhere and accumulate on the conveyor belt, affecting the smoothness of the discharge and the production efficiency, showing deficiencies in functional integration and process adaptation.

[0039] Therefore, the present invention provides a conveying device for recycled asphalt concrete old materials. Refer to Figures 1 - 2 As shown, it includes a bracket 1 and a mounting plate 2 provided on the bracket 1. A transmission rod 4 driven by a corresponding motor is provided between the mounting plates 2, and a conveyor belt 9 is provided on the transmission rod 4.

[0040] During operation, the transmission rod 4 is driven to rotate by a corresponding motor, and then the entire conveyor belt 9 is driven to achieve conveying. In order to realize the reuse of power during this conveying process and form an approximate container effect on the conveyor belt 9 during the conveying process of the conveyor belt 9, so as to facilitate subsequent stirring and other effects of the old materials in this container, therefore, a chain 5 is also provided on the transmission rod 4, and baffles 10 are provided on both sides of the conveyor belt 9 on the mounting plate 2.

[0041] Specifically, refer to Figures 2 - 7As shown, during the process of conveying old materials, since the old materials need to go through processes such as mixing and heating, if there are some uneven mixing phenomena during the conveying stage, it will affect the subsequent laying. Secondly, during the conveying process of the old materials, the old materials are prone to sticking to the surface of the conveyor belt 9, resulting in a reduction in conveying efficiency and affecting future use. Therefore, in the present invention, a number of conveying units for stirring and scraping the old materials on the conveyor belt 9 are arranged on the mounting plate 2 along the conveying direction of the conveyor belt 9.

[0042] Among them, referring to Figure 2 、 Figure 4 and Figure 8 As shown, the conveying unit includes a swing assembly 6 and a first pushing assembly 7. The swing assembly 6 includes a number of drainage plates 64 that can swing left and right. The bottom of the conveying drainage plate 64 is in contact with the surface of the conveyor belt 9. The swing assembly 6 further includes a first support rod 61 fixed on the mounting plate 2. The first support rod 61 extends above the conveyor belt 9, and the length of the first support rod 61 is adapted to the width of the conveyor belt 9. A number of mounting rods 62 are evenly fixed on the first support rod 61 along the width direction of the conveyor belt 9. A rotating sleeve 63 is rotatably connected to the mounting rod 62. The drainage plate 64 is fixed on the rotating sleeve 63. It should be added that the bottom of the drainage plate 64 is provided with a high-temperature resistant and soft material.

[0043] During operation, through the left and right swinging of the drainage plate 64 on the surface of the conveyor belt 9, and at the same time, the bottom of the drainage plate 64 rubs against the surface of the conveyor belt 9 through the flexible material, so that the old materials flowing between the drainage plates 64 are less likely to stick to the surface of the conveyor belt 9. Moreover, with the left and right swinging of a number of drainage plates 64, a number of diversion channels are formed between the drainage plates 64. As the old materials are conveyed and flow on the conveyor belt 9, through the swinging of the drainage plate 64, the diversion direction of the formed diversion channels is continuously changed, realizing the stirring and mixing of the old materials. Moreover, with the change of the diversion channels, a physical diversion acceleration effect can also be achieved, making the old materials form a flowing effect on the conveyor belt 9. First, the conveying efficiency is improved, and the possibility of the old materials sticking to the conveyor belt 9 can also be reduced.

[0044] Furthermore, referring to Figures 2 - 5 and Figures 8 - 10As shown, since the recycled material itself has a certain viscosity and needs to be stirred and mixed by the diversion plate 64, it is necessary to increase the flow rate of the recycled material on the conveyor belt 9. That is to say, on the basis of the conveying speed of the conveyor belt 9, its flow rate on the conveyor belt 9 is further increased, so that two speeds are superimposed relative to the ground, improving the conveying efficiency while providing the support of the flow rate of the recycled material for the mixing and stirring of the diversion plate 64. Moreover, the swinging of the diversion plate 64 requires a periodic reciprocating force to drive it. Therefore, the present invention adopts a first pushing component 7 including a first rotating rod 71 rotatably arranged on the mounting plate 2 and a first driving gear 72 driven by a chain 5. The first driving gear 72 is arranged on the first rotating rod 71, the first driving gear 72 meshes with the chain 5, and the first rotating rod 71 is located above the baffle 10; at the same time, a reciprocating structure is arranged on the first rotating rod 71, and a plurality of diversion plates 64 realize reciprocating swinging through the reciprocating structure; a plurality of first rotating plates 76 are arranged at the discharge end of the diversion plate 64 on the first rotating rod 71, and a first scraping plate 77 is fixedly arranged at the end of the first rotating plate 76. The first scraping plate 77 is made of a high-temperature resistant and soft material.

[0045] During operation, while the transmission rod 4 rotates to drive the conveyor belt 9 to convey, it drives the chain 5 to rotate, so that the first driving gear 72 can be driven to rotate, thereby driving the rotation of the first rotating rod 71, realizing the multiple utilization of the conveying power of the conveyor belt 9; the rotation of the first rotating rod 71 can drive the reciprocating structure to perform periodic reciprocating motion, so as to drive the left and right swinging of a plurality of diversion plates 64. Moreover, the rotation of the first rotating rod 71 drives the rotation of a plurality of first rotating plates 76 and first scraping plates 77 arranged on the first rotating rod 71, forming a water wheel effect, accelerating the flow of the recycled material on the conveyor belt 9. And the first rotating plate 76 is arranged at the discharge end position of the diversion channel of the diversion plate 64. Then, during the rotation of the first rotating plate 76, the accelerated recycled material is directly conveyed into the diversion channel between a plurality of diversion plates 64 of a group of conveying units, and then, in cooperation with the swinging of the diversion plate 64, the accelerated circulation and mixing of the recycled material in the diversion channel are realized.

[0046] Secondly, the rotation of the first rotating plate 76 can also provide mixing and stirring for the recycled material on the conveyor belt 9, realizing multiple effect functions of the first rotating plate 76.

[0047] Furthermore, the reciprocating structure includes a reciprocating lead screw 75 fixedly arranged on the first rotating rod 71. The reciprocating lead screw 75 is located on the side of the baffle 10 away from the conveyor belt 9. A reciprocating plate 73 is engaged with the reciprocating lead screw 75. A limiting rod 74 is fixedly arranged on the side of the reciprocating plate 73 away from the baffle 10. The limiting rod 74 is slidably connected to the mounting plate 2. A second support rod 78 is fixedly arranged on the reciprocating plate 73. The second support rod 78 extends directly above the conveyor belt 9. A plurality of connecting rods 79 corresponding to the diversion plate 64 are fixedly arranged on the second support rod 78. A chute 710 is formed in the connecting rod 79. A sliding rod 711 is slidably connected in the chute 710. The sliding rod 711 is fixedly arranged at one end of the diversion plate 64 away from the rotation connection; moreover, the limiting rod 74 is adapted to the threaded area of the reciprocating lead screw 75.

[0048] It should be noted that corresponding covers can be provided directly above and directly below the conveyor belt 9 to prevent material from being thrown out and to catch the spilled material.

[0049] During operation, when the first rotating rod 71 rotates to drive the first rotating plate 76 to rotate, the reciprocating lead screw 75 is driven to rotate. Since the reciprocating plate 73 is engaged with it and the reciprocating plate 73 is limited by the limiting rod 74, the reciprocating plate 73 reciprocates on the reciprocating lead screw 75. Then, through the second support rod 78, the reciprocating motion of a plurality of connecting rods 79 is realized. Through Figure 4 and Figure 9 It can be seen that when the connecting rod 79 reciprocates in the width direction of the conveyor belt 9, the diversion plate 64 can be driven to swing around the first support rod 61 through the sliding rod 711, thereby providing power for the transformation of the diversion channel.

[0050] Further, referring to Figure 11As shown, since the initial velocity of the old material after heating and mixing is not enough when it enters the feed end of the conveyor belt 9, it is not conducive to the old material directly entering the first transmission unit, that is, the old material cannot form a rapid circulation in the guide channel formed by the first group of guide plates 64. Therefore, the present invention adopts a second pushing component 8 arranged at the feed end of the conveyor belt 9 on the mounting plate 2. The second pushing component 8 is used to accelerate the initial velocity of the old material entering the conveyor belt 9. The second pushing component 8 includes a second rotating rod 81 rotatably arranged on the mounting plate 2, and a second driving gear 82 is fixedly arranged on the second rotating rod 81 above the chain 5. The second driving gear 82 is meshed with the chain 5. A plurality of second rotating plates 83 are circumferentially fixedly arranged on the second rotating rod 81 between the two baffles 10, and a second scraper 84 is fixedly arranged at the end of the second rotating plate 83 away from the second rotating rod 81; it should be noted that the second scraper 84 also fits the surface of the conveyor belt 9, and the second scraper 84 is also made of high temperature resistant and soft material. In this way, when the processed old material is dumped at the feed end of the conveyor belt 9, the second rotating plate 83 is driven to rotate by the chain 5, so that when the old material falls into the feed end, the rotation of the second scraper 84 can accelerate the old material that has just entered the feed end, so that the old material obtains a certain initial velocity and then enters the first group of guide channels, and then combined with the transmission speed of the conveyor belt 9, it is mixed step by step in the guide channel formed by the guide plate 64.

[0051] Further, refer to Figure 1 As shown, in order to facilitate the dumping of the old materials after acceleration and mixing, a hopper 3 is provided at the discharge end of the conveyor belt 9.

[0052] By integrating stirring and scraping functions during the conveying process, a high degree of functional integration is achieved. On the traditional conveyor belt which only has the transfer function, multiple process links such as stirring, scraping, acceleration, etc. are integrated. All functions are derived from the main transmission system, breaking through the limitation that the existing conveying device can only complete material transfer, realizing the composite process of mixing while conveying, and improving the functional density and production efficiency of the equipment.

[0053] In summary, by integrating the key structures such as the guide plate 64, the first rotating plate 76, and the second rotating plate 83 on the conveyor belt 9, and by means of the power reuse mechanism of the transmission rod 4 and the chain 5, multiple functions such as acceleration, scraping, mixing and uniform distribution of old materials are realized during the conveying process; thereby effectively solving the problem that in the factory-mixed hot regeneration process, although the RAP performance can be restored by heating and adding new asphalt and regeneration agent, the existing conveying device can only complete the material transfer and lacks the function of further mixing during transportation. In addition, the adhesion of the recycled material causes it to easily stick and accumulate on the conveyor belt, affecting the smoothness of the discharge and production efficiency, showing the problem of insufficient functional integration and process adaptation.
