Description

Technical Field

[0001] This invention belongs to the field of asphalt production technology, specifically a waste asphalt material feeding device. Background Technology

[0002] Waste asphalt material comes from old asphalt pavements that need to be repaired or abandoned. In road design, recycling technology can restore its performance, thereby achieving secondary use, saving a lot of asphalt and aggregate materials, and reducing engineering costs. In the recycling process of waste asphalt material, a feeding device is needed to transport the waste asphalt material to a designated location for subsequent transfer.

[0003] Patent CN218618859U discloses a waste asphalt material feeding device, which includes a frame, a feeding hopper, a motor, and a conveyor belt. The motor is connected to one end of the frame and drives the conveyor belt. The conveyor belt is mounted on top of the frame. The feeding hopper is positioned above the end of the conveyor belt away from the motor and is supported by the frame. The feeding hopper has a discharge port at the end closest to the conveyor belt. Protective plates are fixedly connected to both sides of the feeding hopper near the conveyor belt. An upper baffle is connected to the protective plate at the end closest to the feeding hopper and away from the conveyor belt. This patent effectively prevents waste asphalt material from falling upon initial contact with the conveyor belt, ensuring stable conveying of the waste asphalt material.

[0004] However, the above technical solutions still have the following shortcomings in practical applications:

[0005] The feeding operation involves placing waste asphalt material on a conveyor belt and transporting it to the next process. However, in some cases, waste asphalt material is divided into different types, each requiring different processing. When different types of material are placed on the conveyor belt, they may mix due to vibration, collapse, or other reasons, affecting subsequent processing. Furthermore, in some cases, multiple collection boxes need to be placed at the end of the conveyor belt to collect different types of material. If the distribution area of ​​the material on the conveyor belt is larger than the inlet of the collection box, the material may not fall accurately into the designated collection box but instead fall into other collection boxes, resulting in different types of material being in the same collection box, causing problems. Increasing the number of conveyor belts to avoid this situation is also cumbersome and costly. Summary of the Invention

One side of adjusting plate one is attached to one side of the limiting plate. One side of adjusting plate two is attached to one side of the fastening plate.

[0014] Preferably, a slide rod is fixedly connected to one side of the second adjusting plate, the slide rod is inserted into and slidably connected to one side of the inner cavity of the first adjusting plate, and a spring is sleeved on one side of the slide rod, one end of the spring is fixedly connected to one side of the second adjusting plate, and the other end is fixedly connected to one side of the inner cavity of the first adjusting plate.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The waste asphalt material feeding device of the present invention utilizes an adaptive material separation mechanism with an adaptable inlet size. When different types of waste asphalt materials are fed on the conveyor belt, each material has an independent conveying channel, preventing mixing of different types of materials on the conveyor belt and ensuring material purity. Furthermore, the width of the conveying channel matches the specifications of the collection box inlet, allowing materials to fall precisely into the collection box. This avoids situations where the material distribution range on the conveyor belt exceeds the collection box inlet, causing materials to fall outside the collection box or into other collection boxes. Moreover, compared to methods that make the conveying channel too narrow, this... This method of adjusting the width of the conveyor channel to match the width of the collection box inlet maximizes the collection speed of the collection box. Furthermore, because the collection box is blocked on all sides, when materials enter the collection box, even if they splash outwards, they will be intercepted and slide back into the collection box under the action of gravity, thus further ensuring the collection of materials. Moreover, by adjusting the spacing between adjacent limit plates, the spacing between adjacent limit plates can be reduced, allowing more limit plates and fastening plates to be placed above the conveyor belt. This allows for the placement of the maximum number of collection boxes at the end of the conveyor belt, which is beneficial for increasing the variety and quantity of materials conveyed.

[0021] 2. The waste asphalt material feeding device of the present invention utilizes a telescopic material control mechanism. Plate 1 and Plate 2 can divide the inside of the collection box into multiple independent placement areas. Material falling from the end of Plate 1 falls into the independent placement area. Even if the material rolls, it will only stay in this placement area. When the material tends to stabilize, the position of the independent placement area is adjusted again until the material is evenly placed in the collection box. Furthermore, the area of ​​the independent placement area can be adjusted by adjusting the distance between the two Plates 2 to adapt to different collection needs. This avoids the material rolling due to impact when falling into the collection box, thus preventing the material from deviating from its original falling position and further ensuring that the material is evenly distributed in the collection box.

[0035] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please refer to Figures 1-11 The present invention provides a technical solution: a waste asphalt material feeding device, including a frame 1, a conveyor belt 2 on the frame 1, and a feed inlet size adaptive material separation mechanism on the conveyor belt 2 for separating different types of materials.

[0037] The feed inlet size adaptive material separation mechanism includes multiple slot plates 3 arranged laterally and fixedly connected to one side of the frame 1. A limit plate 4 is slidably connected to the slot of the slot plate 3. Two connecting rods 6 are rotatably arranged on one side of the limit plate 4. A connecting rod 7 is rotatably arranged at one end of the connecting rod 6. A fastening plate 8 is rotatably arranged at one end of the connecting rod 7. The bottom of the limit plate 4 and the fastening plate 8 are both in contact with the upper end of the conveyor belt 2. A clamping plate 22 is slidably connected to one side of the limit plate 4. A clamping plate 23 is slidably connected to one side of the fastening plate 8. The clamping plate 22 and the clamping plate 23 are inserted and slidably connected. A baffle 24 is fixedly connected to one side of the frame 1. One end face of the baffle 24 is in contact with one side of the limit plate 4 and the fastening plate 8. The limit plate 4 and the fastening plate 8 cooperate with each other to clamp the material collection box.

[0038] In this embodiment, as Figures 1-6 , Figure 9 , Figure 10 As shown, a threaded rod 27 is threadedly connected to one side of the upper end of the limiting plate 4. One end of the threaded rod 27 is rotatably mounted on the slot plate 3, and the other end is rotatably mounted on the frame 1. A rotating wheel 32 is fixedly connected to one end of the threaded rod 27.

[0039] One end of the limiting plate 4 is fixedly connected to a motor 5, and the output end of the motor 5 is fixedly connected to one end of the connecting rod 6.

[0040] A spring 26 is fixedly connected to one side of the clamp 22, and the other end of the spring 26 is fixedly connected to the limiting plate 4.

[0041] Specifically, in existing technologies, waste asphalt material is placed on a conveyor belt and transported to the next process to achieve the feeding operation. However, in some cases, waste asphalt material is divided into different types, and different types of material require different treatments. When different types of material are placed on the conveyor belt, the materials may mix due to vibration, collapse, etc., which will affect the subsequent processing of the materials. In addition, in some cases, multiple collection boxes need to be placed at the end of the conveyor belt to collect different types of materials. When the distribution range of the material on the conveyor belt is larger than the inlet of the collection box, the material will not fall into the designated collection box accurately, but will fall into other collection boxes instead, resulting in different types of materials being in the same collection box, causing trouble. Increasing the number of conveyor belts to avoid this situation is also quite troublesome and costly.

[0042] Therefore, in order to avoid the above problems, in this embodiment, when using the material to be fed, multiple rectangular collection boxes are placed at the ends of the limiting plate 4 and the fastening plate 8, and are located between the limiting plate 4 and the fastening plate 8. The rectangular collection boxes are common collection containers in industry.

[0043] Furthermore, one side of the collection box is attached to one side of the baffle 24. Then, the motor 5 drives the connecting rod 6 to rotate. Under the action of the connecting rod 6 and the second connecting rod 7, the distance between the limiting plate 4 and the fastening plate 8 can be adjusted. The limiting plate 4 and the fastening plate 8 clamp the collection box. When the distance between the limiting plate 4 and the fastening plate 8 changes, the clamping plate 22 and the second clamping plate 23 also slide relative to each other. Under the action of the second spring 26, the clamping plate 22 and the second clamping plate 23 are attached to one side of the collection box. At this time, the collection box is not only positioned, but also... Surrounded by limiting plates 4, baffles 24, fastening plates 8, clamping plates 1 and 23, the opening of the collection box is aligned with the end of the conveyor belt 2. Furthermore, workers can rotate the threaded rod 37 by turning the rotating wheel 32 to adjust the distance between adjacent limiting plates 4, minimizing the distance between them. This allows more limiting plates 4 and fastening plates 8 to be positioned above the conveyor belt 2, enabling the placement of the maximum number of collection boxes at its end within the limited width of the conveyor belt 2. This is beneficial for increasing the variety and quantity of materials conveyed. Different types of materials are then placed in the conveying channels formed by different limiting plates 4 and fastening plates 8, and the conveyor belt 2 is driven to operate, thus conveying and feeding the materials. Since each type of material has an independent conveying channel, different types of materials will not mix on the conveyor belt 2, ensuring the purity of the materials. Furthermore, the width of the conveying channel matches the specifications of the collection box inlet, allowing the materials to fall accurately into the collection box. This avoids situations where the material distribution range on the conveyor belt 2 is larger than the collection box inlet, causing the materials to fall outside the collection box or into other collection boxes. Compared to setting the conveying channel too narrow, this method of adjusting the width of the conveying channel to match the width of the collection box inlet maximizes the collection speed of the collection box. Moreover, since the collection box is blocked on all sides, when materials enter the collection box, even if they splash outwards, they will be intercepted and slide back into the collection box under the action of gravity, thereby further ensuring the collection of materials.

[0044] In this embodiment, as Figure 4 , 6 - Figure 8 , Figure 10 , Figure 11 As shown, a telescopic material control mechanism is also provided on the limit plate 4;

[0045] The telescopic material control mechanism includes a threaded block 18 slidably connected to one side of the upper end face of the limiting plate 4. A sliding rod 16 is fixedly connected to one side of the upper end face of the threaded block 18. A groove plate 14 is slidably connected to the sliding rod 16. A fixing rod 12 is fixedly connected to one side of the lower end of the groove plate 14. A displacement rod 13 is slidably connected to the groove at the lower end of the groove plate 14. A plate body 11 is fixedly connected to the lower end of both the fixing rod 12 and the displacement rod 13. A plate body 10 is inserted into and slidably connected to the inner side of the plate body 11. An adjusting plate 20 is fixedly connected to the lower end of the threaded block 18. An adjusting plate 21 is inserted into and slidably connected to the inner side of the adjusting plate 20. One side of the plate body 21 is attached to one side of the limiting plate 4. One side of the plate body 10 is attached to one side of the fastening plate 8. One side of the adjusting plate 20 is attached to one side of the limiting plate 4. One side of the adjusting plate 21 is attached to one side of the fastening plate 8. The bottom of the adjusting plate 20 and the adjusting plate 21 are attached to the upper surface of the conveyor belt 2.

[0046] A sliding rod 29 is fixedly connected to one side of the adjusting plate 21. The sliding rod 29 is inserted into and slidably connected to one side of the inner cavity of the adjusting plate 1 20. A spring 3 28 is sleeved on one side of the sliding rod 29. One end of the spring 3 28 is fixedly connected to one side of the adjusting plate 21, and the other end is fixedly connected to one side of the inner cavity of the adjusting plate 1 20.

[0047] A spring 9 is fixedly connected to one side of plate 10, and the end of spring 9 away from plate 10 is fixedly connected to one side of the inner cavity of plate 21.

[0048] A threaded rod 17 is threadedly connected to one side of the threaded block 18. Both ends of the threaded rod 17 are rotatably mounted on the limiting plate 4. A motor 25 is fixedly connected to one side of the limiting plate 4. The output end of the motor 25 is fixedly connected to one end of the threaded rod 17.

[0049] A threaded rod 15 is threadedly connected to one side of the slot plate 2 14. The lower end of the threaded rod 15 is rotatably mounted on the threaded block 18. A motor 2 19 is fixedly connected to one side of the threaded block 18. The output end of the motor 2 19 is fixedly connected to one end of the threaded rod 15.

[0050] The upper end of the displacement rod 13 is threadedly connected to a threaded rod 30. Both ends of the threaded rod 30 are rotatably mounted on the slot plate 14. A motor 31 is fixedly connected to one side of the slot plate 14. The output end of the motor 31 is fixedly connected to one end of the threaded rod 30.

[0051] Specifically, in the above embodiments, although the material can fall accurately into the collection box, the orientation of the material when falling into the collection box is fixed. Therefore, the material may accumulate locally in the collection box. When the collection box is removed from between the limiting plate 4 and the fastening plate 8, the material accumulated at the edge of the collection box can easily fall out, thus affecting the normal transfer of the material. Therefore, to solve this problem, when the material falls into the collection box from the end of the conveyor belt 2, it will pass through the adjusting plate 1 20 and the adjusting plate 21. The adjusting plate 21 will be kept in close contact with the fastening plate 8 under the action of the spring 3 28. Therefore, it can be controlled by the motor. The method of rotating the threaded rod 17 driven by the third 25 causes the adjusting plate 20 to move on the surface of the conveyor belt 2, and the adjusting plate 20 is always partially in contact with the conveyor belt 2. On this basis, the other end of the adjusting plate 20 moves above the collection box. By controlling the position of the end of the adjusting plate 20, the material can fall into different areas of the inner cavity of the collection box in a regular manner and be evenly distributed inside the collection box. This avoids the situation where the material accumulates locally inside the collection box, causing the material to be too high in some areas. When the collection box is removed from between the limiting plate 4 and the fastening plate 8, the material accumulated at the edge of the collection box is easy to fall out through the edge of the collection box, affecting the normal transfer of materials.

[0052] Although the falling direction of the material can be controlled through the above method, since the waste asphalt material includes stones, these stones are prone to rolling due to impact when they fall into the collection box. Even if the falling direction of the material can be controlled, the material may still deviate from its original falling position. Therefore, to avoid this situation, motor 219 drives threaded rod 15 to rotate, causing trough plate 214 to descend until the bottom of plate 10 and plate 21 are in contact with the bottom of the inner cavity of the collection box. Plate 10 is also in contact with the inner wall of the collection box under the action of spring 19. At this time, the two plates 10 and 21 form an independently placed... The independent placement area serves as the original falling position. Materials falling from the end of the adjusting plate 20 fall into this independent placement area. Even if the materials roll, they will only remain in this placement area. Once the materials stabilize, the position of the independent placement area is adjusted again until the materials are evenly placed in the collection box. Furthermore, the distance between the two plates 11 can be adjusted by the rotation of the threaded rod 30 driven by the motor 31 to adjust the area of ​​the independent placement area to adapt to different collection needs. This prevents the materials from rolling due to impact when falling into the collection box, thus avoiding the situation where the materials deviate from the original falling position and further ensuring that the materials are evenly distributed in the collection box.

[0053] Working principle: Based on the required type and quantity of materials to be fed, multiple rectangular collection boxes are placed at the ends of the limiting plate 4 and the fastening plate 8, positioned between them, with one side of the collection box against the side of the baffle 24. Then, motor 5 drives connecting rod 6 to rotate. Under the action of connecting rod 6 and connecting rod 7, the distance between the limiting plate 4 and the fastening plate 8 is adjusted, clamping the collection box. Furthermore, when the distance between the limiting plate 4 and the fastening plate 8 changes, clamping plates 22 and 23 also slide relative to each other. Under the action of spring 26, clamping plates 22 and 23 are brought into contact with one side of the collection box. At this point, the collection box is not only positioned but also held in place by the limiting plate 4, baffle 24, fastening plate 8, and clamping plates 24 and 24. 2. The clamping plate 23 surrounds the conveyor belt 2, with the opening of the collection box aligned with the end of the conveyor belt 2. The worker can rotate the rotating wheel 32 to rotate the threaded rod 27, adjusting the distance between adjacent limiting plates 4 to minimize this distance. This allows more limiting plates 4 and fastening plates 8 to be positioned above the conveyor belt 2, maximizing the number of collection boxes that can be placed at the end of the conveyor belt 2, given its limited width. This facilitates the transport of a wider variety of materials. Different types of materials are then placed in the transport channels formed by different limiting plates 4 and fastening plates 8, driving the conveyor belt 2 to transport and load materials. Since each material has its own independent transport channel, different types of materials will not mix on the conveyor belt 2. This ensures the purity of the material. Furthermore, the width of the conveyor channel matches the specifications of the collection box inlet, allowing the material to fall precisely into the collection box. This prevents material from falling outside the collection box or into other collection boxes due to the material's distribution range on the conveyor belt being larger than the collection box inlet. Compared to setting the conveyor channel too narrow, this method of adjusting the conveyor channel width to match the collection box inlet width maximizes the collection speed of the collection box. Moreover, because the collection box is blocked on all sides, even if material splashes outwards when entering the collection box, it will be intercepted and slide back into the collection box under gravity, further ensuring the collection of the material. When the material falls from the end of conveyor belt 2 into the collection box, it passes through adjusting plate 1 (20) and adjusting plate 2 (21). Adjusting plate 2 (21) is kept in close contact with fastening plate 8 by spring 3 (28). Therefore, adjusting plate 1 (20) can be moved on the surface of conveyor belt 2 by rotating threaded rod 2 (27) driven by motor 3 (25), ensuring that a portion of adjusting plate 1 (20) is always in contact with conveyor belt 2. Furthermore, the other end of adjusting plate 1 (20) moves above the collection box. By controlling the position of the end of adjusting plate 1 (20), the material can be regularly deposited into different areas of the collection box cavity and evenly distributed inside, thus preventing localized accumulation of material and excessive material in certain areas. When the collection box is removed from between limiting plate 4 and fastening plate 8...Material accumulating at the edge of the collection box is prone to falling out, affecting normal material transfer. Although the falling direction of the material can be controlled through the above method, since the waste asphalt material includes stones, when the stones fall into the collection box, they are prone to rolling due to impact. Even if the falling direction of the material can be controlled, the material may still deviate from the original falling position. Therefore, to avoid this situation, motor 219 drives the threaded rod 15 to rotate, causing the trough plate 214 to descend until the bottom of plate 10 and plate 21 are in contact with the bottom of the inner cavity of the collection box, and plate 10 is in contact with the inner wall of the collection box under the action of spring 19. At this time, the two plates 11 0. An independent placement area is formed between plates 11. This independent placement area serves as the original falling position. Material falling from the end of plate 20 falls into this independent placement area. Even if the material rolls, it will only remain within this placement area. Once the material stabilizes, the position of the independent placement area is adjusted again until the material is evenly distributed in the collection box. Furthermore, the distance between the two plates 11 can be adjusted by rotating the threaded rod 30 driven by motor 31, thereby adjusting the area of ​​the independent placement area to accommodate different collection needs. This prevents the material from rolling due to impact when falling into the collection box, thus avoiding deviation from the original falling position and further ensuring that the material is evenly distributed in the collection box.
