Description

Technical Field

[0001] The utility model relates to the technical field of asphalt pavement recycling, in particular to a feeding device for waste asphalt recycling and regeneration. Background Technique

[0002] After long-term use, asphalt pavements will inevitably be damaged. For asphalt pavements that need to be renovated, the damaged asphalt pavements need to be removed first, and then re-paved according to the design requirements. A large amount of waste pavement recycling materials will be generated, and these asphalt pavement recycling materials can still be reused as road materials after being processed.

[0003] In the prior art, when recycling waste asphalt, a feeding device is generally used to guide the waste materials into the recycling device. It generally connects the crushing device and the recycling device. After the waste asphalt is crushed by the crushing device, it is guided into the recycling device through the feeding device. Traditional feeding devices are generally hoppers and sieves. By placing the waste materials inside the hopper, the waste materials can fit against its inner wall and enter the recycling device. During this process, the sieve can screen out impurities in the asphalt, making the quality of the asphalt entering the recycling device relatively high.

[0004] However, in actual use, after long-term use, the sieve will be blocked by waste asphalt, which will affect the screening efficiency of the asphalt, making the asphalt unable to enter the recycling device normally, and thus affecting the recycling efficiency of waste asphalt. At this time, workers need to remove the bolts on the sieve from inside the hopper, and then they can remove the sieve. This process makes the operation of workers more troublesome, resulting in a lower efficiency of replacing the sieve, and thus the economic efficiency of using this feeding device is relatively low. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a feeding device for waste asphalt recycling and regeneration to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A feeding device for waste asphalt recycling and regeneration, including a box body, two threaded sleeves are slidably connected inside the box body, a cleaning brush is slidably connected to the lower side inside the threaded sleeve, a threaded rod is threadedly connected to the front side inside the threaded sleeve, and a guiding rod is slidably connected to the rear side inside the threaded sleeve.

[0007] Preferably, a plurality of installation grooves are opened inside the threaded sleeve, a rubber block is fixedly connected to the upper side of the inner wall of the installation groove, an installation block is fixedly connected to the bottom end of the rubber block, a push rod is fixedly connected to the bottom end of the installation block, and the bottom ends of the plurality of push rods are all fixedly connected inside the cleaning brush.

[0008] Preferably, four limiting grooves are formed in the lower side inside the threaded sleeve, a limiting block is slidably connected inside the limiting groove, and the four limiting blocks are respectively fixedly connected to the left and right sides outside the cleaning brush.

[0009] Preferably, two switch doors are hinged to the left side of the box body, four clamping grooves are formed at the left end of the box body, a clamping block is clamped inside the clamping groove, and collecting boxes are fixedly connected to the left ends of the upper and lower clamping blocks.

[0010] Preferably, the threaded rod is rotatably connected to the inner front side of the box body, and the guide rod is fixedly connected to the inner rear side of the box body.

[0023] In order to clearly and completely describe the purpose and technical solution of the present utility model, and make the advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model

[0024] Embodiment 1

[0025] Please refer to Figures 1-8 , the present utility model provides a technical solution: a waste asphalt recycling and regeneration feeding device, including a box body 1. Two threaded sleeves 2 are slidably connected inside the box body 1. A cleaning brush 3 is slidably connected to the lower side inside the threaded sleeve 2. A threaded rod 5 is threadedly connected to the front side inside the threaded sleeve 2. The threaded rod 5 is rotatably connected to the front side inside the box body 1. A guiding rod 4 is slidably connected to the rear side inside the threaded sleeve 2. The guiding rod 4 is fixedly connected to the rear side inside the box body 1. The upper and lower threaded sleeves 2 are arranged at equal intervals. The threaded sleeve 2 is matched with the guiding rod 4 and the threaded rod 5

[0026] The box body 1 plays a role in limiting the internal threaded sleeve 2, guiding rod 4, and threaded rod 5. Thus, when the threaded rod 5 is rotated, the threaded sleeve 2 can smoothly slide inside the guiding rod 4 and the threaded sleeve 2, so that the threaded sleeve 2 can stably drive the cleaning brush 3 to clean the sieve inside the box body 1, making the sieve not easily blocked, thereby reducing the number of times workers replace the sieve, reducing the use cost, and making the use economy of the device relatively high

[0027] Embodiment 2

[0028] On the basis of Embodiment 1, in order to improve the cleaning effect, a plurality of installation grooves 6 are opened inside the threaded sleeve 2. A rubber block 7 is fixedly connected to the upper side of the inner wall of the installation groove 6. The bottom end of the rubber block 7 is fixedly connected to an installation block 8. The installation block 8 is slidably connected inside the installation groove 6. The bottom end of the installation block 8 is fixedly connected to a push rod 9. The bottom ends of the plurality of push rods 9 are all fixedly connected to the inside of the cleaning brush 3

[0029] When installing the cleaning brush 3, the cleaning brush 3 slides upward along the upper side of the threaded sleeve 2, so that the cleaning brush 3 can push the push rod 9 and the mounting block 8 upward, and then the mounting block 8 can squeeze the rubber block 7 to generate elastic deformation inside the mounting groove 6. When the rubber block 7 moves in the reverse direction, the rubber block 7 can push the mounting block 8 and the push rod 9 downward, so that the push rod 9 can push the cleaning brush 3 downward, and then the cleaning brush 3 can be closely attached to the surface of the screen. Thus, when the threaded sleeve 2 moves, the cleaning brush 3 can clean the surface of the screen more neatly.

[0030] Embodiment III

[0031] On the basis of Embodiment II, in order to limit the cleaning brush 3 so that it will not fall off from the inside of the threaded sleeve 2, four limiting grooves 10 are opened on the lower side inside the threaded sleeve 2, and a limiting block 11 is slidably connected inside the limiting groove 10. The four limiting blocks 11 are respectively fixedly connected to the left and right sides of the outside of the cleaning brush 3.

[0032] The four limiting blocks 11 are respectively fixedly connected to the four corners of the outside of the cleaning brush 3. Thus, when the limiting block 11 slides inside the limiting groove 10, the cleaning brush 3 will not tilt, and the limiting block 11 can limit the position of the cleaning brush 3 sliding up and down, so that the cleaning brush 3 will not fall off from the inside of the threaded sleeve 2.

[0033] Embodiment IV

[0034] On the basis of Embodiment III, in order to automatically collect the impurities cleaned, two switch doors 15 are hinged on the left side of the box body 1. Four clamping grooves 12 are opened at the left end of the box body 1, and a clamping block 13 is clamped inside the clamping groove 12. The left ends of the upper and lower clamping blocks 13 are respectively fixedly connected with a collecting box 14. The upper and lower switch doors 15 are equidistantly distributed, and the switch door 15 matches the collecting box 14.

[0035] When the threaded sleeve 2 moves to the end of the stroke to the left, the threaded sleeve 2 can push the switch door 15 to rotate. At this time, the switch door 15 no longer blocks the box body 1, so that the impurities can directly fall into the inside of the collecting box 14. When the threaded sleeve 2 no longer fits the switch door 15, the switch door 15 will automatically reset under the influence of gravity, so that the box body 1 can be blocked. When it is necessary to clean the collecting box 14, by pulling the collecting box 14 upward, the clamping block 13 can fall off from the inside of the clamping groove 12. At this time, by pulling the collecting box 14 outward, the clamping block 13 can be separated from the clamping groove 12, so that the collecting box 14 can be conveniently emptied. On the contrary, by sliding the clamping block 13 into the inside of the clamping groove 12, the convex block of the clamping block 13 can be engaged with the inner wall of the clamping groove 12, so that the collecting box 14 will not fall off naturally.

[0036] In actual use, by rotating the threaded rod 5 respectively, it can drive the threaded sleeve 2 at the corresponding position to move, so that the threaded sleeve 2 can drive the cleaning brush 3 to clean the surface of the sieve mesh, so that the sieve mesh will not be easily blocked, and the workers do not need to frequently replace the sieve mesh, thus not affecting the recycling efficiency of waste asphalt, and making the use economy relatively high.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
