Description

Technical Field

[0001] The present invention relates to the technical field of crushing and screening devices, and in particular to a crushing and screening device for waste asphalt mixture. Background Art

[0002] In recent years, in response to the country's requirements for building a conservation-oriented society and developing a circular economy, coupled with the increase in the prices of oil and stone resources, highway departments in various places have taken active actions, aiming at sustainable development and developing green transportation. The recycling and reuse of old road asphalt materials has regained attention, and many scientific research institutions and research institutes have begun to study and promote the recycling and reuse technology of old road asphalt materials.

[0003] In the prior art, the old asphalt needs to be placed in a crusher for crushing, and then the crushed old asphalt needs to be placed in a screening machine for screening.

[0004] For example, in the prior art, Chinese patent application No. 202120814210.X describes an intelligent flexible crushing and screening device for waste asphalt mixtures. This device uses an inclined plate to convey the crushed waste asphalt mixture. However, this design is not very ideal, as the inclined plate makes it difficult to completely push the crushed waste asphalt mixture out. Furthermore, when screening the waste asphalt mixture, the screening effect is not very good. There are two specific reasons for this: the screen may become blocked, resulting in poor screening effect, and small volumes of waste asphalt mixture may be removed from the outlet of the large volume of waste asphalt mixture during screening.

[0005] In view of the above problems, we designed a crushing and screening device for waste asphalt mixture, which can screen the crushed waste asphalt mixture well and stably remove the screened waste asphalt mixture of different sizes from different outlets. Summary of the Invention

[0067] The other structures are the same as those in the first embodiment.

[0068] In this embodiment, in the initial state, the filter plate 6 and the mounting plate 7 are kept horizontal. The two second drive motors 41 are then activated, causing the two crushing rollers 38 to perform a crushing operation. The waste asphalt mixture to be crushed is then poured between the two guide plates 37, allowing the waste asphalt mixture to enter between the two crushing rollers 38 for crushing.

[0069] At this point, the hydraulic cylinder 23 is activated, causing the third gear 15 to mesh with the first gear 12. The first drive motor 10 is then activated and rotated back and forth. The first drive motor 10 drives the third gear 15 to rotate.

The connection between the second connecting plate 9 and the first connecting plate 8 allows the two second sleeve plates 32 to slide synchronously along the auxiliary slide bar 42. The upward and downward movement of the second sleeve plate 32 drives the impact rubber column 33 to strike the filter plate 6 and the placement plate 7, allowing the small volume of waste asphalt mixture on the filter plate 6 to fall stably onto the placement plate 7.

[0070] After crushing is completed and no more waste asphalt mixture falls from the filter plate 6 onto the placement plate 7, the hydraulic cylinder 23 is activated to engage the third gear 15 with the second gear 14, and the first drive motor 10 is activated to rotate the spline shaft 20 and the second threaded rod 13. At this time, the second sliding plate 17, the second limit slider 19, and the first tooth 24 move upward. At this time, the first tooth 24 engages with the fourth gear 26, causing the rotating column 35 and the auxiliary slider 42 to rotate, causing the filter plate 6 and the placement plate 7 to tilt at a certain angle, so that the filter plate 6 and the placement plate 7 are pressed against the two guide inclined plates 3 respectively.

[0071] At this time, the fifth gear 28 and the second tooth 25 remain in meshing state, and the first sliding plate 31 and the second sliding plate 32 move downward. The device remains in a stable state.

[0072] Then start the hydraulic cylinder 23 to make the third gear 15 mesh with the first gear 12, and then start the first drive motor 10 to make the elastic ball on the impact rubber column 33 continue to impact the filter plate 6 and the placement plate 7, so as to facilitate the stable removal of the waste asphalt mixture on the filter plate 6 and the placement plate 7 from the guide inclined plate 3 and the discharge port 40, and collect waste asphalt mixtures of different sizes at different discharge ports 40 through different external collection frames, thereby completely abandoning the crushing and screening of the asphalt mixture.
