Description

Technical Field

[0001] This utility model relates to the field of asphalt pavement material recycling technology, specifically to a RAP recycling barrel cleaning device. Background Technology

[0002] RAP (Recycled Asphalt Pavement Material) recycling bins are widely used in road construction and maintenance. Their main function is to heat, dry, and recycle old asphalt materials. However, due to the high temperature and viscosity of the asphalt material during the recycling process, a thick layer of asphalt residue often adheres to the inner wall of the RAP recycling bin. This residue is quite hard, and long-term accumulation not only affects the volume utilization rate of the bin but may also cause uneven heating, blockage, and reduced equipment efficiency.

[0003] Current cleaning methods are mostly manual, involving workers using hammers, chisels, and other tools to knock and clean the inner wall of the barrel. This method is labor-intensive, inefficient, and carries high safety risks. Furthermore, because manual cleaning is difficult to apply evenly to the inner wall of the barrel, the cleaning effect is unsatisfactory, and residual asphalt is often not completely removed, further affecting recycling efficiency and equipment lifespan.

Therefore, the exemplary term “down” can encompass both up and down orientations.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] The present invention will now be described in detail with reference to the accompanying drawings: A RAP recycling barrel cleaning device of the present invention includes a base 1 and a lifting mechanism 2. The base 1 is mounted on the lifting mechanism 2. The bottom of the lifting mechanism 2 is equipped with casters to facilitate equipment movement. The base 1 is movably mounted on the lifting mechanism 2. A mounting plate 6 is mounted on the base 1 via a connecting frame. A support disc 10 is slidably mounted on the mounting plate 6. Four first electric cylinders 11 are arranged in a circumferential array on the support disc 10. The movable end of the first electric cylinder 11 is connected to an air hammer 13 via a shock-absorbing pad 12. The movable end of the air hammer 13 is connected to a striking head 15. The end of the striking head 15 is conical to efficiently strike the asphalt clumps on the inner wall of the barrel, thereby breaking and removing the asphalt clumps. A control console 20 is provided on the lifting mechanism 2 for controlling the various components.

[0029] The mounting plate 6 is equipped with a second electric cylinder 16 arranged in a circular array along its circumference. The movable end of the second electric cylinder 16 is connected to a locking block 17. When using the equipment, move the equipment to one end of the RAP regeneration tank, control the lifting mechanism 2 to make the axis of the support disc 10 and the RAP regeneration tank nearly coincide, and then control the second electric cylinder 16 to make each locking block 17 press against the outer wall of one end of the regeneration tank, thereby ensuring that the support disc 10 and the RAP regeneration tank are coaxial.

[0030] The base 1 is provided with an annular boss 3, and the end of the annular boss 3 is provided with a retaining ring. The lifting mechanism 2 is provided with a travel groove 4 that cooperates with the annular boss 3 and the retaining ring. A spring 5 is provided between the bottom of the travel groove 4 and the base 1. This design allows the base 1 to have a free vertical travel, so that the height adjustment of the lifting mechanism 2 has a certain tolerance. Otherwise, rigid height adjustment would make it difficult to lock the locking operation of each locking block 17.

[0031] Linear bearings 7 are arranged in a circular array along the mounting plate 6. A guide rod 8 is slidably arranged inside the linear bearing 7. One end of the guide rod 8 is connected to the support disc 10. The guide rod 8 can play the role of support and guidance. A third electric cylinder 9 is arranged on the mounting plate 6. The movable end of the third electric cylinder 9 is connected to the support disc 10. By driving the third electric cylinder 9, the support disc 10 can be moved left and right.

[0032] The movable end of the air hammer 13 is connected to a mounting plate 14, on which striking heads 15 are arranged. The ends of the striking heads 15 are tapered. Preferably, the height of the striking heads 15 in the middle row is greater than the height of the striking heads 15 at the edges. Figure 4 As shown.

[0033] The mounting plate 6 is provided with an air pipe through hole 18, and the lifting mechanism 2 is provided with an air compressor 19. The air compressor 19 is connected to the air hammer 13 through a solenoid valve and an air pipe, and the air pipe passes through the air pipe through hole 18.

[0034] After all the locking blocks 17 are locked, the control activates the third electric cylinder 9, causing the support disc 10 to reach the initial working point; the control activates the first electric cylinder 11, causing the striking head 15 to reach the inner wall of the RAP recycling tank; then the air compressor 19 is started, and the air hammer 13 is operated by controlling the solenoid valve to drive the striking head 15 to strike the asphalt clumps on the inner wall of the recycling tank. During the cleaning process, the recycling tank itself needs to rotate.

[0035] The extension length of the piston rod of the first electric cylinder 11 should be set or controlled on the control panel 20 according to the inner diameter of the RAP regeneration tube, and should ensure that the striking head 15 does not hit the inner wall of the RAP regeneration tube when it strikes.

[0036] The distance the piston rod of the third electric cylinder 9 moves each time should be based on the length of the mounting plate 14. That is, the distance the piston rod of the third electric cylinder 9 moves each time is the length of the mounting plate 14. The total moving distance of the third electric cylinder 9 needs to be set on the control panel 20 according to the specifications of the RAP regeneration tank. Input the working length (from the cleaning start point to the cleaning end point) into the control panel 20. This length is the maximum stroke of the third electric cylinder 9.

[0037] The time interval between each action of the third electric cylinder 9 should be set according to the rotation speed of the RAP regeneration tank or the cleaning effect. When there are 4 air hammers 13, the time required for the RAP regeneration tank to rotate 90° is calculated based on its rotation speed. This time is the action time interval of the third electric cylinder 9. This time interval can also be appropriately extended according to the working conditions.

[0038] After the cleaning work is completed, the control stops the air compressor 19; the control retracts the piston rods of the first electric cylinder 11 and the third electric cylinder 9, and the control extends the piston rod of the second electric cylinder 16, and then the equipment is removed.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
