[0027] The present invention discloses a high-performance asphalt mixture production device for ultra-thin bridge deck paving. When in use, the power mechanism 6 is turned on to drive the mixing mechanism 5 to operate; then the matrix asphalt spraying mechanism 7 is connected to a feed pipe with a high-pressure pump, and the other end of the feed pipe is connected to a matrix asphalt storage tank, so that the matrix asphalt in the matrix asphalt storage tank is sprayed into the mixing barrel 1; and when spraying the matrix asphalt, the asphalt modifier and other fixed reinforcement materials are simultaneously fed into the mixing barrel 1 through multiple solid material feeding ports, so that the matrix asphalt and the various fixed reinforcement materials falling from top to bottom are offset and mixed, thereby improving the mixing uniformity of the fixed reinforcement materials and the matrix asphalt; and the heating mechanism can be turned on to heat the mixture in the mixing barrel 1, and the matrix asphalt, asphalt modifier and other fixed reinforcement materials are mixed and stirred by the mixing mechanism 5. After stirring evenly, a finished asphalt mixture is obtained, which can be discharged through the discharge pipe 4. The asphalt mixture processed by the present invention has high performance.

[0028] An outer shell 101 is sleeved on the outer cylinder surface of the mixing cylinder 1, and a pumping chamber is formed between the outer shell 101 and the mixing cylinder 1, and the pumping chamber is connected to multiple pumping holes at the lower end of the outer cylinder surface of the mixing cylinder 1; a sealed sliding pumping disk 102 is provided in the pumping chamber, and the pumping disk 102 is located above the pumping holes; the pumping disk 102 is fixed to the lower end of multiple vertical sliding shafts 103, and the middle parts of the multiple vertical sliding shafts 103 are sealed and slid on the top plate of the outer shell 101, and sliding rings are fixed to the upper ends of the multiple vertical sliding shafts 103, and a T-shaped frame 104 is connected to the sliding ring, and the T-shaped frame 104 is connected to the power mechanism 6.

[0029] An outer shell 101 is welded on the outer cylinder surface of the mixing cylinder 1, and a pumping chamber is formed between the outer shell 101 and the mixing cylinder 1, so that the mixed material of the base asphalt, asphalt modifier and other fixed reinforcement materials in a mixed state can reciprocate inside the mixing cylinder 1 and inside the pumping chamber; when in use, After the power mechanism 6 is started, it can not only drive the mixing mechanism 5 to operate, but also drive the T-shaped frame 104 to perform reciprocating sliding motion in the up and down directions. When the T-shaped frame 104 moves upward, the cooperation of the sliding ring and multiple vertical sliding shafts 103 drives the pumping plate 102 to slide upward in the pumping chamber in a sealed manner, thereby pumping the mixture inside the mixing barrel 1 into the pumping chamber through multiple pumping holes; when the T-shaped frame 104 moves downward, the cooperation of the sliding ring and multiple vertical sliding shafts 103 drives the pumping plate 102 to slide downward in the pumping chamber in a sealed manner, thereby pressing the mixture inside the pumping chamber back into the mixing barrel 1 through multiple pumping holes, thereby realizing the reciprocating flow of the mixture inside the mixing barrel 1 and the pumping chamber, so that the mixture is in a flowing state, improving the mixing effect of the mixture, and improving the performance of the asphalt mixture produced and processed.

[0030] The power mechanism 6 includes a power motor 601 installed on the barrel cover 3, a driving pulley is fixed on the output shaft of the power motor 601, and the driving pulley is connected to a synchronous pulley fixed on a rotating shaft 602 through a synchronous belt, and the rotating shaft 602 rotates on the barrel cover 3; a driving bevel gear 603 fixed at one end of the rotating shaft 602 is connected to the mixing mechanism 5; one end of a swing arm 604 is fixed to the other end of the rotating shaft 602, and the other end of the swing arm 604 is threadedly connected to a linkage screw, and the linkage screw is inserted into the linkage horizontal hole of the T-shaped frame 104.

[0031] After the power motor 601 inside the power mechanism 6 is started, it can drive the driving pulley to rotate, and the driving pulley drives the synchronous pulley to rotate through the synchronous belt, thereby driving the rotating shaft 602 to rotate through the synchronous pulley. When the rotating shaft 602 rotates, it drives the driving bevel gear 603 to rotate, and the mixing mechanism 5 can be driven to operate through the driving bevel gear 603; when the rotating shaft 602 rotates, it can also drive the swing arm 604 to rotate and orbit, and when the swing arm 604 moves, it can drive the T-shaped frame 104 to reciprocate in the up and down directions through the cooperation of the linkage screw and the linkage horizontal hole.

[0032] Two vertical racks are fixed on both sides of the T-shaped frame 104, and a linkage gear 105 is meshed on the outer side of the two vertical racks respectively. The two linkage gears 105 are fixed on the outer ends of two linkage shafts 106. The two linkage shafts 106 are sealed and rotated side by side on the mixing barrel 1. A flip material plate 107 is fixed in the middle of the two linkage shafts 106. The two flip material plates 107 are relatively arranged inside the mixing barrel 1 and are located at both ends of the mixing mechanism 5.

[0033] When the T-shaped frame 104 performs reciprocating motion in the up and down directions, it can drive the two vertical racks to perform reciprocating motion up and down, so that the two vertical racks can mesh with the two linkage gears 105 to perform reciprocating rotation motion. When the two linkage gears 105 rotate, they can drive the two flip material plates 107 to swing back and forth inside the mixing barrel 1 through the two linkage shafts 106. When the two flip material plates 107 swing, the asphalt modifier and other fixed reinforcement materials fed into the mixing barrel 1 from multiple solid material feeding ports can be broken up, so that the asphalt modifier and other fixed reinforcement materials are dispersed and fall, thereby improving the uniformity of dispersion, which is beneficial to improving the mixing effect of the asphalt modifier and other fixed reinforcement materials with the sprayed base asphalt.

[0034] The mixing mechanism 5 includes a mixing vertical shaft 501, and a driven bevel gear fixed on the mixing vertical shaft 501 is vertically meshed with a driving bevel gear 603; the middle part of the mixing vertical shaft 501 is sealed and rotated on the cylinder cover 3, and the mixing vertical shaft 501 is inserted into a fixed center seat at one end of the mixing cylinder 1, and a plurality of mixing impellers 502 are evenly fixed on the center seat; and a plurality of mixing impellers 502 are each provided with a plurality of material feeding grooves.

[0035] When the active bevel gear 603 rotates, it can mesh with the driven bevel gear to rotate, thereby driving the mixing vertical shaft 501 to rotate. When the mixing vertical shaft 501 rotates, it can drive the center seat and the multiple stirring impellers 502 thereon to rotate in the mixing barrel 1, so as to further mix and stir the base asphalt, asphalt modifier and other fixed reinforcing materials that are sprayed and mixed together, so as to fully mix them evenly; multiple material feeding grooves are provided on the multiple stirring impellers 502, which is beneficial to reduce the resistance during stirring and improve the dispersion effect.

[0036] The mixing mechanism 5 also includes a movable connecting rod 503, one end of the movable connecting rod 503 is rotatably connected to the flip material plate 107, and the other end of the movable connecting rod 503 is rotatably connected to the annular slide 504. The annular slide 504 slides on the mixing vertical axis 501. The annular slide 504 is rotatably connected to the upper ends of multiple movable inclined rods 505. The limiting horizontal axis 506 fixed at the lower ends of the multiple movable inclined rods 505 slides in the horizontal slideway on the multiple stirring impellers 502.

[0037] When the flip material plate 107 performs reciprocating swinging motion, it can drive one end of the movable connecting rod 503 to move in the up and down direction, and the other end of the movable connecting rod 503 drives the annular slide 504 to reciprocate in the up and down direction. When the annular slide 504 moves, it drives the upper ends of the multiple movable inclined rods 505 to move up and down, and the lower ends of the movable inclined rods 505 drive the multiple limiting horizontal shafts 506 to slide back and forth in the horizontal slides on the multiple stirring impellers 502, thereby continuously changing the inclination angles of the multiple movable inclined rods 505, thereby driving the contact positions of the multiple movable inclined rods 505 with the mixed material to continuously change, which is beneficial to improving the uniformity of mixing the mixed materials at different positions.

[0038] The matrix asphalt spraying mechanism 7 includes an annular spraying pipe 701 located inside the mixing barrel 1, and a plurality of injection holes are evenly arranged on the top surface of the annular spraying pipe 701; the annular spraying pipe 701 is fixed to one end of the diversion elbow 702, and the other end of the diversion elbow 702 is fixed to the upper end of the diversion straight pipe 703, and the middle part of the diversion straight pipe 703 is sealed and rotated in the central hole of the bottom pipe cover of the discharge pipe 4; the lower end of the diversion straight pipe 703 passes through to the bottom of the discharge pipe 4.

[0039] The diversion straight pipe 703 transports the matrix asphalt into the diversion elbow 702, and transports it to the annular spray pipe 701 through the diversion elbow 702, so that the matrix asphalt is sprayed out through multiple spray holes evenly arranged on the top surface of the annular spray pipe 701, which is beneficial to improve the offset mixing effect of the matrix asphalt and other materials.

[0040] The matrix asphalt spraying mechanism 7 also includes an inclined connecting rod 704 , one end of which is connected to the diversion elbow 702 , and the other end of which is connected to the mixing vertical shaft 501 .

[0041] When the mixing vertical axis 501 rotates, the diversion elbow 702 can be driven to rotate and circle through the inclined connecting rod 704, so that the diversion elbow 702 drives the diversion straight pipe 703 to rotate in a sealed manner in the central hole of the pipe cover at the bottom of the discharge pipe 4, so that the annular spray pipe 701 can rotate and spray, so that the spraying range is wider, which is more conducive to improving the contact effect with the asphalt modifier and other fixed reinforcement materials falling at different positions.

[0042] The matrix asphalt spraying mechanism 7 also includes a filter tube 705, the upper end of which is fixed to the lower end of the diversion straight pipe 703; the lower end of the filter tube 705 is inserted from top to bottom into the coaxially arranged annular liquid inlet box 706 and the insertion tube 707, and a liquid inlet chamber is provided between the annular liquid inlet box 706 and the filter tube 705, and the liquid inlet chamber is connected to the input pipe arranged on the side of the annular liquid inlet box 706; the filter tube 705 is inserted into the tube body of the annular liquid inlet box 706, and a plurality of strip filter holes are evenly arranged around it, so as to filter and screen the matrix asphalt entering from the liquid inlet chamber into the filter tube 705 through the plurality of strip filter holes; the outer tube surface of the filter tube 705 is slidably matched with the inner tube surface of the insertion tube 707.

[0043] The lower end of the filter tube 705 is inserted from top to bottom into the coaxially arranged annular liquid inlet box 706 and the insert tube 707. The filter tube 705 is inserted into the tube body of the annular liquid inlet box 706 and a plurality of strip filter holes are evenly arranged around it. The matrix asphalt first enters the liquid inlet chamber through the input pipe on the side of the annular liquid inlet box 706, and then can be filtered through the plurality of strip filter holes to prevent the entry of lumps in the matrix asphalt, which would result in low quality performance of the processed product. The filtered matrix asphalt can enter the diversion straight pipe 703 through the filter tube 705.

[0044] The base 2 includes an upper frame 201 fixed on the mixing barrel 1, and multiple pillars 202 are fixed at the lower end of the upper frame 201. The multiple pillars 202 slide in the shrink tube 203. A compression spring 204 is provided between each pillar 202 and the bottom surface of the shrink tube 203; the shrink tube 203 and the insertion tube 707 are both fixed on the lower frame 205.

[0045] The structural arrangement of the base 2 allows the feeding of the filter tube 705 to be stopped when the weight of the mixture in the mixing barrel 1 reaches a certain weight. When the mixture in the mixing barrel 1 gradually increases, the weight of the mixing barrel 1 and the mixture continues to increase, thereby driving the multiple pillars 202 to slide in the contraction tube 203 through the upper frame 201, compressing the multiple compression springs 204. At this time, the tube body with multiple strip filter holes at the lower end of the filter tube 705 gradually enters the insertion tube 707 from the annular liquid inlet box 706, thereby gradually blocking the multiple strip filter holes through the insertion tube 707, gradually reducing the feeding speed, and when the preset weight of the mixture is reached, the multiple strip filter holes are completely blocked, and the feeding is stopped at this time. After the mixing process is completed, the asphalt mixture is discharged and the feeding work is carried out again; a control valve is also provided on the diversion straight pipe 703, so as to close the diversion straight pipe 703 when discharging, open the discharge port on the side of the discharge pipe 4, and prevent the mixture from flowing into the filter tube 705.
