Description

Technical Field

[0001] This invention belongs to the field of asphalt concrete roll processing technology, specifically relating to vibration mixing and colored asphalt concrete roll processing machinery. Background Technology

[0002] Vibratory mixing solves the problem of uniformity in asphalt concrete mixing, and long-life pavement structures address the lifespan issue. However, ordinary vibratory mixers are designed and developed for ordinary black asphalt concrete and do not consider the special characteristics of colored asphalt concrete. Colored asphalt concrete differs from ordinary black asphalt concrete in three main aspects of its production process: the addition of pigments, the use of colored aggregates, and the replacement of ordinary black asphalt with colored asphalt. Currently, there is no dedicated colored asphalt concrete mixing machinery; ordinary black asphalt concrete mixers are still used. Producing colored asphalt concrete requires cleaning the mixing tank 75, replacing asphalt delivery pipes and nozzles, and even requiring the creation of a pigment addition device or manual pigment addition. This reduces production speed and makes the material proportions inaccurate. Since the production volume of colored asphalt pavement is limited, dedicating a mixer solely to colored asphalt concrete production is wasteful. Producing ordinary asphalt concrete requires cleaning the mixing tank 75 again, replacing asphalt delivery pipes and nozzles, significantly increasing the operating cost of the mixing plant, greatly reducing mixing output, and compromising quality.

[0003] To address the aforementioned issues, given the thinness of colored asphalt concrete pavement, this invention develops specialized production machinery to process the colored asphalt concrete pavement into rolls at the factory, which are then laid directly on the construction site. This improves construction speed, reduces mixing costs, and ensures construction quality. Summary of the Invention

[0047] For better results, in one embodiment, the vibratory mixing colored asphalt concrete roll processing machinery also includes a proportioning system, which consists of a computer, a data acquisition device, a wireless network, analysis and calculation software, etc.

[0048] The function of the proportioning system is to calculate the proportion, precise dosage, and feeding speed of each material by inputting the set output through analysis and calculation software, based on data acquisition, transmission, and storage. The analysis results are then transmitted to the control system, which issues operation instructions.

[0049] For better results, in one embodiment, the vibratory mixing colored asphalt concrete roll processing machinery also includes a power system, which consists of an electric motor 34, a gearbox 33, a transfer case 32, a hydraulic motor 31, and a hydraulic pump 30.

[0050] For better results, in one embodiment, the mixing section also includes a heating device 52, which is disposed around the single-stage aggregate mixing device 53. The heating device 52 consists of a heat insulation layer, a heating layer 62, and an electric heating element 63.

[0051] The mortar mixing device 5 can use commercially available mixing machinery; the function of the mortar mixing device 5 is to mix and stir the four raw materials—asphalt, mineral powder, pigment, and warm mix agent—in accordance with the proportions determined by the mixing system to produce colored warm mix asphalt mortar.

[0052] For better results, in one embodiment, the single-stage aggregate mixing device 53 includes an outer cylinder 48 and an inner cylinder 59. A partition 47 divides the outer cylinder 48 and the inner cylinder 59 into multiple mixing chambers 51. A vibrating mixing shaft 49 is provided in each mixing chamber 51, and mixing blades 61 are provided on the vibrating mixing shaft 49. An outer cylinder gear 64 is provided on the outer cylinder 48, and a spur gear 65 meshes with the outer cylinder gear 64. When the spur gear 65 rotates, it drives the outer cylinder 48 to rotate through the outer cylinder gear 64.

[0053] Furthermore, the feed inlet 60 is located at the top of the heating cylinder of the heating device 52, and the discharge outlet 67 is located at the bottom of the heating cylinder. The outer cylinder 48 and the inner cylinder 59 are both circular cylinders, forming a circular ring between them. The partition 47 divides the circular ring into several mixing chambers 51. The feed (discharge) gate 68 is located in the middle of the outer arc of the mixing chamber 51, and the gate switch 69 is controlled by the control system. The central shaft 50 is mounted on the frame via bearings and bearing brackets, and the driving spur gear 71 is mounted on the central shaft 50. The vibrating mixing shaft 49 is vibrating and located in the mixing chamber 51. The mixing spur gear 70 and the mixing blades 61 are mounted on the vibrating mixing shaft 49. The driving spur gear 71 meshes with the mixing spur gear 70. The outer cylinder gear 64 is mounted on the outer cylinder 48, and the spur gear shaft 66 is mounted on the frame via bearings and bearing brackets. The spur gear 65 is mounted on the spur gear shaft 66, and the outer cylinder gear 64 meshes with the spur gear 65.

[0054] The working principle of the single-stage aggregate mixing device 53 is as follows: the whole machine is generally equipped with 4 sets of single-stage aggregate mixing devices 53, and the number of single-stage aggregate mixing devices 53 used is selected according to the type of colored asphalt concrete. For example, CAC-13 colored asphalt concrete is composed of four types of single-grade colored aggregates: 10-15mm, 5-10mm, 3-5mm, and 0-3mm. Correspondingly, 10-15mm single-grade colored aggregate bins 54, 5-10mm single-grade colored aggregate bins 55, 3-5mm single-grade colored aggregate bins 1, and 0-3mm single-grade colored aggregate bins 3 are set up. Four sets of single-grade aggregate mixing devices 53 are required, with each set of single-grade aggregate mixing device 53 mixing one grade of colored aggregate. Similarly, CAC-10 colored asphalt concrete is composed of three types of single-grade colored aggregates: 5-10mm, 3-5mm, and 0-3mm, requiring three sets of single-grade aggregate mixing devices 53. CAC-5 colored asphalt concrete is composed of two types of single-grade colored aggregates: 3-5mm and 0-3mm, requiring two sets of single-grade aggregate mixing devices 53. Each single-grade aggregate mixing unit 53 adds single-grade stone and colored warm-mix asphalt mortar. The proportion and dosage of single-grade stone and colored warm-mix asphalt mortar are calculated and determined by the proportioning system. The computer analysis and calculation software calculates the mixing output of the mixture based on the set finished product output, then calculates the dosage of each type of single-grade stone and colored warm-mix asphalt mortar based on the set mix proportion, and finally calculates the dosage of single-grade stone and colored warm-mix asphalt mortar in each mixing bin 51.

[0055] Hydraulic pump 30 drives spur gear shaft 66 to rotate, which in turn drives spur gear 65 to rotate. Since spur gear 65 meshes with outer cylinder gear 64, the rotation of spur gear 65 drives the rotation of outer cylinder gear 64, which in turn drives the mixing chamber 51 to rotate. When the inlet (outlet) gate 68 is directly below the inlet 60, the control system controls gate switch 69 to open the inlet (outlet) gate 68, allowing the set weight of single-grade stone and colored warm-mix asphalt mortar to enter the mixing chamber 51 from the inlet 60. The control system then controls gate switch 69 to close the inlet (outlet) gate 68. Hydraulic pump 30 drives central shaft 50 to rotate, which in turn drives drive spur gear 71 to rotate. Since drive spur gear 71 meshes with mixing spur gear 70, the rotation of drive spur gear 71 drives the rotation of mixing spur gear 70, which in turn drives the vibrating mixing shaft 49 to rotate. The rotation of vibrating mixing shaft 49 drives the mixing blades 61 to rotate, thus mixing the single-grade stone and colored warm-mix asphalt mortar. While the mixture in the mixing chamber 51 is being mixed, the outer cylinder gear 64 rotates, which in turn drives the mixing chamber 51 to rotate. When the inlet (outlet) gate 68 is located directly above the outlet 67, the control system controls the gate switch 69 to open the inlet (outlet) gate 68. The mixed single-stage stone and colored warm-mix asphalt mortar enter the mixing device 46 from the outlet 67.

[0056] For better results, in one embodiment, the mixing device 46 includes a mixing drum 74 disposed on a three-stage mixing drive shaft 44. The mixing drum 74 is divided into multiple mixing cylinders 75. A curved three-stage mixing vibration mixing shaft 42 is disposed in each mixing cylinder 75. A three-stage mixing spur gear 36 and a three-stage mixing blade 41 are disposed on the curved three-stage mixing vibration mixing shaft 42. A three-stage mixing drive spur gear 38 is disposed on the three-stage mixing drive shaft 44. The three-stage mixing drive spur gear 38 meshes with the three-stage mixing spur gear 36.

[0057] Furthermore, the upper end of the feed pipe is connected to the outlet 67 of the single-stage aggregate mixing device 53, and the lower end is connected to the main feed pipe, which is a flexible pipe, with the lower end connected to the three-stage mixing inlet 73. The mixing drum 74 is mounted on the three-stage mixing drive shaft 44 via bearings, and the mixing drum 74 is divided into several mixing cylinders 75; the three-stage mixing inlet 73 is located at the upper part of the mixing cylinder 75, and the three-stage mixing outlet 76 is located at the lower part of the mixing cylinder 75. The curved three-stage mixing vibrating mixing shaft 42 adopts a vibrating structure and is located inside the mixing cylinder 75. The three-stage mixing spur gear 36 and the three-stage mixing blades 41 are mounted on the curved three-stage mixing vibrating mixing shaft 42. The three-stage mixing spur gear 36 meshes with the three-stage mixing drive spur gear 38, which is mounted on the three-stage mixing drive shaft 44. The three-stage mixing gear 36 meshes with the connecting gear 40. The discharge gear 78 and the connecting gear 40 are mounted on the connecting gear shaft 77. The discharge gear 78 meshes with the discharge cylinder gear 79, which is mounted on the outer wall of the mixing cylinder 74. The automatic discharge device 37 is located at the three-stage mixing outlet 76.

[0058] Furthermore, the automatic discharge device 37 consists of an outlet cover 83, a hinge shaft, a cover spring 85, a slide rail 84, a friction plate 82, a counterweight ball 87, and a support rod 86.

[0059] The outlet cover 83 is fixed to the bottom of the mixing tank 75 by a hinge. One end of the outlet cover spring 85 is connected to the outlet cover 83 and the other end is connected to the mixing tank 75. Under the elastic force of the outlet cover spring 85, the outlet cover 83 seals the mixing tank 75. The outlet cover 83, the slide 84, and the support rod 86 are arranged in a triangle. One end of the slide 84 is fixed to the outlet cover 83 and the other end is connected to the support rod 86. The other end of the support rod 86 is connected to the outlet cover 83.

[0060] Friction plate 82 is located within slide 84 near the outlet cover 83. The function of friction plate 82 is to fix counterweight ball 87, which is located within slide 84 and can slide left and right along slide 84. In the initial position, when the mixing cylinder 75 is at the top, counterweight ball 87 is fixed to the end near the outlet cover 83 by the friction plate 82. Under the elastic force of the outlet cover spring 85, the outlet cover 83 seals the mixing cylinder 75. When the mixing cylinder 75 rotates vertically downwards, the weight of counterweight ball 87 overcomes the friction force of friction plate 82 and slides diagonally downwards. When counterweight ball 87 reaches one end of support rod 86, because the weight of counterweight ball 87 is greater than the elastic force of outlet cover spring 85, the outlet cover 83 is opened, and the mixture enters the spreading and shaping system from the mixing cylinder 75. When the mixing cylinder 75 rotates to the top, counterweight ball 87 slides diagonally downwards within slide 84 under the action of gravity, and is fixed by friction plate 82 at the bottom.

[0061] The working principle of the mixing device 46 is as follows: the various single-grade stone materials and colored warm-mix asphalt mortar mixture after mixing enter the branch feed pipe from the discharge port 67 and then converge into the main feed pipe. It then enters the first mixing cylinder 75 of the mixing drum 74 through the three-mixing feed port 73. After the first mixing cylinder 75 reaches the set weight, it feeds the material to the second mixing cylinder 75. The hydraulic pump 30 drives the three-mixing drive shaft 44 to rotate. The rotation of the three-mixing drive shaft 44 drives the three-mixing drive gear 38 to rotate. Since the three-mixing drive gear 38 meshes with the three-mixing mixing gear 36, the rotation of the three-mixing drive gear 38 drives the three-mixing mixing gear 36 to rotate. The rotation of the three-mixing mixing gear 36 drives the three-mixing mixing gear shaft 39 to rotate. The rotation of the three-mixing mixing gear shaft 39 drives the three-mixing mixing blades 41 to rotate, thus mixing the mixture. Simultaneously, because the three-stage mixing gear 36 meshes with the connecting gear 40, the rotation of the three-stage mixing gear 36 drives the connecting gear 40 to rotate, which in turn drives the connecting gear shaft 77 to rotate. The connecting gear shaft 77 then drives the discharge gear 78. Since the discharge gear 78 meshes with the discharge cylinder gear 79, the rotation of the discharge gear 78 drives the discharge cylinder gear 79 to rotate, which in turn drives the mixing cylinder 75 to rotate. When the first mixing cylinder 75 rotates vertically downwards, the weight of the counterweight ball 87 overcomes the friction of the friction plate 82 and slides obliquely downwards. When the counterweight ball 87 reaches one end of the support rod 86, because the weight of the counterweight ball 87 is greater than the elastic force of the outlet cover spring 85, the outlet cover 83 is opened, and the mixture enters the spreading and shaping section from the mixing cylinder 75. Then the mixture from the second mixing cylinder 75 enters the spreading and shaping system, and so on, repeating the cycle to complete the mixing work.

[0062] The mixing principle of the heating and mixing system is as follows: Ordinary black asphalt mixing machines are of two types: continuous and intermittent. Due to the poor quality of aggregates in my country, continuous mixing machines cannot meet the mixing requirements due to their short mixing time, so intermittent mixing machines are commonly used in my country. Although intermittent mixing machines produce high mixing quality, they suffer from long mixing time, low efficiency, and high cost. This invention achieves the effect of an intermittent mixing machine through secondary screening, and simultaneously employs three-stage mixing, changing centralized mixing to progressively dispersed mixing. First, asphalt, mineral powder, pigments, and warm mix additives are mixed to produce colored warm mix asphalt slurry. Then, the colored warm mix asphalt slurry is mixed with single-grade aggregates to produce single-grade mixtures. Finally, the single-grade mixtures are mixed a third time to produce asphalt concrete. Continuous mixing is achieved through three-stage mixing without changing the total mixing time, greatly improving mixing efficiency and reducing mixing costs.

[0063] The third-stage mixing process utilizes a curved vibrating mixing shaft 42, whereas conventional mixing equipment uses a straight shaft. During operation, a linear velocity gradient exists from the shaft's center to the tip of the mixing blades, leading to variations in the uniformity of the mixture across different annular zones within the mixing drum. The area near the shaft center becomes an inefficient mixing zone. Since colored asphalt is a polymer material with strong intermolecular block and polymerization forces, resulting in poor flowability, this area is essentially a mixing blind zone. This invention employs a curved shaft and irregular mixing blades, dividing the mixing area into large and small zones in cross-section. The rotation of the curved shaft and irregular blades alternates between these zones, effectively addressing the inefficiency of the area near the shaft on a straight shaft and improving mixing quality.

[0064] For better results, in one embodiment, the spreading device includes flat gear beams 35 disposed on both sides of the mixing device 46. The flat gear beams 35 on the left and right sides are respectively slidably connected to a front horizontal flat gear 43 and a rear horizontal flat gear. The two ends of the three-stage mixing drive shaft 44 are respectively connected to the front horizontal flat gear 43 and the rear horizontal flat gear. The shaping device 11 includes a shaping flat gear 90, and a shaping spherical gear 88 is meshed with the shaping flat gear 90. The shaping flat gear 90 is connected to the scraper plate 93 through a connecting plate 92.

[0065] Furthermore, the front and rear transverse gears 43 and 44 are located on the side of the gear beam 35. The front and rear transverse gears 43 and 44 are connected to guide blocks and can slide left and right along the groove 72 of the gear beam 35. The front and rear ends of the three-mixing drive shaft 44 are fixed to the front and rear transverse gears 43 and 44 respectively via bearings and bearing brackets. The main feed pipe is fixed to the front transverse gear 43. The front transverse gear 43 meshes with the front spreading gear 45, and the rear transverse gear meshes with the rear spreading gear. The shafts 80 and 80 of the front spreading gear and the rear spreading gear are fixed to the frame respectively via bearings and bearing brackets. The spreading pipe 10 connects to the three-mixing outlet 76.

[0066] The working principle of the spreading device is as follows: the hydraulic pump 30 drives the front spreading spur gear shaft 80 and the rear spreading spur gear shaft to rotate synchronously, which in turn drives the front spreading spur gear 45 and the rear spreading spur gear to rotate synchronously. Since the front and rear horizontal gears mesh with the front and rear spreading spur gears respectively, the synchronous rotation of the front spreading spur gear 45 and the rear spreading spur gear drives the front horizontal gear 43 and the rear horizontal gear to slide left and right along the sliding groove 72 of the horizontal gear beam 35, which drives the mixing drum 74 and the main feed pipe to move left and right synchronously. The mixture is spread from the three mixing outlets 76 of the mixing drum 75 to the working platform 26 of the conveying system through the spreading pipe 10.

[0067] Furthermore, the shaping spur gear 88 of the shaping device 11 is mounted on the shaping spur gear shaft 89, and the shaping spur gear shaft 89 is fixed to the frame by bearings and bearing brackets. The shaping flat gear sleeve 91 is fixed to the frame, and the shaping spur gear 88 is inside the shaping flat gear sleeve 91 and can slide up and down along the shaping flat gear sleeve 91. The shaping spur gear 88 and the shaping flat gear 90 mesh, and the upper end of the connecting plate 92 is connected to the shaping flat gear 90 and the scraper plate 93 at the lower end.

[0068] The working principle of the shaping device 11 is as follows: the hydraulic pump 30 drives the shaping spherical gear shaft 89 to rotate, which in turn drives the shaping spherical gear 88 to rotate. The shaping spherical gear 88 meshes with the shaping flat gear 90. The rotation of the shaping spherical gear 88 drives the shaping flat gear 90 to slide up and down along the shaping flat gear sleeve 91, which in turn drives the connecting plate 92 and the scraper 93 to move up and down, thereby adjusting the working height of the scraper 93 and thus adjusting the loose paving height of the colored asphalt concrete. As the working platform 26 moves the mixture forward, it scrapes the mixture flat, completing the shaping work of the mixture.

[0069] For better performance, in one embodiment, the conveying device includes a toothed pulley 25 that meshes with the toothed belt 95, and the working platform 26 is composed of a support plate 27 disposed on the toothed belt 95.

[0070] Furthermore, a toothed pulley 25 is mounted on a toothed pulley shaft 94, which is fixed to the frame by bearings and bearing brackets. A support plate 27 is mounted on a toothed belt 95. The support plate 27 is placed on a crossbeam 28 and can slide on it. The crossbeam 28 is vertically connected to a column 29. Supported by the crossbeam 28, the support plate 27 forms a working platform 26, on which material spreading, shaping, and compaction operations are completed.

[0071] The working principle of the conveying device is as follows: Due to the high resistance during the processing and conveying of colored asphalt concrete rolls 15, ordinary belts and pulleys lack sufficient friction. Therefore, this invention employs a toothed belt 95 and a toothed pulley 25. A hydraulic pump 30 drives the toothed pulley shaft 94 to rotate, which in turn drives the toothed pulley 25 to rotate. The rotation of the toothed pulley 25 causes the toothed belt 95 to move horizontally, which in turn drives the support plate 27 to move forward. The support plate 27 forms a working platform 26, which is placed on a crossbeam 28 and can slide on it, bearing various impact forces during material spreading, shaping, and compaction operations. The forward movement of the working platform 26 completes the conveying work.

[0072] For better results, in one embodiment, the width adjustment device includes an adjustment plate 96 and an adjustment spur gear 99. The adjustment plate 96 is disposed on both sides of the upper part of the working platform 26, and the adjustment spur gear 99 is meshed with an adjustment flat gear 97, which is connected to the adjustment plate 96.

[0073] Furthermore, the function of the adjusting plate 96 is to adjust the working width, i.e. the width of the finished roll material. The adjusting plate 96 is connected to the adjusting flat gear 97, which meshes with the adjusting spur gear 99. The adjusting spur gear shaft 98 is fixed on the machine frame through bearings and bearing brackets. The adjusting spur gear 99 is installed on the adjusting spur gear shaft 98. The adjusting flat gear sleeve 100 is installed on the machine frame. The adjusting flat gear 97 is located inside the adjusting flat gear sleeve 100 and can slide left and right along the adjusting flat gear sleeve 100.

[0074] The working principle of the width adjustment device is as follows: the hydraulic pump 30 drives the adjusting spur gear shaft 98 to rotate, the rotating adjusting spur gear shaft 98 drives the adjusting spur gear 99 to rotate, and since the adjusting flat gear 97 meshes with the adjusting spur gear 99, the rotating adjusting spur gear 99 drives the adjusting flat gear 97 to move back and forth along the adjusting flat gear sleeve 100, which in turn drives the adjusting plate 96 to move back and forth, thereby realizing the adjustment of the width of the finished roll material.

[0075] For better results, in one embodiment, the compaction section further includes an initial compaction device 12 and a flat compaction device 13. The initial compaction device 12 consists of a moving plate, a fixed plate, a hinge shaft, and a crank-connecting rod structure. The moving plate and the fixed plate are connected by the hinge shaft, and the fixed plate is fixed to the frame. The height of the moving plate is adjustable, and the set initial compaction thickness is adjusted by adjusting the moving plate. The initial compaction is achieved by the reciprocating motion of the moving plate up and down through the crank-connecting rod structure. The flat compaction device 13 can be a common flat vibratory compaction machine, and ready-made machines are available on the market.

[0076] For better results, in one embodiment, the vibratory compaction device 14 further includes a hub 102 and a drive shaft 103 disposed within the vibratory wheel 101.

[0077] Furthermore, hub 102 is mounted on vibrating wheel 101, drive shaft 103 is mounted on hub 102 via bearings, drive sprocket 104 and second sprocket 112 are mounted on drive shaft 103, drive sprocket 104 meshes with vibrating sprocket 105, vibrating sprocket 105 is mounted on vibrating shaft 107, vibrating shaft 107 is mounted on vibrating frame 106 via bearings, and an offset block is mounted on vibrating shaft 107. Second sprocket 112 meshes with external sprocket 110, external sprocket 110 is mounted on external sprocket shaft 109; external sprocket 110 meshes with internal gear 111, internal gear 111 is mounted on vibrating wheel 101.

[0078] The working principle of the vibratory compaction device 14 is as follows: The hydraulic pump 30 drives the drive shaft 103 to rotate, which in turn drives the drive sprocket 104 to rotate. Since the drive sprocket 104 meshes with the vibrating sprocket 105, the rotation of the drive sprocket 104 drives the vibrating sprocket 105 to rotate, which in turn drives the vibrating shaft 107 to rotate. The rotation of the vibrating shaft 107 drives the eccentric block 108 to rotate, and the rotation of the eccentric block 108 generates an alternating excitation force to compact the mixture. The hydraulic pump 30 drives the drive shaft 103 to rotate, which in turn drives the second sprocket 112. Since the second sprocket 112 meshes with the outer sprocket 110, the rotation of the second sprocket 112 drives the outer sprocket 110 to rotate. Since the outer sprocket 110 meshes with the inner gear cylinder 111, the rotation of the outer sprocket 110 drives the inner gear cylinder 111 to rotate, and the rotation of the inner gear cylinder 111 drives the vibrating wheel 101 to rotate.

[0079] For better results, in one embodiment, the extrusion device 18 further includes a second slide groove 114, in which a push spring 115 and an upper wheel shaft 116 are disposed. The push spring 115 is located below the upper wheel shaft 116. The upper wheel 17 and the lower wheel 16 are located above and below the material after vibration and compression, respectively.

[0080] Furthermore, to reduce the damage to the colored asphalt concrete surface caused by the metal wheels, high-strength rubber wheels are used for the upper wheel 17 and lower wheel 16, increasing flexibility while maintaining high strength. The upper wheel 17 and lower wheel 16 are respectively mounted on the upper wheel axle 116 and lower wheel axle 113, with the lower wheel axle 113 mounted on the frame via bearings. The lower wheel axle 113 is a fixed wheel, while the upper wheel axle 116 is a movable axle. The thickness of the colored asphalt concrete surface is adjusted by adjusting the main height of the upper wheel axle 116 to adjust the distance between the upper wheel 17 and lower wheel 16. A second slide groove 114 is provided on the frame, with the push spring 115 and the upper wheel axle 116 located within it. The push spring 115 is below the upper wheel axle 116. The push plate 117 is in contact with the upper wheel axle 116, and the upper end of the hydraulic push rod 118 is connected to the hydraulic cylinder 119, while the lower end is connected to the push plate 117. The hydraulic cylinder 119 can drive the hydraulic push rod 118 and the push plate 117 to move up and down, and drive the upper wheel shaft 116 to move up and down in the second slide groove 114, so as to realize the adjustable gap between the upper wheel 17 and the lower wheel 16.

[0081] The working principle of the extrusion device 18 is as follows: the hydraulic pump 30 drives the upper wheel shaft 116 and the lower wheel shaft 113 to rotate, and the rotation of the upper wheel shaft 116 and the lower wheel shaft 113 drives the upper wheel 17 and the lower wheel 16 to rotate. After initial pressing, flat pressing and vibration compaction, the colored asphalt concrete is conveyed to the right on the working platform 26 and enters the upper wheel 17 and the lower wheel 16 to complete the extrusion. The gap between the upper wheel 17 and the lower wheel 16 is adjusted by the hydraulic cylinder 119 to adjust the thickness of the final product.

[0082] For better results, in one embodiment, the vibratory mixing colored asphalt concrete roll processing machinery also includes a cooling system 19, which consists of a refrigeration unit 20, a cooling chamber, an air inlet, an air outlet, and a control switch. The function of the cooling system 19 is to reduce the temperature of the compacted colored asphalt concrete from around 120 degrees Celsius to below 40 degrees Celsius through the cooling chamber.

[0083] For better results, in one embodiment, the cutting device 56 includes a double-sided flat gear 126, with a left spur gear 125 and a right spur gear meshing on its left and right sides respectively. The left spur gear 125 and the right spur gear are rotatably mounted on the left shaft frame 122 and the right shaft frame respectively. A connecting plate 121 connects the left shaft frame 122 and the right shaft frame, and the cutter 120 is connected to the connecting plate 121.

[0084] Furthermore, the upper flat gear 130 is mounted on the frame and meshes with the upper spur gear 128. The upper spur gear 128 is mounted on the upper spur gear shaft 127. The shaft bracket 129 is mounted on the upper spur gear shaft 127 via bearings. The upper end of the double-sided flat gear 126 is connected to the shaft bracket 129. The two sides of the double-sided flat gear 126 mesh with the left spur gear 125 and the right spur gear, respectively. The left spur gear 125 and the right spur gear are mounted on the left spur gear shaft 124 and the right spur gear shaft, respectively. The left shaft bracket 122 and the right shaft bracket are connected to the left spur gear 125 and the right spur gear, respectively, via bearings. The connecting plate 121 connects the left shaft bracket 122 and the right shaft bracket. The cutter 120 is mounted on the connecting plate 121. The pad plate 57 is mounted on the pad plate leg 58.

[0085] The working principle of the cutting device 56 is as follows: the hydraulic pump 30 drives the upper spur gear 128 to rotate. Since the upper flat gear 130 meshes with the upper spur gear 128, the upper spur gear 128 rotates under the action of the upper flat gear 130, while the upper spur gear shaft 127 moves left and right, which drives the shaft frame 129 to move left and right. The shaft frame 129 drives the double-sided flat gear 126, the left spur gear 125, the right spur gear and the connecting plate 121 to move left and right. The left and right movement of the connecting plate 121 drives the cutter 120 to move left and right, adjusting the position of the cutter 120 in the horizontal direction. The hydraulic pump 30 drives the left sprocket 125 and the right sprocket to rotate. Since the double-sided flat gear 126 meshes with the left sprocket 125 and the right sprocket on both sides respectively, under the action of the double-sided flat gear 126, the left sprocket 125 and the right sprocket rotate, and at the same time, the left sprocket shaft 124 and the right sprocket shaft move up and down, driving the left shaft bracket 122 and the right shaft bracket to move up and down, driving the connecting plate 121 to move up and down, and finally driving the cutter 120 to move up and down, completing the cutting of the colored asphalt concrete pavement panel under the support of the pad plate 57.

[0086] For better results, in one embodiment, the winding device 24 further includes a winding power shaft 23 and a winding driven shaft 137. The winding spindle 131 has recesses 132 at both ends, and both the winding power shaft 23 and the winding driven shaft 137 have protrusions 133 at their ends, with the recesses 132 and protrusions 133 fitting together. The winding driven shaft 137 passes through and is slidably connected to a guide plate 136. An inner plate 134 is connected to the guide plate 136, and an outer plate 140 is connected to the tail of the winding driven shaft 137. A second spring 135 connects the inner plate 134 and the outer plate 140. One end of the second push rod 138 is connected to the outer plate 140, and the other end is connected to a second hydraulic cylinder 139.

[0087] Furthermore, the winding power shaft 23 is mounted on the frame via bearings and bearing brackets, the guide plate 136 is mounted on the frame, and the second spring 135 mainly serves as a safety device to prevent the spindle 131 from falling off when the hydraulic cylinder 119 malfunctions, so that the protrusion 133 of the winding driven shaft 137 is always engaged with the concave block 132 of the spindle 131.

[0088] The working principle of the coiling device 24 is as follows: the second hydraulic cylinder 139 drives the second push rod 138 to move outward, which in turn moves the outer plate 140 and the coiling driven shaft 137 to the set position, hoisting the coil 131 to the middle position of the coiling power shaft 23 and the coiling driven shaft 137, keeping the height of the concave block 132 of the coil 131 consistent with the height of the convex block 133. The second hydraulic cylinder 139 drives the second push rod 138 to move inward, which in turn moves the outer plate 140 and the coiling driven shaft 137 inward, so that the convex block 133 at the inner end of the coiling power shaft 23 and the coiling driven shaft 137 enters the concave block 132 at both ends of the coil 131. The hydraulic pump 30 drives the coiling power shaft 23 to rotate, which in turn rotates the coil 131, rolling the colored asphalt concrete pavement slab onto the coil 131.

[0089] For better results, in one embodiment, the rolling section also includes a release film conveying device 21. To prevent the layers of the colored asphalt concrete pavement roll from sticking together, release films 22 are placed between the layers. The release film conveying device 21 conveys the release films 22 into the colored asphalt concrete pavement roll. The release film conveying device 21 is essentially similar to the rolling device 24. During use, the concave and convex blocks of the release film roll are engaged, and the rolling device 24 and the release film conveying device 21 rotate synchronously to complete the final process of the colored asphalt concrete pavement roll material.

[0090] For better results, in one embodiment, the vibratory mixing colored asphalt concrete roll processing machinery also includes a control system, which consists of control elements, control software, operating switches, etc.

[0091] The control system can control the operation of the feeding, screening and storage section, proportioning system, mixing section, spreading and shaping section, conveying section, compaction section, cooling system 19, and rolling section. It can also adjust the feeding and screening speed, control the proportion and usage of various materials, adjust the heating temperature and mixing speed, control the feeding and discharging, adjust the spreading speed and loose spreading height, control the forward speed of the working platform 26, adjust the compaction speed and compaction force, control the cooling speed and air intake, and adjust the rolling speed, etc.

[0092] The vibratory mixing and colored asphalt concrete roll processing machinery of the present invention has the following characteristics:

[0093] (1) The present invention processes colored asphalt concrete pavement into rolls in the factory and lays the rolls directly on the construction site, which can improve the construction speed, reduce the mixing cost, and ensure the construction quality.

[0094] (2) Ordinary black asphalt mixing plants are of two types: continuous and intermittent. Due to the poor quality of aggregates in my country, continuous mixing plants cannot meet the mixing requirements due to their short mixing time. Therefore, intermittent mixing plants are commonly used in my country. Although intermittent mixing plants produce high-quality aggregates, they suffer from long mixing times, low efficiency, and high costs. They are suitable for on-site mixing but not for factory production. This invention adopts a three-stage mixing process, changing centralized mixing to progressively decentralized mixing. First, asphalt, mineral powder, pigments, and warm mix additives are mixed to form colored warm mix asphalt slurry. Then, the colored warm mix asphalt slurry is mixed with single-grade aggregates to form single-grade mixtures. Finally, the single-grade mixtures are mixed to form asphalt concrete. Continuous mixing is achieved through three-stage mixing without changing the total mixing time, greatly improving mixing efficiency and reducing mixing costs.

[0095] (3) The curved vibrating mixing shaft 42 of the third-stage mixing uses a curved shaft, while ordinary mixing equipment uses a straight shaft. During operation, there is a linear velocity gradient from the center of the shaft to the tip of the mixing blades 61, which will cause differences in the uniformity of the mixture on different annular belts in the mixing drum. The area near the shaft center becomes a low-efficiency mixing area. Since colored asphalt is a polymer material with large intermolecular block and polymerization forces and poor fluidity, the area near the shaft center is basically a blind zone for mixing. This invention uses a curved shaft and irregular mixing blades 61, which divides the mixing area into large and small areas from the cross-section. After the curved shaft and irregular mixing blades 61 rotate, the mixture in the large and small areas rotates intermittently, solving the problem that the area near the shaft center of the straight shaft is a low-efficiency mixing area and improving the mixing quality.

[0096] (4) All stirring shafts adopt a vibrating structure to achieve vibration mixing throughout the process.

[0097] In summary, the vibratory mixing colored asphalt concrete roll processing machinery of the present invention includes a mixing section, a spreading and shaping section, a conveying section, a compaction section, and a roll forming section. The mixing section includes a slurry mixing device 5, a single-grade aggregate mixing device 53, and a mixture mixing device 46.

Multiple sets of single-grade aggregate mixing devices 53 are provided to mix different grades of single-grade aggregate with the colored warm-mix asphalt slurry. The mixture mixing device 46 mixes the single-grade mixtures after mixing by each single-grade aggregate mixing device 53. The spreading and shaping section includes a spreading device and a shaping device 11. The spreading device spreads the material mixed by the mixture mixing device 46 onto the working platform 26 of the conveying section through a spreading pipe 10. The shaping device 11 levels the material conveyed to the working platform 26 using a scraper 93. The conveying section includes a conveying device and a width adjustment device.
