Description

Technical Field

[0001] This invention belongs to the field of tire rubber graded particle processing technology, specifically relating to a waste tire rubber graded particle processing machine for vibratory mixing of colored asphalt pavement. Background Technology

[0002] Currently, vibration mixing technology and long-life colored asphalt pavement structures are being promoted and applied in China. In long-life colored asphalt pavement structures, to address the reflective cracking problem of semi-rigid base pavements, improvements have been made to the traditional semi-rigid base asphalt pavement. The base and subbase have been optimized with low-strength (less than 2.5 MPa) and ultra-low-strength (less than 2.0 MPa) cement-stabilized aggregates, minimizing reflective cracking. To address the issue of excessive strength difference between the asphalt surface layer and the semi-rigid base, and to prevent base cracks from reflecting back to the asphalt surface layer, a buffer layer is installed between them. This buffer layer uses rolled waste tire rubber granules (6cm), which are processed in the factory using waste tire rubber granules and waste rubber powder with a high-viscosity rubber agent.

[0003] Currently, there are no commercially available machines for processing waste tire rubber graded granules; stone processing machines or rubber powder processing machines are generally used. Since stone processing machines are primarily designed for hard materials, processing soft waste tire rubber results in poor granule shape and low efficiency. Rubber powder processing machines, on the other hand, fail to produce graded granules and produce excessive powder. To ensure the quality and production efficiency of waste tire rubber graded granule processing for improved semi-rigid base long-life colored asphalt pavement buffer layers, it is necessary to develop dedicated waste tire rubber graded granule processing machines.

[0039] The punching section consists of an inner template 45, an outer template 43, a tensioning mechanism 72, and a punching mechanism 73. The waste tire 44 is located between the inner template 45 and the outer template 43. The tensioning mechanism 72 is used to tighten the inner template 45 by driving multiple pairs of top rods 54 arranged in pairs. The punching mechanism 73 is used to punch the waste tire 44 by driving a square hollow cutter head 75 arranged on the cutter bar.

[0040] The shearing section consists of a translation mechanism, a support mechanism, a fixing mechanism 7, a conveying mechanism, and a shearing mechanism;

[0041] The translation mechanism is used to drive the inner template 45 and the punched waste tire 44 to move left and right by driving the card plate 56 on it to move left and right;

[0042] The support mechanism is used to adjust the overall width and diameter of the inner template 45 and provide support by driving multiple pairs of support rods 39 arranged in pairs to move and press against the inner template 45.

[0043] The fixing mechanism 7 is based on the outer template 43. The ends of the opening of the outer template 43 are respectively connected to the front plate 77 and the rear plate 78.

[0046] The grinding section includes a feed box 20, an upper grinding disc 29, and a lower grinding disc 31. The feed box 20 is connected to a feed cylinder, which is connected to the upper grinding disc 29. The grinding section is used to drive the upper grinding disc 29 to rotate, so as to grind the scrap material entering between the upper grinding disc 29 and the lower grinding disc 31 into rubber scraps.

[0047] For better results, in one embodiment, the vibratory mixing machine for processing waste tire rubber graded particles for colored asphalt pavement of the present invention includes a power system, which consists of an electric motor, a gearbox, a transfer case, a hydraulic motor, and a hydraulic pump. The power for the punching section, shearing section, and abrasive section is all provided by the power system.

[0048] For better results, in one embodiment, the inner template 45 is composed of multiple retractable arc-shaped plates, and the outer template 43 is composed of retractable arc-shaped plates; both the inner template 45 and the outer template 43 are provided with square punch holes 1, the size of which is consistent with the particle size of the rubber graded particles.

[0049] Furthermore, the inner template 45 consists of four retractable arc-shaped plates, as shown in the plan view. Figure 2 (a) Cross-sectional view is shown Figure 2 (b). From the plane Figure 2 (a) The inner template 45 is composed of two semi-circular convex and concave plates linked together, connected by a spring. Under the action of the tensioning mechanism 72, the inner template 45 can expand and contract into circles of different diameters to accommodate tires of different diameters. (From the cross-section...) Figure 2(b) The inner template 45 is composed of two arc-shaped convex and concave plates on the left and right, and the convex and concave plates are connected by springs. Under the action of the tensioning device 72, the inner template 45 can be stretched into rings of different widths to accommodate tires of different widths.

[0050] From the plane Figure 3 (a) The outer template 43 is composed of a semi-circular convex and concave plate linked together, connected by a spring; the front plate 77 connects to the convex plate, the rear plate 78 connects to the concave plate, and bolts connect the convex and concave plates. Springs are fitted onto the bolts, and rotating the nut allows the front plate 77 and rear plate 78 to move left and right under the action of the bolts, thus fixing and releasing the tires in the outer template. (From the cross-section) Figure 3 (b) The outer template 43 is composed of two arc-shaped convex and concave plates on the left and right, and the convex and concave plates are connected by springs. The rotating nut can move the front plate 77 and the rear plate 78 to the left and right under the action of the bolt. The outer template 43 can be stretched into rings of different widths to fix tires of different widths.

[0051] For better results, in one embodiment, the tensioning mechanism 72 includes a driving spur gear 66 that meshes with a driven spur gear 65. The driven spur gear 65 is coaxial with a driving bevel gear 71. The driving bevel gear 71 meshes with a driven bevel gear 64. The driven bevel gear 64 is mounted on a driven bevel gear shaft, which is connected to the push rod 54. The push rod 54 passes through the connecting plate 55 and is threadedly connected to it.

[0052] Furthermore, the push rods 54 are arranged in pairs, with 4-8 pairs of push rods 54 arranged on the entire circular surface. The push rods 54 are connected to the connecting plate 55 through threaded holes. The tail of the push rod 54 is connected to a concave half-shaft, and the convex half-shaft is connected to the driven bevel gear shaft. The concave half-shaft and the convex half-shaft mesh. By setting the concave half-shaft and the convex half-shaft, it is ensured that the push rod 54 can both rotate and move outward. The driven bevel gear 64 is mounted on the driven bevel gear shaft, and the driving bevel gear 71 is mounted on the driving bevel gear shaft 70. The driving bevel gear shaft 70 is coaxial with the driven circular gear shaft. The driven circular gear 65 is mounted on the driven circular gear shaft. The driving circular gear shaft 67 is mounted on the frame through bearings and bearing brackets, and the driving circular gear 66 is mounted on the driving circular gear shaft 67.

[0053] The working principle of the tensioning mechanism 72 is as follows: The hydraulic pump drives the active spur gear shaft 67 to rotate, which in turn drives the active spur gear 66 to rotate, which in turn drives the driven spur gear 65 to rotate, which in turn drives the driven spur gear shaft (active bevel gear shaft 70) to rotate, which in turn drives the active bevel gear shaft 70 (driven spur gear shaft) to rotate, which in turn drives the active bevel gear 71 to rotate, which in turn drives the driven bevel gear 64 to rotate, which in turn drives the driven bevel gear shaft to rotate, which in turn drives the convex half-shaft to rotate, which in turn drives the concave half-shaft to rotate, which in turn drives the push rod 54 to rotate. Simultaneously, the push rod 54 rotates and moves up and down under the action of the thread. The paired (double-row) push rods 54 press against the left and right arc-shaped convex and concave plates of the inner template 45, causing the two arc-shaped convex and concave plates to move to both sides, extending and retracting into rings of different widths to accommodate tires of different widths. The top rod 54 on the entire ring presses against the inner template 45, extending and retracting to form circles of different diameters to accommodate tires of different diameters.

[0054] For better results, in one embodiment, the punching mechanism 73 further includes a punching driven shaft 53 connected to the connecting plate 55. A punching driven spur gear 52 is provided on the punching driven shaft 53. The punching driven spur gear 52 meshes with a punching driving spur gear 68. The punching driving spur gear 68 is provided on the punching driving shaft 69.

[0055] Furthermore, sleeve 2 is mounted on the frame, square hollow cutter head 75 is fixed on the cutter bar, cutter bar spring 3 is sleeved on the cutter bar, and sleeve 2 acts as a guide, guiding the square hollow cutter head 75 to punch the waste tire 44. Push plate 4 is mounted on the cutter bar, camshaft 5 is mounted on the frame via bearings and bearing brackets, and cam 6 is mounted on camshaft 5. Punching driven shaft 53 is mounted on connecting plate 55, punching driven spur gear 52 is mounted on punching driven shaft 53, punching driven spur gear 52 meshes with punching driving spur gear 68, and punching driving spur gear 68 is mounted on punching driving shaft 69.

[0056] The working principle of the punching mechanism 73 is as follows: The entire machine connects the sleeves 2 of several punching devices 73 together to form a punching section. The hydraulic pump drives the camshaft 5 to rotate, which in turn drives the cam 6 to rotate. The rotation of the cam 6 causes the push plate 4 to move up and down, which in turn drives the square hollow cutter head 75 to move up and down, completing the punching of the waste tire 44 at this section. The hydraulic pump drives the punching drive shaft 69 to rotate, which in turn drives the punching drive gear 68 to rotate. Since the punching driven gear 52 meshes with the punching drive gear 68, the rotation of the punching drive gear 68 drives the punching driven gear 52 to rotate, which in turn drives the punching driven shaft 53 and the connecting plate 55 to rotate, which in turn drives the inner template 45, the waste tire 44, and the outer template 43 to rotate, aligning the next cutting section with the punching device 73 and completing the next punching. This cycle repeats until the waste tire 44 rubber is processed into the set grade granules.

[0057] The working principle of the punching section is as follows: The hydraulic pump drives the drive spur gear shaft 67 to rotate, which in turn drives the drive spur gear 66 to rotate, which in turn drives the driven spur gear 65 to rotate, which in turn drives the driven spur gear shaft (drive bevel gear shaft 70) to rotate, which in turn drives the drive bevel gear 71 to rotate, which in turn drives the driven bevel gear 64 to rotate, which in turn drives the driven bevel gear shaft to rotate, which in turn drives the convex half-shaft to rotate, which in turn drives the concave half-shaft to rotate, which in turn drives the push rod 54 to rotate. Simultaneously, the push rod 54 moves up and down under the action of the thread. The paired (double-row) push rods 54 press against the left and right arc-shaped convex and concave plates of the inner template 45, causing the two arc-shaped convex and concave plates to move to both sides, extending and retracting into rings of different widths to accommodate tires of different widths. The push rod 54 on the entire ring presses against the inner template 45, extending and retracting into circles of different diameters to accommodate tires of different diameters. A hydraulic pump drives the camshaft 5 to rotate, which in turn drives the cam 6 to rotate. The rotation of the cam 6 causes the push plate 4 to move up and down, which in turn drives the square hollow cutter head 75 to move up and down, completing the punching of the waste tire 44 at this section. The hydraulic pump drives the punching drive shaft 69 to rotate, which in turn drives the punching drive gear 68 to rotate. Since the punching driven gear 52 meshes with the punching drive gear 68, the rotation of the punching drive gear 68 drives the punching driven gear 52 to rotate, which in turn drives the punching driven shaft 53 and the connecting plate 55 to rotate, causing the inner template 45, the waste tire 44, and the outer template 43 to rotate, aligning the next cutting section with the punching device 73, completing the next punching. This cycle repeats continuously… processing the waste tire 44 rubber into the set grade of granules.

[0058] For better results, in one embodiment, the translation mechanism further includes a vertical plate 57 with a groove. The end of the locking plate 56 is connected to a slider that matches the groove. One end of the translation spring 62 is connected to the locking plate 56, and the other end is connected to the vertical plate 57.

[0059] Furthermore, the translation rack 60 is connected to the vertical plate 57, and the translation rack 60 meshes with the translation spur gear 58. The translation spur gear 58 is mounted on the translation spur gear shaft 59. The translation rack sleeve 61 is mounted on the frame, and the translation rack 60 is located inside the translation rack sleeve 61 and can slide left and right along it. The translation spur gear shaft 59 is mounted on the frame through bearings and bearing brackets.

[0060] The working principle of the translation mechanism is as follows: the hydraulic pump drives the translation spherical gear shaft 59 to rotate, the rotation of the translation spherical gear shaft 59 drives the translation rack 60 to move left and right, the left and right movement of the translation rack 60 drives the vertical plate 57 and the clamping plate 56 to move left and right, and the clamping plate 56 drives the inner template 45 and the punched waste tire 44 to move left and right.

[0061] For better performance, in one embodiment, the support mechanism includes a polygonal cam 42 and a support ring 37. The support rod 39 passes through the support ring 37 and has a rod cap 76 at its end. The rod cap 76 presses against the polygonal cam 42. A support spring 38 is provided on the support rod 39 between the rod cap 76 and the support ring 37.

[0062] Furthermore, the support rods 39 are arranged in pairs, with 4-8 pairs of support rods 39 arranged on the entire circular surface; the support ring 37 is a circular ring with rod holes, through which the support rods 39 pass. The support spring 38 is sleeved on the support rod 39, and the rod cap 76 is fixed to the top of the support rod 39. The polygonal camshaft 41 and the worm shaft are mounted on the frame via bearings and bearing brackets, and the polygonal cam 42 is mounted on the polygonal camshaft 41. The worm gear 51 is mounted on the polygonal camshaft 41 and meshes with the worm 50.

[0063] The working principle of the support device is as follows: the hydraulic pump drives the worm shaft to rotate, the rotation of the worm shaft drives the worm 50 to rotate, and since the worm wheel 51 meshes with the worm 50, the rotation of the worm 50 drives the worm wheel 51 to rotate, the rotation of the worm wheel 51 drives the polygonal cam shaft 41 to rotate, and the rotation of the polygonal cam shaft 41 drives the polygonal cam 42 to rotate; when the polygonal cam 42 rotates counterclockwise, the support rod 39 extends outward under the action of the polygonal cam 42 (the support spring 38 is compressed). When the support rod 39 is in contact with the inner template 45, the hydraulic pump stops driving, and the support of the inner template is completed under the self-locking action of the worm wheel 51 and the worm 50. When the polygonal cam 42 rotates clockwise, the support rod 39 retracts under the elastic force of the support spring 38, thus releasing its support for the inner template 45. The paired (double-row) support rods 39 press against the left and right arc-shaped convex and concave plates of the inner template 45, causing the two arc-shaped convex and concave plates to move to both sides, extending and retracting into rings of different widths to accommodate tires of different widths. The support rods 39 on the entire ring press against the inner template 45, extending and retracting into circles of different diameters to accommodate tires of different diameters.

[0064] For better results, in one embodiment, the fixing mechanism 7 includes a second cam 86 and a second push rod 79. Two second push rods 79 are provided and are respectively connected to the front plate 77 and the rear plate 78. The second cam 86 is in contact with the second push rod 79.

[0065] Furthermore, from the cross-section Figure 6 (b) The fixing mechanism 7 consists of two arc-shaped plates, a left plate, a right plate, bolts, nuts, and springs. It is connected by two arc-shaped convex and concave plates on the left and right, and the convex and concave plates are connected by springs. Rotating the nut can make the front plate 77 and the rear plate 78 move left and right under the action of the bolts. The outer template 43 can be extended and retracted into rings of different widths to fix tires of different widths.

[0066] The punched tire is located between the inner template 45 and the outer template 43, from the plane Figure 6 (a) The outer template 43 is an open plate, with the front plate 77 and the rear plate 78 connected to the two ends of the open plate respectively. The second cam 86 is mounted on the second camshaft 85, and the second camshaft 85 and the second sleeve 84 are mounted on the frame. The inner end of the second push rod 79 is connected to the front plate 77 and the rear plate 78, and the outer end is in contact with the second cam 86. The second sleeve 84 and the push rod spring 80 are sleeved on the second push rod 79.

[0067] The working principle of the fixing mechanism 7 is as follows: the hydraulic pump drives the second camshaft 85 to rotate, the rotation of the second camshaft 85 drives the second cam 86 to rotate, the rotation of the second cam 86 drives the second push rod 79 to move forward and backward, and drives the front plate 77 and the rear plate 78 to move forward and backward, thus completing the fixing and releasing of the waste tire 44 after punching and cutting from the inner template 45. When the cutter head 18 cuts the waste tire 44, the fixing device 7 fixes the waste tire 44 to the inner template 45. After the cutting is completed, the fixing device 7 releases the waste tire 44 from the inner template 45.

[0068] For better performance, in one embodiment, the conveying mechanism further includes a conveying hub 36, and the conveying hub ring 46 is connected to the conveying hub 36; the stud 47 is threadedly connected to the conveying hub ring 46, and the screw teeth 48 are threadedly connected to the stud 47.

[0069] Furthermore, the conveyor shaft 40 is mounted on the frame via bearings and bearing brackets. The conveyor hub 36 is mounted on the conveyor shaft 40, and the conveyor ring 46 is connected to the conveyor hub 36. The conveyor ring 46 has a threaded hole, and the stud 47 is located in the threaded hole of the conveyor ring 46, while the threaded tooth 48 is located in the threaded hole of the stud 47. The stud 47 and the threaded tooth 48 are provided with a threaded tooth handle 82 and a stud handle 83 at their tails. The size of the threaded tooth 48 is consistent with the particle size of the rubber granules. Rotating the stud handle 83 can raise or lower the stud 47, and rotating the threaded tooth handle 82 can raise or lower the threaded tooth 48.

[0070] The working principle of the conveying mechanism is as follows: rotating the stud handle 83 causes the stud 47 to fit against the inner template 45, and rotating the threaded handle 82 causes the threaded teeth 48 to extend to a suitable height, ensuring that the threaded teeth 48 can completely penetrate the punched holes of the waste tire 44. The hydraulic pump drives the conveying shaft 40 to rotate, which in turn drives the conveying hub 36 and the conveying ring 46 to rotate, which in turn drives the threaded teeth 48 to rotate, which in turn drives the inner template 45 and the punched waste tire 44 to rotate.

[0071] For better results, in one embodiment, the shearing mechanism further includes a double-sided rack 17, on which a left sprocket and a right sprocket 16 are respectively meshed and connected. The left sprocket and the right sprocket 16 are mounted on a gear carrier, which is connected to the cutter head 18.

[0072] Furthermore, each shearing device is equipped with two horizontal guide rails 9, and a transverse rack 10 is placed on the guide rails 9, which can slide forward and backward along the guide rails 9. The transverse rack 10 meshes with a transverse spur gear 12, which is mounted on a transverse spur gear shaft 13. The shaft bracket 11 is connected to the transverse spur gear shaft 13 via bearings. A longitudinal rack 14 is vertically arranged and fixed perpendicularly to the transverse rack 10. A longitudinal spur gear 15 meshes with the longitudinal rack 14 and is mounted on a longitudinal spur gear shaft, which is mounted on the frame via bearings and a bearing bracket.

[0073] A double-sided rack 17 is connected to a transverse spur gear shaft 11. A left spur gear and a right spur gear 16 mesh with the double-sided rack 17. The left spur gear is mounted on the left spur gear shaft 8, and the right spur gear 16 is mounted on the right spur gear shaft. A connecting rod connects the shafts of the left and right spur gears 16. The upper part of the connecting rod is connected to the tail of the cutter, and the cutter head 18 is located at the end of the cutter. The cutter head 18 is an arc-shaped cutter head, and its curvature matches the arc shape of the waste tire 44.

[0074] The working principle of the shearing mechanism is as follows: The hydraulic pump drives the transverse spur gear shaft 13 to rotate, which in turn drives the transverse spur gear 12 to rotate. Under the action of the transverse rack 10, the transverse spur gear 12 rotates and moves left and right along the transverse rack 10, which in turn drives the transverse spur gear shaft 13 to move left and right, which in turn drives the transverse spur gear shaft bracket 11 to move left and right, which in turn drives the double-sided rack 17, left spur gear, right spur gear 16, left spur gear shaft 8, right spur gear shaft, connecting rod, cutter, and cutter head 18 to move left and right as a whole, thereby adjusting the left and right position of the shearing. The hydraulic pump drives the longitudinal spur gear shaft to rotate, which in turn drives the longitudinal spur gear 15 to rotate. Since the longitudinal spur gear 15 meshes with the longitudinal rack 14, the rotation of the longitudinal spur gear 15 drives the longitudinal rack 14 to move forward and backward. The forward and backward movement of the longitudinal rack 14 drives the transverse rack 10 to move forward and backward along the guide rail 9, thereby realizing the forward and backward movement of the cutter head 18 and adjusting the forward and backward position of the cutter head 18. The hydraulic pump drives the left sprocket shaft 8 and the right sprocket shaft to rotate. The rotation of the left sprocket shaft 8 and the right sprocket shaft drives the left sprocket and the right sprocket 16 to rotate. Under the action of the double-sided rack 17, the left sprocket and the right sprocket 16 move up and down along the double-sided rack 17 while rotating, which drives the left sprocket and the right sprocket shaft bracket 11 and the connecting rod to move up and down, which in turn drives the cutter and the cutter head 18 to move up and down, thus completing the shearing work.

[0075] Working principle of the shearing section: See the cross-sectional diagram of the waste tire after punching and shearing (see diagram below). Figure 8 (a), see unfolded diagram. Figure 8 (b) After being punched and sheared, the waste tire 44 is serrated. The protruding parts are cut row by row to produce waste tire 44 rubber grade granules. The size of the granules is adjusted by the size of the square hollow cutter head 75.

[0076] Step 1: The hydraulic pump drives the translational spherical gear shaft 59 to rotate. The rotation of the translational spherical gear shaft 59 drives the translational rack 60 to move left and right. The left and right movement of the translational rack 60 drives the vertical plate 57 and the clamping plate 56 to move left and right. The clamping plate 56 drives the inner template 45 and the punched waste tire 44 to move to the right and enter the shearing system.

[0077] Step 2: The hydraulic pump drives the polygonal camshaft 41 to rotate, and the rotation of the polygonal camshaft 41 drives the polygonal cam 42 to rotate; when the polygonal cam 42 rotates counterclockwise, the support rod 39 extends outward under the action of the polygonal cam 42 (the support spring 38 is compressed), thus completing the support of the inner mold.

[0078] Step 3: The hydraulic pump drives the second camshaft 85 to rotate, the rotation of the second camshaft 85 drives the second cam 86 to rotate, and the rotation of the second cam 86 drives the front plate 77 and the rear plate 78 to move in opposite directions to complete the fixing of the punched waste tire 44 to the inner template 45.

[0079] Step 4: The hydraulic pump drives the conveyor shaft 40 to rotate, the conveyor shaft 40 rotates, the conveyor hub rotates, the conveyor hub rotates, the screw gear 48 rotates, and the screw gear 48 rotates, causing the inner template 45 and the punched waste tire 44 to rotate to the shearing position.

[0080] Step 5: The hydraulic pump drives the left and right sprocket shafts 8 and 16 to rotate. Under the action of the double-sided rack 17, the left and right sprocket shafts 8 and 16 move downwards along the rack 17, causing the left and right sprocket shaft supports and connecting rods to move downwards, thus moving the cutter and blade head 18 downwards, completing the first shearing operation and cutting the circular waste tire 44. The hydraulic pump then drives the left and right sprocket shafts 8 and 16 to reverse, raising the blade head 18 to its highest position.

[0081] Step 6: The hydraulic pump drives the second camshaft 85 to rotate, the rotation of the second camshaft 85 drives the second cam 86 to rotate, and the rotation of the second cam 86 drives the fixed block to move backward, so that the fixed waste tire 44 after punching is released from the inner template 45.

[0082] Step 7: The hydraulic pump drives the polygonal camshaft 41 to rotate, and the rotation of the polygonal camshaft 41 drives the polygonal cam 42 to rotate; when the polygonal cam 42 rotates clockwise, the support rod 39 retracts under the elastic force of the support spring 38, thus canceling the support for the inner template 45.

[0083] Step 8: The hydraulic pump drives the conveyor shaft 40 to rotate, the conveyor shaft 40 rotates and drives the conveyor hub to rotate, the conveyor hub rotates and drives the screw gear 48 to rotate, the screw gear 48 rotates and drives the inner template 45 and the first row of protrusions of the punched waste tire 44 to rotate to the shearing position.

[0084] Step 9: The hydraulic pump drives the polygonal camshaft 41 to rotate, and the rotation of the polygonal camshaft 41 drives the polygonal cam 42 to rotate; when the polygonal cam 42 rotates counterclockwise, the support rod 39 extends outward under the action of the polygonal cam 42 (the support spring 38 is compressed), thus completing the support of the inner mold.

[0085] Step 10: The hydraulic pump drives the second camshaft 85 to rotate, the rotation of the second camshaft 85 drives the second cam 86 to rotate, and the rotation of the second cam 86 drives the front plate 77 and the rear plate 78 to move towards each other to complete the fixing of the punched waste tire 44 to the inner template 45.

[0086] Step 11: The hydraulic pump drives the left and right sprocket shafts 8 and 16 to rotate. This rotation, in turn, causes the left and right sprockets 16 to rotate. Under the action of the double-sided rack 17, the left and right sprockets 16 move downwards along the rack, causing the left and right sprocket shaft supports 11 and the connecting rod to move downwards. This, in turn, causes the cutter and blade head 18 to move downwards, completing the shearing of the first row of protrusions. The hydraulic pump then drives the left and right sprocket shafts 8 and 16 to reverse, raising the blade head 18 to its highest position.

[0087] Repeat steps six through eleven to complete the cutting of the second, third, and subsequent rows of bumps.

[0088] For better results, in one embodiment, the grinding section further includes a pneumatic gear 26 and a grinding drive gear 27. The pneumatic gear 26 is disposed on the feed cylinder and meshes with the grinding drive gear 27. A hinge shaft 19 is disposed on the side wall inside the feed box 20. One end of the centrifugal rod 22 is connected to the hinge shaft 19, and the other end is connected to the centrifugal ball 21. The centrifugal ball 21 presses on the pressure plate 23. A spring stop bar 25 is disposed at the bottom inside the feed box 20. One end of the feed spring 24 is connected to the pressure plate 23, and the other end is connected to the spring stop bar 25.

[0089] Furthermore, the upper grinding disc 29 is connected to the upper grinding disc teeth at its lower part, and the grinding chip drive gear 27 is mounted on the grinding chip drive gear shaft 28. The grinding chip drive gear shaft 28 is mounted on the frame via bearings and bearing brackets. An observation port 34 and an observation port cover are provided on the upper grinding disc 29, and the lower grinding disc 31 is connected to the lower grinding disc teeth 30 at its upper part.

[0090] There is a discharge port between the upper grinding disc 29 and the lower grinding disc 31, and the receiving disc 74 is connected to the discharge port. The lifting plate 32 is located below the lower grinding disc 31, and the jack 33 is located below the lifting plate 32. The lifting plate 32 can be raised or lowered by adjusting the jack 33, and the spacing between the upper grinding disc teeth and the lower grinding disc teeth 30 can be adjusted to adjust the particle size of the rubber powder.

[0091] The working principle of the grinding system is as follows: Scrap material enters the feed cylinder from the feed box 20, and then enters the grinding zone between the upper and lower grinding disc teeth 30. A hydraulic pump drives the grinding drive gear shaft 28 to rotate, which in turn drives the grinding drive gear 27. Since the grinding drive gear 27 meshes with the paddle gear 26, its rotation drives the paddle gear 26, which in turn drives the upper grinding disc 29. Through the friction and shearing motion of the upper and lower grinding disc teeth 30, the scrap material is ground into rubber scraps. When the feed cylinder speed is low, the pressure plate 23 is at its highest position under the action of the feed spring 24. As the feed cylinder speed increases, the centrifugal force of the centrifugal ball 21 increases, and the centrifugal rod 22 moves downward along the hinge shaft 19, causing the centrifugal ball 21 to move downward, which in turn drives the pressure plate 23 downward. The downward movement of the pressure plate 23 accelerates the scrap material into the grinding zone between the upper and lower grinding disc teeth 30. The processing speed can be adjusted by changing the feed cylinder speed.

[0092] For better results, in one embodiment, the vibratory mixing and color asphalt pavement waste tire rubber graded particle processing machinery of the present invention also includes a control system, which consists of control elements, control software, operating switches, etc.

[0093] The control system can control the fixing of the inner and outer templates, tensioning of the inner template, punching speed, translation amount and translation speed, support of the inner template, fixing of the punched waste tires, conveying of the punched waste tires, shearing speed and shearing amount, and grinding speed.

[0094] In summary, the present invention relates to a vibratory mixing machine for processing waste tire rubber graded granules for colored asphalt pavement. The punching section comprises an inner template 45, an outer template 43, a tensioning mechanism 72, and a punching mechanism 73. The tensioning mechanism 72 drives multiple pairs of top rods 54 to move and tighten the inner template 45. The punching mechanism 73 drives a square hollow cutter head 75 mounted on a cutter bar to punch the waste tire 44. The shearing section comprises a translation mechanism, a support mechanism, a fixing mechanism 7, a conveying mechanism, and a shearing mechanism. The translation mechanism drives a clamping plate 56 to move left and right, causing the inner template 45 and the punched waste tire 44 to move left and right. The support mechanism drives multiple pairs of support rods 39 to move and tighten the inner template 45, adjusting the overall width and diameter of the inner template 45 to accommodate tires of different widths and diameters. The tire is supported; the fixing mechanism 7 is mainly based on the outer template 43, and the ends of the opening of the outer template 43 are respectively connected to the front plate 77 and the rear plate 78. The fixing mechanism 7 fixes the waste tire 44 to the inner template 45 by driving the front plate 77 and the rear plate 78; the conveying mechanism drives the conveying hub 46 to rotate to drive the inner template 45 and the punched waste tire 44 to rotate; the shearing mechanism drives the cutter head 18 on it to move to shear the waste tire 44; the grinding part is used to drive the upper grinding disc 29 to rotate to grind the scrap material entering between the upper grinding disc 29 and the lower grinding disc 31 into rubber shavings; through the cooperation of each mechanism, the vibrating mixing colored asphalt pavement waste tire rubber graded granule processing machine of the present invention can automatically process waste tires into rubber graded granules and rubber powder, with high waste tire utilization rate, no waste generated, and high production efficiency.
