[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0046] The following is based on Figure 1 - Figure 24 The asphalt milling material regeneration device provided by an embodiment of the present invention is described.

[0047] See also Figure 1 - Figure 10 The embodiment of the present invention provides a technical solution: an asphalt milling material recycling device, including an outer cylinder 3, which is rotatably mounted on a base 1. Specifically, a support wheel 2 is mounted on the base 1, and a roller 4 is fixed on the outer surface of the outer cylinder 3. The outer cylinder 3 is driven by an outer cylinder driving mechanism 5, and the outer cylinder driving mechanism 5 includes a first motor 51, a gear 52 and a ring gear 53, wherein the first motor 51 is mounted on the base 1, the gear 52 is connected to the output end of the first motor 51, the ring gear 53 is fixed to the outer circumferential surface of the outer cylinder 3, and the ring gear 53 is engaged with the gear 52. There is a certain inclination angle between the axis of the outer cylinder 3 and the horizontal plane, so that the material moves toward the lower side in the outer cylinder 3.

[0048] The asphalt milling material recycling device also includes a hollow shaft 10, which is limited to the inner center area of the outer cylinder 3. Specifically, the hollow shaft 10 is fixedly connected to the outer cylinder 3 through a fixing frame 37, and the axis of the hollow shaft 10 coincides with the axis of the outer cylinder 3. Preferably, the fixing frame 37 is composed of multiple cylindrical rods to reduce obstruction to material flow.

[0049] There is also a fixed cross bar 131 on the outside of the hollow shaft 10, and there is a reserved space between the fixed cross bar 131 and the outer circumferential surface of the hollow shaft 10. There are at least two fixed cross bars 131. Specifically, fixed vertical bars 13 are fixed on both sides of the fixed cross bar 131. The two ends of the fixed vertical bars 13 are respectively fixed to the surface of the hollow shaft 10 and the inner wall of the outer cylinder 3. The fixed cross bar 131 is located on the side of the fixed vertical bar 13 away from the hollow shaft 10. The fixed cross bar 131 and the fixed vertical bars 13 on both sides form a fixed frame structure. The plane where the fixed frame structure is located coincides with the axis of the hollow shaft 10.

[0050] Furthermore, the fixing vertical rod 13 can adopt the same structure as the cylindrical rod of the fixing frame 37 , so that the fixing vertical rod 13 can support the hollow shaft 10 and improve the stability of the fixing of the hollow shaft 10 .

[0051] A lifting plate 12 is also provided in the outer cylinder 3. There are multiple lifting plates 12, which are arranged in a circular matrix on the inner wall of the outer cylinder 3, thereby forming a group of lifting areas composed of multiple lifting plates 12. There is at least one lifting area, and at least one lifting area is arranged around the fixed cross bar 131. When the outer cylinder 3 rotates, the lifting plates 12 bring the material at the bottom of the outer cylinder 3 to a high place, and throw the material out at a high place to form a material curtain, thereby promoting the contact between the material and the hot air to improve the drying effect.

[0052] In addition, a swinging cross bar 141 is distributed between the two fixed cross bars 131. The swinging cross bar 141 has freedom in the circumferential direction of the hollow shaft 10. Preferably, the distance between the swinging cross bar 141 and the axis of the hollow shaft 10 is the same as the distance between the fixed cross bar 131 and the axis of the hollow shaft 10. Specifically, a swinging vertical bar 14 is fixed on both sides of the swinging cross bar 141, and a mounting ring 15 is rotatably provided on the outer circumference of the hollow shaft 10. The mounting ring 15 is located between the two fixed vertical bars 13, and the bottom end of the swinging vertical bar 14 is fixedly connected to the mounting ring 15. The swinging cross bar 141 and the swinging vertical bar 14 form a swinging frame structure, and the plane where the swinging frame structure is located coincides with the axis of the hollow shaft 10.

[0053] In addition, a chain net 16 is provided between the swing cross bar 141 and the fixed cross bar 131, one side of the chain net 16 is connected to the swing cross bar 141, and the other side of the chain net 16 is connected to the fixed cross bar 131. Since there is a fixed cross bar 131 on both sides of a single swing cross bar 141, two sets of chain nets 16 are connected to one swing cross bar 141, and the two sets of chain nets 16 are respectively connected to the fixed cross bars 131 on both sides. When the swing cross bar 141 is located at the midpoint of the line connecting the two fixed cross bars 131, the two sets of chain nets 16 connected to the swing cross bar 141 are in a semi-retracted state. At this time, when the swing cross bar 141 is rotated to a certain angle to either side around the axis of the hollow shaft 10, the chain net 16 on that side is in a fully retracted state, and the chain net 16 on the other side is in an extended state.

[0054] In addition, in order to drive the swing crossbar 141 to move, a traction rope group is also provided. A single traction rope group includes two traction ropes. The traction ropes can be steel wire ropes or ultra-high molecular weight polyethylene fiber ropes. The two traction ropes are respectively fixed between the fixed crossbar 131 and the swing crossbar 141. When one of the traction ropes is subjected to force, the swing crossbar 141 deflects toward the traction rope on that side, and the traction rope on the other side is released.

[0055] Specifically, for a single swing cross bar 141, the two traction ropes are the first traction rope 18 and the second traction rope 19. One end of the first traction rope 18 and the second traction rope 19 are fixedly connected to the swing cross bar 141, and the fixed point is preferably the end of the swing vertical bar 14 away from the hollow shaft 10. The first traction rope 18 moves with the fixed vertical bar 13 on one side of the swing vertical bar 14 as the support point, and the second traction rope 19 moves with the fixed vertical bar 13 on the other side of the swing vertical bar 14 as the support point, so as to facilitate pulling the swing cross bar 141 in two opposite directions through the first traction rope 18 and the second traction rope 19.

[0056] By pulling the first traction rope 18 and the second traction rope 19, the two chain nets 16 connected to the single swing cross bar 141 can be transformed between the retracted and extended states. When the material thrown out by the lifting plate 12 falls, it will be hindered by the chain net 16, which increases the falling time. When the chain net 16 changes from the retracted state to the extended state, it will also have the effect of throwing the material, thereby increasing the contact time between the material and the hot air, further improving the drying effect. At the same time, the chain net 16 will also deform and collide in the process of its own state change, thereby preventing the material from sticking to the chain net 16.

[0057] In this embodiment, multiple swing cross bars 141 can be provided, and the multiple swing cross bars 141 are arranged in a ring array around the hollow shaft 10. Correspondingly, corresponding to each swing cross bar 141, a fixed cross bar 131 and a traction rope group are provided to match it. As shown in the figure, three swing cross bars 141 are provided, and at this time, three groups of fixed cross bars 131 are also provided, and six groups of chain nets 16 are provided. The six groups of chain nets 16 surround the hollow shaft 10 to form a mesh surface, so that the chain nets 16 can continuously play a hindering role on the material. At this time, there are three groups of traction ropes to drive all the chain nets 16 to move. Of course, the swing cross bars 141 can also be set to more than three or less than three.

[0058] like Figure 10 - Figure 13 As shown, a first positioning member 25 is fixed on the outside of the fixed vertical rod 13, and a first guide member 251 is symmetrically installed on the first positioning member 25. A receiving cavity 132 is opened inside the fixed vertical rod 13, and the receiving cavity 132 is communicated with the interior of the hollow shaft 10. Correspondingly, a second through hole 133 is opened on the fixed vertical rod 13, and the second through hole 133 is communicated with the receiving cavity 132. A third through hole 252 is opened on the first positioning member 25, and the third through hole 252 is communicated with the second through hole 133. The first traction rope 18 and the second traction rope 1 9 changes direction through the first guide members 251 located on both sides of the first positioning member 25, and enters the accommodating cavity 132 through the third through hole 252 and the second through hole 133. Additional guide members can be provided at the connection between the accommodating cavity 132 and the second through hole 133 to facilitate the movement of the first traction rope 18 and the second traction rope 19. It should be noted that the first traction rope 18 and the second traction rope 19 here respectively enter the accommodating cavities in two different fixed vertical rods 13, and the two fixed vertical rods 13 are respectively located on both sides of the swinging vertical rod 14.

[0059] In addition, in order to prevent materials from entering the accommodating cavity 132 through the through hole and causing blockage, a rubber ring or a brush can be provided at the through hole of the first positioning member 25 to play a preventive role.

[0060] Optionally, two first guide members 251 located on a single side of the first positioning member 25 can be provided, one of which is closer to the mounting ring 15. The first traction rope 18 or the second traction rope 19 will first pass through the first guide member 251 closer to the mounting ring 15, and then change direction through the other first guide member 251 to enter the accommodating cavity 132. The purpose is to reduce the angle between the force direction of the first traction rope 18 or the second traction rope 19 and the radial direction of the mounting ring 15, thereby reducing the bending moment of the mounting ring 15 and improving the service life of the mounting ring 15.

[0061] And, combined with Figure 14 - Figure 16 A second positioning member 26 is also fixedly provided in the hollow shaft 10. The second positioning member 26 is provided at the connection point between the accommodating cavity 132 and the interior of the hollow shaft 10. A groove 262 is provided on the second positioning member 26. There are at least two grooves 262, which correspond to the accommodating cavity 132. A second guide member 261 is installed in each groove 262. The first traction rope 18 and the second traction rope 19 pass through the second guide members 261 in different grooves 262 respectively, and change direction through the second guide members 261 to extend along the hollow shaft 10.

[0062] And, combined with Figure 1 and Figure 2 A cover 8 is fixedly provided at one end of the hollow shaft 10, and a first through hole 81 is opened at the center of the cover 8. A third guide member 27 is provided on the surface of the cover 8 away from the hollow shaft 10 and at the edge of the first through hole 81. The first traction rope 18 and the second traction rope 19 are redirected and led out of the hollow shaft 10 through the third guide member 27, so that most of the traction rope group is placed in the accommodating cavity 132 and the hollow shaft 10 through the first guide member 251, the second guide member 261 and the third guide member 27, thereby avoiding long-term contact between the traction rope group and the material and improving the service life.

[0063] In this embodiment, the first guide member 251, the second guide member 261 and the third guide member 27 can be a guide tube, a guide block or a roller. In the figure, the first guide member 251, the second guide member 261 and the third guide member 27 are represented by rollers.

[0064] Combine Figure 16 、 Figure 17 , Figure 21 、 Figure 22 and Figure 23In order to drive the traction rope group to move so that the swing cross bar 141 swings back and forth, a traction rope driving mechanism is also provided. A mounting plate 9 is fixedly provided on the side of the cover 8 away from the hollow shaft 10. The mounting plate 9 is at a certain distance from the cover 8. The traction rope driving mechanism is installed on the mounting plate 9 and rotates synchronously with the outer cylinder 3. The traction rope driving mechanism includes a reciprocating rod 29. A support 35 is fixedly provided on the side of the mounting plate 9 close to the cover 8. The reciprocating rod 29 is supported by the support 35 and is slidably connected to the support 35. The axis of the reciprocating rod 29 is perpendicular to the axis of the hollow shaft 10, and the reciprocating rod 29 can move back and forth along its own axial direction, that is, the reciprocating rod 29 can move back and forth along the radial direction of the hollow shaft 10.

[0065] In addition, fasteners 36 are fixed at both ends of the reciprocating rod 29. The first traction rope 18 led out of the hollow shaft 10 is fixedly connected to the fastener 36 at one end of the reciprocating rod 29, and the second traction rope 19 led out of the hollow shaft 10 is fixedly connected to the fastener 36 at the other end of the reciprocating rod 29. When the reciprocating rod 29 moves, it pulls the first traction rope 18 and the second traction rope 19 to move.

[0066] Combine Figure 10 - Figure 20 The following is an exemplary description of a case where there are three swing cross bars 141:

[0067] On the basis of a swing crossbar 141 , a swing crossbar A42 and a swing crossbar B43 are further provided. The swing crossbar 141 , the swing crossbar A42 and the swing crossbar B43 are arranged at equal intervals around the axis of the hollow shaft 10 .

[0068] In addition, there are three groups of traction ropes at this time, namely the first traction rope 18 and the second traction rope 19 fixed on the swing cross bar 141, the first traction rope a38 and the second traction rope a39 fixed on the swing cross bar A42, and the first traction rope b40 and the second traction rope b41 fixed on the swing cross bar B43, wherein the first traction rope 18 and the second traction rope a39 enter the accommodating cavity 132 of the same fixed cross bar 131, the first traction rope a38 and the second traction rope b41 enter the accommodating cavity 132 of the same fixed cross bar 131, and the first traction rope b40 and the second traction rope 19 enter the accommodating cavity 132 of the same fixed cross bar 131.

[0069] At this time, three grooves 262 are provided on the second positioning member 26, and two second guide members 261 are provided in each groove 262. When the second guide member 261 is a roller, the two second guide members 261 are installed in the groove 262 through a rotating shaft. Since the traction ropes in the same groove 262 move in opposite directions, the directions of the two rollers are also opposite.

[0070] Furthermore, in order to facilitate the movement of multiple traction ropes in the hollow shaft 10, a first cable drum 20 and a second cable drum 21 are provided for sliding in the hollow shaft 10. The first cable drum 20 and the second cable drum 21 have a certain distance so that the two will not collide when sliding. The first traction rope 18, the first traction rope a38 and the first traction rope b40 are all fixed to one side of the first cable drum 20. The other side of the first cable drum 20 is fixed to a third traction rope 22. The third traction rope 22 is fixed to the fastener 36 on the reciprocating rod 29. The second cable drum 2 1 is provided with a through hole to facilitate the passage of the third traction rope 22. The first cable drum 20 is provided with multiple through holes. The second traction rope 19, the second traction rope a39 and the second traction rope b41 are fixed to one side of the second cable drum 21 after passing through the through holes. The fourth traction rope 23 is fixed to the other side of the second cable drum 21. The fourth traction rope 23 is fixed to another fastener 36 on the reciprocating rod 29, so that when the reciprocating rod 29 drives the first cable drum 20 and the second cable drum 21 to move closer to or away from each other, all the traction ropes can be driven to move.

[0071] Optionally, a single set of traction ropes can be symmetrically arranged on both sides of the swing cross bar 141 to balance the force on the swing cross bar 141. Two traction ropes with the same moving direction and close positions can be connected together through a U-shaped lock 24, and then the other end of the U-shaped lock 24 is connected to the first cable collection drum 20 or the second cable collection drum 21.

[0072] This exemplary description uses three swing bars 141 as a supplementary description and does not limit the number of the swing bars 141 .

[0073] Combine Figure 22 and Figure 23 The above-mentioned traction rope drive mechanism also includes a drive rod 28, which is fixed to the middle of the reciprocating rod 29. The length direction of the drive rod 28 is perpendicular to the axis of the reciprocating rod 29. A slide groove 281 is provided on the drive rod 28. A drive disk 31 is provided on the side of the drive rod 28 away from the hollow shaft 10. The drive disk 31 is rotatably connected to the mounting plate 9. A drive column 30 is fixed on the surface of the drive disk 31 near the drive rod 28. The drive column 30 is close to the circular edge of the drive disk 31. It can slide in the slide groove 281, so that when the driving disc 31 drives the driving column 30 to rotate, the driving column 30 can drive the reciprocating rod 29 to move back and forth. A driving shaft 32 is fixedly provided on the side of the driving disc 31 away from the driving column 30, and the driving shaft 32 is rotatably connected to the mounting plate 9. A second motor 33 is also provided on the side of the driving shaft 32 away from the driving disc 31. The second motor 33 is fixed on the mounting plate 9 and is used to drive the driving shaft 32 to rotate, thereby driving the reciprocating rod 29 to move through the second motor 33.

[0074] In this embodiment, in order to improve the stability of the movement of the driving rod 28, guide holes 282 can be opened at both ends of the driving rod 28, and two stabilizing rods 34 can be fixed on the mounting plate 9 so that the stabilizing rods 34 pass through the guide holes 282, so that the driving rod 28 is supported by the stabilizing rods 34 while moving.

[0075] Combine Figure 7 and Figure 8 In order to facilitate the installation of the chain net 16, a rotating connector 17 is sleeved on the outer circumference of the fixed cross bar 131 and the swing cross bar 141. The rotating connector 17 consists of a connecting plate 171 and a collar 172. There are multiple collars 172, and the multiple collars 172 are arranged at equal intervals. The multiple collars 172 are all fixedly connected to the connecting plate 171. During installation, one rotating connector 17 is installed on a fixed cross bar 131, and two rotating connectors 17 are installed on a swing cross bar 141. The collar 172 on one rotating connector 17 is inserted into the gap between the collar 172 on the other rotating connector 17, so that the two rotating connectors 17 have circumferential freedom, and the chain net 16 is fixedly connected to the connecting plate 171.

[0076] Combine Figure 8 and Figure 24 The chain network 16 is composed of multiple ring chains arranged at equal intervals. In order to avoid a large drop between adjacent ring chains during movement, which would cause the gaps in the chain network 16 to be too large, adjacent ring chains are connected by connecting columns 161, so that adjacent ring chains on the chain network 16 can only move within a certain range.

[0077] Combine Figure 1 - Figure 3 A feed cylinder 6 is provided between the traction rope driving mechanism and the outer cylinder 3. A feed port 61 is provided on the feed cylinder 6. The material can enter the feed cylinder 6 through the feed port 61 and then enter the outer cylinder 3. The feed cylinder 6 is fixed on the base 1, and the feed cylinder 6 is rotatably connected to the outer cylinder 3 and the cover 8.

[0078] In addition, a guide blade 11 can be set on the side of the outer cylinder 3 close to the feed cylinder 6. The guide blade 11 is spiral and multiple guide blades 11 are arranged around the axis of the outer cylinder 3. The guide blade 11 can promote the movement of materials into the outer cylinder 3.

[0079] Combine Figure 1 - Figure 3A discharge cylinder 7 is limited on the side of the outer cylinder 3 away from the feed cylinder 6, and a discharge port 71 is provided at the bottom of the discharge cylinder 7. The material in the outer cylinder 3 can be discharged from the discharge port 71. The discharge cylinder 7 is fixed on the base 1, and the discharge cylinder 7 is connected to the outer cylinder 3 for relative rotation. A hot air inlet 72 is provided on the surface of the discharge cylinder 7 away from the outer cylinder 3. The hot air inlet 72 is used to feed hot air into the outer cylinder 3. Specifically, a hot air furnace and a burner (not shown in the figure) can be installed at the hot air inlet 72.

[0080] When in use (working), the outer cylinder 3 rotates under the drive of the outer cylinder driving mechanism 5, and the hollow shaft 10, the chain network 16 and the traction rope driving mechanism all rotate synchronously with the outer cylinder 3. When the traction rope driving mechanism is started, the second motor 33 drives the driving disc 31 and the driving column 30 to rotate, and the driving column 30 drives the driving rod 28 to reciprocate along the radial direction of the outer cylinder 3 through the sliding groove 281. At this time, the reciprocating rod 29 and the driving rod 28 move synchronously, and the first traction rope 18 fixed at one end of the reciprocating rod 29 is pulled, and the second traction rope 19 fixed at the other end of the reciprocating rod 29 is released. Since the other ends of the first traction rope 18 and the second traction rope 19 are fixed on the swing cross bar 141, the swing cross bar 141 is deflected to one side, and then the chain net 16 on that side is transformed into a retracted state, and the chain net 16 on the other side is transformed into an extended state. When the reciprocating rod 29 moves to the other side, the first traction rope 18 is released and the second traction rope 19 is pulled, thereby deflecting the swing cross bar 141 to the other side, and then the chain nets 16 on both sides are transformed into opposite states. The second motor 33 continues to rotate, so that the above process is repeated.
