DETAILED DESCRIPTION

[0047] Example 1: Please refer to Figure 1-5 and Figure 7 In an embodiment of the present invention, a highway asphalt waste recycling and reuse device is provided, including a control center, a cutting module controlled by the control center, a separation module, a drilling module, and a blasting module, wherein the cutting module is used to construct a confined groove a and construct multiple first cutting grooves b and second cutting grooves c in the confined groove a, the separation module is used to separate along the confined groove a, the drilling module is used to drill at the intersection of the first cutting groove b and the second cutting groove c to form a blasting hole, and the blasting module is used to perform hydraulic blasting in the blasting hole.

[0048] The cutting module is any one or more of a handheld cutting machine, an automatic cutting machine, and a slotting machine;

[0049] The separation module is a double-layer separation plate, the double-layer separation plate has a gap, the gap is filled with a shock-absorbing structure, and the shock-absorbing structure is any one or more of a shock-absorbing spring and a shock-absorbing elastic pad.

[0050] The blasting module can be mounted on a double-layer partition board;

[0051] The drilling module is any one or more of a handheld drilling machine, an automatic drilling machine, and a pneumatic drilling machine;

[0052] The blasting module includes:

[0053] A plurality of mutually parallel guide rods 1, wherein the guide rods 1 are located directly above the first cutting groove 6 or directly above the second cutting groove c;

[0054] A guide sleeve 2, which is movably sleeved on the outside of the guide rod 1;

[0055] An adjusting chamber 3 is fixed below the guide sleeve 2;

[0056] A pressure rod 4 is embedded below the regulating chamber 3 and has a chamber;

[0057] A plurality of fracturing assemblies 5 distributed in the pressure rod 4 in an array along the axial direction of the pressure rod 4; and

[0058] The piston rod assembly 6 is slidably disposed in the regulating chamber 3 and can extend into the chamber of the pressure rod 4 to provide fracturing power for the fracturing assembly 5 .

[0059] In this embodiment, the recycling range of highway asphalt waste can be determined in advance by constructing the trench a. Then, the first cutting groove b and the second cutting groove c constructed in the trench a can divide the range planned by the trench a into areas. Then, the highway asphalt waste in each area can be processed independently by the drilling module and the blasting module, thereby reducing the impact of the asphalt recovery process in the trench a on the external highway.

[0060] In particular, the configured blasting module can perform small-scale extrusion blasting on the road surface, which can effectively reduce the impact on other road surfaces.

[0061] In this embodiment, the fracturing assembly 5 includes four wedge blocks 51 radially slidingly arranged in the pressure rod 4, and a fracturing block 52 is fixed to one end of the wedge block 51 away from the central axis of the pressure rod 4. A reset ring 8 is commonly connected between the four wedge blocks 51. The reset ring 8 is elastic and has a ring hole 81 in the middle. The wedge block 51 has a driving surface 53 and a stabilizing surface 54. The driving surface 53 is an inclined surface, and the stabilizing surface 54 is a vertical surface.

[0062] Wherein, the reset ring 8 is connected to the upper part of the wedge block 51;

[0063] During operation, when the rod 61 moves downward, the rod 61 first contacts the driving surface, thereby pushing the wedge 51 and the fracturing block 52 toward the outside of the pressure rod 4. During this process, the reset ring 8 is stretched, and the fracturing block 52 can generate a large squeezing force on the road asphalt during the outward movement, causing it to fracture obliquely upward.

[0064] As a preferred embodiment, a guide plate 7 is fixed to the outside of the pressure rod 4;

[0065] Under the limitation of the guide plate 7, the position point where the road asphalt is broken obliquely upward is guided outside the guide plate 7, which optimizes the position point where the road asphalt is broken obliquely upward and realizes complete blasting in a small range.

[0066] As a preferred embodiment, a guide layer is attached to the surface of the driving surface 53 so as to form an arc-shaped surface.

[0067] The curved surface can increase the impact acceleration of the fracturing block 52;

[0068] It should also be noted that, since the rod body 61 moves downward gradually, the multiple fracturing components 5 in the pressure rod 4 do not move simultaneously but move sequentially from top to bottom, so as to generate a greater squeezing force on the road asphalt layer by layer to cause it to fracture obliquely upward.

[0069] In this embodiment, the regulating chamber 3 includes:

[0070] The chamber body 31 is fixed below the guide sleeve 2, and the piston rod assembly 6 is sealed and slidably arranged inside the chamber body 31;

[0071] Oil hole 32, used for connecting to an external hydraulic controller;

[0072] At least two symmetrically arranged chutes 34 are provided in the housing 31 , and electromagnetic blocks 35 are embedded in the chutes 34 ; and

[0073] A clamping block 36 is slidably disposed in the sliding groove 34 and has a magnet disposed therein;

[0074] The pressing rod 4 is provided with a clamping slot 41 corresponding to the clamping block 36 .

[0075] When the blasting module is just lowered, the card block 36 can be used to lock the card slot 41 so that the pressure rod 4 can smoothly enter the blasting hole. The locking of the card block 36 on the card slot 41 can then be released. The locking and releasing of the card block 36 on the card slot 41 are both achieved by driving the card block 36 to slide, wherein the electromagnet 35 can realize the magnetic attraction and repulsion of the magnet, and during this process, the card block will slide accordingly.

[0076] In addition, the oil hole 32 is connected to an external hydraulic controller, and the external hydraulic controller can inject oil into the oil hole 32 to drive the piston rod assembly 6 to move downward.

[0077] The piston rod assembly 6 includes:

[0078] A rod body 61, one end of which is located in the chamber body 31 and the other end of which extends into the pressure rod 4, and a limited position straightening ring 67 is fixed on the rod body 61 extending into the pressure rod 4 for sliding connection with the pressure rod 4;

[0079] A pressing groove 62 fixed on the rod body 61;

[0080] A pressure plate 63 is sealingly and slidably disposed in the chamber body 31 and connected to the pressure groove 62 with an adjustable spacing using an anti-slip arm 65. A receiving groove 64 is formed between the pressure groove 62 and the pressure plate 63 for receiving the oil-gas mixture; and

[0081] A feeding pipe 66 is L-shaped, one end of which is connected to the receiving groove 64 and the other end extends from the rod 61. A valve body is provided in the feeding pipe 66;

[0082] The silo body 31 is provided with a through hole 33 corresponding to the feeding pipe 66 .

[0083] The external tube body can pass through the through hole 33 and be snapped into the feeding tube 66, so as to provide the fuel mixture into the feeding tube 66, wherein the fuel mixture includes fuel and oxygen;

[0084] As a preferred embodiment, the top of the pressure plate 63 is also connected to the adjustment chamber 3 by a return spring so as to determine the initial position of the piston rod assembly 6 and facilitate the positioning and connection of the external tube body to the through hole.

[0085] It should also be explained that after the piston rod assembly 6 gradually moves downward until it provides power to all the fracturing assemblies 5, the pressure groove 62 will drive the pressure rod 4 to move downward. During this process, the accommodating groove 64 will be compressed, thereby generating high temperature and causing the fuel mixture to explode, and then the back-impact pressure groove 62 will cause the pressure rod 4 to impact downward. At this time, the guide plate 7 and the fracturing assembly 5 will also impact downward, causing the multiple layers of cracked asphalt waste to be further squeezed and fractured.

[0086] A process for recycling and reusing waste highway asphalt, comprising the following steps:

[0087] S1. Use the cutting module to build a trench a on the road surface to be recycled.

[0088] S2 using the cutting module to construct a plurality of first cutting grooves b, second cutting grooves c in the surrounding groove a, a plurality of first cutting grooves b, second cutting grooves c constitute a grid;

[0089] S3. Using a drilling module for drilling and forming a blast hole at the intersection of the first cutting groove b and the second cutting groove c;

[0090] S4. Hydraulically blast the blasting module in the blasting hole to break the road surface in the trench a into a broken block shape.

[0091] S5. Recover the broken blocks.

[0092] Among them, by constructing the trench a, the recycling range of highway asphalt waste can be determined in advance. Afterwards, the first cutting groove b and the second cutting groove c constructed in the trench a can divide the area within the planned range of the trench a. Afterwards, the highway asphalt waste in each area can be processed independently through the drilling module and the blasting module, reducing the impact of the asphalt recovery process in the trench a on the external highway.

[0093] Example 2: Please refer to Figure 6 The difference from Example 1 is that the reset ring 8 is connected below the wedge block 51.

[0094] In fact, it is a more preferred embodiment to configure the reset ring 8 below the wedge block 51. When the reset ring 8 is configured below the wedge block 51, when the rod body 61 moves downward, the rod body 61 first contacts the driving surface, thereby pushing the wedge block 51 and the fracturing block 52 toward the outside of the pressure rod 4. During this process, the reset ring 8 is stretched and the annular ring is stretched at the same time. Moreover, since each fracturing assembly 5 is equipped with four wedge blocks 51, the annular ring can be evenly stretched, making it easier for the rod body 61 to pass through the annular ring without damaging it.

[0095] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
