Description

Technical Field

[0001] The invention relates to a recycling and crushing device for asphalt recycled materials, belonging to the technical field of asphalt recycled materials processing equipment. Background Art

[0002] Existing asphalt pavement recycling mostly refers to old asphalt pavements that cannot meet the pavement performance requirements. The old asphalt mixture is recovered by milling or digging, and then a certain amount of regeneration agent, additives, new aggregate and new asphalt are added for mixing, and then used again in road construction technology. Therefore, the efficient recycling of waste asphalt pavement aggregates has important practical significance.

[0003] In the process of processing asphalt recycled materials, it is necessary to first crush the old asphalt blocks. The existing old asphalt blocks are crushed by a shredder. However, since the specifications and shapes of the whole old asphalt blocks are different, it is difficult for the biting end of the shredder to directly tear the whole old asphalt block efficiently. It is necessary to repeatedly find the biting convex points of the old asphalt block. In order to adapt to the biting end of the shredder, the old asphalt block must be knocked into small pieces first, and then put into the shredder for shredding, which is troublesome to operate. In view of the above shortcomings, the present invention proposes a recycling and crushing equipment for asphalt recycled materials. Summary of the invention

[0011] A further improvement is that a left oblique discharge channel is formed between the discharge oblique section and the upper concave discharge edge.

[0012] A further improvement is that the vertical height between the top surface of the material box bottom plate and the top surface of the planer board body is 1.5-2.5 cm.

Through the planing device, the asphalt blocks after the layers are planed are vertically aligned for feeding under the diversion effect of the feed hopper before flowing into the biting end of the shredder, so that the biting end of the shredder can directly perform the crushing operation, and there is no need to directly feed the whole old asphalt block like the shredder in the prior art. Because the old asphalt block raw materials are of different specifications and shapes and are not suitable for the biting end of the shredder, it is necessary to repeatedly find the biting convex points of the old asphalt block, thereby solving the problems of great crushing difficulty and low efficiency of the existing shredder.

An inward-retracting slider 524 is longitudinally connected to the left end of each of the stabilizing slide bars 522. A discharging inclined section 525 is provided on the left side of the inward-retracting slider 524. When the inward-retracting slider 524 is pushed to slide to the left by each spring 523, a discharging inclined section 525 and the left side of the triangular protrusion 511 form a discharging slope surface.

[0042] The knocking assembly 9 includes a knocking seat 91 , and a rotator 92 is longitudinally arranged at the rear end of the knocking seat 91 , and a swing arm 93 is transversely arranged on the rotator 92 , and a pressing head 94 is arranged on the left top surface of the swing arm 93 .

[0043] Working principle:

[0044] First, the old asphalt blocks are transported into the box body 21 through the first conveyor belt. When a certain amount of material is loaded into the material cavity 22, it is compacted by the pressing head 94 on the knocking assembly 9, and then the crushing operation of the equipment can be carried out. First, the hydraulic telescopic device 8 is extended to the right to push the sliding bottom plate group 3, the planing board assembly 4, the feed hopper 6 and the shredder 7 to slide horizontally to the right in the bottom plate slide 12. During this process, the planing board body 42 will pass through the planing board opening 23 from left to right into the lower end of the cavity of the box body 21 to plan the old asphalt blocks into layers with a thickness of 2 cm, and the planed asphalt layer will be formed between the discharge oblique section 33 and the upper concave discharge edge 43. It is discharged into a left oblique discharge channel, and is directed vertically downward through the feed hopper 6 to the biting end of the shredder 7 for rapid crushing. Since the thickness of the planed asphalt layer will not be greater than 2 cm, the shredder 7 does not need to repeatedly search for the tearing convex points of the asphalt layer during crushing, thereby accelerating the crushing efficiency. Then the asphalt particles crushed by the shredder 7 are discharged downward through the discharge port 34 and the discharge port 13 to enter the second conveyor belt and are transported to the left for discharge. Since the diameter of the discharge port 13 is greater than the horizontal length of the box body 21, the discharge port 34 can discharge downward smoothly when dynamically moving to the right for discharge, without any jamming problem.

[0045] When the left planer 44 of the planer board body 42 moves to the right to plan the layer, the old asphalt blocks planed off in the material cavity 22 will move to the top surface of the planer board body 42 in sequence. In this way, after the material box bottom plate 32 moves to the right, a layer of bottom plate can be reinserted into the bottom surface of the box body 21 to support the old asphalt blocks in the material cavity 22, thereby preventing material leakage from the bottom surface of the box body 21.

[0046] When the planer 44 moves to the right to the anti-jamming group 5, it will continue to push to the right to retract the retracting slider 524 to the right, so that the planer 44 can completely and horizontally penetrate the entire cross-section of the material cavity 22, and the old asphalt block in the material cavity 22 can be completely planed. The planer 44 will not be hard against the right wall of the material cavity 22, and the asphalt planing layer at the right end of the material cavity 22 will be squeezed into the left oblique material discharge channel by the triangular protrusion 511. Figure 7 , complete one layer of planing.

[0047] In addition, when the planer board assembly 4 is horizontally moved to the left and reset, the retracting slider 524 will be pushed to the left by the springs 523 to reset, so that the asphalt residue accumulated at the left end of the top surface of the triangular protrusion 511 due to the rightward retraction of the retracting slider 524 will be discharged to the left. During the process of the planer board body 42 being moved to the left and reset, the old asphalt blocks supported by the top surface will fall back onto the material box bottom plate 32 which is synchronously moved to the left and reset.
