Description

[0038] The processing box 1 is provided with a pressing mechanism, which includes a wedge-shaped plate 17 fixedly connected to the inner wall of the processing box 1. The upper end of the rectangular rod 14 is rotatably connected to a wedge-shaped column 16 through a rotating shaft. The wedge-shaped column 16 is in contact with the side wall of the wedge-shaped plate 17 during movement (such as Figure 3 as shown).

[0039] During the movement of the first L-shaped plate 11, the rectangular rod 14 drives the wedge-shaped column 16 to move via the rotating shaft. At this time, the wedge-shaped column 16 will move closer to or farther away from the wedge plate 17 during the movement, that is, the wedge-shaped column 16 is subjected to intermittent pressure from the wedge plate 17. At this time, the kneading plate 8 will move up and down under the pressure exerted on the wedge-shaped column 16 and the elastic force of multiple first springs 10, so that the broken old asphalt concrete can enter between the kneading plate 8 and the first inclined plate 5 for kneading treatment, and it is convenient for the kneaded old asphalt concrete to flow out through the first inclined plate 5.

[0040] One end on the same side of the two first rods 2 passes through the inner wall of the processing box 1 and is fixedly connected to a second gear 21, the two second gears 21 are meshed with each other, and a first motor 23 is fixedly connected to the side wall of the second L-shaped plate 22, and the movable end of the first motor 23 is fixedly connected to one end of one of the first rods 2.

[0041] A first bevel gear 28 is fixedly connected to a side wall of one of the first rods 2 , and a second bevel gear 29 is fixedly connected to an end of the reciprocating screw 24 away from the slider 25 . The first bevel gear 28 and the second bevel gear 29 are meshed with each other.

[0042] A separation cylinder 30 is rotatably connected to the bottom of the treatment box 1, and a plurality of filter holes 31 (such as Figure 6As shown, a third L-shaped plate 32 is fixedly connected to the bottom of the processing box 1, and a hollow rod 33 is rotatably connected to the side wall of the third L-shaped plate 32. A spiral conveying blade 34 is fixedly connected to the side wall of the hollow rod 33. The side wall of the spiral conveying blade 34 is in contact with the inner wall of the separation cylinder 30, and the side wall of the hollow rod 33 is fixedly connected to the inner wall of the separation cylinder 30 through a plurality of connecting rods (as shown in FIG. Figure 6 As shown in FIG. 1 , impurity removal openings 43 are provided on both sides of the lower inner wall of the processing box 1 .

[0043] The inner wall of the treatment box 1 below the first inclined plate 5 is fixedly connected to a V-shaped plate 41, and a discharge port 42 is formed at the upper end of the V-shaped plate 41, and the discharge port 42 is directly opposite to the opening of the separation cylinder 30 (such as Figure 2 as shown).

[0044] A second motor 36 is fixedly connected to the upper end of the third L-shaped plate 32, a first wheel 37 is fixedly connected to the side wall of the movable shaft of the second motor 36, a second wheel 38 is fixedly connected to the side wall of the hollow rod 33, and the first wheel 37 and the second wheel 38 are connected by a synchronous belt.

[0045] The kneaded old asphalt concrete enters the separation drum 30 through the discharge port 42, and then drives the second motor 36 to rotate at high speed, and drives the hollow rod 33 to rotate at high speed through the first wheel 37, the synchronous belt and the second wheel 38, and drives the hollow rod 33, the spiral conveying blade 34 and the separation drum 30 to rotate at high speed. At this time, under the action of centrifugal force, the old asphalt concrete located on the spiral conveying blade 34 will flow out through multiple filter holes 31 after kneading, while the mineral material will be spirally transported downward by the spiral conveying blade 34 and discharged, thereby realizing the rapid separation of the mineral material and the old asphalt in the kneaded old asphalt concrete, and making the old asphalt concrete flow downward in a spiral shape, thereby increasing the flow time of the old asphalt concrete in the separation drum 30 and improving the separation effect.

[0046] The lower end of the third L-shaped plate 32 is fixedly connected to a rotary joint 39 through a bracket, the lower end of the hollow rod 33 is fixedly connected to the upper end of the rotary joint 39, and the lower end of the rotary joint 39 is fixedly connected to a high-pressure air inlet pipe 40. The side wall of the hollow rod 33 located in the separation cylinder 30 is provided with a plurality of jet holes 35. During the rotation of the hollow rod 33, the external high-pressure gas will be ejected from the plurality of jet holes 35 at high speed through the high-pressure air inlet pipe 40, the rotary joint 39 and the hollow rod 33, so as to blow out the impurities remaining in the filter hole 31 and avoid clogging of the filter hole 31 during the separation process.

[0047] After the old asphalt concrete is crushed, the first motor 23 is first driven to rotate. At this time, the first motor 23 drives the two crushing rollers 3 to rotate in the opposite direction through the two second gears 21 and the two first rods 2. Then, the old asphalt concrete is added to the processing box 1 through the feeding pipe 4. Then, the two rotating crushing rollers 3 can crush the old asphalt concrete into large particles, and the crushed old asphalt concrete falls on the first inclined plate 5.

[0048] One of the first rods 2 rotates through the first bevel gear 28 and the second bevel gear 29 to drive the reciprocating screw 24 to rotate, and at this time the slider 25 moves toward the side wall of the processing box 1 or away from the side wall of the processing box 1. At this time, the slider 25 drives the top plate 26 to move synchronously, so that the second inclined plate 6 moves back and forth on the side wall of the processing box 1 under the squeezing of the top plate 26 and the action of multiple second springs 19, so that the first L-shaped plate 11 moves with the second inclined plate 6. At this time, the first gear 13 rotates continuously under the action of the tooth plate 18, driving the rectangular rod 14 to rotate, and then the rectangular rod 14 drives the kneading plate 8 to rotate through the second rod 15, so that during the movement of the second inclined plate 6 above the first inclined plate 5, the kneading plate 8 can move and rotate, kneading the broken old asphalt concrete, which not only reduces the stress strength of the old asphalt concrete, so that the mineral material in the old asphalt concrete remains intact and not easy to be crushed, but also can be removed by kneading the old asphalt adhering to the mineral material;

[0049] In addition, during the movement of the first L-shaped plate 11, the rectangular rod 14 drives the wedge-shaped column 16 to move via the rotating shaft. At this time, the wedge-shaped column 16 will move closer to or farther from the wedge-shaped plate 17 during the movement, that is, the wedge-shaped column 16 is subjected to intermittent pressure from the wedge-shaped plate 17. At this time, the kneading plate 8 will move up and down under the pressure exerted on the wedge-shaped column 16 and the elastic force of the plurality of first springs 10, so that the broken old asphalt concrete can enter between the kneading plate 8 and the first inclined plate 5 for kneading treatment, and facilitate the kneaded old asphalt concrete to flow out through the first inclined plate 5;

[0050] Subsequently, the kneaded old asphalt concrete enters the separation cylinder 30 through the V-shaped plate 41 and the discharge port 42, and then drives the second motor 36 to rotate at high speed, and drives the hollow rod 33 to rotate at high speed through the first wheel 37, the synchronous belt and the second wheel 38, and drives the hollow rod 33, the spiral conveying blade 34 and the separation cylinder 30 to rotate at high speed. At this time, under the action of centrifugal force, the old asphalt concrete located on the spiral conveying blade 34 will flow out through multiple filter holes 31 after kneading, and the mineral material will be spirally transported downward and discharged through the spiral conveying blade 34, so as to realize the rapid separation of the mineral material and the old asphalt in the kneaded old asphalt concrete, and make the old asphalt concrete flow downward in a spiral shape, which increases the flow time of the old asphalt concrete in the separation cylinder 30 and improves the separation effect;

[0051] And during the rotation of the hollow rod 33, the external high-pressure gas can be ejected at high speed from the multiple jet holes 35 through the high-pressure air inlet pipe 40, the rotary joint 39 and the hollow rod 33, which can blow out the impurities remaining in the filter hole 31 to avoid clogging of the filter hole 31 during the separation process.
