Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of recycling, in particular to a pouring forming mold based on broken recycling of asphalt concrete waste. BACKGROUND

[0002] Asphalt concrete is a composite material formed by mixing and compacting asphalt and mineral aggregate in proportion, mainly used for road paving. A large amount of asphalt concrete waste is generated every year due to road maintenance. The waste is usually crushed and sieved for producing various brick products. When the waste is used to make bricks, the waste particles need to be heated to melt the old asphalt and wrap the aggregate, forming a continuous cohesive phase. Then the heated waste particles are placed in the forming cavity of the mold frame, and the waste particles are compressed by the pressing block to expel the internal bubbles, improve the packing density between the aggregates, and avoid the formation of honeycomb defects in the brick body, thereby improving the strength of the brick. After the asphalt in the waste particles is naturally solidified, the brick is pushed out of the forming cavity to complete the brick making process.

[0003] However, there are some problems in the process of making bricks from asphalt concrete waste. During the pressing process, the melted asphalt seeps into the gap between the inner wall of the mold frame and the pressing block, and solidifies on the pressing block. When the mold is removed, the pressing block moves up and pulls the edge of the brick body through the adhesive asphalt, causing the edge of the brick to peel off and be damaged, affecting the integrity and yield of the product. At the same time, the natural solidification process is slow, which not only prolongs the production cycle and restricts the efficiency, but also aggravates the adhesion of the asphalt to the mold due to the long-term sticky state of the asphalt.

[0004] Therefore, the melted asphalt seeps into the gap between the mold frame and the pressing block during the pressing process, forming a sticky structure that causes damage during demolding, and the slow natural solidification affects production efficiency, which is a technical problem that needs to be solved by those skilled in the art.

[0039] After the fixed brick is pressed, the lifting hydraulic cylinder 220 pushes the formed brick up through the lifting plate 22, and the main hydraulic cylinder 16 pulls the moving seat 14 and the pressing block 15 up, until the lower end of the pressing block 15 is at the same horizontal plane as the upper end of the supporting plate 21, then the cutter 20 initially in contact with the left and right ends of the pressing block 15 moves down to cut the asphalt at the left and right ends of the pressing block 15, then the front and rear cutters 20 are in contact with the front and rear ends of the pressing block 15, and the left and right cutters 20 are away from the pressing block 15, then the front and rear cutters 20 in contact with the pressing block 15 are pushed down to cut the asphalt at the front and rear ends of the pressing block 15, so that there is no asphalt bridge between the pressing block 15 and the brick body, eliminating the pulling damage, and the timing operation avoids the interference problem of synchronous cutting, then the left and right cutters 20 are reset in contact with the pressing block 15, and the front and rear cutters 20 are away from the pressing block 15, then the four cutters 20 are reset to move up, and the external air nozzle blows the cut asphalt away from the supporting plate 21 for centralized collection and reuse.

[0040] The lifting hydraulic cylinder 220 continues to push the brick up through the lifting plate 22, and the pressing block 15 is synchronously moved up through the main hydraulic cylinder 16, until the upper end surface of the lifting plate 22 is at the same horizontal plane as the upper end surface of the supporting plate 21, then the external pushing device pushes the brick away from the supporting plate 21 for centralized collection and processing, then the above operation is repeated to continue the asphalt concrete waste brick making process.

[0041] As shown in Figure 1 and Figure 5 , a first lifting plate 26 is arranged between the front and rear two connecting plates 240, the opposite surfaces of the front and rear two connecting plates 240 are each fixedly installed with a pair of first guide columns 27, and the front and rear ends of the first lifting plate 26 are each provided with a circular hole in sliding connection with the first guide column 27.

[0042] As shown in Figure 1 and Figure 5As shown, two left and right relative sliding plates 25 are provided with a second lifting plate 28 below a first lifting plate 26, and the opposite sides of two left and right relative connecting plates 240 are each provided with a vertical plate fixedly installed at the upper end of the second lifting plate 28, and the opposite sides of the two left and right relative connecting plates 240 are each fixedly installed with a pair of second guide columns 29, and the second guide columns 29 slide through the corresponding vertical plate away from the corresponding connecting plate 240.

[0043] As shown in Figure 1 and Figure 5 As shown, the moving seat 14 is provided with a driving part 3 for driving the first lifting plate 26 and the second lifting plate 28 to move downward in sequence, the driving part 3 includes two push-pull hydraulic cylinders 30 which are left and right symmetrical about the connecting plate 240 and are fixedly installed at the upper end of the moving seat 14, the extension section of the left push-pull hydraulic cylinder 30 is fixedly connected with the second lifting plate 28 through a second connecting plate 32, and the extension section of the right push-pull hydraulic cylinder 30 is fixedly connected with the first lifting plate 26 through a first connecting plate 31.

[0044] As shown in Figure 5 As shown, the upper end of the first lifting plate 26 is fixedly installed with a bidirectional hydraulic cylinder 260, and the two extension sections of the bidirectional hydraulic cylinder 260 are respectively fixedly connected with two front and rear distributed connecting plates 240.

[0045] As shown in Figure 5 and Figure 6 As shown, a linkage is arranged between the sliding plates 25, and the linkage includes a connecting rod 250, and the connecting rod 250 is hinged between two adjacent sliding plates 25.

[0046] As shown in Figures 1 to 7 As shown, in specific work, the jacking hydraulic cylinder 220 pushes the formed brick block to move upward, and the main hydraulic cylinder 16 synchronously drives the fixed plate and the pressing block 15 to move upward until the lower end surface of the pressing block 15 and the upper end surface of the supporting plate 21 are located on the same horizontal plane, at this time, the brick block will not exceed the upper end surface of the mold frame 13 (as shown in Figure 7 the upper state diagram), and then the left push-pull hydraulic cylinder 30 pulls the second lifting plate 28 downward through the second connecting plate 32, the second lifting plate 28 drives the two left and right connecting plates 240 to move downward through the second guide column 29, and the connecting plate 240 drives the two left and right cutters 20 which are in initial state and are attached to the left and right ends of the pressing block 15 to move downward through the corresponding sliding rod 24, and the cutter 20 moves downward and abuts against the upper end of the mold frame 13 (as shown in Figure 7(In the state diagram of the middle part) the asphalt on the left and right sides of the pressure block 15 is cut off. Then the bidirectional hydraulic cylinder 260 pulls the front and rear connecting plates 240 closer to each other. The front and rear connecting plates 240 drive the corresponding fixed plates and sliding plates 25 to move towards the pressure block 15 through the corresponding sliding rods 24. The fixed plates drive the cutting ends of the front and rear cutters 20 to fit against the front and rear end faces of the pressure block 15. As the front and rear sliding plates 25 move closer to each other, the connecting rod 250 pushes the left and right sliding plates 25 away from each other. The left and right sliding plates 25 drive the corresponding cutters 20 away from the pressure block 15 through the corresponding sliding rods 24 and fixed plates. The cutters 20 drive the cut asphalt away from the pressure block 15.

[0047] Then, the right-side push-pull hydraulic cylinder 30 pushes the first lifting plate 26 downward through the first connecting plate 31. The first lifting plate 26 then drives the front and rear connecting plates 240 downward through the first guide column 27. The front and rear connecting plates 240 then drive the front and rear cutters 20 downward through the corresponding sliding rods 24 and fixing plates. The front and rear cutters 20 move downward while maintaining contact with the pressure block 15, so as to cut the asphalt at both ends of the pressure block 15 (e.g., Figure 7 (See the lower part of the diagram). Then, the bidirectional hydraulic cylinder 260 pushes the front and rear connecting plates 240 away from each other. The front and rear connecting plates 240 then drive the corresponding sliding plates 25 and fixed plates to move through the corresponding sliding rods 24. The movement of the front and rear sliding plates 25 pulls the left and right cutters 20 closer to each other through the connecting rod 250 until the cutting ends of the left and right cutters 20 are in contact with the left and right end faces of the pressure block 15. The front and rear fixed plates then drive the front and rear cutters 20 away from the pressure block 15 to push the cut asphalt away from the pressure block 15. Then, the cut asphalt is blown off the support plate 21 by an external air nozzle for centralized collection and reuse. Then, the lifting hydraulic cylinder 220 continues to push the brick upward through the lifting plate 22, and the pressing block 15 moves upward at the same time until the brick is completely separated from the mold frame 13. At this time, the upper end of the lifting plate 22 and the upper end of the support plate 21 are on the same horizontal plane. Then, the main hydraulic cylinder 16 pulls the pressing block 15 away from the brick through the fixing plate. Then, the external pushing device pushes the brick away from the support plate 21 for centralized collection and processing. At the same time, the pushing device continues to push the heated asphalt concrete waste particles into the forming cavity of the mold frame 13 to continue the brick making process after crushing the asphalt concrete waste.
