Description

Technical Field

[0001] The invention relates to aggregate and emulsified asphalt integrated spreading equipment, belonging to the field of emulsified asphalt spreading. Background Art

[0002] As my country's highway network gradually improves, the concept of highway construction has gradually transformed from "construction-oriented" to the current "equal emphasis on construction and maintenance" and then to "maintenance-oriented" in the future. Preventive pavement maintenance can prevent the further spread of diseases in the early stages, which not only extends the service life of the pavement and saves life cycle costs, but also ensures the service function of the pavement. In recent years, it has been highly valued by road practitioners. In the process of highway maintenance, it is necessary to use spreading equipment to spray emulsified asphalt to achieve the effect of highway maintenance or repair.

[0003] However, the existing emulsified asphalt spreading equipment can spray emulsified asphalt during actual operation, but it does not have the automatic proportioning and automatic feeding functions of emulsified asphalt. Therefore, it needs to stop working after spraying the emulsified asphalt. Then the staff needs to use other equipment to proportion the emulsified asphalt and perform subsequent loading work on the spreading equipment, which is labor-intensive and has low work efficiency. In addition, the existing emulsified asphalt spreading equipment cannot conveniently adjust the spraying range and spraying amount of emulsified asphalt according to actual conditions during actual operation, and has poor practicality and applicability. Therefore, we have made improvements to this and proposed an integrated aggregate and emulsified asphalt spreading equipment. Summary of the Invention

[0016] Beneficial effects

[0017] The present invention provides an integrated aggregate and emulsified asphalt spreading device, which has the following beneficial effects:

[0018] 1. By rotating the one-way threaded rod, the threaded baffle can be driven to move upward or downward, thereby conveniently adjusting the internal storage space of the transfer trough. By adjusting the internal storage space of the four transfer troughs separately, and utilizing the reciprocating screw rod to drive the threaded sliding cylinder to perform stable up and down reciprocating motion, the intermittent alignment of each transfer trough with the corresponding discharge trough can achieve accurate proportioning of asphalt, emulsifier, water and auxiliary materials and automatic intermittent discharge, ensuring the convenience and efficiency of the subsequent preparation of emulsified asphalt, and automatically replenishing and discharging during the continuous operation of the device, effectively improving the working efficiency of the spreading equipment.

[0019] 2. Through the up and down reciprocating motion of the sliding cylinder, combined with the guide rod and the guide groove, the first connecting cylinder can be driven to rotate back and forth during the up and down reciprocating motion, and then the various driven shafts can be driven to perform synchronous up and down reciprocating motion and reciprocating revolution. At the same time, under the meshing drive action of the first bevel gear and the second bevel gear, the various driven shafts that reciprocate can be driven to rotate back and forth. Combined with the various spiral blades, the intermittently fed asphalt, emulsifier, water and auxiliary materials can be mixed and stirred in an all-round and efficient manner, realizing the efficient preparation of emulsified asphalt and ensuring the stability and convenience of the subsequent spreading of emulsified asphalt. In the working process of the first connecting cylinder, the push rod on the connecting plate can drive the sliding plate to reciprocate left and right while rotating. Combined with the various mixing plates, the mixing preparation efficiency of the emulsified asphalt can be further improved, thereby improving the efficiency of the subsequent spreading work.

[0020] 3. A telescopic frame is formed by setting the first adjusting rod, the second adjusting rod, the third adjusting rod and the fourth adjusting rod. The bidirectional threaded rod can drive the mounting plates on both sides to move toward the middle or both sides at the same time, thereby pulling the telescopic frame to extend or contract. By driving the telescopic frame to extend or contract, the first connecting block and the second connecting block at each connection node can be automatically and stably adjusted to equal spacing. No matter how the adjustment is made, the spacing between adjacent first connecting blocks and second connecting blocks is always the same; by increasing or decreasing the spacing between adjacent first connecting blocks and second connecting blocks, the spreading range of the emulsified asphalt can be conveniently adjusted according to actual conditions, thereby increasing the practicality and applicability of the spreading device.

[0021] 4. The transfer frame can evenly deliver the emulsified asphalt to the nozzles at the ends of each rubber hose. By adjusting the number of asphalt delivery pumps opened, the delivery volume of the emulsified asphalt can be adjusted, and the spraying volume of the emulsified asphalt can be conveniently adjusted according to actual needs.

By driving the telescopic frame to extend or contract, the first connecting block 608 and the second connecting block 612 at each connection node are automatically and stably adjusted to equal spacing. No matter how they are adjusted, the spacing between adjacent first connecting blocks 608 and second connecting blocks 612 is always the same; by increasing or decreasing the spacing between adjacent first connecting blocks 608 and second connecting blocks 612, the spreading range of the emulsified asphalt can be conveniently adjusted according to actual conditions.

[0052] Example 3:

[0053] The solutions in Example 1 and Example 2 are further introduced below in conjunction with specific working methods, as described below:

[0054] Specifically, when the present integrated spreading equipment for aggregate and emulsified asphalt is in use: first, the staff can deliver asphalt, emulsifier, water and auxiliary materials into the four storage boxes 401 respectively through the feed port 402, and then the staff can rotate the one-way threaded rod 412 on the sliding cylinder 411. Under the rotation of the one-way threaded rod 412, the threaded baffle 413 can be driven to move upward or downward. The movement of the baffle 413 can partially block the internal storage space of the transfer tank 414, thereby realizing the adjustment of the internal storage space of the transfer tank 414. Through the same operation, the internal storage space of the four transfer tanks 414 can be conveniently adjusted respectively, so as to realize the accurate proportioning of asphalt, emulsifier, water and auxiliary materials;

[0055] Then the staff can drive the first servo motor 405 on the cover plate 404. Under the driving action of the first servo motor 405, the first circular gear 406 and the reciprocating screw 410 can be driven to rotate simultaneously through the output shaft. Under the rotation action of the first circular gear 406, the corresponding rotating shaft 408 can be driven to rotate through the meshing second circular gears 407. At this time, the rotating shaft 408 combined with the stirring blades 409 can continuously stir the asphalt, emulsifier, water or auxiliary materials in the storage box 401 to ensure the stability of the subsequent feeding work; and during the rotation of the reciprocating screw 410, the sliding cylinder 411 connected by the thread can be driven to stably move inside the sealing cylinder 415. The sliding cylinder 411 reciprocates up and down, and when it moves upward, it can drive each transfer trough 414 to align with the unloading trough 403 on the corresponding storage box 401. At this time, the asphalt, emulsifier, water or auxiliary materials in the storage box 401 can be automatically transported to the corresponding transfer trough 414, and then the sliding cylinder 411 moves downward. At this time, the sliding cylinder 411 can drive each transfer trough 414 to move downward to the bottom of the sealing cylinder 415. At this time, there is no obstruction from the sealing cylinder 415, and the asphalt, emulsifier, water or auxiliary materials in each transfer trough 414 can be automatically transported to the device housing 1. This reciprocating process can conveniently and stably complete the accurate proportioning of asphalt, emulsifier, water and auxiliary materials and the automatic intermittent unloading work;

[0056] At the same time, during the up and down reciprocating motion of the sliding cylinder 411, the first connecting cylinder 501 and the second connecting cylinder 506 at the bottom can be driven to move synchronously. Under the action of the movement of the first connecting cylinder 501, the guide rod 503 on the inner wall can be driven to slide within the guide groove 505 on the fixed rod 504. Under the guidance of the guide groove 505, the first connecting cylinder 501 in the up and down reciprocating motion can be driven to automatically reciprocate through the guide rod 503. At this time, during the reciprocating rotation of the first connecting cylinder 501, each driven shaft 508 can be driven to reciprocate synchronously. During the reciprocating revolution of each driven shaft 508 Since the second connecting cylinder 506 does not rotate, the second bevel gear 509 on each driven shaft 508 can be meshed and driven at the first bevel gear 507 on the second connecting cylinder 506. At this time, each driven shaft 508 not only performs synchronous up and down reciprocating motion and reciprocating revolution, but also can automatically and stably reciprocate and rotate. Combined with the spiral blades 510 on the driven shaft 508, the intermittently fed asphalt, emulsifier, water and auxiliary materials can be mixed and stirred in an all-round and efficient manner. Combined with the heating effect of the electric heating tubes 3 inside the insulation frame 2, the efficient preparation of emulsified asphalt is achieved, ensuring the stability and convenience of the subsequent spreading of the emulsified asphalt.

[0057] Furthermore, during the reciprocating rotation of the first connecting cylinder 501, the push rods 512 on the connecting plates 511 can also drive the sliding plates 513 to rotate synchronously. At the same time, the up and down reciprocating motion of the first connecting cylinder 501 can be used to push the sliding plates 513 to slide back and forth left and right through the push rods 512 on the connecting plates 511. Combined with the mixing plates 514 on the sliding plates 513, the intermittently fed asphalt, emulsifier, water and auxiliary materials can be further mixed and stirred in an all-round and efficient manner, thereby further improving the mixing and preparation efficiency of the emulsified asphalt, thereby improving the efficiency of subsequent spreading work.

[0058] After the emulsified asphalt is mixed and prepared, the staff can again transport asphalt, emulsifier, water and auxiliary materials into the four storage boxes 401 for standby use. Then the staff can push the entire device to the road surface that needs to be repaired or maintained. At this time, the staff can drive the second servo motor 602 on the fixed plate 601. Under the driving action of the second servo motor 602, the bidirectional threaded rod 603 can be driven to rotate stably, and then the mounting plates 604 threadedly connected on both sides can be driven to move toward the middle or both sides at the same time. Under the movement action of the mounting plates 604 on both sides, the second connecting blocks 612 fixedly connected can be driven to move synchronously. Under the movement action of the second connecting blocks 612 on both sides, the telescopic frames composed of the first adjusting rod 605, the second adjusting rod 606, the third adjusting rod 609 and the fourth adjusting rod 610 can be driven to extend or retract. No matter how the telescopic frames are extended or retracted, each group of first adjusting rods 605, 606, 609 and the fourth adjusting rod 610 can be driven to extend or retract. The distance between the first connecting shaft 607 at the connection between the rod 605 and the corresponding second adjustment rod 606 is always equal, and the distance between adjacent first connecting blocks 608 and the distance between the first connecting block 608 and the adjacent second connecting block 612 is the same. Therefore, the distance between each nozzle 614 is always the same, and the distance between each nozzle 614 can be adjusted to increase or decrease according to actual conditions, thereby conveniently adjusting the spreading range of the emulsified asphalt according to actual conditions. At the same time, the staff can adjust the number of asphalt delivery pumps 7 opened and the corresponding fixed pipes 8 to adjust the delivery amount of emulsified asphalt delivered to the inside of the transfer frame 9. The transfer frame 9 can be used to evenly deliver the emulsified asphalt to the nozzles 614 at the ends of each rubber hose 613. By adjusting the delivery amount of the emulsified asphalt, the spraying amount of the emulsified asphalt can be conveniently adjusted according to actual needs.

[0059] Then, under the action of the universal wheel 10, the staff can use the fixed handle 11 to pull the device housing 1 to move the position to realize the spreading of emulsified asphalt, and the staff can also remove the bolts on the universal wheel 10 to complete the disassembly of the universal wheel 10, and then use the bolts to install the entire device on the tractor, and use the tractor's travel to drive the device to spread emulsified asphalt on the road surface. After the spreading work on a section of the road is completed, when the device moves to the next section of the road surface, it can drive the first servo motor 405 again, and use the automatic mixing aggregate component 4 and the high-efficiency emulsification component 5 to carry out the proportioning and efficient mixing preparation of asphalt, emulsifier, water and auxiliary materials again, and use spare materials to supplement the emulsified asphalt, reducing the time and labor intensity of loading, thereby improving work efficiency.
