Description

Technical Field

[0001] This utility model belongs to the field of road construction technology, and in particular relates to an asphalt mixture paver for highway construction. Background Technology

[0002] With rapid economic development, the demand for highway construction is increasing. Highways have extremely high requirements for road surface smoothness, strength, and durability. As a key piece of equipment in road construction, the performance of asphalt pavers directly affects road surface quality. Traditional pavers have gradually revealed some shortcomings when facing large-scale, high-quality highway construction. For example, in some early highways, the insufficient precision of the pavers resulted in poor road surface smoothness, reduced vehicle comfort, and increased maintenance costs.

[0003] However, existing asphalt pavers used in highway construction are not convenient for cleaning the base course. If there is a lot of dust and particles on the base course surface, an isolation layer will form between the asphalt layer and the base course, affecting the bonding effect and thus reducing the overall quality of the road surface. Utility Model Content

[0004] The purpose of this utility model is to provide an asphalt mixture paver for highway construction. By setting up a cleaning mechanism, it solves the problem of inconvenient cleaning of the base road surface. If there is a lot of dust and particles on the base surface, an isolation layer will be formed between the asphalt layer and the base, affecting the bonding effect and thus reducing the overall quality of the road surface.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an asphalt mixture paver for highway construction, including a fixed frame, on which a cleaning mechanism and a dust collection mechanism are provided;

[0007] A paving box is fixedly connected to the left side of the fixed frame. The cleaning mechanism includes a reciprocating screw rotatably connected to the fixed frame. A slider is threadedly connected to the outer wall of the reciprocating screw. A telescopic rod is fixedly connected to the bottom of the slider. A fixed plate is fixedly connected to the bottom of the telescopic rod. Several telescopic plates are provided at the bottom of the fixed plate.

[0008] Furthermore, each of the telescopic plates is provided with a T-shaped groove, and an H-shaped slider is slidably connected in each of the T-shaped grooves. Fixing blocks are fixedly connected to the top of the telescopic plates located on the front and rear sides.

[0009] Furthermore, each of the two fixed blocks is fixedly connected to a sliding rod on the side away from each other, and the fixed frame has two sliding grooves, in which the two sliding rods are slidably connected.

[0010] Furthermore, the front and rear sides of the fixing frame are fixedly connected with fixing rods, and the two fixing rods are fixedly connected with limiting plates, and the two sliding rods are in contact with the limiting plates respectively.

[0011] Furthermore, both of the limiting plates are hinged with hinge rods, and a second fixing plate is fixedly connected to the fixing frame. A rotating shaft is rotatably connected between the two fixing plates, and the rear side of the rotating shaft extends rotatably out of the second fixing plate.

[0012] Furthermore, a cleaning roller is fixedly connected to the outer wall of the rotating shaft, and a motor is fixedly connected to the second fixed plate located at the rear. The output shaft of the first motor is fixedly connected to the rotating shaft through a coupling. A second motor is fixedly connected to the left side of the fixed frame, and the output shaft of the second motor is fixedly connected to the reciprocating lead screw through a coupling.

[0013] Furthermore, the dust collection mechanism includes a dust collection box connected to the top of the fixed frame, a filter plate fixedly connected to the dust collection box, and a fan fixedly connected to the inner wall of the dust collection box.

[0014] Furthermore, the dust collection box is connected to several pipes, and each of the pipes has an air inlet.

[0015] This utility model has the following beneficial effects:

[0016] 1. By setting up a cleaning mechanism, before laying asphalt, start motor one. Motor one will rotate the shaft, and the sweeping roller will also rotate. At this time, small particles and dust on the road surface will be swept into the fixed frame by the sweeping roller. Then start motor two, and the reciprocating screw will be driven by motor two. When the reciprocating screw rotates, the slider will move, and the telescopic rod will move accordingly. When the telescopic rod moves, the fixed plate one will also move, and thus the telescopic plate will move. In turn, the fixed block on the telescopic plate will also move. When the fixed block moves, the sliding rod will also move. When the sliding rod moves, it will move in the sliding groove. At this time, as the tilt angle of the fixed frame increases, the sliding rod will pull the fixed block. When the fixed block is pulled, the telescopic plate will also move. When the telescopic plate is pulled, the corresponding H-shaped slider in the T-shaped sliding groove will also move accordingly. In this way, the telescopic plate will achieve the same tilt angle as the fixed frame. The telescopic effect works as follows: when the slider moves to the far right of the chute, the sliding rod falls, and the telescopic plate contacts the bottom inner wall of the fixed frame. The slider then moves in the opposite direction, thus scraping away dust and particles from the fixed frame. The telescopic plate then carries the dust and particles to the left. As the sliding rod continues to move, it contacts the hinge rod, which is then lifted by the sliding rod. Once the hinge rod is lifted, it can pass through, and then it falls. At the same time, the dust and particles carried by the telescopic plate fall into the collection box. When the slider reaches the left side, it moves to the right again, and the sliding rod contacts the hinge rod again. The sliding rod then moves upward along the hinge rod, thus cleaning particles and dust from the roadbed. This prevents problems such as road surface depressions or bumps caused by uneven base layers after asphalt paving, and helps ensure the smoothness of the asphalt pavement.

[0017] 2. By setting up a dust collection mechanism, the rotation of the sweeping rollers will raise dust on the road surface. At this time, the fan will be started, and the raised dust will be sucked into the air inlet on the pipe. The dust will then reach the dust collection box and fall into the fixed frame. The air will be filtered by the filter plate and discharged out of the dust collection box. This achieves the effect of dust control, which can effectively reduce the content of inhalable particulate matter in the air and reduce the risk of respiratory diseases and other health problems caused by construction dust.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] Please see Figure 1-5As shown, this utility model is an asphalt mixture paver for highway construction, including a fixed frame 1. A cleaning mechanism 2 and a dust collection mechanism 3 are installed on the fixed frame 1. A paving box 101 is fixedly connected to the left side of the fixed frame 1. The cleaning mechanism 2 includes a reciprocating screw 211 rotatably connected to the fixed frame 1. A slider 212 is threaded onto the outer wall of the reciprocating screw 211. A telescopic rod 213 is fixedly connected to the bottom of the slider 212. A fixing plate 214 is fixedly connected to the bottom of the telescopic rod 213. The bottom of 214 is provided with several telescopic plates 215, each of which has a T-shaped groove 216. H-shaped sliders 217 are slidably connected within each T-shaped groove 216. Fixing blocks 218 are fixedly connected to the top of the front and rear telescopic plates 215. Sliding rods 219 are fixedly connected to the sides of the two fixing blocks 218 that are far apart from each other. The fixing frame 1 has two grooves 2110, and the two sliding rods 219 are slidably connected within the grooves 2110. The front side of the fixing frame 1... Both the front and rear sides are fixedly connected to a fixing rod 2111. A limit plate 2112 is fixedly connected to each fixing rod 2111. Two sliding rods 219 are in contact with the limit plates 2112. A hinge rod 2113 is hinged to each limit plate 2112. A second fixing plate 2114 is fixedly connected to the fixing frame 1. A rotating shaft 2115 is rotatably connected between the second fixing plates 2114. The rear side of the rotating shaft 2115 extends rotatably beyond the second fixing plate 2114. A cleaning device is fixedly connected to the outer wall of the rotating shaft 2115. Roller 2116, with motor 2117 fixedly connected to the fixed plate 2114 on the rear side. The output shaft of motor 2117 is fixedly connected to the rotating shaft 2115 through a coupling. Motor 2118 is fixedly connected to the left side of the fixed frame 1. The output shaft of motor 2118 is fixedly connected to the reciprocating screw 211 through a coupling. By setting up the cleaning mechanism 2, problems such as road surface depressions or bumps caused by uneven base layer after asphalt paving are avoided, which helps to ensure the smoothness of the asphalt pavement.

[0029] The dust collection mechanism 3 includes a dust collection box 311 connected to the top of the fixed frame 1. A filter plate 312 is fixedly connected to the dust collection box 311. A fan 313 is fixedly connected to the inner wall of the dust collection box 311. Several pipes 314 are connected to the dust collection box 311. Each of the pipes 314 has an air inlet 315. By setting up the dust collection mechanism 3, the content of inhalable particulate matter in the air can be effectively reduced, thereby reducing the risk of respiratory diseases and other health problems caused by construction dust.

[0030] A specific application of this embodiment is as follows: In use, first place the device in the appropriate position, then start motor 2117. Motor 2117 will then rotate shaft 2115. When shaft 2115 rotates, sweeping roller 2116 will also rotate. Small particles and dust on the road surface will be swept into the fixed frame 1 by sweeping roller 2116. Then, start motor 2118. Simultaneously, reciprocating screw 211 will be driven by motor 2118. When reciprocating screw 211 rotates, slider 212 will move, causing telescopic rod 213 to move as well. When telescopic rod 213 moves, fixed plate 214 will also move simultaneously, thus telescopic plate 215 will also move. The movement of the telescopic plate 215 causes the fixed block 218 on it to move as well. When the fixed block 218 moves, the sliding rod 219 also moves, moving within the slide groove 2110. As the tilt angle of the fixing frame 1 increases, the sliding rod 219 pulls the fixed block 218. This pulling of the fixed block 218 causes the telescopic plate 215 to move as well. When the telescopic plate 215 is pulled, the corresponding H-shaped slider 217 in the T-shaped slide groove 216 also moves. Thus, the telescopic plate 215 achieves the effect of extending and retracting according to the tilt angle of the fixing frame 1. When the slider 212 moves to the rightmost side of the slide groove 2110, the sliding rod 21... When slide bar 215 (215) falls, it will contact the bottom inner wall of the fixed frame 1. At this point, slide bar 212 will move in the opposite direction, thus scraping away dust and particles inside the fixed frame 1. The slide bar 215 will then move to the left, carrying the dust and particles. As slide bar 219 continues to move, it will contact hinge rod 2113, lifting it. Once hinge rod 2113 is lifted, slide bar 219 can pass through, and after it passes, hinge rod 2113 will fall. Simultaneously, the dust and particles carried by the slide bar 215 will fall into the collection box. When slide bar 212 reaches the left side... It will then move to the right again, at which point the slide bar 219 will contact the hinge bar 2113 again, and the slide bar 219 will move upward along the hinge bar 2113, thereby achieving the effect of cleaning particles and dust on the road surface. Because the rotation of the sweeping roller 2116 will raise the dust on the road surface, the fan 313 will be started. After the fan 313 is started, the raised dust will be sucked into the air inlet 315 on the pipe 314 by the fan 313, and then the dust will reach the dust collection box 311. At this time, the sucked-in dust will fall into the fixed frame 1, and the air will be filtered by the filter plate 312 and discharged out of the dust collection box 311 again, thereby achieving the effect of dust control.
