Description

Technical Field

[0001] The invention belongs to the technical field of asphalt paving, in particular to an automatic asphalt mixture paving device. Background Art

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a high-viscosity organic liquid that is in liquid form with a black surface and is soluble in carbon disulfide. Asphalt is an organic cementitious material that is waterproof, moisture-proof and corrosion-resistant. Asphalt can be mainly divided into three types: coal tar asphalt, petroleum asphalt and natural asphalt. Coal tar asphalt is a by-product of coking; petroleum asphalt is the residue after crude oil distillation; natural asphalt is stored underground, some of which form mineral layers or accumulate on the surface of the earth's crust. Asphalt is mainly used in industries such as coatings, plastics, rubber, and road paving.

[0003] A patent with publication number CN117488627A discloses an asphalt paving device for environmentally friendly highway construction, including a movable base, a stirring mechanism connected to the top of the base, an opening on one side of the base, a first pressure roller sliding in the space inside the opening, and a hydraulic cylinder connected to the bottom of the stirring mechanism. The present invention is provided with a push plate, which can push away the asphalt pile on the ground, so that the asphalt can be better laid on the ground. In addition, the degree of automation is high when spreading the asphalt, which saves labor costs and reduces the labor costs used in laying asphalt. It has good social benefits and reduces the workload of workers. In addition, during use, the rotation of the first screw can drive the scraper to clean the push plate, and can drive the shielding plate to unfold, which facilitates the push plate to push excess materials into the side box, thereby improving the practicality of the paving device.

[0004] In the current existing technology, the existing asphalt is laid on the ground by an asphalt paver, and after the asphalt is laid, the asphalt is rolled by a roller to make the asphalt more dense. However, before the asphalt is processed, the asphalt needs to be processed separately and the processed asphalt is transported to the side of the asphalt paver, transported to the interior of the asphalt paver, and laid out by the asphalt paver. However, after the asphalt is heated, its surface will have greater adhesion, so that the asphalt will clump inside the asphalt paver, which will cause the clumped asphalt to easily cause blockage at the delivery port.

[0005] To this end, the present invention provides an automatic asphalt mixture paving device. Summary of the Invention

[0011] Preferably, two groups of air guide tubes are fixedly connected to the output end of the air pump, and a heating plate is fixedly connected to one end of the two groups of air guide tubes.

[0012] Preferably, a support rod is fixedly connected to the bottom surface of the material-diverting sleeve, a sleeve is movably sleeved on the outer surface of the support rod, and a counterweight plate is fixedly connected to one side surface of the sleeve.

[0014] Preferably, a clamping ring is fixedly connected to the outer surface of the differentiation cylinder, and a differentiation claw is fixedly connected to the outer surface of the clamping ring.

[0015] Preferably, support arm plates are fixedly connected to both side surfaces of the asphalt transport vehicle, the outer surface of the heating plate is arranged on the inner wall surface of the support arm plate, and the inner wall surface of the support arm plate is provided with motor 2 in the middle position.

[0016] Preferably, a second support frame is provided on the outer surface of the second motor, a rolling roller is fixedly connected to one end of the second support frame, and a cooling water tank is provided on the inner wall surface of the rolling roller.

[0017] The beneficial effects of the present invention are as follows: 1. The automatic asphalt mixture paving device of the present invention, after the asphalt is guided into the interior of the asphalt delivery vehicle, cooperates with the motor on the outer surface of the first support frame to rotate the rotating disk, and causes the rotating disk to rotate at a uniform speed. Whenever the first pushing tooth on the outer surface of the rotating disk contacts the second pushing tooth, it pushes the pull-out rod on the outer surface of the second pushing tooth, causing the pull-out rod to slide on the inner wall surface of the support housing and squeeze the elastic wire. When the first pushing tooth passes over the second pushing tooth, the squeezed elastic wire pushes the pull-out rod in the opposite direction. Under the continuous rotation of the rotating disk, the pushing process is repeated. 2. In the automated asphalt mixture paving device described in the present invention, when the pull-out rod slides back and forth on the inner wall surfaces of the support sleeve and the limiting sleeve, the swing arm plate swings left and right under the back-and-forth push of the pull-out rod, and the swinging swing arm plate drives the retracting rod to retract and retract.

In the automated asphalt mixture paving device described in the present invention, when the lever is agitated inside the asphalt delivery vehicle, hot air emitted from the asphalt accumulates inside the vehicle. At this time, the exhaust pump is used to evacuate the interior of the exhaust heating box, thereby absorbing and directing the hot air from inside the vehicle. The hot air flowing in the air guide pipe is then discharged onto the asphalt surface through the heating plate, thereby maintaining the asphalt surface in a hot state. 4. The present invention describes an automatic asphalt mixture paving device. When the asphalt is discharged through the material dispensing sleeve, the asphalt material will be laid on the two side surfaces of the corrugated plate. When the asphalt delivery vehicle moves, the corrugated plate will slide inside the asphalt material. At this time, the corrugated plate will swing left and right inside the asphalt material when it slides, and the swinging corrugated plate will shake off the accumulated asphalt so that the asphalt can be laid on the road surface. While the corrugated plate is swinging, the speaker limit plate is used to limit the swing angle of the corrugated plate, and the plate will swing left and right repeatedly under the guidance of the asphalt material.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figures 1 to 5As shown, an automatic asphalt mixture paving device according to an embodiment of the present invention includes an asphalt delivery vehicle 11, a support sleeve 118 is fixedly connected to the outer surface of the asphalt delivery vehicle 11, and limiting sleeves 117 are fixedly connected to the inner wall surfaces of both sides of the asphalt delivery vehicle 11, a pulling rod 119 is movably sleeved on the inner wall surfaces of the support sleeve 118 and the limiting sleeve 117, an elastic wire 1111 arranged on one end of the pulling rod 119 is fixedly connected to the inner wall surface of the support sleeve 118, a pushing tooth 2 1110 is fixedly connected to the top surface of the pulling rod 119, a swing arm plate 1112 is swingably connected to the outer surface of the pulling rod 119, a retraction rod 1113 is movably sleeved on one end of the swing arm plate 1112, the outer surface of one end of the retraction rod 1113 is movably sleeved on the inner wall surface of the asphalt delivery vehicle 11, and a toggle rod 1114 is fixedly connected to the outer surface of the retraction rod 1113; A support frame a1 is fixedly connected to one side surface of the asphalt transport vehicle 11, a rotating disk a2 is provided on one end of the support frame a1, and a push gear a3 movably sleeved on the outer surface of the push gear 2 1110 is fixedly connected to the outer surface of the rotating disk a2.

[0023] After the asphalt flows into the interior of the asphalt transport vehicle 11, the motor on the outer surface of the support frame a1 rotates the rotating disk a2 and makes the rotating disk a2 rotate at a uniform speed. Whenever the pushing tooth a3 on the outer surface of the rotating disk a2 fits into contact with the pushing tooth 2 1110, it pushes the pulling rod 119 on the outer surface of the pushing tooth 2 1110, and makes the pulling rod 119 slide on the inner wall surface of the support shell 118 and squeeze the elastic wire 1111. When the pushing tooth a3 passes over the pushing tooth 2 1110, the squeezed elastic wire 1111 pushes the pulling rod 119 in the opposite direction. Under the continuous rotation of the rotating disk a2, the pushing process effect is achieved repeatedly. When the pulling rod 119 slides back and forth on the inner wall of the supporting sleeve 118 and the limiting sleeve 117, the swing arm plate 1112 will swing left and right along the back and forth push of the pulling rod 119, and the swinging swing arm plate 1112 will drive the retraction rod 1113 to retract and retract, and the toggle rod 1114 repeatedly squeezes the inside of the asphalt under the left and right swing of the retraction rod 1113, so that some adhered and clumped asphalt can be loosened, and the asphalt that is stirred and loosened will be slowly discharged through the toggle sleeve 114.

[0024] like Figures 1-4 and Figures 6 and 7As shown, an inclined groove is provided on the inner wall surface of the bottom of the material dispensing sleeve 114, a motor 115 is fixedly installed on the inner wall surface of the asphalt delivery vehicle 11, a differentiation cylinder 116 is fixedly connected to the output of the motor 115, and an air pump 111 is fixedly installed on the top surface of the asphalt delivery vehicle 11.

[0025] When the asphalt is discharged through the material discharging sleeve 114, the differentiation cylinder 116 is rotated in conjunction with the motor 115. The differentiation claws 1162 on the surface of the rotating differentiation cylinder 116 will contact the asphalt blocks and squeeze and crush the asphalt clumps, so that the asphalt can be gradually discharged in the smallest state.

[0026] like Figures 1 to 2 and Figure 8 As shown, an exhaust heating box 1115 is fixedly installed on the inner wall of the top of the asphalt transport vehicle 11, a material dispensing sleeve 114 is fixedly connected to the bottom surface of the asphalt transport vehicle 11, two groups of air guide pipes 112 are fixedly connected to the output end of the exhaust pump 111, and a heating plate 113 is fixedly connected to one end of the two groups of air guide pipes 112. A clamping ring 1161 is fixedly connected to the outer surface of the differentiation cylinder 116, and a differentiation claw 1162 is fixedly connected to the outer surface of the clamping ring 1161. The support arm plate 12 is fixedly connected to the two side surfaces of the asphalt transport vehicle 11, and the outer surface of the heating plate 113 is arranged on the inner wall of the support arm plate 12. A motor 2 121 is arranged on the inner wall of the support arm plate 12 and in the middle position. A support frame 2 122 is arranged on the outer surface of the motor 2 121, and a rolling roller 123 is fixedly connected to one end of the support frame 2 122. A cooling water tank 124 is arranged on the inner wall of the rolling roller 123.

[0027] When the lever 1114 is turned to stir the asphalt inside the asphalt delivery vehicle 11, the hot air emitted from the asphalt inside will accumulate inside the asphalt delivery vehicle 11. At this time, the air extraction pump 111 is used to extract air from the exhaust heating box 1115, thereby absorbing and diverting the hot air inside the asphalt delivery vehicle 11. The hot air flowing in the air guide pipe 112 is discharged to the surface of the asphalt through the heating plate 113, so that the asphalt surface is always kept in a hot asphalt state. Since the asphalt is kept in a softened state under the heating of the heating plate 113, the support frame 122 is rotated in conjunction with the motor 121, and the rolling roller 123 on the outer surface of the support frame 122 rolls on the surface of the hot asphalt to smooth the surface of the asphalt.

[0028] like Figures 3 to 6As shown, a support rod c1 is fixedly connected to the bottom surface of the material shifting sleeve 114, a sleeve c2 is movably sleeved on the outer surface of the support rod c1, a counterweight plate c3 is fixedly connected to the one side surface of the sleeve c2, a wave plate c4 is fixedly connected to the other side surface of the sleeve c2, and a speaker limiting plate c5 is fixedly connected to the bottom surface of the material shifting sleeve 114, and one end of the wave plate c4 is movably sleeved inside the speaker limiting plate c5.

[0029] When the asphalt is discharged through the material-dispensing sleeve 114, the asphalt will be laid on the two side surfaces of the wave plate c4. When the asphalt delivery vehicle 11 moves, the wave plate c4 will slide inside the asphalt. At this time, the concave and convex shapes on the outer surface of the wave plate c4 will cause the wave plate c4 to swing left and right inside the asphalt when sliding. The swinging wave plate c4 will shake off the accumulated asphalt so that the asphalt can be laid on the road surface. While the wave plate c4 is swinging, the speaker limit plate c5 is used to limit the swing angle of the wave plate c4, and the wave plate c4 is repeatedly swung left and right under the guidance of the asphalt.

[0030] Working principle: After the asphalt flows into the interior of the asphalt conveying vehicle 11, the motor on the outer surface of the support frame a1 rotates the rotating disk a2 and makes the rotating disk a2 rotate at a uniform speed. Whenever the pushing tooth a3 on the outer surface of the rotating disk a2 fits into contact with the pushing tooth 2 1110, it pushes the pulling rod 119 on the outer surface of the pushing tooth 2 1110, and makes the pulling rod 119 slide on the inner wall surface of the support shell 118 and squeeze the elastic wire 1111. When the pushing tooth a3 passes over the pushing tooth 2 1110, the squeezed elastic wire 1111 pushes the pulling rod 119 in the opposite direction. Under the continuous rotation of the rotating disk a2, the pushing treatment effect is repeated. When the pulling rod 119 slides back and forth on the inner wall of the supporting sleeve 118 and the limiting sleeve 117, the swing arm plate 1112 will swing left and right under the back and forth push of the pulling rod 119, and the swinging swing arm plate 1112 will drive the contraction rod 1113 to retract and retract, and the toggle rod 1114 repeatedly squeezes the interior of the asphalt under the left and right swing of the contraction rod 1113, so that some adhered and clumped asphalt can be loosened, and the loosened asphalt will be slowly discharged through the toggle sleeve 114. When the toggle lever 1114 is used to stir the asphalt inside the asphalt delivery vehicle 11, the hot air emitted from the asphalt inside will accumulate inside the asphalt delivery vehicle 11, and the air extraction pump 111 is used to extract air from the exhaust heating box 1115, thereby absorbing and diverting the hot air inside the asphalt delivery vehicle 11, and discharging the hot air flowing in the air guide pipe 112 onto the surface of the asphalt through the heating plate 113; since the asphalt is kept in a softened state under the heating of the heating plate 113, the second motor 121 is used to rotate the second support frame 122, and the rolling roller 123 on the outer surface of the second support frame 122 rolls on the surface of the hot asphalt, thereby rolling and leveling the surface of the asphalt; When the asphalt is discharged through the material-dispensing sleeve 114, the asphalt will be laid on the two side surfaces of the wave plate c4. When the asphalt delivery vehicle 11 moves, the wave plate c4 will slide inside the asphalt. At this time, the concave and convex shapes on the outer surface of the wave plate c4 will cause the wave plate c4 to swing left and right inside the asphalt when sliding. The swinging wave plate c4 will shake off the accumulated asphalt so that the asphalt can be laid on the road surface. While the wave plate c4 is swinging, the speaker limit plate c5 is used to limit the swing angle of the wave plate c4, and the wave plate c4 is repeatedly swung left and right under the guidance of the asphalt.
