Description

[0002] Asphalt caulking machines are usually used to repair cracked asphalt pavements to prevent further cracking and damage to the roadbed. At present, when maintaining and repairing asphalt pavements, it is necessary to first use a cutting machine to expand the cracks in the pavement, and then use a vacuum device to clean the dust and impurities around and in the cracks, and then use the asphalt caulking machine to pour sealant into the cracks and fill the cracks to achieve road repair operations. The asphalt caulking machine of the prior art requires that the block of sealant be placed in the caulking machine and heated, and then used after it is melted, but the newly placed sealant After melting, it will mix with the sealant inside the original caulking machine, and the sealant inside the original caulking machine was not used up last time, and has been heated once during the last use. After the original sealant is mixed with the newly added sealant, if it is heated a second time and not used up, the subsequent heating and use will cause the original sealant to be modified, thereby reducing the quality of the overall sealant in the caulking machine, and then resulting in a decrease in durability after road repair, which cannot meet the expected requirements of the project.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention provides a material receiving trough, a guide plate and an ultrafiltration membrane, opens a sealing cover, and places two pieces of sealant in the material receiving trough respectively, so that the sealant contacts the inner wall of the material receiving trough. Due to the heat generated by the heating plate 1, the two pieces of sealant can be heated and the sealant can be gradually melted. The melted liquid sealant will flow down to the guide plate, and then pass through the guide plate and the heat conductive filter screen and fall onto the ultrafiltration membrane below the heat conductive filter screen. Due to the operation of the power motor, the rotating shaft, the ultrafiltration membrane and the flip plate can be driven to rotate, and the sealant can be carried to rotate to the bottom of the fixed pipe, so that the sealant flows into the bottom of the inner cavity of the heating barrel through the inclined surface block. This design can prevent the newly introduced sealant from floating up due to the low temperature, and will not generate hot and cold convection, thereby avoiding the mixing of the new sealant and the original sealant, and then forming a layer, which is convenient for distinguishing the new sealant from the original sealant, and also convenient for the subsequent priority use of the original sealant.

[0017] 2. The present invention sets a fixed tube and a through hole. Due to the operation of the air pump, the gas in the upper air chamber inside the fixed tube can be extracted through the air inlet pipe, and negative pressure is formed inside the guide plate and the material trough through the through hole and the ultrafiltration membrane, and the downward flow of the sealant on the guide plate is accelerated. At the same time, the extracted gas is discharged into the air chamber below the fixed tube through the air outlet pipe, so that positive pressure is formed below the fixed box, and the rubber baffle is opened, thereby accelerating the flow rate of the sealant, and the residual sealant inside the fixed box and the guide plate can be cleaned by positive and negative pressure, so as to avoid the sealant remaining inside the fixed box and the guide plate due to its own viscosity, and avoid the waste of sealant and the problem of repeated thermal modification of residual colloid.

[0018] 3. The present invention provides a floating plate and a suction head. Due to the operation of the sealing pump, the sealant at the highest liquid level inside the heating barrel can be extracted through the extraction pipe, the installation pipe, the connecting pipe, the round pipe and the suction head, and the sealant can be sprayed into the asphalt cracks through the caulking pipe to achieve the effect of asphalt pavement repair. Since the floating plate floats on the sealant liquid level, the round pipe, the connecting pipe and the suction head can be always at the highest point of the current liquid level, and the slider can move up and down on the slide rail, and can drive the round pipe, the connecting pipe and the suction head to move, so that the suction head can move with the ups and downs of the floating plate, ensuring that the suction head can always extract the sealant at the highest point of the current liquid level inside the heating barrel. At the same time, the entry of new sealant will be located below the inner cavity of the heating barrel and stratified with the original sealant. The original sealant stratification will float above the new sealant because its temperature is higher than that of the new sealant, so that the suction head can preferentially extract and use the original sealant to form a sequence, thereby avoiding the problem of the original sealant remaining again and causing repeated thermal modification, improving the quality of the sealant, and further improving the durability of the road after repair.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figures 1 to 15 As shown, the present invention provides an asphalt caulking machine for road paving, comprising a carrier 1, a generator 2, a heating component 3 and a caulking component 4;

[0037] The generator 2 is arranged on the carrier 1, the heating component 3 is arranged on the carrier 1 and is connected to the circuit of the generator 2, and the caulking component 4 is installed on the heating component 3 and is connected to the circuit of the generator 2;

[0038] The heating assembly 3 includes a heating barrel 31, which is mounted on the carrier 1. A sealing cover 32 is hinged on the top of the heating barrel 31. Both sides of the top of the sealing cover 32 are fixedly connected to a ventilation assembly 33. A heating rack 34 is installed above the inside of the sealing cover 32. Both sides of the inside of the heating rack 34 are provided with a material trough 35. A heating plate 1 36 is installed inside the heating rack 34 and can heat the inside of the material trough 35. A guide plate 37 is fixedly connected to the bottom of the heating rack 34. A partition plate 38 located below the guide plate 37 is installed inside the heating barrel 31. A heating plate 2 39 is installed inside the partition plate 38. The top is connected to the guide plate 37, the interior of the heating barrel 31 is equipped with a heat conducting plate 310 which can be connected to the right side of the partition plate 38, the interior of the heat conducting plate 310 is equipped with a heat conducting filter 311, the interior of the heating barrel 31 is equipped with a fixed box 312 which can communicate with the heat conducting filter 311, a power motor 316 is installed on the outside of the heating barrel 31, the power motor 316 is driven and connected with a rotating shaft 317, the other end of the rotating shaft 317 extends to the interior of the heating barrel 31 and is connected with four flip plates 319 arranged in a surrounding manner, an ultrafiltration membrane 318 is connected between each flip plate 319, and a heating plate three 320 is installed at the bottom of the interior of the heating barrel 31.

[0039] The above scheme is adopted: the sealing cover 32 is opened, and two pieces of sealant are placed inside the material tank 35 respectively, so that the sealant contacts the inner wall of the material tank 35. Due to the heating of the heating plate 36, the two pieces of sealant can be heated and the sealant is gradually melted. The melted liquid sealant will flow down to the guide plate 37, and then pass through the guide plate 37 through the heat-conducting filter 311 and fall onto the ultrafiltration membrane 318 below the heat-conducting filter 311. Due to the operation of the power motor 316, the rotating shaft 317, the ultrafiltration membrane 318 and the flip plate 319 can be driven to rotate, and the sealant is carried to rotate to the bottom of the fixed tube 3151, so that the sealant flows into the bottom of the inner cavity of the heating barrel 31 through the inclined block 313. At this time, the newly fed sealant will not float up due to the low temperature, and will not generate hot and cold convection, so as to avoid mixing the new sealant with the original sealant, thereby forming a layer, and at the same time, it is convenient to use the original sealant first in the subsequent process.

[0040] Due to the design of the ultrafiltration membrane 318, it can block and isolate the sealant without blocking the gas;

[0041] Due to the heat generated by the heating plate 39, the heat can be conducted to the thermal filter 311 through the heat conducting plate 310. The design of the thermal filter 311 can prevent the sealing rubber blocks that have not melted in time from falling onto the ultrafiltration membrane 318 under the thermal filter 311, and the thermal filter 311 can heat the sealing rubber blocks that have not melted in time, so that they can melt and then fall onto the ultrafiltration membrane 318.

[0042] like Figure 2 , Figure 4 , Figures 7 to 10 As shown, the interior of the heating barrel 31 is installed with a pneumatic assembly 315 located on the inner side of the ultrafiltration membrane 318. The pneumatic assembly 315 includes a fixed tube 3151, which is connected to the heating barrel 31. The upper and lower parts of the interior of the fixed tube 3151 are divided into two relatively independent air chambers. The upper and lower parts of the fixed tube 3151 are both provided with a plurality of through holes 3152.

[0043] The above scheme is adopted: by setting a fixed tube 3151, when the upper air chamber inside the fixed tube 3151 is at negative pressure, negative pressure can be formed inside the guide plate 37 and the material trough 35 through the through hole 3152 and the ultrafiltration membrane 318, and the downward flow of the sealant on the guide plate 37 is accelerated. When the lower air chamber inside the fixed tube 3151 is at positive pressure, positive pressure is formed below the fixed box 312, and the rubber baffle 314 is opened, thereby accelerating the flow rate of the sealant.

[0044] like Figure 2 , Figure 4 , Figures 7 to 10 As shown, a support frame 3155 is connected to the outer side of the heating barrel 31, and an air pump 3156 is installed on the outer side of the support frame 3155. An air inlet pipe 3153 is connected to the upper side of one side of the air pump 3156, and the other end of the air inlet pipe 3153 extends to the interior of the heating barrel 31 and is connected to the fixed pipe 3151. One side of the air pump 3156 is connected to an air outlet pipe 3154 located below the air inlet pipe 3153, and the other end of the air outlet pipe 3154 extends to the interior of the heating barrel 31 and is connected to the fixed pipe 3151.

[0045] The above scheme is adopted: by setting the air inlet pipe 3153 and the through hole 3152, due to the operation of the air pump 3156, the gas in the upper air chamber inside the fixed tube 3151 can be extracted through the air inlet pipe 3153, and the inside of the guide plate 37 and the material trough 35 is formed with a negative pressure through the through hole 3152 and the ultrafiltration membrane 318. At the same time, the extracted gas is discharged into the lower air chamber inside the fixed tube 3151 through the air outlet pipe 3154, so that a positive pressure is formed below the fixed box 312.

[0046] like Figure 3As shown, the ventilation assembly 33 includes a ventilation pipe 331, which is connected to the sealing cover 32. A dustproof net 333 is installed above the interior of the ventilation pipe 331, and a one-way valve 332 located below the dustproof net 333 is installed inside the ventilation pipe 331.

[0047] The above scheme is adopted: by setting a one-way valve 332 and a dustproof net 333, due to the design of the one-way valve 332, the interior of the heating barrel 31 can be sealed without being affected by negative pressure, and due to the dustproof net 333, the entry of impurities and dust in the air can be blocked.

[0048] like Figure 2 and Figure 4 As shown, a rubber stopper 314 is connected to the bottom of the data partition plate 38 , and a slope block 313 is connected to the lower left side of the fixed box 312 , and the other side of the slope block 313 abuts against the rubber stopper 314 .

[0049] The above scheme is adopted: by setting a rubber baffle 314, when the rubber baffle 314 abuts against the inclined block 313, the interior of the fixed box 312 can be sealed, and when the rubber baffle 314 is opened due to the influence of positive pressure, the interior of the fixed box 312 can be connected with the inner cavity of the heating barrel 31, and at the same time, the sealant in the inner cavity of the heating barrel 31 will not enter the interior of the fixed box 312 due to the influence of positive pressure, but the sealant inside the fixed box 312 can be delivered into the inner cavity of the heating barrel 31.

[0050] like Figure 2 , Figure 5 and Fig.15 As shown, the caulking assembly 4 includes a caulking pump 41, which is installed on the outside of the heating barrel 31. One side of the caulking pump 41 is connected to a suction pipe 42, and the other end of the suction pipe 42 is connected to a solenoid valve 43 installed on the heating barrel 31. The other side of the caulking pump 41 is connected to a caulking pipe 44.

[0051] The above scheme is adopted: by setting up a grouting pipe 44, due to the operation of the sealing pump 41, the highest liquid level of the sealant inside the heating barrel 31 can be extracted through the extraction pipe 42, the installation pipe 45, the connecting pipe 49, the circular pipe 410 and the suction head 411, and it is sprayed into the asphalt cracks through the grouting pipe 44 to achieve the effect of repairing the asphalt pavement.

[0052] like Figure 2 , Figure 5 , Fig.11 and Fig.12As shown, a mounting tube 45 is connected to the left side of the inner cavity of the heating barrel 31, a slide rail 47 is connected to the inner side of the mounting tube 45, a movable groove 46 is opened on the other side of the mounting tube 45, a slider 48 is slidably installed on the outer surface of the slide rail 47, a connecting tube 49 is fixedly sleeved inside the slider 48, the other end of the connecting tube 49 passes through the movable groove 46 and extends to the interior of the heating barrel 31 and is connected to a round tube 410, a floating plate 412 is installed on the top of the round tube 410, and suction heads 411 are connected to both ends of the round tube 410.

[0053] The above scheme is adopted: by setting a floating plate 412, due to the design of the floating plate 412, the circular tube 410, the connecting tube 49 and the suction head 411 can always be at the highest point of the current liquid level, and the slider 48 can move up and down on the slide rail 47, and at the same time can drive the circular tube 410, the connecting tube 49 and the suction head 411 to move, so that the suction head 411 can move with the ups and downs of the floating plate 412, ensuring that the suction head 411 can always extract the sealant at the highest point of the current liquid level inside the heating barrel 31.

[0054] like Figure 2 , Figure 5 and Figure 6 As shown, an active cavity 414 is opened at the bottom of the heating barrel 31 and inside the carrier 1 , and a sealing plate 413 that can cover the active groove 46 is fixedly sleeved on the outer surface of the connecting pipe 49 , and the bottom of the sealing plate 413 extends to the inside of the active cavity 414 .

[0055] The above solution is adopted: by setting a sealing plate 413, due to the design of the sealing plate 413, a good blocking effect can be achieved on the movable groove 46, so that the movable groove 46 can provide a movable space for the connecting pipe 49, and at the same time, the sealing plate 413 can block the sealant in the inner cavity of the heating barrel 31 from passing through the movable groove 46 and entering the interior of the mounting tube 45.

[0056] like Fig.15 As shown, the outer side of the extraction pipe 42 is fixedly connected to a return pipe 415 , and the other end of the return pipe 415 is connected to a solenoid valve 416 installed on the heating barrel 31 .

[0057] The above scheme is adopted: after use, the solenoid valve 1 43 is closed, the solenoid valve 2 416 is opened, and the bidirectional function of the sealing pump 41 is used to work in reverse, and the sealant inside the caulking tube 44 and the sealant inside the extraction tube 42 are pumped back to the interior of the heating barrel 31 through the reflux pipe 415 to prevent the residual sealant from clogging the caulking tube 44 and the extraction tube 42.

[0058] The working principle and use process of the present invention:

[0059] When in use, the operator opens the sealing cover 32 and places two pieces of sealant inside the material trough 35 respectively, so that the sealant contacts the inner wall of the material trough 35. Due to the operation of the generator 2, the heating plate 1 36, the heating plate 2 39 and the heating plate 3 320 can be heated. When the heating plate 3 320 is heated, the original sealant inside the heating barrel 31 will be heated and melted to reach the standard for use. At the same time, after the original sealant inside the heating barrel 31 is melted, the floating plate 412 will not be fixed by the solidification of the sealant. Due to the heating of the heating plate 1 36, the two pieces of sealant can be heated and gradually melted. The melted liquid sealant will flow down to the guide plate 37, and the heating process will only melt the sealant blocks and flow out in liquid form, and will not be further heated to reach the standard for use. The temperature of the newly added sealant will be lower than the temperature of the original sealant in the heating barrel 31.

[0060] When the temperature of the original sealant inside the heating barrel 31 reaches the standard for use, the solenoid valve 43 opens. Due to the operation of the sealing pump 41, the sealant at the highest liquid level inside the heating barrel 31 can be extracted through the extraction pipe 42, the installation pipe 45, the connecting pipe 49, the round pipe 410 and the suction head 411, and it is sprayed into the asphalt cracks through the caulking pipe 44 to achieve the effect of repairing the asphalt pavement. At the same time, due to the operation of the air pump 3156, the gas in the upper air chamber inside the fixed pipe 3151 can be extracted through the air inlet pipe 3153, and negative pressure is formed inside the guide plate 37 and the material tank 35 through the through hole 3152 and the ultrafiltration membrane 318, and the downward flow of the sealant on the guide plate 37 is accelerated, so that it passes through the thermal filter 311 and falls onto the ultrafiltration membrane 318 between the flip plates 319 below the thermal filter 311, and the extracted gas is passed through the outlet pipe 3154 It is discharged into the air chamber at the bottom of the fixed tube 3151, so that positive pressure is formed at the bottom of the fixed box 312, and the rubber baffle 314 is stretched open. Due to the operation of the power motor 316, the rotating shaft 317, the ultrafiltration membrane 318 and the flip plate 319 can be driven to rotate, and the sealant is carried to the bottom of the fixed tube 3151, so that the sealant is affected by the positive pressure and quickly sent to the bottom of the inner cavity of the heating barrel 31 through the inclined block 313. At this time, the newly-sent sealant will not float up due to its low temperature, and will not produce hot and cold convection, thereby avoiding the mixing of the new sealant and the original sealant, and then forming a layer, which is convenient for distinguishing the new sealant from the original sealant. At the same time, it is also convenient for the subsequent priority use of the original sealant to form a sequence, avoiding the problem of the original sealant remaining again and causing repeated heat modification, thereby improving the quality of the sealant and further improving the durability of the road after repair.

[0061] Since the float plate 412 floats on the sealant liquid level, the circular tube 410, the connecting tube 49 and the suction head 411 can be always at the highest point of the current liquid level, and the slider 48 can move up and down on the slide rail 47, and at the same time can drive the circular tube 410, the connecting tube 49 and the suction head 411 to move, so that the suction head 411 can move with the ups and downs of the float plate 412, to ensure that the suction head 411 can always extract the sealant at the highest point of the current liquid level inside the heating barrel 31, and at the same time, the new sealant will enter below the inner cavity of the heating barrel 31 and be stratified with the original sealant, and the original sealant stratification will float above the new sealant because the temperature is higher than the new sealant, so that the suction head 411 can preferentially extract and use the original sealant to avoid the original sealant remaining again.

[0062] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
