[0002] When cracks and damage appear on the road surface, maintenance is required. Asphalt paving is generally chosen. During asphalt paving construction, the asphalt is usually in a high-temperature state. High-temperature asphalt has the characteristics of good fluidity, strong viscosity, and easy compaction.

[0003] When using a portable asphalt crack sealing cart to maintain road surfaces outdoors, the asphalt is stored inside the asphalt bucket. If it cannot be laid immediately, the asphalt temperature decreases over time and cannot be maintained at a high temperature, which will affect the asphalt paving effect. The portable asphalt crack sealing cart does not have a design to heat the asphalt inside the asphalt bucket, so it cannot maintain the temperature of the asphalt inside the bucket. When using the portable asphalt crack sealing cart for road maintenance and asphalt paving outdoors, there is a problem of not having a design to heat the asphalt inside the bucket. Therefore, this application proposes a road maintenance asphalt heating cart. Utility Model Content

[0028] Example 1

[0029] Please see Figures 1 to 4This utility model provides a technical solution: a road maintenance asphalt heating cart, including an asphalt bucket cart, comprising a cart plate 11, a support plate 12 mounted on one side surface of the cart plate 11, and a road maintenance asphalt bucket 13 mounted at the center of the support plate 12. An air outlet pipe 121 is provided on the outer surface of the support plate 12, and one end of the air outlet pipe 121 passes through a fan box 3 and is inserted into the heating chamber 2. The support plate 12, the cart plate 11, and the road maintenance asphalt bucket 13 are combined using conventional methods. The interior of the road maintenance asphalt bucket 13... The device stores asphalt; it includes a heating chamber mechanism comprising a heating chamber body 2 mounted on a trolley plate 11, and heating rods 21 installed side-by-side and equidistantly inside the heating chamber body 2. The heating chamber body 2 and the trolley plate 11 are combined using conventional methods. After power is supplied via conventional methods, the heating rods 21 are activated and generate heat, raising the temperature of the gas inside the heating chamber body 2 and providing hot air for heating; and a circulation assembly comprising a fan box 3 mounted on the trolley plate 11, a circulating fan 41 installed inside the fan box 3, and a double-pipe connected to the air inlet of the circulating fan 41. 411. A connecting pipe 42 connected to the outlet of the circulating fan 41, and a connecting pipe 43 with one end inserted into the asphalt maintenance bucket 13. The fan box 3, the trolley plate 11, and the circulating fan 41 are combined using conventional methods. After power is supplied using conventional methods, the circulating fan 41 starts and draws in the hot air inside the heating box 2, and discharges the hot air along the connecting pipe 42 and the connecting pipe 43. The hot air enters the interior of the baffle plate 51, and then the hot air is discharged from the evenly distributed heat-conducting pipes 53. The heat-conducting pipes 53 conduct heat, causing the heating pipes to... 52 Heating: The heating pipe 52 transfers heat to the asphalt inside the road maintenance asphalt bucket 13, which can heat the asphalt that has cooled down to a high temperature. The heating component includes a baffle plate 51 installed inside the road maintenance asphalt bucket 13 and connected to the connecting pipe 43, a heating pipe 52 vertical to the baffle plate 51, and a heat-conducting pipe 53 installed inside the heating pipe 52. The heating pipe 52 and the heat-conducting pipe 53 are made of thermally conductive copper alloy material, which can conduct heat to achieve the effect of heat transfer to the cooled asphalt.

[0030] In this embodiment, one end of the double-pass pipe 411 is inserted into the interior of the heating box 2. The double-pass pipe 411 connects the heating box 2 and the circulating fan 41. The interior of the baffle plate 51 is provided with an air storage chamber b that is connected to the connecting pipe 43. The connecting pipe 43 is connected to the connecting pipe 42. The hot air discharged by the circulating fan 41 enters the connecting pipe 43 from the connecting pipe 42 and then enters the interior of the baffle plate 51. The baffle plate 51 is parallel to the support plate 12, the heating pipe 52 is parallel to the connecting pipe 43, and the connecting pipe 43 is perpendicular to the baffle plate 51.

[0031] In this embodiment, the support plate 12 is provided with an air storage cavity a. The two ends of the heat conduction pipe 53 are connected to the air storage cavity a and the air storage cavity b, respectively. The heat conduction pipe 53 includes straight round pipes at both ends and a spiral pipe at the center. The middle position of the heat conduction pipe 53 is spiral-shaped, which can extend the airflow channel and allow heat to dissipate between the heat conduction pipe 53 and the heating pipe 52, and finally achieve the function of heat conduction to the heating pipe 52.

[0032] In this embodiment, a feed pipe 131 is provided on the side of the top of the road maintenance asphalt bucket 13, which facilitates the replenishment of asphalt into the road maintenance asphalt bucket 13. A pull plate 412 is slidably connected to the blower box 3, which can be pulled outward to facilitate observation of the status of the circulating blower 41 inside the blower box 3.

[0033] The steps for heating the asphalt inside the asphalt tank 13 for road maintenance are as follows:

[0034] After power is supplied by conventional methods, heating rod 21 starts and heats up, the temperature of the gas inside heating chamber 2 rises, and hot air is provided for heating.

[0035] After power is supplied by conventional methods, the circulating fan 41 starts and draws in the hot air inside the heating chamber 2, and discharges the hot air along the connecting pipe 42 and the connecting pipe 43.

[0036] Hot air enters the interior of the baffle plate 51 along the connecting pipe 42 and the connecting pipe 43, and then the hot air is discharged from the evenly distributed heat-conducting pipe 53 into the interior of the support plate 12.

[0037] The hot air inside the heat pipe 53 conducts heat to the heat pipe 53, and the heat pipe 53 conducts heat. The middle part of the heat pipe 53 is spiral-shaped, which can extend the airflow channel and allow heat to dissipate between the heat pipe 53 and the heating pipe 52. Finally, the heat is conducted to the heating pipe 52, which heats the heating pipe 52. The heated heating pipe 52 transfers heat to the asphalt inside the road maintenance asphalt bucket 13, which can heat the asphalt that has cooled down and bring it to a high temperature.

[0038] The hot air from the support plate 12 enters the heating chamber 2 through the air outlet pipe 121 and is then drawn in by the circulating fan 41 to complete the hot air circulation.

[0039] In summary: The asphalt crack sealing cart does not have a design to heat the asphalt inside the asphalt bucket. The heating rod 21 is activated and generates heat, raising the temperature of the gas inside the heating box 2 and providing hot air for heating. The circulating fan 41 draws in the hot air, which travels along the connecting pipe 42, the connecting pipe 43, and the baffle plate 51 into the heat conduction pipe 53. The heat dissipates between the heat conduction pipe 53 and the heating pipe 52, and finally, the heat is conducted to the heating pipe 52, causing it to heat up. The heated heating pipe 52 then transfers heat to the asphalt inside the road maintenance asphalt bucket 13, which can reheat the cooled asphalt to a high temperature.

[0040] Example 2

[0041] Please see Figures 1 to 7 This is the second embodiment of the present invention. Based on the previous embodiment, in order to increase the dustproof effect, a protective component is provided inside the heating chamber 2. The dustproof component includes a partition 22, inclined baffles 23 installed on both ends of the partition 22, and a mesh 24 adhered to the surface of the baffle 23. The partition 22 is combined with the heating chamber 2 and the baffle 23 by conventional methods. An air inlet is provided on the outer surface of the heating chamber 2. The partition 22 has a mesh structure, and the baffle 23 and the mesh 24 are right-angled trapezoids. When external air enters the interior of the heating chamber 2, the gas first falls on the baffle 23 and is filtered by the mesh 24, and then the gas falls into the interior of the heating chamber 2. The mesh partition 22 also plays a filtering role, preventing impurities contained in the incoming air from adhering to the surface of the heating rod 21.

[0042] In this embodiment, a vent hole 231 is provided on the surface of the baffle 23. The opposite surfaces of the baffle 23 are surface layer c and surface layer d, respectively. The vent hole 231 is a conical shape with one end wider than surface layer c and the other end narrower than surface layer d. The vent hole 231 plays a role in diverting the flow, allowing the gas to disperse through the baffle 23, which is beneficial for filtering large particulate impurities contained in the air.

[0043] In summary: When air enters the heating chamber 2, the gas first falls on the baffle 23 and is filtered by the mesh 24, and then the gas falls into the heating chamber 2. The mesh baffle 22 also plays a filtering role, preventing impurities in the incoming air from adhering to the surface of the heating rod 21, thus having a dustproof effect.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
