[0005] In some embodiments, the asphalt tank includes an outer insulation box and an inner cylinder, wherein the inner cylinder is provided with heating wires; The top of the inner cylinder is connected to the bottom of the fire extinguishing box, and a temperature detector is also installed at the bottom of the inner cylinder.

[0006] In some embodiments, a partition is provided at the bottom of the outer insulation box below the inner cylinder, and a motor is provided inside the partition. The output end of the motor extends through the partition into the inner cylinder and is connected to a stirring blade.

[0007] In some embodiments, the fire extinguishing box includes a box body, the interior of which is provided with a vertical partition, one side of which is an electromagnetic compartment and the other side is a soil storage compartment.

[0008] In some embodiments, the inner wall of the soil storage chamber is hinged with a rotatable lower baffle, the partition is hinged with an upper baffle that is offset from the lower baffle, and the interior of the electromagnetic chamber is provided with an electromagnetic mechanism that cooperates with the lower baffle to open or close.

[0009] In some embodiments, a pull rope is fixedly connected to one end of the lower baffle; In normal operation, the electromagnetic mechanism presses the pull rope and pulls the lower baffle, causing the lower baffle to engage with the upper baffle to close. When the fire is extinguished, the electromagnetic mechanism releases the pull rope, and the lower baffle separates from the upper baffle under gravity.

[0010] In some embodiments, the pull cord has a double-layer structure; the inner core is a fusible core, and the outer layer is an aramid layer.

[0011] In some embodiments, a magnetic block is provided at the end of the upper surface of the lower baffle, and a magnet that is magnetically attracted to the magnetic block is provided at the end of the lower surface of the upper baffle.

[0014] Compared with the prior art, the present invention provides a municipal road crack filler with the following advantages.

[0015] 1. This utility model uses a heating wire and a double-layer asphalt tank to heat the asphalt inside; at the same time, the motor drives the stirring blades to stir the asphalt, and the asphalt is heated evenly during stirring to prevent it from solidifying.

[0016] 2. This utility model uses a soil storage compartment inside the fire extinguishing box to store a large amount of soil. When the temperature detector detects an excessively high temperature, it triggers the fire extinguishing operation, causing the soil to fall onto the asphalt in the inner cylinder to extinguish the fire. When the asphalt inside catches fire, the pull rope will also break, causing the lower baffle to rotate downwards and cover the asphalt with soil. This dual-trigger fire extinguishing structure realizes the function of automatic fire extinguishing, ensuring the safety of the equipment and the operators during production.

[0017] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-6 A municipal road crack filler includes a trolley 1, on which an asphalt tank 2, an equipment box 3, and a handle 4 are mounted.

[0027] Among them, the handle 4 is located at one end of the upper surface of the cart 1, the equipment box 3 is located on one side of the handle 4, and the asphalt box 2 is located on one side of the equipment box 3.

[0028] Furthermore, a fire extinguishing box 5 is hinged to the top of the asphalt tank 2; the fire extinguishing box 5 is flip-up, and a top cover is provided on the top of the fire extinguishing box 5.

[0029] Meanwhile, a material pump 6 for extracting asphalt is installed on the upper surface of the equipment box 3, and a bellows 7 is installed at the output end of the material pump 6. A power supply mechanism 30 is installed inside the equipment box 3.

[0030] The fire extinguishing box 5 is mounted on top of the asphalt tank 2 via a hinged design, allowing the fire extinguishing box 5 to be opened to add asphalt into the asphalt tank 2; at the same time, the top of the fire extinguishing box 5 is equipped with a top cover, which allows soil to be added inside; the power supply mechanism 30 inside the equipment box 3 provides power to the material pump 6 and the electrical appliances inside the asphalt tank 2.

[0031] During operation, the material pump 6 draws asphalt from inside the asphalt tank 2 and sprays it out from the corrugated pipe 7. The corrugated pipe 7 is then aligned with the road cracks to fill them.

[0032] In some embodiments, the asphalt box 2 includes an outer insulation box 21, and an inner cylinder 22 is provided inside the outer insulation box 21. Heating wires 26 are provided on both sides of the inner cylinder 22.

[0033] Furthermore, a partition 23 is provided at the bottom of the outer insulation box 21 below the inner cylinder 22. A motor 24 is installed inside the partition 23. The output end of the motor 24 extends through the partition 23 into the inner cylinder 22 and is connected to a stirring blade 25.

[0034] The top of the inner cylinder 22 is connected to the bottom of the fire extinguishing box 5. A temperature detector 8 is also installed at the bottom of the inner cylinder 22 to monitor the temperature of the asphalt in real time.

[0035] In this configuration, the asphalt tank 2 is divided into inner and outer layers, and upper and lower layers; the outer insulation box 21 can ensure that heat is not lost in large quantities and avoid affecting the surrounding temperature; the motor 24 can drive the stirring blade 25 to rotate, so that the asphalt is evenly stirred in the inner cylinder 22.

[0036] In addition, the temperature detector 8 can detect the temperature of the inner cylinder 22 in real time, and automatically start the fire extinguishing operation when the temperature is too high or exceeds the preset value.

[0037] In some embodiments, the power supply mechanism 30 includes a generator 31, a battery 32, and a control switch 33.

[0038] Preferably, the control switch 33 is located on the side of the equipment box 3, the generator 31 is located on one side of the control switch 33, and the battery 32 is located between the generator 31 and the control switch 33.

[0039] Control switch 33 is electrically connected to generator 31 and battery 32 respectively, and is also electrically connected to temperature detector 8. Generator 31 can generate electricity, which is then used to charge battery 32 through inverter; in addition to the switch module, control switch 33 also includes protection circuit and control chip, used to control all electrical equipment.

[0040] In some embodiments, the feed end of the material pump 6 is provided with an extraction pipe 61, which passes through the outer insulation box 21 and extends into the inner cylinder 22; the material pump 6 extracts asphalt and works with the corrugated pipe 7 to fill the cracks.

[0041] In some embodiments, the fire extinguishing box 5 includes a box body 51, and the inside of the box body 51 is provided with a vertical partition 52. One side of the partition 52 is an electromagnetic compartment 53, and the other side is a soil storage compartment 54.

[0042] The inner wall of the soil storage chamber 54 is hinged with a rotatable lower baffle 55, and the partition 52 is hinged with an upper baffle 56 that is vertically offset from the lower baffle 55. The electromagnetic chamber 53 is equipped with an electromagnetic mechanism 57 that works in conjunction with the lower baffle 55 to open or close.

[0043] The soil storage chamber 54 contains a large amount of soil for extinguishing open flames of asphalt. When the temperature of the inner cylinder 22 is too high or there are a large number of open flames, the electromagnetic mechanism 57 is triggered, causing the lower baffle 55 to rotate and the soil to fall into the inner cylinder 22.

[0044] In some embodiments, a pull rope 577 is fixedly connected to one end of the lower baffle 55.

[0045] In normal operation, the electromagnetic mechanism 57 presses the pull rope 577 and pulls the lower baffle 55, causing the lower baffle 55 to close in conjunction with the upper baffle 56. When the fire is extinguished, the electromagnetic mechanism 57 releases the pull rope 577, and the lower baffle 55 separates from the upper baffle 56 under gravity.

[0046] In some embodiments, a magnetic block 58 is provided at the end of the upper surface of the lower baffle 55, and a magnet 59 that is magnetically attracted to the magnetic block 58 is provided at the end of the lower surface of the upper baffle 56.

[0047] Furthermore, a sealing gasket is provided on the opposite surfaces of magnets 59 and magnets 59.

[0048] The soil is stored above the lower baffle 55 and the upper baffle 56. To prevent the soil from leaking down, the lower baffle 55 and the upper baffle 56 are sealed by the attraction of the magnet 59 and the magnetic block 58, so that the gap between the lower baffle 55 and the upper baffle 56 is sealed.

[0049] Understandably, when the fire extinguishing operation is triggered, the lower baffle 55 and the upper baffle 56 can overcome the magnetic force of the magnet 59 and the magnetic block 58 and separate under the action of gravity above.

[0050] It should be noted that the lower baffle 55 and the upper baffle 56 are staggered vertically, forming a double-door structure; the end of the upper baffle 56 rests on top of the end of the lower baffle 55.

[0051] In some embodiments, the pull cord 577 has a double-layer structure.

[0052] The inner core is a fusible core, and the outer layer is an aramid layer; the inner core can use polyester fiber with a melting point of 250℃.

[0053] The heating temperature of asphalt is generally between 140℃ and 180℃. When the temperature exceeds 250℃, the inner core of the pull rope 577 will melt. After melting, the excessive weight of the soil and the high temperature will break the outer aramid layer, causing the pull rope 577 to break completely, thus avoiding the high temperature and open flame of the asphalt.

[0054] In normal conditions, the lower baffle 55 is held in place by the pull rope 577; after the pull rope 577 breaks, the lower baffle 55 will no longer be under force and will be opened due to the rotation of a large amount of soil above.

[0055] In some embodiments, the pull cord 577 is connected to the positioning ring 576, and the electromagnetic mechanism 57 presses down to lock the positioning ring 576, making installation easier.

[0056] The positioning ring 576 holds the lower baffle 55 by the pull rope 577. When the electromagnetic mechanism 57 releases the positioning ring 576 or the pull rope 577 breaks, the lower baffle 55 is no longer under force, and due to the rotation of a large amount of soil above, it becomes open.

[0057] In some embodiments, the electromagnetic mechanism 57 includes: a fixing block 571 fixedly disposed in the electromagnetic chamber 53; a push-pull electromagnet 572 is disposed on the fixing block 571, the output axis of the push-pull electromagnet 572 extends downward, and a clamping plate 573 is fixedly mounted thereon.

[0058] Meanwhile, a support plate 574 connected to the inner wall of the electromagnetic compartment 53 is fixedly installed below the push-pull electromagnet 572; a positioning ring 576 is clamped between the clamping plate 573 and the support plate 574; and the output shaft of the push-pull electromagnet 572 passes through the positioning ring 576 and the support plate 574.

[0059] In addition, a pressure spring 575 is fitted on the upper section of the output shaft of the push-pull electromagnet 572; under normal conditions, the push-pull electromagnet 572 is not powered, and the pressure spring 575 presses down the clamping plate 573 to lock the positioning ring 576.

[0060] It should be noted that the output shaft of the push-pull electromagnet 572 is downward. When not energized, the output shaft is in an extended state. When energized, the output shaft and the pressure spring 575 retract. The two ends of the pressure spring 575 press against the lower end of the push-pull electromagnet 572 and the upper end of the clamping plate 573, respectively.

[0061] When the power is off (no power supply), the output shaft passes through the support plate 574 and locks the positioning ring 576; after the power is turned on, the output shaft retracts and disengages from the positioning ring 576, causing the positioning ring 576 to slide out and release the pull rope 577; the lower baffle 55 is pressed down by the gravity of the soil, causing the soil to fall onto the asphalt, completing the soil fire extinguishing.

[0062] When the temperature detector 8 detects an excessively high temperature or exceeds a predetermined temperature, the fire extinguishing operation is triggered, activating the push-pull electromagnet 572 and disengaging the positioning ring 576. Simultaneously, the push-pull electromagnet 572 can also be manually activated (by setting a trigger switch). Alternatively, if there is an open flame in the inner cylinder 22, the pull rope 577 will break under the combined effects of fire and gravity. Fire extinguishing can be activated in either of these situations.

[0063] When using this device, the fire extinguishing box 5 must first be opened, and paving asphalt must be added into the inner cylinder 22. Then, the fire extinguishing box 5 must be closed, and a large amount of soil must be added to the soil storage compartment 54 of the fire extinguishing box 5 for fire extinguishing. When the asphalt needs to be heated, the heating wire 26 is activated to heat it, while the motor 24 drives the stirring blade 25 to rotate. Asphalt is drawn out by the material pump 6 and sprayed out from the corrugated pipe 7, which is then used to fill cracks. If the temperature of the asphalt inside the inner cylinder 22 is too high, it will be detected by the temperature detector 8, and then automatically... Activating the push-pull electromagnet 572 causes the positioning ring 576 to disengage from the electromagnet 572. The lower baffle 55 is no longer under force, and the large amount of soil above it rotates, covering the burning asphalt and extinguishing the fire. When a large amount of open flame appears inside the inner cylinder 22, the pull rope 577 breaks, also causing the lower baffle 55 to lose force, allowing soil to cover the asphalt and extinguish the fire. Both methods and fire extinguishing mechanisms are automatic, ensuring the safety of the equipment and operators during production.
