Description

Technical Field

[0001] This utility model relates to the field of road maintenance technology, and in particular to an extruder for road surface crack sealing material. Background Technology

[0002] In road maintenance, pavement cracks are a common problem. If not treated in time, they can easily lead to rainwater seeping into the roadbed and damaging the pavement structure. Therefore, they need to be sealed and repaired through grouting operations. A pavement crack grouting material extruder is a core piece of equipment. Its main function is to heat asphalt, resin and other grouting materials to a suitable flow state and then precisely extrude them into the cracks to achieve filling and sealing, thereby extending the road life and reducing maintenance costs. This equipment is widely used in municipal roads, highways, rural roads and other scenarios. Its performance stability and operation efficiency directly affect the maintenance quality and construction progress.

[0003] Existing road crack sealing material extruders mostly use liquefied petroleum gas (LPG) to directly heat the sealing material. The mechanical structure includes a sealing cylinder, an LPG burner, a manual stirring rod, and a gear conveying mechanism. The LPG burner is installed at the bottom or lower side of the cylinder. After ignition, it generates a flame that directly heats the outer wall of the cylinder. The heat is conducted to the material inside the cylinder through the cylinder wall. The manual stirring rod runs through the top of the cylinder and needs to be rotated by the operator periodically to simply mix the material and avoid local overheating. After the material is heated to a preliminary flowable state, the gear conveying mechanism pushes the material to the metal nozzle through meshing extrusion pressure, and finally extrudes it into the crack to complete the sealing. Its technical principle is the combination of the heat release from the combustion of liquefied gas and mechanical extrusion conveying, relying on flame energy and gear transmission to achieve material conveying and sealing.

[0004] However, the combination of direct heating with liquefied gas and simple manual stirring in the existing technology makes it difficult to achieve uniform heating of the potting material: the heat of the flame is concentrated in the contact area of ​​the barrel, where the material is prone to coking and denaturation due to excessive temperature, resulting in deterioration of performance and reduced adhesion, which fails to meet the sealing requirements. Meanwhile, the material in the barrel far from the heating area has insufficient heat, resulting in a low temperature and poor fluidity. This not only easily causes the gear conveying mechanism to jam and reduces the conveying efficiency, but also causes the material to fail to fully fill the cracks after extrusion, resulting in potting gaps and poor sealing, which seriously affects the quality of potting construction and the long-term durability of the road. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a road crack sealing material extruder, which aims to improve the problem that traditional equipment is difficult to heat the sealing material evenly, which can easily lead to the sealing material becoming coking and deformed when the temperature is too high or the fluidity deteriorates when the temperature is too low.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a road crack sealing material extruder, comprising a shell, a base plate fixedly connected to the lower surface of the shell, an mounting plate fixedly connected to the upper surface of the base plate, a sealing material barrel fixedly connected to the upper surface of the mounting plate, a conveying pump fixedly connected to the upper surface of the mounting plate, a guide pipe three fixedly connected to the input end of the conveying pump, a guide pipe four fixedly connected to the output end of the conveying pump, a filling gun fixedly connected to one end of the guide pipe four, a heating component provided on the upper surface of the mounting plate, and a connecting component provided at one end of the filling gun; The heating assembly includes a heating platform, the lower surface of which is disposed on the upper surface of a mounting plate. An oil tank is disposed on the upper surface of the heating platform. A guide pipe is fixedly connected to the inner wall of the oil tank. A hydraulic pump is disposed above the mounting plate. The input end of the hydraulic pump is fixedly connected to one end of the guide pipe, and the output end of the hydraulic pump is fixedly connected to one end of the guide pipe. A guide pipe is attached to the outer wall of the filling material tank. A motor is disposed on the upper surface of the filling material tank, and an auger is fixedly connected to the output end of the motor.

[0007] Furthermore, the connecting assembly includes a first flange, the inner wall of which is fixedly connected to one end of the filling gun; a second flange is attached to the outer wall of the first flange; a nozzle is fixedly connected to the inner wall of the second flange; a pin is slidably connected to the inner walls of the first and second flanges; a rotating rod is fixedly connected to one end of the pin; a groove is provided at the other end of the pin; and an elastic sheet is fixedly connected to the outer wall of the second flange.

[0008] Furthermore, a front wheel is provided on the outer wall of the base plate, and a rear wheel is provided on the outer wall of the base plate.

[0009] Furthermore, a push rod is fixedly connected to the upper surface of the base plate, and a control console is fixedly connected to the inner wall of the push rod.

[0010] Furthermore, a heat dissipation plate is fixedly connected to the inner wall of the outer casing, and a hook is fixedly connected to the outer wall of the outer casing.

[0011] Furthermore, one end of the guide pipe is fixedly connected to the inner wall of the oil drum.

[0012] Furthermore, one end of the guide pipe is fixedly connected to the inner wall of the filling material barrel, and the outer wall of the auger is located inside the filling material barrel.

[0013] Furthermore, the outer wall of the elastic sheet is attached to the inner wall of the groove, and two elastic sheets are symmetrically arranged.

[0014] This utility model has the following beneficial effects: In this invention, the heat transfer oil in the oil tank is heated by a heating platform. After heating, the heat transfer oil enters the hydraulic pump through the first guide pipe and is then transported to the second guide pipe to heat the filling material tank. At the same time, the motor drives the auger to stir the filling material, ensuring that it is heated evenly. This solves the problem that traditional equipment is difficult to heat the filling material evenly, which can easily lead to the filling material becoming coking and deformed when the temperature is too high or its fluidity deteriorates when the temperature is too low. This invention achieves the goal of ensuring the stability of the filling material and improving the effect of sealing road cracks.

[0015] In this invention, by rotating the rotating rod, the pin is driven to rotate, causing the groove to disengage from the elastic sheet and releasing the elastic sheet from locking the groove. Then, the pin is pulled out from flange one and flange two to release the locking of both, causing the nozzle to disengage from the filling gun. This allows for flexible replacement of nozzles of different diameters according to construction needs, reducing equipment downtime and achieving the effect of improving the efficiency of road crack sealing operations.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-4 This utility model provides an embodiment of a road crack sealing material extruder, including a shell 1 that protects the internal components. A base plate 5 is fixedly connected to the lower surface of the shell 1, providing a stable mounting foundation for the entire device and bearing the weight of each component. An mounting plate 8 is fixedly connected to the upper surface of the base plate 5, which is used to centrally mount core working components such as the sealing material tank 14 and the conveying pump 17, making the layout of each component neat and convenient for maintenance and repair. The sealing material tank 14 is fixedly connected to the upper surface of the mounting plate 8, which stores the material required for road crack sealing. The conveying pump is fixedly connected to the upper surface of the mounting plate 8. 17. The conveying pump 17 provides power for the material flow. The input end of the conveying pump 17 is fixedly connected to the guide pipe 3 18, which is used to connect the conveying pump 17 and the filling material tank 14. The output end of the conveying pump 17 is fixedly connected to the guide pipe 4 19, and one end of the guide pipe 4 19 is fixedly connected to the filling gun 20. The guide pipe 4 19 is used to connect the conveying pump 17 and the filling gun 20, guiding the filling material pressurized by the conveying pump 17 to the filling gun 20. The filling gun 20 can accurately aim at the road surface crack and inject the filling material into the crack to achieve the sealing and filling of the crack. The upper surface of the mounting plate 8 is provided with a heating component, and one end of the filling gun 20 is provided with a connecting component. The heating assembly includes a heating platform 9, the lower surface of which is set on the upper surface of a mounting plate 8. An oil tank 10 is mounted on the upper surface of the heating platform 9. The heating platform 9 generates heat and transfers it to the oil tank 10. The oil tank 10 stores heat transfer oil and other heat transfer media, and can evenly absorb the heat transferred from the heating platform 9. A guide pipe 11 is fixedly connected to the inner wall of the oil tank 10. A hydraulic pump 12 is mounted above the mounting plate 8. The guide pipe 11 connects the oil tank 10 and the hydraulic pump 12, allowing the heated heat transfer media in the oil tank 10 to enter the hydraulic pump 12. The input end of the hydraulic pump 12 is fixedly connected to one end of the guide pipe 11, and the output end of the hydraulic pump 12 is fixedly connected to one end of the guide pipe 13. 2 provides power for the circulation of the heat transfer medium. The heat transfer medium heated in the oil drum 10 can be pressurized and transported to the second guide pipe 13. At the same time, the heat transfer medium after heat dissipation is drawn back to the oil drum 10, realizing the recycling of the heat transfer medium. The outer wall of the potting material barrel 14 is attached with the second guide pipe 13. The second guide pipe 13 transfers the heat of the internal heat transfer medium to the potting material barrel 14, realizing the heating and heat preservation of the potting material in the barrel. The upper surface of the potting material barrel 14 is equipped with a motor 15. The output end of the motor 15 is fixedly connected to an auger 16. When the auger 16 rotates in the potting material barrel 14, it can stir the potting material in the barrel, so that the material is heated evenly and avoids uneven viscosity of the material due to local temperature differences.

[0020] Specifically, the heat transfer oil in the oil tank 10 is heated by the heating platform 9, and the heated heat transfer oil is pumped by the hydraulic pump 12 and delivered to the guide pipe 13. The guide pipe 13 heats the potting material in the potting material tank 14 evenly through its annular structure. The motor 15 drives the auger 16 to rotate and stir the potting material inside the potting material tank 14, so that it is heated more evenly.

[0021] Reference Figures 1-6 The connecting assembly includes flange 22, whose inner wall is fixedly connected to one end of the filling gun 20. Flange 28 is fitted to the outer wall of flange 22, and nozzle 21 is fixedly connected to the inner wall of flange 28. Flange 28, by fitting with flange 22, enables the nozzle 21 to connect with the filling gun 20, ensuring that material can smoothly enter the nozzle 21 from the filling gun 20. Pins 24 are slidably connected to the inner walls of flanges 22 and 28, and are inserted into flanges 22 and 28. The corresponding holes can lock the two together to prevent relative displacement after docking and ensure the stability of the connection. One end of the pin 24 is fixedly connected to the rotating rod 23, which is easy for the operator to hold and facilitates the insertion and removal of the pin 24. The other end of the pin 24 is provided with a groove 26, which provides a locking position for the elastic piece 25 so that the elastic piece 25 can be embedded therein. The outer wall of the flange 28 is fixedly connected to the elastic piece 25. The elastic piece 25 uses its own elasticity to embed into the groove 26 to limit the pin 24.

[0022] Specifically, when it is necessary to replace the nozzle 21 with a corresponding diameter, the operator only needs to hold the rotating rod 23 and rotate it to drive the pin 24 to rotate synchronously. This causes the groove 26, which was originally tightly fitted with the elastic plate 25, to gradually deviate from its original position, thereby disengaging from the elastic plate 25 and releasing the locking of the elastic plate 25 to the groove 26. The pin 24 can then be pulled out from the corresponding hole of flange 1 22 and flange 28, thereby replacing the nozzle 21.

[0023] Reference Figures 1-6 The base plate 5 has a front wheel 3 and a rear wheel 4 on its outer wall. The rear wheel 4 works with the front wheel 3 to move the equipment as a whole. A push rod 6 is fixedly connected to the upper surface of the base plate 5. The push rod 6 is easy for the operator to hold and push the equipment. By pushing the push rod 6, the movement path of the equipment can be easily controlled to adapt to the position adjustment needs during road operations. A control console 7 is fixedly connected to the inner wall of the push rod 6. The control console 7 integrates the equipment's control buttons, display screen, and other components. The operator can start and stop the equipment and adjust the heating temperature through the control console 7. A heat dissipation plate 2 is fixedly connected to the inner wall of the outer shell 1. The heat dissipation plate 2 can dissipate excess heat from the inside of the outer shell 1. A hook 27 is fixedly connected to the outer wall of the outer shell 1. The hook 27 can be used to hang the filling gun 20, tools and other items for easy access during operation. One end of the guide pipe 2 13 is fixedly connected to the inner wall of the oil drum 10. One end of the guide pipe 3 18 is fixedly connected to the inner wall of the filling material barrel 14. The outer wall of the auger 16 is set inside the filling material barrel 14. The outer wall of the elastic sheet 25 is attached to the inner wall of the groove 26. Two elastic sheets 25 are symmetrically arranged.

[0024] Working principle: When a road crack sealing material extruder is needed, the heating platform 9 heats the heat transfer oil in the oil tank 10. The heated heat transfer oil enters the hydraulic pump 12 through the guide pipe 11. The hydraulic pump 12 delivers the heat transfer oil to the guide pipe 2 13 attached to the outer wall of the sealing material tank 14, so as to achieve uniform heating of the sealing material in the sealing material tank 14. The cooled heat transfer oil is delivered back to the oil tank 10 through the guide pipe 2 13. The motor 15 is started, and its output end drives the auger 16 to rotate, which stirs the heated sealing material in the sealing material tank 14, so that the sealing material is heated more evenly. The delivery pump 17 draws the sealing material from the sealing material tank 14 through the guide pipe 3 18 at the input end, and then delivers the material to the filling gun 20 through the guide pipe 4 19 at the output end, and extrudes it into the road crack through the nozzle 21. Furthermore, when it is necessary to replace the nozzle 21 with a different diameter, the operator rotates the rotating rod 23, which drives the pin 24 to rotate, causing the groove 26 to disengage from the elastic plate 25. This releases the locking of the elastic plate 25 onto the groove 26, allowing the pin 24 to be pulled out from the flange 1 22 and flange 28, thus releasing the locking of the flange 1 22 and flange 28. This allows the nozzle 21 to disengage from the filling gun 20, enabling a quick replacement of the nozzle 21.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
