[0023] 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.
[0024] Please see Figures 1 to 6This utility model provides a technical solution: a municipal road surface repair device, including a road repair vehicle body 1. A mixing mechanism is installed on the top of the road repair vehicle body, and the mixing mechanism includes a mixing tank 2. The mixing tank 2 is fixedly installed on the top of the road repair vehicle body 1. An inlet 21 is provided on the top of the mixing tank 2, and a cover 28 is provided on the top of the inlet 21. When in use, the cover 28 is opened, and repair material (asphalt or concrete) is fed into the mixing tank 2 through the inlet 21. When not in use, the cover 28 is closed to prevent other items from entering the mixing tank 2 and affecting the purity of the repair material. The top of the mixing tank 2 is fixedly installed... Equipped with a first motor 22, the mixing tank 2 has a rotatably connected mixing shaft 23. The output end of the first motor 22 is fixedly connected to one end of the mixing shaft 23. Several mixing blades 24 are fixedly installed on the outside of the mixing shaft 23. By starting the first motor 22, the mixing shaft 23 is driven to rotate, which in turn drives the externally mounted mixing blades 24 to rotate, thus fully mixing the asphalt inside, accelerating the asphalt forming speed, and improving repair efficiency. The mixing tank 2 is equipped with an electric heating mechanism 27, preferably an electric heater, which is placed inside the mixing tank 2. It heats the asphalt by connecting to a power source, and the electric heating mechanism 27 controls the mixing. The asphalt inside the mixing tank 2 is heated, making it less viscous and more fluid, facilitating road repair. A discharge pipe 25 is located at the center of the bottom of the mixing tank 2, passing through the road repair vehicle body 1. A bidirectional lead screw 31 is rotatably mounted inside the road repair vehicle body 1 via bearings, passing through the discharge pipe 25. A second motor 3 is fixedly mounted on one side of the road repair vehicle body 1, with its output end fixedly connected to one end of the bidirectional lead screw 31. Slider blocks 32 are threaded onto the outer sides of the two ends of the bidirectional lead screw 31 with opposite thread directions. The middle section of the bidirectional lead screw 31 is smooth, and its connection point with the discharge pipe 25... A sealing ring is provided, and a connecting plate 33 is fixedly installed at the bottom of the slider 32. Slide grooves 26 are opened on the corresponding two sides of the discharge pipe 25. The connecting plate 33 is slidably connected to the slide grooves 26, and the connecting plate 33 is in contact with the inner wall of the slide groove 26. By starting the second motor 3, the bidirectional lead screw 31 is driven to rotate, causing the sliders 32 on both sides to move in opposite directions. At the same time, the connecting plate 33 installed at the bottom is driven. At this time, the connecting plate 33 no longer seals the discharge pipe 25, so that the asphalt flows out from the discharge pipe 25. When not in use, the two connecting plates 33 are in contact at their closest ends to prevent the asphalt from flowing out from the discharge pipe 25 and avoid unnecessary losses.
[0025] An electric push rod 14 is fixedly installed inside the bottom of the road repair vehicle body 1. A mounting plate 13 is fixedly installed at the bottom of the electric push rod 14, and a water supply pipe 44 and an air supply pipe 12 are installed at the bottom of the mounting plate 13. An air nozzle 11 is installed at the bottom of the air supply pipe 12.
[0026] An air intake box 10 is installed on the side of the road repair vehicle body 1. An air pump 16 is installed inside the air intake box 10. A motor heat pipe 15 is installed inside the air intake box 10 and below the air pump 16. The bottom of the air intake box 10 is fixedly connected to the air supply pipe 12 through a hose.
[0027] A water tank 4 is fixedly installed on the top of the road repair vehicle body 1. A water pump 41 is fixedly installed on the top of the road repair vehicle body 1 and on one side of the water tank 4. The water pump 41's suction end extends into the interior of the water tank 4, and a water outlet hose 42 is sleeved on the water pump 41. The water outlet hose 42 passes through the road repair vehicle body 1, and one end of the water outlet hose 42 is fixedly connected to a water supply pipe 44. Several nozzles 43 are fixedly connected to the bottom of the water supply pipe 44.
[0028] A sweeping mechanism 5 is fixedly installed at the bottom of the road repair vehicle body 1. The sweeping mechanism 5 includes a third motor 51 and an electric push rod 54. The electric push rod 54 is installed inside the road repair vehicle body 1. One end of the electric push rod 54 is connected to the third motor 51. A sweeping disc 52 is fixedly installed at the output end of the third motor 51. A brush 53 is fixedly installed at the bottom of the sweeping disc 52. By activating the electric push rod 54, the sweeping disc 52 can be moved up and down, thereby causing the brush 53 below the sweeping disc 52 to contact the damaged and dented areas of the road surface. Telescopic dust covers for telescopic rods are installed on the electric push rod 54 and the electric push rod 14.
[0029] The third motor 51 is started, driving the sweeping disc 52 to rotate. The rotating brush 53 contacts the ground to sweep it, sweeping the dirt to the outside of the damaged area. At the same time, the water pump 41 draws water from the water tank 4 and sprays the road surface and brush 53 through the nozzle 43 installed at one end of the water hose 42, making it cleaner.
[0030] If asphalt repair material is used, it is not necessary to rinse with water. Alternatively, after rinsing, start the air pump 16 and the motor heat pipe 15. Use the air pump 16 to extract air, and heat the airflow through the motor heat pipe 15. Then, blow the hot airflow onto the repair area through the nozzle 11 below the air pipe 12. Use the hot airflow to dry the repair area and blow away the dust, so that the asphalt can better adhere to the ground, increase its stability, and prevent cracking.
[0031] The bottom of the road repair vehicle body 1 is equipped with a pressing mechanism 6. The pressing mechanism 6 includes a mounting frame 61. The top of the mounting frame 61 is fixedly connected to the bottom of the road repair vehicle body 1. A pressure roller 62 is rotatably connected inside the mounting frame 61. The weight of the pressure roller 62 flattens the asphalt, keeping the road surface flat. The bottom of the road repair vehicle body 1 is equipped with casters 7, and the top of the road repair vehicle body 1 is fixedly equipped with a push handle 8. The combination of the casters 7 and the push handle 8 makes it easy for workers to move the device, making it more labor-saving and improving the practicality of the device.
[0032] In summary, when using this municipal road surface repair device, if the road surface is asphalt, the first step is to manually treat the damaged area, such as removing loose parts and clearing away large pieces of debris.
[0033] Step 2: Move the device to the surface that needs repair using the casters 7 and push handle 8. Activate the electric push rod 54 and the third motor 51. The electric push rod 54 drives the sweeping disc 52 downwards, causing the brush 53 below the sweeping disc 52 to contact the damaged and dented area of the surface where the third motor 51 is located, thus cleaning the surface that needs repair.
[0034] Third, activate the electric push rod 14 to lower the mounting plate 13 and water supply pipe 44. Another worker can stand to the side of the device to observe the position, ensuring the nozzle 43 sprays liquid towards the repair area. Use the nozzle 43 to spray water from the water tank 4 to clean the repair area. During the cleaning process, the equipment can be moved back and forth to improve the rinsing effect.
[0035] Step 4: After cleaning, start the air pump 16 and the motor heat pipe 15. Use the air pump 16 to extract air, and the airflow is heated by the motor heat pipe 15. Then, it is blown onto the repair area through the nozzle 11 below the air supply pipe 12. The hot airflow dries the area, preventing water stains from affecting the asphalt repair. After drying, residual dust in the damaged and dented area can also be blown away. If water easily accumulates in the repaired dent, rinsing is not necessary.
[0036] The first motor 22 is started to drive the mixing blades 24 on the mixing shaft 23 to rotate, which mixes the asphalt inside the mixing tank 2 and speeds up the asphalt forming speed. The electric heating mechanism 27 installed inside the mixing tank 2 heats the asphalt inside, making it less viscous and more fluid, which is convenient for road repair. After mixing, the second motor 3 is started to drive the bidirectional lead screw 31 to rotate, which moves the sliders 32 on both sides in opposite directions, moving the connecting plate 33 away from the discharge pipe 25 and no longer sealing the discharge pipe 25. The mixed asphalt flows out from the discharge pipe 25 to repair the road surface. At the same time, the weight of the pressure roller 62 is used to squeeze it and make it flat, which is convenient for vehicles to drive on later.
[0037] The power supply for the device can be a portable battery, which can be placed on the right side of the upper surface of the road repair vehicle body 1. All electrical components of the device are equipped with external power cords and control switches for turning on and off (not shown in the figure as this is known technology).
