[0025] In order to achieve the function of mixing raw materials, the mixing device 2 further includes: a cross-shaped connecting protrusion 213, which is fixedly installed at the end of the first connecting shaft 212 away from the first motor 211; a protruding shaft 201, which is fixedly installed on the center of the bottom wall of the mixing tank 200; a groove 203 and a cross groove 204, which are respectively opened at both ends of the rotating shaft 202, the outer contour of the groove 203 is adapted to the outer contour of the protruding shaft 201, and the outer contour of the cross groove 204 is adapted to the cross-shaped connecting protrusion 213.

[0026] To ensure that electrical components are powered and work together, the electrical power supply control device 6 includes: a main controller 600, which consists of an industrial control panel and a microprocessor controller, and is fixedly installed on the upper surface of the mounting platform 1 at the end away from the monitoring camera 11; a battery 601, a circuit breaker 602, a relay 603, and an inverter 604, all fixedly installed on the upper surface of the mounting platform 1; the output terminal of the battery 601 is electrically connected to the input terminals of the main controller 600 and the inverter 604 respectively; the output terminal of the inverter 604 is electrically connected to the input terminal of the relay 603; the output terminal of the relay 603 is electrically connected to the input terminal of the circuit breaker 602; the output terminal of the circuit breaker 602 is electrically connected to the first motor 211, the second motor 300, the third motor 401, and the blower 500; and the main controller 600 is electrically connected to the pressure sensor 207 and the monitoring camera 11.

[0027] The repair method using a road surface repair device, with the following specific steps: S1. Adding raw materials: Before use, input the mixing ratio on the main control platform, and then add the raw materials into the mixing tank 200. The pressure sensor 207 will sense the weight of the added raw materials, making it easier for workers to control the raw material ratio. S2. Stirring raw materials: After adding the raw materials, install the bucket lid 210 on the mixing bucket 200 and align the cross connecting protrusion 213 with the rotating shaft 202. After installation, start the first motor 211. When the first motor 211 is working, it drives the rotating shaft 202 and the stirring blade 205 to rotate to stir and mix the raw materials. S3. Repair preparation: Start the third motor 401, so that the third lead screw 402 rotates and drives the third slide bar 403 and the long plate 404 to descend until the material box 407 is in contact with the ground and the crack to be repaired is located below the material box 407. At the same time, start the heating coil 303 to preheat the inner cavity of the conveying pipe 302. S4. Crack Filling and Repair: Start the second motor 300 and blower 500. Blower 500 blows out a strong airflow to blow away debris on the ground. The second motor 300 drives the screw 301 to rotate. When the screw 301 rotates, it sends the mixed filler material in the mixing tank 200 into the discharge pipe 400, and then through the discharge pipe 400 into the discharge box 407. At this time, the worker pulls the device to move the pressure sensor 207 along the gap, so that the filler material can fall into the gap.

[0028] Before use, remove the lid 210 and add raw materials to the mixing tank 200 in batches. The pressure sensor 207 can sense the weight of the raw materials on the rubber pad 208, which can assist workers in adding raw materials and provide a reference for the proportion of various raw materials. When the device is in use, the weight sensed by the pressure sensor 207 can help workers judge the remaining amount of material in the mixing tank 200. The pressure sensor 207 will transmit the sensed pressure value to the main controller 600 and display it. After adding the raw materials, install the lid 210 back onto the mixing tank 200. During installation, the cross connecting protrusion 213 needs to be inserted into the cross groove 204. The main controller 600 starts the relay 603 to supply power to the first motor 211 to start the first motor 211. When the first motor 211 is working, it drives the rotating shaft 202 and the stirring blade 205 to rotate. When the stirring blade 205 rotates, it stirs the raw materials to mix them.

[0029] Example 2: like Figures 9-10 As shown, this embodiment of the invention provides an automated road repair device, which is further expanded based on the content of specific embodiment one: To achieve the function of road repair, the spiral heating conveying device 3 includes: a conveying pipe 302, fixedly installed at the bottom of the installation platform 1, with a connecting wall 304 fixedly installed between the conveying pipe 302 and the discharge hole 206, the discharge hole 206 communicating with the inside of the conveying pipe 302 through the connecting wall 304, and a discharge trough 305 opened at the end of the conveying pipe 302 away from the connecting wall 304, with the discharge trough 305 opening downwards; a heating coil 303, spirally fixedly installed inside the inner wall of the conveying pipe 302; a second motor 300, fixedly installed at one end of the conveying pipe 302; and a screw 301, rotatably installed inside the conveying pipe 302, with one end of the screw 301 penetrating through the conveying pipe 302 and fixedly connected to the output end of the second motor 300. The fitting repair device 4 includes: a discharge pipe 400, fixedly installed on the conveying pipe 302. Below 02, one end of the material discharge pipe 400 is fixedly installed inside the material discharge trough 305; a long plate 404 is installed below the material discharge pipe 400, and a sliding pipe 405 is fixedly installed on the material discharge pipe 400, which is slidably installed inside the material discharge pipe 400; a material discharge box 407 is fixedly installed on the lower surface of the long plate 404. The fitting and repair device 4 also includes: a third motor 401, fixedly installed on the lower surface of the installation platform 1, with a third lead screw 402 fixedly installed at the output end of the third motor 401; a third sliding rod 403, fixedly installed on the lower surface of the installation platform 1 away from the third motor 401; and a limiting post 406, fixedly installed on both sides of the upper surface of the third lead screw 402, with the third sliding rod 403 slidably installed inside the limiting post 406, and the third motor 401 threadedly installed inside the limiting post 406.

[0030] While mixing the raw materials, power can be supplied to the heating coil 303 to heat the inner cavity of the conveying pipe 302. The inner wall of the conveying pipe 302 is made of a metal material with good thermal conductivity, and the temperature is controlled by the temperature controller 306. After preheating, the third motor 401 is started by the preset program on the main controller 600, which drives the third lead screw 402 to rotate in the preset direction, thereby driving the third slide bar 403 and the long plate 404 to descend. When the bottom surface of the material box 407 touches the ground, the third motor 401 stops, and the second motor 300 can be started. After the second motor 300 starts, it drives the screw 301 to rotate. When the screw 301 rotates, the default... The rotation direction allows the replenishment material to be conveyed from one end of the second motor 300 to one end of the material drop chute 305. The replenishment material falls through the material drop chute 305 into the material drop pipe 400 and into the material drop box 407. Since the bottom surface of the material drop box 407 is flush with the ground, the worker pulls the device to move it, and the material drop box 407 is always positioned on the repair area during the movement. During the movement, the replenishment material in the material drop box 407 will fall into the gap on the ground below to fill it. During the movement, the monitoring camera 11 will capture the image of the material drop box 407 and the ground area and display the image on the main controller 600 in real time, so that the worker can control the movement of the device and ensure that the material drop box 407 is always positioned on the gap.

[0031] Example 3: like Figure 8 As shown, this embodiment of the invention provides a road repair device, which is further expanded based on the content of specific embodiment two: In order to remove debris from road surface cracks and ensure repair quality, the impurity removal device 5 includes: a blower 500, which is fixedly installed on the upper surface of the installation platform 1; an air duct 501, one end of which is fixedly connected to the air outlet of the blower 500, and the other end of which passes through the installation platform 1 and is suspended below the installation platform 1, with a rounded corner and threads on the rounded corner at the end of the air duct 501 away from the blower 500; a universal joint 503 and a flat-nozzle air outlet duct 502, which are integrally formed, and the flat-nozzle air outlet duct 502 is rotatably installed on the rounded corner end of the air duct 501.

[0032] If there are impurities such as dust and gravel particles in the gap, the blower 500 can be started while filling. The airflow blown by the blower 500 will be directed at the ground crack through the air duct 501 and the flat nozzle air outlet 502. When the mobile device is used for repair, the worker should pull the handle 9 to move the device in a linear direction from the material drop box 407 to the flat nozzle air outlet 502. This ensures that the flat nozzle air outlet 502 blows out the debris from the gap first, and then the material drop box 407 moves to the gap for filling.

[0033] Working principle: Before use, remove the lid 210 and add raw materials to the mixing tank 200 in batches. The pressure sensor 207 can sense the weight of the raw materials on the rubber pad 208, which can assist the worker in adding raw materials and serve as an auxiliary reference for the proportion of various raw materials. When the device is in use, the worker can easily judge the remaining amount of material in the mixing tank 200 based on the weight sensed by the pressure sensor 207. The pressure sensor 207 will transmit the sensed pressure value to the main controller 600 for display. After adding the raw materials, install the lid 210 back onto the mixing tank 200. During installation, the cross-shaped connecting protrusion 213 must be inserted into the cross-shaped groove 204. The main controller 600 is activated. The relay 603 powers the first motor 211 to start it. When the first motor 211 is working, it drives the rotating shaft 202 and the stirring blade 205 to rotate. The stirring blade 205 agitates the raw materials to mix them. Simultaneously, it powers the heating coil 303 to heat the inner cavity of the conveying pipe 302. The inner wall of the conveying pipe 302 is made of a metal material with good thermal conductivity. After preheating, the third motor 401 is started by a preset program on the main controller 600, causing the third lead screw 402 to rotate in a preset direction, which in turn causes the third slide bar 403 and the long plate 404 to descend. When the bottom of the material box 407... When the surface touches the ground, the third motor 401 stops, and the second motor 300 can then be started. The second motor 300 drives the screw 301 to rotate. The default rotation direction of the screw 301 allows the replenishment material to be transported from one end of the second motor 300 to one end of the material discharge chute 305. The replenishment material falls through the material discharge chute 305 into the material discharge pipe 400 and then into the material discharge box 407. Since the bottom of the material discharge box 407 is flush with the ground, the worker pulls the device to move it, ensuring that the material discharge box 407 remains on the repair area. During movement, the replenishment material in the material discharge box 407 will fall into the gaps in the ground below to fill them. The monitoring camera 11 will capture this movement. The image of the material drop box 407 and the ground area is displayed in real time on the main controller 600, which facilitates the worker's control of the device's movement and ensures that the material drop box 407 is always positioned on the gap. If there are impurities such as dust and gravel particles in the gap, the blower 500 can be started while filling. The airflow blown by the blower 500 will be directed at the ground crack through the air duct 501 and the flat nozzle air outlet 502. When moving the device for repair, the worker should pull the handle 9 to move the device in a linear direction from the material drop box 407 to the flat nozzle air outlet 502. This ensures that the flat nozzle air outlet 502 blows out the debris from the gap first, and then the material drop box 407 moves to the gap for filling.

[0034] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
