[0035] Working principle:

[0036] When in use, concrete raw materials are added to the storage barrel 3 through the filling port 16, and then the motor 401 is turned on. At this time, the stirring rod 403 can be driven to rotate with the cooperation of the rotating shaft 402, and then the concrete can be mixed under the action of the stirring rod 403. After the concrete is mixed, the handrail 9 can be pushed to transfer the device to the potholes on the road with the cooperation of the universal wheel 2, and then the first electric telescopic rod 501 is started to retract. At this time, the first mobile frame 503 can be driven to slide in the bottom plate 1 with the cooperation of the connecting block 502. 3 moves downward, which will drive the slide bar 506 to slide in the slide hole 505 of the fixed plate 504, thereby driving the sealing plate 17 to open, so that the concrete in the storage barrel 3 can fall from the drop opening 19 to the potholes on the road. As the first mobile frame 503 moves downward, the linkage rod 801, the connecting rod 802 and the mobile plate 803 can drive the positioning rod 702 to move backward, thereby facilitating the positioning rod 702 to disengage from the positioning hole 20 on the second mobile frame 11. After the positioning rod 702 disengages from the positioning hole 20, the second electric telescopic rod 10 contracts and The cooperation of the mobile frame 11 can drive the scraper 14 and the vibration plate 15 to move downward, so that the raised concrete can be flattened under the action of the scraper 14, and at the same time, the bubbles inside the concrete can be discharged under the cooperation of the vibration plate 15 and the vibration motor 21, so that the compactness of the concrete can be improved, thereby achieving the purpose of repairing the road, which not only reduces the labor intensity of the workers, but also improves the repair efficiency; when the concrete is discharged, the first electric telescopic rod 501 is started to extend, which is convenient for the positioning rod 702 to reset, and then after the concrete is discharged, the electric telescopic rod 501 is started to extend, so that the positioning rod 702 is reset. After the soil is leveled, the second electric telescopic rod 10 is started to extend, and the second mobile frame 11 can be driven to move upward. When the second mobile frame 11 contacts the positioning rod 702, the positioning rod 702 will be squeezed to slide into the sleeve 701, thereby compressing the spring 703. When the positioning rod 702 reaches the positioning hole 20, the spring 703 facilitates the positioning rod 702 to be inserted into the positioning hole 20, thereby achieving the positioning of the second mobile frame 11, thus preventing the second mobile frame 11 from moving downward, thereby improving the protection of the second electric telescopic rod 10.
