It should be noted that when filling and repairing road cracks, the internal material of the storage tank 5 is continuously conveyed to the inside of the rectangular frame 8 by the feeder 6, and at the same time, the hand The hand push frame 3 is pushed to enable the rectangular frame 8 to move along the crack. Since the rectangular frame 8 is in contact with the ground, the material transported to the inside of the rectangular frame 8 will continuously enter the crack to fill it while the rectangular frame 8 is moving, and the rectangular frame 8 will spread the material to the road surface while moving. To avoid material waste, the staff can adjust the distance between the two movable plates 9 according to the width of the crack. If the width of the crack is small, the distance between the two movable plates 9 will be shortened; if the width of the crack is large, the distance between the two movable plates 9 will be increased. When the feeder 6 transports the material to the inside of the rectangular frame 8, the material is always injected into the middle of the two movable plates 9, thereby avoiding the internal width of the rectangular frame 8 being large, causing unnecessary waste when filling the material. The two movable plates 9 limit the width of the material being spread, so that the material is gathered in the crack and effectively utilized.

[0023] like Figures 1 to 3 As shown, the driving mechanism 10 includes a servo motor 101, a rectangular groove 102 is provided on the inner wall of the rectangular frame 8, a rotatable bidirectional thread 103 is movably installed inside the rectangular groove 102, a servo motor 101 for driving the bidirectional thread 103 to rotate is fixedly installed on the side of the rectangular frame 8 away from the bottom plate 1, sliders 104 are respectively threadedly connected at both ends of the bidirectional thread 103, and two movable plates 9 are respectively fixedly connected to the two sliders 104. It should be noted that when the servo motor 101 is started, it can drive the bidirectional thread 103 to reciprocate at a preset angle and speed, so that the two sliders 104 are close to or away from each other, and each slider 104 drives the movable plate 9 connected to it to move synchronously when moving, so as to achieve the effect of the two movable plates 9 approaching or moving away from each other.

[0024] like Figure 2 , Figure 3As shown, a limit block 11 is provided on one side wall of the rectangular frame 8 away from the rectangular groove 102, and a limit groove 12 is fixedly installed at one end of each movable plate 9 close to the limit block 11, and each limit groove 12 is movably installed inside the limit block 11. It should be noted that when each movable plate 9 moves, it drives the limit groove 12 connected to it to slide inside the limit block 11, and the limit groove 12 and the limit block 11 are mainly used to ensure the stable balance performance of the movable plate 9.

[0025] like Figure 2 , Figure 3 As shown, grooves 13 are provided on the sides of the two movable plates 9 that are close to each other, and the two grooves 13 are staggered up and down. Protective rods 14 are fixedly installed on the sides of the two movable plates 9 that are close to each other, and the two protective rods 14 are staggered up and down. Square holes 15 are provided on the two side walls of the rectangular frame 8, and the two square holes 15 are staggered up and down. The two protective rods 14 respectively penetrate the grooves 13 and the square holes 15 on the same horizontal line.

The internal hollow area of ​​each trapezoidal groove 16 passes through the end of the corresponding movable plate 9 close to the limit block 11, and a trapezoidal rod 17 is movably installed inside each trapezoidal groove 16 (each trapezoidal rod 17 in the present technical solution is interference-connected inside the corresponding trapezoidal groove 16), and an extension plate 18 is fixedly installed on the top of each trapezoidal rod 17. It should be noted that if the discharge speed of the feeder 6 is faster, the two trapezoidal rods 17 can be movably installed inside the two trapezoidal grooves 16 respectively, so as to increase the capacity between the two movable plates 9. When there is no need to use two extension plates 18 to increase the capacity, the two trapezoidal rods 17 can be pulled out from the two trapezoidal grooves 16 respectively.

[0027] like Figure 3 As shown, the extension plate 18 is a right-angled triangular plate structure, and the inclined surfaces of the two extension plates 18 are the sides where the two extension plates 18 are close to each other. It should be noted that the capacity between the two extension plates 18 can be further increased.

[0028] In summary:

[0029] When filling and repairing road cracks, the internal material of the storage tank 5 is continuously conveyed to the inside of the rectangular frame 8 by the feeder 6, and at the same time, the hand-held push frame 3 is pushed to enable the rectangular frame 8 to move along the crack. Since the rectangular frame 8 is in contact with the ground, the material conveyed to the inside of the rectangular frame 8 while the rectangular frame 8 is moving will continuously enter the crack to fill it, and the rectangular frame 8 will spread the material on the road surface while moving. To avoid material waste, the staff can adjust the distance between the two movable plates 9 according to the width of the crack. If the width of the crack is small, the distance between the two movable plates 9 is shortened; if the width of the crack is large, the distance between the two movable plates 9 is increased. When the feeder 6 conveys the material to the inside of the rectangular frame 8, the material is always injected into the middle of the two movable plates 9, thereby avoiding the internal width of the rectangular frame 8 being large, causing unnecessary waste when filling the material. The two movable plates 9 limit the width of the material being spread, so that the material is gathered in the crack and effectively utilized.
