[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0019] As shown in Figures 1-7 The present application proposes a crack repair and flattening device for highway maintenance. In the present embodiment, the material box 12, the material conveying member 14 and the pressing member 15 are all installed on the vehicle frame 1. The vehicle frame 1 is connected to a tractor head that provides power, thereby driving the movement of the vehicle frame 1. The material conveying member 14 and the pressing member 15 are both installed on the working frame 13 and maintained on the same loading component. When adjusting the equipment, the relative positions of the material conveying member 14 and the pressing member 15 are adjusted synchronously. The material conveying member 14 is used to output repair materials to the highway crack area. With the movement of the vehicle frame 1, the repair materials are filled into the highway crack area. The pressing member 15 is used to press the repair materials. The driving member 16 drives the transmission member 17 to move in a reciprocating and inclined manner. The inclined lifting direction of the transmission member 17 is consistent with the advancing direction of the vehicle frame 1. Then, the flattening member 18 presents a backward pressing and brushing of the repair materials. That is, the excess repair materials after each pressing are brushed into the highway crack space in the rear area. This effectively reduces the process of removing excess repair materials, avoids the existence of gaps between each pressing point that are missed by the unfilled materials, effectively reduces the work amount of the workers and improves the work quality.
[0020] When working, the driving motor 47 is the power end, which drives the transmission disc 33 through the power input shaft 48. The transmission disc 33 is the driving component, and the driven disc 35 is the driven component. The flattening piece 18 moves with the driven disc 35. The transmission disc 33 is limited in the positioning frame 32, which is a circular ring structure, forming an outer ring limiting track for the transmission disc 33, thereby ensuring the stability of the rotation of the transmission disc 33. The connecting slider 45 is used to connect the transmission disc 33 and the driven disc 35. The outer rim 34 is arranged on the periphery of the driven disc 35 and is installed in an outer clamping manner, that is, the outer rim 34 itself does not rotate with the driven disc 35, so that the flattening piece 18 always has a tendency to be vertically downward. The rotation of the transmission disc 33 drives the driven disc 35 to move. The connecting slider 45 is arranged on the side of the center of the disc surface of the transmission disc 33, thereby achieving the effect of eccentric motion. The driven disc 35 takes the connecting slider 45 as the rotation fulcrum. At the same time, the connecting slider 45 is installed in the connecting track 42, thereby being affected by gravity. When the driven disc 35 rotates to the upper edge position, that is, the center height of the disc of the driven disc 35 is higher than the horizontal position of the connecting slider 45, the driven disc 35 will slide downward along the track of the connecting track 42. Therefore, for the outer rim 34 and the flattening piece 18, an inclined arc-shaped motion track is formed, and the arc-shaped motion track is lifted towards the movement direction of the vehicle frame 1. After the repair material is output, it will be accumulated in the highway crack. When working, the flattening piece 18 will first be inclined and lifted, move to the upper edge of the accumulated material, and then be inclined and pressed towards the rear to press the repair material. In actual work, the flattening piece 18 also has the effect of brushing the material to the rear when pressing the material, that is, the excess material after each pressing is brushed to the rear area of the highway crack space. The existing repair material is mainly asphalt or other adhesive material. When this kind of material is transported, it must be a pile of falling. The above structure of the embodiment can effectively avoid the problem of repair gap between each pile of material and improve the overall repair quality. In one case of the embodiment, for the flattening piece 18, the embodiment is designed as follows: please refer to Figure 5The flattening piece 18 comprises an upper pressing rod 53 installed on the supporting block 36, a positioning sleeve 52 installed on the rod end of the pressing rod 53, a fixing pin 51 installed on the positioning sleeve 52, and a pressing plate 55 installed on the fixing pin 51. The pressing rod 53 is insertedly installed in the positioning sleeve 52 in a movable manner. A supporting spring 54 is wound on the pressing rod 53 and supported between the positioning sleeve 52 and the supporting block 36. The pressing plate 55 is used for pressing the repairing material, and the pressing rod 53 is used for supporting the pressing plate 55. In the embodiment, the pressing rod 53 and the pressing plate 55 are movably installed in a small range, and are supported between the positioning sleeve 52 and the supporting block 36 by the supporting spring 54. The flattening piece 18 moves along an arc-shaped track in an inclined manner, so as to adaptively move to the upper edge of each pile of material and then press and brush the material in a backward and inclined manner. The above is the working process of the whole application, and the above steps can be repeated next time.
