[0027] Example 1

[0028] like Figure 1-4 As shown, a road crack filling device is provided, including a material box 1, to which a handrail 2 is fixedly connected. The handrail 2 can be used as a force point to operate the material box 1 to move. A discharge valve 9 is arranged under the material box 1, and the mortar in the material box 1 can be discharged by opening the discharge valve 9.

[0029] The material box 1 is also provided with a transparent window, through which the remaining amount of mortar inside the material box 1 can be observed from the outside.

[0031] A stirring assembly 3 is provided in the material box 1. The stirring assembly 3 includes a rotating shaft 34. A plurality of stirring blades 33 are fixedly connected to the outside of the rotating shaft 34. The rotating shaft 34 is rotatably connected to two first bearings 35. The first bearings 35 can maintain smooth rotation of the rotating shaft 34. The two first bearings 35 are fixedly installed on the stirring box. The top of the rotating shaft 34 is fixedly connected to the output shaft of the motor 32. The motor 32 drives the rotating shaft 34 to rotate. The rotating shaft 34 can drive the stirring blades 33 to stir the mortar to flow and maintain the activity of the mortar. Both sides of the motor 32 are fixedly connected with fixed frames 31. The motor 32 can be fixed by the fixed frames 31 to maintain the stability of the motor 32. The two fixed frames 31 are installed above the material box 1.

[0032] A stirring assembly 8 is provided below the stirring assembly 3, and the stirring assembly 8 includes a sleeve 81, which is embedded below the rotating shaft 34 and extends from the bottom of the material box 1. A hexagonal column 82 is slidably provided inside the sleeve 81, and the hexagonal column 82 can move up and down in the sleeve 81, so that the upper and lower position heights of the blades 83 can be adjusted to meet the construction requirements of road cracks of different depths.

[0033] Furthermore, the hexagonal column 82 is hexagonal in shape, thereby preventing the sleeve 81 and the hexagonal column 82 from rotating relative to each other, so that the sleeve 81 can smoothly drive the hexagonal column 82 to rotate. A plurality of blades 83 are fixed to the outside of the hexagonal column 82, and the hexagonal column 82 is fixed in the sleeve 81 by bolts. The hexagonal column 82 can be fixed by bolts to prevent the hexagonal column 82 from detaching from the sleeve 81.

[0034] A plurality of moving components 5 and threaded adjustment components 6 are connected to the bottom of the material box 1. The moving component 5 includes an electric push rod 51, which is fixedly installed at the bottom of the material box 1. A moving wheel 52 is fixedly connected to the bottom of the electric push rod 51. The electric push rod 51 retracts to drive the material box 1 down, so that the blade 83 can smoothly extend into the crack of the road. After the electric push rod 51 is extended, the transfer of the material box 1 can be facilitated, and the moving wheel 52 can assist the material box 1 in labor-saving transfer.

[0035] A toothed plate 13 is connected to the top of the threaded adjustment component 6 , and two sides of the toothed plate 13 are respectively meshed with two gears 11 . The gears 11 are hinged to the bottom of the material box 1 through pins 12 , and the bottom ends of the two pins 12 are connected to adjustable plates 7 .

[0036] In this embodiment: the electric push rod 51 is retracted to drive the material to move downward, so that the blade 83 enters the road crack, and then the discharge valve 9 is opened. At this time, the material box 1 is pushed by the handrail 2 to move along the crack direction, so that the mortar can be discharged into the crack in turn, and the adjustable plate 7 can be scraped and leveled to facilitate the filling of the crack, and the motor 32 drives the rotating shaft 34 to rotate, so that the hexagonal column 82 drives the blade 83 to rotate, and the blade 83 stirs the mortar in the crack, so that the mortar can fully fill the road crack, preventing the occurrence of filling gaps, thereby improving the construction quality and efficiency.

[0037] Example 2

[0038] On the basis of Example 1, Figure 5-6As shown, the thread adjustment assembly 6 includes a fixing plate 65, which is fixed below the material box 1. A second bearing 62 is installed below the fixing plate 65. The screw 63 can be supported by the second bearing 62, so that the screw 63 can also rotate smoothly by relying on the second bearing 62. The screw 63 is rotatably connected in the second bearing 62. One end of the screw 63 is fixedly connected to a handle 61. The handle 61 is used as a force application point to control the rotation of the screw 63. The screw 63 is threadedly connected to a threaded barrel 64. The screw 63 is transmitted with the threaded barrel 64, so that the threaded barrel 64 can drive the tooth plate 13 to move horizontally. The upper part of the threaded barrel 64 is fixedly connected with the tooth plate 13. A dovetail groove 14 is provided on the upper part of the tooth plate 13. The tooth plate 13 can slide smoothly along the dovetail bar 10 through the dovetail groove 14, so that the tooth plate 13 can be smoothly transmitted with the gear 11, so that the angle between the two side plates 71 can be adjusted. The tooth plate 13 is slidably connected to the dovetail bar 10 through the dovetail groove 14, and the dovetail bar 10 is fixedly connected to the bottom of the material box 1.

[0039] The adjustable plate 7 includes two side plates 71, and the two side plates 71 are respectively fixed to the bottom ends of the two pin shafts 12, and an elastic steel sheet 72 is fixedly connected between the two side plates 71. The side plates 71 can block the two sides of the crack to prevent the mortar from spreading outward, and the elastic blocking sheet can also push the mortar into the crack smoothly. Secondly, the elastic steel sheet 72 can move elastically, so that the side plates 71 can be adjusted smoothly.

[0040] In this embodiment: the screw rod 63 can be rotated by the handle 61, and the transmission of the screw rod 63 and the threaded barrel 64 can drive the tooth plate 13 to move, so that the tooth plate 13 and the gear 11 are transmitted, and the pin shaft 12 can drive the two side plates 71 to adjust the angle, so that it can be adjusted according to the cracks to meet the actual road construction needs.

[0041] The working principle of the utility model is as follows: when constructing road cracks, the electric push rod 51 retracts to lower the height of the material box 1, so that the blade 83 extends into the road crack, and the handle 61 is turned to drive the screw 63 to rotate, so that the screw 63 and the threaded barrel 64 drive the toothed plate 13 and the gear 11 to drive, so that the pin shaft 12 drives the side plate 71 to adjust the angle, so that the distance between the two side plates 71 matches the crack width, and then the discharge valve 9 can be opened, and the material box 1 is pushed along the crack through the handrail 2, so that the mortar can be discharged into the crack in turn under the limit of the two side plates 71, and the motor 32 drives the rotating shaft 34 to rotate, and the rotating shaft 34 drives the sleeve 81 and the hexagonal column 82 to rotate, so that the blade 83 stirs the mortar to fill the gap of the crack, and at the same time, as the road crack filling equipment moves, the scraper 72 scrapes the mortar flat, so that the mortar is pressed into the crack.

[0042] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
