Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this utility model belongs. It should also be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances. The terms used in the description of this utility model in this article are only for the purpose of describing specific embodiments and are not intended to limit this utility model.

[0024] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 . A pavement crack repair device includes a bottom plate 1, moving wheels 2 are arranged at the bottom of the bottom plate 1, a tank body 3 is arranged at the top of the bottom plate 1, a push rod 4 is fixedly connected to one side of the bottom plate 1, a sealing cover 5 is arranged at the top of the tank body 3, a motor 6 is arranged at the top of the sealing cover 5, a connecting shaft 7 is fixedly connected to the output end of the motor 6, a cleaning roller 9 is arranged on one side of the connecting shaft 7, and stirring rods are arranged on the outer side of the connecting shaft 7; an installation mechanism 8, the installation mechanism 8 includes a fixing rod 81 fixed on the outer side of the connecting shaft 7, a limiting pin 82 is rotatably connected to the top of the fixing rod 81, a limiting hole 83 is opened in the inner wall of the cleaning roller 9, a positioning rod 84 is arranged on the inner wall of the fixing rod 81, a fixing seat 85 is rotatably connected to the top of the positioning rod 84, a screw rod 86 is fixedly connected to the top of the fixing rod 81, and a nut 87 is threadedly connected to the outer side of the screw rod 86.

[0025] In the specific implementation process, as Figures 1 - 4 shown, the number of the fixing rods 81 and the limiting holes 83 are both set to two.

[0026] A threaded hole 13 is opened in the inner wall of the connecting block 12, and a hand-tightening screw 14 is threadedly connected to the inner wall of the threaded hole 13.

[0027] One side of the tank body 3 is communicated with a connecting pipe 15, a valve 16 is arranged on the outer side of the connecting pipe 15, and one end of the connecting pipe 15 penetrates through the inner wall of the bottom plate 1 and is communicated with a spray head.

[0028] An extrusion roller 17 is arranged at the bottom of the bottom plate 1.

[0029] It should be noted that by setting up the installation mechanism 8, the cleaning roller 9 can be conveniently disassembled and replaced, improving the practicability of the device. A through hole is provided at the top of the tank body 3. Through the setting of the stirring rod, the repair agent can be conveniently stirred to prevent it from solidifying. When in use, the valve 16 is opened to enable the repair agent to enter the connecting pipe 15 and finally spray out from the nozzle, so as to repair the road surface gap. The sprayed repair agent can be compacted by the extrusion roller 17. Then, the cleaning water is poured into the tank body 3, and the motor 6 is started to drive the connecting shaft 7 to drive the installation mechanism 8 to rotate, so that the cleaning roller 9 rotates and the residual repair agent on the inner wall of the tank body 3 is cleaned. When the cleaning roller 9 needs to be replaced, first turn the hand-tightening screw 14 to separate it from the threaded hole 13, then move the sealing cover 5 to separate the connecting block 12, so that the insertion rod 11 is separated from the insertion hole 10, and then the cleaning roller 9 is taken out. Then, the nut 87 is removed from the screw rod 86, so as to release the restriction on the fixed seat 85. Then, the fixed seat 85 is moved to separate the positioning rod 84 from the limit hole 83, so that the old cleaning roller 9 can be disassembled. Then, the limit hole 83 at the bottom of the new cleaning roller 9 is inserted into the limit pin 82, and then the fixed seat 85 is moved to make the positioning rod 84 pass through the fixed rod 81 and insert into the limit hole 83 at the top of the cleaning roller 9, so that the screw rod 86 penetrates through the fixed seat 85. Then, the nut 87 is threadedly connected with the screw rod 86, so as to fix the fixed seat 85 and further fix the cleaning roller 9.

[0030] Reference Figure 1 and Figure 2 As shown in the figure, a connecting rod 18 is slidably connected inside the push rod 4, and a grip is fixedly connected to one side of the connecting rod 18.

[0031] A fixing screw 19 is threadedly connected to the inner wall of the push rod 4, and a threaded hole 20 is provided in the inner wall of the connecting rod 18.

[0032] It should be noted that the user can adjust the height of the connecting rod 18 according to his own height, so as to facilitate the operation. When in use, turn the fixing screw 19 to separate it from the threaded hole 20, then move the connecting rod 18 to drive the grip to move up and down. When the grip is adjusted to a suitable position, then screw the fixing screw 19 into and through the push rod 4 to connect it with the threaded hole 20, so as to fix the connecting rod 18.

[0033] The working principle of a road crack repair device provided by the present utility model is as follows:

[0034] When in use, when the cleaning roller 9 needs to be replaced, remove the nut 87 from the screw 86, so as to release the restriction on the fixed seat 85. Then move the fixed seat 85 to separate the positioning rod 84 from the limit hole 83, so that the old cleaning roller 9 can be disassembled. Then insert the limit hole 83 at the bottom of the new cleaning roller 9 into the limit pin 82, and then move the fixed seat 85 to make the positioning rod 84 pass through the fixed rod 81 and insert it into the limit hole 83 at the top of the cleaning roller 9, so that the screw 86 passes through the fixed seat 85. Then thread the nut 87 onto the screw 86, so as to fix the fixed seat 85, and further fix the cleaning roller 9.

[0035] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. may be used here to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figure is inverted, the device described as "above" or "over" other devices or structures will then be positioned "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both the orientation of "above" and "below". The device can also be positioned in other different ways, such as rotated 90 degrees or in other orientations, and the corresponding explanations are made for the spatial relative descriptions used here.

[0036] In the detailed description above, reference has been made to the accompanying drawings which form a part hereof. In the drawings, like reference numerals typically identify like components, unless the context indicates otherwise. The illustrated embodiments described in the detailed description, the drawings, and the claims are not meant to be limiting. Other embodiments may be used and other changes may be made without departing from the spirit or scope of the subject matter presented herein.

[0037] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
