[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 A road crack repair device includes a mobile frame 1, a support frame 2 fixedly mounted on the top of the mobile frame 1, a material container 3 fixedly mounted in the middle of the support frame 2, a motor 4 fixedly mounted on the top of the material container 3, a stirring rod 9 fixedly mounted on the output shaft of the motor 4, a scraper 10 fixedly mounted on the outer wall of the stirring rod 9, a hopper 11 provided on the inner wall of the material container 3, a pull rod 7 penetrating through the outer wall of the material container 3, a sleeve 8 communicating with the inside of the hopper 11, a slot 22 opened on the outer wall of the sleeve 8, a baffle 18 tightly fitted to the inner wall of the slot 22, and two outer sides of the baffle 18... All walls are fixedly equipped with sliders 17, and a crossbar 15 is provided in the middle of sliders 17. A return spring 16 is abutted against the outer wall of sliders 17. A straight rod 19 is fixedly equipped on the inner wall of sleeve 8. A return spring 20 is sleeved on the outer wall of straight rod 19. The bottom end of return spring 20 abuts against telescopic tube 12. A sealing ring 14 is provided on the outer wall of telescopic tube 12. A sealing ring 21 is fixedly sleeved on the bottom of the inner wall of sleeve 8. An air pump 5 is fixedly equipped on the top of moving frame 1. An air supply pipe 6 is fixedly sleeved on the output port of air pump 5. A vibration motor 13 is provided on the bottom of the inner wall of material cylinder 3.

[0022] In the above structure, the mobile frame 1, support frame 2, material container 3, motor 4, stirring rod 9, scraper 10, hopper 11, and vibration motor 13 are configured so that during operation, after the user puts the repair agent into the material container 3, the stirring rod 9 and scraper 10 can stir and scrape the repair agent in the hopper 11 through the operation of the motor 4, thereby preventing the repair agent from solidifying and improving the smoothness of the repair agent when discharged. This avoids the repair agent from condensing into lumps and causing blockages. At the same time, the operation of the vibration motor 13 assists the stirring rod 9 and scraper 10 to ensure the storage and stirring effect of the repair agent.

[0023] In a preferred embodiment: the output shaft of the vibration motor 13 is fixedly assembled with the outer wall of the hopper 11, the outer wall of the hopper 11 is movably connected with the inner wall of the sleeve 8, the inner wall of the hopper 11 is in contact with the outer wall of the scraper 10, and the outer wall of the material container 3 is penetrated by a material injection pipe.

[0024] In the above structure, the hopper 11, the vibration motor 13, and the sleeve 8 are configured so that when the vibration motor 13 is in operation, it will drive the hopper 11 to vibrate, thereby providing vibration force to the repair agent in the hopper 11, thus maintaining the fluidity of the repair agent, and improving the practicality of the device and the discharge effect of the repair agent.

[0025] In a preferred embodiment: a circular groove is provided at the top of the telescopic tube 12, and the inner wall of the circular groove is fixedly assembled with the outer wall of the sealing ring 14, and the inner wall of the sealing ring 14 is tightly fitted with the outer wall of the straight rod 19.

[0026] In the above structure, through the set circular groove and sealing ring 14 structure, when the user needs to repair cracks of different depths, the user can use the air pump 5 to pressurize the interlayer between the sleeve 8 and the telescopic pipe 12 through the air supply pipe 6, or use the solenoid valve to release pressure, thereby achieving the effect of adjusting the total length of the sleeve 8 and the telescopic pipe 12, thus improving the repair effect and repair range of the device.

[0027] In a preferred embodiment: the middle part of the material container 3 is provided with an installation groove, and the inner wall of the installation groove is slidably connected to the outer wall of the baffle 18, and the outer wall of the slider 17 is slidably connected to the outer wall of the crossbar 15.

[0028] In the above structure, through the installation groove and baffle 18 structure, when the user needs to discharge the repair agent, he can pull the lever 7 to move the baffle 18 toward the reset spring 16, thereby connecting the sleeve 8 with the telescopic tube 12, thus ensuring the normal use of the device.

[0029] In a preferred embodiment: the outer wall of the material container 3 is provided with a square groove, and the inner wall of the square groove is slidably connected to the outer wall of the pull rod 7, and the outer wall of the baffle 18 is fixedly assembled with the outer wall of the pull rod 7.

[0030] In the above structure, with the square groove and pull rod 7, the user only needs to pull the pull rod 7 to perform the repair work, without the user having to perform any other manual operations on the device, thereby reducing the user's workload and improving the automation of the device.

[0031] In a preferred embodiment: the outer wall of the telescopic tube 12 is slidably connected to the inner wall of the sleeve 8, air is filled between the top of the telescopic tube 12 and the bottom of the inner wall of the sleeve 8, a pressure relief pipe passes through the bottom of the sleeve 8, and a solenoid valve is provided on the inner wall of the pressure relief pipe.

[0032] In the above structure, by using the pressure relief pipe and solenoid valve, when the telescopic pipe 12 needs to be lowered to repair deeper cracks, the opening of the solenoid valve allows the air between the telescopic pipe 12 and the sleeve 8 to be discharged to the outside of the sleeve 8 through the pressure relief pipe, thereby reducing the air pressure between the sleeve 8 and the telescopic pipe 12. The elasticity of the return spring 20 pushes the telescopic pipe 12 downward, thereby achieving the effect of quickly adjusting the length of the sleeve 8 and the telescopic pipe 12.

[0033] Working principle: After assembling the device, the user can add repair agent to the container 3 through the injection pipe. At this time, the motor 4 starts to operate, causing the stirring rod 9 and scraper 10 to stir and scrape the repair agent respectively, avoiding the solidification and adhesion of the repair agent during storage. This improves the fluidity of the repair agent when the user releases it, thereby improving the practicality of the device. When repairing cracks of different depths, the user can increase the air pressure between the sleeve 8 and the telescopic tube 12 through the operation of the air pump 5. This causes the telescopic tube 12 to gradually compress the return spring 20, shortening the total length of the telescopic tube 12 and the sleeve 8, thus repairing shallower cracks. Conversely, the pressure relief pipe is used to release pressure, achieving the effect of repairing deeper cracks. This improves the repair effect and repair range of the device.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
