[0028] An installation chamber 92 is provided on the left side of the interior of the extension plate 91, a first limiting groove 93 is provided on the left side wall of the installation chamber 92, a connecting chamber 94 is provided on the right side of the interior of the extension plate 91, second limiting grooves 95 are provided on the upper and lower sides of the connecting chamber 94, handles 96 are fixedly installed on the right sides of the front and rear ends of the extension plate 91, the installation chamber 92 is connected up and down, the connecting chamber 94 is connected left and right, the installation chamber 92 is connected to the connecting chamber 94, a sliding block 102 is fixedly installed on the left side of the movable plate 101, a second sleeve hole 104 is provided on the right side of the movable plate 101, a connecting plate 105 is fixedly installed on the right side of the movable plate 101, a limiting plate 106 is fixedly installed on the interior of the connecting plate 105, a control plate 107 is fixedly installed on the right side of the connecting plate 105, and the second sleeve hole 104 is movable inside A squeezing plate 108 is movably installed, and a pull ring 109 is movably installed inside the control plate 107. A connecting rod 110 is fixedly connected between the squeezing plate 108 and the pull ring 109. The connecting rod 110 is located inside the movable plate 101, the connecting plate 105 and the control plate 107, and the connecting rod 110 passes through the limiting plate 106. The surface of the connecting rod 110 is located between the squeezing plate 108 and the limiting plate 106 and is sleeved with a spring 111. The sliding block 102 is consistent with the first limiting groove 93, and the upper and lower ends of the limiting plate 106 extend out of the surface of the connecting plate 105. The limiting plate 106 is consistent with the second limiting groove 95. The extrusion plate 108 inserted into the second sleeve hole 104 can extrude the discharging pipe 8 and close it. The discharging port of the discharging pipe 8 extends to the bottom of the movable plate 101 and is located on the right side of the scraper plate 4.

[0029] By adopting the above technical solution, when in use, the asphalt storage box 7 is filled with asphalt, a motor is arranged on the top of the asphalt storage box 7 and a stirring device is arranged inside the asphalt storage box 7. The asphalt in the asphalt storage box 7 is stirred by the motor to avoid solidification due to long-term static state. The device can be pushed by the handles 96 installed at the front and rear ends of the extension plate 91, and the device is moved above the cracks in the road surface and the discharge port of the discharge pipe 8 is aligned with the cracks below. When adjusting the position of the discharge port of the discharge pipe 8, the vehicle board 1 does not need to be moved directly. The staff can hold the control panel 107 with one hand and move it through the control panel 107. The movable plate 101 in the installation chamber 92 can be moved to both sides in the installation chamber 92. The discharge pipe 8 is fixed in the movable plate 101 through the second sleeve hole 104 and the extrusion plate 108. Therefore, the position of the discharge port at the bottom of the discharge pipe 8 can be moved by moving the control panel 107. When the asphalt is injected into the cracks on the ground, the vehicle plate 1 is in the forward state. The staff pushes the device forward through the handle 96. When moving forward, the staff needs to pay attention to the direction of the cracks on the ground. In order to facilitate the control of the direction of the discharge port of the discharge pipe 8, one hand can be used to push the device forward through the handle 96, and the other hand can be used to hold the control panel 107 to control the discharge pipe 8;

[0030] An extrusion plate 108 is provided in the second sleeve hole 104. In a normal state, the extrusion plate 108 is in a state of squeezing the discharge pipe 8 through the spring 111, and the discharge pipe 8 is in a closed state. The asphalt cannot be discharged through the discharge pipe 8. The other end of the extrusion plate 108 is connected to a pull ring 109 through a connecting rod 110, and the pull ring 109 is provided in the control panel 107. When the staff holds the control panel 107, they can pull the pull ring 109 with their fingers. When the pull ring 109 is pulled, the extrusion plate 108 will move, so that the extrusion plate 108 will no longer squeeze the discharge pipe 8. At this time, the asphalt can be discharged downward through the extrusion plate 108. This structural design is convenient for the staff to control the asphalt discharge in time, and further improves the convenience of road maintenance work.

[0031] Specifically, Figures 1 to 3 As shown, an air duct 6 is fixedly installed on the right side of the bellows 5, and a first socket hole 103 is opened on the left side inside the movable plate 101. The air duct 6 is inserted into the first socket hole 103. The air outlet of the air duct 6 extends to the bottom of the movable plate 101 and is located on the left side of the scraper plate 4. The air duct 6 and the discharge pipe 8 both move with the movement of the movable plate 101.

[0032] By adopting the above technical scheme, a bellows 5 is installed on the top of the vehicle plate 1, and the air duct 6 connected to the right side of the bellows 5 is also fixed on the movable plate 101 through the first socket hole 103, so that the air duct 6 and the discharge pipe 8 can move at the same time. Through the arrangement of the bellows 5 and the air duct 6, dust, stones and other objects in the cracks of the road surface can be blown out, which can improve the effect of subsequent road maintenance. The air duct 6 and the discharge pipe 8 are bound together, and the air duct 6 is also controlled when the direction of the discharge pipe 8 is controlled, so that the air outlet of the air duct 6 is always facing the cracks in the road surface below, which can improve the cleaning effect of the cracks. At the same time, a dust scraper 4 is installed between the two groups of legs 2 on the right side of the bottom of the vehicle plate 1. The dust scraper 4 can scrape away the dust and stones blown out of the cracks, further improving the cleaning effect of the cracks.

[0033] Working principle: When working, first inject asphalt into the asphalt storage box 7, the staff can push the device to move through the handle 96, move the device to the top of the ground crack, and adjust the discharge pipe 8 to face the ground crack below through the cooperation of the limiting component 9 and the moving component 10 to start working. When injecting asphalt into the crack, the staff can push the device through the handle 96 with one hand, grab the control panel 107 with one hand and buckle the finger into the pull ring 109, the finger buckles the pull ring 109, and the pull ring 109 drives the extrusion plate 108 to retract, and the asphalt can be discharged through the discharge pipe 8 When the pull ring 109 is released, the extrusion plate 108 will automatically reset due to the existence of the spring 111 to close the discharge pipe 8, and the asphalt cannot be discharged through the discharge pipe 8. When controlling the asphalt discharge, the movable plate 101 in the installation chamber 92 can also be controlled by the control panel 107. When the movable plate 101 is controlled to move left and right, the air duct 6 and the discharge pipe 8 at the bottom of the movable plate 101 will also move accordingly, ensuring that the asphalt is directly injected into the crack without changing the path of the vehicle plate 1. The bellows 5 blows air into the crack through the air duct 6, blows out the dust and stones in the crack, and then scrapes them off through the dust scraper 4, thereby improving the quality of subsequent road repair.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
