[0017] The present invention has the following beneficial effects:

[0018] 1. The side circumference of the adjustment plate adopts an arc surface design. The push rod assembly reciprocates with the rotation of the adjustment plate, and the other end of the push rod assembly collides with the discharge pipe at the extreme position; the push rod assembly continuously knocks on the barrel discharge pipe to assist in the transportation of asphalt, thereby avoiding the occurrence of asphalt blockage in the barrel discharge pipe.

[0019] 2. First, turn the screw so that the screw drives the pressure plate upward with the help of the thread, and then pull the two pull rods so that the two pull rods respectively drive the two sponge blocks to move away from each other. Then place the connecting frame between the pressure plate and the fixed sleeve, and then pull the connecting frame so that the connecting frame drives the square frame to move. When the square frame drives the arc block to move and contact the surface of the adjustment plate, reverse the screw so that the screw drives the pressure plate to be squeezed on the connecting frame with the help of the thread, thereby achieving the effect of quickly fixing the connecting frame. At this time, release the pull rod, and the second spring will give the pull rod elastic force, so that the pull rod drives the sponge block to move and contact the arc surface of the adjustment plate. Then start the motor, which drives the adjustment plate to rotate. The adjustment plate rotates and starts to squeeze the push rod. At this time, the push rod will be affected by the elastic force of the first spring. The upper end of the push rod will always contact the arc surface of the adjustment plate. The up and down movement of the push rod will hit the discharge pipe of the material barrel, thereby achieving the effect of assisting the asphalt in the discharge pipe to flow out quickly. When the adjustment plate rotates, the sponge block will always be in contact with the arc surface of the adjustment plate, achieving the effect of cleaning the surface of the adjustment plate. By setting up the auxiliary structure, the effect of assisting the asphalt to flow out of the discharge pipe of the material barrel quickly is achieved, thereby improving the efficiency of the equipment in repairing cracks in municipal bridges.

[0020] The U-shaped fork is driven by the sliding ring to move upwards along the inner wall of the gusset plate, thereby adjusting the position of the cleaning brush. When the cleaning brush moves to the position of the discharge pipe aligned with the material barrel, the driving rod is rotated to drive the U-shaped fork to move with the help of the thread. The U-shaped fork is squeezed on the surface of the gusset plate at this time, thereby fixing the position of the slip ring. The cleaning brush is then pushed to be inserted into the discharge pipe of the material barrel to dredge and clean the inside of the discharge pipe of the material barrel. After cleaning, the cleaning brush is released. At this time, the third spring will give the cleaning brush elastic force to return the cleaning brush to its original position. The driving rod is then reversed to disengage the U-shaped fork from the surface of the gusset plate. The slip ring is then slid downwards along the gusset plate, thereby temporarily fixing the position of the cleaning brush. By setting the cleaning structure, the cleaning brush position can be easily fixed and the cleaning inside the discharge pipe of the material barrel can be easily cleaned.

[0021] 4. By setting up the support structure, when it is necessary to pour asphalt into the barrel, the pin is rotated to make the pin rotate out from the inner wall of the slot of the support plate, and then the barrel cover is pulled to move the barrel cover upward. At this time, the barrel cover drives the support plate to move upward, and the guide rod will slide along the inner wall of the limit block. The guide rod has the effect of limiting the movement position of the barrel cover. When the barrel cover moves to the appropriate position, the pin is reversed so that the pin is squeezed into the slot of the support plate with the help of the thread, thereby achieving the effect of fixing the position of the support plate. At this time, asphalt can be poured from the gap between the barrel cover and the barrel. By setting up the support structure, the operator can quickly pour asphalt into the barrel, thereby improving the work efficiency of the operator. BRIEF DESCRIPTION OF THE DRAWINGS
