The storage barrel is embedded in the middle of the top end of the device main body. The upper part of the left side surface of the device main body is fixedly connected with a push rod through a nut. For this asphalt crack filling device for highway maintenance, by installing a screw rod, when the motor is started to rotate, the stirring frame rotates and drives the screw rod to rotate at the same time, so that the asphalt stored in the storage barrel is not easy to coagulate. At the same time, the asphalt will flow towards the first discharge hopper and the second discharge hopper driven by the screw rod. At the same time, the electric telescopic rod is started to drive the second discharge hopper to extend downward and closely fit the road surface crack part, so that there is no gap between the second discharge hopper and the asphalt crack to be filled, and the asphalt is not easy to leak outwards.

[0004] When filling the joints, the filling pipe is generally held by hand. The stability of holding by hand is poor, and the filling position is easy to deviate. During the joint filling process, after filling is completed, or when the pouring is interrupted, the asphalt remaining at the bottom is easy to be omitted, resulting in waste of asphalt. At the same time, it will pollute the road surface and affect the flatness of the road surface. Therefore, an asphalt joint filling device is proposed for the above problems. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art, aiming at the problems that the filling pipe is generally held by hand, the stability of holding by hand is poor, and the filling position is easy to deviate. During the joint filling process, after filling is completed, or when the pouring is interrupted, the asphalt remaining at the bottom is easy to be omitted, resulting in waste of asphalt. At the same time, it will pollute the road surface and affect the flatness of the road surface, the utility model proposes an asphalt joint filling device. After filling is completed, the swing rod is released, and the swing rod swings to the vertical state under the action of the spring, which can block the bottom outlet of the swing rod by the blocking plate, avoid asphalt omission, and reduce asphalt waste. By setting a stable vehicle body as a support point, the distance between the pouring port and the gap can be ensured to be stable.

An air pump is installed on the top side of the vehicle body. The air pump and the air inlet pipe are communicated through a connecting pipe. A rubber hammer is fixed to the bottom end of the pneumatic rod. An air release hole is formed in the outer side of the bottom of the fixed cylinder. In order to make it more convenient for the asphalt to penetrate downward along the crack, pressurized gas is conveyed into the air inlet pipe through the air pump. The pressurized gas can push the pneumatic rod to move downward along the inside of the fixed cylinder. When the top of the pneumatic rod moves to the position of the air release hole, the high-pressure gas is discharged through the air release hole. Driven by the second spring, the pneumatic rod moves upward. In this way, the pneumatic rod moves up and down in a vibrating form.
