One side of the support frame 1 is provided with a first telescopic cylinder 8, and a cylinder body of the first telescopic cylinder 8 is fixedly connected with the support frame 1. The piston rod of the first telescopic cylinder 8 is hinged with the outer barrel wall of the material bearing barrel 3. The outer barrel wall of the material bearing barrel 3 is also provided with a pulley 6, and the support frame 1 is provided with a sliding opening 7 for the pulley 6 to slide. The first telescopic cylinder 8 pushes the material-bearing barrel 3 to move along the length direction of the sliding opening 7. The sliding port 7 comprises a straight sliding port 72 and a curved sliding port 71, the curved sliding port 71 is positioned at one side of the straight sliding port 72 close to the cylinder body of the first telescopic cylinder 8, and the curved sliding port 71 is arranged in a downward bending mode.

The first telescopic cylinder 8 drives the material-bearing barrel 3 to move, when the pulley 6 is at the curved sliding opening 71, the barrel bottom of the material-bearing barrel 3 is abutted against the top surface of the weighing platform 2, so that the weighing platform 2 bears the weight of the material-bearing barrel 3. When the pulley 6 enters the straight sliding opening 72 from the curved sliding opening 71, the bottom of the material receiving barrel 3 is separated from the top surface of the weighing platform 2, so that the support frame 1 bears the weight of the material receiving barrel 3.

Referring to fig. 4 and 5, a discharge opening 9 is opened at the bottom of the material receiving barrel 3. A baffle 10 is arranged in the discharge opening 9, one side of the baffle 10 is hinged with the material bearing barrel 3, a placing groove 11 is formed in the other side of the material guide plate 16, and a roller 12 is rotatably connected in the placing groove 11.

When the pulley 6 enters the straight sliding port 72 from the curved sliding port 71, the bottom of the bucket 3 is separated from the top surface of the weighing platform 2. The baffle 10 is rotated downwards by a certain angle under the action of gravity, and simultaneously the asphalt mixture in the material bearing barrel 3 is pressed on the baffle 10, so that one side of the baffle 10 is abutted against the top surface of the weighing platform 2.

The material guide groove body 13 is obliquely arranged, the highest point of the material guide groove body 13 is lower than the highest point of the weighing platform 2, and the material guide groove body 13 abuts against one side of the weighing platform 2.

After the asphalt mixture in the material bearing barrel 3 is discharged from the discharge opening 9, the asphalt mixture enters the material guide groove body 13, and the asphalt mixture is discharged to a corresponding position through the inclined direction of the material guide groove body 13.

The implementation principle of the metering device for the asphalt mixture in the embodiment of the application is as follows: when weighing is needed, the first telescopic cylinder 8 is started to pull the material bearing barrel 3. After the pulley 6 enters the bend slip port 71, the first telescoping cylinder 8 is closed. At this time, the asphalt mixture is added into the material bearing barrel 3, and the weight of the asphalt mixture is measured out through the weighing platform 2.

After weighing is completed, the second telescopic ram 143 is started according to the height of the container filled with the asphalt mixture as required. The second telescopic cylinder 143 pushes the push plate 142 to move upward, thereby moving the material receiving tub 3 and the material guide chute body 13 upward. The discharge end of the material guide groove body 13 is aligned with the feeding position of the container.

Then the first telescopic cylinder 8 is started to push the material-bearing barrel 3. When the pulley 6 enters the straight sliding opening 72 and the pulley 6 is positioned at one end of the straight sliding opening 72 far away from the curved sliding opening 71, the first telescopic cylinder 8 is closed. The flap 10 is now rotated downwards by gravity, thereby opening the discharge opening 9.
