[0026] refer to Figure 3 The bottom of the front side of the anti-blocking box 3 has a sliding groove 14, and the front side of the transmission frame 9 is slidably connected to the inside of the sliding groove 14.

[0027] As a technical optimization of this utility model, the sliding groove 14 enables the transmission frame 9 to slide more smoothly inside the anti-blocking box 3, reduces the friction between the transmission frame 9 and the anti-blocking box 3, extends the service life of the transmission frame 9, and at the same time limits the movement of the transmission frame 9.

[0028] refer to Figure 2 A vertical groove 15 is provided at the bottom of the right side of the inner cavity of the anti-blocking box 3, and the L-shaped rod 12 is slidably connected to the inside of the vertical groove 15 on the side away from the reciprocating plate 11.

[0029] As a technical optimization of this utility model, the vertical groove 15 enables the L-shaped rod 12 to slide more smoothly inside the anti-blocking box 3, thus preventing the L-shaped rod 12 from deviating.

[0030] refer to Figure 2 Limiting rods 16 are provided on both sides of the front side of the top of the reciprocating plate 11, and the bottom of the limiting rods 16 is fixedly connected to the inner wall of the anti-blocking box 3.

[0031] As a technical optimization of this utility model, the setting of the limiting rod 16 enables the reciprocating plate 11 to move up and down more stably, and at the same time, it has the effect of limiting the movement trajectory of the reciprocating plate 11.

[0038] The working principle and usage process of this utility model are as follows: First, during the material discharge process, the motor assembly 4 is started. The output end of the motor assembly 4 drives the pulley 5 to rotate. The pulley 5 drives the pulley 7 to rotate through the connecting belt 6. The pulley 7 drives the transmission pin 8 to rotate. The transmission pin 8 drives the transmission frame 9 to move up and down. The transmission frame 9 drives the shaped rod 10 to move up and down. The shaped rod 10 drives the reciprocating plate 11 to move up and down. The reciprocating plate 11 drives the L-shaped rod 12 to move up and down. The L-shaped rod 12 drives the impact rod 13 to move up and down, so that the impact rod 13 impacts the discharge slant chamber 2. The vibration generated by the impact shakes off the residual asphalt, thereby preventing the material from easily accumulating and clogging.

[0039] In summary, the asphalt mixing plant used in this highway construction has changed the traditional problem of easy blockage at the asphalt discharge port. By using an impact rod 13 to repeatedly impact the discharge hopper 2, the vibration generated by the impact shakes off the residual asphalt, preventing it from adhering to the wall of the discharge port and thus avoiding blockage. This also prevents the discharge efficiency from being affected.
