A sliding groove 75 for the baffle 74 to be limited and slidably connected is provided on the right wall of the housing 3.

[0062] In the present utility model, when the asphalt paving operation has not started, the baffle 74 completely separates the passage between the upper storage bin 31 and the lower storage bin 32, blocking the sinking of the asphalt material. When the paving operation starts, the servo motor 72 operates to rotate the screw rod 73, and the baffle 74 moves horizontally outward from the housing 3 along the sliding groove 75, changing the size of the passage between the upper storage bin 31 and the lower storage bin 32, thereby changing the asphalt blanking amount.

[0063] In the present utility model, the servo motor 72 can accurately control the asphalt blanking amount, which can not only block the asphalt material when the paving operation has not started, but also control the asphalt blanking amount during the paving operation, ensuring the paving quality of the paver.
