Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-Figure 4 A granular asphalt screening device for asphalt, comprising a sieve plate 1 and a bottom plate 2. The top of the sieve plate 1 is open for asphalt raw materials to enter. The bottom plate 2 is connected to a vibration frame 3 through a vibration mechanism. The vibration mechanism is used to drive the vibration frame 3 to shake up and down. The vibration frame 3 is rotatably connected to a support plate 4 through a positioning mechanism 5. The support plate 4 is rotatably connected to one end of the sieve plate 1.

[0026] Specifically, the positioning mechanism 5 includes a positioning slider 502, the positioning slider 502 is rotatably connected to the support plate 4 through a rotating shaft, the positioning slider 502 is slidably connected to the inner wall of the positioning slide groove 503, the positioning slider 502 is threadedly connected to the positioning screw 501, the positioning screw 501 is connected to the driving motor, and the driving motor is connected to the controller; the positioning mechanism 5 drives the support plate 4 to move by driving the movement of the positioning slider 502, so as to adjust the inclination angle of the screen plate 1, and when the vibration mechanism drives the vibration frame 3 to shake up and down, it can drive the right corner of the screen plate 1 to shake up and down, and rotate up and down with the center point of the support 6 as the center, thereby realizing the shaking of the asphalt raw material in the screen plate 1, realizing the separation of the asphalt raw material, and the small particles of raw material enter the second collection box 10 at the bottom from the sieve hole, and the large particles of raw material remain on the screen plate 1 and finally enter the first collection box 9;

[0027] It should be noted that one end of the sieve plate 1 away from the support plate 4 is rotatably mounted on the support 6, the support 6 is fixedly mounted on the guide plate 7, the upper surface of the guide plate 7 is set as an inclined surface inclined downward, the lowest end of the inclined surface is inserted into the first collection box 9, the upper surface of the guide plate 7 is located at the lower side of the sieve plate 1, the guide plate 7 is fixedly mounted in the first collection box 9, and the guide plate 7 is located above the vibration frame 3. Specifically, the vibration frame 3 is fitted with the outer surface of the first collection box 9, and the vibration frame 3 is slidably connected with the inner wall of the first collection box 9;

[0028] like Figure 1As shown, the asphalt raw material left on the screen plate 1 reaches the position of the guide plate 7 from the left side. In order to prevent the raw material from splashing out from the guide plate 7, two side plates 8 are fixedly installed on both sides of the guide plate 7. One end of the two side plates 8 is in contact with the outer wall of the first collecting box 9. The two side plates 8 are arranged on both sides of the vibration frame 3, and the side plates 8 and the vibration frame 3 can slide up and down relative to each other.

[0029] Furthermore, in order to collect asphalt particles falling from the screen plate 1, a second collecting box 10 is provided on the lower side of the screen plate 1, and the second collecting box 10 is installed on the bottom plate 2;

[0030] It should be noted that a discharge port is provided at one end of the sieve plate 1 close to the first collecting box 9, and a baffle 11 is installed at the position of the discharge port. The baffle 11 is connected to a lifting mechanism 12 for driving it to move up and down. The baffle 11 has at least two states driven by the lifting mechanism 12, wherein the two states are a sealed state and a discharge state. In the sealed state, the sieve plate 1 forms a closed square frame structure, and the asphalt raw materials therein will not be screened out from the sieve plate 1 during the shaking process. In the discharge state, the discharge port is opened, and the asphalt particles remaining in the sieve plate 1 enter the first collecting box 9 from the inclined sieve plate 1 through the guide plate 7. When the discharge port is opened, the opening height can be slightly larger than the size of the asphalt particles, so that the asphalt particles can enter the first collecting box 9 in an orderly and phased manner, and the discharge speed is slowed down, but the impact on the inner wall of the first collecting box 9 is relatively small.
