AI Technical Summary
In existing technologies, yellowish-brown weathered aggregates are prone to clumping and have a high mud content, which causes large-diameter crushed stones to get stuck in the grate holes, affecting the filtration effect and requiring manual cleaning at regular intervals, which is time-consuming and labor-intensive.
Design an asphalt aggregate screening device, including a frame, a conveying assembly, a screening plate and a cleaning assembly. The screening plate is inclined and the cleaning assembly is slidably connected along the conveying direction. Impurities in the screening holes are automatically cleaned by a toggle or a rake, realizing the automated and timely cleaning of crushed stone.
It enables automated and timely cleaning of crushed stone inside the screening holes without manual intervention, thereby improving work efficiency and reducing labor costs.

Abstract
Claims
1. An asphalt aggregate screening apparatus, characterized by, include: frame; A conveying assembly, rotatably connected to the frame and extending horizontally, is used for conveying aggregate; A screening plate is disposed on the frame and located above the input end of the conveying component. The screening plate extends downward gradually from the side away from the input end of the conveying component to the side closer to the input end of the conveying component. Screening holes extending along the conveying direction of the conveying component are provided through the screening plate for screening aggregates. as well as A cleaning component is slidably connected to the frame along the conveying direction of the conveying component and located above the screening plate. The cleaning component penetrates downward through the screening hole and can move toward the input end of the conveying component to clean impurities in the screening hole.
2. The asphalt aggregate screening apparatus of claim 1, wherein, The frame is provided with two baffles located on both sides of the conveying component and used to block the aggregate. The surface of the baffles extends in the vertical direction. The screening plate is disposed between the two baffles. The cleaning component is slidably connected to the baffles.
3. The asphalt aggregate screening apparatus of claim 2, wherein, The cleaning component includes: A support bracket, slidably connected to the baffle along the conveying direction of the conveying assembly and located above the screening plate; and An actuating element is connected to the bracket and extends downward through the screening hole.
4. The asphalt aggregate screening apparatus of claim 3, wherein, The bracket is provided with a sliding buckle that is attached to the upper edge of the baffle.
5. The asphalt aggregate screening apparatus of claim 3, wherein, The actuating component is a rake claw, the lower end of which has an upwardly bent hook. The cleaning component can drive the rake claw to move closer to the input end of the conveying component and cause the hook to gradually hook impurities to the outside of the screening hole.
6. The asphalt aggregate screening apparatus of claim 2, wherein, The two baffles are connected by two support strips spaced apart along the conveying direction of the conveying assembly. The screening plate is mounted on the support strips, and the top of the support strips is provided with an insert post that extends upward through the screening plate.
7. The asphalt aggregate screening apparatus of claim 6, wherein, A guide plate is connected to the support strip near the input end of the transmission component. The guide plate extends gradually downward from the side near the support strip to the side away from the support strip.
8. The asphalt aggregate screening apparatus of claim 3, wherein, The frame is provided with a telescopic member extending along the conveying direction of the conveying assembly, and the extended end of the telescopic member is connected to the support.
9. The asphalt aggregate screening apparatus of claim 8, wherein, The bracket is bolted to a connecting seat, and the telescopic component is connected to the connecting seat.
10. The asphalt aggregate screening apparatus of claim 9, wherein, The expansion joint is fitted with a flexible corrugated tube on its outer periphery. One end of the flexible corrugated tube is connected to the connecting seat, and the other end is connected to the outer peripheral wall of the expansion joint.
