A screening device for road asphalt recycling

Abstract

The invention relates to a screening device for road asphalt recycling, which comprises a supporting leg, on which a processing frame is installed, and a material inlet is arranged on the upper and lower sides of the processing frame, and the lower end surface of the processing frame is a downwardly inclined structure from back to front , and the lower side of the front end of the processing frame is provided with a discharge port, and the inside of the processing frame is sequentially provided with a crushing mechanism and a screening mechanism from top to bottom. The present invention can solve the following problems existing in the recycling process of the existing road asphalt. It is necessary to manually crush the recycled block structure asphalt. Manually crushing the road asphalt block is labor-intensive, and the dust generated by the crushing is breathed into the body and is harmful to the human body. Large, manual screening of the crushed asphalt is not thorough, and it is necessary to reciprocate the crushing process of the asphalt blocks that do not meet the specifications, and the operation is complicated.

Description

technical field [0001] The invention relates to the related technical field of road asphalt recovery, in particular to a screening device for road asphalt recovery. Background technique [0002] Asphalt pavement is usually used as the pavement surface layer, which is directly affected by vehicle load and atmospheric factors. At the same time, the physical and mechanical properties of asphalt mixture are greatly affected by climate factors and time factors. To provide stable and durable service, the asphalt pavement needs to be maintained after long-term use, and the road asphalt needs to be recycled during the maintenance. When recycling the road asphalt, the asphalt pavement is divided into blocks and then crushed and screened. The road asphalt is processed to complete the recovery of asphalt. When the asphalt pavement is recycled, the specifications of the asphalt pavement material after crushing and screening affect the quality of asphalt recovery; [0003] However, the ...
