Screening device for reproduction of mixture for petroleum asphalt

Abstract

The invention discloses a screening device for reproduction of a mixture for petroleum asphalt and relates to the technical field of petroleum asphalt. The screening device for reproduction of the mixture for the petroleum asphalt comprises a rack. A reduction motor is arranged on the top of the left wall of the rack. An output shaft of the reduction motor is fixedly connected with one end of a driving rod through a coupling. The end, far away from the reduction motor, of the driving rod is movably connected to the interior of the top of the left side of the left wall of the rack. The drivingrod is sleeved with eccentric rotating wheels. The bottoms of the eccentric rotating wheels are slidably connected with the top of a contact plate. The screening device drives a lower linkage mechanism to do repeated front-back motion through cooperation of the reduction motor, the driving rod, the eccentric rotating wheels, an upper box mechanism and a lower box and through cooperative arrangement of a transverse shaking mechanism. The problems that a vibration mechanism is poor in shaking stability and short in service life in the prior art are effectively solved.

Description

technical field [0001] The invention relates to the technical field of petroleum asphalt, in particular to a screening device for reproducing petroleum asphalt mixture. Background technique [0002] After the asphalt pavement is aging, it can also be recycled and regenerated. The quality of the recycled material can be effectively controlled by screening. For example, the Chinese authorized patent announcement number is: CN205917571U, a kind of multi-directional screening equipment for recycling recycled materials on asphalt pavement, including inclined settings. Screen box, the screen box is set on the load-bearing pier through the spring assembly, and the spring assembly is respectively set on the lower and upper parts of the two sides of the screen box. When the screen box performs multi-directional compound helical vibration, it is beneficial to the multi-directional movement of small particles of asphalt in the screen assembly, but the stability of the components used t...
