During working, firstly, the waste medium-temperature asphalt mixture is added onto the coarse screening plate 5, then the waste mixture on the coarse screening plate 5 is preliminarily crushed by manually using a hammer or externally extruding the mixture, so that the waste mixture can pass through the coarse screening plate 5, the mixture passing through the coarse screening plate 5 falls to the guide needle 32 under the action of gravity, the mixture which is partially shattered but not shattered in the mixture is separated, and then the mixture passes through the sliding rod 24 and falls to the fine screening plate 18;
the mixture at the fine screening plate 18 is, under the action of the rotating fit slide bar 24 of the cam 9, so that the larger waste mix at the screen portion on the fine screen plate 18 can be supported by the two slide bars 24 corresponding to each other (in the process, part of the larger mix can be crushed in the process of the slide bars 24 approaching each other), and under the combined action of the connecting rod 14 and the transmission rod 15, the cam 9 is driven to move in the vertical direction continuously when in operation, thereby moving the guide plate 29, so that the crushing needle 31 follows the rapid movement in the vertical direction, and during the transmission of cam 9, connecting rod 14 and transmission rod 15, when cam 9 pushes abutment 19 to move downwards, i.e., the fine screening plate 18, moves downward, at this time by the rotation of the rotary shaft 25 and the rotary piece 26, and the position limitation of the lantern ring 27, the two corresponding sliding rods 24 are close to each other, the screened larger waste mixed material is supported, at the moment, one end of the cam 9 is at the lowest position, the crushing needle 31 moves downwards along with the cam, the larger waste mixed material supported by the sliding rods 24 is crushed, in the process, the cam 9 rotates for a circle, the fine screening plate 18 moves up and down in the vertical direction for two times, meanwhile, the two corresponding sliding rods 24 approach to each other and are separated twice, the crushing needle 31 crushes the larger waste mixture supported by the sliding rods 24 once, the process can crush larger waste mixture, and the sliding rod 24 and the fine screening plate 18 are mutually matched and driven, the mixture on the fine screening plate 18 can be stirred and mixed to a certain extent, so that the situation that the meshes of the fine screening plate 18 are blocked is prevented, and the screening effect of the fine screening plate 18 is ensured;
and at the in-process that fine screen board 18 sieves the mixture, preheat board 6 connects the electricity, constantly heat the process of preheating to the mixture of fine screen board 18 department, the heating process of cooperation heating machine 1, make the process of being heated of mixture more even gentle, the problem that rapid heating is difficult to control the temperature has been solved, prevent that the condition of pitch segregation and local aging from taking place, the quality of product has been guaranteed, simultaneously at the broken less mixture of fine screen board 18 department more evenly of being heated, make and preheat the effect better, the mixture after the while heating is broken under the effect of broken needle 31 more easily, both complement each other, the production efficiency and the product quality of product have been increased.
