Technical Field

[0001] This invention relates to the field of asphalt mixture technology, and more specifically, to an asphalt mixture vibrating screening system. Background Technology

[0002] Asphalt mixture is a composite material composed of multiple components, specifically aggregates of different particle sizes, mineral powder, and asphalt. These components are formed by thorough mixing in a high-temperature environment according to a specific ratio. Due to its excellent performance, this mixture is widely used in road engineering, bridge construction, and other related fields, becoming an indispensable material in modern transportation infrastructure construction. The asphalt mixture vibrating screening system is a core piece of equipment specifically designed for the fine screening of asphalt mixtures. This system can efficiently and accurately separate aggregates of different particle sizes in the mixture, ensuring that each aggregate meets the expected specifications. Through this effective screening process, not only can the uniformity and stability of the asphalt mixture be significantly improved, but its quality can also be fundamentally guaranteed to fully meet various engineering standards and technical requirements, thus providing a solid guarantee for the long-term stability and service life of road engineering projects.

A crushing chamber discharge hopper 29 is fixedly connected to the bottom of the crushing chamber 21. The inner walls of the left and right sides of the crushing chamber 21 are...

The right ends of both crushing roller cylindrical rotating rods 24 extend to the front and rear sides of the right outer wall of the crushing chamber 21.

Crushing rollers 28 are fixedly connected to one side of the inner wall of the crushing chamber 21 for each crushing roller cylindrical rotating rod 24. When screening asphalt mixture is required, firstly, the valve of the discharge hopper 117 at the bottom of the storage bin 116 needs to be opened to allow the asphalt mixture to fall smoothly into the inner side of the screening frame 1110. Simultaneously, the motor 1215 is started, driving the columnar horizontal rotating rod 1213 to rotate. As the columnar horizontal rotating rod 1213 rotates, the third transmission disc 1216 on it also rotates. Through the transmission action of the third track 1217, the fourth transmission disc 1216 is driven. The second columnar horizontal rotating rod 1219 rotates as well. The fifth transmission disc 1221 on the second columnar horizontal rotating rod 1219 drives the sixth transmission disc 26 to rotate through the transmission of the fourth track 27. The sixth transmission disc 26 further drives the rear crushing roller columnar rotating rod 24 to rotate. Due to the meshing between the two gears 25, the front crushing roller columnar rotating rod 24 also rotates. In this way, the two crushing rollers 28 begin to crush the material entering the crushing chamber 21. Meanwhile, the two second transmission discs 1212 on the columnar horizontal rotating rod 1213 drive the two transmission discs 127 to rotate through the transmission action of the second track 1211. The rotation of the transmission discs 127 drives the columnar rotating short rod 124 to rotate, and the columnar rotating short rod 124 further drives the turntable 125 to rotate. The abutment block 126 on the turntable 125 slides in the elliptical slide plate 1222, so that the elliptical slide plate 1222 can move up and down. The elliptical slide plate 1222 drives the lifting rod 1224 to move up and down through the connection of the Z-shaped upright rod 1223. The lifting rod 1224 drives the screen frame 1110 to swing up and down with the columnar transition block 114 as the fulcrum through the linkage action of the pull rod hinge block 1116 and the pull rod 1115. During the up-and-down swinging of the screening frame 1110, the screening mesh 1112 at its bottom performs screening operations on the asphalt mixture. Materials that meet the particle size requirements can pass through the screening mesh 1112 and fall smoothly, while materials that do not meet the particle size requirements remain in the screening frame 1110. When the material in front of the screening frame 1110 accumulates to a certain extent, this material will enter the crushing chamber 21 through the crushing chamber feed funnel 23, where it will be further crushed by the two crushing rollers 28. The crushed material is discharged from the crushing chamber discharge funnel 29 and collected at the receiving frame 119. At the same time, the qualified materials screened out are also collected from the receiving frame 119, ensuring that the classification and processing of materials are carried out efficiently and in an orderly manner.

[0022] Working principle of this invention: When asphalt mixture needs to be screened, firstly, the valve of the discharge hopper 117 at the bottom of the storage bin 116 is opened, and the asphalt mixture falls into the inner side of the screening frame 1110. At the same time, the motor 1215 is started, which drives the columnar horizontal rotating rod 1213 to rotate. The third transmission disc 1216 on the columnar horizontal rotating rod 1213 rotates accordingly, driving the fourth transmission disc 1218 to rotate through the third track 1217, thereby causing the second columnar horizontal rotating rod 1219 to rotate. The fifth transmission disc 1221 on the 19 drives the sixth transmission disc 26 to rotate via the fourth track 27. The sixth transmission disc 26 then drives the rear crushing roller cylindrical rotating rod 24 to rotate. Due to the meshing of the two gears 25, the front crushing roller cylindrical rotating rod 24 also rotates. The two crushing rollers 28 begin to crush the material entering the crushing chamber 21. At the same time, the two second transmission discs 1212 on the cylindrical horizontal rotating rod 1213 drive the two transmission discs 127 to rotate via the second track 1211. The transmission discs 127 drive the cylindrical rotating rod 28 to rotate. When rod 124 rotates, the cylindrical rotating short rod 124 drives the turntable 125 to rotate. The abutment block 126 on the turntable 125 slides within the elliptical slide plate 1222, causing the elliptical slide plate 1222 to reciprocate up and down. The elliptical slide plate 1222 drives the lifting rod 1224 to move up and down via the Z-shaped upright rod 1223. The lifting rod 1224, through the tie rod hinge block 1116 and the tie rod 1115, drives the screen frame 1110 to swing up and down around the cylindrical transition block 114 as the fulcrum. During the up and down swinging process of the screen frame 1110... The bottom screen 1112 screens the asphalt mixture. Material that meets the particle size requirements falls through the screen 1112, while material that does not meet the particle size requirements remains in the screen frame 1110. When the material in front of the screen frame 1110 accumulates to a certain extent, it enters the crushing chamber 21 through the crushing chamber feed hopper 23 and is crushed by two crushing rollers 28. The crushed material is discharged from the crushing chamber discharge hopper 29 and collected at the receiving frame 119. At the same time, the qualified material that is screened out is collected from the receiving frame 119.
