Description

Vibrating screen classifier for asphalt concrete

Technical Field

The application relates to the technical field of screening machines, in particular to a vibrating screening machine for asphalt concrete.

Background

At present, the production raw materials of asphalt concrete comprise gravel, asphalt, stone powder and various additives, and the gravel with different particle sizes needs to be separated in the production and preparation process of the asphalt concrete, and the gravel is usually sieved by using a vibrating sieving machine.

The common screening machine comprises a screen and a vibrating device, wherein the vibrating device comprises a motor, a vibrating connection structure, a vibrating screen flywheel and the like, and is a necessary mechanism for realizing vibration of the vibrating screening machine.

In the above-described related art, the inventors consider that: when the screening machine is used for screening the gravels with different sizes, the tiny gravels are screened out by the screen and put into the proportion of the asphalt concrete raw materials. And bigger grit just directly screens away, and bigger grit just piles up and forms the waste material aside for the utilization ratio of grit is lower.

SUMMERY OF THE UTILITY MODEL

In order to improve the utilization ratio of grit, the utility model aims at providing a vibrating screen extension for asphalt concrete.

The application provides a vibrating screen extension for asphalt concrete adopts following technical scheme:

the utility model provides a vibration screening machine for asphalt concrete, include the frame, set up in sieve case in the frame, be equipped with a plurality of layers of screen cloth on the sieve case, be equipped with the vibration in the frame the sieve case carries out the vibrating device that filters, the sieve case is close to the one end of frame is equipped with grinds the case, it is used for collecting the follow to grind the grit of landing on the screen cloth, it is provided with a plurality of crushing rollers that are used for smashing the grit to grind the incasement rotation, it is equipped with the drive on the case to grind crushing roller carries out kibbling driving piece.

Through adopting above-mentioned technical scheme, when the screening machine carries out the screening to the grit, vibrating device starts, vibrates the screen cloth on the case of will sieving, will pour the grit on the screen cloth into and carry out the vibration screening. The smaller sand and stone pass through the screen mesh and enter the bottom of the screen box, and the larger sand and stone slide into the grinding box along the screen mesh. The roller is smashed with great grit to driving piece drive, and the grit after smashing is collected at grinding incasement, carries out the secondary screening with the grit after grinding incasement crushing again, realizes the reuse of grit. Consequently smash the roller through setting up, utilize the driving piece drive to smash the roller and smash great grit for the grit volume after smashing reduces, so that the grit that reduces once more through the screening of screen cloth, in order to reach the effect of make full use of grit, thereby improves the utilization ratio of grit.
