Description
Technical Field
The utility model relates to a sieving mechanism, in particular to broken sieving mechanism of recycled concrete.
Background
The regenerated concrete is prepared by crushing, cleaning and grading waste concrete blocks, mixing the crushed, cleaned and graded waste concrete blocks with a grading agent according to a certain proportion, partially or completely replacing natural aggregates (mainly coarse aggregates) such as sand stones and the like, and adding cement, water and the like. The recycled concrete can be combined into aggregates in the following cases: all aggregates are regenerated aggregates; the coarse aggregate is regenerated aggregate, and the fine aggregate is natural sand; the coarse aggregate is natural gravel or cobble, and the fine aggregate is regenerated aggregate; the reclaimed aggregate replaces part of the coarse aggregate or the fine aggregate.
After the concrete waste is crushed, the crushed waste needs to be screened, fine sand mixed in the waste is screened out and recycled, the resource utilization rate is improved, and the production cost is reduced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a broken sieving mechanism of recycled concrete carries out twice screening in to the waste material with the broken back of concrete waste material, and several kinds of different particle diameters in the concrete waste material are taken out to the sieve to solve the problem that proposes in the above-mentioned background art.
The purpose of the utility model is realized like this: the utility model provides a broken sieving mechanism of recycled concrete, is including smashing district and screening district, the upper end in smashing the district is equipped with the feed inlet, the feed inlet below is equipped with two sets of crushing rollers, and is two sets of the below of smashing the roller is equipped with the delivery board, the screening district with smash the district and pass through the breach intercommunication, be provided with upper screen plate and lower screen plate in the screening district, the downside both ends of screen plate pass through the spring respectively with two sets of backup pad elastic connection down, upper screen plate with lower screen plate passes through connecting rod fixed connection, upper screen plate sets up in delivery board discharge end below, the bottom of screening district is equipped with the motor, the output shaft transmission of motor is connected with the pivot, is connected with the cam in the pivot, and the cam laminating is in the bottom of screen plate down, rotates through the cam and drives the screen plate vibrations down.
As the utility model discloses a further inject, the inner wall bilateral symmetry in crushing district is equipped with the abrasive disc.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model discloses a two sets of sieve sieves the concrete waste material after smashing, sieve out the fine sand that the quality is higher in the waste material, not only improved resource utilization, and the fine sand quality that sieves out is better moreover, recycles these fine sands of good quality, has guaranteed the engineering quality standard;
2. the utility model discloses simple structure is practical, through the motor drive cam, makes the sieve vibration sieve, and spring coupling is passed through to lower sieve and backup pad, not only satisfies the theory of operation of vibration sieve, plays the guard action to the sieve moreover, has prolonged the life of sieve.
