Automatic multi-stage roller type crusher used for breaking coarse aggregates

Abstract

The invention discloses an automatic multi-stage roller type crusher used for breaking coarse aggregates. The automatic multi-stage roller type crusher used for breaking the coarse aggregates comprises a crusher body; a feeding inlet is fixedly installed at the top end of the crusher body; through mutual cooperation of first-stage double rollers and second-stage double rollers, the coarse aggregates which are not crushed by the first-stage double rollers are brought into the second-stage double rollers to continue to be crushed, and successful crushing of the coarse aggregates is ensured; through a first-stage distribution wheel and a second-stage distribution wheel, the crushed coarse aggregates of different grain diameters are distributed and poured from different distribution outlets, and construction workers can conveniently prepare concrete of different intensities; and through a linkage device, under driving of a same distribution servo motor, a first gear drives a second gear through a gear belt, then the second gear drives a third gear to drive the second-stage distribution wheel, different rotation directions of the first-stage distribution wheel and the second-stage distribution wheel can be achieved, energy is saved, environmental protection is achieved, and the practical effect is remarkable.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to an automatic multi-stage roller crusher for broken coarse aggregate. Background technique [0002] With the continuous expansion of cities and the continuous expansion of buildings and other buildings, building materials such as cement, coarse aggregate and fine aggregate have also increased. Coarse aggregate in building materials in the past few decades has been directly obtained from It is used on the riverbed, but with the acceleration of construction and the promotion of an environmentally friendly green society, the coarse aggregate is now used in Kaishan. The coarse aggregate used at this time is very large and needs to be crushed multiple times before it can be used. Roller Crusher It is one of the multiple crushing methods. Usually, a roller crusher with sawtooth on the surface of both rollers is used to split and tear the material. The existing roller crushers have so...

AI Technical Summary

Problems solved by technology

[0003] 1. The active rollers in the double rollers of the existing roller crusher are protected by a spring protection device. During the rotation of the double rollers, it may cause large aggregates to be discharged without being crushed successfully;

[0004] 2 Coarse aggregates are divided into particle size grades. Coarse aggregates exceeding a certain particle size cannot be used. The traditional roller crusher does not have a material distribution function, so that the coarse aggregate with a particle size up to the standard and the coarse aggregate with a particle size that is not up to the standard are mixed in the Together.;

[0005] 3. Traditional roller crushers cannot separate to obtain multi-level coarse aggregate, which is not convenient for construction workers to prepare concrete with different strengths
