Multistage and staged stone crushing equipment

Abstract

The invention discloses multistage and staged stone crushing equipment which comprises an outer frame body, a motor box, a fixing sleeve, a lead screw, a moving block, a mounting plate, a first hinge seat and a stone crushing mechanism, a conveying channel is mounted on the low wall in the outer frame body, a supporting plate is mounted at the top of the conveying channel, and a stone crushing cavity is fixedly mounted at the top end of the supporting plate. A stone falling hole communicating with the interior of the stone crushing cavity and the conveying channel is formed in the center of the supporting plate, and a sieve plate is mounted at the top in the stone falling hole. According to the equipment, an extrusion block firstly makes contact with stone in the stone crushing cavity, then a pressing plate makes secondary contact, the crushing efficiency is improved, a movable block indirectly drives a push plate to synchronously move when moving, then linkage adjustment of a lifting plate and the push plate is achieved, and a movable plate can achieve the effect of extruding and crushing the stone in the stone crushing cavity; and meanwhile, the stone in the stone crushing cavity can make full contact with a mounting column and first crushing teeth outside the extrusion block through movement of the movable plate, and the stone crushing efficiency is further improved.

Description

technical field [0001] The invention belongs to the technical field of crushing equipment, and in particular relates to a multi-stage and stage-by-stage crushing equipment. Background technique [0002] Stone crushers are also called crushers. According to the principle of crushing, the commonly used crushing machines for heavy mining machinery include jaw crushers, impact crushers, vertical impact crushers, hydraulic cone crushers, ring hammer crushers, and hammer crushers. Crusher, roll crusher, compound crusher, cone crusher, double-stage crusher, gyratory crusher, mobile crusher, etc. The construction industry will choose different stone crushers to crush stones according to their needs.

Problems solved by technology

[0003] In the existing construction industry, a large amount of stones are often needed for concrete mixing. Most of these stones are processed by stone crushers. When traditional stone crushers work, the internal stone crushing mechanism often only It can carry out a single crushing operation, and unqualified products need to be crushed repeatedly, which undoubtedly reduces the efficiency of crushing, and because some buildings also use sand and gravel, the crushing accuracy is often higher. In this way, the traditional If the crusher cannot achieve multi-stage crushing, it cannot crush stones and gravel at the same time. In view of the above problems, an effective solution is urgently needed.
