Building stone crushing and screening all-in-one machine

Abstract

The invention relates to the technical field of building stone machining, in particular to a building stone crushing and screening all-in-one machine which comprises a machining box. A feeding port and a discharging port are formed in the upper end and the lower end of the machining box correspondingly, crushing rollers are symmetrically and rotationally installed in the machining box, and a screen is movably installed below the crushing rollers. A breaking mechanism is arranged over the crushing rollers and comprises a breaking roller, a guide sleeve plate and a gear, a first sliding block and a second sliding block are mounted in the machining box from top to bottom in a sliding manner, the two ends of the breaking roller are rotationally mounted in the first sliding block and the second sliding block correspondingly, the guide sleeve plate is fixedly mounted in the machining box, and the gear is arranged on the inner side of the guide sleeve plate. According to the building stone crushing device, the size of broken stones is smaller, the phenomenon that the stones are clamped in the gap between the breaking roller and the machining box is avoided, and the breaking effect on the stones is further improved.

Description

technical field [0001] The invention relates to the technical field of building stone processing, more specifically, an integrated machine for crushing and screening building stones. Background technique [0002] Crushed stones are often used in construction projects, most of which are obtained by crushing large stones, and the use of crushing and screening integrated machines is very common in recent years. [0003] When the crushing roller in the existing all-in-one crushing and screening machine for stones works for a long time, large stones often get stuck in the gap between the crushing roller and the inner wall of the body, which affects the later stone crushing work. Contents of the invention [0004] The object of the present invention is to provide an all-in-one machine for crushing and screening building stones, so as to solve the problems raised in the above-mentioned background technology. [0005] To achieve the above object, the present invention provides th...
