Low-loss building stone smashing device for construction site

Abstract

The invention discloses a low-loss stone crushing device for construction sites, which includes a box body; a partition is fixed on the upper part of the inner cavity of the box, an electric heating plate is arranged on the inner cavity wall of the box body above the partition, and a through hole A flip-type cover plate is arranged at the bottom; two chutes are arranged symmetrically under the partition, and the chutes are arranged inclined inward; a spray pipe is arranged above the chute; Crushing rollers, the gap between the crushing rollers on both sides is facing the sliding opening formed by the chute; a screen is arranged under the crushing rollers, and the screen is movably embedded on the side wall of the inner cavity of the box, and the bottom of the screen is A spring is connected between the two ends and the inner cavity wall of the box, and an exciter is installed at the bottom of the screen. The crushing device of the present invention makes the stone easy to crush by performing thermal expansion and contraction treatment on the stone, thereby reducing equipment loss and prolonging the service life of the equipment.

Description

technical field [0001] The invention relates to the construction industry, in particular to a low-loss stone crushing device for construction sites. Background technique [0002] With the continuous development of the construction industry, the use of stone in the construction industry is also increasing. Before the use of stone, it is necessary to crush large blocks of stone. In the process of stone crushing, stone crushing is the most used device. The stone crushing device is a kind of equipment that crushes stones by mechanical action. It is widely used in the construction industry. After the stone crushing machine crushes the stones, the stones are used in building construction. [0003] Most of the existing stone crushing devices put the stone directly into the device and then use the crushing parts to crush the stone when crushing the stone. Due to the high hardness of the stone itself, the crushing part wears a lot during the crushing process, and at the same time T...

Problems solved by technology

[0003] Most of the existing stone crushing devices put the stone directly into the device and then use the crushing parts to crush the stone when crushing the stone. Due to the high hardness of the stone itself, the crushing part wears a lot during the crushing process, and at the same time The load on the motor is also relatively large, which affects the service life of the crushing parts and the motor
