Multi-stage efficient stone breaking device

Abstract

The invention discloses a high-efficiency stone crushing device for multi-stage crushing, which comprises a frame body; a material inlet is provided at the center of the rear side of the top plate of the frame body; The left crushing roller and the right crushing roller; the front end of the left crushing roller is eccentrically hinged with a first connecting rod, the front end of the right crushing roller is eccentrically hinged with a second connecting rod, and the lower ends of the first connecting rod and the second connecting rod rotate Connected to the top of the movable block; a connecting column is fixed at the center of the bottom of the movable block, the bottom of the connecting column is connected with a crushing plate, and the first crushing teeth are densely arranged on the lower end surface of the crushing plate; the inner cavity of the frame body A crushing frame is arranged on the bottom plate, and the opening of the crushing frame is facing the crushing plate; a baffle plate arranged obliquely is fixed on the rear side of the inner cavity of the frame. The stone crushing device of the present invention can realize multi-stage crushing of stones, has good crushing effect and high crushing efficiency.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a multi-stage crushing and high-efficiency stone crushing device. Background technique [0002] Ore materials are indispensable materials in the construction field. With the development of science and technology, the requirements for stone materials are getting higher and higher. Most of these stone materials need to be crushed before use, and crushing devices are needed at this time. [0003] China's crushing and grinding equipment industry has fully developed into a highly competitive industry. According to relevant data, as of the end of 2010, there were 431 crushing and grinding equipment enterprises above designated size in China. After rapid development and fierce market competition, the basic pattern has initially formed. [0004] Most of the existing crushing devices on the market can only achieve primary crushing in the process of crushing stones, and the crushing e...
