Cone-shaped crusher rack

Abstract

The invention relates to the field of mine equipment, and discloses a cone-shaped crusher rack. The crusher rack comprises a lower rack and an upper rack, wherein the lower rack comprises a lower rack outer barrel, a lower rack inner barrel and four frame body splice bars, and the lower rack inner barrel is positioned on the center of the lower rack outer barrel; the four frame body splice bars are regularly arranged between the lower rack outer barrel and the lower rack inner barrel, the two adjacent frame body splice bars form a material outlet, and the upper rack comprises a connecting body arranged on the lower rack and a feeding body arranged on the upper part of the connecting body; the feeding body comprises a feeding body outer barrel, a main shaft footstock positioned on the center of the feeding body outer barrel, and two rack arms used for connecting the feeding body outer barrel and the main shaft footstock, a material inlet is formed between the two rack arms, and the material inlet is communicated with the material outlet of the lower rack. Because the sizes of the material inlet and the material outlet are enlarged, the stone flow of the cone-shaped crusher is increased, and the crushing efficiency of the cone-shaped crusher is improved.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a cone crusher frame. Background technique [0002] Cone Crusher is a kind of mining machinery used for crushing stones. Its working principle is to crush stones through mutual extrusion between the movable cone liner and fixed cone liner of eccentric swing. When the cone crusher is working, the stone is fed into the feed port of the upper frame, and after being crushed, it is unloaded from the discharge port of the lower frame. During the whole process, the load and vibration of the cone crusher are very large. Therefore, in order to increase the strength of the frame of the cone crusher, the frame structure of the existing cone crusher is complicated, which leads to the small feed inlet of the upper frame and the discharge port of the lower frame, and the stone flow rate of the cone crusher is relatively small. Little, affecting the production efficiency of the equipment. Con...
