A cone crusher used in mining

Abstract

The invention relates to the technical field of mining machinery, and discloses a cone crusher used in mining, including a machine cover and an inner frame installed inside the machine cover, a feeding hopper is fixedly installed on the top of the machine cover, and a part of the machine cover There is a transmission shaft protruding into the side, and a main shaft bushing whose bottom engages with the transmission shaft is installed on the inner sleeve of the frame. The inner ring of the main shaft bush is movably connected with a fixed sleeve. The inner ring of the sleeve is fixedly sleeved with a main shaft, and the inner wall of the top of the machine sleeve is fixedly installed with a static cone. A uniform spiral is fixedly installed with a spiral convex line, and a pressure plate is fixedly installed between the inside of the main shaft bushing and the bottom of the main shaft. By setting the concentric movable cone structure and matching the design of the hydraulic oil hole, the Crushing effect and efficiency, while ensuring safety.

Description

technical field [0001] The invention relates to the technical field of mining machinery, in particular to a cone crusher used in mining. Background technique [0002] Stone is a necessary material in construction, but according to different application backgrounds, stone particles of different sizes need to be used. Therefore, when mining, stones need to be processed, classified, stored and transported for use. Small stones are It is obtained by crushing large stones. The commonly used crushing equipment is a crusher, and the cone crusher is one of them. It uses a motor to drive the eccentric sleeve to rotate through the transmission device, and the moving cone rotates and swings under the force of the eccentric shaft sleeve. The section where the movable cone is close to the static cone becomes the crushing chamber, and the material is crushed by repeated extrusion and impact of the movable cone and the static cone.

[0002] Stone is a necessary material in construction, but according to different application backgrounds, stone particles of different sizes need to be used. Therefore, when mining, stones need to be processed, classified, stored and transported for use. Small stones are It is obtained by crushing large stones. The commonly used crushing equipment is a crusher, and the cone crusher is one of them. It uses a motor to drive the eccentric sleeve to rotate through the transmission device, and the moving cone rotates and swings under the force of the eccentric shaft sleeve. The section where the movable cone is close to the static cone becomes the crushing chamber, and the material is crushed by repeated extrusion and impact of the movable cone and the static cone. This kind of crusher has a large crushing ratio and high production efficiency, but there are still some problems. :

[0003] The current cone crusher uses the eccentric sleeve to drive the movable cone to rotate for crushing. During the process, the circular distance between the movable cone and the static cone decreases and increases, so that although the distance between the rotating center decreases and the crushing is possible, the other side The distance between them will be very large, so that it is easy to make the larger stones fall down, which cannot reach the required standard, and the use of eccentric rotation will cause shaking, which is easy for the entire mechanical equipment. It is loose everywhere, reducing its strength and there is a certain danger. It also needs frequent inspection and repair equipment. Moreover, this eccentric design also needs to be installed with eccentric sleeves inside the body, which makes the wall thickness of the installed casing uneven. Under the influence of the rotating force, the thinner sleeve wall is prone to cracking due to its high strength, which will also increase the danger. At the same time, frequent inspections and maintenance are required to waste time and reduce production efficiency.
