Conical crusher

Abstract

The invention relates to a crusher for crushing stones. The technical problem to be solved is that the crusher has the characteristics of high production efficiency, simple structure and small volume, and can be started in a full-load mode and subjected to stepless regulation. In the technical scheme, the conical crusher comprises a fixed cone which is provided with an inner conical roll compacting surface and is fixed to a machine frame, a movable cone which is provided with an outer conical roll compacting surface and can be positioned on a spherical support in a sliding mode and a hydraulic power system for driving the movable cone to move, wherein the roll compacting surface of the movable cone is encircled by the roll compacting surface of the fixed cone, and keeps a certain roll compacting interval with the roll compacting surface of the fixed cone. The conical crusher is characterized in that the hydraulic power system comprises a plurality of oil cylinders for pushing the movable cone to move, an oil distributor for controlling the oil cylinders to move sequentially and an oil pump for conveying hydraulic oil to the oil cylinders and the oil distributor by an oil passage; and a plurality of oil cylinders are positioned between the movable cone and the machine frame radially and regularly.

Description

technical field [0001] The invention relates to a mining machine, in particular to a crusher used for crushing stones. Background technique [0002] Crusher is a conventional mining machinery used to crush stones to the required specifications to meet the needs of mining production. The structure of conventional cone crusher is as follows: Figure 6 As shown: the motor 15 is driven to the conical gear pair 12 through the belt 13, and then drives the eccentric shaft sleeve 11 to rotate, so that the crushing motor cone 2 makes a circuitous movement (cone swing) according to the spherical support center 2-2, and the rolling and pressing of the moving cone The stone rolling between the surface 2-1 and the fixed cone rolling surface 1-1 makes the volume of the stone small to the required specification. [0003] The defects of this kind of mechanism are: 1. The finish machining of the frame is complicated and the assembly precision is high; 2. Restricted by the eccentric sleeve r...

AI Technical Summary

Problems solved by technology

[0003] The defects of this kind of mechanism are: 1. The finish machining of the frame is complicated and the assembly precision is high; 2. Restricted by the eccentric sleeve rotating pair, the moving frequency of the moving cone is limited (250-350 / min), which affects the output 3. The existence of the eccentric sleeve causes the vibration of the equipment, which affects the service life of the parts; 4. Due to the large radial load of the rotating pair of the eccentric sleeve, it causes serious heating, resulting in a complex structure of the lubrication and cooling system (occupancy power 7.5-15KW ); and the volume is larger, the product cost is higher
