Dual-machine self-synchronous drive balanced type vibration crusher

Abstract

The invention belongs to the field of self-synchronous machines, and provides a dual-machine self-synchronous drive balanced type vibration crusher. The dual-machine self-synchronous drive balanced type vibration crusher comprises two sets of vibration exciters, two sets of main vibration springs, two supporting bodies, two jaw plates, two sets of damping springs and a vibration isolator; by usinga dual-machine self-synchronous principle to drive, when materials are crushed, eccentric rotors are driven by alternating current motors to enable the two vibration exciters to perform reverse high-speed rotation, the exciting force is generated, and thus two moving jaws are driven to achieve relative motion of antiphase, the force in the horizontal direction of the two moving jaws is counteracted mutually, and a self-balancing state is achieved; and loading transmitted in the horizontal direction is guaranteed to be smallest, and meanwhile material crushing between the two moving jaws is achieved. According to the dual-machine self-synchronous drive balanced type vibration crusher, a subresonance principle and a dual-vibration-exciter self-synchronous principle are combined, a vibrationcrushing way is used for achieving great crushing strength of the crusher, the stability of a system is improved, and the energy conservation of the crusher is achieved. The dual-machine self-synchronous drive balanced type vibration crusher can achieve a relatively large crushing ratio, and can crush ultra-hard materials.

Description

technical field [0001] The invention belongs to the field of self-synchronous vibrating machinery, and relates to a dual-machine self-synchronously driven balanced vibrating crusher. Background technique [0002] A crusher is a device that crushes mined natural stone according to specific requirements. In 1858, American engineer E.W.Blake invented and manufactured the first jaw crusher; the traditional jaw crusher is widely used in various fields of industry because of its advantages of convenient operation, simple structure, easy maintenance, reliable operation and low price. There are a wide range of applications. The vibrating crusher uses the principle of vibration to generate the exciting torque through the vibrating motor, so that the stones vibrate according to a certain rule, and the materials are crushed through mutual collision and friction. Since the appearance of the first crusher, the production efficiency of the factory has been improved to a certain extent. ...

Problems solved by technology

[0004] At present, the currently used crushers still have the following disadvantages: the crushing chamber has only one movable jaw body, which is driven by a motor to work in one direction, and its vertical stroke is relatively large. Suffering local grinding and peeling, thus giving a reaction force to the jaw plate and making the jaw plate easier to wear. At the same time, most crushers use high-power motors as power sources, and the energy consumption acc
