Embodiment Construction

[0015] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] figure 1 Among them, the two exciters placed in the box mechanism 3 are installed symmetrically up and down, and an eccentric block is installed on each exciter, and the phase difference is synchronously stabilized at 0°. 6 phase connection. The movable jaw 6 is connected with the box mechanism 3 through the torsion spring 7, and the movable jaw 6 and the fixed jaw 4 are symmetrically installed about the center axis of the box mechanism 3 left and right. The left side of the torsion spring 7 is the feeding port 5, and there are four vibration isolation springs 2, which are installed on the left side of the box mechanism 3 front, rear, left, and right, and the box mechanism 3 is installed on the frame 1. Wherein frame 1 is made by channel steel and steel plate welding.

Abstract

The invention belongs to the field of self-synchronous vibration machinery, and discloses a dual-drive single pendulum type sub-resonance vibration crushing machine. The dual-drive single pendulum type sub-resonance vibration crushing machine includes a machine frame, vibrate-isolation springs, a box body mechanism, a torsion spring, a movable jaw, a fixed jaw, vibration exciters and a master vibration spring. Two eccentric blocks synchronously operate and the phase difference can be stabilized around at 0 degrees when the two vibration exciters symmetrically installed up and down in the box body mechanism works, two alternating current motors drive the eccentric blocks to run in reverse so that force components, in the vertical direction, of generated inertia forces cancel out each other,and the force components, in the horizontal direction, of the generated inertia forces are superimposed each other so as to drive the movable jaw to realize the self-synchronous relative swing, mutual extrusion forces are formed by the movable jaw and a static jaw to achieve the purpose of crushing stones. According to the dual-drive single pendulum type sub-resonance vibration crushing machine,the self-synchronization principle of the sub-resonance double-vibration-exciter, the resonance principle and the double-mass-body vibration principle are combined to realize energy saving of the crushing machine; and by using the double-mass-body vibration principle, the crushing machine has the advantages of large amplitude, large processing capacity, sensitive response to changes in feeding, stable operation and the like.

Description

technical field [0001] The invention belongs to the field of self-synchronizing vibrating machinery, and relates to a sub-resonance vibrating crusher driven by two machines and single pendulum Background technique [0002] The crushing of materials is an indispensable process in the production of products in many industries (such as metallurgy, mining, building materials, chemicals, ceramics, road construction, etc.). Due to the great differences in the physical properties and structures of materials, in order to meet the requirements of various materials, there are various types of crushers. In order to save energy and improve production efficiency, the technical principle of "more crushing and less grinding" is proposed. This makes the crusher develop in the direction of fine crushing, crushing and high efficiency and energy saving. For coarse crushing, no updated equipment has been developed to replace the traditional jaw crusher and gyratory crusher. It is mainly to us...
