A single-axis linear motion track vibration device

Abstract

The invention discloses a single-axis linear motion trajectory excitation device, which comprises a vibration box, a base and an eccentric shaft, and the eccentric shaft is arranged on the vibration box; the four corners between the vibration box and the base are respectively provided with a The track change mechanism, the track change mechanism includes a track change lever, a spring, a spring seat and a support shaft; the support shaft is fixed on the vibration box; the track change lever is arranged obliquely between the vibration box and the base, and the track change lever The upper end is vertically hinged on the support shaft, and the lower end is hinged on the base; the upper end of the spring is also vertically hinged on the support shaft, and the lower end is fixed on the base through the spring seat. The notable effect of the present invention is that the circular motion track of the single-axis vibrator is changed into a linear motion track by using the design of the track-changing mechanism, thereby improving the excitation effect and efficiency.

Description

technical field [0001] The invention relates to the technical field of vibrating machinery, in particular to an exciter assembly used in vibrating screens and feeders in mining machinery, and more specifically to a single-axis linear motion trajectory exciter assembly. Background technique [0002] In the crusher industry, the vibrating screen or the feeder, which use a single shaft as the exciter, is the most typical structure and the most widely used model. [0003] The motion trajectory generated by the single-axis vibrator is a circle, and the circular motion trajectory has both normal and tangential vibration components. The advantage of this is that critical materials are not easy to block holes on the screen. However, after the circular motion is combined with the spring motion in the vibrating box, the original motion trajectory is changed. The direct result is that the material only has up and down screening motion, but no horizontal conveying motion (very small hor...
