Lateral diagonal piezoelectric vibration feeder

The invention provides a lateral diagonal piezoelectric vibration feeder, comprising a base, a vibration device, a hopper and a support structure, wherein the vibration device comprises a piezoelectric bimorph, a resonant spring and a vibrating body, the piezoelectric bimorph is formed in the way that bimorphs are pasted on the front and the back of a substrate, the lower side of the resonant spring is connected with the substrate of the piezoelectric bimorph, the lower side of the substrate of the piezoelectric bimorph is connected with a base, the upper side of the resonant spring is connected with the vibrating body, the hopper is connected onto the vibrating body, a driving source installing angle formed by the piezoelectric bimorph and the resonant spring is 60-78 degrees relative to a horizontal angle; and the support structure is composed of a Yangpu hole substrate and the resonant spring. The lateral diagonal piezoelectric vibration feeder provided by the invention has the advantages of alignment prop
