新型悬挂式压电振动料斗

Suspension type piezoelectric vibro-hopper

Abstract

A suspended piezoelectric vibration-type charging hopper unit for the vibration feeding system is composed of a charging hopper, a charging chute above said charging hopper, and a vibration device consisting of elastic part, piezoelectric ceramic and AC power supply. Its advantages are low consumption of energy, no fatigue failure of elastic part and low cost.
本发明涉及一种振动送料装置中的振动料斗,特别是涉及一种悬挂式压电驱动的振动料斗。其目的是提供一种改进结构的新型悬挂式压电振动料斗,以克服目前压电振动料斗存在的能量消耗较大、弹性元件易产生疲劳断裂、成本高等上述缺点。它包括料槽4、振动装置和料斗1,其特征在于所说的振动装置由弹性元件6和固定在其上的压电陶瓷片5及联接压电陶瓷片5的交流电源组成,料槽4通过连接件7悬挂在料斗1上,并使之能在垂直平面内自由运动,所述的弹性元件6的下端固定在料槽4的侧壁上,上端悬空,且与料槽4水平面成一定角度。
