Pneumatic flat plate vibrator based on Bernoulli principle
The invention belongs to the field of building construction tools, and particularly relates to a pneumatic flat plate vibrator based on the Bernoulli principle. The pneumatic flat plate vibrator comprises a bottom plate, wherein the upper surface of the bottom plate is fixedly connected with an air box through telescopic springs, and the side walls of the two sides of the air box fixedly communicate with an air inlet pipe and an air outlet pipe respectively; the inner top face of the air box is fixedly connected with a horizontally-arranged air plate through vibration springs, and the air plate is composed of an upper deformation plate, a lower deformation plate and a surrounding edge; and the peripheral side walls of the upper deformation plate and the lower deformation plate are fixedlyconnected with the surrounding edge, a sealed air cavity is formed among the upper deformation plate, the lower deformation plate and the surrounding edge, and magnet blocks are embedded in the upperdeformation plate and the lower deformation plate. According to the pneumatic flat plate vibrator based on the Bernoulli principle, the air plate can be driven by high-speed airflow to impact the airbellow in an up-down reciprocating mode to vibrate concrete, and friction is avoided in the reciprocating movement process of the air plate, so that the problems that the energy transfer efficiency isreduced and power is insufficient due to abrasion are avoided, the service life of the air plate is greatly prolonged, and the vibrating effect is good.
本发明属于建筑施工工具领域，尤其是涉及一种基于伯努利原理的风动平板式振动器，包括底板，所述底板的上表面通过伸缩弹簧固定连接有风箱，所述风箱两侧的侧壁上分别固定连通有进风管和出风管，所述风箱的内顶面通过振动弹簧固定连接呈有水平设置的风板，所述风板由上形变板、下形变板和围边组成，所述上形变板和下形变板的四周侧壁均与围边固定连接，且所述上形变板、下形变板与围边之间形成密封风腔，所述上形变板和下形变板内均嵌设有磁铁块。本发明可通过高速气流带动风板上下往复撞击风箱，对混凝土进行振捣，风板往复移动过程中无摩擦，避免因磨损导致能量传递效降低、动力不足的问题发生，大大延长了其使用寿命高，且振捣效果较较好。
