The present invention discloses a push-swing combined wave generator, comprising a wave-generating fixing bracket, a servo motor, a driving wheel, a connecting rod, a first hydraulic cylinder, a second hydraulic cylinder, a first hydraulic cylinder push rod, a second hydraulic cylinder push rod, and a wave-generating plate. The sliding pins arranged in the wave-generating plate slide in the axial direction, and are switchable to connect either the first hydraulic cylinder push rod or the second hydraulic cylinder push rod with the wave-generating plate, and thus to render the push-swing combined wave generator to operate in respective locked state or unlocked state. The present invention integrates pushing and swinging, is capable of implementing horizontal pushing and swinging wave generating modes respectively, generating various wave types, and meeting requirements of various forms of wave generating.

A hydraulic vibration generation device is provided. The device includes a manifold member having an inner volume, a fluid inlet orifice and a fluid outlet orifice. The device further includes a vibration generating member having a channel grooved drive and an off-center weight, and bearing retaining plates. The inner volume receives the vibration generating member within the inner volume.
