Portable drop hammer vibration source device for surface wave exploration

The invention discloses a portable drop hammer vibration source device for surface wave exploration, which comprises a heavy hammer and a vibration source plate, and further comprises a vertical rod, a locking mechanism and an elastic component, the heavy hammer and the vertical rod form a pair of moving pairs; the vibration source plate is arranged at the lower end of the vertical rod; the locking mechanism is arranged on the upper portion of the vertical rod. The other end of the elastic component is fixedly connected with the heavy hammer; a connecting piece is arranged on the heavy hammer and can be combined and fixed with the locking mechanism; during use, the heavy hammer is connected with the locking mechanism through the connecting piece, the connection between the locking mechanism and the connecting piece is released, the heavy hammer falls down along the vertical rod and collides with the surface of the vibration source plate, the elastic assembly can increase the falling kinetic energy of the heav
