Hydraulic oscillating soil sampler

The utility model relates to a hydraulic oscillating soil sampler, belonging to the soil sampling machine for the pile holes of important engineering foundations for tall buildings, bridges, etc. The hydraulic oscillating soil sampler is mainly provided with a hydraulic power pack for jointly controlling a crank shaft to drive a heavy hammer to have high-frequency reciprocating movement and generate radical force, the soil sampler is then forced to propel mud layers with high power. A soil sampling shovel is then jointly controlled to sample soil, and a soil storing tank is jointly controlled to unload the soil after fully storing the soil. The utility model has the advantages of fully hydraulic drive, stable and reliable operation, no noise, multiple capabilities of sampling soft soil, hard soil, bottom mud, sandy soil, etc., stable hole quality of the sunk piles, and unexampled hole-shaping method that the acerbity hole-drilling method and the manual hole-digging method can not reach.
