The invention relates to a hydraulic self-induced vibration subsoiler. The hydraulic self-induced vibration subsoiler is characterized by comprising a machine frame and a subsoiling device, wherein the subsoiling device is arranged at the bottom of the machine frame, the machine frame is composed of suspension pair plates, a front beam, a rear beam, an inclined traction rod, a cross beam, a cross traction rod, U-shaped groove fixing pieces and V-shaped locking pieces, and the subsoiling device is composed of shovel points, shovel wings and shovel handles. According to the hydraulic self-induced vibration subsoiler, the stretch and retraction amount of vibration springs is controlled and adjusted through hydraulic oil, the embedded depths of all subsoiling shovels are effectively adjusted, in this way, the tilling depth consistency is guaranteed during subsoiling, and the overall vibration which causes discomfort of a driver of a tractor and the like and is generated due to inconsistency of shake of mechanisms of the subsoiler is reduced; compared with a non-vibration subsoiler and a one-way vibration subsoiler under the same condition, during work, the traction resistance is remarkably reduced; to sum up, the hydraulic self-induced vibration subsoiler can reduce resistance and save energy and is good in operation effect and high in adaptability.
