The invention discloses a hydraulic motor controlled eccentric vibration device for picking medlar, which comprises a shell, wherein the hydraulic motor is fixedly connected to the middle position of the inner top wall of the shell, an output shaft of the hydraulic motor is fixedly connected with a driving wheel, and a first driven wheel and a second driven wheel are respectively arranged on two sides of the driving wheel. According to the invention, the transmission rod and the oscillating rod are driven to oscillate back and forth through the centrifugal action generated by the rotation of the first eccentric wheel and the second eccentric wheel, so that the two connecting rods are driven to rapidly reciprocate in the oscillating groove, and meanwhile, when the two connecting rods reciprocate, the two connecting rods are prevented from violently colliding with the oscillating groove due to the buffering action of the first buffer spring between the inner groove and the buffer stop block and the second buffer spring between the buffer cylinder and the piston rod, so that the service life of the device is prolonged, the Chinese wolfberry falling rod is driven to start falling through the two connecting rods, the damage of high-speed rotation to Chinese wolfberry is avoided, and the Chinese wolfberry processing efficiency is improved. |
