The invention discloses a ginger soil-screening device with double vibrating screens. The device comprises a vibration box body, wherein vibration support legs are arranged under the vibration box body; a transmission plate is arranged at the bottom of the vibration box body; a vibration motor is mounted on the transmission plate; a mounting frame is arranged in the vibration box body; a vibration screen plate is mounted in the mounting frame; one end of the vibration box body is connected with a feeding port; the vibration box body is away from one end of the feeding port; a first discharging port is formed in the upper part of the vibration screen plate; and the vibration box body is positioned under the first discharging port, and a second discharging port is formed in the vibration box body. According to the ginger soil-screening device provided by the invention, when gingers are vibrated on the vibration screen plate and soils are screened out, a vibration hair brush positioned above the vibration screen plate vibrates forwards and backwards along the surface of the vibration screen plate, so that the hair brush can clean the soils on the surfaces of the gingers; due to the arrangement of the double vibration screens, the soil screening efficiency of the device to the gingers is improved, and a cleaning work of the gingers can be completed if the soils are screened out once, thereby improving the working efficiency and reducing the labor quantity of workers.
