Full-automatic impurity removal device for grain samples to be detected

Abstract

The utility model discloses a full-automatic impurity removal device for grain samples to be detected. The full-automatic impurity removal device comprises a machine body, an impurity removal bin is arranged in the machine body, a classification bin is fixedly installed at the lower end of the impurity removal bin, a first sieve plate is movably installed in the impurity removal bin, and the lower end of the first sieve plate is movably connected with a second sieve plate. According to the full-automatic impurity removing machine, when the full-automatic impurity removing machine is used, the impurity removing bin is arranged in the machine, leaked grains are screened through the internal screen cloth, the vibrator is installed at the lower end of the screen cloth, the first screen cloth cleans dust, light and small impurities in the grains, and the draught fan on one side discharges the vibrated impurities outwards; grain samples and other impurities leak down to the second screen at the lower end, the second screen vibrates large impurities in the grains, due to the fact that the impurities are large in size and cannot leak down, the impurities move to the lower leakage opening in one side along with vibration to be discharged, full-automatic impurity removal is conducted through the machine, the burden of manual operation is reduced, and the working efficiency is improved.
