An object of the utility model is to provide a winnowing equipment is used in grain screening, its is rational in infrastructure, convenient operation, and the impurity separation is effectual, and the practicality is strong.
In order to achieve the purpose, the technical scheme of the utility model is to design a winnowing device for screening grains, which comprises a separating cylinder, a feeding mechanism and a discharging mechanism;
the top of the separating cylinder is provided with a feeding hole, the bottom of the separating cylinder is provided with a discharging hole, the side wall of the separating cylinder is provided with a first opening and a second opening, the first opening and the second opening are oppositely arranged, a blower is arranged in the first opening, and the outer side of the separating cylinder is connected with a collecting bin communicated with the second opening;
the feeding mechanism comprises a first feeding conveying belt and a second feeding conveying belt, and the output end of the first feeding conveying belt and the output end of the second feeding conveying belt are both positioned above the feeding hole;
the blanking mechanism comprises a blanking conveying belt, and the blanking conveying belt is located below the discharge port. By adopting the scheme, the grains to be processed are conveyed to the upper part of the separating cylinder by the first feeding conveyer belt and the second feeding conveyer belt, and the grains are put into the separating cylinder through the feeding hole; through starting the hair-dryer operation, blow by the continuous grain of whereabouts in-process of hair-dryer to blow in the light impurity in the grain and fall to collecting the storehouse after the second opening, in order to reach the effect of selection by winnowing edulcoration, the grain of accomplishing the clearance falls to the unloading conveyer belt through the discharge gate on, and is transported to the appointed place by the unloading conveyer belt.
Preferably, the inside of the separation cylinder is provided with a first filter plate, and the first filter plate is positioned above the blower. Through adopting above-mentioned scheme, impurity such as the great stone of granule is filtered by first filter.
Preferably, the inside of the separation cylinder is provided with a second filter plate, and the second filter plate is positioned between the first filter plate and the blower. Through adopting above-mentioned scheme, impurity such as the stone that is less with the second filter filtering granule.
Preferably, the first filter plate is of an inverted V-shaped structure. Through adopting above-mentioned scheme, be favorable to making grain through the even scattering to the second filter of first filter.
Preferably, the first filter plate is uniformly provided with first filter holes, the second filter plate is uniformly provided with second filter holes, and the aperture of the first filter holes is larger than that of the second filter holes.
The utility model has the advantages and the beneficial effects that: the utility model provides a winnowing equipment is used in grain screening which is rational in infrastructure, convenient operation, and impurity separation is effectual, and the practicality is strong.
