Preferably, as shown in fig. 1, a blanking device 20 is further connected below the primary screening machine 2, and referring to fig. 6-7 together, the blanking device 20 includes a rectangular receiving bin 21, a cylindrical impeller member 22 is installed in the receiving bin 21, front and back end faces of the impeller member 22 are in smooth fit with two inner surfaces of the receiving bin 21, the rectangular impeller of the impeller member 22 can be smoothly connected with an inner surface of the receiving bin 21 when rotating, so that when rims of two adjacent impellers are simultaneously in contact with the inner surface of the same receiving bin 21, the two adjacent impellers and the mandrels of the impeller member 22 and the inner surface of the receiving bin 21 together enclose a wedge-shaped accommodating cavity, and the accommodating cavity is used for accommodating a rated amount of grains. Meanwhile, a trapezoidal material collecting bin 23 is connected below the material collecting bin 21, a small port of the material collecting bin 23 faces downwards and is in butt joint with a flat rectangular material discharging bin 24, and a purging device used for purging dust in grains is arranged on one side below the material discharging bin 24 so as to horizontally purge impurities such as dust in falling grains. The volume that holds the chamber equals go out the volume of feed bin 24, and the platykurtic that goes out feed bin 24 must make the grain in the feed bin 24 can freely scatter away and not jam in a feed bin 24, above to go out feed bin 24 and hold the structure of chamber and prescribe a limit to, it is comparatively important, if the platykurtic undersize that goes out feed bin 24, then one holds the once grain that falls in chamber and gathers in feed bin under most likely, cause the jam, unable normal continuation whereabouts, and if too big, the grain curtain that the grain whereabouts formed is crossed the back, then be unfavorable for follow-up air-blowing screening. When the material dropping device 20 is used, the screened grains enter the material receiving bin 21, when the impeller part 22 rotates, the grains are transferred to the material collecting bin 23 below the impeller part 22 through the containing cavity, all the grains can quickly and intensively fall to the bottom of the material collecting bin 23 and enter the material discharging bin 24 in view of the trapezoid structure of the material collecting bin 23, the material discharging bin 24 is a cavity matched with the containing cavity and is of a flat nozzle structure, the thickness of the material discharging bin can enable the grains falling into one containing cavity to be dispersed and filled in the material discharging bin 24, so that the grains falling off after one time of transferring in one containing cavity can be fully and uniformly scattered, the grains cannot be stuck due to excessive grains and cannot fall too intensively to form a conical volcanic grain pile, the grains are excessively gathered to be unfavorable for subsequent automatic collapse and transportation, and the subsequent grains are cleaned by wind, and meanwhile, the subsequent grains are cleaned of dust impurities by wind, the dust is more thoroughly floated out.

As a further preferred embodiment, in order to monitor that the impeller member 22 is always submerged in the grain, and to ensure that each of the above-mentioned containing cavities formed by rotation is filled with grain as much as possible, so as to perfectly match the grain falling from the bin 24, as shown in fig. 6, in this embodiment, an inverted conical cover 25 is very skillfully butted on the upper end of the receiving bin 21, and a sensor 26 is also arranged in the middle of the conical cover 25 in a suspended manner, so that the conical cover 25 is inverted with its large end facing downward, mainly in order to ensure that no excessive grain layer is accumulated on the inner wall of the conical cover 25, so as to confirm that the periphery of the sensor 26 is actually in a blank state, that is, there is no grain pressure in the surrounding horizontal plane, which indicates that the grain has actually fallen to the interface where the impeller member 22 is about to be exposed, and that the full transfer of the containing cavities can be ensured by supplementing grain; however, if a rectangular or cylindrical bin is directly used, it is inevitable that a certain amount of grain will be accumulated around the inner wall of the bin, but the middle of the bin is blank (as shown in fig. 10), which leads to inaccurate information of the grain falling interface detected by the sensor 26. In use, the sensor 26 can detect whether the conical cover 25 is filled with grain, and if no grain is detected, a signal is sent to the controller, so that the controller controls the impeller member 22 to stop rotating to replenish enough grain.
