Through adopting above-mentioned technical scheme, the tuyere can blow out high-speed air current to the outside of drum sieve, and high-speed air current can be fallen by the jam clearance that the straw caused, effectively improves and prevents stifled effect.

The utility model is further configured to: the air outlet of the fan is also communicated with a winnowing blow-off nozzle which is fixed on the frame and positioned at one end of the cylindrical screen for discharging.

Through adopting above-mentioned technical scheme, the selection by winnowing mouthpiece can carry out the layering screening to the unhusked rice and the debris that flow in the drum sieve, guarantees that the unhusked rice can not fall into the debris export, avoids the waste of unhusked rice.

The utility model is further configured to: the inclination angle of the cylindrical screen is between 10 and 13 degrees.

By adopting the technical scheme, if the inclination angle of the cylindrical sieve is too large, the rice cannot enter the rice outlet through the screen of the cylindrical sieve in time, a large amount of rice can appear in the impurity outlet, and the rice waste is caused; if the inclination angle of the cylindrical screen is too small, the time for the sundries to flow out of the cylindrical screen is prolonged, and the screening efficiency is reduced. The screening efficiency of the rice can be improved on the premise that the inclination angle of the cylindrical screen is 10-13 degrees, so that the minimum waste amount of the rice can be ensured.

In conclusion, the beneficial technical effects of the utility model are as follows:

(1) the anti-blocking roller is used for timely cleaning sundries blocked in the sieve pores of the cylindrical sieve, so that the normal use of the cylindrical sieve is ensured, frequent cleaning by operators is not needed, and the cylindrical sieve has high reliability and convenient use;

(2) the utility model utilizes the comb tooth rods to separate the straw mixed in the paddy and utilizes the air nozzle to clean the straw blocked in the sieve pores of the cylindrical sieve, thereby effectively improving the separation effect of the straw and improving the anti-blocking capability.
