The purpose of this utility model is to overcome the deficiencies in the prior art, and the bitubular that a kind of adaptability is strong, fault rate is low, production efficiency is high rice-wheat thresher is provided.

The utility model is achieved in that

It has a cabinet, on the top of cabinet master rotor and auxiliary cylinder is housed, and cover is housed respectively at master rotor with above the auxiliary cylinder, and screen cloth is housed respectively below; The material guide plate is equipped with in cover inboard at master rotor, and several dividing plates are housed on the screen cloth below master rotor; Slide plate is housed respectively below master rotor and auxiliary cylinder, the secondary screen cloth also is housed on the slide plate below master rotor, blower fan and auger are housed below slide plate; End at auxiliary cylinder is equipped with fans, so that foreign material are discharged; On the axle head of auxiliary cylinder one side, eccentric wheel is housed, drive link is housed on the eccentric wheel, a vibration fork is housed respectively in the both sides of cabinet, described drive link and a vibration fork are hinged, the vibration that eccentric wheel is produced passes to the vibration fork, a vibrating arm respectively is equipped with in top and bottom at the vibration fork, and two vibrating arms join with secondary screen cloth and slide plate respectively; Feed end at master rotor also is equipped with chain type clamping feeding mechanism.

The utility model compared with prior art has following advantage:

1, adaptability is strong, regardless of the wet degree of doing of rice wheat, all can carry out normal threshing, and less demanding to the feeding of material, no matter enter the material thickness in the machine, can both handle, and stable, easy and simple to handle.

2, on the screen cloth of master rotor, dividing plate is installed; reduced the friction of material to screen cloth; improved the service life of screen cloth; and cancelled the threshing cutter, both simplified interior, also reduced the wearing and tearing of material the drum threshing tooth; reduced the fault rate of equipment operation; reduced maintenance number of times and downtime, thereby improved production efficiency, more than the twice of output for existing chain type bitubular rice-wheat thresher.

3, the material guide plate is housed on the cover of master rotor, had both improved the mechanical strength of cover, avoided parts to be damaged, reduced material again, increased the time of threshing, thereby improved filter effect with the speed that cylinder rotates by the bulk foreign material.
