In the process of discharging, the function of screening the grains can be realized again, effectively ensuring the screening and impurity removal efficiency and effect of the device when in use.

[0006] Technical effects and advantages of the present invention: 1. In the present invention, grains are introduced into the elastic arc plate through the feed plate, and the second drive motor is used to start the driving support cylinder to rotate. When the support cylinder rotates, the elastic sleeve and a plurality of elastic threshing teeth are driven to rotate simultaneously. When the elastic threshing teeth rotate, the grains on the elastic arc plate are pressurized, so that the grains fall off the straws, and the grains can be discharged through the screening holes, so that threshing and screening are carried out simultaneously, which is easy for subsequent impurity removal; 2. The grains of the present invention are discharged through the screening holes and blocked by the material discharging inclined plate, and then fall into the screening plate, and are screened by the second screening rods and the first screening rods, thereby realizing the function of screening the defective products, and the straws can be sent out through the torsion force of the elastic threshing teeth when they rotate; 3. When the grains of the present invention are discharged through the screening holes, the first pulley drives the rotating shaft to rotate when the supporting cylinder rotates, and then the multiple impellers rotate, so as to realize the function of extracting the airflow, so that the defective products and dust impurities can be extracted into the impurity removal box through the frame opening, so as to realize the function of removing impurities; 4. The present invention drives the reinforcing shaft and the extension seat to rotate through the first driving motor, drives the multiple feeding rods, feeding arc blocks and stop blocks to rotate, and performs the function of feeding the grains screened on the second screening rod. The feeding rod rotates one circle to transport the grains into the screening shell, and the conveying auger rotates to discharge the grains. In the process of discharging, the function of screening the grains can be realized again, effectively ensuring the screening and impurity removal efficiency and effect of the device when in use; 5. In the present invention, when the feeding rod rotates, the feeding arc block can also contact with the elastic arc plate, so that the elastic arc plate is deformed. When the elastic arc plate is not in contact with the feeding arc block, the elastic arc plate resets itself elastically to realize the function of vibrating and screening the grains on the elastic arc plate. When the elastic arc plate moves upward, the grains are squeezed against the elastic sleeve to improve the efficiency and effect of grain threshing and screening.

[0007] To sum up, the overall design is simple and the structure is reasonable. Through the corresponding coordinated use of various structures, the elastic threshing teeth will pressurize the grains on the elastic arc plate when rotating, so that the grains fall off the straw, and the grains can be discharged through the screening holes, so that threshing and screening can be carried out simultaneously, which is easy for subsequent impurity removal. Multiple second screening rods and the first screening rod are screened to realize the function of screening defective products, and the straw can be sent out through the torque when the elastic threshing teeth rotate. Through the rotation of multiple impellers, the airflow is extracted, so that the defective products and dust impurities can be extracted into the impurity removal box through the frame opening, so as to realize the function of removing impurities. The grains are transported to the screening shell by rotating the feeding rod for one circle, and are discharged by rotating the conveying auger. In the process of discharging, the function of screening the grains can be realized again, which effectively ensures the screening and impurity removal efficiency and effect of the device when in use, eliminates the cumbersome steps of the original threshing, and realizes the function of one machine with multiple uses.

The combined equipment for screening and removing impurities from grains for brewing according to claim 1 is characterized in that: A conveying auger (303) located in the machine case (101) is arranged at the bottom of the sieving plate (203), and a sieving shell (304) installed in the machine case (101) is arranged on the outside of the conveying auger (303).

8. The combined equipment for screening and removing impurities from grains for brewing wine according to claim 7 is characterized in that: A debris removal box (305) is provided on one side of the surface of the screening shell (304), a rotating shaft (306) is provided inside the debris removal box (305), a plurality of impellers (307) are distributed on the outside of the rotating shaft (306) and along the circumference of the axis point of the rotating shaft (306), and frame openings (308) are provided on both sides of the surface of the debris removal box (305).

9. The combined equipment for screening and removing impurities from grains for brewing wine according to claim 8, characterized in that: A first pulley (309) is provided at one end of the rotating shaft (306) and located outside the dust removal box (305), a second pulley (310) is provided at one end of the conveying auger (303), and the second pulley (310) and the first pulley (309) are both sleeved on one end of the support cylinder (3), and a second drive motor (311) for driving the support cylinder (3) to rotate is provided on the outside of the protective cover (102).

10. An operating method, using the combined equipment for screening and removing impurities from grains for brewing wine according to any one of claims 1 to 9, characterized in that: The method comprises the following steps, Step 1: The grains are introduced into the elastic arc plate (201) through the feed plate (2), and the support cylinder (3) drives the elastic threshing teeth (302) to rotate when rotating to pressurize the grains on the elastic arc plate (201), so that the grains fall off the straws and can be discharged through the sieve holes (202); Step 2: the grains are discharged through the screening holes (202), blocked by the discharge inclined plate (214), and then fall into the screening plate (203), where they are screened by the plurality of second screening bars (213) and the first screening bar (211), while the straws are sent out by the torsion force of the elastic threshing teeth (302) during rotation; Step three, when the grains are discharged through the screening holes (202), the support cylinder (3) rotates via the first pulley (309) to drive the rotating shaft (306) to rotate, thereby causing the plurality of impellers (307) to rotate, so that the defective grains and dust impurities can be extracted into the impurity removal box (305) through the frame opening (308); Step 4: The grains screened on the second screening bar (213) are screened by rotating the plurality of feeding rods (207), the feeding arc block (208) and the stopper (209). The feeding rod (207) rotates one circle to transport the grains into the screening shell (304), and the grains are discharged by rotating the conveying auger (303).
