The covers are axially arranged and the first cover is adjacent to the transverse threshing cylinder and concave. The first cover is provided with at least five spiral vanes. The first vane has an angle of inclination to the transverse axis of approximately forty-five degrees; the second, third and fourth vanes have an angle of inclination of approximately thirty degrees; and the fifth vane has an angle of inclination of approximately twenty-five degrees. In small grains, such as rice, the second and third covers each have at least four vanes all with an angle of inclination of approximately twenty degrees. In corn, the second and third covers each have at least four vanes all with an angle of inclination of approximately ten degrees. The second and third covers are designed to be interchangeable depending on crop.
