The inner cylinder body is of a metal net structure, and a spiral feeding bulge is arranged on the outer wall of the inner cylinder body; the purpose of this is: because only one side of the sunflower has seeds, the inner cylinder body with the metal net structure can thresh the surface with the seeds by using the inner cylinder body under the condition that the side with the seeds faces the main shaft, and when the side with the seeds faces away from the main shaft, the sunflower seeds are threshed by using the arc net, so that the orientation problem of the sunflower in the feeding process does not need to be considered; the spiral feeding bulge is arranged to facilitate quick discharge of the threshed sunflower discs, so that the working efficiency is improved.

A gap is reserved between the inner cylinder and the outer cylinder, at least two arc-shaped nets are arranged in the gap, and the arc-shaped nets are installed on the inner wall of the outer cylinder through elastic connecting pieces; the purpose of this is: because the arc net is the wire netting, can be better rub the sunflower when threshing, improve the effect of threshing, set up elastic connecting piece for make the clearance between arc net and the interior barrel adjustable to the work of threshing is carried out to the sunflower dish that adapts to different thickness.

The two ends of the inner barrel are respectively provided with a connecting frame, the central position of the connecting frame is connected with a main shaft arranged at the center of the inner barrel, one end of the main shaft extends to the outside of the outer barrel, the end part of the main shaft is connected with a motor, and the motor is fixedly arranged on the outer wall of the outer barrel; the purpose of this is: the motor is used for providing kinetic energy for the rotation of the inner cylinder body, and the working efficiency is improved.

The utility model has the advantages that: the utility model has the advantages of simple structure and reasonable design, convenient to use can be avoiding causing under the broken prerequisite of sunflower dish, threshes the work to the sunflower, and it is effectual to thresh, is favorable to improving work efficiency and the operating mass with threshing of sunflower.
