Background
The threshing machine is harvesting machine, which is a machine capable of separating crop grains from stalks, and mainly is harvesting machine for grain crops. The types of the threshing machine are different according to different grain objects. Such as "thresher" for rice threshing, so-called "corn thresher" for corn threshing, etc. The thresher is commonly called as a thresher, and is the most common rice threshing machine. It is necessary to separate rice grains from stalks by such a machine after harvesting the rice. The rice thresher is divided into two types, one type is driven by manpower and is called a 'manual rice thresher', which is a semi-mechanized tool, and the other type is driven by power and is called a 'power rice thresher'. The rice thresher greatly reduces the labor intensity of harvesting rice and improves the agricultural productivity.
The existing corn thresher adopts manual bare hands to push corn cobs into a threshing cylinder of the thresher. In the pushing mode, a worker needs to overcome the blocking force from the threshing cylinder to push the corn cobs, and the corn cobs are held and prevented from rotating, so that the labor intensity of the worker is high.

Example 8
The present embodiment further describes the structure of the holder 19.
As shown in fig. 1 to 12, in the present invention, a secondary cutter ring 25 is disposed in the cutter holder barrel 19, the axis of the secondary cutter ring 25 coincides with the axis of the cutter holder barrel 19, the outer wall of the secondary cutter ring is connected with the inner wall of the cutter holder barrel 19, a plurality of cutter teeth 26 are uniformly disposed on the top of the secondary cutter ring 25 along the circumferential direction, the top ends of the cutter teeth 26 are curved toward the axis of the cutter holder barrel 19, and the distance between the top ends of the cutter teeth 26 and the axis of the cutter holder barrel 19 is smaller than the distance between the top ends of the primary cutter ring 23 and the axis of the cutter holder barrel 19.
Corn is of different sizes from species to species. And corn cobs with smaller outer diameter can only be contacted with the threshing cutter along a certain size deviating from the axis of the threshing cylinder during threshing. And when one side of the threshing knife contacts with corn cobs, damage can be generated at the fixed part of the threshing cylinder due to uneven stress. In the present invention, therefore, it is preferable to provide the sub-cutter ring 25 in the cutter holder barrel 19, and the minimum inner diameter of the sub-cutter ring 25 is larger than the outer diameter of the conventional corn cob cores so that the conventional corn cob cores can pass through the sub-cutter ring 25 after being threshed by the threshing cutter.
When corn cobs with smaller threshing outer diameter pass through the main cutter ring 23 and then are threshed through the auxiliary cutter ring 25. The secondary knife ring 25 can be connected with the knife holder barrel 19 by wire, welded, clamped and the like.
Example 9
