The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

A corn thresher is shown in figure 1 and comprises a feeding pipe 1, a material pushing device 2 and a threshing device 3.

The feeding pipe 1 is horizontally erected on the ground through a support. The feeding pipe 1 is provided with a feeding port 11 on the cylindrical surface at the upstream end part so that the corn can be put into the feeding pipe 1. The pushing device 2 comprises a pushing block 21 and a pushing driver 22, the pushing block 21 is located on one side of the feeding port 11 and is driven by the pushing driver 22 to be inserted into the feeding pipe 1 along the axis of the feeding pipe 1, and a hydraulic cylinder serving as the pushing driver 22 repeatedly and slowly stretches out and draws back to ensure the threshing rate.

The threshing device 3 comprises a drum 31 and a threshing drive 32. The roller 31 is rotatably connected to the ground through a bearing and a bearing seat, and the roller 31 is coaxially arranged with the feeding pipe 1 and is used as a threshing driving device 32 to drive the roller 31 to rotate through a belt.

As shown in fig. 2, one end of the roller 31 is provided with a plurality of circles of movable spike teeth 4. The movable spike 4 includes, in order, a crown portion 41, a shank portion 42 and a spike tip portion 43. One end of the roller 31 is provided with a plurality of through holes along the circumferential array on the cylindrical surface, and each through hole is provided with a movable spike tooth 4. The nail body part 42 is inserted into the through hole and penetrates through the wall surface of the roller 31, and the diameter of the top cap part 41 is larger than that of the through hole, so that the length of the movable spike teeth 4 extending into the inner wall of the roller 31 is controlled, the movable spike teeth 4 slide along the radial direction of the roller 31, and the tail ends of the movable spike teeth are inserted into the inner cavity of the roller 31.

The outer wall of the roller 31 is provided with a mounting platform 5 around each through hole, and the mounting platform 5 is in threaded connection with a mounting cover 6 covering the through holes. The spring 7 is interposed between the mounting cover 6 and the top cap 41, and the spring 7 as an elastic member causes the movable pins 4 to always tend to slide toward the inside of the drum 31.
