Preferably, the central axis of the central axis for containing grain cylinder, the central axis of annular block set and threshing cutter head exists
In same vertical straight line.
Preferably, the outer diameter of the flow guide sleeve lower end is equal to the diameter of annular block set outer wall.
Preferably, the side end face of switch-plate two sides side plate is arc-shaped, the circle of switch-plate side side plate side end face
Arc radius is equal to the radius for containing grain cylinder inner wall;The arc radius of switch-plate other side side plate side end face is equal to annular block set outer wall
Radius.
Preferably, the length of the switch-plate is greater than the height for containing annular block set on grain cylinder.
Preferably, the diameter of the magnetic steel sleeve outer wall is less than the diameter of annular hub interior wall, the threshing cutter head, Sheng Li
Cylinder and switch-plate are all made of non magnetic material.
Several installation trunnions are fixed on the outer wall for containing grain cylinder, installs and forms mounting hole on trunnion.
The beneficial effects of the present invention are: it uses revolving threshing cutter head, can improve threshing quality, is able to achieve its rotation
Rotatable threshing cutter head can also provide power for switch-plate, and the output of corn particle is realized using switch-plate.

Specific embodiment:
Embodiment: as shown in FIGS. 1 and 2, the threshing structure on a kind of rotary corn threshing device, including cylindrical Sheng
Grain cylinder 1, the lower end for containing grain cylinder 1 form relief hole 11, contain the ring for forming in the inside bottom surface of grain cylinder 1 and being connected with relief hole 11
Shape block set 12, the upside of annular block set 12 are equipped with the threshing cutter head 3 of annular, and the upper end of threshing cutter head 3 forms a threshing tooth 31,
The downside of threshing cutter head 3 forms the flow guide sleeve 32 of cone, and what the lower end of flow guide sleeve 32 formed oriented recess is nested with 33, interior
Nesting 33 is plugged in annular block set 12, and the lower end of flow guide sleeve 32 is resisted against on the upper surface of annular block set 12, described to be nested with
