It includes a threshing structure and a threshing bracket. The threshing mechanism is fixedly installed at the upper end of the threshing bracket. Three threshing bins are arranged in the threshing mechanism at a certain angle in sequence, and a threshing shaft is arranged in each of the threshing bins. In the above-mentioned prior art, through the threshing shaft in the threshing bin, the corn cob ears are pushed by the spiral blades and threshed under the rubbing of the threshing teeth. The rubbing linear speed is low and the impact force is small, so the crushing loss is small, the threshing efficiency is high, the yield of crops is increased, and the waste of corn kernels is avoided.

[0063] By the reciprocating movement of the piston shaft one 11 along the piston cylinder one 13, the external air is drawn into the inner cavity of the piston cylinder one 13 from the one-way intake pipe 14, and then the air in the inner cavity of the piston cylinder one 13 is pushed into the compression assembly from the one-way exhaust pipe 15 for compression.

[0066] The compression cylinder 16 is installed in the protective housing 2, the first elastic member 17 is installed in the compression cylinder 16, and the other end thereof is connected to the compression plate 18.

[0067] Example 4, as Figures 2 - 6 and Figures 9 - 11 shown, an intelligent corn cob processing device for a corn harvester proposed by the present invention. Compared with Example 3, in this embodiment, the switch mechanism includes a second pipe 34, a third piston cylinder 36, a second spring 37, a second piston shaft 38, a switch plate 39, a third round pipe 40, and a trigger assembly;

[0068] The second pipe 34 communicates with the second piston cylinder 21, and the other end thereof is connected to the third piston cylinder 36; the second spring 37 is installed in the third piston cylinder 36, and the other end thereof is connected to the second piston shaft 38.

[0070] The third spring 41 is installed in the collection assembly, and the other end thereof is connected to the inclined panel 42.

There are two second cylinders 35 in total, and the two second cylinders 35 communicate with the second pipe 34 and the third round pipe 40 respectively; the T-shaped plate 43 is connected to the third column 44 and the fourth column 45. The third column 44 is located at the connection of the second pipe 34 and the second cylinder 35, and the fourth column 45 is located at one end of the connection of the third round pipe 40 and the second cylinder 35 away from the third round pipe 40; in the initial state, the third column 44 blocks the second pipe 34, and air cannot enter the third piston cylinder 36 from the second pipe 34. The fourth column 45 does not block the third round pipe 40, and the third piston cylinder 36 communicates with the outside through the third round pipe 40. When the inclined panel 42 is pressed, the third column 44 and the fourth column 45 move in the direction of the T-shaped plate 43. At this time, the third column 44 does not block the second pipe 34, and air enters the third piston cylinder 36 from the second pipe 34, and the fourth column 45 blocks the third round pipe 40.

[0071] In the initial state, the limiting plate 49 is in contact with the movable shell 24, so as to limit the limiting plate 49 through the movable shell 24, and further limit the inclined panel 42, thereby preventing the situation that the inclined panel 42 is squeezed when the crushed material is compressed.

[0072] When the extrusion plate 32 compresses the crushed material, it will push the limiting plate 49 in the direction of the elastic member four 48. When the limiting plate 49 is pushed into the inner cavity of the inclined panel 42, the extrusion plate 32 immediately pushes the inclined panel 42 to move.

[0073] The elastic member one 17, the elastic member two 23, the elastic member three 28 and the elastic member four 48 are all composed of a telescopic rod and a spring four. The spring four is sleeved on the outer periphery of the telescopic rod.

[0074] In summary, in the present invention, the threshing equipment body 1 is installed in the corn harvester. After the corn is threshed, the corn cob shaft enters the inner cavity of the housing 3. Then, the driving device 4 is started to drive the transmission member 5 to operate. The transmission member 5 drives the crushing roller 6 to rotate, and the corn cob shaft is crushed. After crushing, the corn cob shaft enters the inner cavity of the movable shell 24.

[0075] After the rotation of the crushing roller 6 is decelerated by the reducer 7, it drives the turntable 8 to rotate at a reduced speed. The turntable 8 drives the rotating rod 9 to rotate. The piston shaft one 11 is limited by the guide rod 12, so that the rotating rod 9 drives the piston shaft one 11 to reciprocate along the axis direction of the piston cylinder one 13. When the piston shaft one 11 moves in the direction of the guide rod 12, the external air is drawn into the inner cavity of the piston cylinder one 13 from the one-way intake pipe 14. When the piston shaft one 11 moves in the direction of the one-way outlet pipe 15, the air is squeezed into the inner cavity of the compression cylinder 16 through the one-way outlet pipe 15. In the inner cavity of the compression cylinder 16, the compressed air drives the compression plate 18 to compress the air under the pressure of the elastic member one 17.

[0076] The corn cob shaft is collected in the inner cavity of the movable shell 24, and the weight of the corn cob shaft will drive the movable shell 24 to descend. When the movable shell 24 descends, it drives the lifting rod 25 to descend along the T-shaped rod 26. When the inner cavity of the movable shell 24 is filled with crushed material, the movable shell 24 descends to the lowest position, and then drives the T-shaped rod 26 to descend through the lifting rod 25. When the T-shaped rod 26 descends, it drives the column one 27 and the column two 29 to descend.

[0077] When the column one 27 descends away from the connection between the cylinder one 20 and the pipe one 19, the column two 29 descends to block the rectangular hole of the cylinder three 46. At this time, the compressed air in the inner cavity of the compression cylinder 16 enters the inner cavity of the piston cylinder two 21 along the pipe one 19, thereby pushing the piston shaft three 47 to move in the direction of the spring one 30. Then, the piston shaft three 47 drives the lifting plate 31, the extrusion plate 32 and the fixing plate 33 to extrude the crushed material in the inner cavity of the movable shell 24, and the crushed material in the inner cavity of the movable shell 24 is limited by the baffle above the fixing plate 33.

[0078] When the extrusion plate 32 moves into contact with the limit plate 49, it will push the limit plate 49 to move in the direction of the elastic member four 48. After the limit plate 49 completely enters the inner cavity of the inclined panel 42, the inclined panel 42 loses the limitation of the limit plate 49. Subsequently, the extrusion plate 32 will push the inclined panel 42 to move in the direction of the spring three 41, thereby causing the inclined panel 42 to drive the T-shaped plate 43 away from the cylinder two 35. Subsequently, the column three 44 leaves the connection between the pipe two 34 and the cylinder two 35, enabling the compressed air that enters the inner cavity of the piston cylinder two 21 to enter the inner cavity of the piston cylinder three 36 along with the pipe two 34. At the same time, the column four 45 blocks the circular pipe three 40, preventing the air in the inner cavity of the piston cylinder three 36 from leaking out.

[0079] Then, the air that enters the inner cavity of the piston cylinder three 36 will push the piston shaft two 38 in the direction of the spring two 37, thereby driving the switch plate 39 to move in the direction of the piston cylinder three 36, and then causing the crushed material blocks in the inner cavity of the movable shell 24 to fall into the field. Thus, after ensuring that the crushed material is compacted into blocks, the crushed material blocks are discharged, ensuring the stability of the formed blocks and facilitating the recycling by the staff.

[0080] After the crushed material in the inner cavity of the movable shell 24 is discharged, the elastic member two 23 drives the fixed shell 22 and the movable shell 24 to contract. Subsequently, the spring three 41 drives the inclined panel 42 to reset. The column four 45 leaves the connection between the circular pipe three 40 and the cylinder two 35, and the column three 44 moves to the connection between the pipe two 34 and the cylinder two 35, enabling the air in the inner cavity of the piston cylinder three 36 to be discharged from the circular pipe three 40 and blocking the pipe two 34.

[0081] The lifting rod 25 rises and separates from the T-shaped rod 26. Driven by the elasticity of the elastic member three 28, the column two 29 and the column one 27 rise. The column one 27 resets to the connection between the pipe one 19 and the cylinder one 20, blocking the pipe one 19.
