[0024] The square neck width of the semi-circular head square neck bolt 3 matches the width of the locking square hole 22.

[0025] The positioning plate 25, the U-shaped clamping groove 24 and the L-shaped plate 26 are integrally bent and manufactured.

[0026] The semi-circular head square neck bolt 3 is a half-thread bolt, and an external thread is provided at the end.

[0027] In this embodiment, referring to the attached Figures 1-5 , the fixed clamping plate 2 is provided with a positioning protrusion 21, a locking square hole 22, a locking square hole 23 and a U-shaped clamping groove 24. The positioning protrusion 21 cooperates with the locking square hole 22. The positioning protrusion 21 is inserted into the upper edge of the locking square hole 22 in alignment. The positioning protrusion 21 does not contact the locking square hole 22. The positioning protrusion 21 is engaged with the locking square hole 22. The distance between the positioning protrusion 21 and the upper edge of the locking square hole 22 is greater than 1 mm and less than 2 mm. The length of the positioning protrusion 21 is less than the thickness of the fixed clamping plate 2.

[0028] The locking square hole 1-22 and the locking square hole 2-23 cooperate with the button head square neck bolt 3, the gasket 6 and the hexagon lock nut 5. The button head square neck bolt 3 sequentially passes through the locking square hole 1-22, the locking square hole 2-23, the connecting fixed sleeve 7 and the gasket 6, and is tightened by the hexagon lock nut 5 for locking. The hexagon lock nut 5, the connecting fixed sleeve 7 and the gasket 6 are arranged on the same side of the fixed clamping plate 2; the width of the locking square hole 1-22 fits the square neck size of the button head square neck bolt 3. The square neck of the button head square neck bolt 3 is inserted into the locking square hole 1-22. After the button head square neck bolt 3 and the hexagon lock nut 5 are tightened and fixed, the fixed clamping plate 2 is always fixed and will not move or rotate, ensuring the firm clamping of the fixed clamping plate 2.

[0029] The U-shaped card slot 24 cooperates with the driving shaft 1. The driving shaft 1 is a hollow shaft body. The driving shaft 1 is placed in the U-shaped card slot 24 and is tightened by the button head square neck bolt 3 and the hexagon lock nut 5. The U-shaped card slot 24 clamps the driving shaft 1 for fixation, determining the position of the fixed clamping plate 2 on the driving shaft 1, ensuring the fastening of the fixed clamping plate 2 on the driving shaft 1, thus ensuring the firm connection between the driven shaft 4 and the driving shaft 1 and ensuring the normal operation of the linkage mechanism.

[0030] The fixed clamping plate 2 cooperates with the button head square neck bolt 3, the hexagon lock nut 5, the gasket 6, the connecting fixed sleeve 7 and the driven shaft 4 for locking. The driven shaft 4 is composed of a driven shaft body 41 and a driven shaft connecting plate 42. The button head square neck bolt 3 sequentially passes through the locking square hole 1-22, the locking square hole 2-23, the connecting fixed sleeve 7 and the gasket 6 of the fixed clamping plate 2, and is tightened by the hexagon lock nut 5. The hexagon lock nut 5 presses the gasket 6 and the connecting fixed sleeve 7 to press the fixed clamping plate 2. The round hole on the driven shaft connecting plate 42 is sleeved on the connecting fixed sleeve 7. The diameter of the connecting fixed sleeve 7 is slightly smaller than the diameter of the round hole of the driven shaft connecting plate 42, and the length of the connecting fixed sleeve 7 is slightly larger than the thickness of the driven shaft connecting plate 42. When the hexagon lock nut 5 is tightened, the gasket 6 presses the connecting fixed sleeve 7 and does not press the driven shaft connecting plate 42. On the basis of the stable connection between the driven shaft 2 and the driving shaft 1, it is ensured that after the longitudinal position of the driven shaft 2 is locked, it can rotate with the lateral movement of the driving shaft 1.

[0031] The utility model designs a positioning protrusion on the fixed clamping plate 2. By measuring the distance between the positioning protrusion and the upper edge of the first locking square hole 22, it is determined whether the fixed clamping plate part is processed qualified. The distance between the positioning protrusion 21 and the upper edge of the first locking square hole 22 is greater than 1 mm and less than 2 mm, which is qualified, ensuring that the first locking square hole 22 and the second locking square hole 23 are aligned. By the positioning protrusion 21, it is ensured that all the fixed clamping plates 2 used in the corn harvester are qualified products, eliminating the factors of machine failure caused by unqualified fixed clamping plates 2 and ensuring the qualified rate of the fixed clamping plate 2 parts; the relative position of the fixed clamping plate 2 on the driving shaft 1 is fixed by locking the U-shaped card slot 24, ensuring the firm and stable connection between the driven shaft 4 and the driving shaft 1; the width of the first locking square hole 22 is fitted with the square neck size of the semi-circular head square neck bolt 3. After the semi-circular head square neck bolt 3 is tightened, it is ensured that the fixed clamping plate 2 is affected by the square neck of the semi-circular head square neck bolt 3 and cannot rotate, ensuring the stability of the locking of the fixed clamping plate 2.

[0032] In the production of the fixed clamping plate 2 parts of the utility model, through the cooperation of the positioning protrusion 21 and the first locking square hole 22, it is possible to quickly and efficiently check whether the production of the fixed clamping plate 2 is qualified, screen out unqualified parts in time, and make adjustments in time to avoid the use of unqualified parts. As an important component connecting the driving shaft 1 and the driven shaft 4, while the fixed clamping plate 2 locks the driving shaft 1 through the U-shaped card slot 24, the round hole of the driven shaft connecting plate 42 is sleeved on the connecting fixed sleeve 7, and the hexagonal locking nut 5 presses the gasket 6 and the connecting fixed sleeve 7, which are locked together with the fixed clamping plate 2 without squeezing the driven shaft connecting plate 42. When the driving shaft 1 and the driven shaft 4 are firmly connected, the driven shaft 4 can rotate with the lateral movement of the driving shaft 1, ensuring the normal operation of the ear picking device on the corn harvester.
