[0025] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0026] Example: Figure 1 and 2As shown, the eccentric sleeve positioning mechanism of the transmission box of this embodiment includes a transmission box 1, a frame 2 and an eccentric sleeve 7, and lower connecting seats 11 are respectively provided on both sides of the lower end of the transmission box 1, and an upper connecting seat 12 is provided at one end of the upper part of the transmission box 1. The lower connecting seat 11 and the frame 2 are rotatably assembled through a horizontally arranged lower support shaft 3, and a horizontal positioning mechanism 4 connected to the lower connecting seat 11 is provided on the frame 2. The eccentric sleeve 7 horizontally penetrates the upper connecting seat 12 and is rotatably connected. An upper positioning pin 5 rotatably assembled with the frame 2 is horizontally penetrated in the inner hole of the eccentric sleeve 7, and an angle adjustment and locking mechanism 6 connected to the end of the eccentric sleeve 7 is provided on the frame 2, and the lower support shaft 3 is arranged parallel to the upper positioning pin 5.

[0027] During the installation process, the lower connecting seat 11 is rotated and assembled with the frame 2, and the horizontal positioning mechanism 4 is used to perform horizontal positioning (that is, the axial positioning of the lower support shaft 3). The upper connecting seat 12 is rotatably connected with the frame 2 through the upper positioning pin 5 passing through the eccentric sleeve 7. During the assembly process, the eccentric sleeve 7 can be torsionally adjusted through the angle adjustment and locking mechanism 6. Since the outer circle and the inner hole of the eccentric sleeve 7 are not concentric, during the rotation of the eccentric sleeve 7, the upper connecting seat 12 does not move (that is, the axis of the outer circle of the eccentric sleeve 7 remains unchanged), and a certain deflection displacement occurs between the upper positioning pin 5 and the frame 2, which improves the defects caused by the forced installation of the existing transmission box and the frame. The overall structural design is simple and reasonable, which effectively solves the problem that it is difficult to ensure the installation position of the large baler, causing installation difficulties, or affecting its normal operation after forced installation.

[0028] As a preferred embodiment, Figure 3 As shown, the frame 2 is provided with a first mounting plate 21 corresponding to the lower connecting seat 11 one by one, the lower supporting shaft 3 passes through the first through hole adapted on the lower connecting seat 11 and the first assembly hole on the corresponding first mounting plate 21, the lower supporting shaft 3 is rotatably connected to the first through hole, a first movable gap is formed between the first assembly hole and the lower supporting shaft 3, one end of the lower supporting shaft 3 passing through the first assembly hole is fixedly connected with a first limiting plate 31 perpendicular to it, and the horizontal positioning mechanism 4 is mounted on the first mounting plate 21.

[0029] In the above implementation, the design of the first mounting plate 21 facilitates the assembly between the lower connecting seat 11 and the frame 2. The frame 2 and the lower connecting seat 11 can be assembled in rotation by the lower supporting shaft 3 that penetrates the lower connecting seat 11 and the first mounting plate 21. At the same time, since the lower supporting shaft 3 and the lower connecting seat 11 are fixedly connected, the installation position of the lower supporting shaft 3 can be limited by the first limiting plate 31, and finally the axial positioning can be performed with the lower supporting shaft 3 by the horizontal positioning mechanism 4. The overall structural design is simple, and the lower connecting seat 11 and the frame 2 can be assembled in a stable manner in relative rotation.

[0030] As a preferred embodiment, Figure 3 As shown, the horizontal positioning mechanism 4 includes a lower limiting bolt 41, a limiting gasket 42 and a bolt support sleeve 43. The first limiting plate 31 is provided with a first limiting hole, and the lower connecting seat 11 is provided with a screw hole adapted to the lower limiting bolt 41. The lower limiting bolt 41 is horizontally arranged, and its screw portion passes through the first limiting hole and the second assembly hole adapted to the first mounting plate 21, and is threadedly connected with the screw hole of the lower connecting seat 11. The bolt support sleeve 43 passes through the second assembly hole and is sleeved on the outside of the lower limiting bolt 41. The limiting gasket 42 is clamped between the nut of the lower limiting bolt 41 and one end of the bolt support sleeve 43, and the other end of the bolt support sleeve 43 is abutted against the lower connecting seat 11. The limiting gasket 42 is located on the side of the first limiting plate 31 away from the first mounting plate 21, and a second movable gap is formed between the first limiting hole and the second assembly hole and the bolt support sleeve 43.

[0031] In the above implementation scheme, after assembly, the first limit plate 31 is abutted against the first mounting plate 21, and by tightening the lower limit bolt 41, the nut part and the lower connecting seat 11 together clamp the bolt support sleeve 43. After clamping, the limit gasket 42 is close to the first limit plate 31 to achieve stable positioning in the axial direction. In this embodiment, a second movable gap is formed between the first limit hole and the second assembly hole and the bolt support sleeve 43, that is, the bolt support sleeve 43 is allowed to move in the first limit hole and the second assembly hole, ensuring that the transmission box 1 can be rotated and fine-tuned around the lower support shaft when the angle adjustment and locking mechanism 6 are not locked during the installation process.

[0032] As a preferred embodiment, Figure 4 As shown, the frame 2 is provided with a second mounting plate 22 corresponding to the upper connecting seat 12, one end of the upper positioning pin 5 passes through a third assembly hole adapted on the second mounting plate 22, and is connected to a second limiting plate 51, and a third movable gap is formed between the third assembly hole and the upper positioning pin 5.

[0033] In the above implementation scheme, the design of the second mounting plate 22 facilitates the assembly of the upper positioning pin 5 and the frame 2. Since a third movable gap is formed between the third assembly hole and the above upper positioning pin 5, during the installation of the transmission box 1, when the angle adjustment and locking mechanism 6 are not locked, the upper positioning pin 5 can move in the third movable gap, that is, the upper positioning pin 5 is allowed to deflect and shift relative to the eccentric sleeve 7 for fine-tuning. After adjustment, it is locked by the angle adjustment and locking mechanism 6.

[0034] As a preferred embodiment, Figure 4As shown, the angle adjustment and locking mechanism 6 includes an angle adjustment member 61 and a locking assembly 62. The angle adjustment member 61 is connected to the end of the eccentric sleeve 7. The locking assembly 62 is mounted on the second mounting plate 22 and connected to the angle adjustment member 61 for locking or unlocking the angle adjustment member 61.

[0035] In the above-mentioned implementation scheme, the eccentric sleeve 7 is driven to rotate by the angle adjustment member 61, so that the upper positioning pin 5 follows the deflection of the inner hole of the eccentric sleeve 7 (in this process, the axis of the outer circle of the eccentric sleeve 7 remains unchanged, and the axis of the inner hole deflects around the axis of the outer circle). After adjustment, the transmission box 1 can be well assembled by locking it through the locking assembly 62.

[0036] As a preferred embodiment, Figure 4 , 5 As shown in , 6, the angle adjustment member 61 is a sheet metal member with a bayonet 611 at its lower end, one end of the eccentric sleeve 7 is provided with an annular clamping block 71 coaxially connected with its outer circle, one end of the upper positioning pin 5 passes through the clamping block 71, and the angle adjustment member 61 is engaged with the upper part of the clamping block 71 through the bayonet 611.

[0037] In the above embodiment, the angle adjustment member 61 has a simple structural design and can be engaged with the block 71 through the bayonet 611 , so the assembly between the two is very quick and easy.

[0038] In this embodiment, the outer contour of the above-mentioned clamping block 71 is a regular polygon, and the corresponding above-mentioned clamping socket 611 is a polygonal clamping socket matching it. After the two are engaged, when the angle adjustment member 61 is deflected, the clamping block 71 and the eccentric sleeve 7 can be driven to rotate.

[0039] As a preferred embodiment, Figure 4 , 6 As shown, the locking assembly 62 includes a locking bolt 621 and a locking nut 622. The upper end of the angle adjustment member 61 is provided with an arc-shaped waist hole 612. The locking bolt 621 passes through the waist hole 612, the fourth assembly hole adapted on the second mounting plate 22, and the fifth assembly hole adapted on the second limiting plate 51, and is threadedly connected with the locking nut 622.

[0040] In the above embodiment, during installation, the locking nut 622 is not tightened first, so that the angle adjustment member 61 can be operated to drive the eccentric sleeve 7 to rotate, thereby adjusting the deflection of the upper positioning pin 5. During this process, the locking bolt 621 moves along the waist round hole 612. After adjustment, the locking nut 622 is tightened to lock and fix the angle adjustment member 61. This design is simple, and the operation is relatively convenient and flexible.
