Therefore, when the clutch needs to be disassembled and replaced, a worker only needs to disassemble the end cover 8 and then pulls the end part of the clutch shaft 6 outwards along the axial direction, so that the clutch shaft 6 slides axially in the clutch sleeve 5 (certainly, the clutch plate 7 is separated from the power connection with the clutch sleeve 5 at the moment), the clutch shaft 6 can be separated from the clutch sleeve 5 and finally pulled out of the box body 1 from the end cover 8, and the disassembling operation of the clutch shaft 6 and the parts such as the clutch plate 7 on the clutch shaft is completed; on the contrary, when the clutch shaft 6 needs to be installed again, the clutch shaft 6 is pushed in from the end cover 8 along the axial direction, so that the front end of the clutch shaft 6 is inserted into the clutch sleeve 5 again.

Compared with the prior art, the embodiment does not need to disassemble the whole transfer case from the machine body, does not need to return a factory to open the transfer case through a special tool, can efficiently and conveniently complete the dismounting operation of the clutch in the transfer case, reduces the manual labor load and improves the dismounting efficiency.

As shown in fig. 2, fig. 2 is a partial structure enlarged view of fig. 1.

In a preferred embodiment with respect to the clutch plate 7, the clutch plate 7 mainly comprises several wet friction plates. Specifically, each wet friction plate is overlapped and sleeved on the clutch shaft 6, and the outer edge of each wet friction plate is abutted against the inner wall of the clutch sleeve 5. When oil is supplied between the wet friction plates, the wet friction plates slip mutually due to lubrication of the oil, so that the wet friction plates cannot transmit torque; when the wet friction plates are pressed by relevant parts in the clutch, oil is discharged, the wet friction plates are tightly combined and form friction transmission with the inner wall of the clutch sleeve 5, so that the clutch shaft 6 is driven to synchronously rotate under the rotation of the clutch sleeve 5, and the fan is driven to operate.

In a preferred embodiment of the end cap 8, considering the large axial length of the clutch shaft 6, the end cap 8 in this embodiment is embodied in a split structure, mainly comprising an outer cap 81 and an inner cap 82, for ease of installation and support. The outer cover 81 covers the extending end 61 of the clutch shaft 6 and is mainly used for installing the extending end 61, and the inner cover 82 is connected between the outer cover 81 and the box body 1 and is mainly used for installing parts such as a clutch plate 7 in the middle of the clutch shaft 6. With such an arrangement, when the clutch shaft 6 needs to be detached and replaced, the whole clutch shaft 6 can be pulled out from the end cover 8 by applying force to the outward extending end 61 of the clutch shaft 6 only by opening the outer cover 81 and the inner cover 82.

Of course, the end cap 8 may be of unitary one-piece construction.

In a preferred embodiment of the case 1, the case 1 mainly includes a front case 101 and a rear case 102, which are fastened to each other to be easily detachable. Accordingly, the coupling end 62 of clutch shaft 6 (typically provided with internal splines for coupling with a fan shaft) is disposed within front housing 101, while the outwardly extending end 61 of clutch shaft 6 is disposed within rear housing 102. Meanwhile, the end cap 8 is disposed on the rear case 102, and is generally disposed at a side position of the rear case 102.

Further, to facilitate the connection of the end cover 8 and the case 1, in the present embodiment, the inner cover 82 is detachably connected to the rear shell 102 by a fastener such as a bolt. Similarly, to facilitate the connection between the inner lid 82 and the outer lid 81, in the present embodiment, the inner lid 82 is detachably connected to the outer lid 81 by a fastener such as a bolt.

Further, in order to support the clutch shaft 6, and to ensure the rotational stability and the axial sliding smoothness of the clutch shaft 6, the present embodiment is further provided with a front end bearing 9 in the front housing 101, and a rear end bearing 10 in the inner lid 82. Specifically, the front end bearing 9 is sleeved on a connecting end 62 of the clutch shaft 6 and is mainly used for supporting the front end part of the clutch shaft 6, and the rear end bearing 10 is sleeved on an extending end 61 of the clutch shaft 6 and is mainly used for supporting the rear end part of the clutch shaft 6. Of course, this embodiment also has a central bearing in the clutch sleeve 5 to support the central portion of the clutch shaft 6.

In a preferred embodiment with respect to the power input assembly 3, the power input assembly 3 mainly includes an input shaft and an input gear, and is integrally located in a middle region of the case 1. The input shaft is generally connected to an output shaft of the engine to transmit power of the engine and is driven by the engine to rotate. The input gear is sleeved on the input shaft, rotates synchronously with the input shaft, and drives the subsequent second output assembly 11 and the third output assembly 12 to rotate through the input gear.

Further, in the present embodiment, a power coupling member 31 is connected to one end of the input shaft so as to be coupled to the output shaft of the engine through the power coupling member 31. Meanwhile, the other end of the input shaft is also connected with a driving oil pump 2, so that the input shaft drives the driving oil pump 2 to operate, further the transfer case oil is driven to circularly flow, cooling and lubricating conditions are provided for the transfer case, and the separation and combination actions of the clutch and the like are realized.

In a preferred embodiment with respect to the first output assembly 4, the first output assembly 4 is primarily a first output gear. In particular, the first output gear forms a meshing transmission with the input gear in the power input assembly 3 to rotate synchronously with its rotational movement. Meanwhile, the clutch sleeve 5 is axially connected to an end surface of the first output gear, and the clutch shaft 6 is inserted inside the clutch sleeve 5. So set up, when first output gear is rotatory, will drive separation and reunion cover 5 rather than synchronous revolution, later drive separation and reunion axle 6 again and rotate under the transmission of separation and reunion piece 7.

In addition, considering that the first output member 4 is generally disposed at a side position of the case 1, and a transmission distance exists from the power input member 3 in the central region, in order to facilitate power transmission, the present embodiment adds the second output member 11 between the power input member 3 and the first output member 4, so that the transmission distance is increased by the second output member 11 serving as a transmission member between the power input member 3 and the first output member 4. Of course, the second output assembly 11 itself is also used to drive the intended target into operation.

Furthermore, to increase the power take-off chain of the power input unit 3, a third output unit 12 is added to the box 1 on the other side, and the third output unit 12 is also connected to the output of the power input unit 3 for outputting the power of the driving part 2 to different mechanisms on the cotton picker.

The embodiment further provides a cotton picker, which mainly comprises a machine body and a quick release clutch transfer case arranged on the machine body, wherein the specific content of the quick release clutch transfer case is the same as the related content, and the details are not repeated herein.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model.
