[0002] A transfer case is a device that distributes output power, allowing power to be simultaneously output to different shafts. Different types of transfer cases are required for different equipment.

[0003] A Chinese utility model patent with publication number CN211020064U discloses a transfer case for a whole-stalk sugarcane harvester, comprising a transfer case body. A shaft hole is provided at the upper end of one side of the transfer case body, and an output shaft is fixedly installed at the lower end of one side of the transfer case body, with the output shaft located below the shaft hole. A connecting frame is welded to the middle of the other side of the transfer case body. A square groove penetrating the connecting frame is formed in the middle of one side of the connecting frame. Limiting mechanisms are provided on both sides inside the square groove and connected to a connecting pin through the limiting mechanisms. A connection is also provided between the connecting pin and the connecting frame. The transfer case is equipped with a fastening mechanism. Two sets of auxiliary fixing mechanisms are also provided on one side of the transfer case body, and the connecting frame is located between the two sets of auxiliary fixing mechanisms. The auxiliary fixing mechanism includes two hinge seats installed on one side of the transfer case body and a support rod connected to the vehicle body. An upper arc plate and a lower arc plate are respectively hinged in the two hinge seats. The lower arc plate and the upper arc plate are configured the same. The support rod is located inside the lower arc plate and the upper arc plate. The support rod is clearance-fitted with the lower arc plate and the upper arc plate. The other side of the upper arc plate and the lower arc plate is fixed by bolts.

[0004] The transfer cases in existing sugarcane harvesters on the market have low transmission efficiency, high energy loss, and low wear resistance. During operation, the transfer cases are prone to blockage and are difficult to maintain later. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a sugarcane machine transfer case.

[0006] The sugarcane machine transfer case of this utility model includes a gearbox, a connecting seat fixedly connected inside the gearbox, a support seat rotatably connected to the connecting seat, a connecting shaft and a drive gear fixedly connected to the support seat, an output gear meshing with the drive gear, an oil pump shaft connected to the output gear, an elastic plate assembly fixedly connected to the connecting shaft, and an end cover corresponding to the connecting seat on the gearbox.

[0007] The gearbox is fixedly connected to a middle section, which is rotatably connected to a support base.

[0008] The middle section is equipped with a cover plate at the top.

[0009] The gearbox is equipped with an oil filling hole and an oil drain hole at the bottom.

[0010] The gearbox is also equipped with a lifting ring.

[0011] The connection between the connecting seat, the support seat, and the connecting shaft is provided with a bearing.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model features high torque transmission capability, adapts to various complex road conditions, and has a dustproof design that ensures the transfer case remains relatively clean during operation, preventing sugarcane scraps from entering. It also boasts wear-resistant and vibration-resistant performance, with the transfer case's rotating seals made of wear-resistant and high-temperature-resistant materials. Furthermore, the assembly features a vibration-resistant and high-efficiency transmission structure, enabling the transfer case to operate with high torque and high efficiency. In addition, the transfer case has a small overall size, facilitating the wiring layout and installation of the entire machine. Its simple structure and lightweight design save costs.
