Description

Technical Field

[0001] The present application relates to the technical field of gearboxes, for example, to a compound multi-speed gearbox and a silage machine. Background Art

[0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

[0003] In existing technology, the cutting gearbox and front feed transmission box of a silage machine are typically separated into two independent components. This design not only increases the complexity of the machine but also leads to energy loss and reduced efficiency during the transmission process. Specifically, the two independent boxes require separate drive systems, which not only takes up more space but also makes the overall layout of the machine less compact and coordinated. In addition, traditional transmission methods often use complex chain or belt drives, which are not only costly to maintain but also prone to wear, further reducing the reliability and service life of the machine. Summary of the Invention

[0004] This application provides a composite multi-speed transmission and a silage machine. By integrating the cutting transmission and the front feed transmission into a single unit, this system achieves dual functions. This integrated design not only simplifies the machine structure and reduces transmission links, thereby reducing energy loss and improving operating efficiency, but also makes the overall layout more compact and coordinated, improving the overall aesthetics and practicality of the machine.

[0047] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0048] Combine Figure 1-6As shown, the embodiment of the present disclosure provides a compound multi-speed gearbox, comprising: a housing 9, a main input shaft 2, a first intermediate shaft 3, a second intermediate shaft 4, a plurality of speed change gears, a first output shaft 16, a shift gear 17, a third intermediate shaft 5, a fourth intermediate shaft 6, and a second output shaft 7;

[0049] The box body 9 has a receiving cavity; the box body 9 is a metal box body 9 with a sealed cavity.

[0050] The main input shaft 2 is partially rotatably arranged in the housing 9 and partially connected to the power mechanism 1 in transmission mode. One end of the main input shaft 2 is sealed with the housing 9 through a plug cover 14 and a bearing 15, and the other end extends out of the housing 9 and is connected to the motor shaft.

[0051] The first intermediate shaft 3 is rotatably arranged in the housing 9 and meshes with the main input shaft 2;

[0052] The second intermediate shaft 4 is actively arranged in the housing 9 and meshes with the first intermediate shaft 3;

[0053] A plurality of speed change gears are provided on the second intermediate shaft 4;

[0054] The first output shaft 16 is partially rotatably disposed in the housing 9;

[0055] The shift gear 17 is movably mounted on the first output shaft 16 and selectively engages with a plurality of speed gears. An axial groove is provided on the surface of the first output shaft 16, and the shift gear 17 slidably engages with the axial groove, limiting the shift gear 17 from sliding along the axis of the first output shaft 16. The shift gear 17 is provided with teeth corresponding to the plurality of speed gears.

[0056] The third intermediate shaft 5 is rotatably arranged in the housing 9 and meshes with the second intermediate shaft 4;

[0057] The fourth intermediate shaft 6 is rotatably arranged in the housing 9 and meshes with the third intermediate shaft 5; one end of the first intermediate shaft 3, the second intermediate shaft 4, the third intermediate shaft 5, and the fourth intermediate shaft 6 are rotatably connected to the inner wall of the cavity of the housing 9 through bearings 15, and the other ends are sealed with the housing 9 through bearings 15 and a blocking cover 14.

[0058] The second output shaft 7 is partially rotatably arranged in the housing 9 , is perpendicular to the fourth intermediate shaft 6 , and is transmission-connected to the fourth intermediate shaft 6 via a bevel gear set 8 .

[0059] The composite multi-speed transmission provided by the disclosed embodiments integrates the cutting transmission and the front feed drive box into a single unit, achieving dual functions. This integrated design not only simplifies the machine's structure and reduces transmission links, thereby reducing energy loss and improving efficiency, but also makes the overall layout more compact and coordinated, enhancing the machine's aesthetics and practicality.

[0060] In some embodiments, the plurality of speed change gears include:

[0061] The high-speed gear 12 meshes with the first intermediate shaft 3 and the third intermediate shaft 5;

[0062] The medium-speed gear 10 is arranged opposite to the high-speed gear 12;

[0063] The low-speed gear 11 is located between the high-speed gear 12 and the intermediate-speed gear 10, and is spaced apart from each other. This spaced area is the neutral zone. When the shift gear 17 moves to the spaced area, it no longer meshes with the intermediate-speed gear 10 on the second intermediate shaft 4, and other gears also do not mesh, achieving a neutral gear effect.

[0064] The compound multi-speed transmission provided in the disclosed embodiments adjusts the transmission ratio by adjusting the gear position, enabling the production of silage in three lengths: 15mm, 24mm, and 32mm. This design allows users to quickly adjust silage length based on actual needs, significantly improving work efficiency and operability. This flexibility also meets the diverse needs of farmers for silage length.

[0065] In some embodiments, the compound multi-speed transmission further includes:

[0066] The shift mechanism 18 is provided on the housing 9 and drives the speed change gear to move. The shift mechanism 18 is a conventional technical means well known to those skilled in the art. For ease of understanding, a brief description is given here. The shift mechanism 18 includes a rotating shaft, a rotating arm, a shift lever 19, and a handle 20. The rotating shaft is rotatably provided on the housing 9. The speed change gear is provided with an annular slide groove. The shift lever 19 is provided within the housing 9 and slides in the slide groove. The shift lever 19 is rotatably connected to the rotating arm, which is fixedly connected to the rotating shaft. The handle 20 is provided outside the housing 9 and is fixedly connected to the rotating shaft. Rotating the handle 20 drives the rotating shaft to rotate, which drives the rotating arm to rotate, and the shift lever 19 is also driven to move, thereby driving the speed change gear to move and shift.

[0067] In some embodiments, the power mechanism 1 includes: a hydraulic motor.

[0068] In some embodiments, the first intermediate shaft 3 includes: dual teeth on the driving and driven shafts;

[0069] The driving and driven shaft duplex gears are located on the first intermediate shaft 3 and mesh with the main input shaft 2 and the second intermediate shaft 4, respectively. The driving and driven shaft duplex gears consist of two coaxially connected gears in parallel. One gear is driven by the main input shaft 2, while the other acts as a driven gear, rotating synchronously with the driving gear. These two gears have different numbers of teeth (or, in some cases, the same). The driven gear meshes with the high-speed gear 12 of the second intermediate shaft 4.

[0070] In some embodiments, the third intermediate shaft 5 includes: a first constant meshing main and driven gear 13;

[0071] The first constantly meshed main and driven gears 13 are provided on the third intermediate shaft 5 and mesh with the high-speed gear 12 .
