Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically a gearbox for a corn harvester. Background Technology

[0002] The existing corn harvester uses a single-function gearbox with only one output shaft. It requires additional mechanisms to meet the needs of the corn harvester, resulting in a complex structure, large space occupation, and high manufacturing cost, which is not conducive to the overall layout of the corn harvester. Summary of the Invention

[0003] The purpose of this invention is to provide a gearbox for a corn harvester to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A gearbox for a corn harvester includes a housing, a shaft, an input end, and a first output shaft. The shaft passes through the housing, and the first output shaft is located at the other end of the housing. The first output shaft is perpendicular to the shaft. The shaft meshes with the first output shaft through several gears and shafts within the housing. The first output shaft can output three forward rotations and one reverse rotation. The power output from the first output shaft is used to drive the header of the corn harvester. Looking from the first output shaft towards the shaft, the right side of the shaft has an input end, and the left side of the shaft has a second output end. The power output from the second output end is used to drive the hoist of the corn harvester.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] 1. A gearbox has two output shafts. Using one gearbox can simultaneously meet the needs of the header and the hoist of the corn harvester. It has a simple structure, occupies little space, facilitates the layout of the corn harvester, and reduces manufacturing costs.

[0008] 2. The first output shaft of the cutting table can output three forward rotations and one reverse rotation, which meets the working needs of the cutting table. Attached Figure Description

[0009] Figure 1 This is a cross-sectional view of the present invention. Detailed Implementation

[0010] Please see Figure 1As shown, a gearbox for a corn harvester includes a housing 1, a shaft 2, an input end 3, and a first output shaft 4. The shaft 2 passes through the housing 1, and the first output shaft 4 is located at the other end of the housing 1. The first output shaft 4 is perpendicular to the shaft 2. The shaft 2 meshes with the first output shaft 4 through several gears and shafts inside the housing 1. The structure of several gears and shafts meshing with the first output shaft 4 is prior art, and the specific structure will not be described in detail. The first output shaft 4 can output three forward rotations and one reverse rotation. The power output by the first output shaft 4 is used to drive the header of the corn harvester. Looking from the first output shaft 4 towards the shaft 2, the right side of the shaft 2 has the input end 3, and the left side of the shaft 2 has the second output end 5. The power output by the second output end 5 is used to drive the hoist of the corn harvester.
