DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain stalk raising device for a combine, and more particularly to a grain stalk raising device provided in a mowing device, which assists in raising a lodging grain stalk along a front side of a main grain stalk raising case. It can be used for things with auxiliary grain stem raising case.

[0002]

2. Description of the Related Art In a large-scale combine harvester with multiple cuttings, the grain culm falls down, and the grain culm provided on the cutting device is entangled with an adjacent grain culm row due to disturbance of the culm body. If the raising device is only the main cereal stem raising case, the raising operation of the lodging cereal stem is hindered, and in recent years, the main grain stem raising case is made to correspond to each main grain stem raising case along the front side of the main grain stem raising case. By arranging the auxiliary cereal stem raising case parallel to the advancing direction of the aircraft, it is possible to disentangle with the adjacent cereal stem row before the main cereal stem raising case is raised. The raising operation by the case can be performed smoothly.

[0003] However, the transmission structure of the auxiliary cereal stem raising case has conventionally been such that the upper side of each auxiliary cereal stem raising case is connected by a horizontally long transmission case, and only one end thereof is provided. Power is supplied, and the auxiliary grain stem raising case at the right end, which is not necessarily required in the counterclockwise harvesting operation, is also integrated with the power transmission, so that the harvesting operation is mainly performed counterclockwise. In some cases, unnecessary weight and cost are added due to the auxiliary cereal stem raising case at the right end, the operator's view is obstructed by the transmission case at the right end, and operation is obstructed. Is performed from only one side, there are many factors that are disadvantageous in terms of functionality, economy, operability, and durability, such as concentration of load and reduction in durability.

Accordingly, the present invention provides a cereal stem raising device for raising and treating a lodging cereal stem, wherein the transmission structure of an auxiliary cereal stem raising case arranged corresponding to the main cereal stem raising case has a function and a function.
The present invention is designed to be advantageous in terms of economy, operability, and durability.
