Description

DETAILED DESCRIPTION OF THE INVENTION ``Industrial Application Field'' The present invention relates to a sun visor device for a combine harvester, which is provided with a sun visor for a sunshade on the driver's seat side.

``Prior Art'' Conventionally, sun visors used in combine harvesters are usually fixed, and even if they are movable, the sun visor is either rotated around a support column or moved in one direction.

"Problems to be Solved by the Invention" However, in the case of rotary movement as described above, it is impossible to lower the installation height when the overall height of the sun visor is required to be controlled, and it is impossible to lower the mounting height of the sun visor when it is necessary to control the overall height of the sun visor. However, the method of lowering the installation height of the sun visor has the disadvantage that it obstructs the front or rear visibility from the driver's seat position, resulting in a reduction in safety and work efficiency.

"Means for Solving the Problem" Therefore, the present invention supports the sun visor on the aircraft body via a parallel link that moves the driver's seat appropriately to the left and right sides, and provides the sun visor to be movable to the left and right sides of the aircraft body. It is something that

"Function" According to the present invention, when the mounting height of the sun visor is lowered due to overall height regulations for road driving, etc., the sun visor is positioned on the left and right sides, so that the front or rear visibility is improved. The sun visor can be moved to the entrance supply plate at the entrance of the threshing section and can be used to protect the rice from the rain when it starts to rain. Moreover, it can also be used as a mobile balancer to improve the balance of the aircraft body by moving the sun visor left and right depending on the amount of paddy loaded.
