Description

[Detailed description of the invention] Industrial applications The present invention relates to a grain extraction device such as a combine harvester.

Prior Art and Problems to be Solved by the Invention In harvesting operations using a combine harvester or the like that uses a grain tank, the harvested grains are stored in this grain tank, and the stored grains are full. When this occurs, in order to change the tX kernel from the stowed state to the non-stored state, the grain discharging barrel is rotated to the discharge side and the discharge height is adjusted to transport the grains to a truck on the ridge. Grain discharge work is carried out, but this harvesting work is carried out until dusk in order to harvest in a short period of time.
Generally, a working light is provided at the tip of the grain threshing barrel to confirm the discharge of grains, and when working at dusk, the working light is turned on when the grain threshing pipe is not stored, and the working light is turned on when the grain threshing pipe is not stored. , ＋ requires a switch operation such as turning off the light, and 1 turns on and off!
/J ++ I forget and these operations are troublesome.

Means for Solving the Problems The present invention provides a structure in which the grains discharged from the grain tank (1) are communicated with the upper end of the grain lifting cylinder (2) for frying the grains, and the structure around the grain lifting cylinder (2) is Grain shovel (3
), a working light (4) is provided at the tip of the grain removal tube (3), and a detection 'jA' is provided to detect whether the grain removal tube (3) is stored in a predetermined position or not stored 5E. (5) is provided,
The structure of a grain discharge device such as a combine harvester is such that the work light (4) is turned off and on in conjunction with the detection by the detector (5).

Functions and Effects of the Invention Grain harvested by a combine harvester or the like is stored in a grain tank (1), and the grains discharged from this grain tank (1) are fried by a grain lifting cylinder (2). So, here? L cylinder (2)
The grain ejecting cylinder (3), which communicates with the upper end and is stored in a predetermined position on the upper part of the machine, is rotated around the grain ejecting cylinder (2) and in the vertical direction to set the grain ejection position to the ejection position. However, the work light (4) provided at the tip of the exhaust pipe (3) is
If this detector (5) detects the stored state of the grain shovel (3) in conjunction with the detector (5) that detects the stored state and non-stored state of the grain shovel (3), In conjunction with this, the light is turned off, and if a non-storage state is detected, the light is turned on, and the grain removal tube (3
) is in the grain discharge state, the grain discharge operation X is performed with the work light (4) turned on.
