Description

[Detailed Description of the Invention] The present invention relates to an improvement of a culm collecting device such as a combine harvester.

This type of device supports one side of a collecting shaft provided with a culm receiver in a cantilever, and releases the collecting culm while rotating in the direction of movement of the aircraft around this cantilevered support shaft. However, this type of conventional device utilizes the rotational force of the culm support to rotate downward when the weight of the culm accumulated on the culm support exceeds a set weight, and the cantilever support shaft is Since the material is discharged while rotating the collecting shaft horizontally around It is not possible to release it to the desired field location, and in many cases the waste culms are simply scattered while being released, which has the disadvantage that post-processing of the waste culms requires a lot of manpower, and improvements are desired in these points. Ta.

The present invention was developed in response to these circumstances, and has a simple structure that eliminates the drawbacks of the conventional technology.The culm shaft is forcibly rotated horizontally when a signal indicates that the amount of culm discharged has reached a set weight. The aim is to improve post-treatment efficiency by ejecting the waste culm in a concentrated manner at a predetermined position without scattering the waste culm along the way.
