ができるなど顕著な効果を奏する。 As is clear from the above embodiments, the present invention provides a grain culm raking device for a combine that is provided with a raking auger 18 for taking in reaped grain culms, and belts 30, 3 which are brought close to and approximately parallel to the auger 18.
A plurality of prevention plates 29 are attached to the auger 18, and the helical guide groove 2 of the auger 18 is installed on the upper side of the auger 18.
7, 28 to insert the prevention plate 29...the distal end side,
Since the spiral guide grooves 27 and 28 are shielded by the prevention plates 29..., the reaped grain culms are scraped in and collected in the center of the grain header 14 during the grain culm conveyance. The prevention member 29 can effectively prevent the grain culm from flying out from the auger 18 in a stepless manner, and as a result, there is no spillage of the grain during grain culm transportation, resulting in efficient grain production. It has remarkable effects, such as being able to transport the culms, reducing harvest losses during harvesting operations, and improving efficiency.
