【考案の詳細な説明】 本考案は、収穫機に係り、主として馬鈴薯等の地下茎作
物を掘取り収穫する種のものに関する。[Detailed Description of the Invention] The present invention relates to a harvesting machine, and mainly relates to a type of harvesting machine for digging and harvesting underground crops such as potatoes.

たとえば馬鈴薯等の地下茎作物を掘取り収穫する場合、
従来、被収穫物としての地下茎作物を掘取るのに先立っ
て茎葉部分を刈取ることが行われ、あるいは茎葉部分を
刈取ることなく被収穫物を掘取って圃場面にいったん放

、これらの方法による場合、作業がきわめて非能率であ
るとともに、被収穫物を損傷しやすく、かつ、被収穫物
と茎葉部分との分離が確実に行われ難い欠点があった。For example, when digging and harvesting underground crops such as potatoes,
Conventionally, the stems and leaves have been harvested before digging underground rhizome crops to be harvested, or the crops have been dug up without cutting the stems and leaves and left in the field and then harvested. However, these methods are extremely inefficient, easily damage the harvested materials, and make it difficult to reliably separate the harvested materials from the stems and leaves. There were drawbacks.

本考案は、このような事情に鑑み提案されたもので、地
下茎作物の掘取り収穫に際し、被収穫物としての地下茎
作物の掘取り作業と同時進行的に被収穫物の茎葉部分の
引抜きおよび分離除去の作業を確実に行うことのできる
収穫機を提供しようとするものである。The present invention was proposed in view of the above circumstances, and it involves pulling out and separating the stems and leaves of the crop to be harvested simultaneously with the excavation work of the underground stem crop as the crop to be harvested. The purpose is to provide a harvester that can perform the removal work reliably.

本考案の一実施例を図面について説明する。An embodiment of the present invention will be described with reference to the drawings.
