PROBLEM TO BE SOLVED: To provide a crop harvester equipped with a pair of endless belts comparatively easily extracting the crops from a field by nipping the stems and leaves of the crops.SOLUTION: The pair of the belts 28a for conveyance to be attached to a conveying device for nipping and conveying an article has voids in the inside and protruded parts 28aa formed by extruding the parts 28aa from the nipping operation face-side in the insides of the cavities to the attaching face-sides. The base part of the protruded part 28aa is lateralized from the center part of the nipping operation face, and the tip part of the protrusion part 28aa is positioned at the vicinity of the center part of the attaching face. A movement-restricting part 28ak for restricting the movable range of the protruded part 28aa is formed in the inside of the attaching face. The range of the protruded part 28aa movable according to the force added to the nipping and conveying belt 28a is widened because the protruded part 28aa takes a tilted posture to allow the nipping force caused by the nipped crop to be set finely. As a result, the operation efficiency and the breakage-preventing effects of the article are improved than those by the conventional one.COPYRIGHT: (C)2010,JPO&INPIT【課題】作物の茎葉を挟み込んで圃場から引く抜くことが比較的容易な一対の無端帯を備えた作物収穫機を提供すること。【解決手段】物品を挟持搬送する搬送装置に装着する一対の搬送用ベル28aに内部に空洞と該空洞内部の挟持作用面側から装着面側に伸ばして設けた突起部28aaを設け、該突起部28aaの基部を挟持作用面の中央部から偏倚させ、また突起部28aaの先端部を装着面の中央部付近に位置させ、さらに装着面内側に突起部28aaの移動範囲を規制する移動規制部28akを形成している。該突起部28aaは傾斜姿勢となるので、該突起部28aaが挟持搬送ベルト28aにかかる力に応じて移動できる範囲が広くなり、挟持する作物に応じた挟持力を細かく設定することができ、作業能率の向上や物品の破損防止効果が従来より向上する。【選択図】図3
