PROBLEM TO BE SOLVED: To provide a walk operation type crop pullout machine which includes a pullout part adjustable in height, pulls out a crop midway, and reliably leaves the crop in an erected state in a field.SOLUTION: A pullout machine includes in a manner supported integrally on a work frame 5: a steering handle 2 for walk operation a gear change transmission device 3 a pullout device 4a and a foliage removal device 4b, etc. The pull out machine also includes: a travel transmission case 6a connected with the gear change transmission device 3 and transmission-supporting a travel wheel 6 so as to be rotated vertically and a ground contact member 7 supporting an edge of the work frame 5. The ground contact member 7 is supported by the work frame 5 via an integral support leg 7a so as to be rotated vertically, and the travel transmission case 6a and the support leg 7a are connected with a connection rod 8a mutually parallelly to support the work frame 5 in a parallel link shape. Thereby, a support height can be adjusted without changing a posture of the pullout device 4a.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】引抜部を高さ調節可能とした上で、作物を半ばまで引抜いて圃場に確実に起立残置する歩行操作型の作物引抜機を提供する。【解決手段】作物引抜機は、歩行操作用の操縦ハンドル(2)、変速伝動装置(3)、引抜装置(4a)、茎葉除去装置(4b)等を一体に作業フレーム(5)に支持し、前記変速伝動装置(3)と接続して上下回動可能に走行輪(6)を伝動支持する走行伝動ケース(6a)と、前記作業フレーム(5)の端部を支持する接地部材(7)とを備えて構成され、前記接地部材(7)は、一体の支持脚(7a)を介して上下回動可能に前記作業フレーム(5)に軸支し、前記走行伝動ケース(6a)と前記支持脚(7a)とを互いに平行に連結ロッド(8a)で連結して平行リンク状に前記作業フレーム(5)を支持することにより、引抜装置(4a)の姿勢変化なしに支持高さ調節を可能とするものである。【選択図】図1
