PROBLEM TO BE SOLVED: To provide a drawing marker device of an agricultural working machine, the device that can universally be mounted to various agricultural working machines such as a fertilizing machine or a seeding machine, also facilitates the attachment and detachment, and can easily be driven by a power supply of voltage 12 V of a tractor being the present machine.SOLUTION: A drawing marker device A is provided near a side of an agricultural working machine and making a drawing marker unit 9 be freely protruded and stored. A drive motor M is integrally supported in the drawing marker device A. A base of a marker support rod 8 for supporting the drawing marker unit 9 is fitted in a drive rotary shaft 2 driven by the drive motor M. The drawing marker unit 9 can be rotationally operated in the vertical direction between a state of a perpendicular storage position in the lifting and a state of a working position of the horizontal projection in the lowering using the base of the marker support rod 8 as a fulcrum by the turning of the drive rotary shaft 2 based on the rotational force of the drive motor M.SELECTED DRAWING: Figure 10COPYRIGHT: (C)2018,JPO&INPIT【課題】施肥機や播種機等の多種多様の農用作業機に対して汎用的に装着することができ、その着脱も容易で、本機であるトラクタの電圧12Vの電源により簡単に駆動可能とした農用作業機の線引きマーカ装置を提供する。【解決手段】農用作業機の側方に付設して線引きマーカ部9を突出収納自在とする線引きマーカ装置Aにおいて、前記線引きマーカ装置Aに、駆動モータMを一体的に支持し、前記駆動モータMにより駆動する駆動回転軸2に、前記線引きマーカ部9を支持するマーカ支持杆8の基部を嵌装し、前記駆動モータMの回転力による駆動回転軸2の回動により、前記マーカ支持杆8の基部を支点として、前記線引きマーカ部9を、上昇時の垂直の収納位置の状態と、下降時の水平突出の作業位置の状態とに、上下方向に回転動作可能に構成とした。【選択図】図10
