PROBLEM TO BE SOLVED: To provide a paddy field weeding work machine raking off weeds from a paddy surface, cutting the weeds floated on water surface without neglecting the weeds, and thereby preventing the weeds from rooting again in soil on the paddy surface even when the weeds sink on the paddy surface after weeding work to rake off the weeds efficiently in paddy field weeding work.SOLUTION: A paddy field weeding work machine W includes: a travel machine 1 a grass cutting device 6 arranged on a front side of the travel machine 1, including a height adjustment mechanism capable of adjusting a height with respect to the travel machine 1, having plural cutters 65 arranged respectively at positions between rice plants in weeding work and rotated vertically, and cutting weeds floated on water surface by the cutters 65 and a weed raking device 5 arranged in front of the weed cutting device 6 and raking off the weeds around the rice plants by raking the paddy surface by raking bodies 52 including linear bodies 524 having a disk-like rotation track and inclined at a predetermined angle with respect to a horizontal direction so that a travel direction side is lowered.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】水田の除草作業で、田面から雑草を掻き取り、水面に浮いた雑草をそのまま放置せず切断して、除草作業後に雑草が田面に沈んでも根付くことがないようにしたものにおいて、雑草の掻き取りをより効率的に行うことができるようにした水田除草作業機を提供する。【解決手段】水田除草作業機(W)は、走行機(1)と、走行機(1)の前方に配されており、走行機(1)に対する高さの調節ができる高さ調節機構を有し、除草作業時において稲株の条間となる位置にそれぞれ設けられた上下方向に回転する複数のカッター(65)を有すると共にカッター(65)が水面に浮いた雑草の切断を行う草切断装置(6)と、草切断装置(6)の前方に配され、線条体(524)の回転軌跡が円盤状で走行方向側が下がるように水平方向に対し所要角度で傾斜している掻取体(52)で田面を掻いて稲株の周りの雑草を掻き取る草掻取装置(5)とを備える。【選択図】図1
