PROBLEM TO BE SOLVED: To provide a revolutionary weeding apparatus with which weeds are selectively removed from a mud surface without preventing growth of crops.SOLUTION: The weeding apparatus has a constitution that a travel body 1 traveling on the mud surface 7 is equipped with a weeding body 2 which is pulled, traveling and furnished with a mud surface scratching means A in which the lower ends of a plurality of linear bodies 3 are sunk in mud 7 and the sinking depth L of each linear body 3 is set in fixed depth L which reaches the root of a weed (a) growing in the mud surface 7 but does not reach the root of a crop b and a weed catching means B in which the lower end sides of a plurality of linear bodies 5 are brought into contact with the mud surface 7, equipped with lower end side catching projection parts 5a of the linear bodies 5, the catching projection parts 5a of the linear bodies 5 catch a weed (a) growing in the mud surface 7, remove it from the mud surface 7 and are set in proper flexibility so that when the catching projection parts 5a are brought into contact with a crop b growing in the mud surface 7, the linear bodies 5 are bent by the contact pressure with the crop b, the catching parts 5a are rotated right and left relatively to the crop b and do not remove the crop b from the mud surface 7.COPYRIGHT: (C)2007,JPO&INPIT【課題】作物の生育を防除することなく泥面から雑草だけを選択的に除去できる画期的な除草装置を提供する。【解決手段】複数の線体3の各下端を泥面7に沈み込ませこの各線体3の沈み込み深さLを前記泥面7に生える雑草aの根に到達し且つ作物bの根に到達しない所定深さLに設定した構成の泥面引掻き手段Aと、複数の線体5の各下端側を前記泥面7に当接すると共に各線体5の下端側に引掛け突部5aを設け、この各線体5の引掛け突部5aが前記泥面7に生える雑草aを引っ掛けて泥面7から除去し、且つこの引掛け突部5aが前記泥面7に生える作物bに当接した際にはこの作物bとの当接押圧により線体5が撓み前記引掛け突部5aが作物bに対して左右に回避動してこの作物bを泥面7から除去し得ないように各線体5を適宜な可撓性に設定した構成の雑草引掛け手段Bとを備えた除草体2を、前記泥面7を走行する走行体1に牽引走行自在に設けた構成の除草装置。【選択図】図1
