PROBLEM TO BE SOLVED: To provide a puddling machine capable of leveling the whole ground of a field by gathering muddy water, straw, or the like pushed to the side of a traveling machine body and surely guiding them to the middle part of the puddling machine.SOLUTION: The puddling machine 1 attached to the back of a traveling machine body 90 is provided with a first leveling board 19 turnably placed at the back of a tilling rotor rotating by the power transmitted from the traveling machine body 90 and a second leveling board 20 turnably placed at the rear end of the first leveling board 19. Tilling work is performed by the tilling rotor rotating and moving together with the traveling motion of the traveling machine body 90, and the field surface is leveled by the first leveling board 19 and the second leveling board 20. The second leveling board 20 has a bilaterally symmetrical structure having a straight part 24 extending in a lateral direction relative to the traveling direction of the machine body 5 and inclined parts 25 connected to both ends of the straight part and directed inward to the right and left directions. Assisting leveling boards 40 are attached to the right and left ends of the second leveling board 20, and the muddy water, straw, or the like on the field are guided to the middle part of the second leveling board 20 by the assisting leveling boards 40 and the inclined parts 25 of the second leveling board 20.COPYRIGHT: (C)2009,JPO&INPIT【課題】走行機体の側方に押し出された泥水や藁等を確実に代掻き作業機の中央よりに導いて、圃場表面の全てを均平に整地する。【解決手段】代掻き作業機1は、走行機体90の後部に装着され、走行機体90から伝達される動力によって回転する耕耘ロータの後側に第1整地板19を回動可能に設け、第1整地板19の後端部に第2整地板20を回動可能に設け、耕耘ロータが回転しながら走行機体90の走行とともに進行して耕耘作業を行うとともに、第1整地板19及び第2整地板20によって圃場表面を整地する。第2整地板20は、機体5の進行方向に対して左右方向に延びる直線部24と、この左右両端部に接続されて進行方向に対して左右方向内側に向く傾斜部25とを有して左右対称構造をなす。第2整地板20の左右両端部には補助整地板40が設けられ、補助整地板40及び第2整地板20の傾斜部25によって圃場の泥水や藁等を第2整地板20の中央側へ案内する。【選択図】図2
