[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a processing device for tilling residual tilled soil at a furrow of a rotary tilling device.

[0002]

[Prior art]

 Such a furrow processing apparatus is known from Japanese Utility Model Laid-Open No. 6-7401. In the above-mentioned known device, it is described that the earth removal plate is detachably fixed to a side frame (corresponding to the side plate of the present invention) via a mounting bar. It is shown as a plate, and an earth removal plate is attached to its lower end by welding or the like. According to the description of the above publication, the mounting pieces are fixed to the mounting bar at predetermined intervals in the vertical direction by welding or the like. A pair of parallel fixing brackets extending in the vertical direction are fixed to the side frame on which the mounting bar is mounted by tightening the upper and lower ends with bolts, and a pair of upper and lower stoppers are welded across the fixing bracket. The mounting pieces of the mounting bar are inserted into the upper and lower stopper pairs, and the mounting bar is detachably mounted on the side frame. When cultivating a concrete ridge gutter, insert the mounting piece of the mounting bar between the mounting brackets of the side frame (which seems to be an erroneous description of a pair of parallel fixing brackets), and clamp and attach the tractor body to the concrete ridge. Let it run. As a result, the simple structure of the earth removal plate is used because the residual soil immediately after formation is immediately excavated by the earth removal plate by the forward rotation of the rotary tillage nail and guided to the tilling range by the backward rotation of the rotary tillage nail. The remaining soil can be tilled so that weeds do not grow. "
