Description

[0001]
BACKGROUND OF THE INVENTION
In the present invention, the main frame and the transmission case of the pretreatment body and the trimming body are connected by a link body, and the pretreatment body and the trimming body are supported so as to be rotatable in a horizontal direction via a pivotal support. The present invention also relates to a wrinkle coater provided with an adjusting device for horizontally moving the link body.
[0002]
[Prior art]
It is detachably connected to the rear part of the traveling machine body, receives power from the traveling machine body to the main frame and transmits it to the working part, where the working part cultivates a part of the main fence and the field and raises it in a bowl shape on the former side. The pretreatment body and the drum-shaped trimming body which is formed into a cocoon while rotating the soil cultivated by the pretreatment body are horizontally rotated with respect to the main frame via the link body and the rotation fulcrum and stored. The applicant has proposed a wrinkle coater that can be moved horizontally between the position and the forward work position or the reverse work position (see, for example, Patent Document 1). If the working unit is a work only in the forward working position in the work by the conventional paddy coater, an unworked part remains in the four corners of the paddy field. Through the rotation fulcrum, it is horizontally rotated 180 degrees from the forward working position to the backward working position, and the traveling machine body is moved backward to perform the smearing work. There is a retracted position located approximately in the middle of moving the working unit from the forward working position to the backward working position or from the backward working position to the forward working position, and the working unit is located behind the traveling machine body.
