威しである湿田作業機に関する。[Detailed description of the invention] This invention is based on a lift arm that is attached to the rear of the traveling aircraft so that it can be driven up and down around the horizontal axis, and that the swinging end of the lift arm is connected to the upper left and right sides of the One end of the link is attached, and one end of a pair of left and right lower links is pivotally attached to the rear end of the machine below the swing fulcrum of the lift arm, and the other ends of both links are attached to the left and right of the work equipment. Connected on both sides so that they are located approximately on the same axis,
Both links are installed so as to form a V-shape that widens on the side closer to the fuselage when viewed from the side, and further, the relay coupling device:
A swinging member that connects the end of the top link on the body side is pivotally connected to a fixed member fixed to the lift arm side at a point in the center between connection points of the swinging member, and
The present invention relates to a wet field working machine that is configured to allow the working device to swing from side to side during work.

に保てるので、常に、左右での植付は深さを一定又はほ
ぼ一定に保持できる利点がある。In such a wet field working machine, for example, a rice transplanter, when planting, regardless of the change in the horizontal slope of the mud surface or the horizontal slope of the machine body, planting is carried out by the grounding action of the device on the mud surface. Since the plant can be independently and automatically swung to the left and right so that it is in a parallel posture, planting left and right has the advantage that the depth can always be kept constant or almost constant.

する点にある。The present invention is an improvement of a wet field working machine having such advantages, and its purpose is to solve the problem that arises due to the construction of a working device such as a planting device so that it can swing from side to side. When the planting device is raised above the ground during aircraft travel or on the road, the planting device may swing from side to side as it comes off the ground, causing the seedlings placed on the seedling tray to collapse or The aim is to rationally solve the problem of bad situations such as seedlings falling off.

作するロック機構を装着しであることを特徴とする。The wet field work machine according to the present invention, as described at the beginning, detects a change in the amount of expansion between the upper link and the lower link as the lift arm swings up and down. In addition to providing an expansion amount detection mechanism,
For the relay coupling device, when the expansion amount detection mechanism detects that both links are expanded by a predetermined amount or more, the swinging member is forcibly operated to take a parallel attitude with respect to the fixed member. It is characterized by being equipped with a locking mechanism.

に防止できるに至った。That is, according to the present invention, in some cases, when planting is done with a working device such as a planting device on the ground, the planting device is automatically placed in a state that allows the device to swing from side to side, and when planting is done, the device is raised above the ground. Sometimes, the non-planting can be done automatically, and the right and left swing of the planting device can be fixed, so no special operation is required. The depth of planting on the left and right can be maintained at a constant level by automatically swinging the device left and right to ensure that the planting depth is constant. It has now been possible to reliably prevent collapse, seedlings, etc.
殊に、本考案では、植付は装置の特上げに伴って植付は

る。In particular, in the present invention, as the planting device is specially raised, the planting device is forcibly held horizontally and locked.
Simply because the planting device is specially upgraded, compared to the device that automatically locks the planting device, it does not lock in the rolling state, and as a result, the planting device can be placed at the center of gravity of the device. There is no positional fluctuation, allowing stable driving on the road.
