Claims

[Scope of utility model registration request]

An extension plate 15 is swingably attached to at least one side of the ground plate 14 attached to the traveling vehicle 1.
It is said that the posture can be changed freely between a grounding posture in which the left and right width of the ground is extended, and a separation posture in which it is separated from the ground.
A spring 21 is stretched between the ground plate 14 and the extension plate 15 so as to swing together with the extension plate 15, and the swing of the spring 21 causes the extension plate 15 to touch the ground when the extension plate 15 is located closer to the ground contact posture than a certain position. In the spring 21, the holder 22 of the spring 21 is biased to swing in the direction of the spring 21, and is urged to swing in the direction of the separation posture when the spring is located on the side of the separation posture from a certain position.
A rope body 25 is attached to the ground plate 14 so as to swing in accordance with the swing of the spring 21, and can be pulled and operated by an operator riding on the traveling vehicle 1. The cable body 25 is connected to the extension plate 15 via a guide body 27. , the guide body 27 is attached to the ground plate 14 so as to be able to freely vibrate, and the guide body 27 moves the cable body 2 so that the tension of the cable body 25 can swing the extension plate 15 in the separating direction.
The position can be freely changed between a first guiding position in which the cable 5 is guided and a second guiding position in which the cable 25 is guided so that the extension plate 15 can be swung in the ground contact direction by the tension of the cable 25. At a position where the extension plate 15 has swung toward the separation posture beyond the above-mentioned certain position, the posture is changed from the first guiding posture to the second guiding posture, and at a position where the extension plate 15 has swung beyond the certain position toward the grounding posture. The guide body 27 is attached to the holding body so that the posture is changed from the second guiding posture to the first guiding posture.
2. A grounding plate extension device for a grounding work machine, characterized in that the grounding plate extension device is interlocked with the grounding work machine.
