Field of the Invention The present invention relates to a work vehicle for removing clogging of a drainage channel by removing deposits such as sediment deposited in the drainage channel. The present invention relates to a work vehicle that can be accurately removed without damaging it.

[0002]

2. Description of the Related Art Conventionally, a drainage channel is formed by a concrete block of U-shape or V-shape in order to introduce or drain water into a field, but most of them are open-top fences. If the drainage channel is left as it is, as shown in Fig. 6, (a) sediment flowing out from the surrounding banks, fields, etc. will settle in the channel, and if it becomes a considerable amount, it will obstruct the flow of water. However, (b) In addition, since the reeds and the weeds that are overgrown in the surrounding area fall over and cover the waterways, the dead grass must be removed once when performing the above-mentioned earth and sand removal work. Moreover, there is a problem that it is difficult to remove the entangled hay.

However, there is no suitable working machine for this. For example, when a hydraulic excavator is used, the bucket is operated in a narrow fence, so that the tip of the bucket hits the bottom wall or side wall of the waterway, and the concrete is broken. -It has a drawback that it breaks the grate wall, and at present, the operator is actually holding the scoop or shovel to manually remove the deposits in the drainage channel.

[0004]

However, such work is very heavy work, and when the fields are spread over a wide area, the working distance becomes long, and there are problems such as lack of manpower and difficulty in working. . The present invention is intended to solve such drawbacks, without destroying the wall surface of the drainage channel,
Moreover, the present invention aims to develop a work machine that does not require manpower and can carry out efficient work.
