[Detailed Description of the Invention] This invention relates to a dredging device, and more particularly to a portable and simple dredging device that can suck up dredged soil straight upward from the water bottom.

Traditionally, dredging of lakes, marshes, rivers, etc. has been carried out by submerging a pipe with a weight attached to the end and using a suction pump to suck up sediment from the bottom, or by using a submersible pump. The pipe that guides the sand flow diagonally enters the water from its tip, and therefore, when the pipe is introduced from a barge, the dredging point is a remote point far from the barge, and the dredging can only be carried out roughly to the desired location. There wasn't.

このため特にダム湖などのように特定の個所の浚渫を行
なおうとする場合に作業に手間どり、またややもすると

This made dredging work particularly difficult when attempting to dredge a specific area, such as a dam lake, and there was also the risk that the tip of the pipe would become buried in the sediment at the bottom, making suction undesirable.

After this, the main suction pump that also serves as a weight body and the high-pressure water injection pump 1
By activating the pump 5 at the same time as the 0 operation, the target point can be effectively dredged efficiently, and the dust catching depth of the weight body 9 can be changed with the expansion and contraction of the water pipe 8 according to changes in water depth. However, if the winch 2 is set free, a suitable gripping seat weight adjusted by the counterweight 14 is always acting, so continuous dredging can be carried out automatically without any manual intervention.
