う問題があった。Problems to be Solved by the Invention However, such conventional dredging barges do not have the function of crushing coarse sediments such as large stones and submerged water, so they cannot be used in relatively shallow waters. The problem was that it could only be used in areas with good soil quality. Therefore, when dredging a water bottom with coarse sediments, it was necessary to first remove or crush them before dredging. Further, even if coarse deposits are removed in advance, the work is very large-scale and expensive, and when crushed, the environment may be degraded.
本発明はこのような問題点を解決することのできる土砂
浚渫処理装置を提供することを目的とする。An object of the present invention is to provide an earth and sand dredging device that can solve these problems.

けられたリンク機構駆動９ｉ＠とを有する構成とした。Means for Solving the Problems In order to solve the above problems, the earth and sand dredging and processing equipment of the present invention is provided in the earth and sand dredging hopper of an earth and sand collection bulldozer so as to be rotatable around a horizontal axis and facing each other. The structure includes a pair of left and right screw cutters, a link mechanism for moving the two screws toward and away from each other, and a link mechanism drive 9i@ connected to the link mechanism.

せることなく行える。First, from the state shown in FIG. 6, the hoisting device t11 is operated to let out the hanging wire 12, and the earth and sand collecting bulldozer 13 is lowered to the bottom of the water. At this time, the hose/cable storage conveyor 15 is activated to follow the descent of the earth and sand collecting bulldozer 13 and pull out the earth and sand suction flexible pipe 16, compressed air introduction pipe 17, 18, etc. Then, a jet stream is ejected from the jet ejection nozzle 34, and both screw cutters 35 are rotated to move the piston rod 44 of the compressed air cylinder 43 into and out. Then, link mechanism 3
6, the screw cutter 35 approaches and separates, and the coarse sediment at the bottom of the water is crushed and stirred together with the surrounding hard earth and sand. Therefore, these are immediately sucked from the earth and sand collection bell mouth 33 through the earth and sand suction flexible pipe 16, and guided to the separation tank 8 inside the barge body. During these operations, the earth and sand collecting bulldozer 13 is moved in an appropriate direction by remote control. This enables the crushing and dredging of coarse sediments under adverse conditions such as the ocean or lake bottoms, without harming the environment.
