    • PROBLEM TO BE SOLVED: To completely prevent leakage of sludge and sewage from a mating part of an opening surface of left-right buckets.
      SOLUTION: In this clamshell bucket, the left bucket 4 and the right bucket 5 are rotatably arranged around support shafts 6 and 7 of a lower end part of left-right arms 2 and 3 having the upper end journaled to a machine body 1, and the mutual inside edges of the opening surface of the left-right buckets 4 and 5 are joined by a pivot shaft 8, and sediment of the sea bottom is dredged by opening-closing and moving the left-right buckets 4 and 5 by liftably operating its pivot shaft 8 by an opening-closing wire 11 of a crane. A part except for the opening surface of the left-right buckets 4 and 5 is formed into a sealed structure. Sealing packing 12 is installed in the mating part of the opening surface of the left-right buckets 4 and 5, and an air bleeding port 13 and an air bleeding door 14 for opening and closing this port are arranged on a back face of the left-right buckets 4 and 5. The mating part of its opening surface is made watertight when closing the left-right buckets 4 and 5 by grinding and processing the mating part of the opening surface of the left-right buckets 4 and 5.

    • PURPOSE:To remarkably reduce noise by using a system in which a nearly L- shaped operation bar having a sideward end projected into the pathway of a crown body is provided in such a way as to cause striking with a head assembly within the crown body. CONSTITUTION:When closed shell is pulled up, a crown pole 8 is so pushed by the lower end of an operation bar 26 pressed downwardly by a tension spring 21 that it is not projected into a pathway 4. Accordingly, the head cap nut 9 of the head assembly 2 can pass without being caught on the crown pole 8. When a rope is further raised, the head of the head cap nut 9 comes into contact with the side end of the operation bar 20, the operation bar 20 is pushed up, and the crown pole 8 is released. The crown pole 8 is thus inclined under its own weight and the jaw of the head nut 9 is contacted withthe tip of the crown pole 8.
    • 目的:通过使用这样的系统来显着降低噪音,其中具有投影到冠体的路径中的侧向端的近似L形的操作杆以使头部组件在冠体内部引起打击的方式设置。 构成:当闭合的壳体被拉起时,冠杆8被由拉伸弹簧21向下压的操作杆26的下端推动,使其不会突出到通路4中。因此,头盖螺母9 头部组件2可以通过而不被卡在冠杆8上。当绳索进一步升高时,头帽螺母9的头部与操作杆20的侧端接触,将操作杆20向上推 并且顶杆8被释放。 因此,冠杆8在其自重下倾斜并且头螺母9的钳口与冠杆8的尖端接触。
