摘要： PURPOSE: To provide the subject washing device so designed that the outer peripheral surface of a revolving drum is furnished with many flexible arms each fitted with a cutting member and, when the corner cutting member at the tip of the arm collides against cultured shellfish(es) conveyed by an endless conveyer as a result of the drum revolution, the arm is flexed backward, thus prevents the overloading on shellfish (es) leading to its (their) breakage or death. CONSTITUTION: Among respective revolving drums 12, a drum 12 equipped on at least one revolving driving shaft is designed to be replaceable. The outer peripheral surface of this drum 12 is furnished with many flexible arms 20. The axial line of the joints 21 of these flexible arms 20 is made parallel with the revolving driving shaft of the drum 12, and all of the flexible arms 20 are raised by the revolution of the drum 12 to effect cutting cultured shellfishes being in conveyance with the endless conveyer.

摘要： PURPOSE:To attempt to improve efficiency of a work and durability of a pallet member and to make mounting and demounting work for a frame easy by performing not to open a hole for a tap on the pallet member and eliminating accordingly works for opening the hole and for cutting the tap. CONSTITUTION:A stud dibble 26 is stood on a pallet member 10 in the neighborhood of a frame 12 for molding a building material. An advancing and retreating bolt 22 is fixed on one end of a clamping fixture 16 and the apex of the bolt 22 is brought into contact with the frame 12. Another end of this clamping fixture 16 is brought into contact with the pallet member 10. At the intermediate part between the bolt 22 position of this clamping fixture 16 and the position where the clamping fixture 16 is brought into contact with the pallet member 10, a fitting hole 32, through which a supporting pole 28 of the stud dibble 26 can be inserted but the head part can not be passed, is formed. The clamping fixture 16 is brought into contact with the head part 30 of the stud dibble 26 and the clamping fixture 16 and the stud dibble 26 are tightly adhered and fixed and the frame 12 is fixed thereby on the pallet member 10.
