Title:
SEDIMENT CONVEYING DEVICE IN VERTICAL SHAFT
Document Type and Number:
Japanese Patent JP3184943
Kind Code:
B2
Abstract:
PURPOSE: To improve the workability by connecting between the upper and the lower sediments hoppers provided to a vertical shaft, with an upper horizontal screw conveyer, a vertical screw conveyer, and a lower horizontal screw conveyer.
CONSTITUTION: The excavated sediments (a) are put in to a sediments basket 8, and while an arm 13 to which a hoist 11a is installed is erected, the basket 8 is lifted up. Then, a shaft 9 for overturning installed horizontal to the basket 8 is fitted to the recess provided to a hopper 4 for overturning installed to a lower sediments hopper 2, the basket 8 is rotated and overturned, and the sediments (a) are thrown in the hopper 2. Then, the sediments (a) are picked out with a lower screw conveyer 3 and conveyed longitudinally. Furthermore, after the sediments (a) are conveyed vertically with a vertical screw conveyer 34, they are conveyed to an upper horizontal screw conveyer 5, and thrown in to an upper sediments hopper 7 from an exhaust port 6.
