Abstract

PURPOSE:To miniaturize a device and to reduce a manufacturing cost by pulling a horizontal bucket provided with an opening having a cover capable of opening and closing to house sediment, separating a large mass of sediments to keep them into the bucket and absorbing the remainder by a suction pipe to discharge. CONSTITUTION:An opening/closing and moving member 6 mounted to a horizontal bucket 1 is pulled forward by an advancing spring 7, and opening and closing covers 9 and 10 of the front end of the bucket 1 are opened through links 11 and 11. The traction is continuously made in the same state, advancing the bucket 1 to house sediment in a sewage 18, separating a large mass of sediments through a large mass of sediment separating sieve member 5 to keep them into the bucket 1, absorbing the remainder by a suction pipe 3 to discharge. After that, the opening/closing and moving member 6 is pulled backward by a backward spring 8, and the bucket 1 is retreated to a required position after closing the opening and closing covers 9 and 10 by the links 11 and 11. A large mass of sediments kept in the bucket 1 are taken out to remove.
