摘要

The trough has a vat (10) provided with a drain opening (1) in its low part for draining the vat. A rubber stopper (2) is configured for blocking the opening, and an operation device operates the stopper between opening position and closing position of the stopper. The operation of the stopper toward the opening position of the stopper causes translation toward the interior of the vat. The operation device is placed outside the vat so as to carry out the operation without placing a hand in the vat. A locking unit locks the stopper in opening position of the stopper.
