Abstract

PURPOSE:To achieve power conservation by simplifying installation and manipulation, by simultaneously removing trash and sand in a washing tank by attaching a large number of flights with rakes to one set of two main chains each arranged in an endless form. CONSTITUTION:A screen 3 for inhibiting the passage of trash and a sand scraping part 4 for scraping sand accumulated at the bottom part of a washing tank 1 and performing drainage are provided in the washing tank 1 and one set of two main chains 6 is arranged along the back surface of the screen 3 and the upper surface of the sand scraping part 4 in an endless form so as to be passed upwardly from below. A large number of flights with rakes each consisting of a comb shaped rake part 7a and a shallow bucket shaped flight part 7b are attached to the main chains 6. When the chains 6 are driven in the arrow direction 14, the rake part 7a is protruded to the front surface of the screen 3 from the back surface thereof and scoops up trash to take out the same to a delivering conveyor 12 while the flight part 7b scrapes up the sand on the tank bottom part to take out the same to a delivering conveyor 13.
