Abstract

PURPOSE:To discharge sand and gravel after being screened with good efficiency by a method in which a supply conveyer is set connectedly to muck and also a soil discharge conveyer and a gravel discharge conveyer are set in parallel in relation to the muck. CONSTITUTION:Sand and gravel are charged into a hopper 4 and delivered by a supply conveyer 3. When muck 5 is dropped, finely granulated sand and block-shaped gravel are screened, and the soil is dropped through a soil discharge conveyer 6, a loading conveyer 9, and a chute 10 into a trench A. On the other hand, the gravel is dropped through a gravel discharge conveyer 7 onto the ground's surface and piled up. The conveyer 3 is set connectedly to the muck 5 and a soil discharge conveyer 6 and a gravel discharge conveyer 7 are set in parallel in relation to the muck 5. The soil and the gravel so screened can thus be discharged with good efficiency.
