Excavation earth and sand discharge device

摘要

PURPOSE:To improve the working efficiency by installing the first conveyor equipped with an extension mechanism arranged on a supporting base, second conveyor consisting of a horizontal part and a vertical part, and a soil/sand piling-up device equipped with an excavated soil/sand pulverizing mechanism and a mobile mechanism. CONSTITUTION:An excavated soil/sand discharging device is constituted of a supporting base 10, an overhand part 12, a first conveyor 20, a second conveyor 30 consisting of a horizontal part 30a and a vertical part 30b, and a soil/sand piling up device 40 consisting of a sand/soil pulverizing mechanism 41 and a mobile mechanism 42. The excavated soil and sand are piled onto the second conveyor 30 from an excavator 90 by the soil/sand piling-up device 40, and transported upward, passing through the vertical part 30b, and then transferred onto the first conveyor 20, and discharged onto the ground surface 1. When the excavation depth increases, the device 40 at the lower edge of the vertical part 30b is lowered. When the excavation area is spread, the first and second conveyors 20 and 30 are extended towards the overhang part 12. Therefore, the working efficiency can be improved.
