摘要： PURPOSE: To separate and drain the sewage contained in sand and excrement dreg by providing an insertion port at the upper section of a hopper and a discharge port at the bottom section respectively, providing a water collecting tray between the insertion port and discharge port, and providing a shielding plate inclinatorily forward from the insertion port to the discharge port. CONSTITUTION: The internal space of a hopper 8 is formed into an inverse square pyramid funnel shape, a discharge port 8c is provided at the lowest end, and a conveying mechanism 8e discharging the stored sand and excrement dreg 11 when a gate section 8b is opened is provided. A water collecting tray 9 is provided between an insertion port 8a and the discharge port 8c. A shielding plate 10 is provided inclinatorily forward from the insertion port 8a to discharge port 8c, and passages L1 , L2 guiding the sewage 12 to the water collecting tray 9 are formed between the shielding plate 10 and the inner wall of the hopper 8. The sand and excrement dreg 11 is accumulated and stored by the shielding plate 10. The sewage 12 in the sand is oozed into the passages L1 , L2 , and the sewage 12 overflowing from the tray 9 is drained along a trough section 9a. The sewage 12 can be separated from the sand in the maintenance- free state without causing plugging.

摘要： PROBLEM TO BE SOLVED: To scrape dregs and sediment dropped from the conveyer belt of a steep slope conveyer device, and accumulated, and return them to the carrier side of a conveyer line. SOLUTION: This steep slope conveyer device 1 has a return trough 2 and a scraper 3. The endless belt of the steep slope conveyer device 1 is a corrugate side conveyer 8, and it carries dregs and sediment received from an input port 13 to the carried C side of a conveyer line 7, discharges them through an output port 14, and then, it returns to a return R side, and repeats the circulation. The return trough 2 is provided on the return R side of the conveyer line 7, while the scraper 3 is attached to the corrugate side conveyer 8 without being removed from the output port 14. Then, the scraper 3 scrapes the dregs and the sediment dropped on the return trough 2 on the way of movement, and returns them in the corrugate side conveyer 8.
