PURPOSE: To improve the scraping efficiency of the load in a hold by storing a vertical conveyor in a rotatable column, assembling an L-shaped bucket chain excavator to a bucket descent side, and adjusting the length of the bottom section of the excavator with a hydraulic cylinder.
CONSTITUTION: A column 6 storing a vertical conveyor 14 is rotatably fitted to a support frame. An L-shaped bucket chain excavator 8 is assembled and fitted to the bucket descent side of the vertical conveyor 14. Two moving arms 19, 20 constituting an L-shaped bottom section are link-connected to a fixed arm 21 at the lower end of the column 6, a hydraulic cylinder 23 is fitted to a projection 19a at the middle of the moving arm 19, and the projection 20a of the arm 20 is fitted to the arm 21 with a link 25. The length and height of the bottom section can be extended or shrunk by the extension or shrinkage of the hydraulic cylinder 23, and the arm 20 can be horizontally extended or shrunk along a guide rail 31. The scraping efficiency of the load in a hold can be improved.
