For example, the rail 50 includes parallel double rails, and the rear dump skip 10 with the self-locking device has four wheels 15 and rolls on the rail 50 by the four wheels 15.
The rear dump inclined shaft skip 10 with the self-locking device in the embodiment comprises a skip box 11, a discharge gate 16 and a locking device 30. The discharge opening 18 of the hopper 11 is located at the rear thereof, and the included angle H1 between the floor 12 of the hopper 11 and the plane of the discharge opening 18 is an acute angle. Optionally, the angle H1 between the floor 12 of hopper box 11 and the plane of its discharge opening 18 is complementary to the slant angle H2. In the scheme, the plane of the discharge opening 18 is a vertical plane, and the bottom plate 12 is obliquely arranged and is basically parallel to the track 50; in this way, when the discharge gate 16 is opened, the material in the hopper case 11 can fall down along the bottom plate 12 under its own weight to be discharged.
The discharge gate 16 in this embodiment is arranged vertically. The discharge gate 16 is rotatably connected at its upper edge to the rear of the hopper 11 and is located at a position closing a discharge opening 18 at the rear of the hopper 11 in its naturally drooping state. Optionally, to improve the ability of the discharge gate 16 to close the discharge opening 18, in this embodiment, the hopper 11 further includes a rim plate 14 located at the plane of the discharge opening 18 and surrounding the periphery of the discharge opening 18. The discharge gate 16 in its naturally sagging state abuts against the edge panel 14.
Alternatively, the hopper case 11 in this embodiment includes a bottom plate 12 and side plates 13 connecting both sides of the bottom plate 12, rear edges of the side plates 13 being vertical, and a discharge opening 18 being defined between rear edges of the two side plates 13. And the discharge gate 16 can be hingedly connected at its upper side to the upper end of the rear edges of the two side plates 13.
The locking device 30 is mounted to the floor 12 of the hopper 11 and includes a drive structure and a locking buckle 32. The driving structure is in transmission connection with the locking buckle 32 and can drive the locking buckle 32 to move to a first position Y1 for locking the discharge gate 16 in the hopper box 11 or a second position Y2 for unlocking the discharge gate 16. Optionally, a wedge block 17 is arranged at the lower edge of the discharge gate 16, a through opening 19 is arranged on the edge plate 14, and the locking buckle 32 penetrates through the through opening 19 and can be driven to press or leave a lower wedge surface P1 of the wedge block 17.
In this embodiment, the locking buckle 32 has a front end 32a bent upward for being hingedly connected to the middle portion 32b of the bottom plate 12 and a rear end 32c for being connected to the telescopic member 31 as a driving structure, and the locking buckle 32 can be rotated by the telescopic member 31 to a position where the front end 32a of the hook thereof locks or unlocks the discharge gate 16. Optionally, the telescoping member 31 is connected to the rear end 32c of the locking buckle 32 by a link 34. The telescopic member 31 in this embodiment is a conventional worm and gear elevator, and the driving worm 31a is connected to a hand-operated wheel 35 for rotating the driving worm 31a to further drive the telescopic rod 31b of the telescopic member 31 to extend and retract.
