[0006] Furthermore, the skip ore transporting device comprises a skip, a pulling wire rope and a hoist.

[0007] Furthermore, a wire guide wheel is provided at the outlet of the inclined shaft.

[0008] Furthermore, gates are provided at the exits of the temporary ore storage bin and the ore unloading bin.

[0009] Furthermore, a belt conveyor is provided below the outlet of the ore unloading bin.

[0010] Furthermore, the temporary ore storage bin and the ore unloading bin are both provided with material level detection devices.

[0011] An ore lifting method for the above-mentioned automatic ore lifting device in an inclined shaft, wherein the skip is pulled and moved to a temporary ore storage bin where the ore needs to be transferred by a hoist, the moving distance of the skip is accurately measured by a temporary encoder, and the travel path of the skip is accurately controlled by a stroke correction switch; the gate of the temporary ore storage bin is opened, and the ore in the temporary ore storage bin is unloaded into the skip, and the storage status of the skip is fed back by a material level detection device. After the skip is loaded to a set material level, the gate of the temporary ore storage bin is closed; the skip is pulled and moved to the ore unloading bin by a hoist, and the ore is automatically unloaded into the ore unloading bin when the skip passes through a ore unloading curved track.

[0012] Beneficial effects of the present invention:

[0013] The present application discloses an automatic ore lifting device and method for an inclined shaft, the device comprises a skip track arranged along the inclined shaft, a plurality of temporary ore storage bins arranged at intervals along the skip track, an ore unloading bin arranged at the exit of the inclined shaft, and a skip ore transport device for ore transportation, wherein an ore unloading curved track is arranged at the position of the inclined shaft track corresponding to the ore unloading bin. The device and method of the present application realizes mining and ore transportation at the same time, thereby improving mining efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] Figure 1 It is a structural schematic diagram of a preferred embodiment of the present invention. DETAILED DESCRIPTION

[0016] The present invention is further described in detail below through the accompanying drawings and embodiments. Through these descriptions, the characteristics and advantages of the present invention will become clearer and more specific. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0017] like Figure 1 As shown, this embodiment discloses an automatic ore lifting device in an inclined shaft, including a skip track arranged along the inclined shaft, a plurality of temporary ore storage bins 10 arranged at intervals along the skip track, an ore unloading bin 6 arranged at the exit of the inclined shaft, and a skip ore transport device for ore transportation, wherein a curved ore unloading track 5 is arranged at the position of the inclined shaft track corresponding to the ore unloading bin. The skip ore transport device includes a skip 4, a pulling wire rope 3 and a hoist 1. A wire guide wheel 2 is arranged at the exit of the inclined shaft. Gates 7 are arranged at the exits of the temporary ore storage bin and the ore unloading bin. A belt conveyor 8 is arranged below the exit of the ore unloading bin. By opening the gate of the ore unloading bin, the ore in the ore unloading bin can be transported by the belt conveyor. The temporary ore storage bin and the ore unloading bin are both provided with a material level detection device 9.

[0018] The present embodiment also discloses a feeding method for the above-mentioned inclined shaft automatic ore lifting device, when the left feeding chute is feeding and storing materials and the right feeding chute is feeding materials into the furnace, the left gate is closed, the right gate is opened, the movable flap opens the left feeding chute, and at the same time, the right feeding chute is closed, and the falling materials at the hopper mouth flow into the left feeding chute for storage, and at the same time, the materials in the right feeding chute flow into the furnace body for smelting; when the right feeding chute is feeding and storing materials and the left feeding chute is feeding materials into the furnace, the left gate is opened, the right gate is closed, the movable flap closes the left feeding chute, and at the same time, the right feeding chute is opened, and the falling materials at the hopper mouth flow into the right feeding chute for storage, and at the same time, the materials in the left feeding chute flow into the furnace body for smelting.

[0019] In summary, by temporarily storing ore in a temporary ore storage bin and then automatically transporting the ore through a skip transport device, mining and ore transportation can be carried out simultaneously, thereby improving mining efficiency.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it.
