[0002] At present, the hoisting of ore and waste rock in underground mines is mainly through the ore pass system. Generally, an ore discharge machine is arranged at the bottom of the main ore pass for the transfer and discharge of ore and waste rock. Due to the long-term impact of ore and waste rock, the ore discharge machine needs to be repaired, maintained or replaced. Considering that personnel need to stand at the ore pass opening for operation, generally, the ore and waste rock in the ore pass are emptied, and then protection is made at the lower opening of the ore pass to play a protective role. However, there are many uncertain factors in the maintenance of the ore discharge machine. Sometimes, it is impossible to empty the ore and waste rock in the main ore pass, or after the ore pass is emptied, it is impossible to confirm the loose rock on the well wall, etc. The safety of personnel cannot be guaranteed during the protection or operation at the lower opening of the vibrating feeder chamber.

[0020] The following further describes in detail the specific embodiments of the present invention in conjunction with the attached Figures 1-4 drawings.

[0021] As Figures 1-4As shown in the figure, a safety protection structure for preventing blockage of the ore discharge hopper in the main ore pass of the utility model includes an ore discharge guiding hopper 20 installed on the vibrating feeder chamber 10. There is an ore leakage opening 21 between the ore discharge guiding hopper 20 and the vibrating feeder chamber 10, and the ore discharge guiding hopper 20 is provided with a first protection device 30 and a second protection device 40;

[0022] The first protection device 30:

[0023] It includes a number of support members 31. The number of support members 31 penetrates into the rear inclined wall of the ore discharge guiding hopper 20 from the side in a movable manner to form a pipe shed structure. The setting of the pipe shed structure can support the ore and waste rocks in the main ore pass to prevent the waste ore from falling into the vibrating feeder chamber 10 and hitting the operating personnel, playing the first protection role.

[0024] The second protection device 40:

[0025] It is set at a position 800 mm below the first protection device 30 and includes an ore leakage opening baffle 41 and an ore leakage opening baffle driving mechanism 42. The ore leakage opening baffle 41 is symmetrically arranged on both sides of the ore leakage opening 21. The ore leakage opening baffle driving mechanism 42 is arranged on the vibrating feeder chamber 10 to drive the two ore leakage opening baffles 41 to approach or move away from each other. When the two ore leakage opening baffles 41 approach each other, the ore leakage opening 21 is closed. When the two ore leakage opening baffles 41 move away from each other, the ore leakage opening 21 is opened. After the first protection is formed, the two ore leakage opening baffles 41 are pushed towards the inner side of the ore discharge guiding hopper 20 through the ore leakage opening baffle driving mechanism 42 until the ore leakage opening 21 is blocked to form the second protection function, which can further prevent small crushed stones from falling into the vibrating feeder chamber 10.

[0026] In order to increase the connection strength between the support member 31 and the ore discharge guiding hopper 20, a number of reserved pipes 32 are fixed on the bottom side of the ore discharge guiding hopper 20. The support member 31 is movably connected in the reserved pipe 32. Through the setting of the reserved pipe 32, one end of the support member 31 is inserted into the reserved pipe 32, and the other end abuts against the rear inclined wall of the ore discharge guiding hopper 20 for limit support, which is convenient for quick positioning.

[0027] In some embodiments, the support member 31 is a φ32 mm deformed steel bar, the reserved pipe 32 is a φ60 mm steel pipe, the distance between the steel pipes is 250 mm, and the steel pipe is fixedly welded to the ore discharge guiding hopper 20.

[0028] In some embodiments, the ore leakage opening baffle 41 is a steel plate with a length of 1900, a width of 1000, and a thickness of 10 mm.

[0029] In some embodiments, the ore leakage opening baffle driving mechanism 42 is a hydraulic telescopic rod. The hydraulic telescopic rods are symmetrically arranged on both sides of the top of the vibrating feeder chamber 10, and the heads of the hydraulic telescopic rods are fixedly connected to the ore leakage opening baffle 41.

[0030] Rubber sheets 43 are fixed on the opposite surfaces of the two ore leakage baffle plates 41 to prevent dust and the like from entering the vibrating feeder chamber 10.

[0031] In the present utility model, by installing the first protection device 30 and the second protection device 40 on the ore discharge guiding hopper 20, a double safety protection is formed. The first protection device 30 uses the movable support member 31 to form a pipe shed structure inside the ore discharge guiding hopper 20 to support and hold the ore waste rock to play the first protection role. The second protection device 40 drives the ore leakage baffle plate 41 to block the ore leakage opening 21 through the hydraulic telescopic rod, further ensuring the safe operation of the personnel in the vibrating feeder chamber 10.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
