Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ore mining technology, specifically relating to an anti-clogging material cleaning device for ore shafts. Background Technology
[0002] In some ore shafts, ore extracted through blasting is lowered through the shaft to the bottom, where it is then discharged by loading equipment. A problem arises during the operation of these ore shafts: the discharge opening at the bottom is limited. When the mined ore is large and there are many large ore particles, the friction and compression between them can cause poor discharge, leading to ore accumulation at the bottom of the shaft and blockage, thus affecting its normal operation. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide an anti-clogging material cleaning device for ore shafts, which solves the technical problem of material blockage at the bottom of some existing ore shafts during use.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A device for cleaning up blockages in an ore shaft includes an ore shaft, an anti-blockage cleaning port located at the bottom of the ore shaft, and an anti-blockage cleaning mechanism located at the bottom of the ore shaft and adapted to the anti-blockage cleaning port. The anti-blockage cleaning mechanism includes an operating platform located outside the bottom of the ore shaft, a support mechanism located on the operating platform, a pry bar movably located on the support mechanism and adapted to the anti-blockage cleaning port, and a protective mechanism located on the operating platform and the ore shaft for blocking the anti-blockage cleaning port.
[0006] Furthermore, the support mechanism includes a support fixedly mounted on the operating platform, a movable block rotatably mounted on the support, and a limiting block fixedly mounted on the movable block; the pry bar slides through the limiting block.
[0007] Furthermore, a sliding groove is provided on the limiting block, and a limiting reinforcement block is provided on the limiting block at the top of the sliding groove. The pry bar slides through the sliding groove and is located between the limiting block and the limiting reinforcement block.
[0008] Furthermore, the movable block has blind holes that are adapted to the support, and the top of the support moves through the blind holes.
[0009] Furthermore, a limiting slot is provided on the outer wall of the support in the circumferential direction, and a limiting ring is provided on the outer wall of the movable block to match the limiting slot. The limiting ring is movably embedded in the limiting slot.
[0010] Furthermore, an operating lever is provided on one end of the pry bar, and an operating slot is provided on the operating lever.
[0011] Furthermore, the protective mechanism includes a protective door frame located on the operating platform and the ore shaft and outside the anti-blocking material cleaning port, and two protective door panels that are slidably installed on the protective door frame; the protective door panels are equipped with operating handles.
[0012] Furthermore, a sliding groove is provided on the protective door frame, and the protective door panel is movably inserted into the sliding groove.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This utility model features a pry bar that is movably mounted on an operating platform. Under operator control, it can be extended into or retracted from the ore shaft through an anti-clogging material cleaning port. Once inside the shaft, the pry bar can rotate flexibly on the operating platform, and its extension length is adjustable. This allows the pry bar to be positioned at a stress-prone point in the ore pile, and the operator can press the other end of the pry bar on the operating platform to pry the ore pile, creating an opening in the shaft.

[0029] like Figure 1-9 As shown, the present invention provides an anti-clogging material cleaning device for ore shafts, which solves the technical problem of material blockage at the bottom of some existing ore shafts during use.
[0030] This utility model features a pry bar that is movably mounted on an operating platform. Under operator control, it can be extended into or retracted from the ore shaft through an anti-clogging material cleaning port. Once inside the shaft, the pry bar can rotate flexibly on the operating platform, and its extension length is adjustable. This allows the pry bar to be positioned at a stress-prone point in the ore pile, and the operator can press the other end of the pry bar on the platform to pry the ore pile, creating an opening in the shaft. This allows explosive charges to be dropped into the ore pile, causing it to loosen and break up large pieces of ore, facilitating the discharge of ore from the opening at the bottom of the shaft. This solves the technical problem of material blockage at the bottom of some existing ore shafts, ensuring their normal operation.
[0031] Figure 1 The middle arrow indicates the sliding direction of the pry bar 4 on the limit block 7.
[0032] This utility model includes an ore shaft 1, an anti-clogging material cleaning port 2 opened at the bottom of the ore shaft 1, and an anti-clogging material cleaning mechanism located at the bottom of the ore shaft 1 and adapted to the anti-clogging material cleaning port 2. The anti-clogging material cleaning mechanism includes an operating platform 3 located outside the bottom of the ore shaft 1, a support mechanism located on the operating platform 3, a pry bar 4 movably located on the support mechanism and adapted to the anti-clogging material cleaning port 2, and a protective mechanism located on the operating platform 3 and the ore shaft 1 for blocking the anti-clogging material cleaning port 2.
[0033] The support mechanism includes a support 5 fixedly mounted on the operating platform 3, a movable block 6 rotatably mounted on the support 5, and a limiting block 7 fixedly mounted on the movable block 6; a pry bar 4 is slidably mounted on the limiting block 7. When personnel use the pry bar 4 to pry the ore inside the ore shaft 1, they slide the pry bar 4 on the limiting block 7 towards the anti-blocking material cleaning port 2, allowing the pry bar 4 to extend into the ore shaft 1 through the anti-blocking material cleaning port 2. Then, as needed, the length of the pry bar 4 extending into the ore shaft 1 can be adjusted by sliding the pry bar 4 on the limiting block 7, and the movable block 6 can be rotated to drive the pry bar 4 to rotate synchronously, so as to accurately locate the stress-prone parts of the ore pile inside the ore shaft 1. The purpose of locating the stress-prone parts of the ore pile is to enable personnel to better pry the ore after applying force to the pry bar 4 on the operating platform 3, thereby increasing the spacing between the ore pieces, creating openings, facilitating the placement of explosive charges, and enhancing the detonation effect of the explosive charges.
[0034] After the pry bar 4 is used, slide the pry bar 4 on the limit block 7 to remove the pry bar 4 from the ore shaft 1, and then drop the explosive charge into the ore pile in the ore shaft 1.
[0035] The limiting block 7 has a sliding groove 8, and a limiting reinforcement block 9 is located at the top of the sliding groove 8. The pry bar 4 slides through the sliding groove 8 and is located between the limiting block 7 and the limiting reinforcement block 9. The limiting block 7 and the limiting reinforcement block 9 are integrally connected. The limiting reinforcement block 9 limits the pry bar 4, ensuring that the pry bar 4 is stably installed on the limiting block 7 while strengthening the structure of the limiting block 7. This ensures that when personnel apply force to the pry bar 4, the structure of the limiting block 7 is stable and can withstand the force of the pry bar 4. The sliding groove 8 provides space for the pry bar 4 to slide on the limiting block 7, ensuring the feasibility of extending or retracting the pry bar 4 into or out of the ore shaft 1, as well as adjusting the length of the pry bar 4 extended into the ore shaft 1.
[0036] The movable block 6 has a blind hole 10 that matches the support 5, and the top of the support 5 is movably inserted into the blind hole 10. The outer wall of the support 5 is in clearance fit with the blind hole 10, and the movable block 6 can rotate on the support 5 through the clearance fit between the outer wall of the support 5 and the blind hole 10.
[0037] The outer wall of the support 5 has a circumferentially oriented limiting slot 11, and the outer wall of the movable block 6 is provided with a limiting ring 12 that is adapted to the limiting slot 11. The limiting ring 12 is movably embedded in the limiting slot 11.
[0038] The limiting ring 12 is movably fitted into the limiting slot 11, thus ensuring the stability of the connection between the supporting block 5 and the movable block 6 while ensuring that the movable block 6 can rotate on the supporting block 5.
[0039] The pry bar 4 of this utility model has an operating rod 13 at one end, and the operating rod 13 has an operating slot 14. When personnel apply force to the pry bar 4 on the operating platform 3 to pry the ore inside the ore shaft 1, they can apply force to the pry bar 4 by pressing / lifting the operating rod 13. In use, the operating rod 13 is held with both hands through the operating slot 14 to facilitate better application of force to the operating rod 13.
[0040] The protective mechanism of this utility model includes a protective door frame 15 located on the operating platform 3 and the ore shaft 1 and outside the anti-blocking material cleaning port 2, and two protective door panels 16 slidably mounted on the protective door frame 15; the protective door panels are provided with operating handles 18. The protective door frame 15 is provided with a sliding groove 17, and the protective door panels 16 are movably inserted into the sliding groove 17.
[0041] The protective door frame 15 has a clearance slot 19 that is connected to the anti-blocking material cleaning port 2.
[0042] After dropping the explosive charge into the ore pile inside the ore shaft 1, in order to prevent the broken ore from flying out of the anti-blocking material cleaning port 2 from the ore shaft 1, two protective door panels 16 on the protective door frame 15 can be slid in opposite directions to bring the protective door panels 16 closer to each other until they fit together, thereby blocking the anti-blocking material cleaning port 2.
[0043] Finally, it should be noted that the above embodiments are merely preferred embodiments of this utility model used to illustrate the technical solutions of this utility model, and are not intended to limit it, nor are they intended to limit the patent scope of this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model. That is to say, any changes or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but whose technical problems are still consistent with those of this utility model, should be included within the protection scope of this utility model. In addition, the direct or indirect application of the technical solutions of this utility model to other related technical fields are similarly included within the patent protection scope of this utility model.
