Description

Technical Field

[0001] This utility model relates to the field of mining technology, and in particular to an anti-blocking device for blast holes in open-pit mines. Background Technology

[0002] In open-pit mining, drilling, blasting, loading, and transportation are the main processes. Drilling is the primary process, and its hole formation rate is an important economic indicator for the mine, directly affecting subsequent processes such as blasting, loading, and transportation. Due to geological conditions, the diversity of ores and rocks, and the conditions of the mining site, drilled blast holes are sometimes blocked by large rocks or rock powder falling from the hole opening or around the hole wall, resulting in blocked or abandoned holes, making it impossible to carry out explosive loading. A blast hole anti-blocking device for open-pit mines, Chinese patent application number CN202121957421.5, uses a plug body inserted into the blast hole to effectively protect the blast hole and prevent blockage. The cap and plug body are an integral structure, with the cap being a circular plate structure and the plug body being a cylindrical structure. The diameter of the cap is larger than the diameter of the plug body, thus effectively covering the blast hole and preventing debris from entering. However, the plug body in the above device only relies on itself to be engaged inside the blast hole, making it easy to accidentally remove the plug body from the blast hole, thereby losing the sealing effect and causing the blast hole to become blocked. Utility Model Content

[0024] Example 1

[0025] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides an anti-blocking device for blast holes in open-pit mines. The anti-blocking device for blast holes in open-pit mines includes a blocking component 100 and a limiting component 200. The blocking component 100 is used to block the blast hole, and the limiting component 200 is used to limit and fix the blocking component 100.

[0026] The sealing assembly 100 includes an embolization body 101, a limiting cap 102, a vent 103, and a dustproof component 104. The limiting cap 102 is disposed on the upper side of the embolization body 101, the vent 103 is opened inside the embolization body 101, and the dustproof component 104 is disposed on the upper side of the limiting cap 102.

[0027] The plug body 101 is inserted into the borehole to seal it. The limiting cap 102 limits the plug body 101 to the outside of the borehole. The vent 103 is used to maintain air circulation inside the borehole, and the dustproof part 104 is used to prevent dust from falling into the borehole.

[0028] The limiting component 200 is disposed around the upper part of the embolization body 101 and includes a fixing sleeve 201, a restraint member 202 and an adjusting member 203.

[0029] The restraint 202 moves inside the fixed sleeve 201, and the tightness of the restraint 202 is adjusted by the adjusting member 203, thereby fixing the plug body 101 inside the borehole and preventing the plug body 101 from loosening and falling off.

[0030] Example 2

[0031] Reference Figure 1 , Figure 2 and Figure 3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0032] Specifically, the limiting cover 102 includes a cover body 102a and a handle 102b. The cover body 102a is fixed to the upper side of the plug body 101, and the handle 102b is fixed to the upper side of the cover body 102a.

[0033] The cover 102a limits the plug body 101 to the outside of the borehole, and the handle 102b facilitates the removal of the plug body 101.

[0034] Specifically, the dustproof component 104 includes a mounting frame 104a and a filter screen 104b, with the filter screen 104b fixed inside the mounting frame 104a.

[0035] The filter screen 104b is used to protect the through hole of the cover 102a, so as to prevent dust and other debris from falling into the borehole and causing pollution.

[0036] Specifically, the dustproof component 104 also includes a threaded sleeve 104c, which is fixed to the lower side of the mounting frame 104a, and the limit cover 102 has a threaded hole that matches the threaded sleeve 104c inside.

[0037] The threaded sleeve 104c is threaded into the inside of the threaded hole, which facilitates the installation of the mounting frame 104a and the filter screen 104b on the cover 102a.

[0038] Example 3

[0039] Reference Figure 4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0040] Specifically, the fixing sleeve 201 includes a first fixing block 201a and a second fixing block 201b. The first fixing block 201a is fixed to the lower side of the cover 102a, and the second fixing block 201b is fixed to the outside of the first fixing block 201a.

[0041] Two first fixing blocks 201a are provided and are symmetrically fixedly connected to the lower side of the cover 102a.

[0042] Specifically, the restraint 202 includes a limiting band 202a and teeth 202b. One end of the limiting band 202a is located on the left side of the first fixing block 201a, and the other end of the limiting band 202a passes through another first fixing block 201a. Teeth 202b are fixed to the outer side of the end of the limiting band 202a and inserted into the second fixing block 201b.

[0043] One end of the limiting band 202a is fixedly connected to the outside of a first fixing block 201a, the rest of the limiting band 202a is inserted into the inside of another first fixing block 201a, and the teeth 202b are fixed to the rear part of the limiting band 202a and are inserted into the inside of the second fixing block 201b.

[0044] Specifically, the adjusting component 203 includes a housing 203a and a gear 203b. The housing 203a is fixed to the outside of the second fixing block 201b, and the gear 203b is rotatably connected to the inside of the housing 203a.

[0045] Gear 203b rotates inside housing 203a and meshes with tooth 202b. The rotation of gear 203b drives tooth 202b and limiting band 202a to move inside second fixed block 201b, thereby binding and tightening limiting band 202a to the outside of the blast hole.

[0046] Specifically, the adjusting component 203 also includes a rotating rod 203c and a torsion bar 203d. The rotating rod 203c passes through the housing 203a and is fixed at the center of the gear 203b to drive the gear 203b to rotate. The torsion bar 203d is fixed at the top of the rotating rod 203c.

[0047] The torsion bar 203d is used to rotate the rotating rod 203c, which in turn drives the gear 203b to rotate, thereby tightening the limit band 202a.

[0048] In use, the plug body 101 is inserted into the inside of the borehole, and the limiting band 202a is fitted onto the outside of the borehole. The torsion bar 203d rotates the rotating rod 203c, which drives the gear 203b to rotate. The gear 203b rotates inside the housing 203a and meshes with the teeth 202b. The rotation of the gear 203b drives the teeth 202b and the limiting band 202a to move inside the second fixing block 201b, thereby binding and tightening the limiting band 202a on the outside of the borehole, preventing the plug body 101 from loosening and falling off, which would affect the sealing effect of the borehole. The filter screen 104b protects the through hole of the cover body 102a, preventing dust and other debris from falling into the borehole and causing pollution.
