Description

Technical Field

[0001] The utility model relates to the technical field of blasting devices, in particular to a mixed emulsion explosive filling device. Background Art

[0002] Mixed emulsion explosives are commonly used in open-pit mining and infrastructure blasting due to their high stability and safety. Emulsion explosives are usually mixed at the blasting site and then poured into the blasthole. Since blastholes are prone to cracks during mining, to prevent the mixed emulsion explosives from escaping through the cracks, it is usually necessary to put an anti-seepage bag in the blasthole during filling. To facilitate filling, people have designed some tools for fixing the anti-seepage bag. For example, Chinese patent application No. 202320619664.0 discloses an auxiliary device for filling on-site mixed emulsion explosives. The device includes a main sleeve that can be inserted into the blasthole. The main sleeve is provided with an anti-seepage bag for filling the emulsion explosive. The bag opening of the anti-seepage bag is folded back and attached to the outside of the main sleeve. A fixing portion is provided on the outer surface of the bag opening. By locking the fixing portion, the bag opening is tightly attached to the outside of the main sleeve. The main sleeve is externally connected to a limiting portion to prevent the main sleeve from slipping into the blasthole. The device is formed by folding the bag opening of the anti-seepage bag in reverse and then fixing the anti-seepage bag on the main sleeve through the fixing part. Although this solution can fix the anti-seepage bag well, it requires the use of clamps, bolts and nuts and auxiliary tools such as wrenches to tighten the nuts. There are many blast holes during blasting, and the use of this device will reduce work efficiency. In addition, the caliber of the upper part of the main sleeve is small, which is not suitable for filling mixed emulsion explosives. Therefore, a mixed emulsion explosive filling device is needed, which can quickly and conveniently fix the upper part of the anti-seepage bag, facilitate filling of mixed emulsion explosives, improve work efficiency, and improve the convenience of filling at the funnel part on the upper part of the sleeve.

[0020] like Figures 1 to 4 As shown, an embodiment of the present invention provides a mixed emulsion explosive filling device, comprising: a sleeve 1, a funnel 2, and an anti-seepage bag 3. The sleeve 1 is mounted on the upper part of the blasthole, and an annular slot 4 is provided on the outer side of the upper part of the sleeve 1. One end of the anti-seepage bag 3 is knotted, and the other end of the anti-seepage bag 3 passes through the sleeve 1 from bottom to top, and the mouth of the anti-seepage bag 3 is folded over; an insertion portion 5 is provided at the lower part of the funnel 2, and the insertion portion 5 is inserted into the annular slot 4 from top to bottom, and the mouth of the anti-seepage bag 3 is fixed in the gap between the insertion portion 5 and the annular slot 4; a limit block 6 is hingedly installed on the outer side of the lower part of the sleeve 1, and the sleeve 1 is mounted on the upper part of the blasthole through the limit block 6.

[0021] When loading mixed emulsion explosives, tie a knot at one end of the anti-seepage bag 3 and put it into the blasthole. The other end of the anti-seepage bag 3 passes through the sleeve 1 from bottom to top, and then the mouth of the anti-seepage bag 3 is folded. Then, the insertion part 5 at the lower part of the funnel 2 drives the anti-seepage bag 3 to be inserted into the annular slot 4. After the insertion part 5 is inserted into the annular slot 4 from top to bottom, the rear part of the anti-seepage bag 3 is bent multiple times, so that it is fixed on the upper part of the sleeve 1. The mixed emulsion explosives are poured into the anti-seepage bag 3 through the funnel 2 to improve the filling efficiency. After the filling is completed, the worker steps on the limit block 6 with his foot, and then pulls up the funnel 2 to separate the funnel 2 from the sleeve 1, pulls the insertion part 5 out of the annular slot 4, thereby loosening the upper part of the anti-seepage bag 3 and completing the charging operation of the blasthole.

[0022] Specifically, a connecting portion 7 is provided at the lower part of the sleeve 1, and one end of the limit block 6 is hinged to the connecting portion 7. When the limit block 6 is rotated to be perpendicular to the sleeve 1, the upper end surface of the limit block 6 is tightly attached to the inner side of the connecting portion 7. The limit block 6 can be mounted on the blast hole to prevent the sleeve 1 from falling into the blast hole. The limit block 6 is limited by the connecting portion 7 so that the limit block 6 is supported by the connecting portion 7 after being unfolded, so that the limit block 6 remains in the unfolded state, thereby supporting the sleeve 1.

[0023] In a preferred embodiment, Figure 4 As shown, a first protrusion 8 is provided at one end of the limit block 6, and a first limiting groove 9 is provided on the inner side of the connecting portion 7 and the outer side of the sleeve 1. When the limit block 6 is rotated to be perpendicular to the sleeve 1, the first protrusion 8 is connected to the first limiting groove 9 on the inner side of the connecting portion 7. When the limit block 6 is rotated to be parallel to the sleeve 1, the first protrusion 8 is connected to the first limiting groove 9 on the outer side of the sleeve 1. The limit block 6 is made of plastic material and can undergo partial deformation. Damping is provided by the first protrusion 8, so that the limit block 6 can provide damping in the expanded state and the retracted state, so that the limit block 6 can maintain two states.

[0024] Specifically, if Figure 3 As shown, the insertion part 5 is provided with a second protrusion 10 on both sides inside and outside, and the annular slot 4 is provided with a second limiting groove 11 on the inner side. When the insertion part 5 is inserted into the annular slot 4, the second protrusion 10 is connected to the second limiting groove 11. The second protrusion 10 and the second limiting groove 11 can provide damping, so that the insertion part 5 is not easy to loosen after being inserted into the annular slot 4, which facilitates fixing the anti-seepage bag 3 on the sleeve 1.

[0025] In a specific embodiment, an extension portion 12 is provided in the middle of the funnel 2, and the extension portion 12 extends 3 cm to 5 cm into the sleeve 1, so that the mixed emulsion explosive can be introduced into the sleeve 1 through the extension portion 12 after passing through the funnel 2, which facilitates the loading of the mixed emulsion explosive.

[0026] Preferably, the upper portion of the annular slot 4 and the lower portion of the inserting portion 5 are both provided with smooth chamfers to avoid sharp corners that may cause the impermeable bag 3 to be scratched.

[0027] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
