Description

Technical Field

[0001] The utility model relates to the technical field of deep hole charging, in particular to a charging funnel for deep hole blasting. Background Art

[0002] Because when drilling in rock geology, the drilling platform constantly accumulates scum, resulting in the formation of a trumpet-shaped hole in the borehole, and the borehole wall is very rough. Therefore, when loading explosives into the deep hole, the explosives are easily accumulated around the hole in the ground or deposited and attached to the trumpet-shaped hole, or attached to the hole wall. These explosives are mixed with the filling gravel and soil, and cannot form a drug effect, resulting in a waste of explosives. Moreover, the sticky explosives are not detonated normally during the blasting process, and will remain as blasting residues in the stone after the blasting, leaving a huge safety hazard.

[0003] Chinese patent CN211855092U discloses a device for charging emulsion matrix explosives for open-air medium- and deep-hole blasting. The device includes a funnel body, a discharge port provided at the bottom of the funnel body, and a connecting ring plate provided at the top of the funnel body. A bubble level is removably mounted horizontally on the connecting ring plate. The matrix explosive, which flows out at high speed through a hose, is sprayed directly onto the inner wall of the funnel and then falls through the lower opening of the funnel into the deep hole to be charged and blasted. The bubble level mounted on the funnel allows the funnel to be mounted vertically, ensuring that the emulsion matrix explosive falls completely vertically into the charging position after passing through the funnel, without adhering to the wall of the blasthole again. This prevents waste of explosives and reduces the potential safety risks posed by residual emulsion matrix explosives.

[0004] However, the discharge port at the bottom of the funnel is fixed in length and cannot be extended into the deep hole according to the depth of the deep hole. Although the bubble level can monitor and control the funnel to always be in a vertical state during use, the explosives flowing out of the discharge port will spread. Some of it can fall vertically into the charging position at the bottom of the deep hole, while other parts will still adhere to the wall of the deep hole, and it is impossible to deliver all the explosives into the charging position at the bottom of the deep hole. Therefore, the utility model provides a charging funnel for deep hole blasting to solve the above problems. Utility Model Content
