Explosive filling device and explosive filling method

Abstract

The invention relates to the technical field of explosive filling, in particular to an explosive filling device and method, and mainly relates to an explosive filling device which comprises a filling bin connected with a filling pipe. The filling pipe comprises an outer sleeve arranged on the upper side of the filling bin and a quantitative column connected into the outer sleeve in a sliding mode in the axial direction, a driving piece used for driving the quantitative column to move is arranged on the filling bin, and a pre-filling cavity is formed between the top of the outer sleeve and the top of the quantitative column. The device has the following effects that space adjustment can be achieved by adjusting the length of the pre-filling cavity, the volume can be calculated through the bottom area and the length, after filling is completed, the quantitative column is separated from the outer sleeve, at the moment, materials can directly fall into the filling bin, filling and dosing can be accurately conducted, and the blasting effect is improved.

Description

technical field [0001] The present application relates to the technical field of explosive loading, and in particular, to an explosive loading device and a loading method. Background technique [0002] In underground construction such as mining and tunnels, blasting operations are often required. Most of the rock drills drill holes of a certain depth, and then fill in explosives. It is easy to deviate from the preset value, resulting in a difference, which directly leads to the inability to effectively guarantee the blasting effect. SUMMARY OF THE INVENTION [0003] In order to improve the precise amount of dosing and improve the blasting effect, the present application provides an explosive charging device and a charging method. [0004] In the first aspect, an explosive filling device provided by the present application adopts the following technical solution: an explosive filling device, including a filling chamber, the filling chamber is connected with a filling pipe,...
