Embodiment 1

[0035] like figure 1 , image 3 and Figure 4 As shown, according to the length of the explosive package, the distance between adjacent push plates 304 is adjusted. During specific setting, the rotating blocks 307 on both sides of the bottom of the push plate 304 are clamped in the second slot hole of the second mounting block 306, Press the clamping rod 309 inside the short rod 308, so that the clamping rod 309 is clamped in the first slot hole provided at the bottom of the first mounting block 305, and then the pushing plate 304 is fixed. Explosive packs are placed between the first crawler 301 and the second crawler 302, so that the present invention can carry out uninterrupted delivery of explosives according to the actual amount, and solve the problem that due to the deep blasting depth, the delivery distance is long, and the pushing device needs to be withdrawn repeatedly to continue delivery of explosives Time-consuming and labor-intensive problems;

Embodiment 2

[0037] like Figure 1-4 , Figure 6-8As shown, when the outer gun barrel 1 moves in the blasting borehole, the first baffle plate 401, the second baffle plate 402 and the third baffle plate 403 included in the anti-blasting hole blockage unit 4 protect the outer gun barrel 1, while the first The socket block 404 connected to the baffle plate 401 cooperates with the socket hole 405 provided by the second baffle plate 402, so that the first baffle plate 401 and the second baffle plate 402 can push the gravel and earth slag in the blasting borehole to the outside. While on both sides of the gun barrel 1, ensure that the outer gun barrel 1 enters smoothly, the first baffle plate 401 and the second baffle plate 402 will not be opened by gravel and earth slag, and also prevent the outer gun barrel 1 from flowing into the gravel and The earth slag causes blockage, which affects the delivery of the explosive package. When the outer gun barrel 1 moves to the bottom of the blasting bor...

Embodiment 3

[0040] like figure 1 and Figure 5 As shown, the second guide wheel 303 is driven by an external motor, so that the first track 301 and the second track 302 move outside the first guide wheel 201 and the second guide wheel 303, and the first track 301 and the second track 302 drive the push The plate 304 moves to push the explosive package into the blasting borehole. At the same time, the rotating block 307 is released from the second slot hole by the action of the torsion spring 10, and then by the action of the short rod 308, the push plate 304 is turned over and placed in the outer gun barrel. 1 and the inner gun barrel 2 to move in the gap to ensure that the rear push plate 304 can push the explosives smoothly, and at the same time, the roller 5 is affected by the second telescopic rod 501, and the lead wire connected to the explosive package is directional conveyed to ensure that the lead wire will not be twisted. Agglomeration causes breakage, which solves the problem t...

Abstract

The invention discloses a quantitative explosive filling mechanism based on surface mine blasting, relates to the technical field of quantitative explosive filling, and aims to solve the problems that time and labor are wasted due to the fact that an existing device needs to be repeatedly pushed to convey explosive packages, blast holes are prone to being blocked so that filling of the explosive packages fails, and leads are prone to being fractured. The quantitative explosive filling mechanism comprises an outer gun barrel and an inner gun barrel, wherein the inner gun barrel is arranged in the outer gun barrel; first guide wheels are fixed to one end of the inner gun barrel through spot welding, and the first guide wheels are symmetrically arranged; an explosive pushing unit is arranged in the outer gun barrel, and a blast hole blocking prevention unit is arranged at one end of the outer gun barrel; the explosive pushing unit comprises a first crawler belt, a second crawler belt and a second guide wheel; and the first crawler belt and the second crawler belt are slidably connected to the top and the bottom of the inner gun barrel correspondingly. Explosive can be uninterruptedly conveyed according to the actual use amount, time and labor are saved, the problem of blast hole blockage is solved, and lead fracture is prevented.

Description

technical field [0001] The invention relates to the technical field of explosive quantitative loading, in particular to an explosive quantitative loading mechanism based on open-pit mine blasting. Background technique [0002] Blasting technology is widely used nowadays, such as mining stone, transforming terrain, digging tunnel fortifications, excavating roadbed and fortification flat pits, building anti-tank trenches, etc.; it can also be used to destroy solid targets, such as permanent fortifications, bridge piers, concrete pavement, airports Runways, etc., external charge blasting is the blasting that is carried out by disposing the charge outside the target. This blasting method requires more explosives than internal charge blasting. The charge shapes include group charge, in-line charge and shaped charge. , the weight of the charge is calculated and determined according to the geometric size, material strength and configuration of the target. Now the depth of drilling ...
