A device for removing tree roots from blast holes in dangerous rock masses

Abstract

The invention discloses a device for removing roots from blast holes in dangerous rock mass blasting, belonging to the technical field of blasting engineering. The two ends of the fixed seat are stored in the chute opened by the support rods on both sides of the fixed bracket, the fixed seat is movably connected with the fixed bracket, and there is a clamping mechanism between the fixed seat and the fixed bracket for fixing The fixed seat and the fixed bracket, the top of the cutting knife is provided with a connecting rod, the top of the connecting rod is provided with a force plate, the connecting rod and the force plate are detachably connected, and the bottom end of the force plate and the top of the fixed seat are provided with There is a first spring, and the top of the fixed seat is provided with a limit plate to prevent the cutting knife from coming out of the fixed seat; the connecting rod at the top of the cutting knife can be split into multiple pieces, and the connecting rods are connected by threads. In the fixed seat, a tool is used to tap the chopper to cut off the root of the tree, which is convenient to operate and improves the operation safety.

Description

technical field [0001] The invention belongs to the technical field of blasting engineering, and in particular relates to a device for removing roots from blast holes of dangerous rock masses. Background technique [0002] Dangerous rock mass means that when the rock mass is suspended and has obvious cracks, there is a risk of collapse at any time, so it has a major safety hazard. Due to the complex terrain of the dangerous rock mass, it is mostly on uneven slopes and cliffs. Therefore, the dangerous rock mass is usually demolished by blasting. Since there are usually trees, vines and other plants growing around the dangerous rock mass and on the body, the roots of the plants will drill into the cracks of the dangerous rock mass, and the roots will affect the drilling. , and when the emulsion explosive is loaded into the blast hole, it will be stuck, and the explosive can not be filled at the bottom of the hole, which will seriously affect the blasting effect. SUMMARY OF T...

[0002] Dangerous rock mass means that when the rock mass is suspended and has obvious cracks, there is a risk of collapse at any time, so it has a major safety hazard. Because the terrain of the dangerous rock mass is relatively complicated, most of them are on uneven slopes and cliffs. Therefore, blasting is usually used to remove the dangerous rock mass. Since trees, vines and other plants usually grow around the dangerous rock mass and on the body, the roots of the plants will drill into the cracks of the dangerous rock mass, and the tree roots will affect the drilling. , and when the emulsion explosive is loaded into the blast hole, it will be stuck, and the explosive will not be filled at the bottom of the hole, which will seriously affect the blasting effect. Therefore, we propose a device for removing tree roots in the blast hole of dangerous rock
