Description

Technical Field

[0001] The utility model relates to the technical field of drilling, in particular to an ore drilling auxiliary device and drilling equipment. Background Art

[0002] Drilling operations usually include three key actions: the propulsion mechanism drives the rotary mechanism to move linearly along the propulsion beam to ensure that the impactor and drill bit always reach the bottom of the hole, which is used to transmit the impact force to the rock; the drill rod is installed on the rotary mechanism, the impactor is then installed on the drill rod, and the drill bit is installed on the impactor. When the rotary mechanism rotates, it drives the drill bit to rotate; compressed air is used to drive the impactor to impact at high frequency, so that the drill bit impacts the rock at high frequency.

[0003] When drilling, especially medium-deep holes, multiple drill rods need to be combined and lengthened. The drill rod in operation is a slender rod structure. When subjected to the force of the propulsion mechanism, it is easy to bend and become unstable. A rod support is needed to improve the compressive stability of the slender rod. In addition, when drilling, the rock at the bottom of the hole is crushed by the impactor and the drill bit and blown out to the hole mouth by compressed air. In order to prevent the crushed rock from being blown too high by the compressed air, causing the rock to scatter over a wide range and affect the mine working environment, slag blocking is required during the drilling process. At the same time, when drilling, the initially drilled hole also needs to be effectively protected. Traditional auxiliary devices can usually only meet the needs of a single rod support or slag blocking, and cannot meet the functions of rod support, slag blocking and hole protection at the same time. It is usually necessary to install multiple auxiliary equipment on the drilling equipment, resulting in interference when installing multiple equipment in the effective space.

[0004] Therefore, there is an urgent need for an ore drilling auxiliary device and drilling equipment that can simultaneously meet the needs of supporting rods, slag blocking and slag discharge to protect the hole. Utility Model Content
