Drilling device for mine engineering blasting

Abstract

The invention relates to a drilling device for mine engineering blasting, and belongs to the technical field of mining equipment. The drilling device comprises a workbench, a motor, a drill rod and a collecting assembly. The motor is arranged on the workbench, the drill rod is horizontally arranged above the workbench, and the drill rod is connected with the output shaft of the motor and used for drilling; the collecting assembly is arranged at the end, away from the motor, of the drill rod and used for collecting a mud-water mixture brought out of a hole by the drill rod; the collecting assembly comprises a support and a plurality of cleaning wheels. The support is arranged on the workbench and located under the drill rod; the multiple cleaning wheels are uniformly and symmetrically arranged on the support and are positioned on the two sides of the drill rod. According to the drilling device for mine engineering blasting, the mud-water mixture brought out by the drill rod can be collected in a centralized mode through the collecting assembly, and it is avoided that the mud-water mixture flows to the ground, and the safety of constructors is affected; the mud-water mixture on the drill rod is cleaned down in advance through a cleaning wheel, so that the mud-water mixture is prevented from being splashed to an operator, and the construction safety is improved; the drilling device for mine engineering blasting is good in protection effect, easy to operate, high in practicability and worthy of popularization.

Description

technical field [0001] The invention belongs to the technical field of mining equipment, and in particular relates to a drilling device for blasting in mine engineering. Background technique [0002] When mining a mine, blasting means are usually used to blast the ore, so as to facilitate the collection of ore. In order to improve the blasting efficiency, it is usually necessary to drill holes on the face of the tunnel before blasting, and then install explosives in the holes for blasting. Due to the complex topography of the mining face, it is impossible to use large-scale drilling equipment for construction; currently, blast drilling on the face of the mine is generally carried out with small drilling rigs, and construction personnel need to hold the small drilling rig at close range during operation. Avoid the drilling rig's own vibration to cause the hole to shift; during the drilling process, water and wind need to be sent through the drill pipe to the drill bit end to...

Problems solved by technology

Due to the complex topography of the mining face, it is impossible to use large-scale drilling equipment for construction; currently, blast drilling on the face of the mine is generally carried out with small drilling rigs, and construction personnel need to hold the small drilling rig at close range during operation. Avoid the drilling rig's own vibration to cause the hole to shift; during the drilling process, water and wind need to be sent through the drill pipe to the drill bit end to cool down, and at the same time, the debris generated by the drilling can be taken out of the hole to avoid blocking the hole and reducing the temperature. The efficiency of the drilling rig; however, the mud-water mixture derived from the hole will accumulate at the feet of the construction personnel along with the drill pipe, making it difficult for the construction personnel to stand firmly in areas with complex terrain and increase the difficulty of operation for the construction personnel; therefore, there is an urgent need for a Drilling device for mine engineering blasting with high construction safety
