Description

Energy-saving mine drilling and reaming device Technical Field The invention relates to the technical field of energy-saving mining machinery equipment, in particular to an energy-saving mine drilling and reaming device. Background In the engineering of mine geological exploration, resource exploitation and the like, drilling and reaming are key intermediate procedures. After the mine exploration drilling is completed, the original drilling is subjected to reaming treatment to meet the requirements of subsequent geological sampling, hydrologic observation or resource exploitation, the aperture is increased through a reaming device, and the follow-up equipment is ensured to be put in and the working procedure is efficiently developed. During reaming operation, the blade of the drilling tool and the rock stratum are subjected to severe cutting friction, so that a large amount of rock dust is generated, and the dust is scattered along with the operation of the drilling tool and airflow, so that serious dust emission is formed. The dust is not only polluted by the flying dust, the visibility is reduced, the operation safety is affected, but also the dust can be inhaled by operators to induce occupational health problems such as pneumoconiosis and the like, and meanwhile, the flying dust is attached to the surfaces of a hydraulic system, an electric component and a drilling tool of the reaming device, so that the abrasion and corrosion of equipment are accelerated, the service life is shortened, and the operation and maintenance cost is increased. Therefore, the effective control of the reaming raise dust is a necessary link of mine reaming operation. In the prior art, mine reaming dust control mainly comprises spraying dust fall, and is characterized in that water is atomized through an atomizing device, so that liquid drops are combined with dust particles in a collision mode, weight is increased and sedimentation is carried out, and dust is restrained. However, in practical application, spray dust fall has a plurality of inherent defects, severely restricts the efficiency, safety and energy conservation of reaming operation, and is specifically expressed as follows: Firstly, the stability of the hole wall is reduced, and the hidden danger of hole collapse and diameter shrinkage is easily caused. When the atomized water falls dust, part of the water mist permeates into the drill hole and contacts with the peripheral soft rock stratum, the broken belt or the coal rock with high water content, so that the rock-soil structure is softened and the mechanical strength is obviously reduced. In addition, mud cakes formed by mixing water and rock scraps adhere to the hole walls, and can block subsequent exploration sampling channels and gas extraction pipelines, thereby interfering with the promotion of subsequent working procedures. Secondly, the running resistance of the drilling tool is increased, and the energy consumption is indirectly improved. Atomized water and rock dust are mixed to form viscous slurry, the viscous slurry is attached to the wings of the reamer, the outer wall of the drill rod and the threaded connection part, the friction resistance of rotation and lifting of the drilling tool is obviously increased, the load of a driving motor is increased, extra electric energy is required to be consumed for maintaining operation, efficiency benefits are offset, and in extreme cases, the slurry causes the wings to be stuck, frequent shutdown and cleaning are required, so that the operation efficiency is further reduced, and the ineffectiveness is increased. Disclosure of Invention The invention aims to provide an energy-saving mine drilling and reaming device which solves the technical problems that in mine reaming and dust raising control, the existing spraying and dust lowering technology can improve the working environment to a certain extent, but brings negative effects such as wall instability and energy consumption rise, and the like, and is difficult to meet comprehensive requirements of dust raising control effect, working safety, efficiency and energy saving. The aim of the invention can be achieved by the following technical scheme: The energy-saving mine drilling and reaming device comprises a top plate, a plurality of upright posts fixed below the top plate, and a lifting plate connected between the upright posts in a sliding manner, wherein a hydraulic cylinder is arranged between the top plate and the lifting plate, and a reaming assembly is arranged on the lifting plate; The lower surface of the lifting plate is fixedly provided with an upper cover body through a first fixing rod, a spraying assembly is arranged on the upper cover body, a lower cover body is connected onto the upper cover body in a sliding manner, a dust suction box is fixed onto the lower surface of the lifting plate through a second fixing rod, an air inlet pipe is connected between the dust suction box and the upper cover b
