Description
WO 2015/010462 PCT/CN2014/072182 Drilling and Draining Integrated Floor Anchoring Driller Field of the Invention The present invention relates to the technical field of miner's equipment, in particular to a drilling and draining integrated floor anchoring driller. Background of the Invention It is difficult to change the situation that the coal resource is a major source of energy in China in a long time in the future. As the economic construction in China is developed rapidly, the energy need becomes higher and higher; hence, the coal industry is developed continuously towards the trend of mechanization and automation. In most coal mines in China, the roadway floor heave is severely damaged in most coal mines owing to coal rock properties, buried depth, and ground stress, etc.; consequently, the use of the roadways is affected adversely and the safe production in the coal mines is hampered. Therefore, the floor strengthening task is very hard. At present, anchor bolt support is the most effective means for floor strengthening and control in coal mines in China. There is few research on anchoring equipment specially developed for roadway floor in coal mines in China at present. Floor anchoring drillers have difficulties in the drilling process, but its key function in roadway floor shoring should not be ignored. The wet drilling method used by typical anchoring equipment is to directly inject high pressure water supplied from a fixed water source into a rotating hollow drill rod, so as to extrude out the silt-water mixture from the clearance between the drill rod and the coal seam (rock strata). Such a wet drilling method has some technical problems in the floor drilling work in coal mines: firstly, the extruded silt-water mixture extruded out from the clearance splashes about as the drill rod is rotated and can not be collected, thus bringing adverse influences on the normal transportation and personnel movement in the roadways; in addition, the floor heave problem is aggravated by softened surrounding rocks soaked in water; secondly, conventional drilling methods may result in jamming and hole blocking in the floor drilling process, and the drill bit withdrawing and hole clearing work is very complicated during the drilling process; thirdly, when a wet drilling method is used for roadway floor drilling, the hole drilled in the floor surely will be filled with a great deal of water and rock powder, causing degraded anchor bolt support quality and decreased shoring efficiency, and severe water resource waste; fourthly, in roadways with harsh working conditions or restriction for use of water source, the conventional wet dust removing system may be unable to operate normally; consequently, the coal (rock) powder in the drilled hole enters into the roadway, causing increased difficulties in roadway dust control and endangering the physical health of the workers. Therefore, for those skilled in the art, there is a problem needed to be solved, i.e. how to accomplish floor drilling and strengthening quickly and efficiently while avoiding water resource waste, collecting rock powder produced in the drilling process to prevent dust harm to the physical health of the workers, and pumping out the water in the drilled hole timely and improving the shoring efficiency. Contents of the Invention 1 WO 2015/010462 PCT/CN2014/072182 Technical problem: To overcome the drawbacks in the prior art, the present invention provides a drilling and draining integrated floor anchoring driller, which can effectively control the stability of roadway floor surrounding rocks. Technical scheme: The drilling and draining integrated floor anchoring driller provided in the present invention comprises a boost air cylinder, a motor, an operating arm, a torque adjuster, and a silencer; a support connector is disposed on the boost air cylinder, a front end of the boost air cylinder is connected to a tail end of the motor, the operating arm is disposed at a connecting part between the boost air cylinder and the motor, the silencer is disposed on the periphery of the motor, a front end of the motor is connected via the torque adjuster to an optimized water circulation mechanism which comprises a transmission shaft and a filtered water circulator sleeved on the transmission shaft; the filtered water circulator comprises a rock powder collecting box, a filtering net is disposed at one side of the rock powder collecting box, an extraction and pressure pump is disposed under the filtering net, a clear water channel in communication with an outlet of the extraction and pressure pump is disposed at the other side of the rock powder collecting box, and an external water pipe port is disposed at an inlet of the clear water channel; an annular inner groove with a plurality of clear water input holes on the inner wall is arranged on a front end of the transmission shaft, and a cylindrical inner groove with a plurality of sewage absorbing holes on the inner wall is arranged on the rear end of the transmission shaft. A check valve is disposed at the outlet of the extraction and pressure pump. Beneficial effects: With the technical scheme described above, in the present invention, sewage absorbing holes and clear water input holes are arranged on the transmission shaft, so that the rock powder produced in the drilling process can be removed by injecting clear water into the drilled hole from the clear water input holes through the drill rod; thus, the drilling efficiency can be improved, the temperature of the drill bit can be decreased, and the service life of the drill bit can be prolonged. Utilizing the pumping effect of the extraction and pressure pump, the mud (a mixture of water and rock powder) in the drilled hole can be pumped into the inner pipe of the drill rod and finally absorbed through the sewage absorbing holes into the mud cavity; the mud cavity is separated into two parts by the filtering net, and the mud entering into the mud cavity is filtered and separated into rock powder and clear water; the extraction and pressure pump is mounted at the clear water side and pumps the clear water into the clear water channel and then into the drill rod via the clear water input holes; thus, cyclic utilization of the water is realized, water resource waste is avoided, and a dust removing effect is attained. In addition, the method can also be used in roadways lacking water. Thus, the mud in the drilled hole is pumped out, the shoring efficiency is improved, and the roadway construction is accelerated. The method attains the effect of wet drilling method, and further eliminates a dilemma that a wet dust removing system is unable to operate normally in a roadway where the working conditions are harsh or the use of water is restricted. The apparatus is simple in structure, has reliable performance, and has wide applicability.
