220V water injection powerful coal and rock electric drill

Water Injection Powerful Coal and Rock Electric Drill
The currently used coal electric drill is driven by a special electric motor for coal electric drills and drives the main shaft of the coal electric drill through gear transmission to rotate the main shaft of the coal electric drill to drive the drill pipe and drill bit to drill holes in the coal seam. When this kind of coal electric drill drills holes in hard coal, workers have to work hard and the drilling speed is low, which affects production. So far, there are only reports on this pure drilling type coal electric drill without the combined functions of drilling and chiseling in coal mining machinery books and magazines. In the utility model patent, it discloses the new transmission method of the coal electric drill. In the utility model patent, it discloses the water supply method and water and electricity joint control method of the wet coal electric drill.
The purpose of this utility model is to disclose an impact coal electric drill that combines drilling and chiseling to improve the drilling efficiency of the coal electric drill and reduce the labor intensity of workers.
The purpose of this utility model is achieved as follows: it is composed of an ordinary coal electric drill with an impact mechanism. The main shaft with shaft gear of the coal electric drill motor drives the main shaft of the coal electric drill to rotate through the transmission gear. At the same time, it drives the impact mechanism to generate impact and acts on the main shaft of the coal electric drill, so that the main shaft of the coal electric drill gets both rotation and impact. The impact is transmitted to the drill bit through the drill pipe to drill holes in the coal seam with the combined action of drilling and drilling.
Ordinary coal electric drills use pure drilling to drill holes in coal seams, with low drilling speed and high labor intensity. This utility model is to install an impact mechanism on a coal electric drill with pure drilling function to realize the combined action of drilling and drilling. Chiselling is currently the most effective means of crushing hard and brittle minerals, so an impact coal electric drill with a combined action of chiseling and drilling is used. Drilling can greatly improve the drilling effect of coal electric drills, reduce labor intensity, increase drilling speed, and can drill holes in harder coal seams.
