Do you know the difference between excavator auger, rotary drill and down-the-hole drill?

Original title: Do you know the difference between excavator auger, rotary drill and down-the-hole drill? What is the difference between excavator auger drill, rotary drill and down-the-hole drill? Many customers called to consult the auger and asked me to equip a set of auger for drilling 30 meters. In fact, everyone misunderstood the function of the auger. Drilling 20 or 30 meters is what the rotary drill does. Other customers will ask how to drill the rock. In fact, it is a down-the-hole drill that drills the rock. The excavator auger drill is mainly used for flexible and fast drilling, which is mainly applicable to pole drilling, tree planting and hole digging, photovoltaic hole guiding and other sites. If fast drilling is needed, the excavator auger drill should be used in Jining Intelligent Manufacturing Project. Because the installation of the spiral drilling machine is simple, the spiral drilling machine can be used after being connected with the pipeline of the breaking hammer, and the excavator accessories such as the bucket, the breaking hammer and the like can be quickly switched for use, so that time is saved, and one machine can be used for multiple purposes, while the rotary drilling machine can only be used for drilling. The auger of the excavator is light and flexible, does not occupy a large area, and follows the vehicle. The drill rod specification of the excavator auger covers a diameter range of 10 mm to 1500 mm, and the depth of the large drill hole can reach 10 meters. The auger is composed of power head, drill pipe and bracket, mining dth bit , which can be assembled on excavators, loaders and other equipment driven by hydraulic system. The power of the excavator auger is powerful. A pit with a diameter of 50 centimeters and a depth of two meters can be completed in about one minute. The efficiency is more than 100 times that of the traditional manual digging method and 5-7 times that of the rear-mounted digging equipment. The operation is simple and convenient. The excavator auger realizes the integration of driving and operation, and 1-2 operators can successfully complete the drilling work of various pits, with strong adaptability. Due to the use of loader or excavator as the equipment manufacturing platform, this type of equipment has strong cross-country performance, can be well adapted to complex terrain such as hills and mountains, and can be constructed on most of the soil such as loess layer, clay layer, gravel layer with pebbles, weathered rock layer, permafrost layer, building backfill garbage, full sand layer and domestic garbage layer. Rotary drilling rig is a kind of construction machinery suitable for pore-forming operation in building foundation engineering. It is mainly suitable for the construction of sandy soil, cohesive soil, silty soil and other soil layers, and is widely used in the construction of cast-in-place piles, diaphragm walls, foundation reinforcement and other foundations. The rated power of the rotary drilling rig is generally 125 ~ 450kW, the power output torque is 120 ~ 400kN · m, the diameter of the large hole can reach 1.5 ~ 4 m, and the depth of the large hole is 60 ~ 90 m. It can meet the requirements of various large-scale foundation construction. The drilling equipment for down-the-hole drilling is a down-the-hole drill. The essence of down-the-hole drilling is to make the impactor submerge into the hole in the process of drilling, so as to reduce the energy loss caused by the transmission of impact work by the drill rod, thereby reducing the impact of hole depth on drilling efficiency. According to the different places of use,dth rock bit, the down-the-hole drill can be divided into two categories: underground and open-air. Downhole down-hole drill can be divided into self-propelled type and non-self-propelled type according to whether it has traveling mechanism or not. According to different hole diameters, down-hole drill can be divided into light down-hole drill (hole diameter of 80 ~ 100mm), medium down-hole rig (hole diameter of 130 ~ 180mm) and heavy down-hole rig (diameter of 180 ~ 250mm).
